Time dilation

I'm new to editing wikipedia (or html stuff in general), so I don't know how to set hyperlinks. From the "Gravitational time dilation" article: "the faster the gravitational potential (the closer the clock is to the source of gravitation), the more slowly time passes". Also from the same article: "Clocks which are far from massive bodies (or at higher gravitational potentials) run faster, and clocks close to massive bodies (or at lower gravitational potentials) run slower." Time passing slower in gravitation fields is also what I remember from my academic education, although it was only a very minor subject. So if time passes slower on the ground (nearer to earth's center of mass), the ground control guys will age less than the astronaut. Hence the astronaut will have aged more, not less. So I think my edit was correct. Maybe you are confusing things with the twin paradox in special relativity which concerns a spacecraft moving at relativistic speed. Sorry for my English, it's not my native language. Greetings. (talk) 17:24, 5 December 2012 (UTC)

What you say is correct for clocks standing still in the gravitational field, but not for clocks in relative motion. The relative motion is more important in the case of low orbit satellites and astronauts. See for instance the GPS article and this sample chapter of a truly excellent book. Hope this helps. Cheers - DVdm (talk) 18:48, 5 December 2012 (UTC)
The book's chapter still arrives at the conclusion that the satellites/astronauts clock runs faster (estimated 39000ns/day). Although less faster than it would by altitude effects alone (50000ns/day) with clocks not moving. GPS article says internal reference frequency in the satellites is lower than receivers. This also makes sense only if sat clocks are faster. Seems gravitational effects outweigh speed effects in that case, and my edit was correct. But I guess I shouldn't have made a "gut decision" about stuff as non-intuitive as that. If I ever feel like editing again, I'll check some sources (and figure out how to include them). Cheers. — Preceding unsigned comment added by (talk) 15:21, 6 December 2012 (UTC)
Thought about it some more. GPS satellites are on pretty high orbits (higher grav. difference compared to ground) and moving pretty slow compared to the ISS for example which is on a pretty low orbit (lower grav. diff) and thus much faster. May well be that the speed is the more important factor then. But does it make sense to include a definitive statement in the article, if it can be both? (talk) 15:57, 6 December 2012 (UTC)
Yes, I just checked things with the equation [12] of Taylor's book. Typical GPS clocks in orbit run about 39 microseconds fast per day, whereas (at a low altitude of about 400km) ISS astronauts's clocks run about 24 microseconds slow per day. So indeed, most regular astronauts age less. If we can find solid sources for both, we can of course include them in the article, but we can't rely on calculations we make ourselves, per wp:NOR and wp:CALC. Cheers - DVdm (talk) 16:46, 6 December 2012 (UTC)
F.w.i.w, I created this little thingy:

Daily satellite time dilation.png

It shows the daily time dilation (gain or loss if negative) in microseconds as a function of orbit (assumed circular) radius r = rs/re where rs is satellite orbit radius and re is Earth radius. At r = 1.497 there is no time dilation, i.o.w. the gravitational and velocity approximations cancel. IIS astronauts fly below, whereas GPS and Geostationary satellites fly above.

Note(to self—probably), see fig 2, p 16 of Ashby's Relativity in the Global Positioning System. - DVdm (talk) 21:17, 13 January 2013 (UTC)

TRH: What is thought of by readers as astronauts "most" of the time may be the more exotic moon voyages. Here is a reference from an excerpt published in TIME magazine that moon travellers age more;,9171,839785,00.html Going with a time descrepancy per orbit alone may be somewhat illuminating but ignores acceleration periods needed to get off of and get back to the earth. Only a full computation including this could verify if a specific ISS visitor aged less overall. The article clearly should not state astronauts age less, when moon travellers aged more. I do not know why this discussion is not directly on the Wikipedia time dilation web site. (talk) 19:26, 21 February 2013 (UTC)

(moved your signature to the end, hope you don't mind)
Meanwhile I had added the above image to the article. It fully complies with Asbhy.
I have now tweaked the lead caption of the article, adding the ISS specification to the astronauts, and moved the Ashby source citation up. I have also added the ref here. Everything seems to be correct and properly sourced now.
The Time magazine article, which is of course not really a wp:reliable source, is now not relevant, as the caption specifically talks about ISS astronauts. Perhaps it's better not to complicate things, and stick with the good sources, so to speak.
I agree that this discussion should have been held on the article talk page. Blame in on history :-)
Cheers! - DVdm (talk) 19:48, 21 February 2013 (UTC)

TRH: Yes, leading caption is fixed. However, the new caption needs work. The primary issue is an irritating tiny detail. From the article, with respect to proper time, satellite clock tick rate is; (ds1/dt)^2 = 1-2GM/(r*c^2)-v_perp^2/c^2, where orbit radial velocity is zero. A clock on earth at the North Pole has; (ds2/dt)^2 = 1-2GM/(Re*c^2) For classical mechanics, equating F=ma for the orbit's circular acceleration and gravity yields v_perp^2=GM/r so the satellite simplifies to (ds1/dt)^2 = 1-3GM/(r*c^2) Now equating the two clocks gives 2/Re=3/r, so r=(3/2)Re. Therefore, in lieu of original research, one should report 1.5 Re as where the two clocks tick at the same rate. But this caption claims 1.497 is a better answer. There is nowhere near the plot resolution to argue about the 3rd decimal place. Is 1.497 even really correct? What mystical effect does the author have secret knowledge about? (talk) 18:31, 22 February 2013 (UTC)

The value 1.497 is based on equation [3] on page A-3 (or [12] on page A-6) of Taylor and Wheeler, setting it to 1 and solving for rs (satellite radius), and using at least 4 digit precision for the numerical values. This equation is directly drawn from the Swartzschild metric in equation [1].
When we put vEarth = 0 in equation [3], ignoring the fact that equatorial ground based clocks are moving in the Earth centre based inertial reference frame, we get of course the exact value 1.5 that you mention above. That is in essence (almost) what the above analysis does when comparing with a pole based clock. However, when doing that, one should also use the polar Earth radius (6371 km) in stead of the equatorial radius (6378 km), which would reduce the 1.5 back to 1.498.
Anyway, Ashby's source says that "the effects cancel at a ≈ 9545 km", which of course perfectly corresponds to ≈ 1.497 equatorial Earth radii, so the value 1.497 is indeed backed by the source. Note that we can do this per trivial routine calculation 9545/6378=1.497 (see wp:CALC). So I think it would be safe to leave the caption as is, since "Earth radius" is usually assumed to be the equatorial one is such context, but I have tweaked the caption anyway. Thanks for having drawn my attention to this. Cheers - DVdm (talk) 10:47, 23 February 2013 (UTC)

TRH: The sources you quote are expanding expressions into series and dropping lower order terms, but NOT dealing with the earth eccentricity. A-3 Eqn [3] is identical to a ratio of the two equations I wrote for (ds1)^2 and (ds2)^2, and A-3 Eqn [9] gives the identical satellite velocity equation I gave. You are saying 1.497 is derivable from the identical equations that I am showing you actually yield 1.5. Do you agree that the earth equator rotational velocity is negligible, for the 3rd decimal? You indirectly mistakenly suggest that the more precise north pole gravity term is obtained by plugging in a smaller R in the spherical 1/R formula. In the limit of large eccentricity the earth becomes a pancake, the two poles touch each other, and there is no gravity at all (on the surface at the north pole). But for your approach gravity is going to infinity, because you keep plugging in a smaller R into 1/R. The basic reality is a caption, surrounded by Wikipedia equations that point to 1.5 Re, states 1.497 for reasons that are not stated. What is the point in going to the 3rd decimal? Readers are best served by a caption that states (3/2)Re (or an altitude of Re/2) and avoids the complication of new flavors of Re. The equatorial versus average and polar earth radii distinctions are too detailed for the Wikipedia article in the first place, and even the more involved references quoted in this discussion do not cover it. (talk) 13:27, 25 February 2013 (UTC)

If one sets the "earth velocity" to zero in the Earth centre based inertial reference frame (see article Earth-centered inertial), one ignores the fact that the Earth based clocks are not inertial, and one gets 1.5 exactly. Not ignoring this, and thus more correctly applying the general relativistic equations, gives the value 1.497. That is certainly significant in an article about time dilation, and specially relevant in the section about the combination of so-called gravitational and kinematic effects, which are of course in turn both approximations of the originating Schwarzschild metric. Ignoring a significant part of the kinematics would be highly inappropriate in that context.
But no worries, the 4 digit expression 1.497 in the caption in the article is directly derivable from (and tracable to) the 4 digit expression 9545 in the Ashby source (see policy wp:RS) in the same caption. The rest is just informal chat on my user talk page. - DVdm (talk) 14:30, 25 February 2013 (UTC)

TRH: You correctly point out the earth's velocity is not negligible to the 3rd decimal for a clock at the equator. Assume we stay consistent with the segment of the current Wikipedia article where the caption is placed by NOT resorting to earth eccentricity. For the north pole we get 1.5*Re and for the equator I get 1.4974*Re = 1.4974*6371 kM = 9540 km, and this rounds to 1.497*Re. Perhaps the caption could state "the clocks agree for a satellite orbit at 1.5*Re for an earth clock at the north pole and 1.497*Re for an earth clock at the equator". If sticking to only 1.497*Re, at least specify that the earth clock is on the equator. Note the current caption does tell you to use an equatorial value for Re, but does NOT explicitly tell you the earth clock must be on the equator for 1.497*Re to be correct, which may be confusing. It is a dubious idea to introduce eccentricity with only indirect motivation from a reference that states APPROXIMATELY 9545 km. Mentioning a distinct "equatorial" Re is unfortunate because this references eccentricity and thus gives the false implication that references are taking eccentricity into account to get this 0.003 correction, when in fact it is primarily a rotational velocity effect. (talk) 15:45, 25 February 2013 (UTC)

Well, the value in the caption is properly sourced, so, per policy, we don't have to worry about that. Whether we understand it, or accept it, or not, is of no importance for Wikipedia.
All the above here merely serves to help you understand that the value is correct. We don't have to do that here in Wikipedia. What matters —per policy— is that the thing is properly sourced in the article. If you are not convinced by my additional remarks, then that's okay. No problem and no worries. Cheers - DVdm (talk) 15:48, 25 February 2013 (UTC)
Anyway, contrary to what you suggested now, we do not have to explicitly tell that the earth clock must be on the equator. The Ashby source doesn't say it either, because the clock can be anywhere. All clocks on the geoid are synchronised. As I have shown before, a clock on the pole is synchronous with a clock on the equator (remember that 1.498 above), and in fact with every clock in between, provided it rests on the ground and rotates with the earth. The one on the pole does not rotate but it is closer to the center. The two effects cancel everywhere. - DVdm (talk) 17:31, 25 February 2013 (UTC)

A non-spinning earth has one unique average sea level at the equator and poles. Adding earth rotational velocity to get its time dilation impact is fine, but this change also must create an elliptical sea level. The caption specifies both an equatorial Re instead of an average Re, and 1.497 instead of 1.5. Both of these corrections are not just spinning earth effects but also equivalently elliptical earth effects. If only the equatorial and polor sea levels are given, the equatorial velocity can be determined. The intent is for the caption to incorporate an earth velocity time dilation correction, but given that an elliptical earth surface gravitational potential was not used, the referenced computation was not accurate enough to assert an earth velocity effect. Using 1.5*Re in the caption drops the pretense of reporting a computation as being more accurate than it may actually be. (talk) 18:47, 26 February 2013 (UTC)

If the source had said that "the effects cancel at a = 9567 km", then we could write 1.5, but the source says "the effects cancel at a ≈ 9545 km", so we must write 1.497 instead of 1.5. You suggest that we put wp:original research in the article, which is a no-no in Wikipedia. - DVdm (talk) 18:58, 26 February 2013 (UTC)

Stating 1.498*Re (=9544 km) and leaving out the equatorial earth radius (as you point out, anywhere is OK) which yields 1.497*Req (=9548 km) is closer to the source. Handing out 2 or 4 decimals of precision in a caption is partly a matter of discretion, where you look at the source and try to figure out how much precision was intended. (talk) 19:07, 26 February 2013 (UTC)

The source has 4 decimals of precision. Any deviation from that when using the source would amount to wp:original research. - DVdm (talk) 19:11, 26 February 2013 (UTC)

Lets go for 5 digits precision. Above is a reference where the International Astronomical Union "Terrestrial Time" scale (between Eqns 18 & 19) is given as ds2/dt = 1-alpha, for alpha = 6.969290134*10^(-10). For break even equate this to ds1/dt = sqrt[1-3GM/(rc^2)]

r/Requator = (3/2)*(GM/c^2)/[alpha*(1-alpha/2)*Requator] = 1.4942

Sticking to 1.497 misses the earth rotational velocity + ellipsoidal surface gravity correction by 50%. (talk) 20:06, 26 February 2013 (UTC)

Regarding "For break even equate this to ds1/dt = sqrt(1-3GM/(rc^2))", see wp:NOR and wp:SYNT. - DVdm (talk) 21:01, 26 February 2013 (UTC)

I concede that one should also properly give a satellite flying over the equator an elliptical earth (GM/r)*(1-J2*(Re/r)^2) correction for J2=1.08263*10^(-3), and this does get even more involved in original looking stuff. When I did this I got 1.493*Requator. The point is not to replace 1.497 with 1.494 or 1.493, but rather to question what value and motivation exists to assigning 4 digits of precision to the original source. The author may have filled in preceding digit places just to get to the "km" symbol, and did so consistent with terms that were ignored along the way, just so that ***a reader who followed through with the same approximations and repeated the computation would not be frustrasted by getting a different answer***. We cannot telepathically decipher the intent of the author as otherwise. (talk) 21:25, 26 February 2013 (UTC)

Regarding "The author may have filled in preceding digit places just to...": see wp:NOR and wp:SYNT. - DVdm (talk) 21:28, 26 February 2013 (UTC)

TRH: Thanks for bearing with me. I think I resolved the mystery of why Ashby's 9545 km result is missing a quadrapole potential correction, which normally must come along with a rotating earth due to the rotation's impact on sea level. Clearly it has troubled me that I could not recover 9545 km when only low order polynomials are involved. Since my last writing,

  • I extended all my constants to higher precision (using c=3*10^8 was the primary issue).
  • Ashby's equation 85 has the right elliptical correction, but there is a 7 where I get a 5, so I just fudged over to the published 7. When the clock's agree, the frequency shift and time dilation discrepancies go away, so Eqn 85 is better for getting break-even.
  • A circular orbit has no eccentricity. Flying over the equator I get 1.4948086*Requator=9534 km, still not recovering the 3rd decimal. So the thought occurs to me; Ashby is much more interested in GPS technology, not esoteric break-even. There is nothing in his orbital time dilation plot indicating a specific satellite inclination, and there is one data point for a GPS satellite. A unique curve needs a unique inclination. What if I plug in 55 degrees since that is correct for GPS satellites?

I got 1.496511429*Requator=9544.955 km. It just so happens that 55 degrees decimates the elliptical potential term. Whether it has a 7 or 5 factor doesnt matter, due to a leading factor of (1-(3/2)*(sin(2*pi*55/360))^2) = -0.006515107494252. So the current caption 3rd decimal is AOK for an orbit tilted at 55 degrees (where 90 orbits the poles and 0 orbits the equator). For an orbit going over the equator, Eqn 85 indicates the 3rd decimal is off (should be 1.495 and not 1.497). (talk) 20:47, 27 February 2013 (UTC)

Nice work. If we can find a good independent-Wikipedia-kinda-non-original-research-source that backs this, we can modify the caption and let it rest. In the meantime we'll have to settle for Ashby's decimal. Say hello from me when you send him an email ;-) — Cheers - DVdm (talk) 21:49, 27 February 2013 (UTC)

Mass–energy equivalence

I do not believe you had any right to remove my addition to the Mass-Energy equivalent page. I am not Wiki-savvy and I know people like me are routinely abused by more tech-savvy usually establishment protected editors. Olinto De Pretto published E=MC2 before Albert Einstein. All of Europe knows Einstein was a fraud and plagiarist. (talk) 19:53, 28 March 2013 (UTC)

The source that you used ([1]) with your edit, is not a reliable source for our scientific articles. The site's motto is "Your guide to Italy & Italian Culture on the Web. Enjoy as you learn more about the traditions, heritage and way of life that make Italians who they are." Regarding reliable sources, see wp:RS, and perhaps also wp:FRINGE.
The Guardian article you added here above ([2]) and which I moved in front of your signature, seems to contradict your thesis. Note its conclusion: "De Pretto deserves credit if his contribution can be proven. Even so, it should not detract from Einstein." Also note that the author is a journalist, not a physicist, so this seems not to be a reliable source either.
If you feel that my revert of your addition was not warranted by our policies and guidelines, perhaps a better place to discuss it, would be the article talk page at Talk:Mass–energy equivalence. See wp:BRD. Cheers - DVdm (talk) 08:12, 29 March 2013 (UTC)

Replaced {{Uw-vandalism4}} with {{Uw-unsourced4}} on User talk:

Just to let you know, I replaced your {{Uw-vandalism4}} message with {{Uw-unsourced4}} on User talk: because the edits were primarily an addition of unsourced material, rather than an intentional effort to compromise the integrity of the encyclopedia. —DragonLord(talk/contribs) 19:15, 6 April 2013 (UTC)

Yep. Thanks and cheers - DVdm (talk) 19:17, 6 April 2013 (UTC)

DVdm, I don't know why

DVdm, I don't know why you think my Edit on Johannesburg requires discussion. It's an urban myth that JHB is the world's largest man-made forest (and there's no citation supporting the myth). It's easy to find out that China has a forest with 50 billion trees planted over 500,000 sq km, compared to Johannesburg's alleged 10 million planted over 500 sq km.

Wikipedia is unfortunately treated as an authority in its own right, and results in perpetuating myths like this very quickly. (Many blogs now repeat the myth, having found the "fact" on Wikipedia) — Preceding unsigned comment added by Michaelandsandy (talkcontribs)

Hi DVdm, thanks for undoing the vandal's work. In case you didn't notice, 196 is a proxy server. The guy is using numerous IPs via proxy servers to evade a block and Materialscientist and Boing have been among the admins dealing with him. Most of his IPs have been blocked.

Edit war using..

Hello, I see you have discovered the edit war too? I think it would be best to block the user now, he/she shows no sign of stopping. I myself have tried to reason with them but they consistently demand on editing again. Thanks Uh oh Uh Oh Again (talk) 20:19, 9 April 2013 (UTC)

Reported and notified. - DVdm (talk) 20:25, 9 April 2013 (UTC)

What was this?

The user's edits here were not vandalism, still you named them as "un-constructive", please learn to label edits correctly. Faizan (talk) 11:29, 2 April 2013 (UTC)

To you! Faizan (talk) 11:39, 2 April 2013 (UTC)
Hi, I stumbled in here because of the ANSI C vandal but thought I could help clarify:
Many Muslims consider it a religious obligation to say "peace be upon him" after every mention of a prophet's name, just like in the reverted edit. So it was almost certainly a well-intentioned edit that went against WP style guidelines. But I can see how it would look like a joke or vandalism to someone unfamiliar with the tradition. Cheers! Rizome (talk) 01:47, 22 April 2013 (UTC)

hope you don't mind

The following discussion is closed. Please do not modify it. Subsequent comments should be made in a new section.

-I undid your deletion. After reading the explanation of why the translated material appears to be copyvio-(but is not), I am satisfied that the editor posted the material in good faith. Also, did you happen to notice the artist's awards section? More information about this artist does not appear to me to be "fluff" or overly promotional.
Is Wikipedia running out of bandwidth? Otherwise, this slashing & burning of content appears to me as vandalism as well. (talk) 13:31, 10 April 2013 (UTC)

I do mind. This wp:BLP article has a prominent header: "This article needs additional citations for verification". Adding more unsourced material does not help, quite on the contrary. I have reverted your edit. - DVdm (talk) 13:50, 10 April 2013 (UTC)

If the material was translated and donated wouldn't the untranslated information be the citation? I did not read the original article that was accused of being a translated copyvio since it seemed that there was enough evidence to support that. (talk) 13:55, 10 April 2013 (UTC)

This is a schoolbook issue of wp:RS and wp:BLP, not one of copyvio. If all of this is true, then sources should be easy to find and properly document. That is the only way to get rid of the {{refimprove}} template on Anton Goosen article. Consider it your mission. Good luck! - DVdm (talk) 14:05, 10 April 2013 (UTC)
no thanks-I'll take-out the overtly promotional stuff. The source of the info. and citation, with permission has already been discussed on the talk page24.0.133.234 (talk) 14:09, 10 April 2013 (UTC)

Reply from someone just refreshing their algebra

Hi DVdm,

I am writing concerning your removal of my edit on the discriminant formula.

In the formula the imaginary number already accounts for the discriminate being negative as it is the square root of negative one and by the properties of multiplication under a square root it can be taken outside. I removed the secondary negative symbol before the delta symbol because before it read:

+ or - i[square root(-delta)]/2a

but it should read:

+ or - i[square root(delta)]/2a

because like I said the i already accounts for the negative value in the discriminant.

Please excuse my ignorance if I missing something totally obvious and also my sorry excuse for trying to write mathematical equations online (I probably used all the wrong separators).

Thanks — Preceding unsigned comment added by (talk) 18:21, 10 April 2013 (UTC)

If Δ is negative, then -Δ is positive and the square root can be taken, such that √(Δ) = i √(-Δ). - DVdm (talk) 18:34, 10 April 2013 (UTC)

Trigonometric interpretation of a cubic with three real roots (JPEG -> PNG)

Thank you for your effort, but please read WP:PIFU#Do not save diagrams as JPEG ("do not simply save the JPEG as PNG"). ;-) And when you upload replacements, please make appropriate changes on the original file description page and provide useful description and source information for the new file (like I did now for the original and the new).

Trigonometric interpretation of a cubic with three real roots.png
I hadn't really saved the jpg as png, but created a new png from a fresh screenschot op the jpg, which of course resulted in the the same pretty bad looks. I should have put more time in doing it right. Thanks for the advice and sorry for the extra effort.
By the way, I made another little change for colour consistency. Before: black dashed to A and B, red to C and θ-rotated points. After: Blue to A, B, C, red to θ-rotated points. Cheers - DVdm (talk) 09:02, 13 April 2013 (UTC)
OK, now it looks more evident. :-) If you could redraw it in SVG (using an actual cubic curve instead of wry splines)...
BTW, as I understand, the vertical line going through the center of the circle should pass through the center of symmetry of the cubic curve. It would be good to show this relation also.

Re: Rowenna Davis

My comments on the edit of the Rowenna Davis page reflects the original guidelines for personal profiles on Wiki. Writers, Artists etc who had published / exhibited major works, or published numerous referenced works, Recording artists, major Political figures, and celebreties, were deemed to warrant a page. I have not checked the recent wording for biographies, however I would contend that Rowenna Davis does not qualify.

Admittedly she has appeared as a Panelist of a Sunday Lunch Time Political programme, is a sitting Labour Cancilor, and contributes articles to the NewStatesman (a left-wing party-political journal), however there 1,861 London Councilors, of which a number appear regularly in print, on television, and on the radio. These include professional Journalists, accomplished Businessmen, and high profile individuals. Very few of these people have a Wiki page due to the guidelines, so why does Rowenna Davis?

I can understand that someone decided to create the page, and that without knowing much about the British Political System one might assume what is written about her inplies something of importance, however baring in mind there are 1,860 other London Councillor, with many more County (1,859), Unitary (3,123), Borough (2,445) and Disrict (8,903) Councillors, many of whom have held more senior local office, I think that the page should be removed - otherwise you will see a good deal of similar pages - which adds nothing to the richness of Wiki. — Preceding unsigned comment added by (talk) 23:30, 15 April 2013 (UTC)

(talk page stalker) David, I believe you're being disingenuous with us. If you have read the Wikipedia guideline on original research, you should know that sourcing your analysis of the Bible to the Bible itself is not helping. You need to provide a reference to a reputable writer (one who might be expected to know about such things, such as a recognized scholar in the field) who has read the Bible and come to the interpretation that you are trying to insert. And the reference to (a provider of electronic oscilloscopes) is just pointless, and more proof that you are being disingenuous. WikiDan61ChatMe!ReadMe!! 22:01, 13 May 2013 (UTC)
Disingenuous and Thanks again

Thanks to both of you helping me. No. I apologize for sounding disingenuous. I'm not very smart. I thought the rules said that Wikipedia was a way for everyone to give their input on what things meant to give a better meaning of it, and that like others, you and myself have changed them are showing that eventually the best meaning will be there and continue to develop over time. I thought that's what I read the founder of Wiki say on Wiki once. I apologize if I got it wrong. I wrongly thought sourcing Scopes was a good way for what I said. I understand. I'm not going to change it anymore like I told WikiDan61. Please don't block me. If I can learn anymore today let me know. As I told WikiDan61, for the rest of the pages on the mark of the beast and the number of the beast being problamatic according to how I was, yes, a lot of the pages would need to be erased then. But again, personally, I'm happy it says what it says either way. Again, thanks for everything. I'll take both your advises. Thanks again.DavidWayneJohnson (talk) 22:22, 13 May 2013 (UTC)

I notice you have reverted vandalism on my user page also. Thank you. VanguardScot 04:42, 26 May 2013 (UTC)

As a member of ...

As a member of the Prescott Visitor Bureau I would simply ask that you stop deleting this entry. Dave was born here and is a well known resident. Come see us some time, I'll introduce you to him. Thanks, Sam Thomas — Preceding unsigned comment added by (talk) 20:57, 25 May 2013 (UTC)

Sure, but as a Wikipedia contributor, you need wp:reliable sources for your edits. Continuing to insert unsourced challenged —see wp:BURDEN— content will get you blocked. Good luck. - DVdm (talk) 21:02, 25 May 2013 (UTC)\

After reading the long list of entries above from others trying to add useful information I now see that a little power really goes a long way around here. Perhaps some fresh air would be in order for a person such as yourself. You appear to be heavy handed in your duties. I could see your point if I were adding something incendiary but I simply added a note about a local resident who just set a new speed climbing record and was featured in our local paper today. He is also a regular in our local community performing for elderly residents and those in our hospital. I just don't see how you can dismiss him so easily? — Preceding unsigned comment added by (talkcontribs) 21:10, 25 May 2013 (UTC)

It's easy. Get yourself a wp:reliable source that establishes this person's wp:notability, make sure there's an article about him in Wikipedia, and you're in business. - DVdm (talk) 21:40, 25 May 2013 (UTC)

The edits of Mrm7171

Thank you DVdm. I would like to discuss edits with Mrm7171 but it is strange that he/she declines to discuss.Iss246 (talk) 15:02, 23 May 2013 (UTC)

Quite indeed. You did your utter best trying to discuss, but this seems not to work. A different approach is clearly called for here. Cheers - DVdm (talk) 15:49, 23 May 2013 (UTC)

Hi. Are you an administrator? What power apart from an editor, like me, do you have may i ask? Did you receive my warning regarding your undoing of my genuine, good faith changes and you clearly engaing in an edit war, by deleting, blanking vanalising my new entries? Hoping you might reply. Up to you, if you have any thing to add? Mrm7171 (talk) 09:27, 30 May 2013 (UTC)

Please ask me for my permission or discuss before deleting my good faith additions. Mrm7171 (talk) 09:36, 30 May 2013 (UTC) Take this as your final warning before I put a formal complaint in. I;m sorry, but you keep deleting, undoing without discussing. Thanks. "Talk constructively with me, showing me some respect though if you would like." Thanks. Seriously, I have posed some interesting questions here. Are you a Psychologist yourself DVDm Mrm7171 (talk) 09:36, 30 May 2013 (UTC)

Replied on your talk page. Please stop duplicating your messages all over the place. - DVdm (talk) 09:40, 30 May 2013 (UTC)

Just contacting you here relating to your deletion of my good faith work. I noticed you also used some sosftware to this undoing of my good faith work.

Rollback is available to all administrators and can be given to other users on request, subject to the approval of an administrator. A user who has been assigned this right explicitly is called a rollbacker. There are currently 1,448 administrators and 4,850 rollbackers (6,298 total), not including global rollbackers who have been assigned the right across all Wikimedia projects.

Standard rollback may only be used in certain situations – editors who misuse standard rollback (for example, by using it to reverse good-faith edits in situations where an explanatory edit summary would normally be expected) may have their rollback rights removed. Since rollback is part of the core administrator tools, an admin could be stripped of their administrative privileges to remove those tools.

Do you have permission DvDm ? Are you acting in bad faith here? Mrm7171 (talk) 09:57, 30 May 2013 (UTC)

Don't worry about my permissions. If one is warned multiple times not to make unsourced edits, but to find sources and discuss them with others, yet still persists adding similar content, then one is considered to either act in wp:bad faith and to refuse to take a point, and/or to have wp:NOCLUE about our policies. In both circumstances one usually ends up blocked. Trust me. Go to that article talk page and discuss, and you'll be fine. - DVdm (talk) 10:08, 30 May 2013 (UTC)

hmm...i am very worried about you using this software dvdm i ask again..."(for example, by using it to reverse good-faith edits in situations where an explanatory edit summary would normally be expected) may have their rollback rights removed. Since rollback is part of the core administrator tools, an admin could be stripped of their administrative privileges to remove those tools." Please respond..rather than avvoid..not sure if you understanbd the proper use of this software rollback i do not believ e you are authorised to use it?> breaking rulesMrm7171 (talk) 02:05, 31 May 2013 (UTC)

Also please note, any additions i have made are in good faith and you are personally bordering on breaking the three deletions rule in 24 hours. I have already warned you.

This is your last and only warning. You may be blocked from editing without further warning the next time you vandalize a page, as you did with this undo edit to Occupational health psychology. Mrm7171 (talk) 02:07, 31 May 2013 (UTC)

Don't make empty threats. Your edits may or may not be in good faith, but you have repeatedly been asked to discuss and to provide sources. You accuse others of having an agenda and engaging in edit warring, but fail to recognize that you have an agenda as well, and your pugnacious attitude has been turning people off. I'm glad that you have finally realized that you need to consolidate the discussions in the article talk page rather than spreading them out across multiple user talk pages. Stigmatella aurantiaca (talk) 03:38, 31 May 2013 (UTC)

Thanks Stigmatella aurantiaca, for your comments. I'm only a new user. Have listened to suggestions from other editors and made changes according to community rules.

Have asked Itszippy what to do about an editor, ISS246, or in fact any Editor for that matter, who blatantly refuses to accept a large and solid group consensus against posting something signiicant, particularly in an article relating to a profession like medicine, engineering or psychology etc etc. Everyone, way before me, (in fact for 4 years now) has disagreed with him strongly, often very strongly, much more strongly than I have. However it just went ahead and did it anyway, thinking he ius right and all other community members are wrong, as if Wikipedia is his private website! Have you any practical advcice, on top of Itszippy's suggestions, instead of judging me please?

You, like many others here seem to have a lot of experience and know all the rules and regulations. So what do you think? If we could all just go against the broad consensus, and post what 'we' want, what would Wikipedia become? Mrm7171 (talk) 23:25, 31 May 2013 (UTC)


I have a complaint about Mrm7171. He plays a double game. I try to discuss edits with him on his talk page. Then he goes ahead and makes edits without discussing them. And finally writes:

(diff | hist) . . m Occupational health psychology‎; 02:54 . . (+57)‎ . . ‎Mrm7171 (talk | contribs)‎ (Just made a couple of very minor additions. Did not delete or undo anyone elses edits. Please discuss with me on my talk page to come to consensus.Thanks)

(diff | hist) . . m Occupational health psychology‎; 02:51 . . (+9)‎ . . ‎Mrm7171 (talk | contribs)‎ (One word added. No deletion of any other editors work made out of respect. We need to discuss. Please use my talk page. Please don't just remove. Thanks)

(diff | hist) . . m Occupational health psychology‎; 02:50 . . (+25)‎ . . ‎Mrm7171 (talk | contribs)‎ (Please discuss on my talk page iss246 rather than undo my minor edit or engage in edit war. Please don't iss246. It's better to discuss than you delete. thanks)

Meanwhile, he includes text that occupational health psychology is a subfield of i/o psychology when I have labored on his talk page to explain that OHP is not a subfield of i/o psychology just as i/o psychology is not a subfield of social psychology and psychometrics or that health psychology is not a subfield of clinical psychology. I view what he has done as bad faith. This includes his groveling, with purposeful bad grammar, about how he has been picked on on May 26, 2013:

Extended content

[[Category:{{unblock| Thats cool. I'm still very unclear abvout talk page and feel administrator may have acted a liottle demeaning.

I've been patient with him. I find him full of bad faith. This sing-song of "let's discuss" and then he goes ahead and makes a bold move without sources that OHP is a subfield of i/o psychology. I think he should be barred from Wikipedia for his double-talk.Iss246 (talk) 04:02, 28 May 2013 (UTC)

  • User:Iss246, Hello, and I am sure User:DVdm won't mind me jumping in here. Take a look at WP:DE and read through WP:AGF. Also, sorry to say, that although I empathize with your efforts, and even though Wikipedia does not "require that editors continue to assume good faith in the presence of obvious evidence to the contrary", it is best to remain civil and not explicitly say another editor is acting in bad faith. An administrator may say that when meting out punitive action, but editors are strongly encouraged to not accuse each other of acting in bad faith. Yes, I understand your frustration. Those of us who edit for accuracy, and according to guidelines and policies have encountered other editors that are not easy to deal with. Just hang in there and stay the course, and you will do well. It is best to let the Administrators handle the tough stuff. ---- Steve Quinn (talk) 04:58, 28 May 2013 (UTC)
  • I reverted the last edits asking the user to join the article talk page discussion (I made two typos in my edit summary, sorry). I also left a little note on the blocking admin's talk page. Assuming bad faith might not be called for yet, but I think we can safely assume wp:NOCLUE here. - DVdm (talk) 07:02, 28 May 2013 (UTC)
  • I was just trying to help out with a difficult editing situation. Now, all I can say is, "if it looks like a duck, swims like a duck, and quacks like a duck, then it probably is a duck." WP:DUCK (as it relates to WP:DE ). ---- Steve Quinn (talk) 00:27, 1 June 2013 (UTC)

Dvdm. I strongly request you take the comments I made soon after joining Wikipidia, and you have for some reason directly pasted on your talk page below? I ask you to delete the entire paste you made please. Thank you.Mrm7171 (talk) 00:30, 8 June 2013 (UTC)

(I moved this comment to the bottom of the thread - see talk page guidelines.)
I haven't pasted anything on my talk page. The above comments that you made, were quoted here by someone else. Everything here will soon be archived automatically. - DVdm (talk) 12:08, 8 June 2013 (UTC)

Can you tell me please what the Wiki policy is regarding the placement of other's comments on editor's own talk page when done so in possible bad faith or a means of personal attack?Mrm7171 (talk) 23:34, 10 June 2013 (UTC)

Also Dvdm, my opinion is that all articles require accuracy, currency, knowledge, and be factual and free from bias and be edited for the benefit of the greater Wikipedia community and readers. This is particularly true, in my opinion, with articles, relating to international professions, like psychology, medicine, etc etc..where accuracy, standards and broad-based acceptance of standards and protocols, within each profession apply. I note you have possibly been working in unison with another editor, to delete 'any' much needed revisions of a couple of articles I have ever attempted. In my still limited experience of Wikipedia, it is the communities resource, and articles needs accuracy and currency and not in any way, be misleading to the community. Also deleting other people's important changes sometimes, and without discussing with them your intention, does no good for the wikipedia community and can lead to unneccessary conflict, when prior discussion about edits could avoid any such unneeded conflict. Based on a quick look at comments from many other editors on your talk page here, you seem to delete a lot of other editors work, in a lot of different areas So, please, for the last time, I ask you to discuss with me, before you for some reason, 'blindly' delete my edits, in future. Thanks. Mrm7171 (talk) 23:34, 10 June 2013 (UTC)

(I moved this comment to the bottom of this thread - see talk page guidelines.)
  • As far as I can see, the comments were not made in bad faith or as a personal attack. Quite on the contrary, I think they were made in despair. If you think they were made in bad faith, you need to go to wp:ANI (Wikipedia:Administrators' noticeboard) and/or to wp:DR (Wikipedia:Dispute resolution). This was explained to you before here, here and here.
  • When you mess up an article talk page (as you did with this edit), I will repair it (as I did with this edit). ItsZippy already explained that with this message on ItsZippy' talk page. After this warning, again (with this edit) you added off-topic content, which I removed here. If you disrupt a talk page again, I will not discuss it. I will repair it, and then I will report you for continued talk page disruption after multiple warnings.
  • If you have a problem with my conduct, you can go to wp:ANI and report me.
Please do read and try to abide the comments given by ItsZippy, and you will be fine. While at it, have a look at Wikipedia:Etiquette as well. Good luck. - DVdm (talk) 08:20, 11 June 2013 (UTC)

Talk-back for your edit on Discrete Cosine Transform page

Hi, You delete my external link on discrete cosine transform page. It is just a tutorial explaining the DCT. You do not delete other external links but just mine. Why? This discrimination is based on what? There is another external link, for example, You do not delete this but just mine? Why? I contacted the user Ktr101 and you can talk to him if you need to do so. He looked at my tutorials and could not see why you make discrimination specifically for my tutorials. It is based on race, religion or ethnicity or something else? — Preceding unsigned comment added by (talkcontribs) 22:14, 26 May 2013 (UTC)

Please sign your talk page messages with four tildes (~~~~). Thanks.
See wp:ELNO item 11: "Blogs, personal web pages and most fansites, except those written by a recognized authority." You are not a recognized authority, and Wikipedia is not a place to promote our own work: see wp:NOR and wp:COI. So, to answer your question, it is based on Wikipedia policies. - DVdm (talk) 06:33, 27 May 2013 (UTC)
Also note that, if you think that other links might be inappropriate, the best thing to do would be to open a little section at the bottom of the talk page Talk:Discrete cosine transform, and propose to delete. These links have been there for a while, so it's best to discuss their removal with the other contributors. Don't forget to sign your messages with the four tildes (~~~~). - DVdm (talk) 13:46, 27 May 2013 (UTC)
I read your message. You are making discrimination. Are you recognized authority about DCT? What do you know about Discrete Cosine Transform at all? Did you read my tutorial? It is just a resource that explains a topic. It is not an advertisement or a product. You do not provide any scientific reasoning but your personal opinion. I will complain about you to everywhere that is possible because you think something and you decide without any objective reasoning. What you do here is discrimination and this is illegal in the United States. — Preceding unsigned comment added by (talk) 19:42, 27 May 2013 (UTC)
We put talk page messages at the bottom and we sign our talk page messages — see wp:talk page guidelines. Please read them and try to follow them.
We don't have to read anything, specially not some contributors' private work. It is your work and you want to add it as an external link. That is a no-no here: see —again— wp:NOR, wp:COI, wp:ELNO item 11, and as far as I know, you are not a recognized authority (yet).
I do not have to provide any scientific reasoning, and I do not provide my personal opinion here. What I provide is pointers to Wikipedia policies and guidelines. Just read them. If you like to change them, go ahead, try to edit the policies and see what happens.
Seriously, do some reading before you accuse people of discrimination or bias based on race, religion or ethnicity. That can be taken as a wp:personal attack and there's another policy about that. Click the link to read it. - DVdm (talk) 20:17, 27 May 2013 (UTC)
He isn't discriminating against you here. I merely said I couldn't see why he removed the link, but that doesn't mean that I know everything and it keeps open the fact that he may have removed the link with a rationale that I do not know about. If you continue to attack him, you will be blocked (not by him, but by another administrator), as he is not discriminating against you at all. Kevin Rutherford (talk) 21:33, 27 May 2013 (UTC)
Furthermore, he is going by a guideline that says that no personal websites can be used, which is designed to prevent information that could potentially be incorrect. Since you do appear to be very knowledgeable about this issue, I would encourage you to see if you can find a substitute on another site or move your material onto your school's page, because our hands are really tied on inclusion if it doesn't follow the guidelines. If you need help with this, I will help to lend a hand. Kevin Rutherford (talk) 21:40, 27 May 2013 (UTC)
Thank you Kevin, May God Bless you. Thank you for your suggestion. I will move all the tutorials to my university page. I prepare those tutorials to share my knowledge with the world, and the wikipedia is a great place for this purpose. And, I hope the other editor starts to do research before s/he deletes anything, or at least he proposes a solution instead of dictating his/her idea without providing any scientific reasoning. — Preceding unsigned comment added by (talk) 21:58, 27 May 2013 (UTC)
Note that moving the pages to your university website and then continue spamming them as external links, will not help. Again (for the 4th time), see wp:NOR, wp:COI, wp:ELNO item 11. Nothing will change that. DVdm (talk) 06:25, 28 May 2013 (UTC)

Dear Mr. DVdm Please accept my apologise, maybe I was not clear enough. I just want to reconfirm that information given, here below copied, is genuine and reliable. " On October 9, 2012, before his solo concert in Amsterdam, he was delivered by the Italian Fan Club a Paoletti Custom guitar model "Wine Stratospheric" especially designed for him by the famous Italian luthier Fabrizio Paoletti owner of the homonymous Paoletti ® instruments" You can check it personally on this YouTube link: Also, if was the link to Paoletti Guitars website that caused problems, we can remove it, no issue. Please let me know if and how to proceed. Once again, we apologise for any inconvenience. — Preceding unsigned comment added by (talk) 10:19, 31 May 2013 (UTC)

Yes, but first, Youtube is not considered to be a very wp:reliable source (in the Wikipedia sense), and I also think that this particular information is not relevant to the article. In the spirit of wp:BRD I suggest you open a little section on the Sambora article talk page and propose to add the content. I don't think it will be accepted, as some might see it as a Paoletti Guitars advertisement, but good luck anyway. Cheers - DVdm (talk) 10:50, 31 May 2013 (UTC)

Quartic equation


This is an answer to your last post in Talk:Quartic function.

1/ I have sourced the general formula as derived by a simple calculation from another formula in the page. It remains to properly sourcing this section (and the other ones), which is not difficult. I have verified that this derivation is correct, but this verification would be much easier if the notation would be uniformed through all the page. But it is better to wait on more stability before doing that. IMO, it is not a good idea to use the formula in the French-Chinese thesis, because the latter is intended for a purely real computation, which complicates the formula and could be confusing for the readers. By the way, I was not aware of the content of this thesis although it was defended in my lab and I was the supervisor of the French supervisor of this thesis, and also reviewer of the habilitation thesis of the other supervisor.

2/ Nature of the roots. I have expanded this section partly because of a recurrent wrong edit by some editor, partly because it could be frustrating for the reader to have an incomplete classification. The classification provided in the above thesis, is directly derived from the general methods working for every degree and do not take into account the fact that the degree four may be (and is) simpler. Therefore, I am against to use it there. On the other hand, I am able to source the classification I have provided only for the case of 4 complex roots. However it is a rather simple exercise to deduce the complete classification from this old paper of myself. Thus this classification is essentially WP:OR. But we have to choose between this and an incomplete or unnecessarily complicated classification. IMO, this is a case where WP:IAR applies.

D.Lazard (talk) 14:55, 1 June 2013 (UTC)

Persia, Iran, Iraq

With respect to this edit, you just may be interested to know that Persia is part of Iran, and never was Iraq. JamesBWatson (talk) 10:13, 5 June 2013 (UTC)

Watch article

Yesterday, somebody edited out part of a sentence, for no apparent reason, leaving something that was ungrammatical and senseless. I put it back, almost but not quite to the way it was. Now I see that you have deleted my wording, restoring the lack of good grammar and sense, on the grounds that it was "unsourced".


Just take a look at the images of watches on that page. Most of those with analog displays are set to the times of 10:10 or 1:50. Everyone knows that watches are usually sold with their hands at those two times. That's all I said.

If you refuse to include this piece of common knowledge, then at least fix the grammar.

DOwenWilliams (talk) 02:16, 6 June 2013 (UTC)

Yes, you are correct. I should have looked closer. I have undone the evil now ([5]), but I have left out the 1:50 remark, as it is not mentioned in the sources. My apologies. - DVdm (talk) 06:26, 6 June 2013 (UTC)
Apology gladly accepted. However, I have put the 1:50 back in, and taken the 10:09 out. In reality, the times to which watches (and clocks) are set vary by several minutes either way, so there's no point in our trying to be accurate. However, settings around 1:50 are just about as common as those about 10:10. I guess whoever wrote the sources didn't think about it much.
(The image close to the text we are discussing shows a watch set to about 1:54.)
I'm a well-known sceptic about sources. See my user page (not the talk page).
DOwenWilliams (talk) 14:50, 6 June 2013 (UTC)
No problem. Who cares anyway? Apart from us, that is :-) - Cheers - DVdm (talk) 15:37, 6 June 2013 (UTC)

Probably, nobody cares.

Do you mind if I ask you a related question? There's an article about someone I used to know, long ago. I stumbled across it, and found that it was pure BS. I did some editing, so it resembles reality, but it was purely from memory, since there's nothing available to cite. (There was already one citation, quoting someone who was lying!) Very few people read the article, so I wasn't worried. But it turned out that the person it is about did read it! She tracked me down a few days ago (we had been out of touch for decades), and e-mailed me. She was quite happy with the article (said it was "astonishingly accurate"), but thought it could do with some extra details. She asked me if there were any rules about biographical articles being edited by the people they are about. I said I didn't know, and suggested she should try it and see what happens. So far, she hasn't made any changes.

What do you think?

DOwenWilliams (talk) 20:44, 6 June 2013 (UTC)

If nobody challenges the content, there is no problem. Otherwise, see wp:BURDEN specially for wp:BLP.

Sources, sources, and more sources. Sceptics about sources tend to get in trouble here, specially the well-known ones, so be careful. Cheers and good luck. - DVdm (talk) 09:24, 7 June 2013 (UTC)

I noticed that you've got a couple of quotations of Frank Zappa above. So maybe you'd like to know that the woman I used to know, and mentioned above, was Suzy Creamcheese. DOwenWilliams (talk) 04:02, 11 June 2013 (UTC)

Now that's interesting! What's also pretty interesting, is that she has an article in here. I hadn't seen it before. In order to improve it, I have put a few tags on it ([6]). Looks like you have some work ahead. Happy source hunting and thanks for letting me know. - DVdm (talk) 07:22, 11 June 2013 (UTC)

No. Sorry. I have a life to lead. I'm not going to waste it chasing sources for an article that almost nobody reads. I fixed it up to make it factually accurate, relying on my own memories of events long ago. (I was sitting next to Suzy in the Albert Hall when she had that exchange with Zappa.) But, if you want to try to find sources, good luck! DOwenWilliams (talk) 15:35, 11 June 2013 (UTC)

I'll see if I can find something. Otherwise I'll give it a few weeks for others (and/or for you) to find some sources. After that I'll probably remove it. Cheers! - DVdm (talk) 15:39, 11 June 2013 (UTC)

Be cautious about what you accept. I did mention that there is a citation of someone who was not being entirely truthful. I gather that Suzy and Zappa were not on good terms when she left the group, and Zappa "spun" the history of the Mothers to make it appear that there never had been a real Suzy. The citation is of a radio interview in which he said as much. You may well find similar distortions. DOwenWilliams (talk) 15:49, 11 June 2013 (UTC)

On further thought, maybe you should just add a tag that says that the factual accuracy of the article is in doubt. I think there's a tag for that. I think it's highly unlikely that you will find really reliable sources to cite. On the other hand, simply deleting the article would be, I think, a shame. This little piece of history deserves to be documented somewhere.

Check the Talk page. Several people have referred to other people with the same nickname.

I still know three or four people, besides Suzy herself, who remember those events. But we can't cite their memories.

DOwenWilliams (talk) 21:34, 11 June 2013 (UTC)

No worries, I'm not going to nominate the article for deletion. I'll just remove your recent unsourced additions, perhaps. We'll see what turns up. Cheers, and say hello to Suzie :-) - DVdm (talk) 06:47, 12 June 2013 (UTC)

If you put the article back to the way it was before my recent edits, you will restore its total falsity. It never had any worthwhile sources. I'm not sure what the original author used, but it certainly wasn't what Wikipedia would regard as a citeable source.

My e-mail address is on my user page. Send me an e-mail, and I'll tell you some stuff that I don't want to post publicly.

DOwenWilliams (talk) 14:51, 12 June 2013 (UTC)

Whatever you write in an email to me is entirely irrelevant for Wikipedia, so don't bother. But thanks for the offer anyway. Cheers - DVdm (talk) 15:13, 12 June 2013 (UTC)

Electronic Arts - Electronic Arts Limited the original NAMED company in the UK

Thanks for asking for Citation re: Electronic Arts

The info I posted regarding electronic arts is matter a fact I worked there from 1984-86, it was one of the first full 3d Computer animation studios in the UK. The company was originally founded by the ex director of BBC Dr Who as a effects company, which pioneered 3D animation in the UK.

The company worked from premises in Chalk Farm, Primrose Hill, before moving to the City of London, where in 1987 it changed its name to Amazing Array Productions, as EA brought the name/ registered it in the UK.

I am trying to collaborate dates, but think it would be GREAT to get the facts right:::

I can cross reference, key individuals -

namely:: Jilly Knight:: Head of Animation::

Phil Mitchell ;; Animator and Founder of MAINFRAME Animation in Canada, Creator of ReBoot

You will NOTE that Phil uses the pun = we where not the GAMES Company!!!! and thats what we have had to say for the past 28 years as the name was brought up by EA

hope this helps, I am trying to construct a timeline and will forward this on to you, as we where Pinoneers in the UK.

Ok. The information could be interesting and perhaps even fit to be included in the body of the article, provided of course a good wp:reliable source (from e.g. a text book, or from a technical article) would be available to back it up. The information on that company site probably orginates from such a source, but of course we cannot use that site. Cheers - DVdm (talk) 13:55, 13 June 2013 (UTC)

What you see is not constructive? It violates several rules of Wikipedia. I told him this many times. However, he does not care. He ignores sources and arranges the war edits. It even changes the quote from the source.--Lori-m (talk) 14:32, 19 June 2013 (UTC)

I noticed that your edit consisted of the text "You lie and do not blush!", which did not sound constructive to me. Perhaps I should have issued a warning for personal attacks. Next time, I promise. Let's try to remain civil and wp:AGF. Cheers - DVdm (talk) 14:40, 19 June 2013 (UTC)
Thank you very much that explained. I get it. I will correct. Do you mind if I write "обманывать не хорошо" (spoof is not good)?. If I write something on the Russian'm sure he will understand.--Lori-m (talk) 14:51, 19 June 2013 (UTC)
It would still be sort of an accusation of spoofing or cheating. Best to keep it as neutral as possible, and best to write English only here. Cheers - DVdm (talk) 15:12, 19 June 2013 (UTC)
According to Russian would be easier to explain it to him. He is trying to deceive readers. I can not affect it. In the article I quoted from the source. It is written: "Matzoon or mazun, originating in Armenia". However Obitauri changes "Armenian" on the "Georgian", and "Matzoon" on "Matconi". Tell me where I can complain about him? P.S. Forgive me for my english--Lori-m (talk) 15:36, 19 June 2013 (UTC)
First, you must stop reverting each other. I have put warnings on both your talk pages for edit warring. The warning has some links to interesting articles that explain what to do in such cases. Note that after this warning one of you reverts again, I will report at WP:AN3, which probably will result in a block, perhaps even of you both. So try to reach consensus on the talk page, and above all, stick to facts and remain civil. - DVdm (talk) 15:52, 19 June 2013 (UTC)
Ok. Do you mind if I call you for advice?--Lori-m (talk) 15:57, 19 June 2013 (UTC)
I don't mind, but I will not be able to give advice about the content. I know nothing about it, or about the languages involved, or about the countries or states, or about the politics. - DVdm (talk) 16:02, 19 June 2013 (UTC)
Thanks. Nothing complicated. We must adhere to the rules of Wikipedia. And when there is a dispute, we have to literally refer to authoritative sources. I always try to do that. Thanks again for your help :)--Lori-m (talk) 16:33, 19 June 2013 (UTC)

war with 8i347g8gl on Mass–energy equivalence

You and 8i347g8gl need to stop reverting one another on Mass–energy equivalence and first discuss it on its talk page! I'm posting the same to 8i347g8gl.DavRosen (talk) 16:27, 19 June 2013 (UTC)

Oh, I see 8i347g8gl got blocked. I think the biggest problem with what he did was removal of the other content, since he did eventually add sources for the content he added. DavRosen (talk) 16:50, 19 June 2013 (UTC)

See this edit. The first part of the edit was utterly inadequately sourced (Astronomy Quiz Book). The second part (see near the bottom of the diff) was not sourced at all. See the specific reason for the block. - DVdm (talk) 17:16, 19 June 2013 (UTC)

please read Mass–energy equivalence talk page and discuss, esp my entries re "convert matter to energy"

Note that SBHarris has agreed in principle that the "convert matter to energy" terminology needs to be changed. I haven't made any changes yet because I'm first discussing so I don't get reverted. DavRosen (talk) 16:58, 19 June 2013 (UTC)

Yes, I had seen that. Carry on, but try not to fringe the article, and use sources which are slightly more relevant than some Quiz Book :-) Cheers - DVdm (talk) 17:23, 19 June 2013 (UTC)
Mostly I'm thinking to begin changing some of the eclectic (and unsourced) statements about mass vs matter [non-]conservation into something that relies more on the better-defined concepts (like rest mass) that are already explained elsewhere in the article and are themselves properly sourced there. BTW, I looked at the versions of this article in about ten other languages, and none appeared to have anything resembling the statements about matter that we see in this article. For the term "matter" itself, perhaps we need to rely more on the article by that name; it isn't very good if I recall, but that needs to be improved in that article. Of course I'll source anything new/nontrivial/controversial or that doesn't follow directly from the existing parts of the article. Or at least this is my understanding of how to do things -- I'm new to editing articles :-) DavRosen (talk) 18:53, 19 June 2013 (UTC)
Your best bet would be to stick to the article talk page. If there is no reaction to your proposal(s), then by all means, be wp:BOLD, go ahead and make the edits to the article, making sure you mention the talk page in your edit summaries. Good luck! - DVdm (talk) 20:32, 19 June 2013 (UTC)


You just warned me, yes I got your warning and understood but I just fixed this article, What was wrong? I just put new sources and didnt undone anything? I just edited article with new sources. This gives you reason to report me? --Obitauri (talk) 21:04, 19 June 2013 (UTC)

I talk about edits after you warned me. This edits are not breaking rules. I just wanted to fix conflict and see talk what I say: "Darra Goldstein. The Georgian Feast: The Vibrant Culture and Savory Food of the Republic of Georgia. University of California Press, 1999, p. 51

This totally shows its Georgian. "University of California Press", this is one of most reliable sources. We need to discuss both sources, which says Armenian and other which says Georgian as of this article became battlefield of editing... We need to check both sources... But before we must not say anything about origin in article cause we found 2 sources one says other, 2nd other thing we need to remove origin from article --Obitauri (talk) 18:57, 19 June 2013 (UTC) --Obitauri (talk) 18:57, 19 June 2013 (UTC)"

Then I edited article and removed origin of this product cause its discussing right now, I shown Lori-m source he removed it before this edit warring. He removed several resources from this article which said it was Georgian just see history. I just wanted to fix this and did some mistakes in editing (such as changing sources). I fixed them now and just put new source. Here is problem which needs to be discussed: 1 source says that its Georgian, other says its Armenian. We need to find out which is true and if we cant, jsut leave like not writing origin like article looks like now. Do you understand me now? What did you gave reason of reporting me? --Obitauri (talk) 21:14, 19 June 2013 (UTC)

Commented here. - DVdm (talk) 06:27, 20 June 2013 (UTC)


Hi, we recently crossed paths at User talk:Cjohnson20001. (I was trying to revert their edits to the Afterlife article, but you beat me to the punch...twice.) Anyway, I appreciate the work you're doing, but it rubbed me wrong when you gave them a level 4 vandalism template for this edit. Yes, it was POV, edit warring, using Wikipedia as a platform, etc., but it seems to have been in good faith, and I would hesitate to call it vandalism. Anyway, I guess I just wanted to suggest that you take a softer approach when dealing with new and inexperienced editors. ~Adjwilley (talk) 06:01, 22 June 2013 (UTC)

Yes, I seem to have hit the wrong button. Note however that after another unsourced addition the result would have been the same: they would have been reported at the vandalism noticeboard. It's what Huggle does after a 4th level warning when reverting again for addition of unsourced content. See my remark and admin Nyttend's reply at :

When such edits are always unsourced, they can be removed per wp:unsourced, accompanied by a user warning. When the user refuses to react to the warnings, one similar edit after the final warning is usually considered to be vandalism, and as such reported by wp:Huggle at AIV. - DVdm (talk) 19:03, 4 June 2013 (UTC)
Agreed; this is precisely why {{uw-unsor4}} says that people may be blocked for further violations. Any admin who blocks you for a 3RR violation when you're removing this kind of thing from the article would deserve a pile of trouts — this is the kind of graffiti that doesn't belong in an encyclopedia article. Nyttend (talk) 23:43, 4 June 2013 (UTC)

But indeed, I should have used the appropriate option, which would have resulted in the final {{uw-unsor4}} warning. Cheers and thanks for letting me know! - DVdm (talk) 07:23, 22 June 2013 (UTC)

Yes, I noticed. But on so-called wp:disambiguation pages such as NBD normally only references to existing articles (or perhaps to articles immediately to be created) are to made. Cheers - DVdm (talk) 15:33, 24 June 2013 (UTC)

I'm not sure I'm doing this talk thing right... but I see you recently warned the guy that edited Machairodus

I only came to notice this, because I was on the cynodont page, and saw that permian had been changed to paleocene.

Is there any way to find out any other edits this guy did? it seems he went active on the 25th of june, and perhaps there is some damage he's done that hasn't been fixed yet.

You're doing fine, but I have moved your text to the bottom, added a subject line, and moved the link with the difference (diff) just above your signature. Hope you don't mind :-)
Yes, there is a very simple way to do it by going to the so-called diff and merely clicking the user's IP-address in the heading on the right side, immediately under the line 'Revision as of 20:53, 25 June 2013 (edit) (undo). When you click the IP-address, you get the user's contributions, like here. That's how simple it is. When you go to their talk page, you'll also see the other known IP-addresses (with links to contribs) they have been using for the same kind of vandalism.
Note that you can keep a monitoring eye on various articles by putting them on a so-called watchlist. You need to get a username for that. Anywhere you go and logon to Wikipedia, you get the same settings, watchlist, user page and talk page, and you're still anonymous. Read all about this at Wikipedia:Why create an account? and Wikipedia:User access levels#User groups.
I also have left a welcome message with some handy pointers on your IP-talk page. If you have any questions, as away! - DVdm (talk) 15:41, 26 June 2013 (UTC)


I am writing to you because I want to avoid an edit war. I thought you could intercede. Earlier today Mrm7171 made a wholesale deletion from the Wikipedia entry on Industrial and Organizational Psychology. The deletion was is not justified. The deletion was of a short paragraph on the relation of i/o psychology to OHP, a paragraph that I restored. The paragraph is justified in that OHP emerged out of i/o, health psychology, and occupational health. Each of the encyclopedia entries for those three disciplines has contained a short paragraph on the discipline's relation to OHP.Iss246 (talk) 18:50, 5 July 2013 (UTC)

Hi Iss246. I have been away for a few days. It looks like the problem took care of itself by now — at least for a while.

Hi DVdm. I didn't understand why you thought changing to was factually incorrect. It is implied directly from the equations that follow in that section. Thanks. — Preceding unsigned comment added by Anant.sogani (talkcontribs) 21:41, 5 August 2013 (UTC)

Your expression is ambiguous and thus not properly formed and indeed other than through context there is no way to decide whether the exponent works on the log or on its argument. In mathematics let's not rely on context to allow such ambiguous expressions. But I agree that I my templated warning on your talk page was a bit off the mark. Feel free to remove it altogether. Cheers - DVdm (talk) 07:30, 6 August 2013 (UTC)
Agree. I had not put the extra parentheses after correcting the expression since I thought it was redundant. But with what you said, and after looking around for similar notation elsewhere, I realize I was wrong. Thanks. :) - Anant.sogani (talk) 10:46, 6 August 2013 (UTC)

Regarding validation of the Twin Paradox

Hi Dvdm

You are right, it was not reliably sourced, according to wikipedia definition. It was true, though, and there was a source reference to a comprehensive, logical treatment. I was almost certain that wikipedia would be inconducive to new truths, but I needed to try it out, in order to determine the exact nature of the obstacle. This is, of course, not a criticism of your removal of my contribution, as another would have done so in your place, given that the regard of 'reliable sources' is a fundamental requirement for wikipedia articles.

Makes you wonder whether wikipedia may not result in truth stagnation, though, however wonderful a site it otherwise is. In this case, my contribution employed correct logic, which does not require any authority's acknowledgement to those able to follow it. But wikipedia, then, will have to wait for such acknowledgement.

Aquarius Philosophicus (talk) 16:01, 11 August 2013 (UTC)

Yes, Wikipedia will have to wait for such views to have become part of the mainstream view. I doubt that it will, as in your edit I found three major mistakes, two of which you seem to use as premises for your logical argument. As you probably know, correct logic on false premises tends to produce useless conclusions. That is of course the reason why Wikipedia strictly requires wp:reliable sources and even more strictly forbids wp:original research. You probably can imagine what this place would look like without such policies ;-) — Cheers - DVdm (talk) 20:55, 11 August 2013 (UTC)

So basically you say that an outright lie should remain posted on Wilipedia while I attempt sine die to discuss the matter with the very same editor who posted that outright lie (and who did it fully knowing that this is an outright lie)? All this in spite of the fact that I provided 5 solid references to prove that the content added by me is correct, accurate and complete? When did the truth ceased to matter? Optimvs (talk) 20:20, 3 September 2013 (UTC)

No. Basicly I say that controversial edits should be discussed on talk page and that edit warring will get you nowhere. - DVdm (talk) 20:22, 3 September 2013 (UTC)
Yup, the problem being that you said that while reverting to the outright lie, hence my question. Which still stands. I don't understand, is your goal to hide behind technicalities while an obvious and proven lie stays on wikipedia? The edit history clearly shows that the other part has no intention whatsoever to discuss or to act in a constructive manner. This is proven by the countless reverts done by IP's today. Optimvs (talk) 20:27, 3 September 2013 (UTC)
I'm not even remotely interested in what you are trying to add, and I haven't even looked at it. I try to help you understand that edit warring will get you nowhere. If you care about the truth, then go to the talk page and discuss. Good luck. - DVdm (talk) 20:31, 3 September 2013 (UTC)
I was trying to make you understand that what you actually did is help people who are trying very hard (see the IP reverts trough this day) to keep a lie posted on Wikipedia. Why not stay out of the whole thing if you are not willing to actually READ the disputed material (which wasn't that long)? When you see an edit war in which IP's keep reverting a page 20 times or so during a single day what do you do, make the same revert as they did? Jeez... Optimvs (talk)
It looks like you have been blocked for edit warring — as I predicted. Do have a very close look at and read of wp:SYNTH, wp:NPOV, and most of all, at wp:CONSENSUS. Good luck. - DVdm (talk) 10:07, 4 September 2013 (UTC)

Inertial Frame of Reference

Hello. I notice that you keep adding the the line "However, the general theory reduces to the special theory over sufficiently small regions of spacetime, where curvature effects become less important and the earlier inertial frame arguments can come back into play."

This is fundamentally not correct, as it implies that small regions of spacetime have negligible curvature. This is NOT AT ALL the criteria for curvature effects vanishing. Rather, it must be in the neighbourhood of a point in the manifold in which the Christoffel symbols and their partial derivatives vanish. This is the only way that curvature drops out to zero and one has flat spacetime. The two sources you cite are not credible sources for this topic, rather, any standard textbook on differential geometry will tell you this.

You CANNOT construct a Minkowski coordinate system in an open neighbourhood of a general point in a curved spacetime, since there may be cross-terms that do not vanish. A prime example is the Kerr metric, where you simply CANNOT construct Minkowski coordinates in the neighbourhood of a point, for the simple reason that the cross-term (say in t and phi) cannot be eliminated, since the differential rotation of the vacuum is real, and cannot be transformed away. Of course you can introduce Minkowski coordinates in the TANGENT space, because it is by definition flat.

You really have to make these points clear. They seem subtle, but are very much at the heart of the topic in question.

Thanks for your quick action.

Is this possible to rename article page? The article M. A. G. Osmani refers to a great national personality of Bangladesh. So the page should contain the full name of him e.g. Muhammad Ataul Gani Osmani.

Sure, that is possible, but you'll have to propose that on the article talk page Talk:M. A. G. Osmani to find out what the other contributors think.

Cancelled edits in the List of people by Erdős number

You asked for references regarding people with small Erdős number, which I am providing below.

According to [DBLP|], Paolo Codenotti (and a number of other people) co-authored papers with László Babai, who is listed as having Erdős number 1. Therefore, Codenotti and others should be listed as having Erdős number 2.

According to [DBLP|], Igor Markov (and a number of other people) co-authored papers with John P. Hayes, who is listed as having Erdős number 2. Therefore, Markov and others should be listed with Erdős number 3.

According to [DBLP|], Yaoyun Shi co-authored papers with Andrew Yao, who is listed as having Erdős number 2. Therefore, Shi should be listed as having Erdős number 3.

The current list is probably missing hundreds of people. — Preceding unsigned comment added by (talk) 04:22, 20 September 2013 (UTC)

Did you see the link? Did you hear what he said (and in the l;ast 2 session of the UNGA). Wildly accusing Russia of being wrondg in everythiong and criticiseing all of its history (laughable since hes from the land of Stalin) is Russophobia. What else defines Russophobia then? (and the article would need a concrete definition.(Lihaas (talk) 14:19, 28 September 2013 (UTC)).

Indian and Pakistani celebrities

Hello DVdm, thanks for you help on the Fawad Afzal Khan article. In case you aren't familiar with what's going on with these celebrity articles let me fill you in on some of it. First, I know nothing about any of these people or the entertainment industries of India and Pakistan. As happens I got sucked into these articles following a vandal and discovered tons and tons of problems. Recently the one I've been focused on is where a dynamic IP keeps adding to articles that person X is Muslim and "born into a Muslim family". Every once in a while a source is supplied (hard to tell if these are reliable sources but that's another issue) but the vast majority of time one isn't. Along with that edit are all sorts of other OK looking edits about the person's career. Generally unsourced but also uncontroversial. What I mainly do is revert the unsourced religious claims since I don't want to take the time to assess the quality of the rest of their edit.

Anyway, it's an ongoing problem and any help in dealing with it is greatly appreciated. SQGibbon (talk) 14:53, 27 September 2013 (UTC)

I probably won't keep this page on my watchlist for long, but when I see an unsourced addition, I will probably revert. Thanks and cheers. - DVdm (talk) 15:10, 27 September 2013 (UTC)
Note - In the spirit of wp:DGAF I have removed the page from my watchlist. - DVdm (talk) 09:32, 30 September 2013 (UTC)

Removal of content at Talk:Length contraction

Regarding your removal of content at Talk:Length contraction: I had recommended to the user who added that content (LCcritic (talk · contribs)) that they open a discussion on the talk page after I had removed their edit to the page itself. The user appears to wish to broaden the scope of the article by including a discussion of the controversy discussed in the material you removed. I don't believe it was this user's wish to open a general chat, but rather to introduce material for discussion prior to introduction to the article. I would like to see the material restored to the talk page so a proper discussion can take place, but I don't wish to step on any toes. I'm not a physicist and will readily claim little understanding of the topic at hand. I also admit that I believe LCcritic is trying to introduce something of a fringe theory, but I thought a proper discussion rather than a dismissal out of hand was in order. WikiDan61ChatMe!ReadMe!! 18:19, 9 October 2013 (UTC)

Hi WikiDan, I just checked LCcritic's message on your talk page. The phrase "I've studied the debate on length contraction for some 18 years now" and the user's username choice make me pessimistic — we've seen this before. Regarding the recommendation that you made, I would advise against restoring the talk page comment, but if you would do it, I wouldn't step on your toes. Cheers - DVdm (talk) 18:34, 9 October 2013 (UTC)
I'll defer to you on this. As I said, I'm no expert on physics of any sort, and am not aware of the history of this debate. I thought it was probably pseudoscientific quackery, but I wanted to be sure. WikiDan61ChatMe!ReadMe!! 18:37, 9 October 2013 (UTC)

Wikipedia is of course not a place to share freeware tools. There's a lot of things that Wikipedia is not — see wp:NOT. Perhaps you can open a little section on the article talk page and ask whether other contributors would mind your "advertising" these own written tools. Of course, if/when you see other inappropriate external links, feel free to remove them per wp:ELNO. Your best best: the article talk page(s). Good luck and ditto software writing.

Perhaps the other contributors judged these links as appropriate. Again, open a little section on the talk page and discuss with the others. Wikipedia is mainly about wp:consensus. Try it, it's fun. - DVdm (talk) 19:33, 9 October 2013 (UTC)

I am very lame navigating

DVdm, I am very lame at navigating here, so when I couldn't find my "talk" comments, I thought you had deleted them. Sorry. Just now, replied to your last response to me and then could not find it. (Just my unfamiliarity with the site, I am sure.) Anyway here it is again, and it it is a duplicate, please bear with me as I learn the ropes here. Thanks. You said: "Nowadays (i.e. since a century or so), "physical" and "real" (and even "geometrically") all mean "operationally and reproducibly measurable". Anything beyond that seems to have become what we could call arm-chair philosophy, i.e. wasting one's time on the usage of words. Just like velocity and energy, length is a coordinate dependent property. That does not make it "unphysical" or "unreal" or "merely geometrical". -"

This ignores the present length contraction debate (as in all science forums with a relativity section... before LC critics are banned) on whether LC is a physical phenomenon or not, which is a legitimate question for science. I have given examples of both sides as found in Wiki, and it can not be both ways, so the issue begs for disambiguation. You say, "length is a coordinate dependent property," as if the debate is settled and physical objects have no intrinsic, objective shape, length or distance between them, and it all depends on how you look at them (frame of reference.) It is not just arm-chair philosophy to declare that a contracted Earth diameter (say 4000 miles as "measured" from a frame approaching at .866c as in my example) is not "equally valid" with the its proper diameter length, measured in Earth's frame, just under 8000 miles.

The same applies to the often referenced barn and ladder/pole paradox. A 20 foot ladder will not fit into a 10 foot barn, regardless of different relativistic frames of reference. These are physical objects. A force must be applied to compact them to shorter length, and special relativity does not include such force in its theory. It just claims that varying measurements indicate varying lengths, and this must be generalized to all objects, like Earth, which clearly does not vary in diameter length with all possible relativistic frames from which it might (someday, theoretically) be measured. LCcritic (talk) 17:00, 12 October 2013 (UTC)

I prefer to use article talk pages for discussing articles, and user talk pages for discussing user conduct. What you write here is about your opinions on the subject of some article, and therefore off-topic. If you want to discuss the format and the content of the Length contraction article, you should confine yourself to the article talk page Talk:Length contraction. Do make sure that, with every word you write, you discuss the format and content of the article, not the subject or your personal opinions about it. Good luck. - DVdm (talk) 17:32, 12 October 2013 (UTC)

Please read the talk pages of Bengali novels, Bangla rock and Bengali science fiction. You will know who is doing vandalism

Please read the talk pages of Bengali novels, Bangla rock and Bengali science fiction. These articles have huge amount of material on Bangladesh but very less on West Bengal. The article on Bangla rock has been redirected to Bangladeshi rock, a term which does not even exist! This is pure vandalism. If you see the History of these three articles to 2 or 3 years back, say the page as it appeared on 16 October 2010 or 2011, you find an unbiased article. If you are an administrator, please do something. I was forced to add the vandalism tag to the mentioned articles.

And I am not the only person who feels that the above mentioned articles are biased towards Bangladesh while ignoring West Bengal. If you read their talk pages, you can get others' views. I am not making unconstructive edits to Wikipedia as you just wrote on my talk page. I have been sharing whatever little I know with Wikipedia as an anonymous user since last 2 years and as a registered user since <1month.

Still I think that adding the {{tn:vandalism}} tag to these articles is inappropriate. Good luck with your politics. DVdm (talk) 20:32, 15 October 2013 (UTC)
This was not politics from my side. I was trying to rectify some pages. By adding the vandalism tag, I tried to bring the attention to the actual vandalism going on in those pages. And by the way, if I am to do politics, I can leave Wikipedia and start writing a blog. That way, I can do politics as well as earn some money for extending my political activities. I can make some page on Facebook and do politics. Why to join a free group like Wikipedia? As I have told you, I am not the only one who sees fault with the mentioned articles. If you read their talk pages, you can read others' comments also. I may have done mistake by adding vandalism tag to the articles, but if you see my approach as "politics", its painful. Thank you.

Its not vandalism if you dont like it

Hello, With regard to the definition of reliable and unbiased source for Fasih Mahmood, I have included the source as twocircles website which primarily deals with isses related to indian muslims accused of terrorist charges and under judicial custody. their website is Yet time and again I am being told this is not a reliable source. Why? I read the definition of reliable and unbiased source and it completley fits the bill. The onus is on you to disprove it. If you can't then let my edit stay in place. I have the feeling I am being harassed for vandalism. When however it is exactly the opposite of what I am trying to do.

I do not have the time or effort to continue this circus. If people are genuinely interested in knowing more about Fasih Mahmood they can check out the articles at and decide for themselves.

Insofar as the formating of the article is concerned I accept my mistake. I am new to wikipedia and therefore not a pro on editing and formating.

However if you read Neelkamala's comments on my edits, the formating is not the issue. The comments focus on and question the reliability of the source. When in fact a simple proofreading of the article in its current state will show how "Fasih Mahmood has a bachelor of arts" and then "He is an engineer by training". If you are aware of education in India. one doesnot become an engineer by training after obtaining a BA. These are contradictory statements which I resolved to rectify. — Preceding unsigned comment added by (talk) 06:10, 21 October 2013 (UTC)

Jewish by birth

As a result, mere belief in the principles of Judaism does not make one a Jew. Similarly, non-adherence by a Jew to the 613 Mitzvot, or even formal conversion to another religion, does not make one lose one's Jewish status. Thus the immediate descendants of all female Jews (even apostates) are still considered to be Jews, as are those of all their female descendants. Even those descendants who are not aware they are Jews, or practice a religion other than Judaism, are defined by this perspective as Jews, as long as they come from an unbroken female line of descent. As a corollary, the children of a Jewish father and a non-Jewish mother are not considered to be Jews by halakha unless they formally convert according to halakha, even if raised fully observant in the mitzvot.[1]

Schizophrenic number

Hello DVdm, I am new to editing WikiPedia, but since I found the page about 'Schizophrenic numbers' to be called an 'orphan page', I thought I'd correct that. If you think that is not useful, then by all means leave it as it is, because I'm not going to haggle over whether the link is useful. In that case it is better to just agree to disagree, and both continue what we love to do most.... ;-)

Namaste, André — Preceding unsigned comment added by Moorelife (talkcontribs) 19:24, 1 November 2013 (UTC)

Regarding the removal of my edits from the "Time" article

Hi DVdm,

First off, thanks for sending a personal talk page message that clarifies your issues with my edits.

I do agree that my sources do not qualify as reliable sources by wiki standards; however, I think they are more than adequate given the claims made within my edits. The "identifying reliable sources" wiki page states that "A lightweight source may sometimes be acceptable for a lightweight claim, but never for an extraordinary claim." Since I view my edits as containing "lightweight" claims (i.e., claims that are intuitively credible to any intellect), I believe its fine. I certainly would search extensively for "said" reliable sources if I had more time availability and if it was less time-consuming. Please let me know on my talk page how you now feel about my edits, and if your opinion is unchanged, could you please specify the types of sources you would consider reliable (i'll also check out the wiki page for reliable sources that you sent b4).

Best, Jon — Preceding unsigned comment added by Jwratner1 (talkcontribs) 03:09, 7 November 2013 (UTC)

Hello. I saw you tagged a page for deletion called "The Cosmos Leader". May I ask was it something to do with me because I recently warned him and deleted his page for vandalism. --The Cosmos Master (talk) 19:55, 10 November 2013 (UTC)

Hi, I don't recall the content of the page, but it was clearly vandalism. I have no idea whether it had something to do with you. Seems likely though. Article is deleted now and user indef blocked. - DVdm (talk) 20:13, 10 November 2013 (UTC)

Regarding the removal of my External Links

Hey DVdm, is legit lyrics site that is powered by LyricFind. Recently, the legit lyrics site MetroLyircs got an approval from Wikipedia to submit their own links as external links by bot. We, too, are working on that approval - by bot. As long as MetroLyrics are posting their links and in a legit way, so should we. We are licensed publishers and our data is no spam whatsoever. please do not remove our links anymore. Thanks so much. Lilamay2013Lilamey2013 (talk) 09:56, 10 November 2013 (UTC)

See this. - DVdm (talk) 10:09, 10 November 2013 (UTC)
And this. - DVdm (talk) 10:58, 10 November 2013 (UTC)

Dear friend, on Rehevkor's talk, and also on the spam page, you declare that Qtrax is now using a bot. This is an incorrect claim. MetroLyrics, owned by CBS Interactive is a commercial website that uses a bot for external links. Qtrax only added links manually. Never with a bot (yet). Please reconsider your claims, which tends to make other editors think that Qtrax is a spam or pirate service. Qtrax is the only service in the world that has license to distribute LEGAL music for FREE. Yes, music that is licensed by record labels (meaning we do pay the artist every time our users listen or download the artist's song), but provide it 100% for users.

Furthermore, in my opinion, placing and external link on a Wikipedia page of a notable song, that redirect to an official and licensed page, is quite a great service both to Wikipedia's readers, and musicians. Both enjoy.

I beg you to be precise in your claims. Much thanks in advance. — Preceding unsigned comment added by (talkcontribs) 14:22, 13 November 2013 (UTC)

Huggle 3

Hey DVdm! I am Petrb, one of core developers of Huggle, the antivandalism tool, which you are beta testing (according to I am happy to announce that Huggle 3 is ready for some testing. You can read more about it at WP:Huggle/Huggle3_Beta. Please keep in mind that this is a development version and it is not ready for regular use. That means you must:

  • Watch your contribs - when anything happens you didn't want, fix it and report a bug
  • Frequently checkout source code and build latest version, we change it a lot

If you find any problem with a feature that is supposed to work perfectly, please let us know. Some features are not ready yet, it is listed in known problems on Huggle3 beta page, you don't need to report these - we know it! So, that's it. Have fun testing and please let us know about any problems, either using bugzilla @ or #huggle connect. Please respond to my talk page, I am not going to watch your talk page. Thank you Petrb (talk) 10:57, 14 November 2013 (UTC)

Replacement link on Bernoulli Principle web page

Hello, I believe there are two issues here: 1) I updated a stale link on the Bernoulli Principle page ( 2) I added new links on other pages

Here are the reasons I think the Bernoulli link should stay: 1) The previous link to has been on that page for many years (at least six). According to the official policy as I understand it, links to material by known subject experts are allowed. All previous reviewers have kept that link because they agree that I am a known subject matter expert. In other words, everyone was happy. 2) The Bernoulli page was created by myself, a physicist, for teaching a college class. To my students I was an expert 3) The previous link was going to my ancient earthlink account. I'm dropping that account. 4) I still receive messages that people enjoy my animation. You have cited the official policy, but unless you have additional information I would still say the Bernoulli link should stay. Do you have any additional information? I did take the time to read the documentation but there may have been something I overlooked since I am not a regular wikipedia expert. I incorporated what I did find into my argument above.

I am fine with the removal of the non-Bernoulli page links. I am not a proven-expert in those fields. Markonius (talk) 16:21, 15 November 2013 (UTC)

I don't think it should stay, per policy. The fact that it has been sitting there for a long time really is not a compelling reason to keep it. But if you feel strong about it, I suggest you propose it on the article talk page Talk:Bernoulli's principle. In any case, if the other contributors think it should stay, then perhaps it can stay, but adding a string of these animations is a definite no-no. Cheers - DVdm (talk) 16:30, 15 November 2013 (UTC)

This blocked user's unblock request has been reviewed by an administrator, who declined the request. Other administrators may also review this block, but should not override the decision without good reason (see the blocking policy). Do not remove this unblock review while you are blocked.

DVdm (block logactive blocksglobal blocksautoblockscontribs deleted contribscreation log change block settingsunblockfilter log)

Request reason:

I understand that I have reverted multiple times, but as far as I understood the rules, I was reverting vandalism, which is not edit warring. Note that after the third revert for addition of unsoured content, Huggle automatically assumes and reports vandalism. See also Duoduoduo's comment on blocking admin's talk page

Decline reason:

If, as seems likely, you mean that because Huggle uses the word "vandalism" you feel free to assume that it is vandalism, and not decide for yourself whether it is, then you are completely misunderstanding Huggle. Every time you run Huggle, assuming you have not made some change to the default configuration, it warns you that you are responsible for your edits, and that use of Huggle is no excuse for what you do. (I can't quote exactly what it says, as I am not using Windows and therefore can't run Huggle to check the exact message, but it essentially conveys that message.) It is your responsibility to check what you are doing using Huggle, and if you fail to do so then you are every bit as responsible for what you do as you would have been had you made the same edits without any involvement of Huggle. JamesBWatson (talk) 16:13, 18 November 2013 (UTC)

If you want to make any further unblock requests, please read the guide to appealing blocks first, then use the {{unblock}} template again. If you make too many unconvincing or disruptive unblock requests, you may be prevented from editing this page until your block has expired.

Thanks, James. It's not that I put the responsability on Huggle. I was 100% convinced that the user in question was the same as multiple IP-abuser 84.135.*.*¨ who was active on the same article, and with similar edits. I reported this IP for vandalism here, and a bit later I reported user:DavidMichaelFabian here. The user report was left untouched and the IP was blocked a bit later by user:Materialscientist. I assumed vandalism and would have filed the same reports without Huggle. The reason why I mentioned Huggle, is that a fourth reversal for unsourded additions is generally automatically considered vandalism. I still think I was not edit-warring, but fighting vandalism. If admins in general think that this was indeed not a case of vandalism, then de-facto I misjudged, for which I offer my apologies. Cheers - DVdm (talk) 16:35, 18 November 2013 (UTC)

My last edit on Bioresonance

Hi there, I'm new to wikipedia editing and forgot to add in a summary as to why I edited, however the content I removed was because it was very obviously biased and unscientific.

Kinetic Energy

You recently removed my edit on the page 'Kinetic Energy'. I stated that the correct formula for finding Kinetic Energy is 'KE=mv' and not 'KE=(mv^2)/2' as is incorrectly written in most textbooks and on the current wikipedia page. The problem stems from the misguided 'Work Energy Theoerm' which states that 'Work done is equal to force through a distance'. This statement is incorrect and it can be easily proved that work done is in fact equal to the force applied to an object multiplied by the time it is applied. The proof of the accepted equation involves acceptance of the Work Energy Theorem, and the proof of the Work Energy Theorem involves acceptance of the Kinetic Energy eqauation. It is not hard to see the problem. For some reason unknown to myself, the vast majority of the Physics world has missed this, apart from one or two articles I have found on the internet, one of which I referenced. Please look into this yourself and think about the problem (providing you have a basic physics knowledge), and if possible, prove me wrong, instead of removing my edit without good reason (I understand that many people wouldn't want to accept this as it means they have been wrong for many years). — Preceding unsigned comment added by Seanhenley (talkcontribs) 13:35, 28 November 2013 (UTC)

Article leads allowed philosophical bias

DVdm, *Please* help me understand and reconcile the following statement from the Philosophy of Science article with relativity's insistence on observer dependent measurements yielding valid differences in whatever is observed and measured: ["Objectivity of observations in science... It is vitally important for science that the information about the surrounding world and the objects of study be as accurate and as reliable as possible. For the sake of this, measurements which are the source of this information must be as objective as possible."] Yet the observer-dependent basis of relativity (subjectivity in the broadest philosophical sense) prevails, and no philosophical criticism of its observer-dependent basis is allowed. The lead of every article is written by Wiki editors, and each reflects the *philosophical assumptions* underlying each article. This is most obvious in the field of relativity, in which the standard of objectivity cited above is clearly disregarded in favor of observer dependence. The results then negate the objective (established fact) and affirm the latter, as in my last example. The relativity of simultaneity would insist that the two beams strike their respective targets at different times (as differently observed)rather than a the same time, as factually established by the situational parameters. The same applies to my previous (and, yes, persistent) example of the diameter of Earth, which *does not in fact change* with changes in frames from which it might be measured. Since personal opinions and such criticisms as mine are not allowed, please explain why the article leads I have criticized are allowed to favor the philosophy of observer-dependence and disregard the most basic scientific intent to be objective, as above. Thanks. LCcritic (talk) 18:34, 2 December 2013 (UTC)

If you want to discuss the format and the content of the Relativity of simultaneity article, you should confine yourself to the article talk page Talk: Relativity of simultaneity. Do make sure that, with every word you write, you discuss the format and content of the article, not the subject or your personal opinions about it.

Also note that I honestly have no desire to discuss any aspect of the subject with you, as it is obvious—to me—that you have no idea what the subject is about. It has been explained many times by many contributors, and it looks like you are not interested—see the section wp:IDIDNTHEARTHAT in our guideline about wp:disruptive editing. I cannot help you and I am not here to educate you, and, I guess, neither can and are the other contributors that you have come in contact with on the relativity talk pages. I think it's best that you go elsewhere with your philosophy, as Wikipedia definitely seems not the place — see wp:NOT. Sorry. - DVdm (talk) 19:08, 2 December 2013 (UTC)

This will be my last "talk" addressed to you. I criticized the stated *editorial opinion* (which Wiki claims to not allow) in the lead of the article talk page... that there is no such thing as two events happening at the same time, that it all depends on 'who sees what and when.' You gave me another warning that it was inappropriate and disruptive, even though that talk page was discussing the conditions required for confirmation of simultaneity. Then I asked you how the Wiki piece on "Objectivity of observations in science..." reconciles with relativity's absolute insistence on "subjective" frames of reference as all 'equally valid." Now you say that too was inappropriate. I know that you personally dislike me and believe that I am an uninformed crank. ("... it is obvious—to me—that you have no idea what the subject is about.") I did in fact teach philosophy of science and have studied relativity in depth. You are obviously biased against anyone who criticizes relativity, so you are about to "block" me as a contributing editor. You refuse to address my examples of objective science, including the fact that Earth's diameter does not change with how it might be observed or my example above of a case of established (by the parameters set for the "experiment") simultaneity, not dependent on various observers. That was part of the discussion in the article talk page, which you said off topic. In other words, no criticism of the dictum of observer dependence is allowed, even in the talk page dedicated to discussion of the relativity of simultaneity! "Power corrupts"... LCcritic (talk) 19:45, 3 December 2013 (UTC)
You say:

"In other words, no criticism of the dictum of observer dependence is allowed, even in the talk page dedicated to discussion of the relativity of simultaneity!"

You see, that is what you don't seem to understand even after explicitly being told several times by several people and having been pointed to our wp:talk page guidelines so many times. Read the guideline. Among other things it says:

* Stay on topic: Talk pages are for discussing the article, not for general conversation about the article's subject (much less other subjects). Keep discussions focused on how to improve the article. Comments that are plainly irrelevant are subject to archival or removal.

That talk page is not dedicated to discussion of the relativity of simultaneity. Not even close. The talk page is dedicated to discussion of the article about the relativity of simultaneity. - DVdm (talk) 21:06, 3 December 2013 (UTC)
I must change my mind about “my last ‘talk’ addressed to you.” First, Wiki editors wrote the article and Wiki editors discuss improvements to it. That means that the lead emphasis on observer dependence denying simultaneity independent of observation is in fact a philosophical point of view, albeit mainstream relativity. It should not be presented as absolute fact, i,e., that simultaneity depends on observations, which disagree, therefore negating that any two events can happen at the same time independent of observation. The 2nd Paragraph Illustration section discusses the requirement for two events separated by distance as pertaining to the relativity of simultaneity. The car crash illustration was discussed as being one event occurring at one location, therefore not relevant to the simultaneity discussion. You agreed, specifying the situation requiring “...whether two distinct events occur at the same time..., and then remove the car crash sentence altogether.” My contribution set up such a situation in which the simultaneity of beams striking two separate targets could not be denied by observers seeing them happen at different times. Finally, after participation in the previous discussion, you declare such discussion “off-topic chat” as per the guidelines as you interpret them. Then you ‘slam-dunk’ my participation in the above conversation, saying, “Alas, on article talk pages we are not allowed to discuss our own philosophical, psychological, or even scientific views and musings about the subjects of our articles.” Iow, you and those above are allowed to bring up examples and discuss them for relevance to simultaneity, when it suits you, but then it becomes inappropriate if one should introduce an “iron clad case” of simultaneous events (see parameters of my example) which actually criticizes the assumption made by the article lead editor (and mainstream relativity of simultaneity.) I ask you to consider the above objectively, setting aside your apparent hostility toward me as a critic. LCcritic (talk) 20:08, 4 December 2013 (UTC)
Indeed, your "contribution set up such a situation in which the simultaneity of beams striking two separate targets could not be denied by observers seeing them happen at different times." That is, starting from your own wp:original research, discussing the subject, not the article. We are not allowed to do that.
I feel no "hostility toward you as a critic". I try to explain to you how Wikipedia works. So have others at Wikipedia talk:WikiProject Physics/Taskforces/Relativity#Criticism of relativity not allowed. It looks like we cannot help you understand how Wikipedia works. - DVdm (talk) 20:44, 4 December 2013 (UTC)
You have not explained how Wiki works such that you and other editors can discuss the parameters required for simultaneity and give examples in illustration and I can not. If indeed my example of simultaneity can not be denied, and it can't, it stands as a criticism of the concept that simultaneity depends on 'who sees what when' as the editors, including you, were discussing. Your reply totally ignored that issue... another example that criticism of the article is really not allowed. Rather it is for editors to simply "rubber stamp" approval of the dictum that simultaneity depends on observers, and no example to the contrary is allowed. Do you not hold yourself to the same standard you demand of me? LCcritic (talk) 19:57, 5 December 2013 (UTC)
Your example of simultaneity as a "criticism of the concept that simultaneity depends on 'who sees what when'", is wp:original research and not allowed in Wikipedia, so it has no place in articles or on article talk pages. It is also of no interest to me, so it has no place on my talk page. - DVdm (talk) 20:23, 5 December 2013 (UTC)

──────────────────────────────────────────────────────────────────────────────────────────────────── So you refuse to explain why you and others were allowed to discuss parameters, examples and requirements for simultaneity in the context of relativity but I was not. You also refuse to address my title for this discussion with you, i.e., under what rule editors are allowed to endorse a specific philosophy when writing such an article, i.e., that simultaneity depends on observers... even though my example proves otherwise. You are not only not interested in real criticism in this discussion but you will not allow my criticism of the article (in the talk page) addressing the observer-dependent philosophy/assumption upon which the whole article is based. This is going nowhere. Please disabuse yourself of the pretense that there is no hierarchy of authority here. You bend the rules to suit yourself, threaten to block me for protesting/criticizing and will not address any of these criticisms. Done. LCcritic (talk) 18:54, 6 December 2013 (UTC)

Please note that I cannot block you. All I can do, is explain some of the rules, warn you, and eventually report you for (article) talk page disruption by repeatedly using such talk pages as soapboxes for your own original research and ideas about the subjects. Such reports can result in being blocked for disruptive editing. See wp:IDIDNTHEARTHAT.

I am sorry, but nobody here seems interested in your criticisms. You will have to learn to live with that, and I cannot help. - DVdm (talk) 20:28, 6 December 2013 (UTC)

Correcting information on Alderney Week

Hello! We edited information on Alderney Week earlier today and received a message from you saying that I should not add unsourced information. However, the information that is on the page is incorrect. If you look at you will see that the Daft Raft race took place on a Thursday in 2013 and the Man Powered Flight and Duck Race were held on the Saturday. You will also notice that tide times are given for each day of the programme because this has an impact on the events that are held on any given day. There was no Battle of the Bands on Thursday or any other day of Alderney Week because this event has not been part of the programme for a number of years. We fully respect the fact that Wikipedia needs to be credible but it would have been helpful if you had asked for sources rather than threatening to block us. As the organisation with responsibility for tourism on Alderney (and as employees of the States of Alderney) our primary purpose is to make sure the island is represented accurately on a valued resource such as Wikipedia. Please can you advise us on the best way for us to get our edits reinstated? Many thanks--21:51, 12 December 2013 (UTC)Visitalderney (talk) --Visitalderney (talk) 21:51, 12 December 2013 (UTC)

Hi, your best bet is to go to the article talk page Talk:Alderney, and explain there to the other contributors and reach some consensus—see wp:consensus. If after a few days nobody has responded to your proposal(s), feel free to make some properly sourced changes to the article, making sure to mention the talk page in your edit summary. Please do note however that, as "the organisation with responsibility for tourism on Alderney", you might have a conflict of interest—see wp:COI. Good luck. - DVdm (talk) 22:01, 12 December 2013 (UTC)

Many comments suddenly removed

Why did you unilaterally remove the comments I made on several talk pages? Speling12345 (talk) 10:05, 13 December 2013 (UTC)

I replied on your talk page. See [13]. - DVdm (talk) 22:08, 13 December 2013 (UTC)
You, replied on my, talk page? However, you replied 2 minutes after I posted. Besides the timing issue, did you obey Wikipedia guidelines? Speling12345 (talk) 10:12, 13 December 2013 (UTC
I had put the comment there before you posted here. Please keep our conversation on your talk page. Thanks. - DVdm (talk) 22:13, 13 December 2013 (UTC)

King vs Magnate

Hi I would like to ask why you would refer to James Drummond Dole as a "pineapple magnate"? I wonder because the Wikipedia article refers to says "Also known as the Pineapple King" Master Troll Rocks (talk) 19:13, 19 December 2013 (UTC) Master_Troll_Rocks Ps Merry Christmas!

See this edit summary. Such a list page is not meant to provide that kind of content. It's a subtle thing, and certainly not worth edit warring over. - DVdm (talk) 19:21, 19 December 2013 (UTC)
Note - See also this edit summary. Meanwhile it looks like you were blocked for this. When your block expires, feel free to go to the article talk to try to establish a wp:consensus for your point of view. Keep cool. - DVdm (talk) 19:28, 19 December 2013 (UTC)

Re:Tesla DAB

I was actually editing to match his primary notability, re:electrical engineer and inventor, not all his sub-monikers. I actually see no problem with nationality, its settled at the main article and any sniping around DAB pages and the like can be referred to the main article. He has a referenced national description so no need to dumb it down on Wikipedia. But left it for now ;) Fountains of Bryn Mawr (talk) 20:34, 23 December 2013 (UTC)

For me there's no problem with nationality either, but there has been some trouble in the past with other contributors.

Ok, good idea this. I suggest you make a similar tweak at 1943‎. Cheers and thanks. - DVdm (talk) 20:56, 23 December 2013 (UTC)

Um almost good, that is. You forgot the physicist. Hadn't noticed that :-) - DVdm (talk) 07:26, 24 December 2013 (UTC)

Olinto De Pretto

Hello! why did you delete my changes? Maybe I put the sources in a wrong way, but I guess you are better than me and you can write again my lines. Here the sources. Thanks for your help and happy new year!!! — Preceding unsigned comment added by (talk) 16:50, 27 December 2013 (UTC)

See the reason in my edit summary ([14]). Neither source qualifies as a reliable source — see our policy wp:Reliable sources. Further discussion should go to the article talk page Talk:Olinto De Pretto. Cheers and happy 2014! - DVdm (talk) 16:59, 27 December 2013 (UTC)
You write: " is not a reliable source". Just for curiosity, where did you read that the link is not a reliable source? Professor Umberto Bartocci is a serious scholar, the same about (deceased) professor Omero Speri and dr Piero Zorzi. Dr Dhananjay Khadilkar is a science correspondent for DNA, Daily News and Analysis; columnist associated with The Indian Express; writer for Scientific American and so on. — Preceding unsigned comment added by (talk) 15:29, 28 December 2013 (UTC)

Im sorry about the errors on the pages, im not real proficient at computers yet, I have tried to get accurate numbers for the albums on here, but since there is no real way of getting them have to go by what numbers have been given on certain websites. These albums haven't been recertified for a long time and trying to give them accurate numbers has been a nightmare, thanks for fixing things I will get better at this the more im on here, happy new year! — Preceding unsigned comment added by Hardrock 4171 (talkcontribs) 16:57, 30 December 2013 (UTC)
