hyperbolic plane (the non-degenerate two-dimensional symmetric bilinear form with a norm 0 vector)

You're right; I should have paid more attention before linking to "hyperbolic plane". Michael Hardy 00:36, 16 June 2006 (UTC)[reply]

Thanks for creating the article on Sethian

I just found that you created the article on James A. Sethian. I requested the article (along with one on Stanley Osher) back in October 2005. Nice to see it created. I've had the opportunity to hear both of them speak on level set methods. — ERcheck (talk) 21:01, 22 July 2006 (UTC)[reply]

Which Chevalley?

Any idea whether my guess is right, in my recent edit to Jacques Herbrand? Was I too hasty? Michael Hardy 00:28, 24 July 2006 (UTC)[reply]

I've never heard of Henry Chevalley, and I would guess that this is a copying error, but I dont know for sure. If you cant get hold of a copy of the book the quotation is from, then my suggestion is delete the first name and the link; that way the article is correct whatever the guy's first name is. R.e.b. 00:46, 24 July 2006 (UTC)[reply]

...and now I've found a web site attributing that quote to Claude Chevalley, and I'm not surprised. Michael Hardy 01:26, 24 July 2006 (UTC)[reply]

TeX magic

I notice you removed the TeX magic string "\,\!" from a displayed formula at Wilkinson's polynomial, saying it caused display problems with your browser. Are you sure it wasn't a server transient? The only thing that magic incantation does is force PNG display, and it's used everywhere and recommended at Help:Formula. In the equation in question, the PNG happens anyway because of the fractions, but I'd like to be sure you don't go around removing this more broadly. The way TeX sees this, it should be completely harmless, because "\," is a thin space and "\!" is a negative thin space. Furthermore, because it forces a PNG the appearance of the formula should have nothing to do with your browser. --KSmrqT 03:08, 30 July 2006 (UTC)[reply]

I'm puzzled about what is going on. The formula displays correctly without the thin spaces, but just displays raw TeX with them. The next formula seems OK even with these thin spaces, just to make it more mysterious. Maybe there is some bizarre error elsewhere in the article which somehow causes this problem; I've noticed before that wikipedia errors can cause strange effects a long way away. R.e.b. 03:22, 30 July 2006 (UTC)[reply]
And now the problem seems to have vanished; everything displays fine. Another irreproducible sporadic bug. R.e.b. 03:38, 30 July 2006 (UTC)[reply]

Floating points on Pilot ACE

Hi. What was your source for this edit to Wilkinson's polynomial, in which it is claimed that the mantissa of floating point numbers on the Pilot ACE is stored in 30 bits? I'm asking since it was subsequently changed to 24.

Cheers, Jitse Niesen (talk) 10:27, 3 August 2006 (UTC)[reply]

See section on Pilot ACE precision on article talk page. R.e.b. 16:23, 3 August 2006 (UTC)[reply]

Piotr Blass

You can see that the AfD is an emotion-driven process. The article annoyed these children and that it why it will be deleted. I cleaned up the article so that you can see what a surviving article might have looked like. -- 75.28.164.100 04:01, 5 August 2006 (UTC)[reply]


thanks could you send me the cleaned up article i cannot find it i tried resubmitting and was deleted within 5 minutes please send me e mail at pblass2002@yahoo.com zariski lives! piotrek

thanks !!!!!!!!!!!! r e b you are a real geometer and a friend not a child! keep up your editing work on Zariski surfaces e mail me if you wish to get into research best piotrek blass www.pblass.com

could you help me construct my piotr blass page so that it will not be rejected by children? thanks in advance piotrek who are you? resume perhaps? shalom piotrek pblass2002@yahoo.com


thanks r e b I shall take a look at characteristic two enriques surfaces

i may have to consult with my friends dolgacev,crew,cossec but we shall get this right i remember mumford's and zariski's inspiration on this topic it was fun with a bit of yelling back and forth

how can we control the red guards children who play with diamonds of knowledge with so little respect i grieve for the web sometimes but we shall overcome cyberspace is quite large! unfortunately i see the two party system invading wikipedia that is for another day shalom galois lives! best piotrek

Dear r e b I shall try to follow your advice although I am in the middle of campaigning and teaching and research as I am sur you understand.

Could you help me locate the admin who deleted my article so i can e mail him to put it back on my user page? The children play somehow I am reminded of William Goldings novel from the 1960's that I read in England.....Lord of the Flies Have you read it?

The disturbing thing is that grown ups seem to be using the children to do some unsavory stuff.... We shall overcome The web is too wonderful to be so misused. And yes our Ulam movement did pioneer a good chunk of the web although the children will not hear about it preferring to worship berners lee from afar.... he is apolitical and apparently convenient for the children and some others best piotrek ps what math do you do? pb galois lives!

Exotic R4

Hi, I wrote some comments on the above article's talk page. Could you take a look? Orthografer 19:21, 8 September 2006 (UTC)[reply]

I expanded the article; I hope this answers your questions. R.e.b. 20:36, 8 September 2006 (UTC)[reply]

PIOTR BLASS AGAIN

YOU RESTORE MY FAITH IN THE HUMAN RACE COULD YOU HELP ME RESTORE MY WRITINGS ON ZARISKI SURFACES AND SHELTER THEM FROM THE MARINE BIOLOGIST'S WRATH THANKS YOUR FRIEND PIOTREK

extension (mathematics)

I created extension (mathematics) as a new disambiguation page with more than 30 entries. I think it ought to get organized into sections and subsections. Probably you are better qualified than anyone here to help with at least some portions of this task. Michael Hardy 21:33, 12 September 2006 (UTC)[reply]

...and now someone's started on this. Probably more could be done... Michael Hardy 22:05, 12 September 2006 (UTC)[reply]


THANK YOU

God Bless you my friend You restore my faith in the mathematical community! and more! Feel free to contact me and to collaborate Enriques surfaces in char two coming soon shalom ve bracha shana tova ve hatima tova piotrek
