Venn diagram

That's a very nice diagram you linked from the Reference Desk. I have a suggestion -- no, two suggestions -- for making it even more complicated. (1) Some people are under the impression that the pound is one of those currencies that have been replaced by the euro. Adding the set of those countries whose currency actually has been replaced might therefore be informative. (2) Certain European countries are in customs unions, meaning that people and goods can generally pass freely between them without border checks. I know of at least three separate customs unions: the UK plus Ireland (I don't know if Man and the Channel Islands are included), the Nordic countries, and the largest group, the Schengen countries. Oops, while setting up those links I see that I'm out of date; the last two unions have now combined into one. Anyway, these groups might also be worth depicting. If you like.

Gerrymandering Mathematics

With reference to your question, when I designed that image to illustrate the article, I realised that in an election with 2 parties, 3 was the smallest number of districts to produce a winning minority, if ties cannot favour either party (so must not happen). Obviously, 1 district can lead only to the stronger party winning. With 2 districts, the best the weaker party can do is to force a 1-1 draw.

I then calculated the fewest voters that 3 districts could be equally divided to yield 3-0 (a), 2-1 (b) and 1-2 (c) results. Let's call give the stronger party S and the weaker one W. S has s voters and W has w voters, making a total of n = s + w voters. The critical cases to satisfy are extreme cases (a) and (c).

Case (a): In each district, S must beat W by the slimmest possible margin i.e. 1 vote (assuming no tie-breaks). Thus for 3 districts, S beats W by 3 votes in total, so s = w + 3.

Case (c): In one district, S must beat W by the greatest possible margin i.e. 100% votes, using up (n/3) S votes. In the 2 remaining districts, W must beat S by the slimmest possible margin i.e. 1 vote (i.e. 2 votes in total), hence w = (s - n/3) + 2. ("- n/3" is due to the votes used up earlier.) Substituting n = s + w gives w = s - (s + w)/3 + 2 or 4w/3 = 2s/3 + 2. Multiplying both sides by 3/2 gives 2w = s + 3.

Solving the 2 simultaneous equations gives s = 9 and w = 6, as in the example. Hope that helps! cmɢʟee☺τaʟκ 00:21, 17 July 2011 (UTC)[reply]

Quick formatting note

Hello: I decreased the size of your map by converting it into a thumbnail. I hope you don't mind; the original image was extremely large. You can do this yourself in the future by using the "thumb" parameter, e.g. [[File:NavajoNation_map_en.svg|thumb|left]]. Regards, Orange Suede Sofa (talk) 17:00, 12 October 2011 (UTC)[reply]

Dual License of Photo / Permission?

Got a resume?

Hi, I just found your videos on the Electoral College to supplement my explanation to a friend. They're great! but I think my friend will have a hard time with the speed; she's older and doesn't hear the best, so I think it just goes whizzing by too fast for her. Do you have them posted somewhere else in slower speed?

But what I'm here about is wondering just who C.G.P. Grey is, besides a dual citizen of the EU and the USA. Wanna tell? Best regards, Yopienso (talk) 16:55, 5 September 2012 (UTC)[reply]

You can read the text of the videos on my blog. --CGPGrey (talk) 17:14, 5 September 2012 (UTC)[reply]

Ah, thanks! That's a great help. Yopienso (talk) 17:18, 5 September 2012 (UTC)[reply]

Greetings. There is an ongoing deletion discussion on Commons here about an image you have been involved in to some degree. If you could go there and comment, that would help us to figure out what's going on. Thanks! – Quadell ^(talk) 17:13, 19 June 2013 (UTC)[reply]

Quick question

Dear Mr Grey,

Sorry for posting this here - but I did not know any other way to contact you. I tried YouTube but got a message saying that you have contact lock, which prevents you receiving messages from people you don't know. Not that I blame you of course :)

Firstly, it would not be possible to send you a message without telling you how much I love your videos. They're informative and amusing, and I very much like your style. Thank you!

I wanted to know what animation software you use to create them. I would like to create a similar informational video on a particular topic - and when I imagine making such a video, your own style of presentation jumps to my mind as an excellent way to do it.

So could you point me in the right direction?

Thanks,

‎ Eurosong, you could try E-mailing him from his Wikipedia account. He does have it 'activated'. 220 of ^Borg 18:38, 22 April 2016 (UTC)[reply]

An idea for your article

I have a little idea for the CGP Grey article. Could you create an image of your avatar that you use in your videos waving and saying "Hello Wikipedia", then upload it to the commons? This has been done for other articles (Example) and I think a snapshot of your art style might be useful. Thanks. Zero Serenity ^{(talk - contributions)} 19:15, 27 November 2014 (UTC)[reply]

Come on...

Grey,

I'd like to improve the Hello Internet article, but you're making it very hard for us. Is it too much to ask that you would give a few interview to random journalists about the podcast? We can't put the most basic facts about Hello internet in the article until they appear in some newspaper somewhere. Please bend your own rule. You will probably regret it, but it's worth it. Thanks.

ANI

Hi CGP Grey. Just to let you know, there is currently a discussion at the administrators noticeboard for incidents over whether to prevent your full name being put in your article via semi-protection or not. To be honest, I'm not sure your input would be welcomed, but I thought you should know.

Thanks, GreyGreenWhy (talk) 16:23, 24 April 2018 (UTC)[reply]

Of course, as you know, when I said "your article" I meant the article CGP Grey which just happens to be about you and over which you have no ownership. Sorry about that, GreyGreenWhy (talk) 16:26, 24 April 2018 (UTC)[reply]

Thanks for commenting and sorry to bother you again, just wanted to let you know that there is now a suggestion there from User:GreenMeansGo for you to email WP:OTRS (the Wikipedia:Volunteer Response Team) to verify your identity. GreyGreenWhy (talk) 17:51, 24 April 2018 (UTC)[reply]

Thank you. It is done. CGPGrey (talk) 17:53, 24 April 2018 (UTC)[reply]
