Question[edit]

First of all, I want to thank you for your support. Although we've only recently begun entering the same circles, I feel like you and I are like-minded. I have great respect for your opinion, and you are always willing to discuss. In my recent successful RfA, I promised to be opened to recall with specific terms similar to User:TParis/Recall. Before I make any edits that require the mop, I wanted to cement my own recall process, including a list of editors who can specifically call for the recall of my administrative rights. Due to my high level of respect for you and your opinion, I wanted to know if I could include you on said list. Thanks, -- TLSuda (talk) 21:04, 1 March 2014 (UTC)

Hi! Just a quick update that while JSTOR and The Wikipedia Library discuss expanding the partnership, they've gone ahead and extended the pilot access again, until May 31st. Thanks, JSTOR!

It would be really helpful for growing the program if you would fill out this short survey about your usage and experience with JSTOR:

Noyce jpg[edit]

Dear Toshio, Thank you for notifying me about the image. You say "Please see the discussion" but all I see is you saying something is wrong. I don't see any discussion. It's a nice image of the cover of a very old book (please note the period typography), the author of which was killed in a tragic climbing accident nearly sixty years ago. He would have liked the cover to be in these articles, so I would ask you to think of his widow, his children and his grandchildren, to have a heart and desist from your pernicious course of action. Please unconsider it for deletion on the basis of a dead man's will, Regards, Ericoides (talk) 18:16, 22 April 2014 (UTC)

@Ericoides: This image is used in two articles, Wilfrid Noyce and 1953 British Mount Everest expedition. First of all, per WP:NFCC#10c, a non-free image needs a non-free use rationale for each article where the image is being used. The image currently has a non-free use rationale for Wilfrid Noyce, but not for 1953 British Mount Everest expedition. Secondly, a non-free image also has to satisfy WP:NFCC#8. Both uses fail to achieve this. In 1953 British Mount Everest expedition, the cover image just serves as a visual depiction of one of the Further reading items. The presence of the image does neither significantly increase a readers understanding of the article topic, nor would the article be incomprehensible without that image. The use in Wilfrid Noyce, while accompanying a quote from the book, also fails non-free content criterion #8. The image is not essential for a readers understanding of the article. The fact that he wrote a book about the expedition can be conveyed to the reader without them seeing an image of the book cover (they can still understand, what that part of the article is about without it). Also, from the point of copyright law, the book cover is not 'very old', it is still under copyright. -- Toshio Yamaguchi 20:16, 22 April 2014 (UTC)
My apologies, I wasn't being entirely serious. But I appreciate your serious reply. Keep up the good work! Ericoides (talk) 11:44, 27 April 2014 (UTC)

Numbers of the form 7^n + 2[edit]

Hi. I'm going to assume you have studied a little algebra in school; if not, you may need to learn a little of that first.

First, we observe that (3y+1)(3x+1) = 9xy+3x+3y+1 Now, if we write z = 3xy+x+y, we have (3y+1)(3x+1) = (3z+1) That is, if we multiply two numbers of the form "3 times something, plus 1", we get another number of the same form. 7 is of this form, so the same must be true for any power of 7, because 7^n = 7 * 7 * 7 * ... * 7 (n times). So any power of 7 is of the form "3 times something, plus 1". Now, if we add 2 to this, we always get "3 times something, plus 1, plus 2", which is just "3 times something, plus 3". This is obviously divisible by 3 in all cases, so (7^n + 2) can never be prime.

You can extend this reasoning to show that, for example, (11^n + 4) can never be prime, or that (23^n + 10) can never be prime, and so on. RomanSpa (talk) 14:35, 3 August 2014 (UTC)

@RomanSpa: Thanks for this explanation, this is very illustrative. I do appreciate your help. -- Toshio Yamaguchi 19:35, 3 August 2014 (UTC)
You're welcome. RomanSpa (talk) 04:20, 4 August 2014 (UTC)

Speedy deletion nomination of 800 Super Holdings[edit]
