Question

Dear MO-fellows, Happy New Year !

Taking google as an example: https://www.google.com/zeitgeist/2012/

Why not to make a list of noted math events in 2012 ?

E.g. 15 December 2012 Museum of Math was opened in New-York (see also http://mathoverflow.net/questions/50343/what-would-you-want-to-see-at-the-museum-of-mathematics )

Mochizuki announced the proof of ABC conjecture. (see also http://mathoverflow.net/questions/106560/philosophy-behind-mochizukis-work-on-the-abc-conjecture )

I think Elsevier boycott should also be noted.

PS

Good luck, health and great achievements in new year !
