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 What would you want to see at the Museum of Mathematics? )

Mochizuki announced the proof of ABC conjecture. (see also Philosophy behind Mochizuki's work on the ABC conjecture )

I think Elsevier boycott should also be noted.

PS

Good luck, health and great achievements in new year !
