Some links I've posted over on Google+ over the last couple of weeks (and reposted here, among other reasons, because I don't trust G+ to give me a usable interface for finding all of my old posts there):
UIUC rescinds the hire of an outspoken critic of Zionism (G+ – as one might guess this led to much discussion)
Spirographic pancakes: (G+)
Hales finally gets computer verification of his sphere-packing proof, with inflammatory statement about journal referees (G+)
Are 90% of academic papers really never cited? For some reason this came up on a Wikipedia deletion discussion: someone wanted to argue that a half-dozen publications with 100+ citations each shouldn't count for much because basically everyone achieved that just by waiting long enough, and used this as evidence.
