I learned several things today from websurfing.

From this comment by elzoro at Not Even Wrong, I learned that Richard Borcherds now has a weblog. The two posts so far are about physics.

From this comment by Peter Woit that the latest issue of the journal *Topology* is out, and the page that lists the editors is completely blank. (Remember that last year the entire board of *Topology* resigned to protest the journal’s high subscription fees, and started their own journal, the *Journal of Topology*.) I think that the publisher has to keep the journal going at all costs, since if the former editors of *Topology* succeed in completely supplanting their erstwhile journal, the commercial publishers will lose control of mathematical publishing pretty quickly.

From this anonymous comment at Computational Complexity, completely and cynically explains the rationale behind the Clay Millenium Prizes:

The point of the Clay prizes is not to provide motivation to solve the problems (anyone who solves one will have put in far more effort than a million dollars warrants), but rather to tie Clay’s name to the problems, so that nobody will ever discuss the Poincare conjecture without talking about Clay. To accomplish this, the prize has to be impressively large, on the scale of a lottery prize.
