^{*}It's been three years since the Perelman program was announced, about 30 since Thurston's geometrization conjecture, and 102 since Poincaré first declared that the 3-sphere was unique among 3-manifolds for having trivial fundamental group; there were, of course, many more stops along the way. The answers to those questions are probably much larger than I would care to guess.

So, who's working on P vs NP?
