The story of the year goes to Grigori Perelman, his proof of the Poincaré Conjecture, his declining of the Fields Medal and Shing-Tung Yau's portrayal in the New Yorker and the lawsuit threat that followed. Science magazine named Perelman's proof the Breakthrough of the Year.
Meanwhile the theory-friendly number theorist Terrence Tao accepted his Fields medal and CMU cryptographer Luis von Ahn and Tao won MacArthur genius awards.
My post FOCS Accepts and a Movie received over 200 comments mostly about the state of the theory conferences. Sadly the movie and the rest of the science.tv site have disappeared. I also finished my favorite complexity theorems, at least for now.
Thanks to guest blogger Claire Kenyon, guest posters Eldar Fischer, Jérémy Barbay, Janos Simon and podcast guests Luis Antunes, Eldar Fischer, Troy Lee and his opponents. The biggest thanks to Bill Gasarch who did all of the above several times.
Happy New Years to all my readers and let's look forward to an exciting FCRC and a renewed US commitment to increased funding in the basic sciences.
