Puzzle 20

John Baez

Q: Edward Witten is probably the most famous string theorist in the world. Why is he teaching particle physics on a street corner - with a megaphone?

A: Because he's taking part in the "Frist Filibuster" at Princeton University's Frist Campus Center - a demonstration against the so-called "nuclear option" in which the Senate would prohibit filibustering judicial appointees.
