Hey, I wanted to ask you guys a few questions about string theory. It seems like a really neat area, but is over my head. These questions are based on stuff I've gleaned from reading the "beginner" section popular websites: (0) Why study string theory? ----- (1) Is string theory (still) an active area in physics? Have there been any major advances in the field since the "revolutions" of 1984 and 1995 (dualities)? (2) Is string theory at the mercy of results from the Large Hadron Collider experiment? (3) How hard is it to get a job as a professor in string theory? (4) How many string theorists are there in the U.S? World? Thanks for any help!
