Does anyone know about Witten's early years such when he was in High School and University? He didn't even do physics as an undergrad and instead majored in history and minored in Linguistics. Apparently he tried other things after his BA like politics, economics and mathematics before finally settling into physics in grad school. How does someone be accepted into physics grad school without a physics undergraduate degree? How did he become a physics professor with only around 7 years of experience doing physics (presumably he had not done phyiscs in high school)?
