"How should we make it attractive for them [young people] to spend 5,6,7 years in our field, be satisfied, learn about excitement, but finally be qualified to find other possibilities?" -- H. Schopper

(btw: entire careers have been based on susy, without a spec of experimental evidence: on might say, it is not even wrong)

I'm not remotely qualified to comment on the content, but I was very lucky to have Nima as a professor in college. He was an incredibly exciting lecturer--he practically glowed with intellectual energy.

Interesting thing that he mentions in the beginning something like "Amplituhedron is so simple I could explain it to high-school students". I'd sure love to hear that explanation as my knowledge of physics/maths is not much better than that of hs students.

edit: Also the hand-written presentation slides are lovely.
