about Khovanov homology and I was frustrated to
not understand it, but I had no idea it was related
to geometric Langlands"
"In some cases, I am
still struggling to understand things that physicists
did quite some time ago that are very relevant.
Just to give one example, the Gopakumar-Vafa and
Ooguri-Vafa formulas have been very influential
for algebraic geometers, but as a physicist, I was
never satisfied that I understood them."
"producing rigorous proofs requires very detailed
methods. That makes it hard for a physicist, and so
I myself have only done that in very special cases
where I thought something was really missing that
was actually simple enough that I could help do
it if I had the right collaborator. "
