from Prof. Pavel Etingof from the Math dept of MIT.
I came across this interesting “warning” while browsing thro MIT ‘s wonderful Open Course Ware site. He advises physicists not to take his course titled ” Geometry and Quantum Field Theory” , as he thinks that it would be of little use to them. He even comments that
“It is important to note that the instructor knows less QFT than a graduate student specializing in QFT or string theory.”
