A nice guide. I am currently following it.

a.k.a. “How to get started learning QFT as an undergraduate.”
5 Jan 07: Slight updates (added more details) to a few of the reviews, and an added caveat.
Quantum Field Theory (QFT) plays a key role in all branches of theoretical physics. For students interested in high energy theory, exposure to QFT at any early stage is slowly becoming the standard for top American graduate schools. This is already the case for the Mathematics Tripos at Cambridge.
However, the ‘standard’ American undergraduate physics curriculum doesn’t typically encourage Quantum Field Theory, nor do smaller liberal arts college regularly offer QFT courses. It is often expected that a student will take a second year of ‘graduate’ quantum mechanics before taking QFT.
An inspired student with adequate background should be able to take quantum mechanics in his/her second or third year and then progress directly to a ‘real’ QFT course with a bit…

Just finished the first chapter of Shankar, which is truly amazing. Shankar’s introduction to Hilbert space and Delta function is clear and thorough. The material is indeed quite new to me, but I just felt exciting learning all these new concepts. Certainly, I think I need to go back to this chapter later and reread in order to really learn the stuff well.
I have a feeling that this quarter shall be amazing.
Just read about the advance of perihelion calculated from general relativity. Finally see how to derive this notorious value now. Isn’t it just amazing that everything is derived simply from Schwarzschild metric and the geodesic equation of a particle in this metric!
Definitely should learn more GR in the future!
