Long Needed Update

Alright, General Relativity and Advanced Quantum Mechanics are done with and Quantum Field Theory with David Tong and Statistical Mechanics with Leo Kadanoff began last week. The notes used for the QFT course are here on Tong's website for those who are interested. For Stat Mech we are using some interesting and unconventional notes in book form written by Kadanoff.

Tong is an excellent and clear lecturer and presents the subject superbly. The ideal introduction to QFT I must say. It turns out, his first post doc was at TIFR and he's been to Aurangabad (my hometown) several times. Which was good to hear :)

Kadanoff is one of the people who was involved in creating some of the most profound and fundamental ideas in modern theoretical physics - Renormalization and Universality besides a host of related ideas. It is quite an honour to be taught by him, and he is always happy to have lunch with us and discuss various subjects. He is 82, and still remarkably sharp. Today he told me that Cellular Automata are a field research that is slowing down since nothing of major importance is happening there, and that the Santa Fe Institute started in the 70s to explore complex systems has more or less abandoned the program to find a unified framework for complex systems and emergent phenomena. You study the subject one complex system at a time, he said.

Im quite looking at complex systems, information theory, cellular automata, chaos and related things actually, they interest me, and Id like to find something fundamental, important and interesting to work on there.

In the meanwhile, Ive got to ensure I become reasonably good at QFT and Stat Mech. neither of which are trivial. to say the least.
