Okay, so I did classical differential geometry this semester. The teaching style was not so rigorous. It was not that abstract either. This is a post to put things in perspective. I want to pick out the essentials of the course, so that I don't regret not learning an interesting subject.
Back when I was in second and third years here at NISER, I found the idea of Quantum Field Theory quite exciting and was looking forward to get to know how all the fundamental stuff is calculated. I think much of the longing came from the book Surely you are joking Mr. Feynman. I wished for someone to just talk about it and pass the feels. Of course David Tong did, and I was waiting to see the calculations myself. Of course, I was no way ready until this semester to understand such calculations, but you get it. I was excited, and also patient. And today we finished calculating the anomalous magnetic moment! Yes, for which Schwinger was awarded the 1965 Nobel Prize, and is one of the most accurate theoretical and experimental agreement in the history of phyiscs. I am elated and I am going to celebrate this with a series of articles on some fundamental QFT results, that could probably keep the excitement high for the studfents in their junior years. I'm writing this atleast for my third year self, and out of as I said celebration of QFT education.
In this drama of mathematics and physics, which fertilize each other in the dark, but which prefer to deny and misconstrue each other face to face—I cannot, however, resist playing the role of a messenger, albeit, as I have abundantly learned, often an unwelcome one.
