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.
Here’s something that I sent in our QFT-II Google Classroom:
🎉A milestone in our QFT education! Here is a lecture straight from one of the creators. A video recording of Feynman talking about the calculation of the anomalous magnetic moment :). If I am not wrong, he is referring to the value of g/2.

"And then it turned out surprisingly, it was worked out more or less independently but three guys who got Nobel Prize, one of which is here (: and uh... professor Schwinger, that's not me; one of the other ones ... Schwinger for example calculated this and found it was like...."
