Today I received a purported message from the American Physical Society. It was an html page with claims like these: Not necessaries more experiments, theories and models about the particle and atomic world, because now exists the very simple and real physics of these! As Moshe would say, this is a typical crackpot comment. However, [...]

Today on the arxiv Oswaldo Zapata wrote an essay on issues about fact and belief systems in superstring theory. Naturally, Peter Woit decided that this was really important and wrote a whole article about it. Here I will collect a few recollections that serve as a rebuttal/complement to some of those discussions. Mostly, I feel [...]
Bad cookie theory.

I have a theory on why cookies at various academic department sponsored events tend to be low quality in general, but not completely inedible. If the cookies are very good, the first few people who arrive at the event have a feast of cookies, and there are only a few crumbs left for the rest. [...]
Group representation theory notes

I just finished a quick primer for my class on Advanced QFT on Representations of Lie algebras and useful facts about them. Here is a link to the lecture notes. It’s a hands on approach with no proofs, but at least it makes various concepts a little bit more accessible and can serve for a [...]
