My Electronic Math Diary


The following are my diary notes about various math books that I’m reading or read, and just math in general. Their primary purpose is to make sure that I don’t forget interesting ideas that come to me, but at the same time they might be useful to others as well. If you see anything interesting to discuss, a mistake, or a typo, feel free to leave a comment below or send me an email at
