Are there really people who actually read this many textbooks? I read half the textbook “Rigid Body Dynamics Algorithms” and it took a couple months. And I had time because I read it for a research project in grad school. I can’t imagine going home after work and grinding these textbooks for years.
I used to have the copy of TAOCP vol 1 - 3, and eventually only read vol 2 because I was interested in (pseudo) random number at that time.... :D
