That book list is odd for its absence of math books -- he had resigned an asst. prof. position at Berkeley (apparently without explanation), which is probably correlated with this -- and the absence of any books on the chemistry of explosives (my guess is that some authority decided it would be unwise to spread those book around. Another possibility is that he already knew all he needed to know . . . he was known to enjoy setting off bombs as a high school student). * [begin: more than you wanted to know alert] * I had one real encounter, and one second-order one, with Kaczynski. As a grad student in Berkeley in '70, my then girlfriend and I hired him to take a series of photos of us on the Berkeley campus (as I later learned, this was not long after he resigned). Then about 15 years later, when I was teaching computer graphics in the Berkeley (EE)CS dept. at Berkeley, one of my very best students picked up a package he saw in a computer room and it exploded, severely injuring one of his hands and one of his eyes. The student was already an Air Force captain, and a few days later received an acceptance to enter the astronauts program -- both of which career paths were closed to him after the bomb. (But he's now a successful professor of electrical and computer engineering at U. Colorado, Boulder.) * [end: more than you wanted to know alert] * --Dan
