I had another crying fit and quit again before the first term was over. Part of the program would have involved taking the A+ and Network+ certification exams. I got the books and passed those on my own, but never ended up converting them into a job; maybe I could have if I had tried harder. -In fall 2008, I got the idea that my autodidacticism should include mathematics and started studying linear algebra from the textbook I had used at UCSC.

When I had had my fill of linear algebra, I followed it up with work from books on complex analysis and discrete math, and various other math and programming excursions I came across: I [figured out how 1/x can be the derivative of log x even though the latter isn't defined for x≤0](http://zackmdavis.net/blog/2011/12/the-derivative-of-the-natural-logarithm/). I worked out a formula for the disjunction of independent events of probablity _p_ (and was later informed by a friend that DeMorgan's law gives a much simpler formula). I got a quantitative evolutionary theory book and tried to generalize the Hardy–Weinberg law to the science-fictional hypothetical case of a genome having three alleles per locus (in which case the famous Punnett square becomes a cube). I kept all my notes and exercises in a continuous sequence of numbered pages divided into two columns. -[TODO: Punnett cube, derivative of the natural log 20 March 2009, probability of a disjunction] +In April 2009, I visited the UCSC campus to see my friends and visit the office hours of Prof. Patrick Tantalo (who had taught that linear algebra class) and Prof. Aptheker. I told Prof. Tantalo about my mathematical exploits, but disclaimed several times that I wasn't even a "math person"; he wisely asked what that even meant. -I kept all my notes and exercises in a continuous sequence of numbered pages divided into two columns. +[TODO: Aptheker visit; check email for more evidence of Aptheker intent] + +I suspected I might have gotten more studying done than my friends during the visit. + +[TODO— + * anxiety about the idea of being a programmer + * Introduction to Automata Theory, Languages and Computation for SingInst internship (Anna suggested just Turing machines, but I did the earlier stuff) + * vector calc + * microeconomic theory +] [TODO— - * April 2009 UCSC visit, Tantalo, Aptheker; Sean and Luke - * "When you try to solve a math problem and fail, you at least have the notes, but half of a computer program is nothing.
