morning study session (Oct 27, 2009)

Today's M's turn to lead a study session, and it was about brainstorming how to explain poi to beginners. He plans to write an article on poi, so he's going to explain me about it as sort of a test case. No concrete outline yet.

Later on, I went to a cafe alone and studied elementary combinatorics, to get ready for an exam scheduled on coming Sunday. I probably need to review trigonometry and geometry.
