Description: Mathematical Circles are for students of high school age or younger who want to increase their abilities to reason about mathematical problems. Students who study in circles learn to do mathematical olympiad-style problems (essay or proofs, not quick answer). Handouts, available in PostScript or PDF format, from some math circle sessions cover the topics of mathematical induction, matrices, geometric transformations with matrices, polygons, general encryption, the RSA encryption algorithm, geometry of the circle, mathematical biology, Pick's Theorem, general combinatorics, combinatorics problems, counting derangements, and counting poker hands. Also, the author's recommendations on How to Lead a Math Circle Session; and links to other math circles local to Berkeley and the greater Bay Area, California.
