A manifesto for freeing math from the drudgery of traditional teaching by a brilliant mathematician.
Paul Lockhart became interested in mathematics when he was 14 (outside the classroom, he points out). He dropped out of college after one semester to devote himself exclusively to math. Based on his own research he was admitted to Columbia, received a PhD, and has taught at major universities. Since 2000 he has dedicated himself to "subversively" teaching grade-school math.
