Euclid: Book IX, Prop. 36First posted: January 28, 2007 Jumping off from The Book of Numbers by Conway and Guy, we explore a proposition of Euclid's, that the Mth triangular number, the Ms being the Mersennes (as we call them today), is also a Perfect Number. The purpose of this clip is to demonstrate how Python might form a useful hybrid with various math topics, providing cross-training in two disciplines: mathematics and computer science. This is an approach I've long recommended, based on field experience as well as intuitive factors.
