Abstract

In his 1622 work The Assayer, Galileo commented on the necessity of mathematics for understanding the natural world. "Philosophy is written in this very great book. . . . It is written in mathematical language and the characters are triangles, circles and other geometrical figures." More than 300 years later, debating math education at the 1958 International Congress of Mathematicians, French mathematician Jean Dieudonné interjected: "Down with Euclid! Death to triangles!".
