Strogatz, Steven H
2009
Chronicles thirty years of written correspondence between a student--the author--and his high school calculus teacher--Don Joffray--in which they discusses their shared interest in calculus.
Explains the ideas of math gently and clearly, starting with why numbers are helpful, and moving on to such topics as shapes, calculus, fat tails, and infinity.
