BOOK REVIEW: The Man of Numbers: Fibonacci’s Arithmetic Revolution by Keith Devlin

Review by Devin Powell

Leonardo of Pisa, also known as Fibonacci, is best remembered today for introducing a sequence of numbers: 0, 1, 1, 2, 3, 5 and so on, each number after 0 and 1 equaling the sum of the two before it. The Fibonacci sequence is closely connected to the “golden ratio” used in art and architecture and turns up frequently in mathematics and nature.

For Devlin, NPR’s “Math Guy,” Leonardo of Pisa is much more:  he’s the man who brought arithmetic to the West — a celebrity of 13th century Italy.
