Title: Mathematics and the Imagination
Authors: Edward Kasner and James Newman
Short Description: A number of chapters covering lots of subjects: counting numbers (including the coining of the word "googol"); $pi$, \pi$, $i$, and $e$; geometries, plane and "fancy" ("Lobachevsky's Eiffel Towers and Riemann's Holland Tunnels"); puzzles; paradoxes; chance and probability; topology ("rubber sheet geometry"); calculus. Very much in the spirit of Martin Gardner columns, but from before they existed (the book was originally published in 1940; Gardner began writing his columns in 1956).
