The Pleasures of Pi, E

This is a mathematics book written specifically for the enjoyment of non-mathematicians and those who "hated math in school." The book is organized into two sections: (I) Beauty for the Eye (shallow water for the non-swimmer); and (II) A Feast for the Mind (slowly getting deeper for the more adventurous).The author covers beautiful infinite series beginning with those that a young child can understand to one that even Isaac Newton, Gottfried Liebniz and the famous Bernoulli brothers could not sum.
