The international best-seller that makes mathematics a thrilling exploration In twelve dreams, Robert, a boy who hates math, meets a Number Devil, who leads him to discover the amazing world of numbers: infinite numbers, prime numbers, Fibonacci numbers, numbers that magically appear in triangles, and numbers that expand without . As we dream with him, we are taken further and further into mathematical theory, where ideas eventually take flight, until everyone-from those who fumble over fractions to those who solve complex equations in their heads-winds up marveling at what numbers can do. Hans Magnus Enzensberger is a true polymath, the kind of superb intellectual who loves thinking and marshals all of his charm and wit to share his passions with the world. In The Number Devil, he brings together the surreal logic of Alice in Wonderland and the existential geometry of Flatland with the kind of math everyone would love, if only they had a number devil to teach it to them.

2011 Retailers Choice Award winner! Rebecca never felt safe as a child. In 1969, her father, Robert Nichols, moved to Sellerstown, North Carolina, to serve as a pastor. There he found a small community eager to welcome him—with one exception. Glaring at him from pew number seven was a man obsessed with controlling the church. Determined to get rid of anyone who stood in his way, he unleashed a plan of terror that was more devastating and violent than the Nichols family could have ever imagined. Refusing to be driven away by acts of intimidation, Rebecca’s father stood his ground until one night when an armed man walked into the family’s kitchen . . . And Rebecca’s life was shattered. If anyone had a reason to harbor hatred and seek personal revenge, it would be Rebecca. Yet The Devil in Pew Number Seven tells a different story. It is the amazing true saga of relentless persecution, one family’s faith and courage in the face of it, and a daughter whose parents taught her the power of forgiveness.

This witty introduction to number theory deals with the properties of numbers and numbers as abstract concepts. Topics include primes, divisibility, quadratic forms, and related theorems.
