At the age of four, he could ask you when you were born and then calculate the number of seconds you had been alive in his head. But he didn't learn to butter his own bread until he turned twenty. Instead, he traveled around the world, from one mathematician to the next, collaborating on an astonishing number of publications. With a simple, lyrical text and richly layered illustrations, this is a beautiful introduction to the world of math and a fascinating look at the unique character traits that made "Uncle Paul" a great man.

    The Last Little Cat is now back in print to delight both children and adults. The last little cat was born in a kennel, surrounded by dogs and dog cages and dog noises. The little cat was always half cold and half hungry - until the day it fell into the cage of the old, blind dog. Then, for a while, the last little cat was warm, and the last little cat was well fed. But how could such a small cat know that barn doors are closed at night and that there are people in the world who do not want to help a helpless kitten? This story of how the last little cat found a home, and not only a home, but the perfect home, again confirms DeJong's place among the finest writers of this or any day.
