In 1940, the mathematician Edward Kasner published the book "Mathematics and the Imagination", in which he popularized the words googol and googolplex which his nephew suggested as names for big numbers. The number googol has been defined as 1 followed by a hundred zeros: googol = 10^100 = 10 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 The much larger number googolplex has been defined as 1 followed by a googol zeros. While this number can easily be written as googolplex = 10^googol = 10^(10^100) using the exponential notation, it has often been claimed that the number googolplex is so large that it can never be written out in full. However in this "Googolplex Written Out" series of books, I am doing just that. It consists out of 10 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 volumes, and each volume contains 1 000 000 zeros of the number googolplex. The first volume also contains the initial digit one with which googolplex starts. www.GoogolplexWrittenOut.com

Pippa and Troy are happy to help, especially when they get to ride to the North Pole in a spaceship. But when they return, Martin, the bully next door, sees something that he shouldn't.

In the American Mathematical Society's first-ever book for kids (and kids at heart), mathematician and author Richard Evan Schwartz leads math lovers of all ages on an innovative and strikingly illustrated journey through the infinite number system. By means of engaging, imaginative visuals and endearing narration, Schwartz manages the monumental task of presenting the complex concept of Big Numbers in fresh and relatable ways. The book begins with small, easily observable numbers before building up to truly gigantic ones, like a nonillion, a tredecillion, a googol, and even ones too huge for names! Any person, regardless of age, can benefit from reading this book. Readers will find themselves returning to its pages for a very long time, perpetually learning from and growing with the narrative as their knowledge deepens. Really Big Numbers is a wonderful enrichment for any math education program and is enthusiastically recommended to every teacher, parent and grandparent, student, child, or other individual interested in exploring the vast universe of numbers.
