It is said that the number is an expression of the word Google. In fact, during a walk with his nephews Milton and Edwin, the mathematician Edward Kassner asked the two to suggest a name that sounded good for a very large number, just a 1 followed by 100 zeros, and Milton said "googol." Googol, which Kassner show clearly the ultimate limit of human imagination, was a source of inspiration for Brin and Page, who called their company Google.
