Heres an except from The Google Site: http://www.google.com/corporate/history.html
Google is a play on the word googol, which was coined by Milton Sirotta, nephew of American mathematician Edward Kasner, and was popularized in the book, Mathematics and the Imagination by Kasner and James Newman. It refers to the number represented by the numeral 1 followed by 100 zeros. Google's use of the term reflects the company's mission to organize the immense, seemingly infinite amount of information available on the web."
This gets even better! Enjoy!
