Google derived its name from the word "googol", a term coined by then nine-year-old Milton Sirotta, nephew of the American mathematician Edward Kasner. The story goes, Kasner had asked his nephew to invent a name for a very large number - ten to the power of one hundred (the numeral one followed by 100 zeros), and Milton called it a googol. The term was later made popular and in Kasner's book, Mathematics and the Imagination, which he co-authored with James Newman. Later, another mathematician invented the term "googolplex", which represents ten to the power of a googol - a substantially larger number.
As Google is now the world's most popular search engine, its association with a number so vast is appropriate. According to www.google.com, "Google's use of the term [Google] reflects the company's mission to organize the immense, seemingly infinite amount of information available on the web."* In fact, this mission itself grows increasingly large daily, as the Internet continues to grow exponentially throughout the world.
