Googol

Googol is a large number, equal to $$10^{100}$$ or 1 followed by 100 zeroes. It was coined by Edward Kasner's nine-year-old nephew, Milton Sirotta. The name appears to have no particular meaning.

The googol's decimal expansion is shown below.

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 googol, in the American system, is equal to ten duotrigintillion, or ten sexdecilliard in the French/German system.

Larry Page and Sergey Brin, the founders of the Google search engine, named their company after a pun on googol, as their goal is to cache the mass of data that makes up the World Wide Web.
