Googol and google.

In 1940, the American mathematician Dr Edward Kasner (1878-1955) defined the "googol". The name for this very large number was suggested by his nine year old nephew, Milton.

1 googol = 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

That is: 1 googol = [10.sup.100]

Kasner also defined a much larger number, the googolplex, which is 1 followed by a googol of zeros.

1 googolplex = [10.sup.google]

This number is so enormous that if the Earth was a paper sphere there would not be enough room to write the number in full on its surface. In fact if all the planets and stars in the universe were made of paper there would still not be enough room!

The name of the Internet giant Google originated from a misspelling of "googol". "Googleplex" is the name of Google's company headquarters in California.
