Could you please give me a couple of examples of when you MATH guys would use a google. Do youu measure, like, galaxies with it ? Or was it created to keep track of Mr Gate's bank account.

Cheers Kevin

The only place where I have seen a googol used is in comparing the size of some "large" numbers. A googol is 10¹⁰⁰, that is 1 followed by 100 zeros. I don't know how many galaxies there are but I do know it is considerably less than a googol. The one number that I was able to find for you that might help with the size of a googol is that if the entire universe were filled with protons and electrons, leaving no empty space between them, the total number of electrons and protons used would be 10¹¹⁰. The number appears in the article by Edward Kasner and James R. Newman, referenced in Large Numbers, an answer given by Chris to a previous question. If you can find this article I am sure that you would enjoy reading it.
