A googol is 10^100

A googolplex is 10^googol

I've never heard of a googolplexian!

Ok. I have now! See: http://www.googolplexian.com/

A googolplexian is 10^googolplex

The term "googol" was coined in 1938 by 9-year-old Milton Sirotta, nephew of Edward Kasner - see the book Mathematics and the Imagination by Kasner and Newman. (It's a good book - published in 1940, it's still worth reading today.)

To get an idea of how large a "googol" is, let's suppose that we could write out one billion zeroes per second.

Now, one billion seconds is about 31.7 years......and let's suppose that we lived for three billion seconds, or about 95 years. And let's suppose that we started writing our zeroes at birth and never took a break for our entire lifetime !!!

Then the number of zeroes that we could write is (3 x 10^{9} x 10^{9} ) = (3 x 10^{18})

So the number of "lifetimes" that would be required for us to complete the job is, approximately............ (10^{100} ) / [3 x 10^{18} ] = about [3.33 x 10^{82}] "lifetimes"
