Another one of those phrases you catch on the discovery channel :
“googol”
“a unit of quantity equal to 10^100 (1 followed by 100 zeroes). The googol was invented by the American mathematician Edward Kasner (1878-1955) in 1938. According to the story, Kasner asked his nephew Milton Sirotta, who was then 8 years old, what name he would give to a really large number, and “googol” was Milton’s response. Kasner also defined the googolplex, equal to 10^googol, that is, 1 followed by a googol of zeroes. These inventions caught the public’s fancy and are often mentioned in discussions of very large numbers.”
