Google Search Operators
Googol is the name that is given to the number 10100 (the digit 1 followed by one hundred zeros).
Nine-year-old Milton Sirotta (1911-1981), nephew of North American mathematician Edward Kasner, coined the term in 1920.
The name Google has been derived from the word "Googol" and has been spelled wrong by the founders Larry Page and Sergey Brin (as published in the book "The Google Story" by David A. Vise).
Google is the most used search engine on the web (perhaps, there is still somebody who doesn't know it...).
