In Googol English. We usually say guguel. In math it is a hugely large number, named after a nine-year-old nephew of mathematician Edward Kasner in 1938. Initially he applied it to 1 followed by as many zeros as you want until you got tired, but finally it materialized in a 1 followed by a hundred zeros, that is, ten to one hundred, more or less factorial of 70 ( 70!) . The mathematician wanted to illustrate the difference between an unimaginably large number and infinity. It is said that the founders of Google made a typo when writing the name of their search engine and there we are.
