The word "googol" is a mathematical term that refers to 10 to the power of 100, or a one followed by 100 zeroes. Its spelling is derived from its creator, American mathematician Edward Kasner, who asked his nine-year-old nephew to come up with a name for this enormous number. The boy reportedly suggested "googol," which Kasner found amusing and adopted. The word is pronounced /ˈɡuːɡəl/ (GOO-gəl) and should not be confused with "Google," the popular search engine.
The word "googol" was coined by the mathematician Edward Kasner in 1920. He named it as a playful term for the number represented by a 1 followed by 100 zeros (10^100). The word "googol" is derived from the word "googolplex", which Kasner also coined, representing an even larger number—a 1 followed by a googol of zeros (10^(10^100)). Kasner's intention was to create a name for an unimaginably large number, and he reportedly asked his nine-year-old nephew, Milton Sirotta, to come up with a name. The term "googol" caught on and eventually led to the creation of the famous search engine company, Google, which was named as a play on words.
