Definition googolplex

Etymology

googol +‎ -plex. Like the word googol, googolplex was coined in 1920 by the nine-year-old Milton Sirotta (1911–1981), the nephew of American mathematician Edward Kasner (1878–1955). The word was first published and precisely defined in the book Mathematics and the Imagination (1940) by Kasner and fellow mathematician James R. Newman (1907–1966) (see the quotation below).
