googol: [20] There are comparatively few ‘new’ words in the English language – that is, words which have not been made up from combinations of old words, or borrowed from other languages, but have sprung up as entirely new growths – but this is one of them. When in the 1930s the American mathematician Dr Edward Kasner was trying to think of a name for an unimaginably large number, ten to the power of a hundred, he asked his nine-year-old nephew Milton Serotta for a suggestion, and googol was what he got. It has never really caught on in technical use, although it has spawned a compound of its own – the googolplex, ten to the power of a googol.
