googol

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.

googol (n.)

number represented by 1 followed by 100 zeroes, 1940, in "Mathematics and the Imagination," a layman's book on mathematics written by U.S. mathematicians Edward Kasner (1878-1955) and James R. Newman, the word supposedly coined a year or two before by Kasner's 9- (or 8-) year-old nephew (unnamed in the book's account of the event), when asked for a name for an enormous number. Perhaps influenced by comic strip character Barney Google. Googolplex (10 to the power of a googol) coined at the same time, in the same way, with plex.

googol：大数，10的100次方

据说是来自19世纪美国数学家Edward Kasner的侄子创造的词。Kasner希望为10的100次方取一个好名字，苦思不得其解，开玩笑问他侄子，他侄子正沉迷于漫画小说人物Barney Google, 就建议叫googol. 于是，一个新词就诞生了。从某种程度上也反映出取名字的严肃和随意双重性，当想不出一个好名字的时候，很可能就随便取个名字。比较guillotine.

googol：天文数字，古戈尔，10的100次方

这是一个巨大的数字，1后面100个“0”。它是美国哥伦比亚大学数学教授爱德华·卡斯纳（Edward Kasner，1878—1955）根据他的小侄子富于幽默的提议杜撰的新词。

在googol的基础上，又有人造出了更大的数字googolplex，即“10的古戈尔次方”(1后面带10的100次方个零的数字)，这是一个相当大的数字。-plex是duplex的简写，意思是“加倍的”“双重的”。从10的100次方到10的古戈尔次方在数学上又叫“googol群”。
