Erikka Askeland (Perspective 30 March) rightly pours scorn on “trademark pedants” such as those emanating from the Googleplex campus.
As every schoolchild knows, the words “Google” and “Google-plex” are similar to the words “googol” and “googolplex”, words coined by American maths enthusiast Milton Sirotta in the 1920s. A googol is ten to the power of 100 – a number greater than the number of atoms in the universe. A googolplex is ten to the power of one googol. Possibly, Google has a googol reasons for defending its trade-mark, or it may be all a bit of a googly!
