People living in different places invent different words for things, and then the words control how they think. The Masai people, for instance, do not have a word that means 'the future.' Therefore, when they talk of time, they always talk about the present time.Hope, for example, lives in the future. The things one hopes for are always things in the future. So the Masai people may never have felt hope, since they have no idea of a future.But, if the Masai live without hope, they also live without fear. For fear is always about the future, too.-Herr Winteler

Maxwell's theory of electromagnetism is generally studied only by advanced students of physics, but Albert had mastered it by the time he was sixteen years old.
