From the Ted Talk by Terry Moore: Why is 'x' the unknown?

Unscramble the Blue Letters

I have the answer to a question that we've all asked. The question is, Why is it that the letter X represents the unknown? Now I know we leaenrd that in math class, but now it's everywhere in the culture — The X prize, the X-Files, Project X, TEDx. Where'd that come from?.
About six years ago I decided that I would lraen Arabic, which truns out to be a supremely logical language. To write a word or a phrase or a sentence in Arabic is like crafting an eatquion, because every part is extremely precise and caeirrs a lot of information. That's one of the resanos so much of what we've come to think of as Western science and mathematics and engineering was really werokd out in the first few centuries of the Common Era by the Persians and the Arabs and the Turks.

About six years ago I decided that I would learn Arabic, which turns out to be a supremely logical language. To write a word or a phrase or a sentence in Arabic is like crafting an equation, because every part is extremely precise and carries a lot of information. That's one of the reasons so much of what we've come to think of as Western science and mathematics and engineering was really worked out in the first few centuries of the Common Era by the Persians and the Arabs and the Turks.
