Why is ‘x’ the unknown? by Terry Moore

Summary Why is ‘x’ the unknown? by Terry Moore

He has the answer to a question that all we have.  Why is it that letter X represent the unknown?
He said, its everywhere in the Culture: X prize, X files, Project X, Tdex? And finally we finalizes the introduction with a one single question: Where would that come from?
Six years ago, he decides that he would learn Arabic, which is the supremely logical language, namely each word, sentences or phrase is like crafting a equation, since every part is extremely precise.
That is one of the reason that so much of knowledge that we identificated as Western science is originally from the first centuries by Persians, Arabs and Turks. This include a little system called al-jebra, as knows as “the system for reconciling disparate parts”. Posterior, Al-jebr came into English as algebra. When the Arabic texts arrived in the 11th and 12th century, specifically Spain, they were tremendous interest in translation this wisdom into a European language.
But they had two problems, namely, complex of Arabic language and Arabic sound without equivalences in European Language. One of the culprits is the letter SH, it sounds like SH. And it’s also the very first letter of the word shalan, which means “something” just the English word something, something undefined, unknown thing.
When they started with the translation of the material, they found the word shalan, and can’t be rendered into Spanish because Spanish doesn’t have that SH, that “sh” sound. So by convention, they created a rule in which they borrowed the CK sound, “ck” sound, from the classical Greek in the form of the letter Kai.
Later when this material was translated into a common European language, which is to say Latin, they simply replaced the Greek Kai with the Latin X. And once that happened, once this material was in Latin, it formed the basis for mathematics textbooks for almost 600 years.

            He said: Now, we have the answer to our question. Why is it that X is the unknown? X is the unknown because you can’t say “sh” in Spanish.
