Really interesting because in the Maltese language (which has Arabic routes) the letter 'X' is pronounced as 'Shh'!

Very inspiring information. While I was studying at high school, fistly my friend recommended this speech. When I watched, I liked very much.
One of the most short and enjoyable on TED so far.
I didn't know that. This story is so interesting!!!
But the good thing about this is that it helped us to make mathematics highly symbolic and therefore more simple to write complex things.

He didn't mention why Y is also used to be the symbol for unknown. The reason is because the word Shy = شيء contains the letter Y at the end so it was common to use X ans Y as symbols for unknown.

AFTER X, YOU CAN USE ANY ALPHABETS AS UNKNOWN. IF YOU HAVE 2 KIND OF UNKNOWN, YOU CAN'T USE X AND X, THEN THEY USED X AND Y, OR X AND Z ETC.
Very Interesting. It's Amazing what information you come across when you find the roots of words
Wow, I am Egyptian and I've learned all my life in English, but never knew the origin of the "x" symbol but now ! =)
I've sworn off TED videos until my exam was over but this was just too intriguing haha
Love my language
Vignesh Balaji, that's what Mr Terry Moore has explained: chi is a deformation of the arabic word "شيء" (which means "something") which is pronounced "chay'a" in arabic and deformed to "chi" for an easy pronunciation by spanish, so that's why they chose the grec letter "chi"
That build-up was brilliant
This was very interesting. I learned something new today!
This was great fun! Bravo!
'when you are around i wont show up' - music to my ears :)
great! I loved this information
this is fascinating. and that ending was so funny :-D
Great Video !! thanx 4 sharing
I like it when those Romans applause saying: Yeah 3:46
Terry Moore - You are brilliant
I barely understood that and still watched the whole thing. Sweet.
How could I live without this information?!
very nice!! simple questions very often have hard answers! My first language is Arabic and I didn't thought that this the reason behind using 'x' as the unknown is the word "شيئ" which means 'something" in english. I thought the reason behind that is we use a letter in Arabic that similar to 'x' in english alphabet which is the letter "س". In middle school, we always used "س" as the unknown. I think the use of the letter "س" Arabic mathematics came from 17th century english math. I'm not sure.
Really funny. Never expected this to come my way...
Lovely lecture
شكرا جزيلا
I like the tl;dr version of the talk he gives at the end.
I'm fluent in Arabic! But I grew up mostly in Kansas. This is awesome!
very neat, organized and interesting reasoning !!

Most of these translations were made in a monastery in Ripoll. Monks from Ripoll used to spoke many languages, but their common language was Catalan, not Spanish. In Catalan we pronounce the letter X exactly as SH is pronouced in English.

What I am suggesting is that that very same degree you mentioned is a compilation of accomplishments of past individuals. That in their turn would build on top of others. But I do see your point. Pride is not the best suitable feeling towards our cultural ancestors. Perhaps admiration and inspiration would be more fit. Even so the feeling of admiration for the deeds of the group one considers oneself to be part is perfectly compatible with one of the meanings of Pride. Correct me if I'm wrong.
Great talk.
The older form of Spanish used the letter X to spell the sh sound (as is still done in the Portuguese and Catalan languages). This is why Spanish-America is peppered with place names spelled with X (such as Xochimilco). The letter X eventually began to be pronounced as either J or S (and often respelled to reflect that fact). That is why, for instance, in Spanish the names Javier and Xavier are both seen to this day, while only the form with the X is used in Portuguese and Catalan.

Yes, I've always wondered about that!
Spanish letter "x" was also used to transcribe "sh" sounds in native Mexican words.
Thank you

The letter is just a symbol to say "I don't know what this number is right now". You can do all the same math with it as you did numbers, because it is a number itself that you simply don't know yet.

Not world changing but a it's pretty curious question answered. I like it.
Curiously the sound "sh" later made it into Spanish, at least in some parts of Argentina, Uruguay ("y", "ll") and Mexico ("ch").
You make some very good points. Being proud just because you're here is silly.
so helpfull thank you

Arabic is really logical when it comes to the grammar. But when it comes to the poems, one can easily make grammar mistakes for the poem to rhyme. There are also many exceptions in grammar, for some words don't look "nice" if they are written according to the grammar. Some logical and at the same time illogical stuff also exists. For example, Arabic has "the plural of the plural." I'm really glad that I learned it when I was only a kid.
very very nice ...
we CAN say SH in spanish: in Argentina we replace the Y or the LL for the sound of the Y. It is just in a region of the country
