This is my favorite Ted talk that I could watch over and over again. It shows that you could share so much in just 3:57 minutes. In this video, Terry Moore briefly shares with us on the history of knowledge transfer from the Arabs to the Europeans through the translation of Arabic texts containing the algebra equations (Al-Jebr mainly by Al-Khawarizmi) by the Spanish in the 11th – 12th centuries. So why is ‘x’ the unknown? It’s because you can’t say ‘sh’ in Spanish!
P/s: I miss maths, science and the lab!
