The history stretching back to more than 2000 years, Khiva the city of Uzbekistan is a word heritage. Site packed full with the remains of palaces, mosques and mausoleums from the city’s Silk Road heyday.
Khiva was no exception and Central Asia was a world center of learning for centuries. Abū ‘Abdallāh Muḥammad ibn Mūsā Al-Khwārizm, a Persian scholar born around 780.
He is sometimes called the “grandfather of computer science” and is believed to have invented algebra and the decimal point. In fact, the word “algebra” comes from his algebraic mathematical treatise, called Hisab al-Jabr w’al-muqabala (The Compendious Book on Calculation by Completion and Balancing).
“Algebra” is derived from al-jabr, one of the two operations he used to solve quadratic equations. Algorism and algorithm stem from Algoritmi, the Latin form of his name. His name is also the origin of (Spanish) guarismo and of (Portuguese) algarismo, both meaning digit.
Al-Khwārizmī’s Zīj al-Sindhind also contained tables for the trigonometric functions of sines and cosine. A related treatise on spherical trigonometry is also attributed to him.
