Timeline of Muhammad ibn Musa al-Khwarizmi, Persian polymath at the House of Wisdom whose works 'The Compendious Book on Calculation by Completion and Balancing' and on Hindu-Arabic numerals gave rise to algebra and algorithms, shaping mathematics and computing.
Muhammad ibn Musa al-Khwarizmi is born in the region of Khwarazm (modern-day Khiva, Uzbekistan). His early life is not well documented, but he likely received a strong education in mathematics, astronomy, and geography. #mathematics #history
Al-Khwarizmi moves to Baghdad, the capital of the Abbasid Caliphate, which was a center of learning and culture. He joins the House of Wisdom (Bayt al-Hikma), a premier academy and library. #history #islamicgoldenage
Caliph al-Ma'mun becomes the patron of the House of Wisdom, commissioning translations and scientific works. Al-Khwarizmi flourishes under his patronage, producing many of his major works. #history #science
Al-Khwarizmi completes his astronomical tables (Zij al-Sindhind), based on Indian and Greek sources. These tables were used for centuries in the Islamic world and later translated into Latin. #astronomy #mathematics
Al-Khwarizmi introduces the method of 'al-jabr' (completion) to solve equations by adding equal terms to both sides, creating a systematic approach to algebra. #algebra #mathematics
Al-Khwarizmi completes 'The Compendious Book on Calculation by Completion and Balancing' (Al-Kitab al-mukhtasar fi hisab al-jabr wa'l-muqabala), which introduces systematic algebraic methods. The term 'algebra' derives from 'al-jabr' in the title. #algebra #mathematics
Al-Khwarizmi translates the Indian astronomical work 'Sindhind' (from Sanskrit Siddhanta) into Arabic, incorporating Indian astronomy into Islamic science. This work later influences European astronomy. #astronomy #science
Al-Khwarizmi writes a treatise explaining the Hindu-Arabic numeral system, including zero and place value. This work, though now lost in Arabic, survives in Latin translation as 'Algoritmi de numero Indorum', popularizing the system in Europe. #mathematics #numerals
Al-Khwarizmi explains the use of zero as a placeholder in the Hindu numeral system, which was critical for the development of decimal arithmetic. #mathematics #numerals
Al-Khwarizmi participates in a project sponsored by al-Ma'mun to measure the Earth's circumference, using methods from Greek and Indian astronomy. This demonstrated the advanced state of Islamic science. #geography #science
