Muhammad ibn Musa al-Khwarizmi (c. 780–850) was a Persian mathematician, astronomer, and geographer who worked in the House of Wisdom in Baghdad during the Islamic Golden Age. He is best known for his contributions to algebra, introducing systematic methods for solving linear and quadratic equations in his book Al-Kitab al-Mukhtasar fi Hisab al-Jabr wal-Muqabala, which gave rise to the term "algebra." His work also played a key role in popularizing Hindu-Arabic numerals and decimal notation in the Islamic world and Europe. The term "algorithm" is derived from his name, reflecting his influence on mathematical computation. Al-Khwarizmi, designed by A. Adashev, combined photogravure and engraved and issued by the USSR on September 6, 1983 to mark the 1200th birth anniversary of Al-Khwarizmi.  |
