علم ایرانی — ریاضیدانان، ستارهشناسان و پزشکانی که جهان را تغییر دادند
During the 8th-13th century Islamic Golden Age, Persian intellectuals dominated every field of science and learning. Muhammad ibn Musa al-Khwarizmi (c. 780–850), from Khwarazm (modern Uzbekistan), wrote Al-Kitab al-Mukhtasar fi Hisab al-Jabr — the text that gave algebra its name (al-jabr → algebra) and algorithm its name (al-Khwarizmi → algorithm).
Abu Rayhan Biruni (973–1048) was perhaps the greatest scholar of the medieval world — he mastered astronomy, mathematics, physics, geography, mineralogy, and anthropology. He calculated the Earth's radius with remarkable accuracy (within 0.5% of the modern value) using a new geometric method. His study of India (Kitab al-Hind) is still a standard reference for medieval Indian civilization.
Nasir al-Din Tusi (1201–1274) reformed Ptolemaic astronomy with the 'Tusi couple' — a geometric model that directly influenced Copernicus. Tusi also created the first trigonometry textbook treating trig as an independent discipline from astronomy. These Persian scientists didn't just transmit Greek knowledge to Europe — they fundamentally transformed it.
Al-Khwarizmi, a Persian mathematician from Khwarazm, wrote the book that gave algebra its name (from 'al-jabr' in the title). He also gave us the word 'algorithm' from his own name. He is considered the father of algebra.
Abu Rayhan Biruni (973–1048) was a Persian polymath who made major contributions to astronomy, mathematics, physics, geography, and anthropology. He accurately calculated the Earth's radius and conducted one of the most thorough studies of Indian civilization in the medieval world.
