A Treatise on Drawing Chords in a Circle
Abu al-Rayhan al-Biruni (also known by the Latinized version of his name, Alberonius, 973–1048 AD; 362–440 AH) was an 11th-century Muslim polymath whose works and scholarly interests spanned the physical and natural sciences, mathematics, astronomy, geography, history, chronology, and linguistics. Al-Biruni was born in Kath, Khuwarazm, in present-day Uzbekistan, and died in Ghazni, in what is today east-central Afghanistan. He wrote more than 120 works and is considered the founder of Indology for his detailed description of 11th-century India. The crater Al-Biruni on the moon is named after him. Risālah fī Istikhrāj al-awtār fī al-dāʼirah (A treatise on drawing chords in a circle) is, as its title suggests, a treatise on geometry that deals with circles.
