Nasir al-Din al-Tusi
Muhammad ibn Muhammad ibn al-Hasan al-Tusi (1201 – 1274),}} also known as
Nasir al-Din al-Tusi (; ) or simply as
(al-)Tusi, was a
Persian polymath, architect,
philosopher,
physician,
scientist, and
theologian. Nasir al-Din al-Tusi was a well published author, writing on subjects of math, engineering,
prose, and mysticism. Additionally, al-Tusi made several scientific advancements. In
astronomy, al-Tusi created very accurate tables of
planetary motion, an updated planetary model, and critiques of
Ptolemaic astronomy. He also made strides in
logic, mathematics but especially trigonometry, biology, and chemistry. Nasir al-Din al-Tusi left behind a great legacy as well. Tusi is widely regarded as one of the greatest scientists of medieval Islam, since he is often considered the creator of
trigonometry as a mathematical discipline in its own right. The Muslim scholar
Ibn Khaldun (1332–1406) considered Tusi to be the greatest of the later Persian scholars. There is also reason to believe that he may have influenced
Copernican heliocentrism.
