Nasir al-Din al-Tusi (astronomer)

Nasir al-Din al-Tusi was a 13th-century Persian scholar renowned for his pioneering work in astronomy and mathematics. He improved existing models of planetary motion, creating more accurate astronomical tables and a geometric model called the "Tusi Couple" that influenced future scientists. Al-Tusi also contributed to trigonometry and developed techniques for calculating celestial positions. His work helped bridge Greek, Indian, and Islamic scientific traditions, significantly advancing the understanding of the cosmos during the medieval Islamic Golden Age. His innovations laid the groundwork for later astronomers, including those in Europe, shaping the development of modern astronomy.
