Al-Tusi

Al-Tusi was a 13th-century Persian mathematician, astronomer, and philosopher known for his significant contributions to astronomy and trigonometry. He developed the Tusi Couple, a mathematical model that explained the future motion of planets without requiring epicycles, influencing later Copernican astronomy. His work helped advance accurate astronomical charts and understanding of planetary motion. Al-Tusi's innovations bridged Persian and Islamic scientific traditions and laid groundwork that would later influence European science, making him a key figure in the history of science and mathematics.
