Who was Ali Qushji?

Ala al-Dīn Ali ibn Muhammed, known as Ali Qushji was an astronomer, mathematician and physicist originally from Samarkand, who settled in the Ottoman Empire some time before 1472. As a disciple of Ulugh Beg, he is best known for the development of astronomical physics independent from natural philosophy, and for providing empirical evidence for the Earth's rotation in his treatise, Concerning the Supposed Dependence of Astronomy upon Philosophy. In addition to his contributions to Ulugh Beg's famous work Zij-i-Sultani and to the founding of Sahn-ı Seman University, one of the first madrasahs in the Ottoman Empire, Ali Qushji was also the author of several scientific works and textbooks on astronomy.
