From Wikipedia, the free encyclopedia
Qāḍī Zāda al-Rūmī (1364 in Bursa, Turkey – 1436 in Samarkand, Uzbekistan), whose actual name was Salah al-Din Musa Pasha (Qāḍī Zāda means "son of the judge"), was an astronomer and mathematician who worked at the observatory in Samarkand. He computed sin 1° to an accuracy of 10-12.
Together with Ulugh Beg, al-Kāshī and a few other astronomers he produced the Zij-i Sultani, the first comprehensive stellar catalogue since Ptolomy, containing the positions of 992 stars.
