He made major findings in the fields of astronomy and trigonometry, years before anyone even thought of them. He was instrumental in establishing one of the largest astronomical observatories in the Islamic world, situated in Maragha, modern-day Azerbaijan. He is known for introducing astronomical tables for planetary movements, which were used by astrologers in the coming years. He started writing as a student and went on to become a talented and learned intellectual. His journey of discovering and researching on a variety of subjects began when he was captured and hired as a scientific advisor by Mongol leader Hulagu Khan.
