Ghiyāth ad-Dīn Abu'l-Fatḥ ʿUmar ibn Ibrāhīm al-Khayyām Nīshāpūrī, commonly known as Omar Khayyám, was a sufi mystic, Persian polymath, philosopher, mathematician, astronomer and poet. He also wrote treatises on mechanics, geography, mineralogy, music, and Islamic theology.

Born in Nishapur in North Eastern Iran, at a young age he moved to Samarkand and obtained his education there. Afterwards he moved to Bukhara and became established as one of the major mathematicians and astronomers of the medieval period. He is the author of one of the most important treatises on algebra written before modern times, the Treatise on Demonstration of Problems of Algebra, which includes a geometric method for solving cubic equations by intersecting a hyperbola with a circle. He contributed to a calendar reform.

His significance as a philosopher and teacher, and his few remaining philosophical works, have not received the same attention as his scientific and poetic writings. Al-Zamakhshari referred to him as “the philosopher of the world”. He taught the philosophy of Avicenna for decades in Nishapur, where Khayyám was born and buried.
