"Khayyam" and "Omar Khayyam" redirect here. Omar Khayyám ( ), (born 18 May 1048 AD, Neyshapur , Iran —1131 AD, Neyshapur , Iran ), was a Persian polymath , mathematician , philosopher , astronomer , physician , and poet . He wrote treatises on mechanics , geography , and music . He became established as one of the major mathematicians and astronomers of the medieval period. Recognized as the author of the most important treatise on algebra before modern times as reflected in his Treatise on Demonstration of Problems of Algebra giving a geometric method for solving cubic equations by intersecting a hyperbola with a circle . He contributed to the calendar reform and may have proposed a heliocentric theory well before Copernicus . 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. Zamakhshari referred to him as “the philosopher of the world”. Many sources have testified that he taught for decades the philosophy of Ibn Sina in Nishapur where Khayyám lived most of his life, died, and was buried and where his mausoleum remains today a masterpiece of Iranian architecture visited by many people every year. Outside Iran and Persian speaking countries, Khayyám has had impact on literature and societies through translation and works of scholars. The greatest such impact among several others was in English-speaking countries; the English scholar Thomas Hyde (1636–1703) was the first non-Persian to study him. The most influential of all was Edward FitzGerald (1809–83) , who made Khayyám the most famous poet of the East in the West through his celebrated translation and adaptations of Khayyám's rather small number of quatrains ( rubaiyaa s) in Rubáiyát of Omar Khayyám .

He also wrote treatises on mechanics , geography , mineralogy and music . Born in Nishapur , in northeastern Iran also known as Persia, 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 (1070), 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. His mausoleum there remains a masterpiece of Iranian architecture visited by many people every year. Outside Iran and Persian-speaking countries, Khayyám has had an impact on literature and societies through the translation of his works and popularization by other scholars. The greatest such impact was in English-speaking countries; the English scholar Thomas Hyde (1636–1703) was the first non-Persian to study him. The most influential of all was Edward FitzGerald (1809–83), who made Khayyám the most famous poet of the East in the West through his celebrated translation and adaptations of Khayyám's rather small number of quatrains ( rubāʿiyāt ) in the Rubaiyat of Omar Khayyam . Omar Khayyám died in 1131 and is buried in the Khayyám Garden in Nishapur .

He was born in Nishabur , in northeastern Iran , and spent most of his life near the court of the Karakhanid and Seljuq rulers in the period which witnessed the First Crusade . As a mathematician, he is most notable for his work on the classification and solution of cubic equations , where he provided geometric solutions by the intersection of conics . Khayyam also contributed to the understanding of the parallel axiom . As an astronomer, he designed the Jalali calendar , a solar calendar with a very precise 33-year intercalation cycle . There is a tradition of attributing poetry to Omar Khayyam, written in the form of quatrains ( rubāʿiyāt رباعیات ).
