May 18th marks the 971st anniversary of Omar Al Khayam (1048 – 1131), the prominent Iranian mathematician, astronomer, and poet whose anniversary is celebrated by Google on Saturday. <\/p>\n
Al Khayam\u2019s birth name is Ghiyath Al Din Abou Al Fath Omar bin Ibrahim El Khayam (Quatrains of Al Khayam). Much of his popularity is rooted in his poems known as Rubaiyat Al Khayam. His poetry reflects he adopted Sufism. <\/p>\n
As a mathematician, Al Khayam authored \u201cTreatise on Demonstration of Problems of Algebra\u201d where \u201che gave a systematic discussion of the solution of cubic equations by means of intersecting conic sections,\u201d according to Britannica. <\/p>\n
Al Khayam also discovered how to extract nth roots of numbers for arbitrary whole numbers n. He was tasked by the Seljuk Sultan Malik Shah to assume astronomical observations necessary for the reform of the calendar. His efforts gave rise to the Jal\u0101l\u012b calendar, which is a solar calendar, based on making eight of every 33 years leap years. <\/p>\n
Al Khayam also produced the theory of proportion, and fundamental critiques of Euclid\u2019s theory of parallels. The theory of proportion suggests enlarging the notion of number to include ratios of magnitudes. <\/p>\n
Al Khayam was the student of Father of Medicine Ibn Sina known in the West as Avicenna. His childhood friends were scholar and vizier of the Seljuk Empire, Nizam al-Mulk, and founder of the Assassins Order, Hassan-e Sabb\u0101h. <\/p>\n
