He is best known for his poetry, and outside Iran, for the quatrains (rubaiyaas) in Rubaiyat of Omar Khayyam, popularized through Edward Fitzgerald‘s re-created translation. His substantial mathematical contributions include his Treatise on Demonstration of Problems of Algebra, which gives a geometric method for solving cubic equations by intersecting a hyperbola with a circle. He also contributed to calendar reform and may have proposed a heliocentric theory well before Copernicus. ” ( Wikipedia )
