Omar Khayyam is remembered with a Google Doodle (Google) ( ) Omar Khayyam, a celebrated Persian mathematician, astronomer, philosopher and poet, is being remembered with a Google Doodle on his 971st birthday. Born in the town of Nishapur in what is now Iran in 1048, Khayyam is most commonly recognised for both his astronomical expertise, which led to the reform of the calendar, and his poetry. Having studied under scholars including Sheik Muhammand Mansuri and then the imam Mowaffaq Nishapuri, Khayyam made great strides in both mathematics and astronomy during his lifetime. At the age of 22, Khayyam was already making a name for himself in the field of mathematics through the publication of Treatise on Demonstration of Problems of Algebra and Balancing . In the text, Khayyam explained his observation that cubic equations can have multiple solutions, as well as his methods for solving quadratic equations.
