Iranian contributions to math and science

Introduction to the work of Mirzakhani



Iran Khayyam - Part 1 of 8 "Intoxicating Rhymes & Sobering Wine" A Documentary about Omar Khayyam





The Persian astronomer, mathematician, and poet Omar Khayyam (1048-ca. 1132) made important contributions to mathematics, but his chief claim to fame, at least in the last 100 years, has been as the author of a collection of quatrains, the "Rubaiyat." Omar Khayyam was born in Nishapur in May 1048.




Kharazmi - The father of algebra Kharazmi 


Kharazmi's contributions to mathematics, geography, astronomy, and cartography established the basis for innovation in algebra and trigonometry. His systematic approach to solving linear and quadratic equations led to algebra, a word derived from the title of his book on the subject, "The Compendious Book on Calculation by Completion and Balancing".[sup][27][/sup]On the Calculation with Hindu Numerals written about 820, was principally responsible for spreading the Hindu–Arabic numeral system throughout the Middle East and Europe. It was translated into Latin as Algoritmi de numero Indorum. Al-Khwārizmī, rendered as (Latin) Algoritmi, led to the term "algorithm".Some of his work was based on Persian and Babylonian astronomy, Indian numbers, and Greek mathematics.Kharazmi systematized and corrected Ptolemy's data for Africa and the Middle East. Another major book was Kitab surat al-ard ("The Image of the Earth"; translated as Geography), presenting the coordinates of places based on those in the Geography of Ptolemy but with improved values for the Mediterranean Sea, Asia, and Africa.[sup][citation needed][/sup]He also wrote on mechanical devices like the astrolabe and sundial.He assisted a project to determine the circumference of the Earth and in making a world map for al-Ma'mun, the caliph, overseeing 70 geographers.[sup][28][/sup]When, in the 12th century, his works spread to Europe through Latin translations, it had a profound impact on the advance of mathematics in Europe.[sup][citation needed][/sup]
