.. Omar Khayyam
Ghiyath al-Din Abu al-Futuh Omar bin Ibrahim bin Salih al-Khayyam al-Naysaburi (May 18, 1048 – December 4, 1131), known as Omar Khayyam (Khayyam is his father’s surname, as he worked in making tents), was a Persian Muslim astronomer, mathematician, philosopher, and poet, born in the city of Nishapur, Khorasan. , Iran between 1038 and 1048 AD, and he died there between 1123 and 1124 AD, when he was 83 years old. He specialized in mathematics, astronomy, language, jurisprudence, and history. He was the first to invent the method of calculating trigonometry and third-degree algebraic equations using conic sections, and he is the author of the famous quadrilaterals.
Omar Khayyam, whose biography they tampered with and emptied of his status through an act
He is the author of the Quatrains of Khayyam, and the first to translate them were the British, and then the poet Ahmed Rami. He is a great mathematician and the author of trigonometry. Historians consider Omar Khayyam a pioneer in the invention of analytical geometry about five centuries before René Descartes.
He was the first to use the Arabic word “something,” which was repeated in the Holy Qur’an. Khayyam used it to refer to the word that was depicted in Portuguese scientific books (Xay), and it was soon replaced gradually by its first letter, “x,” which became a global symbol for the unknown number.
This is in addition to his genius contributions to astronomy and the establishment of a highly accurate annual calendar. Historian George Sarton says that Khayyam’s calendar was more accurate than the Gregorian calendar.
His fame is due to his work in mathematics, where he solved second degree equations using geometric and algebraic methods. He also organized cubic equations and tried to solve them all, arriving at partial geometric solutions for most of them. He investigated the binomial theorem when the integer exponent is positive, and developed methods for finding specific density.
Omar Khayyam also excelled in astronomy. Sultan Malikshah asked him in the year 467 AH/1074 AD to establish an observatory in the city of Isfahan. He was also asked to modify the old Persian calendar. Historian George Sarton says that Khayyam's calendar was more accurate than the Gregorian calendar. Khayyam made a very precise annual calendar, and he monitored at the Isfahan Observatory.
.. And unfortunately, the history that they were narrating about him reflects his reality.. Among them were those who were honest in what he said, and among them were those who wrote from his own point of view, highlighting the most important negatives, and there were those who wrote for a political purpose or inclination towards an idea or defending an ideology that interested him, or the victory of one person over another, and others. Deterioration of minds...but the truth that everyone does not differ from is that he was a genius and a great Persian and Muslim scholar
You can imagine that the West honored him and that he has a memorial in Bucharest, Romania, and Vienna, Austria.
This is the real difference between us and them.. We marginalize and abandon our scientific elites while they praise their achievements.
