A Genius !!! The Medieval Golden Age, Al-Biruni and the Earth’s Radius البيروني و حجم الارض

Al-Biruni is considered as one of the greatest scholars of the medieval Islamic era and was well versed in mathematics, astronomy, physical and natural sciences, and also distinguished himself as a geographer, historian, chronologist and linguist. He is also considered as impartial writer on custom and creeds of various nations and was given the title al-Ustdadh (“The Master“). According to Francis Robinson, Al-Biruni earned the “founder of Indology“ and “first anthropologist“ titles for his remarkable description of early 11th-century India. NB : Because of a calculation error, it is necessary to correct, instead 884 meters, the Mountain’s height is in fact h=441 meters.
