Taqi al-Din Muhammad ibn Ma'ruf al-Shami al-Asadi (1526-1585) was an Ottoman Turkish Muslim polymath. He was the author of more than 90 books on a wide variety of subjects, including astronomy, clocks, engineering, mathematics, mechanics, optics and natural philosophy. Taqi al-Din's method of finding coordinates of stars was reportedly more precise from his contemporary Tycho Brahe and Nicolas Copernicus. Brahe is thought to be aware of Taqi al-Din's work.
