Taqi ad-Din Muhammad ibn Ma'ruf

Taqi ad-Din Muhammad ibn Ma'ruf, born on June fourteenth, fifteen twenty-six, was a distinguished Ottoman polymath whose contributions spanned various fields including mathematics, astronomy, engineering, and pharmacy. Active in both Cairo and Istanbul, he authored over ninety works that explored a wide array of subjects, showcasing his remarkable intellect and versatility.

In fifteen seventy-four, the Ottoman Sultan Murad III recognized Taqi ad-Din's talents and commissioned him to construct an observatory in Istanbul. This facility became a hub for astronomical research, where Taqi ad-Din crafted sophisticated instruments such as an armillary sphere and mechanical clocks. His observations included the Great Comet of fifteen seventy-seven, utilizing European celestial and terrestrial globes that were gifted to the Ottoman court.

One of his most significant contributions was the monumental work titled "The tree of ultimate knowledge [in the end of time or the world] in the Kingdom of the Revolving Spheres: The astronomical tables of the King of Kings [Murad III]." This comprehensive text, prepared from observations made in both Egypt and Istanbul, aimed to refine and enhance Ulugh Beg's fifteenth-century Zij-i Sultani. The initial forty pages focused on calculations, followed by in-depth discussions on astronomical clocks, heavenly circles, and the three eclipses he meticulously observed.

As a polymath, Taqi ad-Din's writings encompassed not only astronomy and mathematics but also mechanics and theology. His methods for determining star coordinates were so precise that they surpassed those of his contemporaries, including Tycho Brahe and Nicolas Copernicus, who was likely aware of Taqi ad-Din's groundbreaking work.

In addition to his astronomical pursuits, Taqi ad-Din made notable advancements in engineering, including the description of a steam turbine designed to rotate a spit as early as fifteen fifty-one. His explorations in optics led to significant findings, such as the determination of light emission from objects and the observational proof of the Law of Reflection, alongside investigations into refraction.
