0There is also little doubt that the development of astronomy owes a great deal to the work of Muslim astronomers. As far back as the early 9th century, the Caliph Al-Ma’mum founded an astronomical observatory in Shammasiya in Baghdad and Qasiyun in Damascus. Five hundred years later, in 1420, Prince Ulugh Bey built a massive observatory in Samarqand, which was then followed in 1577 by another observatory built by Sultan Murad III in Istanbul.
The Ottomans had particularly well-organized astronomical institutions such as the post of chief-astronomer and time-keeping houses. Taqi al-Din, a 16th century Ottoman astronomer, created astronomical tables and observational instruments that helped measure the coordinates of stars and the distances between them.
Muslims have also made contributions in the field of chemistry by inventing many of the basic processes and apparatuses used by modern-day chemists. Working in the 8th and 9th centuries in Andalucía, Jabir Ibn Hayyan, the founder of modern chemistry, transformed alchemy into chemistry through distillation, or separating liquids through differences in their boiling points. In addition to developing the processes of crystallization, evaporation, and filtration, he also discovered sulphuric and nitric acid. The historian Erick John Holmyard stated that Hayyan’s work is as important, if not more, than that of Robert Boyle and Antoine Lavoisier, two European chemists who are frequently attributed to creating modern chemistry.
Indeed our very modern and globalized world today would not be able to move so quickly if it were not for the genius of Ibn Firnas, a Muslim engineer of Andalucía who in the 9th century constructed a flying machine, thus becoming the world’s first aviator. In 852 he jumped from the minaret of the Grand Mosque in Cordoba, Spain, using a loose cloak stiffened with wooden struts. Although he hoped to glide like an eagle, Ibn Firnas did not, though he is credited for creating the first parachute. -

0Bu da bilim ile alakalı bir parça. Bu böyle gidiyor. Tıp, astronomi, felsefe... Ülkemiz bize bunları öğretmediğinden, dininden utanan bir nesil olarak yetişiyorsunuz. Onların isteği de buydu zaten.
