Ottoman Empire - Science and Technology

Science and Technology

The Ottomans managed to build a very large collection of libraries. Sultan Mehmet II ordered Georgios Amirutzes, a Greek scholar from Trabzon, to translate and make available to Ottoman educational institutions the geography book of Ptolemy. One of the oldest sources on the history and philosophy of Christianity was also developed for the palace school: the İ'tikad nâme, a work on Christian beliefs by Patriarch Gennadious. Another example is mathematician Ali Qushji from Samarkand, who wrote twelve volumes on mathematics.

Ali Kuşçu (1403–1474) found empirical evidence for the Earth's rotation through his observation on comets and concluded, on the basis of empiricism rather than speculative philosophy, that the moving Earth theory is just as likely to be true as the stationary Earth theory.

Kuşçu also improved on Nasīr al-Dīn al-Tūsī's planetary model and presented an alternative planetary model for Mercury.

Taqi al-Din later built the Istanbul observatory of Taqi al-Din in 1577, where he carried out astronomical observations until 1580. He calculated the eccentricity of the Sun's orbit and the annual motion of the apogee.

In 1660 the Ottoman scholar Ibrahim Efendi al-Zigetvari Tezkireci translated Noël Duret's French astronomical work (written in 1637) into Arabic.

Şerafeddin Sabuncuoğlu was the author of the first surgical atlas and the last major medical encyclopedia from the Islamic world. Though his work was largely based on Abu al-Qasim al-Zahrawi's Al-Tasrif, Sabuncuoğlu introduced many innovations of his own. Female surgeons were also illustrated for the first time.

An example of a watch which measured time in minutes was created by an Ottoman watchmaker, Meshur Sheyh Dede, in 1702.
