Ali Kuşçu was a Turkish mathematician and astronomer who lived in the mid-15th century and served in the Ottoman and Timurid Empires. He was educated in Samarkand and then came to Istanbul to serve Mehmet the Conqueror. Kuşçu's work had a profound impact on the medieval Islamic world and especially on Turkish culture and science. With the innovations he brought to astronomy and the value he added to Turkish science, he made a great contribution to the "golden age" of the Ottoman Empire.

IMPORTANT ASPECTS OF THEIR WORK
Ali Kuşçu revived the Ottoman Empire's interest in astronomy by creating astronomical observations and theories. In particular, his work on trigonometry and moving celestial bodies became a reference for later generations. His interpretations and additions to the works of Ptolemy also have an important place.

ROLE IN THE OTTOMAN EMPIRE
Ali Kuşçu's invitation to Istanbul by Mehmet the Conqueror increased not only his prestige, but also that of the Ottoman scientific world. Kuşçu made important contributions to the madrasah system established after the conquest of Istanbul and trained many students there.

CULTURAL IMPACT
Ali Kuşçu's works had a great impact not only in the Ottoman Empire but also in the Timurid Empire and the Islamic world. His work in astronomy and mathematics, which reflected Turkish cultural elements, also helped to expand the scientific activities of the Ottoman Empire.

A LEGACY AMONG THE STARS
Ali Kuşçu's scientific works still provide important references for modern astronomy and mathematics. His contribution to the promotion of science in Türkiye and the Turkic world, in particular, and to providing a historical perspective cannot be overstated.
