Contributing in Science, medicine, mathematics and other inventions is far better than feeling proud of conquerors who put universities and libraries on fire. In Asia only Chinese, Iranians and Indians have given such traditions of inventions and discoveries.
All those went down the drain with british rule. Other than indians inventing the word 0 i dont know anything else they did.
Piri Reis (full name Hacı Ahmed Muhiddin Piri - Hadji Ahmed Muhiddin Piri, Ahmet ibn-i el-Haç Mehmet El Karamani; Reis was a Turkish military rank akin to that of captain) was an Ottoman admiral, geographer and cartographer born between 1465 and 1470, and died in 1554 or 1555.
He is primarily known today for his maps and charts collected in his Kitab-ı Bahriye (Book of Navigation), a book that contains detailed information on navigation, as well as very accurate charts (for its time) describing the important ports and cities of the Mediterranean Sea. He gained fame as a cartographer when a small part of his first world map (prepared in 1513) was discovered in 1929 at the Topkapı Palace in Istanbul. His world map is the oldest known Turkish atlas showing the New World, and one of the oldest maps of America still in existence anywhere (the oldest known map of America that is still in existence is the map drawn by Juan de la Cosa in 1500). Piri Reis' map is centered on the Sahara at the latitude of the Tropic of Cancer.[1]

Hezârfen Ahmed Çelebi was a legendary Ottoman aviator of 17th-century Istanbul, purported in the writings of Evliya Çelebi to have achieved sustained unpowered flight.
The 17th century writings of Evliyâ Çelebi relate this story of Hezârfen Ahmed Çelebi, circa 1630-1632:
"First he practiced by flying over the pulpit of Okmeydani eight or nine times with eagle wings, using the force of the wind. Then, as Sultan Murad Khan (Murad IV) was watching from the Sinan Pasha mansion at Sarayburnu, he flew from the very top of the Galata Tower and landed in the Doğancılar square in Üsküdar, with the help of the south-west wind.
