Who Is Ali Qushji?
Ali Qushji was a prominent astronomer and mathematician who lived in the 15th century. His full name was Alaeddin Ali bin Muhammad. The nickname “Qushji” (meaning “the falconer’s son”) was given to him because his father served as the ruler’s chief falconer.
He carried out scientific work particularly in the fields of:
- Astronomy
- Mathematics
- Physics
- Linguistics
After receiving his education in Samarkand, he came to the Ottoman Empire and took on important positions in Istanbul.

Among Ali Qushji’s contributions to science, the most notable field is astronomy. He conducted studies at the Samarkand Observatory, one of the most advanced observatories of his time.
Some of his contributions to astronomy include:
- Conducting studies on celestial movements
- Calculating planetary movements
- Advancing astronomy education
- Using new observation methods
Ali Qushji’s astronomical studies also became a source for later scientists.
Studies in the Field of Mathematics
Ali Qushji’s contributions to science are not limited to astronomy alone. He also left behind important works in mathematics.
He conducted studies particularly on:
- Arithmetic calculations
- Geometry studies
- Mathematics education
- Numerical methods
His written works were used as textbooks in madrasas for many years.
Contribution to Ottoman Science
Invited to Istanbul by Mehmed the Conqueror, Ali Qushji played a significant role in the development of scientific activities in the Ottoman Empire.
In Istanbul, he:
- Taught in madrasas
- Contributed to the scientific education system
- Advanced astronomical studies
- Strengthened mathematics education
For this reason, Ali Qushji’s contributions to science are considered significant in the development of Ottoman scientific history.
