Works

Sevim Tekeli's works mainly focus on the history of Ottoman astronomy, particularly on the works of the famous astronomer Taqi al Din.
When Professor Tekeli started her doctoral studies, it was very hard to find any scientific study and materials in Turkey concerning the history of Ottoman science. She determined to overcome such problems. Eventually, Tekeli overcame all these challenges and completed her doctoral thesis, "The comparison of the observational instruments of Nasir al Din al Tûsî, Tycho Brahe and Taqi al Din", under the supervision of Aydın Sayılı in 1956. Her doctoral thesis in which she made comparisons between Nasir al Din al Tûsî, Tycho Brahe and Taqi al Din in terms of observational instruments they had used was later published with the same title.
She was also interested in the development of scientific endeavour in the 17th century Western Europe and also, in comparing the developments in Russia at the time and in the Ottoman Empire in terms of scientific activities and achievements. She also examined the effects of the Ottoman Empire on Renaissance. She particularly analyzed the reasons behind the superiority and leadership of the Ottoman Empire in the Islamic World at the beginning of the 17th century.
She continued her research on Taqi al Din and published another book, The Brightest Stars of Construction of the Mechanical Clocks that was based on her professorial thesis. In this book, she revealed that Taqi al Din was one of the most important astronomers of the 16th century. She has also studies concerning the map of Piri Reis and Muhyi al Din. She was one of the earliest Turkish scholars uncovering the astronomy activities during the period of Ottomans.
