In order to preserve the memory of the late Prof. Dr. Fuat Sezgin (d. 2018) and to ensure that his significant scientific legacy serves as a source of inspiration for future generations, the 1st International Prof. Dr. Fuat Sezgin Symposioum on the History of Science in Islam, in collaboration with Istanbul University, Fatih Sultan Mehmet Foundation University, and the Prof. Dr. Fuat Sezgin Research Foundation for the History of Science in Islam held its inaugural conference between June 13-15, 2019. Subsequently, IU Press published 38 of the papers that had been presented at the conference. Following this, the decision was made to organize the symposium every two years, and preparations were undertaken for the 2nd International Prof. Dr. Fuat Sezgin Symposium on the History of Science in Islam, which was held on October 7-9, 2021 with the theme of “Methodological Approaches to the History of Science in Islam.”
The study of the intellectual output from the Islamic world as an object of research has a nearly 200-year history. Despite the efforts of many international scholars to discover, understand, and interpret the history of Islamic sciences and determine its relevance for contemporary society, many aspects of the history of Islamic sciences still exist that remain to be clarified, such as the individuals, works, theories, networks of relations, contexts, and influences. Two key questions facing researchers in this field is how to approach the history of Islamic sciences using methodological tools and how to utilize perspectives from different disciplines.
The 2nd International Prof. Dr. Fuat Sezgin Symposium on the History of Science in Islam aimed to address these issues by discussing the methodological aspects of how to research the history of Islamic sciences with a focus on the following questions:
• How does the study of the history of Islamic sciences relate to the established historiography and research methods? 
• How can the history of Islamic sciences be periodized? Is creating a periodization that encompasses all sciences possible, or should separate periodizations be established for each individual science? 
• Can special methods be mentioned for studying the period following the 13th century that is commonly referred to as the post-classical period? 
• Has the paradigm of decline in understanding the history of Islamic sciences truly expired? 
• What opportunities and weaknesses do content-oriented and context-oriented approaches have in regard to analyzing scientific texts? 
• How should the relationship Islamic sciences have with the scientific accumulation of other civilization basins be handled?
• What kind of balance should be established between continuity and originality when writing the history of scientific theories? 
• To what extent is the perspective presented by global history studies functional in understanding the history of Islamic sciences? 
• What kinds of methods and approaches should be used in teaching the history of general science at different levels, including the history of Islamic sciences?
A total of 68 scholars, 41 from Turkey and 27 from other countries such as Germany, the United States of America, Belgium, France, the Netherlands, Iran, Spain, Switzerland, Egypt, Uzbekistan, Syria, Tunisia, and Greece participated in 16 parallel sessions. The symposium was conducted in a hybrid format to take into account the ongoing pandemic, with 51 of the presenters having attended the symposium in person and 17 having presented their papers online. The symposium was also broadcast live on the internet ((https://www.youtube.com/watch?v=Q11sAL3l5CI&t=8s and https://www. youtube. com/watch?v=jyrnK3q4Loc). This collection of papers offers readers 30 of the papers that were presented at the symposium and has been organized into five main sections: Methodological Approaches to the History of Science in Islam; Mathematical Sciences; Medicine; Natural Sciences; and Geography, Cartography, and Linguistics. The hope with this proceedings book is that a small contribution can be made to preserving and passing on the scientific legacy of the late Prof. Dr. Fuat Sezgin to future generations. The organizers of the symposium would like to express their gratitude to the Ministry of Culture and Tourism and the Fatih and Üsküdar municipalities for their ongoing support, as well as the support of Dr. Ursula Sezgin, the respected wife of Prof. Dr. Fuat Sezgin, and their daughter Hilal Sezgin. Additionally, the organizers would like to acknowledge the valuable contributions from the scholars in the Symposium Honor, Science, and Organizing Committees, as well as the symposium secretariat for their hard work and dedication.

<p>When Fuat Sezgin came to Istanbul in 1943, he became a student of mathematics and engineering, only changing to Oriental Studies after meeting Hellmut Ritter. We will analyze a paper which Fuat Sezgin published in 1986 and which is a witness of his mathematical abilities. The paper includes an edition of a mathematically difficult text by Ibn al-Haytham which Sezgin reconstructed from a unique Arabic manuscript written with very few diacritical marks. In this treatise, Ibn al-Haytham discusses the theoretical and practical aspects of an instrument which he produced for determining the meridian with utmost accuracy.</p>
