Organiser : Agathe Keller, Karine Chemla, Christine Proust, (CNRS, CHSA, SPHERE)
This seminar is organized around a presentation of a primary source and the problems it raises, followed by a reading of this published and translated source. A session of the seminar can last up to 3 hours, and is conducted by experienced researchers, doctoral students or even master’s students.
This seminar has a declension in the form of the cuneiform text reading seminar for those interested in cuneiform writing.

A delicate method for the calculation of π in an anonymous 15th century text in Arabic
In the history of mathematics, π as a special number and an important ratio has been calculated by various mathematical methods, invented to produce a better approximation. Al-Kāshī, a Persian astronomer and mathematician of the 14-15th century, is mostly known for his calculation of π correctly to 9 sexagesimal digits. In this reading/seminar,, we will decipher and study an abridged Arabic mathematical text, which is devoted to a different method to compute π. This anonymous text from the 15th century, referring to al-Kāshī, evidently is supplementary to his work, presenting a method with two different approximations for the computation of π.
