For his novel ‘Angles et Grandeur’. Published by the Walter De Gruyter, Berlin .
Professor Roshdi Rashed was born in Cairo, Egypt, on April 5, 1936. He obtained his B.A. in Philosophy from the University of Cairo, his B.S. in Mathematics from the University of Paris. Trained in theory of numbers and algebraic geometry, he obtained his Doctorat d’Etat in History of Mathematics and its applications from the University of Paris. He is Emeritus Director of research CNRS (Centre d’histoire des sciences et des philosophies arabes et médiévales-University of Paris 7), Honorary Professor at the University of Tokyo, Emeritus Professor at the University of Mansourah (Egypt).
His first contributions in History of Mathematics and Sciences (1957-1965) were mainly concerned with the theory of probability and its applications in social sciences. He studied from one side some axiomatic systems in probability calculus, the application of probability models in social sciences, and from other side the history of some applications since the 18th century, to explain the true difficulties of application of mathematics in social sciences. These studies were distinguished by the bronze medal of the C.N.R.S. From 1965 on, his main aim was the history of mathematics in Arabic, and their application, particularly in optics. (For more details, please see: http://www.sphere.univ-paris-diderot.fr/spip.php.article171).
The study discusses the concept of angle and its relation to Archimedean and non-Archimedean theories of measurement, tracing the history of discussions from Euclid to Kamal al-Din al-Farisi. The volume presents first editions of over twenty texts, either in Arabic or Greek by the greatest mathematicians and philosophers of the time. The texts are translated into French and supplemented with extensive commentary.
