Nathan Sidoli received his Ph.D. from the University of Toronto with a dissertation on the mathematical methods of Claudius Ptolemy. He worked for a few years as a postdoctoral fellow (UofT, NSF, JSPS), studying the transmission of Greco-Roman mathematical sciences in medieval Arabic sources, and is currently associate professor of the History and Philosophy of Science at Waseda University, Tokyo. His work focuses on foundations and methods in Greek mathematics and the transmission of Greek mathematical sciences in Arabic sources. Nathan Sidoli is Co-Editor-in-Chief of Historia Mathematica and Chief Editor of SCIAMVS.
During his fellowship at Topoi (September 2017), he works on “Episodes in the history of Greek trigonometry”. The aim is to explicate the conceptual relationship between metrical analysis and chord-table trigonometry as the fundamental locus of the theory of measuration of triangles and great-arcs on a sphere in Greek antiquity.
