History and Philosophy of Contemporary Theoretical Physics

The scientific understanding of the physical world and the methods of physics have both undergone dramatic changes during the 20th century. The aim of this working group is to foster a network of scholars working on the history and philosophy of modern physics and to discuss both historical papers and recent/ongoing works of its members. The group focuses on the mathematization of fundamental theoretical physics, its historical development and philosophical implications. The scope of the group therefore includes primary resources associated with the development of general relativity, quantum theory and quantum field theories, together with alternative theories (such as modified theories of gravity) and rejected theories (such as unified field theory). The starting point for the group is the historical development of gauge theories, together with related concepts and theoretical practices (e.g. spinors, dimensional reduction). Just a few examples of issues that fall within the scope of the working group are the historical development of quantum gravity, varieties of realism vs. anti-realism in the context of fundamental physics, the roles of principles in theorizing, and the limits of mathematical reasoning.

Group Conveners

  • GuyHetzroni's picture

    Guy Hetzroni

    Guy Hetzroni is a member of the Department of Natural Sciences at the Open University of Israel and of the university’s Astrophysics Research Center (ARCO). He received his Ph.D. from the Program in the History and Philosophy of Science at the Hebrew University of Jerusalem in 2019, and conducted postdoctoral research as a Rothschild Fellow, visiting research fellow at the Freudenthal Institute at Utrecht University and an associate member of the Faculty of Philosophy at the University of Oxford. His research is in the philosophy of physics, focusing on epistemological and ontological questions in the context of the methods of modern physics. His current main research project conerns symmetry arguments in the context of quantum physics and gravitational theories. 


  • blessel's picture

    Bernadette Lessel

    Bernadette Lessel is a postdoctoral researcher at the Max Planck Institute for the History of Science, interested in historical epistemology of final theories, most specifically in an historical understanding of the development of fundamental physical theories into highly abstract, non-empirical formalisms. Her current research project analyses Wolfgang Pauli's engagement with unified field theory and how it influenced the early development of quantum gravity. Prior to being a postdoc in the history of science, Bernadette received a Ph.D. in mathematics from the Georg-August-Universtiät Göttingen and studied physics and mathematics at the Philpps-Universität Marburg. Bernadette also held a visiting research fellowship at the Perimeter Institute in Waterloo, CA, and a teaching fellowship at the Cohn Institute for the History and Philosophy of Science and Ideas (University of Tel Aviv).



  • NoahStemeroff's picture

    Noah Stemeroff

    Noah Stemeroff is an Alexander von Humboldt Postdoctoral Fellow at the University of Bonn and the Max Planck Institute for the History of Science. He received his Ph.D. in the History and Philosophy of Science and Technology from the University of Toronto in 2019. His research sits at the intersection of the history and philosophy of mathematics and science, and the history of philosophy. As a Humboldt fellow, he has been engaged in a study of the "mathematization of nature" implicit in the work of Hermann Weyl and Wolfgang Pauli, and their relation to the broader empiricist, idealist, and neo-Kantian traditions in twentieth century philosophy of science. This study will form part of a broader investigation into the manner in which mathematics and physics have been interwoven in the development of the gauge theories of modern theoretical physics.
