The Swiss Physical Society started its IYQ2025 activities in 2024 with the historical symposium about Louis de Broglie – 100 years of wave-particle dualism, held as a vernissage at its annual meeting in Zürich, and continues the tradition at the joint annual meeting with the colleagues of the Austrian Physical Society (ÖPG) in Vienna in August 2025. One of the foci will be the scientific work of Wolfgang Pauli and Erwin Schrödinger in the years around 1925. Both physicists were born in Austria, but spent parts of their careers as professors of Physics in Zurich.
The eminent speakers with their presentations are :

• Christoph Lehner, Max-Planck-Institut für Wissenschaftsgeschichte Berlin: The Tangled Tale of Entanglement: New Discoveries from Schrödinger’s Research Notes

• David Kaiser, Department of Physics, MIT: Scenes from the Quantum Century: From Curious Hippies to Novel Tests of Bell’s Inequality

• Alyssa Ney, LMU München: Philosophy of Quantum Mechanics Beyond the Measurement Problem

• Beatrix Hiesmayr, Universität Wien: Wolfgang Pauli’s and Erwin Schrödinger’s Insights from the Perspective of a Modern Quantum Technologist

This symposium will take place on 18 August 2025 in the afternoon, and is free of charge.
