Some Things I Have Learned From Detlef Dürr -- Detlef Dürr’s Path from Mechanics of the Brownian Motion to the Mechanics of the Quantum World -- Detlef the Adventurer -- Why Bohm and Only Bohm? -- The Prodigy That Time Forgot: The Incredible and Untold Story of John von Newton -- Bohmian Collapse -- Generic Contextuality.

This volume commemorates the scientific contributions of Detlef Dürr (1951–2021) to foundational questions of physics. It presents new contributions from his former students, collaborators, and colleagues about their current research on topics inspired or influenced by Dürr. These topics are drawn from physics, mathematics, and philosophy of nature, and concern interpretations of quantum theory, new developments of Bohmian mechanics, the role of typicality, quantum physics in relativistic space-time, classical and quantum electrodynamics, and statistical mechanics. The volume thus also gives a snapshot of present research in the foundations of physics.
