The Ghost of Theorist Future

The video explores how to develop a deeper conceptual understanding without relying on experiments, using a thought experiment involving a ghost from the future. It discusses the impact of the message that determinism is gone and how this could change the work of a classical physicist. The video examines the idea of conservative radicalism and the challenges of rethinking physics without determinism, ultimately introducing the principle of least action as a new way of understanding classical physics.

How can a physicist approach their current understanding of physics in a radically different way?

What does the principle of least action suggest about classical physics?
