The Crisis In Physics

In this brief introduction to a five-part series, David Albert describes one of the most extraordinary moments in modern science: when leading physicists concluded that quantum mechanics had shattered the core aspiration of the scientific project. He traces how experiments on subatomic particles led Niels Bohr and the Copenhagen school to argue that any straightforward, realistic account of what happens behind the scenes of quantum experiments would inevitably collapse into paradox. Crucially, this wasn't an abstract philosophical critique. It came from working physicists simply trying to understand very small rocks passing through measuring devices. Albert introduces the measurement problem at the heart of quantum theory, touches on Bell's theorem, and previews three major attempts to resolve the crisis. He also recommends accessible books for viewers who want to explore the technical details further.
