The Bohr-Einstein debates

The Bohr-Einstein debates centered on whether quantum mechanics provides a complete description of reality. Einstein believed that particles have predetermined properties and that randomness was just a limitation of knowledge, advocating for a complete, deterministic theory. Bohr argued that quantum mechanics intrinsically involves probabilities and that particles don't have definite properties until measured. Their debate highlighted core philosophical differences about reality, certainty, and the nature of scientific theory. Experiments over time, such as Bell’s theorem tests, support quantum mechanics’ view that entangled particles exhibit correlations impossible to explain by local hidden variables, favoring Bohr’s interpretation.
