Understanding Quantum Mechanics

The video explores quantum mechanics, focusing on the peculiar behavior of electrons in experiments. It discusses how traditional questions about electron paths become nonsensical, likening them to category mistakes. The concept of superposition is introduced, where electrons appear to be in multiple states simultaneously. Despite reliable equations predicting these phenomena, contradictions arise when observations show electrons in definite positions. This leads to the measurement problem, highlighting the need to reconcile quantum theory with empirical observations.

What does quantum mechanics suggest about the location of electrons?
