Quantum physics underwent a significant transformation in the 1950s. Initially, it was formulated with complex and hard-to-interpret mathematics. Richard Feynman, however, introduced a more intuitive approach known as the path integral formalism.
Feynman's idea is that to understand quantum physics, one must consider all possible paths that a particle can take and sum over these histories.
This approach leads to a new interpretation of quantum realities called the consistent histories interpretation, which helps resolve many seemingly paradoxical situations. In this episode, we'll explore how the path integral formalism works, how it helps us understand our quantum mechanical world, and what its philosophical implications are.
