Episode notes
Myth of All Possible Paths
- Path integrals are a computational tool, not a literal map of reality.
- Claims that particles take all possible paths simultaneously are a misunderstanding of the math.
Wavefunction in Configuration Space
- Electron wave functions live in configuration space, not ordinary 3D space.
- Saying electrons go through both slits is a misleading simplification of quantum mechanics.
Imaginary Time Regularization
- Regularizations like imaginary time are mathematical tricks, not physical reality.
- Path integrals are a mathematical tool, not a literal description of nature.
