From Copenhagen to pilot waves and many worlds, interpreting quantum mechanics is difficult. In this video, I try to explain them all to my wife. Let's see how I did.

00:00 Cold Open
00:16 What is Physics?
01:56 Weak Copenhagen Interpretation
04:01 Strong Copenhagen Interpretation
06:18 Determinism vs Causality
09:05 Retro Causality
12:25 Locality vs Realism
14:51 Pilot Waves
17:55 Many Worlds
22:38 Occam's Razor
25:26 What Does It All Mean?
26:43 Conclusion
