TL;DR

Quantum physics explains the smallest parts of the universe through wave functions and phenomena like superposition and entanglement.

Transcript

quantum physics has a mystique of being complicated and hard to understand in fact Richard Fineman who won the Nobel Prize for his work on quantum electrodynamics said if you think you understand quantum physics you don't understand quantum physics which is kind of disheartening for us because if he didn't understand it what chance to the rest of u...
