Check out this video, MinutePhysics
I don’t know about you but sometimes I tangled up in YouTube only to snap out of it and wonder where the last two hours of my life went. I came across MinutePhysics during one of those episodes. MinutePhysics is comprised of a series of cartoon-like videos that break down some of the more complex theories of physics into explanations that are a few minutes long. Check them out here.
One of my favorites is Schrödinger’s cat.
