Funny QM Video

[Steve4Physics]

TL;DR Summary: Funny (but very well informed) video about QM.

Hope this is not considered off-topic, but anyone so inclined and with 4+ mins to spare might enjoy this (intentionally funny) QM video by eigenchris:

The beginning of the video is so true. In our Modern Physics course, we used Tipler and learned about the square well, Bohr's atom, and Schrödinger's equation briefly.

Then, we took Statistical Mechanics, followed by Classical Mechanics, Lagrangians, and, more importantly, Hamiltonians, in preparation for QM.

Upper-level QM was a blur with its mixin of Heisenberg matrix mechanics, and then we got to scattering angles and cross-sections. We wondered why we were learning this.

Much later, we learned, "Oh, that's how QM is used in physics to measure scattering angles and cross-sections to understand how particles interact."

I should have written a book about it. ;-)
