- The requirement that particles be indistinguishable in quantum mechanics does have observable effects, producing an effective "exchange force" whenever two single-particle wavefunctions overlap. (This lecture is part of a series for a course based on Griffiths' Introduction to Quantum Mechanics. The Full playlist is at th-cam.com/users/playlist?list=...)
Fundamentally understanding what bonding/antibonding orbitals are was one of the core reasons why I began my journey into quantum physics. This lecture was a moment in my quest to know the universe that I'd been working for almost a year to arrive at. It may seem silly, but this is one of the most important milestones in education I have reached. Thank you for using that example. I cannot express in words the excitement it brought me. My heart is racing and I'm being flooded with serotonin right now! LFG!! MORE PHYSICS!! YES!!!
your videos are great!!
Thanks for the hard work producing them!
you're the best!
This has helped a lot!
What if we add a third particle and try to swap them around? It can't possibly be that all 3 are the opposite phase as one another?
32:50 "Because electrons are fermions" -- I was under the impression fermion == spin 1/2, but that statement was made in a context without spin?
I think categorizing indistinguishable particles with antisymmetric wavefuntion would a more generalized definition of fermions
Correct me if I am wrong, I am still trying to figure these things out
QM made easier thank you
