Just wanted to say thank you for all the effort you put into your videos! They must take a fair bit of time and the explanations are so clear. Many thanks and keep up the excellent work! :)

Hi Doc. I have a question. Would an atomic nucleus with spin angular momentum cause frame dragging similar to what we measured from the Earth with Gravity Probe B? I would imagine it would but it would be random framing dragging. Say I could produce a material which exhibits nuclear ferromagnetic ordering, would it produce ordered frame dragging and function as a gravitomagnet?

The V(x,t) term has been bothering me since I learned the schrodinger equation. It's always given as an assertion which is separate from the state of any particles or wavefunctions, as if it was an independent entity in the model. But it does come from somewhere, and QM will never make sense without computing it from psi.

Spin quantum number "S" is always 1/2, it's magnetic spin q.n which is either 1/2 or -1/2..
@wdobni6 жыл бұрын
its a lovely lecture with wonderful mathematics........but is spin actually based on reality? other than the numbers and arrows, what is spin? it is said to be a quantum concept but the nucleon or electron isn't actually spinning in the classical sense........does spin have any analogy in the mundane real world of the human senses and human experience? does 'spin' exist in any real sense? or is it a result of mathematical invention?

How can an electron which is spinning in one direction, suddenly spin in the other direction without slowing down and stopping first?

@Fematika8 жыл бұрын
Quantum spinning isn't a physical process, it is more of a mechanical process. It isn't an actual spin, it is just the property of an electron that is mechanical and non-physical.
