Quantum Mechanics is Obvious – the Movie Part 4

In this video we get our first glimpse of the Heisenberg uncertainty principal. This arises when you get two or more observables that share the same vector space but don’t share the same eigenvectors. So a definite state for one is a mixed state for the other, making the other’s value uncertain.

In my humble opinion, this fact, born out by numerous experiments, that a system can exist in a superposition of states, together with the Plank-Einstein hypothesis: E = hf, are the cornerstones of quantum theory. All the maths that I’m going through are really just our way of modelling this. Those who understand the physics better, which is probably just about every physicist on the planet, are free to explain to me why I’m wrong.

  1. Watched this a few days ago. Thanks again, Rev Dr Peter. A very interesting take on Heisenberg. I do think that you should see whether you can interest any of the online maths or physics sites in your approach. I don’t know how to go about doing this; I guess all you can do is write in (as they used to say).

    Looking forward to the next episode!

    1. Thanks StephenJP. I know Physics Forums won’t let me link to these. They, quite sensibly, try to keep out the vast mess of internet tripe that’s out there.

      I’ve run it past a couple of Physics profs, one at Oxford and one at Stanford, and they both say the basic approach is correct.

      Ideally, I’d like to find some lecturers that are about to teach a first course in QM this autumn and get them to direct their students to these. I might just email a few and see what happens.

      1. Well, there’s going to be an awful lot of stuff online next academic year, so it could be a good opportunity to break into the bubble!
