damn, quantum mechanics sure is some hardcore stuff. One time I couldn't find the probability of finding an electron particle within a confined space in the Hydrogen atom.
I wachted a lot of his videos and I liked him more and more! Quantummechanics is fun with him! If someone don´t understand QM, watch ALL his vidoes. Than you get it for sure!
I think it has to do with the fact that the "particle" is both particle and wave of probabilty, thats why its described by a wave function. But as soon as we try to localise the particle the wave collapses into a particle and is localised.
(don't bother about this comment)--> I think that the matter vibrates as waves in the higher dimentions, that why the wave function has a complex number in it, and when we make a measurement in the 3 dim world we "see" the physical aspect of matter.
i didnt get the story about the mouse and the cat, but maybe its because ive just watched 11 lessons in a row and my brain has given up...
is it that if the wave/particle is confined in a certain region of space, we can only say with 100% certainty that it is 'somewhere' in that region, its exact position can only be described in terms of probability?
yes. The only thing that is certain IS that is there. If you try to confine the space you will only get the probability of finding it.
The exact position cannot be calculated, since that would mean that the integral borders are one point.... so that would lead to probability of zero, of finding it at that point.
I am saying that you need a certain area in which you could calculate the probability of finding the particle (not a point).
however i am bothered by the phrase "the particle is everywhere".. wouldn't it be more appropriate if you say "the particle is somewhere within the interval being considered"?
Yup, I think what you said is a more accurate description of the particle. Later when you learnt about localizing the wave function, we do in fact confine the particle to a finite region, the classical interval you were mentioning.
I guess the main lesson is going back to the probabilistic nature of quantum mechanics. We can only say, with probabilities, where the particle is likely to be.
"something funny happens here". i love that i actually burst out laughing.

Given expeience in math up to Diff eq this lecture has been lots of fun.

i have to say, i think what he's doing is very good.
