Lecture 1 | Modern Physics: Quantum Mechanics (Stanford)

I imagine the reason no one is under 40 would be the cost and the fact that most young people are skint, not to mention understanding the subject O_o everything is yet isn't unless your not looking, then its different again! I wish I understood why that is the case (slit experiment, im not crazy)

what is skint?

english slang, broke, out of cash, no dollar, zero pennys zero pounds, nada currency, skint.

We need courses in field theory and strings. If anybody can explain these it would be Susskind.
How about it Stanford?

Wow... I know what he's talking about and he's still confusing me. I can't imagine being a 70 year old retiree with a limited physics background sitting there listening to this guy,

If I may respond, MIT uploads amazing videos as well.

Good for you.

Non commutative algebra

Take electron - symbol (e)
Take proton - symbol (p)
They are absolute different particles.
And interaction between electron and proton
is not the same than interaction between
proton and electron :
ep ≠ pe ( Uncertainty principle.)

Another example:
A thing called shoe and a thing called sock along with
the operator and which combines shoe and sock things.
If you play around with it, you will find
that the order is fairly important.

I think you need to go look up what an electron is and a proton is. you'll find that your first statement is wrong. I also advise you go look up the definition of interaction.
