002 Dirac Notation and the Energy Representation

In this series of physics lectures, Professor J.J. Binney explains how probabilities are obtained from quantum amplitudes, why they give rise to quantum interference, the concept of a complete set of amplitudes and how this defines a "quantum state".

anyone know where i can find the problem sets for this lectures?

@alvaro2416 just added the link to the lecture description.

@craxons it is very straightforward actually. if you are not familiar with elementary linear algebra (vector spaces, linear operators etc) then it is clear that you find it difficult. he could simply say the bra's form a vector space and ket's as well and everything is said

@S1CKDRIFT3R I've been practicing the notation... there are just two ways for using Dirac's notation: the discrete case(sum) and the continous case(integral). A quantum state, in math terms, is just the linear combination of the Hilbert space basis. It is very simple. =D

@craxons I know what you mean, people say its quite intuitive but I prefer using the path integral formulation or just shrodingers form with differentials. But if I could learn it, I'm sure you can too.

Dirac notation is a little difficult for me...

Great lecture!
