002 Dirac Notation and the Energy Representation

[alvaro2416]

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

@alvaro2416 just added the link to the lecture description.

@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

Dirac notation is a little difficult for me...

@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.

@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
