Hi thx you both for your answers and I will take a look at the books you have recommended. thx einKI

Hi I used the last few month two make me familiar with quantum mechanics and read two books. The Feynman lectures on physics and Principles of Quantum Mechanics (R. Shanker). I think I have no problems with the bra-ket notation and solving the Schroedinger equation for some simple particle...

Well I think that summarizes it pretty well. And I am definitely willing to learn old things in a new way. The question remains how I should start. Is it a good idea to work mathworld or wikipedia or whatever from set theory , linear algebra, etc... up or is there any book which I should...

Hi Well yes and no. Yes because I have used that stuff many times and No because it wasn't even mentioned that that is called a vector space. And that's the main problem I think we did do much calculation and to less math. For example when I read about Hilbert Space there was a reference about...

Hi I am searching for some kind of mathematical "reference". My math knowledge is mainly from a five year technical school and some basic university courses. I can solve equations (linear and differential), use vectors and matrices, use geometry in 2/3 D, use probability and statistics...

Hi Thank you both for the answers. It clarified a lot for me. by einKI

Hi thx for that however I have to ask some questions about it. The Lagrangian describes how a system acts at a given action but it doesn't describe which input you have to the action. I mean in classical mechanics you can say well I have a ball with mass m and radius r and use the...

Hi Is there anywhere a list of all constants (with their values) and fundamental equations (which can not be constructed from any other equations) of the standard model? thx einKI

Hi the link is indeed very good to understand the attractive force in QED. thx you for that. by

Hi I have some problem to get insight into the mediation of the electromagnetic force and hope someone here is able to help me. If you look at the Standard Model there is the photon which acts on electrically charged particles like electrons and quarks. The electromagnetic force is...
