At the moment I'm studying for quantum mechanics the symmetries and so on. there we speak a lot about Lie Algebras and groups. My question is do you know any easy way to explain these groups or a book which does it? I mean, I already read some books I found in our bibliotheque and they were quite difficult, but if I looked at them for a quite I while I understood the different passages, but never got the whole picture of it, could never see it as whole.

Thanks to anyone who can help
