I want to thank you for consistently suggesting Arnold's Texts(s) as recommendations in various threads. I have recently stumbled across his "Mathematical Methods of Classical Mechanics" book and I'm eager to start. In the preface it says something to the extent of "this text assumes no prior knowledge of mathematics outside the usual courses taken by physics students (differential/integral calc, differential equations, and linear algebra)". I desperately need to work through this book.

Thank You vanhees71. I see your reply to my question about Dirac notation in an email from PhysicForums but I do not see it in the thread. However the email said I needed to reply in the thread. In any case thank you, I was guessing it was to stress something that had yet to be introduced in the book (i.e. the completeness relation)

Thanks vanhees71 - a 'like' from you is an honor !

Lieber Hendrik,
kannst Du hierzu was beitragen?
Ich finde keinen rechten Grund, warum sich der Impuls als p->p-mv unter Galilei-Boosts transformiert, Lz ->Lz.
