Query: For the love of physics ...

Here's the deal. If ya wanna do this whole physics thing vanilla-style, go buy and read a nice physics textbook. If you want to taste physics - really take it in, like a delicious chocolate mousse or a symphony orchestra or Shakespeare done by British folk, this is where you have to be. If you have the resources, the best way to really dive in is to listen to the actual lectures and use these great sets of books as a resource as you go along - and then to take it all in again afterwards (and the books clean up the mistakes here and there in the lectures).I am not a scientist nor an engineer, I just like to learn stuff from the best and this is the best. When my wife asks me why I am laughing to a man in the 1960's lecturing about "the characteristics of forces" (Volume 1, Chapt. 12), it is truly an inside joke that cannot be explained, but instead must be experienced.Textbook vs. Laurence Olivier, ... the choice was simple for me, and I will never be the same.
