Purcell is great, but most of the rest of the books in the Berkeley physics series are nothing special, and they are half a century out of date at this point. (Purcell is in a third edition, so it doesn't suffer from the problem of being out of date.)
The MIT series by French is likewise extremely out of date.
Hello I am myself trying to find good calculus-based physics textbooks at an introductory level (I majored long time ago in mathematics and took some physics courses at the university but it was a long time ago and never practiced since).
People seemed to recommend "Newtonian mechanics" often though (as well as his
"Vibrations and Waves"), and I was wondering what makes you say it is "extremely out of date"? Would I make myself a disservice learning from this book (which seemed maybe less steep than K&K)?
