It's a blog! Mainly of book reviews.
I'm parking this one because it doesn't cover what I need. I'm not rating it because it might be good or bad and I haven't read enough of it to judge. The fact that it assumes what I wanted to learn just means it isn't the book I need.
The first chapter presents a very austere but elegant exposition of the basic principles of Newtonian mechanics. It would probably not suit beginners but this isn't a book for beginners anyway. That's about all I can say.
