Hello all, I'm currently taking an upper undergraduate two part Mechanics course using the above mentioned book by its author. He's a great professor and I was wondering if anyone else has checked out this book? It's very math heavy and I'm struggling with some of the language since I haven't been exposed much to group theory, differential geometry... The book is pretty turse, but that is probably a strength to those stronger in math. Let me know any thoughts. I could ask the author if I could post the first chapter here if people would like. :D I think the more advanced people would love this book.
