In his usual style, Feynman teaches us not only Newtonian and Keplerian orbital mechanics, but he does it in a new and amusing manner. Most importantly, in the broader view, he reinforces one of his greates tlessons of his teaching career - there's no single "right way" to prove, demonstrate or teach something. We all (nearly all ?) learn orbital mechanics through calculus. It's not a visual nor intuitive way of doing it, and it's a hard slog. Feynman's (actually it's probably Newton's) method does it through simple plane geometry that the ancient Greeks would understand.
The authors are to be congratulated on dusting off these lecture notes and presenting them so well packaged. They're well presented, accessible, and given just the right amount of background context.
Feynman fans will like this book anyway, but it's also a good taster for Feynman's style that any child studying GCSE applied maths or mechanics could understand.
