Instruct: Classify Amazon reviews into positive or negative sentiment
Query: Less babble, more physics please...

The author starts chapters by giving simple (maybe too simple) introductions. Then he starts jumping from one aspect of the subject discussed to another, feels like a bad novel in a way. Then there's the humour, and lets not forget the colorful drawings, and the pictures, and all the tables. Then, a couple of simple examples that, in no way, go in depth or cover the scope of the subject discussed. Then, BOOM! Five or six pages of problems that you're supposed to somehow solve with the little understanding you are left with after going through the nursery rhymes and eye candy.WARNING: Unless you have a great instructor, you will suffer, and I mean suffer trying to pass a physics course using this text.
