Instruct: Classify Amazon reviews into positive or negative sentiment
Query: Ever wonder why TA got a bad name?

Look no further, and just read this book...The only thing that I wish to stress here is that if you wish to believe any positive reviews on this book, either on this amazon website or anywhere else, you ought to find at least ONE SINGLE theory from this book which the reviewer(s) dare to make any claim that he/she had benefitted so far, and then try to reproduce yourself. If you cannot, you might as well just forget all about this book and be very confident that you would not MISS ANYTHING important, except hypings.
