Instruct: Classify Amazon reviews into positive or negative sentiment
Query: This is what evil must look like!

All the horrible things written in the other reviews are true. There are tons of typos. The derivation of the formulas is short. Worst of all, the explanation of the concepts is extremely confusing. I gave up using the book after i finished chapter 6 (entropy).I just found out of the library of my university had "Fundamentals of engineering thermodynamics" by Michael Moran. The rating of it is pretty good on Amazon. I am gonna go borrow the book tomorrow and check it out. I hope this book is much better.
