I'm currently into studying Biochemistry and Physics. I bought this book after seeing a pdf version that was part of a "Great Science Textbooks..." collection. As I started browsing the file I found myself being captivated by just about any section I skipped into. That is, I was learning and re-learning some of the fundamentals which I thought I already knew (and probably should've, but didn't), and it was like an "AHAH!" experience when the light would go on. This was great fun! I enjoyed that so much I immediately ordered the book. I began referring back to it to help me with my Biochem studies (via Lehninger and a couple other texts). The last chapter of this textbook is on Biochemistry and actually does a better job at introducing many of the key aspects of that subject than my Biochemistry textbooks. I still find myself frequently consulting this textbook and its resources for a large variety of issues that would otherwise remain subtle points of confusion or mystery.
OK I really struggle with Chemistry, and all other books demolish my interest usually with the first few sentences, THIS BOOK, HOWEVER, I'm tempted to buy it completely because it cracks me up. The author(s) are extremely sarcastic at times and tell vivid stories that have left me howling with laughter and holding my stomach. It's definitely made it easier to read, and more enjoyable. Thus far, my favorite note of sarcasm is how they feel about calculators, and my favorite story is the Nitric Acid one by the scientist in 1901.
This is a wonderful book, and I'm halfway through it. We used it for my Chem 1 and Chem 2 class, and being able to find the book at an affordable price with fast and cheap shipping was a godsend for someone who doesn't get financial aid. There are tips on how to remember things throughout the book, as well as practice problems, and comprehension testers to see if you recall important information throughout the chapter. I may or may not be biased, as a chem major, so keep that in mind, and think what you will, but I found most of the book to be an easy read and wonderful at explaining things I never understood before.
