I finally buckled down and finished this book. I certainly appreciated getting a review of all of all of these topics and concepts learned (or glossed over) throughout school. It was a great refresher course. However, in her effort to make is "accessible" to the masses, she ends up going over the top, being annoyingly condescending and talking down to the reader. It is not something to be read on consecutive nights of reading, but it is a great reminder of basic scientific principles that it is important to understand.
