I read this book as part of my setwork for my AAUS Scientific Diving course.
Firstly, this is an in-depth review of diving as a whole. If you're looking for a light read this is not it. If, however, you crave more substance, this is a great place to start. I learned so much more about diving physics and diving equipment. In fact, I read it at the same time as I did my TDI Decompression Procedures book, and Advanced Nitrox, and found the subject matter in those 10x easier to grasp. That said, this book goes into a whole lot more depth than most scuba manuals -- obviously a must for scientific divers.
This brings me to my second point, which is the primary reason I've given the book 3 stars and not 4: it is very wordy and a lot of the mathematics/science problems are poorly explained. Furthermore, not enough examples and practice problems are provided. Given that this book is used for a graduate level college course I'd expect a bit more. I have to say it took me a lot longer than was necessary to understand some of the physics, which, my TDI book and instructor made very simple.
Overall, however, I learned a lot. I'd recommend this book to most people with the caveat that it is slow going and unnecessarily wordy. I'd also suggest having a good old physiology/human anatomy book by your side to help you picture more of what is happening in the human body. Pity there weren't better pictures for the initial physiology section.
