Dr. Verkhonshansky and Dr. Siff have written an absolute masterpiece, but this one’s not for the layperson at all. If you are a science nerd, as I am, you will love the deep dive and complexity of the massive information presented...
The most comprehensive book to date was written by Robert Tisserand and Rodney Young. This book however is not for the layperson (5.2 pounds of small type and very sciencey — full of chemistry and research).
