Query: Technical, Sometimes Dry. Always Good

Let me preface this by saying I love physics. Especially mechanics. The book explains how techniques work and why.Some of us learn better this way. If you know why a technique works, you will probably learn to apply it better. This book can help you understand the hows and whys, if you can concentrate on the descriptions. They can be dry and technical.If you're missing something in a technique, this book may be able to help you.
