More technically inclined readers may find our level of detail inadequate. Calculators at the ready, they cry "Forget Review and Motivation, where are the blueprints?" (or perhaps DXF files nowadays). Our thought was that this book is already targeting a niche market, and if it consisted of a complete design for every system onboard, only our chief engineer would actually read it. Additionally, the time and energy required to explore everything in detail would greatly delay the book's completion. So our main goal is simply to make sure each potential problem can be solved and get a feel for the solution. Such readers must console themselves with the thought that a more readable book will hasten the spread of our ideas and thus the progression to a stage that involves DXF files.
