Focus on Simplicity Energy: A Textbook is written for people who want to be able to be able to discuss energy with confidence. There is nothing quite like knowing data—and knowing how to handle the numbers—so that you can hold your own in conversations, write sensible letters to the editor, and distinguish fact from fiction. It is a superb choice for the home-schooling crowd. This book is printed in full color in 8-1/211 format, Perfect bound. It deals with realism from the get-go in a completely non-partisan way. The equation for power from a hydroelectric dam is the same, regardless of any political, philosophical, religious, or sociological point of view. The distance between A and B is a simple concept, but it can easily become confusing if one person expresses the distance in leagues, another in furlongs, another in nautical miles, another in inches, another in lengths of football fields, and another in parsecs. Energy is often expressed in many disparate units, but power is worse, because it involves any one of the energy units plus any one of several time units (seconds, minutes hours, days…). Solar intensity is worse yet because it involves all of the energy units, all of the time units, and numerous units for area. Energy: A Textbook enables you to reduce such complexities to their basic simplicity, and to develop a coherent view of energy that applies just as well at the international level as at the off-the-grid farm level. Energy is inherently a quantitative subject. Numbers are not only unavoidable, but they should be embraced. With them, you hold the key to evaluating options on an equal-footing basis. Without them, there is no meaningful distinction between a grain of sand and a desert, nor between a pinwheel and a giant wind turbine. Fortunately, there are calculators and computer spreadsheets that make it a breeze to perform the calculations. Data about energy usage are readily available on the Internet. Energy: A Textbook shows how to do all the necessary steps, and has exercises throughout the text so that you can check your results. The book has very little “math”; there are a few equations here and there, but no fancy derivations, no trigonometry, no Name & address _________________________________ _________________________________ _________________________________ _________________________________ ___ Energy: a Textbook (special offer) @ $25.00 _________ Shipping (Priority Mail) @ $5.00 ______________________
simultaneous equations, or any of that stuff that some people find befuddling.
There are no diversions into side issues like politics, environmentalism, climate, or any other hot-button issues. The first step in understanding anything is to learn the facts. Let Energy: A Textbook guide you through this wonderland. List price $37.50. Your price $25.
