To those of us who are not mathematicians or physicists Einstein's theory of relativity often seems incomprehensible exotic & of little real-world use None of this is true Daniel F Styer's introduction to the topic not only shows us why these beliefs are mistaken but also shines a bright light on the subject so that any curious-minded person with an understanding of algebra & geometry can both grasp & apply the theory Styer starts off slowly & proceeds carefully explaining the concepts undergirding relativity in language comprehensible to nonscientists yet precise & accurate enough to satisfy the most demanding professional He demonstrates how the theory applies to various real-life situations with easy equations & simple clear diagrams Styer's classroom-tested method of conveying the core ideas of relativity-the relationship among & between time space & motion & the behavior of light-encourages questions & shows the way to finding the answers Each of the book's four parts builds on the sections that come before leading the reader by turn through an overview of foundational ideas such as frames of reference revelatory examples of time dilation & its attendant principles an example-based exploration of relativity & explanations of how & why gravity & spacetime are linked By demonstrating relativity with practical applications Styer teaches us to truly understand & appreciate its importance beauty & usefulness Featuring worked & end-of-chapter problems & illustrated nontechnical explanations of core concepts while dotted throughout with questions & answers puzzles & paradoxes Relativity for the Questioning Mind is an enjoyable-to-read complete concise introduction to one of the most important scientific theories yet discovered The appendixes provide helpful hints basic answers to the sample problems & materials to stimulate further exploration
