How better to learn the Special Theory of Relativity and the General Theory of Relativity than directly from their creator, Albert Einstein himself? In Relativity: The Special and the General Theory, Einstein describes the theories that made him famous, illuminating his case with numerous examples and a smattering of math (nothing more complex than high-school algebra). Einstein's book is not casual reading, but for those who appreciate his work without diving into the arcana of theoretical physics, Relativity will prove a stimulating read. --This text refers to an alternate Paperback edition.
From Scientific American
"The present book is intended," Einstein wrote in 1916, "as far as possible, to give an exact insight into the theory of Relativity to those readers who, from a general scientific and philosophical point of view, are interested in the theory, but who are not conversant with the mathematical apparatus of theoretical physics.... In the interest of clearness, it appeared to me inevitable that I should repeat myself frequently, without paying the slightest attention to the elegance of the presentation. I adhered scrupulously to the precept of that brilliant theoretical physicist L. Boltzmann, according to whom matters of elegance ought to be left to the tailor and to the cobbler." But it is elegant, in part because of the 1920 translation, by Robert W. Lawson, a British physicist who had polished his German while a prisoner of war in Austria. The introduction, by science writer Nigel Calder, guides the reader through the work section by section, even giving advice on which sections to skip, or at least not to worry about, if you can't "accompany Einstein through the forest of tricky ideas contained in this slim volume." Okay, this book isn't easy--again, in the master's elegant words, it "lays no small claims on the patience and on the power of abstraction of the reader"--but it is well worth the try.

Selected by Choice magazine as an "Outstanding Academic Title" for 2014
“This is a very high-quality presentation. The writing is lucid, and the theoretical discussions are easy to follow for anyone comfortable with the mathematics. … the work is a valuable addition to college libraries. Professionals and researchers will also want it on their bookshelves; it provides an excellent refresher on a wide range of topics and can serve as a good starting point for expanding knowledge of new or unfamiliar subjects. Summing Up: Highly recommended. Lower-division undergraduates and above.” (A. Spero, Choice, Vol. 51 (9), May, 2014)
“It describes all the major developments and theories regarding the description of the universe we live on, from the very small to the very large. … I highly recommend this book to any physicist. It will not only be a fun and an easy read but also a useful revision of all the main concepts in physics. Undergraduate and graduate physics students definitely should read it. … appropriate for scientists in other fields who have a genuine interest for physics.” (Monica Pierri-Galvao, Contemporary Physics, April, 2014)
From the Back Cover
"Basic Concepts in Physics: From the Cosmos to Quarks" is the outcome of the authors' long and varied teaching experience in different countries and for different audiences, and gives an accessible and eminently readable introduction to all the main ideas of modern physics. The book’s fresh approach, using a novel combination of historical and conceptual viewpoints, makes it ideal complementary reading to more standard textbooks. The first five chapters are devoted to classical physics, from planetary motion to special relativity, always keeping in mind its relevance to questions of contemporary interest. The next six chapters deal mainly with newer developments in physics, from quantum theory and general relativity to grand unified theories, and the book concludes by discussing the role of physics in living systems. A basic grounding in mathematics is required of the reader, but technicalities are avoided as far as possible; thus complex calculations are omitted so long as the essential ideas remain clear. The book is addressed to undergraduate and graduate students in physics and will also be appreciated by many professional physicists. It will likewise be of interest to students, researchers and teachers of other natural sciences, as well as to engineers, high-school teachers and the curious general reader, who will come to understand what physics is about and how it describes the different phenomena of Nature. Not only will readers of this book learn much about physics, they will also learn to love it.

This book reprints the six easiest chapters from Feynman's celebrated Lectures on Physics (LJ 12/15/63), which the Nobel Prize-winning scientist delivered from 1961 to 1963 at the California Institute of Technology. Intended for as wide an audience as possible, these chapters are primarily qualitative in nature, with a minimum of formal mathematics. They discuss atoms, basic physics, the relation of physics to other sciences, the conservation of energy, gravitation, and quantum behavior. While this informative work provides a relevant historical perspective on the essentials of physics, the result is somewhat superficial. Nonetheless, because Lectures on Physics is out of print and because the information is still relevant, reprinting these specific chapters was probably a realistic move. The material will be readily understood by scholars, physics students, and informed lay readers. Recommended for academic and public libraries. (Audio tape and CD packages are also available.)-Donald G. Frank, Harvard Univ. Lib., Cambridge, Mass.
