British theoretical physicists Cox and Forshaw offer lay readers a fascinating account of modern scientists' view of the world, and how it got that way. Without using complicated mathematics, Cox and Forshaw show how the search for "mathematical consistency" can guide scientists in finding the "laws that describe physical reality." The authors provide the historical context that set the stage for Einstein's discovery, providing an easy-to-grasp explanation of counterintuitive experimental evidence, demonstrating how the speed of light acts as a "cosmic speed limit," the exception that proves the rule of relativity. The authors also clearly explain the tide shift that Einstein caused, transforming scientists' understanding of the world-"common-sense notions regarding space and time are dashed and replaced by something entirely new, unexpected, and elegant." Though the basics are covered in detail, there's plenty here for science buffs to ponder.

“Cox and Forshaw make a good point in stating that space, time, and even nature are contained within the equation…Although the theory might be tricky, the authors show they understand readers are not on their level. By going one step at a time, the buildup ensures each chuck is absorbed slowly rather than all at once.”
“This book takes the world’s most famous equation apart and puts it back together again in a way that is lively and understandable. We were delighted to find our knowledge of equations—long forgotten since leaving school for some of us—reinvigorated and felt ourselves rediscovering our enjoyment of mathematics.”
London Daily Telegraph, 10/19/10

“An easy survey of science for non-scientists.”

I think on the whole the attempted simplifications work well and I was a great way to approach the subjects from a more personable point of view. It does jump a little and feels like it ties itself in knots at times... but welcome to the world of physics where even concepts of simplicity can be complex to understand. It's purely a field of interest for me, and just one facet of understanding the world around us. The math is minimal, so don't panic.
It can't explain how Nicholas Cage actually made a Ghost Rider sequel - some things in the universe are even beyond the greatest minds understanding.
by Brian Cox is easily the best book I've ever read about special and general relativity targeted at the general reader. Cox takes the reader deeply into the theory. He painlessly introduces the reader to the basics of the mathematics needed to understand some of the more beautiful aspects of both theories and he does so more skillfully than any other writer on the subject - including Einstein himself. This is a must read for anyone who wants to be more scientifically literate.
If you could handle geometry in school, none of the topics will be over your head.
1. Einstein and his colleagues deduced the nature of the universe by using simple mathematic formulas. For example, the elemental Pythagorean Theorem of geometry is used to calculate the slowing down of time as objects approach light speed. The authors point out that the most complex phenomena in the universe, from subatomic particle interactions to cosmic forces of time and space, follow the elegant rules of mathematics. Nobody knows why the seemingly infinite universe should follow these wonderfully simply rules, but it does!
2. That space and time are components of an integrated whole called spacetime. I had heard the cliché that "time is the fourth dimension" but did not understand it intellectually. This book explains how space and time are integral parts of each other. All matter moves at exactly the same speed through spacetime. If the velocity of an object through space increases, its velocity through time decreases such that the combined movement through space and time is always constant.
3. The nature of "C" has been somewhat obscured by calling it the "speed of light." "C" is the maximum attainable speed of EVERYTHING through the SPATIAL DIMENSION OF SPACETIME. A photon travelling at "C" is going at maximum velocity through space and at zero velocity through time. An object at rest travels at zero velocity through space and maximum velocity through TIME. That is why times passes fastest for objects at rest and slowest for those at light speed.
4. "C" is THE constant of the universe. Everything else is malleable. Time and space and matter and energy must shrink or expand in changing circumstances, but "C" never does. If one were to approach the speed of light the distance between the stars would shrink such that one could travel to the end of the universe in one lifetime. Fifteen billion years would have passed to people standing relatively still on earth, but for the astronaut travelling near light-speed perhaps only 20 years have passed (the 20 years is allowing time to accelerate and decelerate from rest to lightspeed and back). In a relativistic universe space shrinks into nothingness when "C" is reached. This explains why nothing can exceed the speed the light. A photon travels a dimensionless universe in a timeless instant. This also explains why travel BACKWARD through time is not possible.
5. Toward the end of the book the authors give the equation that explains every subatomic particle and every force in the known universe. It's a difficult equation comprehensible only to physicists, but still, knowing that you can express the entire nature of the universe in a few lines of mathematics is mind-bending!
If a layperson wants to comprehend the nature of the universe by reading one book, this is it!
