Relativity and Common Sense


Book Description

This radically reoriented and popular presentation of Einstein's Special Theory of Relativity derives its concepts from Newtonian ideas rather than by opposing them. It demonstrates that time is relative rather than absolute, that high speeds affect the nature of time, and that acceleration affects speed, time, and mass. Very little mathematics is required, and 60 illustrations augment the text.

What Is Relativity?


Book Description

A renowned astrophysicist’s approachable introduction to Albert Einstein’s theory of relativity and its application in our daily lives. It is commonly assumed that if the Sun suddenly turned into a black hole, it would suck Earth and the rest of the planets into oblivion. Yet, as prominent author and astrophysicist Jeffrey Bennett points out, black holes don't suck. With that simple idea in mind, Bennett begins an entertaining introduction to Einstein's theories of relativity, describing the amazing phenomena readers would actually experience if they took a trip to a black hole. The theory of relativity reveals the speed of light as the cosmic speed limit, the mind-bending ideas of time dilation and curvature of spacetime, and what may be the most famous equation in history: E = mc2. Indeed, the theory of relativity shapes much of our modern understanding of the universe. It is not “just a theory”―every major prediction of relativity has been tested to exquisite precision, and its practical applications include the Global Positioning System (GPS). Amply illustrated and written in clear, accessible prose, Bennett's book proves anyone can grasp the basics of Einstein's ideas. His intuitive, nonmathematical approach gives a wide audience its first real taste of how relativity works and why it is so important to science and the way we view ourselves as human beings. “Well-written and uniquely readable . . . Bennett carefully avoids bombastic statements and “spectacularization” of the subject.” —Alberto Nicolis, Columbia University “I have read lots of introductions to relativity, but none is as clear and compelling as this one.” —Seth Shostak, Senior Astronomer, SETI Institute




Physical Reality and Common Sense


Book Description

The conventional interpretation of modern physics is difficult to comprehend because it is not consistent with our sense based paradigm for physical reality (i.e., common sense). For example, the conventional interpretation of special relativity assumes time travel to the past is possible, while it is obviously not possible according to our common sense paradigm. In Physical Reality and Common Sense, John Bell's preferred frame interpretation of special relativity and quantum mechanics, supported by the now known structure of the universe, is used to construct an entirely new description of physical reality that will change the very foundations of modern physics.




The Keepers: The Box and the Dragonfly


Book Description

Experience the fantastic adventure filled with magical objects, secret sects, and life as we know it on the line! Mixing magic and physics, Ted Sanders has created an epic story that has the feel of classic fantasy but twists it into something new and innovative. From the moment Horace F. Andrews sees the sign from the bus—a sign with his own name on it—everything changes. The sighting leads him underground, to the House of Answers, a hidden warehouse full of mysterious objects. But there, he finds only questions. What is this curious place? Who are the strange, secretive people who entrust him with a rare and immensely powerful gift? And what is he to do with it? When Horace finds the Box of Promises in the curio shop, he quickly discovers that ordinary-looking objects can hold extraordinary power. From the enormous, sinister man shadowing him to the gradual mastery of his newfound abilities to his encounters with Chloe—a girl who has an astonishing talent of her own—Horace follows a path that puts the pair in the middle of a centuries-old conflict between two warring factions in which every decision they make could have disastrous consequences.




You are (not) Small


Book Description

Not being able to agree who is small and who is big, two fuzzy animals have their argument settled by a couple of mystery guests.




Very Special Relativity


Book Description

Einstein's Special Theory of Relativity, first published in 1905, radically changed our understanding of the world. Familiar notions of space and time and energy were turned on their head, and our struggle with Einstein's counterintuitive explanation of these concepts was under way. The task is no easier today than it was a hundred years ago, but in this book Sander Bais has found an original and uniquely effective way to convey the fundamental ideas of Einstein's Special Theory. Bais's previous book, The Equations, was widely read and roundly praised for its clear and commonsense explanation of the math in physics. Very Special Relativity brings the same accessible approach to Einstein's theory. Using a series of easy-to-follow diagrams and employing only elementary high school geometry, Bais conducts readers through the quirks and quandaries of such fundamental concepts as simultaneity, causality, and time dilation. The diagrams also illustrate the difference between the Newtonian view, in which time was universal, and the Einsteinian, in which the speed of light is universal. Following Bais's straightforward sequence of simple, commonsense arguments, readers can tinker with the theory and its great paradoxes and, finally, arrive at a truly deep understanding of Einstein's interpretation of space and time. An intellectual journey into the heart of the Special Theory, the book offers an intimate look at the terms and ideas that define our reality.




Relativity and Geometry


Book Description

Early in this century, it was shown that the new non-Newtonian physics -- known as Einstein's Special Theory of Relativity -- rested on a new, non-Euclidean geometry, which incorporated time and space into a unified "chronogeometric" structure. This high-level study elucidates the motivation and significance of the changes in physical geometry brought about by Einstein, in both the first and the second phase of Relativity. After a discussion of Newtonian principles and 19th-century views on electrodynamics and the aether, the author offers illuminating expositions of Einstein's electrodynamics of moving bodies, Minkowski spacetime, Einstein's quest for a theory of gravity, gravitational geometry, the concept of simultaneity, time and causality and other topics. An important Appendix -- designed to define spacetime curvature -- considers differentiable manifolds, fiber bundles, linear connections and useful formulae. Relativity continues to be a major focus of interest for physicists, mathematicians and philosophers of science. This highly regarded work offers them a rich, "historico-critical" exposition -- emphasizing geometrical ideas -- of the elements of the Special and General Theory of Relativity.




Understanding Einstein's Theories of Relativity


Book Description

Clear, concise exposition of both the special and general theories of relativity, intended for nonscientific readers with a knowledge of high school math. Topics include simultaneity, time dilation, length contraction, the possibility of travel to a distant star, non-Euclidean geometries, black holes, and the structure of the universe. 158 illustrations.




Reclaiming Common Sense


Book Description

Common sense is the foundation of thinking and of human action. It is the indispensable basis for making our way in the world as individuals and in community with others, and the starting point for finding truth and building scientific knowledge. The philosophy of common-sense realism deeply informed the American Founders’ vision for a self-governing people, in a society where leaders and average citizens share essentially the same understanding of reality—of what simply makes sense. But today our confidence in the value and reliability of common sense has been badly shaken. Deep thinkers have rejected it. Elites have learned to disdain it. We’re told that we have moved into a more sophisticated world, where common sense is passé and the very concept of truth is outmoded. Indeed, the Oxford Dictionaries selected “post-truth” as the Word of the Year for 2016. Do we actually live in a post-truth reality? Have we moved beyond common sense? Can we? In this book, Robert Curry exposes the absurdity of the attacks on common sense, and demonstrates that we still live and move in the realm of common sense in our every waking moment. Drawing from philosophy and literature, science and psychiatry, Reclaiming Common Sense helps us regain our trust in the “superpower” we all have in common, while reminding us that we cannot get along without it.
