To those of us who are not mathematicians or physicists, Einstein’s theory of relativity often seems incomprehensible, exotic, and 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 and geometry can both grasp and apply the theory. Styer starts off slowly and proceeds carefully, explaining the concepts undergirding relativity in language comprehensible to nonscientists yet precise and accurate enough to satisfy the most demanding professional. He demonstrates how the theory applies to various real-life situations with easy equations and simple, clear diagrams. Styer's classroom-tested method of conveying the core ideas of relativity—the relationship among and between time, space, and motion and the behavior of light—encourages questions and 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 and its attendant principles, an example-based exploration of relativity, and explanations of how and why gravity and spacetime are linked. By demonstrating relativity with practical applications, Styer teaches us to truly understand and appreciate its importance, beauty, and usefulness. Featuring worked and end-of-chapter problems and illustrated, nontechnical explanations of core concepts, while dotted throughout with questions and answers, puzzles, and 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, and materials to stimulate further exploration.

A “beautifully written, heartbreaking” (S. J. Watson) debut novel about a gifted boy who discovers the truth about his past, his overprotective single mother who tries desperately to shield him from it, and the father he has never met who has unexpectedly returned. “Original, compassionate, cleverly plotted, and genuinely difficult to put down.” –Graeme Simsion, New York Times bestselling author of The Rosie Project Twelve-year-old Ethan Forsythe, an exceptionally talented boy obsessed with physics and astronomy, has been raised alone by his mother in Sydney, Australia. Claire, a former professional ballerina, has been a wonderful parent to Ethan, but he’s becoming increasingly curious about his father’s absence in his life. Claire is fiercely protective of her talented, vulnerable son—and of her own feelings. But when Ethan falls ill, tied to a tragic event that occurred during his infancy, her tightly-held world is split open. Thousands of miles away on the western coast of Australia, Mark is trying to forget about the events that tore his family apart, but an unexpected call forces him to confront his past and return home. When Ethan secretly intercepts a letter from Mark to Claire, he unleashes long-suppressed forces that—like gravity—pull the three together again, testing the limits of love and forgiveness. Told from the alternating points of view of Ethan and each of his parents, Relativity is a poetic and soul-searing exploration of unbreakable bonds, irreversible acts, the limits of science, and the magnitude of love.
To get the best answer-in business, in life-you have to ask the best possible question. Innovation expert Warren Berger shows that ability is both an art and a science. It may be the most underappreciated tool at our disposal, one we learn to use well in infancy-and then abandon as we grow older. Critical to learning, innovation, success, even to happiness-yet often discouraged in our schools and workplaces-it can unlock new business opportunities and reinvent industries, spark creative insights at many levels, and provide a transformative new outlook on life. It is the ability to question-and to do so deeply, imaginatively, and “beautifully.” In this fascinating exploration of the surprising power of questioning, innovation expert Warren Berger reveals that powerhouse businesses like Google, Nike, and Netflix, as well as hot Silicon Valley startups like Pandora and Airbnb, are fueled by the ability to ask fundamental, game-changing questions. But Berger also shares human stories of people using questioning to solve everyday problems-from “How can I adapt my career in a time of constant change?” to “How can I step back from the daily rush and figure out what really makes me happy?” By showing how to approach questioning with an open, curious mind and a willingness to work through a series of “Why,” “What if,” and “How” queries, Berger offers an inspiring framework of how we can all arrive at better solutions, fresh possibilities, and greater success in business and life.
The untold story of Albert Einstein's role as the father of quantum theory Einstein and the Quantum reveals for the first time the full significance of Albert Einstein's contributions to quantum theory. Einstein famously rejected quantum mechanics, observing that God does not play dice. But, in fact, he thought more about the nature of atoms, molecules, and the emission and absorption of light—the core of what we now know as quantum theory—than he did about relativity. A compelling blend of physics, biography, and the history of science, Einstein and the Quantum shares the untold story of how Einstein—not Max Planck or Niels Bohr—was the driving force behind early quantum theory. It paints a vivid portrait of the iconic physicist as he grappled with the apparently contradictory nature of the atomic world, in which its invisible constituents defy the categories of classical physics, behaving simultaneously as both particle and wave. And it demonstrates how Einstein's later work on the emission and absorption of light, and on atomic gases, led directly to Erwin Schrödinger's breakthrough to the modern form of quantum mechanics. The book sheds light on why Einstein ultimately renounced his own brilliant work on quantum theory, due to his deep belief in science as something objective and eternal.
Newton's Laws held for 300 years until Einstein developed the 'special theory of relativity' in 1905. Experiments done since then show anomalies in that theory. This book starts with a description of the special theory of relativity. It is shown that Einstein was not the first to derive the famous equation E = mc2, which has become synonymous with his name. Next, experimental evidence that cannot be explained by special relativity is given. In the light of this evidence, the two basic postulates of the special theory of relativity on the behaviour of light are shown to be untenable. A new theory (universal relativity) is developed, which conforms to the experimental evidence. The movement of a conductor near a pole of a magnet and the movement of that pole near the conductor does not always give the same result. It has been claimed that this contradicts relativity theory. Experiments described in this book show that it is not special relativity but another basic law of physics that is contradicted - Faraday's Law. The Big Bang theory of the beginning of the universe is questioned and an alternative proposed. The source of much of the mysterious missing 'dark matter' that has been sought for decades by astronomers is located. An explanation of the shapes of some galaxies is proffered. This book presents an alternative to Einstein's special theory of relativity, solves many problems left unanswered by special relativity, gives a better fit to many phenomena and experimental data and is more philosophically appealing. It is recommended to all people interested in fundamental issues of physics and cosmology. Professor Andre Assis, Brazil The book treats its subject properly, not just as an impersonal set of equations, but rather as a developing saga full of human triumph and failure. One learns from both experimental results and simple logical argument that all is not well with modern physics.

In It's About Time, N. David Mermin asserts that relativity ought to be an important part of everyone's education--after all, it is largely about time, a subject with which all are familiar. The book reveals that some of our most intuitive notions about time are shockingly wrong, and that the real nature of time discovered by Einstein can be rigorously explained without advanced mathematics. This readable exposition of the nature of time as addressed in Einstein's theory of relativity is accessible to anyone who remembers a little high school algebra and elementary plane geometry. The book evolved as Mermin taught the subject to diverse groups of undergraduates at Cornell University, none of them science majors, over three and a half decades. Mermin's approach is imaginative, yet accurate and complete. Clear, lively, and informal, the book will appeal to intellectually curious readers of all kinds, including even professional physicists, who will be intrigued by its highly original approach.
This thoroughly up-to-date, highly accessible overview covers microgravity, collider accelerators, satellite probes, neutron detectors, radioastronomy, and pulsars.
"This beautiful little book is certainly suitable for anyone who has had an introductory course in physics and even for some who have not."—Joshua N.

The treatment is masterful, continual emphasis being placed on careful discussion and motivation, with the aim of showing how physicists think and develop their ideas."—Choice
PREFACE. THE Author of this very practical treatise on Scotch Loch - Fishing desires clearly that it may be of use to all who had it. He does not pretend to have written anything new, but to have attempted to put what he has to say in as readable a form as possible. Everything in the way of the history and habits of fish has been studiously avoided, and technicalities have been used as sparingly as possible. The writing of this book has afforded him pleasure in his leisure moments, and that pleasure would be much increased if he knew that the perusal of it would create any bond of sympathy between himself and the angling community in general. This section is interleaved with blank shects for the readers notes. The Author need hardly say that any suggestions addressed to the case of the publishers, will meet with consideration in a future edition. We do not pretend to write or enlarge upon a new subject. Much has been said and written-and well said and written too on the art of fishing but loch-fishing has been rather looked upon as a second-rate performance, and to dispel this idea is one of the objects for which this present treatise has been written. Far be it from us to say anything against fishing, lawfully practised in any form but many pent up in our large towns will bear us out when me say that, on the whole, a days loch-fishing is the most convenient. One great matter is, that the loch-fisher is depend- ent on nothing but enough wind to curl the water, -and on a large loch it is very seldom that a dead calm prevails all day, -and can make his arrangements for a day, weeks beforehand whereas the stream- fisher is dependent for a good take on the state of the water and however pleasant and easy it may be for one living near the banks of a good trout stream or river, it is quite another matter to arrange for a days river-fishing, if one is looking forward to a holiday at a date some weeks ahead. Providence may favour the expectant angler with a good day, and the water in order but experience has taught most of us that the good days are in the minority, and that, as is the case with our rapid running streams, -such as many of our northern streams are, -the water is either too large or too small, unless, as previously remarked, you live near at hand, and can catch it at its best. A common belief in regard to loch-fishing is, that the tyro and the experienced angler have nearly the same chance in fishing, -the one from the stern and the other from the bow of the same boat. Of all the absurd beliefs as to loch-fishing, this is one of the most absurd. Try it. Give the tyro either end of the boat he likes give him a cast of ally flies he may fancy, or even a cast similar to those which a crack may be using and if he catches one for every three the other has, he may consider himself very lucky. Of course there are lochs where the fish are not abundant, and a beginner may come across as many as an older fisher but we speak of lochs where there are fish to be caught, and where each has a fair chance. Again, it is said that the boatman has as much to do with catching trout in a loch as the angler. Well, we dont deny that. In an untried loch it is necessary to have the guidance of a good boatman but the same argument holds good as to stream-fishing...
