This book provides a lively and visual introduction to Einstein's theory of relativity. It begins by introducing spacetime, in the familiar context of low velocities. It then shows how Einstein's theory forces us to understand time in a new way. Paradoxes and puzzles are introduced and resolved, and the book culminates in a thorough unfolding of the relation between mass and energy.

This book unfolds the subject of Relativity for undergraduate students of physics. It fills a gap between introductory descriptions and texts for researchers. Assuming almost no prior knowledge, it allows the student to handle all the Relativity needed for a university course, with explanations as simple, thorough, and engaging as possible.

An annotated facsimile edition of Einstein's handwritten manuscript on the foundations of general relativity This richly annotated facsimile edition of "The Foundation of General Relativity" introduces a new generation of readers to Albert Einstein's theory of gravitation. Written in 1915, this remarkable document is a watershed in the history of physics and an enduring testament to the elegance and precision of Einstein's thought. Presented here is a beautiful facsimile of Einstein's original handwritten manuscript, along with its English translation and an insightful page-by-page commentary that places the work in historical and scientific context. Hanoch Gutfreund and Jürgen Renn's concise introduction traces Einstein's intellectual odyssey from special to general relativity, and their essay "The Charm of a Manuscript" provides a delightful meditation on the varied afterlife of Einstein's text. Featuring a foreword by John Stachel, this handsome edition also includes a biographical glossary of the figures discussed in the book, a comprehensive bibliography, suggestions for further reading, and numerous photos and illustrations throughout.

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.

“One of the best popular accounts of how Einstein and his followers have been trying to explain the universe for decades” (Kirkus Reviews, starred review). Physicists have been exploring, debating, and questioning the general theory of relativity ever since Albert Einstein first presented it in 1915. This has driven their work to unveil the universe’s surprising secrets even further, and many believe more wonders remain hidden within the theory’s tangle of equations, waiting to be exposed. In this sweeping narrative of science and culture, an astrophysicist brings general relativity to life through the story of the brilliant physicists, mathematicians, and astronomers who have taken up its challenge. For these scientists, the theory has been both a treasure trove and an enigma. Einstein’s theory, which explains the relationships among gravity, space, and time, is possibly the most perfect intellectual achievement of modern physics—yet studying it has always been a controversial endeavor. Relativists were the target of persecution in Hitler’s Germany, hounded in Stalin’s Russia, and disdained in 1950s America. Even today, PhD students are warned that specializing in general relativity will make them unemployable. Still, general relativity has flourished, delivering key insights into our understanding of the origin of time and the evolution of all the stars and galaxies in the cosmos. Its adherents have revealed what lies at the farthest reaches of the universe, shed light on the smallest scales of existence, and explained how the fabric of reality emerges. Dark matter, dark energy, black holes, and string theory are all progeny of Einstein’s theory. In the midst of a momentous transformation in modern physics, as scientists look farther and more clearly into space than ever before, The Perfect Theory exposes the greater relevance of general relativity, showing us where it started, where it has led—and where it can still take us.

With wit, colour and clarity, What A Wonderful World quickly and painlessly brings us up to speed on how the world of the 21st century works. From economics to physics and biology to philosophy, Marcus Chown explains the complex forces that shape our universe. Why do we breathe? What is money? How does the brain work? Why did life invent sex? Does time really exist? How does capitalism work - or not, as the case may be? Where do mountains come from? How do computers work? How did humans get to dominate the Earth? Why is there something rather than nothing? In What a Wonderful World, Marcus Chown, bestselling author of Quantum Theory Cannot Hurt You and the Solar System app, uses his vast scientific knowledge and deep understanding of extremely complex processes to answer simple questions about the workings of our everyday lives. Lucid, witty and hugely entertaining, it explains the basics of our essential existence, stopping along the way to show us why the Atlantic is widening by a thumbs' length each year, how money permits trade to time travel why the crucial advantage humans had over Neanderthals was sewing and why we are all living in a giant hologram.

INSTANT NEW YORK TIMES BESTSELLER “Most appealing... technical accuracy and lightness of tone... Impeccable.”—Wall Street Journal “A porthole into another world.”—Scientific American “Brings science dissemination to a new level.”—Science The most trusted explainer of the most mind-boggling concepts pulls back the veil of mystery that has too long cloaked the most valuable building blocks of modern science. Sean Carroll, with his genius for making complex notions entertaining, presents in his uniquely lucid voice the fundamental ideas informing the modern physics of reality. Physics offers deep insights into the workings of the universe but those insights come in the form of equations that often look like gobbledygook. Sean Carroll shows that they are really like meaningful poems that can help us fly over sierras to discover a miraculous multidimensional landscape alive with radiant giants, warped space-time, and bewilderingly powerful forces. High school calculus is itself a centuries-old marvel as worthy of our gaze as the Mona Lisa. And it may come as a surprise the extent to which all our most cutting-edge ideas about black holes are built on the math calculus enables. No one else could so smoothly guide readers toward grasping the very equation Einstein used to describe his theory of general relativity. In the tradition of the legendary Richard Feynman lectures presented sixty years ago, this book is an inspiring, dazzling introduction to a way of seeing that will resonate across cultural and generational boundaries for many years to come.
