Einstein's Theory of Relativity
by Max BornA book in which one great mind explains the work of another great mind in terms comprehensible to the layman is a significant achievement. This is such a book. Max Born is a Nobel Laureate (1955) and one of the world's great physicists: in this book he analyzes and interprets the theory of Einsteinian relativity. The result is undoubtedly the most lucid and insightful of all the books that have been written to explain the revolutionary theory that marked the end of the classical and the beginning of the modern era of physics.The author follows a quasi-historical method of presentation. The book begins with a review of the classical physics, covering such topics as origins of space and time measurements, geometric axioms, Ptolemaic and Copernican astronomy, concepts of equilibrium and force, laws of motion, inertia, mass, momentum and energy, Newtonian world system (absolute space and absolute time, gravitation, celestial mechanics, centrifugal forces, and absolute space), laws of optics (the corpuscular and undulatory theories, speed of light, wave theory, Doppler effect, convection of light by matter), electrodynamics (including magnetic induction, electromagnetic theory of light, electromagnetic ether, electromagnetic laws of moving bodies, electromagnetic mass, and the contraction hypothesis). Born then takes up his exposition of Einstein's special and general theories of relativity, discussing the concept of simultaneity, kinematics, Einstein's mechanics and dynamics, relativity of arbitrary motions, the principle of equivalence, the geometry of curved surfaces, and the space-time continuum, among other topics. Born then points out some predictions of the theory of relativity and its implications for cosmology, and indicates what is being sought in the unified field theory.This account steers a middle course between vague popularizations and complex scientific presentations. This is a careful discussion of principles stated in thoroughly acceptable scientific form, yet in a manner that makes it possible for the reader who has no scientific training to understand it. Only high school algebra has been used in explaining the nature of classical physics and relativity, and simple experiments and diagrams are used to illustrate each step. The layman and the beginning student in physics will find this an immensely valuable and usable introduction to relativity. This Dover 1962 edition was greatly revised and enlarged by Dr. Born.
Einstein's Theory of Unified Fields (Routledge Library Editions: 20th Century Science)
by Marie Antoinette TonnelatFirst published in1966, here is presented a comprehensive overview of one of the most elusive scientific speculations by the pre-eminent genius of the 20th century. The theory is viewed by some scientists with deep suspicion, by others with optimism, but all agree that it represents an extreme challenge. As the author herself affirms, this work is not intended to be a complete treatise or ‘didactic exposition’ of the theory of unified fields, but rather a tool for further study, both by students and professional physicists. Dealing with all the major areas of research which together comprise the development of a working model, the author ranges over conservation equations, variational principles, solutions of spherical symmetry, and treats a wide selection of Einstein’s own equations. The final chapter indicates problems associated with the unified field theory, in particular the energy-momentum tensor and geodesics.
Einstein's Tutor: The Story of Emmy Noether and the Invention of Modern Physics
by Lee PhillipsA revelatory story of the woman who made foundational contributions to science and mathematics and persevered in the face of discrimination. Emmy Noether's mathematical genius enabled Einstein to bring his General Theory of Relativity–the basis of our current theory of gravity–to fruition. On a larger scale, what came to be known as &“Noether&’s Theorem&”—called by a Nobel laureate &“the single most profound result in all of physics&”—supplied the basis for the most accurate theory in the history of physics, the Standard Model, which forms our modern theory of matter. Noether&’s life story is equally important and revelatory in understanding the pernicious nature of sexual prejudice in the sciences, revealing the shocking discrimination against one of the true intellectual giants of the twentieth century, a woman effectively excluded from the opportunities given to her male counterparts. Noether&’s personality and optimistic spirit, as Lee Phillips reveals, enabled her unique genius to persevere and arrive at insights that still astonish those who encounter them a century later.
Einstein's Unfinished Revolution: The Search for What Lies Beyond the Quantum
by Lee SmolinA daring new vision of the quantum universe, and the scandals controversies, and questions that may illuminate our future--from Canada's leading mind on contemporary physics.Quantum physics is the golden child of modern science. It is the basis of our understanding of atoms, radiation, and so much else, from elementary particles and basic forces to the behaviour of materials. But for a century it has also been the problem child of science, plagued by intense disagreements between its intellectual giants, from Albert Einstein to Stephen Hawking, over the strange paradoxes and implications that seem like the stuff of fantasy. Whether it's Schrödinger's cat--a creature that is simultaneously dead and alive--or a belief that the world does not exist independently of our observations of it, quantum theory is what challenges our fundamental assumptions about our reality. In Einstein's Unfinished Revolution, globally renowned theoretical physicist Lee Smolin provocatively argues that the problems which have bedeviled quantum physics since its inception are unsolved for the simple reason that the theory is incomplete. There is more, waiting to be discovered. Our task--if we are to have simple answers to our simple questions about the universe we live in--must be to go beyond it to a description of the world on an atomic scale that makes sense. In this vibrant and accessible book, Smolin takes us on a journey through the basics of quantum physics, introducing the stories of the experiments and figures that have transformed the field, before wrestling with the puzzles and conundrums that they present. Along the way, he illuminates the existing theories about the quantum world that might solve these problems, guiding us toward his own vision that embraces common sense realism. If we are to have any hope of completing the revolution that Einstein began nearly a century ago, we must go beyond quantum mechanics as we know it to find a theory that will give us a complete description of nature. In Einstein's Unfinished Revolution, Lee Smolin brings us a step closer to resolving one of the greatest scientific controversies of our age.

Einstein's Unfinished Symphony: The Story of a Gamble, Two Black Holes, and a New Age of Astronomy
by Marcia BartusiakThis updated edition of the New York Times Notable Book recounts the long hunt for Einstein&’s predicted gravitational waves—and celebrates their discovery. In February 2016, astronomers announced that they had verified the last remaining prediction of Einstein&’s general theory of relativity—vibrations in space-time, called gravitational waves. Humanity can now tune in to a cosmic orchestra. We have heard the chirp of two black holes dancing toward a violent union. We will hear the cymbal crashes from exploding stars, the periodic drumbeats from swiftly rotating pulsars, and maybe even the echoes from the Big Bang itself. More than a decade earlier, Marcia Bartusiak chronicled the gamble taken by astronomers who were determined to prove Einstein right. In their quest to detect gravitational waves, they built the Laser Interferometer Gravitational-Wave Observatory (LIGO) detectors, the most accurate measuring devices ever created. In this updated edition, Bartusiak brings the story to a thrilling close with the triumphant discovery of gravitational waves made with the LIGO. "An important, multifaceted scientific story…part theoretical physics, part astronomy, part experimental physics, part engineering."—James Ryerson, New York Times Book Review
Einstein's Unification
by Jeroen Van DongenWhy did Einstein tirelessly study unified field theory for more than 30 years? In this book, the author argues that Einstein believed he could find a unified theory of all of nature's forces by repeating the methods he thought he had used when he formulated general relativity. The book discusses Einstein's route to the general theory of relativity, focusing on the philosophical lessons that he learnt. It then addresses his quest for a unified theory for electromagnetism and gravity, discussing in detail his efforts with Kaluza-Klein and, surprisingly, the theory of spinors. From these perspectives, Einstein's critical stance towards the quantum theory comes to stand in a new light. This book will be of interest to physicists, historians and philosophers of science.
Einstein's War: How Relativity Triumphed Amid the Vicious Nationalism of World War I
by Matthew StanleyKIRKUS STARRED REVIEWPUBLISHER'S WEEKLY STARRED REVIEWThe birth of a world-changing idea in the middle of a bloodbath Einstein’s War is a riveting exploration of both the beauty of scientific creativity and enduring horrors of human nature. These two great forces battle in a story that culminates with a victory now a century old, the mind bending theory of general relativity. Few recognize how the Great War, the industrialized slaughter that bled Europe from 1914 to 1918, shaped Einstein’s life and work. While Einstein never held a rifle, he formulated general relativity blockaded in Berlin, literally starving. He lost 50 pounds in three months, unable to communicate with his most important colleagues. Some of those colleagues fought against rabid nationalism; others were busy inventing chemical warfare—being a scientist trapped you in the power plays of empire. Meanwhile, Einstein struggled to craft relativity and persuade the world that it was correct. This was, after all, the first complete revision of our conception of the universe since Isaac Newton, and its victory was far from sure. Scientists seeking to confirm Einstein’s ideas were arrested as spies. Technical journals were banned as enemy propaganda. Colleagues died in the trenches. Einstein was separated from his most crucial ally by barbed wire and U-boats. This ally was the Quaker astronomer and Cambridge don A.S. Eddington who would go on to convince the world of the truth of relativity and the greatness of Einstein. In May of 1919, when Europe was still in chaos from the war, Eddington led a globe-spanning expedition to catch a fleeting solar eclipse for a rare opportunity to confirm Einstein’s bold prediction that light has weight. It was the result of this expedition—the proof of relativity, as many saw it—that put Einstein on front pages around the world. Matthew Stanley’s epic tale is a celebration of how bigotry and nationalism can be defeated, and of what science can offer when they are.
Einstein's Wife: The Real Story of Mileva Einstein-Mari? (The\mit Press Ser.)
by David C. Cassidy Allen EstersonWas Einstein's first wife his uncredited coauthor, unpaid assistant, or his unacknowledged helpmeet? The real “Mileva Story.”Albert Einstein's first wife, Mileva Einstein-Marić, was forgotten for decades. When a trove of correspondence between them beginning in their student days was discovered in 1986, her story began to be told. Some of the tellers of the “Mileva Story” made startling claims: that she was a brilliant mathematician who surpassed her husband, and that she made uncredited contributions to his most celebrated papers in 1905, including his paper on special relativity. This book, based on extensive historical research, uncovers the real “Mileva Story.” Mileva was one of the few women of her era to pursue higher education in science; she and Einstein were students together at the Zurich Polytechnic. Mileva's ambitions for a science career, however, suffered a series of setbacks—failed diploma examinations, a disagreement with her doctoral dissertation adviser, an out-of-wedlock pregnancy by Einstein. She and Einstein married in 1903 and had two sons, but the marriage failed. Was Mileva her husband's uncredited coauthor, unpaid assistant, or his essential helpmeet? It's tempting to believe that she was her husband's secret collaborator, but the authors of Einstein's Wife look at the actual evidence, and a chapter by Ruth Lewin Sime offers important historical context. The story they tell is that of a brave and determined young woman who struggled against a variety of obstacles at a time when science was not very welcoming to women.
Einstein, Picasso: Space, Time And The Beauty That Causes Havoc
by Arthur J. MillerThe most important scientist of the twentieth century and the most important artist had their periods of greatest creativity almost simultaneously and in remarkably similar circumstances. This fascinating parallel biography of Albert Einstein and Pablo Picasso as young men examines their greatest creations-Picasso's Les Demoiselles d'Avignon and Einstein's special theory of relativity. Miller shows how these breakthroughs arose not only from within their respective fields but from larger currents in the intellectual culture of the times. Ultimately, Miller shows how Einstein and Picasso, in a deep and important sense, were both working on the same problem.
Einstein, Relativity and Absolute Simultaneity (Routledge Studies in Contemporary Philosophy)
by William Lane Craig Quentin SmithEinstein, Relativity and Absolute Simultaneity is an anthology of original essays by an international team of leading philosophers and physicists who have come together to reassess the contemporary paradigm of the relativistic concept of time. A great deal has changed since 1905 when Einstein proposed his Special Theory of Relativity, and this book offers a fresh reassessment of Special Relativity’s relativistic concept of time in terms of epistemology, metaphysics, and physics.
Einstein, Tagore and the Nature of Reality: Literary And Philosophical Reflections (Routledge Studies in the Philosophy of Mathematics and Physics)
by Partha GhoseThe nature of reality has been a long-debated issue among scientists and philosophers. In 1930, Rabindranath Tagore and Albert Einstein had a long conversation on the nature of reality. This conversation has been widely quoted and discussed by scientists, philosophers and scholars from the literary world. The important question that Tagore and Einstein discussed was whether the world is a unity dependent on humanity, or the world is a reality independent on the human factor. Einstein took the stand adopted by Western philosophers and mathematicians, namely that reality is something independent of the mind and the human factor. Tagore, on the other hand, adopted the opposite view. Nevertheless, both Einstein and Tagore claimed to be realists despite the fundamental differences between their conceptions of reality. Where does the difference lie? Can it be harmonized at some deeper level? Can Wittgenstein, for example, be a bridge between the two views? This collection of essays explores these two fundamentally different conceptions of the nature of reality from the perspectives of theories of space-time, quantum theory, general philosophy of science, cognitive science and mathematics.

Einstein: A Biography
by Jurgen Neffe Shelley Frischinteresting book. There several German and Austrian names in the text but the book is absolutely intriguing.
Einstein: A Biography
by Jürgen NeffeAlbert Einstein is an icon of the twentieth century. Born in Ulm, Germany, in 1879, he is most famous for his theory of relativity. He also made enormous contributions to quantum mechanics and cosmology, and for his work he was awarded the Nobel Prize in 1921. A self-pronounced pacifist, humanist, and, late in his life, democratic socialist, Einstein was also deeply concerned with the social impact of his discoveries. Much of Einstein's life is shrouded in legend. From popular images and advertisements to various works of theater and fiction, he has come to signify so many things. In Einstein: A Biography, Jürgen Neffe presents a clear and probing portrait of the man behind the myth. Unearthing new documents, including a series of previously unknown letters from Einstein to his sons, which shed new light on his role as a father, Neffe paints a rich portrait of the tumultuous years in which Einstein lived and worked. And with a background in the sciences, he describes and contextualizes Einstein's enormous contributions to our scientific legacy.Einstein, a breakout bestseller in Germany, is sure to be a classic biography of the man and proverbial genius who has been called "the brain of the [twentieth] century."
Einstein: An Intimate Study of a Great Man
by Dimitri Marianoff Palma WayneEinstein: An Intimate Study of a Great Man, first published in 1944, recounts the personal life of physicist Albert Einstein (1879-1955). The book was written by Einstein’s son-in-law, who married his daughter Margot in Berlin in 1930. Einstein was a simple, direct man, but remains today larger-than-life, and as author Marianoff writes, “Einstein’s life is not an exciting one. It is not filled with the rush and sweep of spectacular adventures. It has none of the scope and danger of the explorer, who freezes and suffers and agonizes in his search. It is not filled with the stir and headiness of eventful, flamboyant episodes. It is not a colorful panorama of the human pilgrimage...It has no color at all except the color of greatness...It is a mighty epic journey of science—a steady, breathtaking march whose heroic altitude is of such heights that it precludes the ecstatic language so often applied to singular human endeavors...It has no thrill in it, except the thrill of having changed the tide of man’s history and created new channels for his growth...It has no drama in it, except the overpowering drama of a conquest so immeasurable that as long as man remains on earth he will have benefited by it.”
Einstein: His Life and Universe (Great Thinkers Ser.)
by Walter IsaacsonBy the author of the acclaimed bestsellers Benjamin Franklin and Steve Jobs, this is the definitive biography of Albert Einstein. How did his mind work? What made him a genius? Isaacson’s biography shows how his scientific imagination sprang from the rebellious nature of his personality. His fascinating story is a testament to the connection between creativity and freedom. Based on newly released personal letters of Einstein, this book explores how an imaginative, impertinent patent clerk—a struggling father in a difficult marriage who couldn’t get a teaching job or a doctorate—became the mind reader of the creator of the cosmos, the locksmith of the mysteries of the atom, and the universe. His success came from questioning conventional wisdom and marveling at mysteries that struck others as mundane. This led him to embrace a morality and politics based on respect for free minds, free spirits, and free individuals. These traits are just as vital for this new century of globalization, in which our success will depend on our creativity, as they were for the beginning of the last century, when Einstein helped usher in the modern age.
Einstein: Su vida y su universo
by Walter IsaacsonLa biografía definitiva de Albert Einstein, uno de los iconos del siglo XX y su mayor genio. Albert Einstein es uno de los científicos más importantes de la historia y un icono del siglo XX. ¿Cómo funcionaba su mente? ¿Qué le hizo un genio? ¿Cómo era el hombre detrás de la celebridad? Walter Isaacson, que tuvo acceso a los archivos de Einstein, ofrece un extraordinario retrato del personaje y de su época, así como un fascinante relato de su vida. A partir de su correspondencia privada, cuenta cómo un funcionario de patentes imaginativo e impertinente (un mal padre con un matrimonio complicado, incapaz de conseguir un empleo en la universidad ni un doctorado) logró desvelar los secretos del cosmos y comprender los misterios del átomo y del universo. Su creatividad estaba ligada a su rebeldía. Su éxito se basó en cuestionar las verdades aceptadas y en asombrarse ante cuestiones que otros consideraban mundanas. Reseñas: «Espléndida, un gran trabajo de investigación con mucho material inédito. Una obra fundamental y definitiva.»Amir D. Aczel, The Boston Globe «Walter Isaacson ha logrado un retrato completo de Einstein.

Einstein’s Brain: Genius, Culture, and Social Networks
by Sal RestivoThis book reviews the research on Einstein’s brain from a sociological perspective and in the context of the social brain paradigm. Instead of “Einstein, the genius of geniuses” standing on the shoulders of giants, Restivo proposes a concept of Einstein the social being standing on the shoulders of social networks. Rather than challenging Einstein’s uniqueness or the uniqueness of his achievements, the book grounds Einstein and his achievements in a social ecology opposed to the myths of the “I,” individualism, and the very idea of “genius.” “Einstein” is defined by the particular configuration of social networks that he engaged as his life unfolded, not by biological inheritances.

Eisengruppe: Eine Reise durch das Periodensystem (essentials)
by Hermann SiciusHermann Sicius stellt ausf#65533;hrlich die Elemente der achten Nebengruppe (Eisen, Ruthenium, Osmium und Hassium) vor, die allesamt harte, hochschmelzende Metalle sind. Auch bei den Platinmetallen Ruthenium und Osmium wirkt sich noch die Lanthanoidenkontraktion aus. In ihren physikalischen Eigenschaften unterscheiden sich Ruthenium und Osmium relativ deutlich, aber nur wenig in Bezug auf ihre chemischen Eigenschaften. Eisen weicht dagegen hinsichtlich seines unedlen Charakters und niedrigeren Dichten, Schmelz- und Siedepunkten schon deutlich ab. Die Elemente dieser Gruppe k#65533;nnen maximal acht #65533;u#65533;ere Valenzelektronen abgeben, um eine stabile Elektronenkonfiguration zu erreichen. Die Entdeckung des Eisens - eines der h#65533;ufigsten Elemente #65533;berhaupt - erfolgte schon 3. 000 v. Chr. in Mesopotamien, wogegen Osmium und Ruthenium als sehr seltene Elemente in der ersten H#65533;lfte des 19. Jahrhunderts entdeckt wurden. Die k#65533;nstliche Erstdarstellung von Atomen des Hassiums gelang 1984.
