Ken Ford’s mission is to help us understand the “great ideas” of quantum physics—ideas such as wave-particle duality, the uncertainty principle, superposition, and conservation. These fundamental concepts provide the structure for 101 Quantum Questions, an authoritative yet engaging book for the general reader in which every question and answer brings out one or more basic features of the mysterious world of the quantum—the physics of the very small.

Nuclear researcher and master teacher, Ford covers everything from quarks, quantum jumps, and what causes stars to shine, to practical applications ranging from lasers and superconductors to light-emitting diodes. Ford’s lively answers are enriched by Paul Hewitt's drawings, numerous photos of physicists, and anecdotes, many from Ford’s own experience. Organized for cover-to-cover reading, 101 Quantum Questions also is great for browsing.

Some books focus on a single subject such as the standard model of particles, or string theory, or fusion energy. This book touches all those topics and more, showing us that disparate natural phenomena, as well as a host of manmade inventions, can be understood in terms of a few key ideas. Yet Ford does not give us simplistic explanations. He assumes a serious reader wanting to gain real understanding of the essentials of quantum physics.

Ken Ford's other books include The Quantum World: Quantum Physics for Everyone (Harvard 2004), which Esquire magazine recommended as the best way to gain an understanding of quantum physics. Ford's new book, a sequel to the earlier one, makes the quantum world even more accessible.

For Albert Einstein, 1905 was a remarkable year. It was also a miraculous year for the history and future of science. In six short months, from March through September of that year, Einstein published five papers that would transform our understanding of nature. This unparalleled period is the subject of John Rigden's book, which deftly explains what distinguishes 1905 from all other years in the annals of science, and elevates Einstein above all other scientists of the twentieth century.

Rigden chronicles the momentous theories that Einstein put forth beginning in March 1905: his particle theory of light, rejected for decades but now a staple of physics; his overlooked dissertation on molecular dimensions; his theory of Brownian motion; his theory of special relativity; and the work in which his famous equation, E = mc2, first appeared. Through his lucid exposition of these ideas, the context in which they were presented, and the impact they had--and still have--on society, Rigden makes the circumstances of Einstein's greatness thoroughly and captivatingly clear. To help readers understand how these ideas continued to develop, he briefly describes Einstein's post-1905 contributions, including the general theory of relativity.

One hundred years after Einstein's prodigious accomplishment, this book invites us to learn about ideas that have influenced our lives in almost inconceivable ways, and to appreciate their author's status as the standard of greatness in twentieth-century science.

The first comprehensive philosophical and historical account of the experimental foundations of Niels Bohr’s practice of physics.

Niels Bohr was a central figure in quantum physics, well known for his work on atomic structure and his contributions to the Copenhagen interpretation of quantum mechanics. In this book, philosopher of science Slobodan Perović explores the way Bohr practiced and understood physics, and analyzes its implications for our understanding of modern science. Perović develops a novel approach to Bohr’s understanding of physics and his method of inquiry, presenting an exploratory symbiosis of historical and philosophical analysis that uncovers the key aspects of Bohr’s philosophical vision of physics within a given historical context.

To better understand the methods that produced Bohr’s breakthrough results in quantum phenomena, Perović clarifies the nature of Bohr’s engagement with the experimental side of physics and lays out the basic distinctions and concepts that characterize his approach. Rich and insightful, Perović’s take on the early history of quantum mechanics and its methodological ramifications sheds vital new light on one of the key figures of modern physics.

A sweeping account of the century of experimentation that confirmed Einstein’s general theory of relativity, bringing to life the science and scientists at the origins of relativity, the development of radio telescopes, the discovery of black holes and quasars, and the still unresolved place of gravity in quantum theory.

Albert Einstein did nothing of note on May 29, 1919, yet that is when he became immortal. On that day, astronomer Arthur Eddington and his team observed a solar eclipse and found something extraordinary: gravity bends light, just as Einstein predicted. The finding confirmed the theory of general relativity, fundamentally changing our understanding of space and time.

A century later, another group of astronomers is performing a similar experiment on a much larger scale. The Event Horizon Telescope, a globe-spanning array of radio dishes, is examining space surrounding Sagittarius A*, the supermassive black hole at the center of the Milky Way. As Ron Cowen recounts, the foremost goal of the experiment is to determine whether Einstein was right on the details. Gravity lies at the heart of what we don’t know about quantum mechanics, but tantalizing possibilities for deeper insight are offered by black holes. By observing starlight wrapping around Sagittarius A*, the telescope will not only provide the first direct view of an event horizon—a black hole’s point of no return—but will also enable scientists to test Einstein’s theory under the most extreme conditions.

Gravity’s Century shows how we got from the pivotal observations of the 1919 eclipse to the Event Horizon Telescope, and what is at stake today. Breaking down the physics in clear and approachable language, Cowen makes vivid how the quest to understand gravity is really the quest to comprehend the universe.

From the celebrated author of Quantum Mechanics and Experience comes an original and exhilarating attempt at making sense of the strange laws of quantum mechanics.

A century ago, a brilliant circle of physicists around Niels Bohr argued that the search for an objective, realistic, and mechanical picture of the inner workings of the atom—the kind of picture that had previously been an ideal of classical physics—was doomed to fail. Today, there is widespread agreement among philosophers and physicists that those arguments were wrong. However, the question of what that picture might look like, and how it might fit into a comprehensive picture of physical reality, remains unsettled.

In A Guess at the Riddle, philosopher David Z Albert argues that the distinctively strange features of quantum mechanics begin to make sense once we conceive of the wave function, vibrating and evolving in high-dimensional space, as the concrete, fundamental physical “stuff” of the universe. Starting with simple mechanical models, Albert methodically constructs the defining features of quantum mechanics from scratch. He shows how the entire history of our familiar, three-dimensional universe can be discerned in the wave function’s intricate pattern of ripples and whorls. A major new work in the foundations of physics, A Guess at the Riddle is poised to transform our understanding of the basic architecture of the universe.

A concise introduction to the greatest questions of modern cosmology.

What came before the big bang? How will the universe evolve into the future? Will there be a big crunch? Questions like these have no definitive answers, but there are many contending theories. In A Little Book about the Big Bang, physicist and writer Tony Rothman guides expert and uninitiated readers alike through the most compelling mysteries surrounding the nature and origin of the universe.

Cosmologists are busy these days, actively researching dark energy, dark matter, and quantum gravity, all at the foundation of our understanding of space, time, and the laws governing the universe. Enlisting thoughtful analogies and a step-by-step approach, Rothman breaks down what is known and what isn’t and details the pioneering experimental techniques scientists are bringing to bear on riddles of nature at once utterly basic and stunningly complex. In Rothman’s telling, modern cosmology proves to be an intricate web of theoretical predictions confirmed by exquisitely precise observations, all of which make the theory of the big bang one of the most solid edifices ever constructed in the history of science. At the same time, Rothman is careful to distinguish established physics from speculation, and in doing so highlights current controversies and avenues of future exploration.

The idea of the big bang is now almost a century old, yet with each new year comes a fresh enigma. That is scientific progress in a nutshell: every groundbreaking discovery, every creative explanation, provokes new and more fundamental questions. Rothman takes stock of what we have learned and encourages readers to ponder the mysteries to come.

Most observers agree that modern physical theory attempts to provide objective representations of reality. However, the claim that these representations are based on conventional choices is viewed by many as a denial of their objectivity. As a result, objectivity and conventionality in representation are often framed as polar opposites.

Offering a new appraisal of symmetry in modern physics, employing detailed case studies from relativity theory and quantum mechanics, Objectivity, Invariance, and Convention contends that the physical sciences, though dependent on convention, may produce objective representations of reality. Talal Debs and Michael Redhead show that both realists and constructivists have recognized important elements of an understanding of science that may not be contradictory.

The position—“perspectival invariantism”—introduced in this book highlights the shortcomings of existing approaches to symmetry in physics, and, for the constructivist, demonstrates that a dependence on conventions in representation reaches into the domain of the most technical sciences. For the realist, it stands as evidence against the claim that conventionality must undermine objectivity. We can be committed to the existence of a single real ontology while maintaining a cultural view of science.

A renowned philosopher’s final work, illuminating how the logical empiricist tradition has failed to appreciate the role of actual experiments in forming its philosophy of science.

The logical empiricist treatment of physics dominated twentieth-century philosophy of science. But the logical empiricist tradition, for all it accomplished, does not do justice to the way in which empirical evidence functions in modern physics.

In his final work, the late philosopher of science William Demopoulos contends that philosophers have failed to provide an adequate epistemology of science because they have failed to appreciate the tightly woven character of theory and evidence. As a consequence, theory comes apart from evidence. This trouble is nowhere more evident than in theorizing about particle and quantum physics. Arguing that we must consider actual experiments as they have unfolded across history, Demopoulos provides a new epistemology of theories and evidence, albeit one that stands on the shoulders of giants.

On Theories finds clarity in Isaac Newton’s suspicion of mere “hypotheses.” Newton’s methodology lies in the background of Jean Perrin’s experimental investigations of molecular reality and of the subatomic investigations of J. J. Thomson and Robert Millikan. Demopoulos extends this account to offer novel insights into the distinctive nature of quantum reality, where a logico-mathematical reconstruction of Bohrian complementarity meets John Stewart Bell’s empirical analysis of Einstein’s “local realism.” On Theories ultimately provides a new interpretation of quantum probabilities as themselves objectively representing empirical reality.

Measured by the accuracy of its predictions and the scope of its technological applications, quantum mechanics is one of the most successful theories in science—as well as one of the most misunderstood. The deeper meaning of quantum mechanics remains controversial almost a century after its invention. Providing a way past quantum theory’s paradoxes and puzzles, QBism offers a strikingly new interpretation that opens up for the nonspecialist reader the profound implications of quantum mechanics for how we understand and interact with the world.

Short for Quantum Bayesianism, QBism adapts many of the conventional features of quantum mechanics in light of a revised understanding of probability. Bayesian probability, unlike the standard “frequentist probability,” is defined as a numerical measure of the degree of an observer’s belief that a future event will occur or that a particular proposition is true. Bayesianism’s advantages over frequentist probability are that it is applicable to singular events, its probability estimates can be updated based on acquisition of new information, and it can effortlessly include frequentist results. But perhaps most important, much of the weirdness associated with quantum theory—the idea that an atom can be in two places at once, or that signals can travel faster than the speed of light, or that Schrödinger’s cat can be simultaneously dead and alive—dissolves under the lens of QBism.

Using straightforward language without equations, Hans Christian von Baeyer clarifies the meaning of quantum mechanics in a commonsense way that suggests a new approach to physics in general.

In 1953, reflecting on early ventures in quantum theory, J. Robert Oppenheimer spoke of terror and exaltation, of history happening in a realm so remote from common experience that it was “unlikely to be known to any poet or historian.” Yet now, anyone can Google “quantum theory” and find more than 34 million entries—from poets and historians, certainly, as well as film critics and Buddhist monks. How—and how pervasively—quantum mechanics has entered the general culture is the subject of this book, an engaging, eclectic, and thought-provoking look at the curious, boundlessly fertile intersection of scientific thought and everyday life.

Including recollections of encounters with the theory and the people responsible for it, Jeremy Bernstein’s account ranges from the cross-pollination of quantum mechanics with Marxist ideology and Christian and Buddhist mysticism to its influence on theater, film, and fiction. Along the way, Bernstein focuses on those—such as Niels Bohr, the Dalai Lama, W. H. Auden, and Tom Stoppard—who have made quantum physics; who have argued over it, pondered it, or taken literary inspiration from it, and who have misunderstood, misconstrued, or misapplied it. One person in particular supplies a narrative thread: John Bell, a notable yet underappreciated physicist who did groundbreaking research in quantum physics. In Bell’s story, Bernstein provides a uniquely readable account of what physicists call the “measurement problem.”

Quantum Leaps is a lively, erudite book on a subject that Bernstein has lived with for most of its history. His experience and deep understanding are apparent on every page.

A series of engaging essays that explore iconic moments of discovery and debate in physicists’ ongoing quest to understand the quantum world.

The ideas at the root of quantum theory remain stubbornly, famously bizarre: a solid world reduced to puffs of probability; particles that tunnel through walls; cats suspended in zombielike states, neither alive nor dead; and twinned particles that share entangled fates. For more than a century, physicists have grappled with these conceptual uncertainties while enmeshed in the larger uncertainties of the social and political worlds around them, a time pocked by the rise of fascism, cataclysmic world wars, and a new nuclear age.
 
In Quantum Legacies, David Kaiser introduces readers to iconic episodes in physicists’ still-unfolding quest to understand space, time, and matter at their most fundamental. In a series of vibrant essays, Kaiser takes us inside moments of discovery and debate among the great minds of the era—Albert Einstein, Erwin Schrödinger, Stephen Hawking, and many more who have indelibly shaped our understanding of nature—as they have tried to make sense of a messy world.
 
Ranging across space and time, the episodes span the heady 1920s, the dark days of the 1930s, the turbulence of the Cold War, and the peculiar political realities that followed. In those eras as in our own, researchers’ ambition has often been to transcend the vagaries of here and now, to contribute lasting insights into how the world works that might reach beyond a given researcher’s limited view. In Quantum Legacies, Kaiser unveils the difficult and unsteady work required to forge some shared understanding between individuals and across generations, and in doing so, he illuminates the deep ties between scientific exploration and the human condition.

The more science tells us about the world, the stranger it looks. Ever since physics first penetrated the atom, early in this century, what it found there has stood as a radical and unanswered challenge to many of our most cherished conceptions of nature. It has literally been called into question since then whether or not there are always objective matters of fact about the whereabouts of subatomic particles, or about the locations of tables and chairs, or even about the very contents of our thoughts. A new kind of uncertainty has become a principle of science.

This book is an original and provocative investigation of that challenge, as well as a novel attempt at writing about science in a style that is simultaneously elementary and deep. It is a lucid and self-contained introduction to the foundations of quantum mechanics, accessible to anyone with a high school mathematics education, and at the same time a rigorous discussion of the most important recent advances in our understanding of that subject, some of which are due to the author himself.

As Kenneth W. Ford shows us in The Quantum World, the laws governing the very small and the very swift defy common sense and stretch our minds to the limit. Drawing on a deep familiarity with the discoveries of the twentieth century, Ford gives an appealing account of quantum physics that will help the serious reader make sense of a science that, for all its successes, remains mysterious. In order to make the book even more suitable for classroom use, the author, assisted by Diane Goldstein, has included a new section of Quantum Questions at the back of the book. A separate answer manual to these 300+ questions is available; visit The Quantum World website for ordering information.

There is also a cloth edition of this book, which does not include the "Quantum Questions" included in this paperback edition.

R. I. G. Hughes offers the first detailed and accessible analysis of the Hilbert-space models used in quantum theory and explains why they are so successful. He goes on to show how the very suitability of Hilbert spaces for modeling the quantum world gives rise to deep problems of interpretation, and makes suggestions about how they can be overcome.
