Quantum Physics: What Everyone Needs to Know®

Around 1900, physicists started to discover particles like electrons, protons, and neutrons, and with these discoveries believed they could predict the internal behavior of the atom. However, once their predictions were compared to the results of experiments in the real world, it became clear that the principles of classical physics and mechanics were far from capable of explaining phenomena on the atomic scale. With this realization came the advent of quantum physics, one of the most important intellectual movements in human history. Today, quantum physics is everywhere: it explains how our computers work, how lasers transmit information across the Internet, and allows scientists to predict accurately the behavior of nearly every particle in nature. Its application continues to be fundamental in the investigation of the most expansive questions related to our world and the universe.However, while the field and principles of quantum physics are known to have nearly limitless applications, the fundamental reasons why this is the case are far less understood. In Quantum Physics: What Everyone Needs to Know, quantum physicist Michael G. Raymer distills the basic principles of such an abstract field, and addresses the many ways quantum physics is a key factor in today's science and beyond. The book tackles questions as broad as the meaning of quantum entanglement and as specific and timely as why governments worldwide are spending billions of dollars developing quantum technology research. Raymer's list of topics is diverse, and showcases the sheer range of questions and ideas in which quantum physics is involved. From applications like data encryption and quantum computing to principles and concepts like "quantum nonlocality" and Heisenberg's uncertainty principle, Quantum Physics: What Everyone Needs to Know is a wide-reaching introduction to a nearly ubiquitous scientific topic.

Quantum Mechanics: The Theoretical Minimum

From the bestselling author of The Theoretical Minimum, a DIY introduction to the math and science of quantum mechanics.First he taught you classical mechanics. Now, physicist Leonard Susskind has teamed up with data engineer Art Friedman to present the theory and associated mathematics of the strange world of quantum mechanics.In this follow-up to the New York Times best-selling The Theoretical Minimum, Susskind and Friedman provide a lively introduction to this famously difficult field, which attempts to understand the behavior of sub-atomic objects through mathematical abstractions. Unlike other popularizations that shy away from quantum mechanics' weirdness, Quantum Mechanics embraces the utter strangeness of quantum logic. The authors offer crystal-clear explanations of the principles of quantum states, uncertainty and time dependence, entanglement, and particle and wave states, among other topics, and each chapter includes exercises to ensure mastery of each area. Like The Theoretical Minimum, this volume runs parallel to Susskind's eponymous Stanford University-hosted continuing education course.An approachable yet rigorous introduction to a famously difficult topic, Quantum Mechanics provides a tool kit for amateur scientists to learn physics at their own pace.

Reality Is Not What It Seems: The Journey to Quantum Gravity

“The man who makes physics sexy . . . the scientist they’re calling the next Stephen Hawking.” —The Times MagazineFrom the New York Times–bestselling author of Seven Brief Lessons on Physics and The Order of Time, a closer look at the mind-bending nature of the universe.What are the elementary ingredients of the world? Do time and space exist? And what exactly is reality? Theoretical physicist Carlo Rovelli has spent his life exploring these questions. He tells us how our understanding of reality has changed over the centuries and how physicists think about the structure of the universe today. In elegant and accessible prose, Rovelli takes us on a wondrous journey from Democritus to Albert Einstein, from Michael Faraday to gravitational waves, and from classical physics to his own work in quantum gravity. As he shows us how the idea of reality has evolved over time, Rovelli offers deeper explanations of the theories he introduced so concisely in Seven Brief Lessons on Physics. This book culminates in a lucid overview of quantum gravity, the field of research that explores the quantum nature of space and time, seeking to unify quantum mechanics and general relativity. Rovelli invites us to imagine a marvelous world where space breaks up into tiny grains, time disappears at the smallest scales, and black holes are waiting to explode—a vast universe still largely undiscovered.

The Elegant Universe: Superstrings, Hidden Dimensions, and the Quest for the Ultimate Theory

A new edition of the New York Times bestseller—now a three-part Nova special: a fascinating and thought-provoking journey through the mysteries of space, time, and matter.Now with a new preface (not in any other edition) that will review the enormous public reception of the relatively obscure string theory—made possible by this book and an increased number of adherents amongst physicists—The Elegant Universe "sets a standard that will be hard to beat" (New York Times Book Review). Brian Greene, one of the world's leading string theorists, peels away the layers of mystery surrounding string theory to reveal a universe that consists of eleven dimensions, where the fabric of space tears and repairs itself, and all matter—from the smallest quarks to the most gargantuan supernovas—is generated by the vibrations of microscopically tiny loops of energy.Today physicists and mathematicians throughout the world are feverishly working on one of the most ambitious theories ever proposed: superstring theory. String theory, as it is often called, is the key to the Unified Field Theory that eluded Einstein for more than thirty years. Finally, the century-old antagonism between the large and the small-General Relativity and Quantum Theory-is resolved. String theory proclaims that all of the wondrous happenings in the universe, from the frantic dancing of subatomic quarks to the majestic swirling of heavenly galaxies, are reflections of one grand physical principle and manifestations of one single entity: microscopically tiny vibrating loops of energy, a billionth of a billionth the size of an atom. In this brilliantly articulated and refreshingly clear book, Greene relates the scientific story and the human struggle behind twentieth-century physics' search for a theory of everything.Through the masterful use of metaphor and analogy, The Elegant Universe makes some of the most sophisticated concepts ever contemplated viscerally accessible and thoroughly entertaining, bringing us closer than ever to understanding how the universe works.

Quantum Physics: an overview of a weird world: A primer on the conceptual foundations of quantum physics for all

A primer on the conceptual foundations of quantum physics for all. A course on the conceptual foundations of quantum physics on topics that you won't find elsewhere, explained at introductory level. It is designed to be a comprehensive A-Z guide that will save you a ton of time in searching elsewhere trying to piece all the different information together. Not just a ‘quantum physics for dummies‘ but a high level and professional account which remains nevertheless accessible to all. Considering how the media (sometimes also physicists) present quantum theory focusing only on highly dubious ideas and speculations backed by no evidence or, worse, promote pseudo-scientific hypes that fall regularly into and out of fashion, this book fills a void: that of a serious introduction to the conceptual foundations of quantum physics, as it really is, and avoiding vulgarized oversimplifications.  This book is for all those who always wanted to understand the principles of quantum physics, even if they are not physicists. For those who always have been attracted by the fascinating and weird quantum world, but found only advanced level university courses, or superficial popular science or pseudo-scientific theories. For those who searched for a course that explains the basics of the conceptual foundations of quantum mechanics, but that does not presuppose a technical preparation, and yet furnishes the most rigorous and advanced account as far an (almost) non-mathematical exposition allows for.Since in schools, colleges and universities, quantum physics is taught with a dry and mostly technical approach which furnishes only a superficial insight on its foundations, this book is recommended also to school, undergraduate, graduate students and physicists who would like to look beyond.From the index, these are roughly the topics covered.Quantum prehistory: particles, waves, and light The question of the nature of lightWaves and InterferenceA brief mathematical interludeYoung’s double slit experimentThe birth and foundations of quantum physics The blackbody radiationMore evidence for photons and discrete energy levelsWaves strike back: Bragg diffraction and the De Broglie hypothesisThe wave-particle dualityHeisenberg’s uncertainty principleThe wavefunction and the measurement problemSchrödinger's equation and atomic physicsThe quantum world of spinning particles Angular momentum in classical mechanicsSpin, the Stern-Gerlach experiment and the commutation relationIs information fundamental?The spinning world of spinorsThe photon’s polarization and spinQuantum ubiquity and randomness The quantum superposition principleSchrödinger’s cat paradoxThe time-energy uncertainty relationThe quantum tunnel effectZero-point energy and virtual particlesThe Bohr-Einstein debateQuantum entanglement Quantum scattering and indistinguishabilityQuantum entanglement of spin-half particlesThe EPR paradox (original version)The EPR paradox (modern version)Faster than light transmissions?Bell’s legacy Is the Moon there when nobody looks?Photon entanglementCorrelation coefficientsBell’s inequalityBell’s theoremDigging deeper into the quantum realmBosons, fermions and Pauli’s exclusion principle or: the stability of matterPhase matters: the Aharonov-Bohm effectPath integrals and Feynman diagramsThe quantum Zeno effectQuantum ontology rebornThe ‘which-way’ experimentsThe ‘quantum erasure’ experimentsThe ‘delayed choice’ experimentsThe Scully-Englert-Walther experiment and the complementary principleQuantum teleportation

What Is Real?: The Unfinished Quest for the Meaning of Quantum Physics

The untold story of the heretical thinkers who dared to question the nature of our quantum universeEvery physicist agrees quantum mechanics is among humanity's finest scientific achievements. But ask what it means, and the result will be a brawl. For a century, most physicists have followed Niels Bohr's Copenhagen interpretation and dismissed questions about the reality underlying quantum physics as meaningless. A mishmash of solipsism and poor reasoning, Copenhagen endured, as Bohr's students vigorously protected his legacy, and the physics community favored practical experiments over philosophical arguments. As a result, questioning the status quo long meant professional ruin. And yet, from the 1920s to today, physicists like John Bell, David Bohm, and Hugh Everett persisted in seeking the true meaning of quantum mechanics. What Is Real? is the gripping story of this battle of ideas and the courageous scientists who dared to stand up for truth.

Quantum Enigma: Physics Encounters Consciousness

In trying to understand the atom, physicists built quantum mechanics, the most successful theory in science and the basis of one-third of our economy. They found, to their embarrassment, that with their theory, physics encounters consciousness. Authors Bruce Rosenblum and Fred Kuttner explain all this in non-technical terms with help from some fanciful stories and anecdotes about the theory's developers. They present the quantum mystery honestly, emphasizing what is and what is not speculation. Quantum Enigma's description of the experimental quantum facts, and the quantum theory explaining them, is undisputed. Interpreting what it all means, however, is heatedly controversial. But every interpretation of quantum physics involves consciousness. Rosenblum and Kuttner therefore turn to exploring consciousness itself--and encounter quantum mechanics. Free will and anthropic principles become crucial issues, and the connection of consciousness with the cosmos suggested by some leading quantum cosmologists is mind-blowing. Readers are brought to a boundary where the particular expertise of physicists is no longer the only sure guide. They will find, instead, the facts and hints provided by quantum mechanics and the ability to speculate for themselves.In the few decades since the Bell's theorem experiments established the existence of entanglement (Einstein's "spooky action"), interest in the foundations, and the mysteries, of quantum mechanics has accelerated. In recent years, physicists, philosophers, computer engineers, and even biologists have expanded our realization of the significance of quantum phenomena. This second edition includes such advances. The authors have also drawn on many responses from readers and instructors to improve the clarity of the book's explanations.
