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 of the courageous scientists who dared to stand up for truth.

    Thomas Young devised it in the early 1800s to show that light behaves like a wave, and in doing so opposed Isaac Newton. Nearly a century later, Albert Einstein showed that light comes in quanta, or particles, and the experiment became key to a fierce debate between Einstein and Niels Bohr over the nature of reality. Richard Feynman held that the double slit embodies the central mystery of the quantum world. Decade after decade, hypothesis after hypothesis, scientists have returned to this ingenious experiment to help them answer deeper and deeper questions about the fabric of the universe.How can a single particle behave both like a particle and a wave? Does a particle exist before we look at it, or does the very act of looking create reality? Are there hidden aspects to reality missing from the orthodox view of quantum physics? Is there a place where the quantum world ends and the familiar classical world of our daily lives begins, and if so, can we find it? And if there's no such place, then does the universe split into two each time a particle goes through the double slit?With his extraordinarily gifted eloquence, Anil Ananthaswamy travels around the world and through history, down to the smallest scales of physical reality we have yet fathomed. Through Two Doors at Once is the most fantastic voyage you can take.

    But when Feynman said he didn’t understand quantum mechanics, he didn’t mean that he couldn’t do it – he meant that’s all he could do. He didn’t understand what the maths was saying: what quantum mechanics tells us about reality.Over the past decade or so, the enigma of quantum mechanics has come into sharper focus. We now realise that quantum mechanics is less about particles and waves, uncertainty and fuzziness, than a theory about information: about what can be known and how.This is more disturbing than our bad habit of describing the quantum world as ‘things behaving weirdly’ suggests. It calls into question the meanings and limits of space and time, cause and effect, and knowledge itself.The quantum world isn’t a different world: it is our world, and if anything deserves to be called ‘weird’, it’s us. This exhilarating book is about what quantum maths really means – and what it doesn’t mean.

    While maintaining that “the letters record the daily life of an ordinary scientist doing ordinary work,” Dyson nonetheless has worked with many of the twentieth century’s most renowned physicists, mathematicians, and intellectuals, so that Maker of Patterns presents not only his personal story but chronicles through firsthand accounts an exciting era of twentieth-century science.Though begun in the dark year of 1941 when Hitler’s armies had already conquered much of Europe, Dyson’s letters to his parents, written at Trinity College, Cambridge, often burst with the curiosity of a precocious seventeen-year-old. Pursuing mathematics and physics with a cast of legendary professors, Dyson thrived in Cambridge’s intellectual ferment, working on, for example, the theory of partitions or reading about Kurt Gödel’s hypotheses, while still finding time for billiards and mountain climbing. After graduating and serving with the Royal Air Force’s Bomber Command operational research section, whose job it was “to demolish German cities and kill as many German civilians as possible,” Dyson visited a war-torn Germany, hoping through his experience to create a “tolerably peaceful world.”Juxtaposing descriptions of scientific breakthroughs with concerns for mankind’s future, Dyson’s postwar letters reflect the quandaries faced by an entire scientific generation that was dealing with the aftereffects of nuclear detonations and concentration camp killings. Arriving in America in 1947 to study with Cornell’s Hans Bethe, Dyson continued to send weekly missives to England that were never technical but written with grace and candor, creating a portrait of a generation that was eager, as Einstein once stated, to solve “deep mysteries that Nature intend[ed] to keep for herself.”We meet, among others, scientists like Richard Feynman, who took Dyson across country on Route 66, Robert Oppenheimer, Eugene Wigner, Niels Bohr, James Watson, and a young Stephen Hawking; and we encounter intellectuals and leaders, among them Reinhold Niebuhr, George Kennan, Arthur C. Clarke, as well as Martin Luther King, Jr.The “patterns of comparable beauty in the dance of electrons jumping around atoms” invariably replicate themselves in this autobiography told through letters, one that combines accounts of wanton arms development with the not-inconsiderable demands of raising six children. As we once again attempt to guide society toward a more hopeful future, these letters, with their reenactment of what, at first, seems like a distant past, reveal invaluable truths about human nature.

    Can a computer think? Why is your consciousness like Bitcoin? Will there be an artificial intelligence apocalypse?

    Every massive star leaves behind a black hole when it dies, and every galaxy harbors a supermassive black hole at its center. Frighteningly enigmatic, these dark giants continue to astound even the scientists who spend their careers studying them. Which came first, the galaxy or its central black hole? What happens if you travel into one—instant death or something weirder? And, perhaps most important, how can we ever know anything for sure about black holes when they destroy information by their very nature?In Einstein’s Monsters, distinguished astronomer Chris Impey takes readers on an exploration of these and other questions at the cutting edge of astrophysics, as well as the history of black holes’ role in theoretical physics—from confirming Einstein’s equations for general relativity to testing string theory. He blends this history with a poignant account of the phenomena scientists have witnessed while observing black holes: stars swarming like bees around the center of our galaxy; black holes performing gravitational waltzes with visible stars; the cymbal clash of two black holes colliding, releasing ripples in space-time.Clear, compelling, and profound, Einstein’s Monsters reveals how our comprehension of black holes is intrinsically linked to how we make sense of the universe and our place within it. From the small questions to the big ones—from the tiniest particles to the nature of space-time itself—black holes might be the key to a deeper understanding of the cosmos.

    Bringing together the best and most interesting science stories appearing in Quanta Magazine over the past five years, Alice and Bob Meet the Wall of Fire reports on some of the greatest scientific minds as they test the limits of human knowledge. Quanta, under editor-in-chief Thomas Lin, is the only popular publication that offers in-depth coverage of today's challenging, speculative, cutting-edge science. It communicates science by taking it seriously, wrestling with difficult concepts and clearly explaining them in a way that speaks to our innate curiosity about our world and ourselves.In the title story, Alice and Bob--beloved characters of various thought experiments in physics--grapple with gravitational forces, possible spaghettification, and a massive wall of fire as Alice jumps into a black hole. Another story considers whether the universe is impossible, in light of experimental results at the Large Hadron Collider. We learn about quantum reality and the mystery of quantum entanglement; explore the source of time's arrow; and witness a eureka moment when a quantum physicist exclaims: "Finally, we can understand why a cup of coffee equilibrates in a room." We reflect on humans' enormous skulls and the Brain Boom; consider the evolutionary benefits of loneliness; peel back the layers of the newest artificial-intelligence algorithms; follow the "battle for the heart and soul of physics"; and mourn the disappearance of the "diphoton bump," revealed to be a statistical fluctuation rather than a revolutionary new particle. These stories from Quanta give us a front-row seat to scientific discovery.ContributorsPhilip Ball, K. C.

    Whether pondering black holes or predicting discoveries at CERN, physicists believe the best theories are beautiful, natural, and elegant, and this standard separates popular theories from disposable ones. This is why, Sabine Hossenfelder argues, we have not seen a major breakthrough in the foundations of physics for more than four decades. The belief in beauty has become so dogmatic that it now conflicts with scientific objectivity: observation has been unable to confirm mindboggling theories, like supersymmetry or grand unification, invented by physicists based on aesthetic criteria. Worse, these "too good to not be true" theories are actually untestable and they have left the field in a cul-de-sac. To escape, physicists must rethink their methods. Only by embracing reality as it is can science discover the truth.

    But gravitational waves – ripples in the fabric of space and time – are unrelenting, passing through barriers that stop light dead.At the two 4-kilometre long LIGO observatories in the US, scientists developed incredibly sensitive detectors, capable of spotting a movement 100 times smaller than the nucleus of an atom. In 2015 they spotted the ripples produced by two black holes spiralling into each other, setting spacetime quivering.This was the first time black holes had ever been directly detected – and it promises far more for the future of astronomy. Brian Clegg presents a compelling story of human technical endeavour and a new, powerful path to understand the workings of the universe.Brian Clegg’s most recent books are The Reality Frame (Icon, 2017), What Colour is the Sun?

    That strategy, the result of nearly 2 years of effort by the survey committee, which worked with more than 100 scientists and engineers on eight supporting study panels, is presented in the 2013 publication, Solar and Space Physics: A Science for a Technological Society. This booklet, designed to be accessible to a broader audience of policymakers and the interested public, summarizes the content of that report.

    That's 102 Lego(R) bricks for every person in the world. That's nothing however to the estimated seven billion billion billion atoms that make up each of us, let alone the between ten quadrillion vigintillion and one-hundred thousand quadrillion vigintillion atoms in the known observable universe.Thankfully, understanding atomic and subatomic physics need not be infathomable. Lego(R) bricks are a great way to visualize the blueprint of the Universe, right down to its smallest elements.Particle Physics Brick by Brick explains how and with what the universe came to be. It introduces the Standard Model of Physics, the "rule book" of physics which has been proven correct again and again since its mid-20 century development. Today, it is the gaps in the model that keep physicists busy.In concise chapters, the book assigns to each atomic element a colored Lego(R) brick, such as neutrons, leptons, and quarks. By assembling actual or imaginary bricks and observing their relationships and interactions, particle physics becomes clear. The book opens with the Standard Model of Physics, the physicists and the discoveries made over history, and directions on how to use the book.The chapters that follow are:Building Blocks and Construction Rules Building a Universe Electromagnetism and QED (Quantum ElectroDynamics) The Strong Force and QCD (Quantum ChromoDynamics) The Weak Force and Breaking Symmetries Broken Symmetry and Mass Problems with Ghosts Violated Symmetry The Future. Particle Physics Brick by Brick is a succinct introduction for anyone that wants to gain a basic understanding of the atomic world, its elements and how they interact. By using tangible substitutes -- bricks -- it brings the unseen atomic world into the realm of the visual.

    In this book, Jack Challoner places the atom at center stage. The Atom investigates the quest to identify the smallest, most fundamental constituents of matter--and how that quest helps us to understand what everything is made of and how it all works. Challoner covers a wide range of topics--including the development of scientific thinking about atoms and the basic structure of atoms; how atomic interactions account for the familiar properties of everyday materials; the power of the atomic nucleus; and what the mysterious quantum realm of subatomic particles can tell us about the very nature of reality.Illustrated in color throughout, The Atom offers clear answers to questions we have all pondered, as well as some we have never even dreamed of. It describes the amazing discoveries scientists have made about the fundamental building blocks of matter--from quarks to nuclear fission to the "God particle"--and explains them accessibly and concisely. The Atom is the engaging and straightforward introduction to the topic that we didn't get in school.

    The concepts involved may be sophisticated, but Giles Sparrow’s effortless prose style renders them understandable, allowing readers to come to grips with the overarching debates at the cutting edge of cosmology today. Illustrations, diagrams, and astronomical visualizations demonstrate and clarify the various astonishing implications of a universe of infinite space.This entry in the “Big Idea” series explores four key topics: “Mapping Space,” featuring the evidence that favors the expanding and infinite universe theory; “The Expanding Universe,” which examines the rate at which the cosmos is expanding; “The Omega Factor,” which explores the possibilities for different types of hypothetically infinite universes; and “The Shape of the Multiverse,” which analyzes the effect of each possible shape on the likely future of the universe.Well-informed and lucid, What Shape Is Space? is an in-depth and approachable exploration of the ideas and possibilities born from this seemingly simple question.

    The author, a researcher in mathematical physics, responds to dozens of questions posed by inquiring minds from all over the world, ranging from the everyday to the profound.Rather than unnecessarily complex explanations mired in mysterious terminology and symbols, the reader is presented with the reasoning, experiments, and mathematics in a casual, conversational, and often comical style. Neither over-simplified nor over-technical, the lucid and entertaining writing will guide the reader from each innocent question to a better understanding of the weird and beautiful universe around us. Advance praise for Do Colors Exist?: "Every high school science teacher should have a copy of this book. The individual articles offer enrichment to those students who wish to go beyond a typical 'dry curriculum'. The articles are very fun. I probably laughed out loud every 2-3 minutes. This is not easy to do. In fact, my children are interested in the book because they heard me laughing so much."- Ken Ono, Emory University

    But any theory that doesn't is a waste of time. Desmond articulates a vision that just might be wild enough to take us home.” Brian Thomas Swimme, Author of Journey of the Universe “Psyche and Singularity is one of the most profoundly significant books I’ve had the pleasure to read. Tracing striking parallels between string theory and Jungian thought, Desmond provides the most compelling explanation for how synchronicities work that I’ve encountered.” Grant Maxwell, Author of The Dynamics of Transformation: Tracing an Emerging World View “The discussion may sound like insane science fiction, but Desmond offers a refreshingly accurate picture, a synthesis of psyche and quantum physics that becomes the key to unlock a map of consciousness and synchronicity backed by the central ideas of Pauli, Susskind, and Jung.” Shelli Joye, Author of Tuning the Mind: Holonomic Brain Theory and the Implicate Order According to Stanford physicist Leonard Susskind, our three-dimensional universe is essentially a holographic “movie,” an illusion projected by one-dimensional threads of energy from the spherical horizon of the cosmos, where the past, present, and future are eternally superimposed. Psyche and Singularity shows how Susskind’s string theory of holographic information conservation corroborates some of psychologist Carl Jung’s most profound ideas. Timothy Desmond suggests that Susskind’s inside-out black hole model of the universe forms a geometrically perfect mandala: a central singularity encompassed by a two-dimensional sphere which serves as a universal memory bank. In precise fulfillment of Jung’s theory about the unifying quality of the mandala image as the “archetype of wholeness,” Susskind’s model of the universe reconciles the notoriously incommensurable paradigms of general relativity and quantum mechanics, providing a mathematically plausible explanation for Jung’s near-death experience of his past, present, and future life simultaneously at the cosmic horizon. Susskind’s theory also provides a plausible cosmological model to explain Jung’s theory of synchronicity— meaningful coincidences may be tied together by strings at the cosmic horizon, from which they radiate inward.

    You cannot identify the irritation, but it feels as if there should be something more. Because of this, you begin to look for answers outside of the normal channels and your awakening commences. The messages for awakening are as diverse as their sources because they are designed to reach different levels of consciousness—yet the truth is always the truth, though the form it takes may vary.Expansion for Ascending Consciousness is a cooperative effort to provide a basis for understanding consciousness and the energy construct we exist within. The intent is to remove the mysticism surrounding consciousness and embodied experience. While complex and miraculous in its design, consciousness is scientifically explainable and the foundation upon which the universe has been created. As an ascending collective, you have reached a time in your development where mysticism has outlived its usefulness.Truth comes in many forms, and thus the information you gravitate to at any given moment is dependent upon what resonates with your current level of awakening. At a point in this process you will look back upon the information you have accumulated and see that each one was a step that incrementally raised your awareness. Expansion for Ascending Consciousness contains the next step along this path of ascension.

    Lagrangian and Hamiltonian dynamics is the continuation of Newton's classical physics into new formalisms, each highlighting novel aspects of mechanics thatgradually build in complexity to form the basis for almost all of theoretical physics. Lagrangian and Hamiltonian dynamics also acts as a gateway to more abstract concepts routed in differential geometry and field theories and can be used to introduce these subject areas to newcomers.Journeying in a self-contained manner from the very basics, through the fundamentals and onwards to the cutting edge of the subject, along the way the reader is supported by all the necessary background mathematics, fully worked examples, thoughtful and vibrant illustrations as well as an informalnarrative and numerous fresh, modern and inter-disciplinary applications.The book contains some unusual topics for a classical mechanics textbook. Most notable examples include the 'classical wavefunction', Koopman-von Neumann theory, classical density functional theories, the 'vakonomic' variational principle for non-holonomic constraints, the Gibbs-Appell equations, classical path integrals, Nambu brackets and the full framing of mechanics in the language of differential geometry.

    Starting from an experimental perspective, it provides a unified view of these fields that reflects the very rapid advances being made. This new edition has a number of improvements and has been updated to describe the recent discovery of gravitational waves and astrophysical neutrinos, which started the new era of multimessenger astrophysics; it also includes new results on the Higgs particle. Astroparticle and particle physics share a common problem: we still don't have a description of the main ingredients of the Universe from the point of view of its energy budget. Addressing these fascinating issues, and offering a balanced introduction to particle and astroparticle physics that requires only a basic understanding of quantum and classical physics, this book is a valuable resource, particularly for advanced undergraduate students and for those embarking on graduate courses. It includes exercises that offer readers practical insights can be used equally well as a self-study book, a reference and a textbook.

    This fun and contrarian novel is full of fireworks which will make you think about the strange, the unusual, and the unexpected consequences of our quest for civilization and knowledge. The author spent 20 years studying physics before quitting her academic job in exasperation.

    I used to know it all:who was bound for heaven and who would be in hell,how the contradictions in the Bible all fit together when read with guidance from the Spirit and in keeping with our church’s exact teaching.How to fix government, end war, and balance capitalism with community,what was true and what was false,how the world made sense and why it was fair.Then my sure answers became unacceptable.Now I know mostly little things:the love of family,the importance of children,the need to live in the circle of a tribe,the freedom of unknowing,the joy of being in trees and on rocks under birds in flight,the comfort of not being responsible for all things and all people,the power each moment to choose behavior that will add to the heaven or hell experienced in the present by real people,the beauty of the dance of atoms and stars bracketing the grand diversity and mysteries of life.I know One Universe which creates, knows, sustains, and is.One is enough.

    While Volume 1 is devoted to the theory and experiments, Volume 2 discusses what can be learned from gravitational waves in astrophysics and in cosmology, bysystematizing a large body of theoretical developments that have taken place over the last decades. The second volume also includes a detailed discussion of the first direct detections of gravitational waves. In the author's typical style, the theoretical results are generally derived afresh, clarifying or streamlining the existing derivations whenever possible, and providing a coherent and consistent picture of the field.The first volume of Gravitational Waves, which appeared in 2007, has established itself as the standard reference in the field. The scientific community has eagerly awaited this second volume. The recent direct detection of gravitational waves makes the topics in this book particularly timely.

    In standard quantum mechanics, it is postulated that when the wave function of a quantum system is measured, it no longer follows the Schrodinger equation, but instantaneously and randomly collapses to one of the wave functions that correspond to definite measurement results. However, why and how a definite measurement result appears is unknown. A promising solution to this problem are collapse theories in which the collapse of the wave function is spontaneous and dynamical. Chapters written by distinguished physicists and philosophers of physics discuss the origin and implications of wave-function collapse, the controversies around collapse models and their ontologies, and new arguments for the reality of wave function collapse. This is an invaluable resource for students and researchers interested in the philosophy of physics and foundations of quantum mechanics.

    It emphasizes applications and simulation utilizing Python.The hands-on approach of Dynamical Systems with Applications using Python has minimal prerequisites, only requiring familiarity with ordinary differential equations.

This empowering code was missing from Dan Brown's famous novel and movie, The Da Vinci Code. The fact is these truths are so freeing that some people don't want you to know or use them. In LOVE The Real Da Vinci CODE, Harvard-trained researcher, Dr. Leonard Horowitz, makes an unprecedented contribution. Honored by the World Organization for Natural Medicine as a World Leading Intellectual, the award-winning author of sixteen books has now cracked the real Da Vinci code. Exercising this knowledge can produce prosperity and a healthier destiny for users of this knowledge and wisdom. LOVE The Real Da Vinci CODE reveals the sacred music, creative mathematics, and Divine language empowering the Laws of physics, chemistry, spirituality, and more. Dr. Horowitz spent more than a quarter century researching healthy human development. His previous books, Walk on Water, DNA: Pirates of the Sacred Spiral, and Healing Codes for the Biological Apocalypse, featured the musical-mathematics of intelligent design underlying evolution of the species. His research into LOVE The Real Da Vinci CODE was prompted by his discovery of a Perfect Circle of Sound hidden within Da Vinci's most famous drawing, The Vitruvian Man. The Vitruvian Man is Da Vinci's artistic rendering of your perfect self in universal balance and Divine communion. This knowledge bridges all religious and cultural divides.

    It helps students plot a careful path to understanding the core ideas and basics of differential geometry, as applied to general relativity, without overwhelming them. While the guide doesn't shy away from necessary technicalities, it emphasises the essential simplicity of the main physical arguments. Presuming a familiarity with special relativity (with a brief account in an appendix), it describes how general covariance and the equivalence principle motivate Einstein's theory of gravitation. It then introduces differential geometry and the covariant derivative as the mathematical technology which allows us to understand Einstein's equations of general relativity. The book is supported by numerous worked exampled and problems, and important applications of general relativity are described in an appendix.

    In this collection of twenty-six intriguing problems, he explores how mathematical physicists think. Always entertaining, the problems range from ancient catapult conundrums to the puzzling physics of a very peculiar kind of glass called NASTYGLASS--and from dodging trucks to why raindrops fall slower than the rate of gravity. The questions raised may seem impossible to answer at first and may require an unexpected twist in reasoning, but sometimes their solutions are surprisingly simple. Nahin's goal, however, is always to guide readers--who will need only to have studied advanced high school math and physics--in expanding their mathematical thinking to make sense of the curiosities of the physical world.The problems are in the first part of the book and the solutions are in the second, so that readers may challenge themselves to solve the questions on their own before looking at the explanations. The problems show how mathematics--including algebra, trigonometry, geometry, and calculus--can be united with physical laws to solve both real and theoretical problems. Historical anecdotes woven throughout the book bring alive the circumstances and people involved in some amazing discoveries and achievements.More than a puzzle book, this work will immerse you in the delights of scientific history while honing your math skills.
