Download or read book Not Even Wrong written by Peter Woit and published by Random House. This book was released on 2011-08-31 with total page 306 pages. Available in PDF, EPUB and Kindle. Book excerpt: Not Even Wrong is a fascinating exploration of our attempts to come to grips with perhaps the most intellectually demanding puzzle of all: how does the universe work at its most fundamnetal level? The book begins with an historical survey of the experimental and theoretical developments that led to the creation of the phenomenally successful 'Standard Model' of particle physics around 1975. Despite its successes, the Standard Model does not answer all the key questions and physicists continuing search for answers led to the development of superstring theory. However, after twenty years, superstring theory has failed to advance beyond the Standard Model. The absence of experimental evidence is at the core of this controversial situation which means that it is impossible to prove that superstring theory is either right or wrong. To date, only the arguments of the theory's advocates have received much publicity. Not Even Wrong provides readers with another side of the story.

Download or read book Warped Passages written by Lisa Randall and published by Harper Collins. This book was released on 2009-10-21 with total page 782 pages. Available in PDF, EPUB and Kindle. Book excerpt: The universe has many secrets. It may hide additional dimensions of space other than the familier three we recognize. There might even be another universe adjacent to ours, invisible and unattainable . . . for now. Warped Passages is a brilliantly readable and altogether exhilarating journey that tracks the arc of discovery from early twentieth-century physics to the razor's edge of modern scientific theory. One of the world's leading theoretical physicists, Lisa Randall provides astonishing scientific possibilities that, until recently, were restricted to the realm of science fiction. Unraveling the twisted threads of the most current debates on relativity, quantum mechanics, and gravity, she explores some of the most fundamental questions posed by Nature—taking us into the warped, hidden dimensions underpinning the universe we live in, demystifying the science of the myriad worlds that may exist just beyond our own.

Download or read book Quantum Theory Groups and Representations written by Peter Woit and published by Springer. This book was released on 2017-11-01 with total page 668 pages. Available in PDF, EPUB and Kindle. Book excerpt: This text systematically presents the basics of quantum mechanics, emphasizing the role of Lie groups, Lie algebras, and their unitary representations. The mathematical structure of the subject is brought to the fore, intentionally avoiding significant overlap with material from standard physics courses in quantum mechanics and quantum field theory. The level of presentation is attractive to mathematics students looking to learn about both quantum mechanics and representation theory, while also appealing to physics students who would like to know more about the mathematics underlying the subject. This text showcases the numerous differences between typical mathematical and physical treatments of the subject. The latter portions of the book focus on central mathematical objects that occur in the Standard Model of particle physics, underlining the deep and intimate connections between mathematics and the physical world. While an elementary physics course of some kind would be helpful to the reader, no specific background in physics is assumed, making this book accessible to students with a grounding in multivariable calculus and linear algebra. Many exercises are provided to develop the reader's understanding of and facility in quantum-theoretical concepts and calculations.

Download or read book The Strangest Man written by Graham Farmelo and published by Basic Books. This book was released on 2009-08-25 with total page 560 pages. Available in PDF, EPUB and Kindle. Book excerpt: Paul Dirac was among the great scientific geniuses of the modern age. One of the discoverers of quantum mechanics, the most revolutionary theory of the past century, his contributions had a unique insight, eloquence, clarity, and mathematical power. His prediction of antimatter was one of the greatest triumphs in the history of physics. One of Einstein’s most admired colleagues, Dirac was in 1933 the youngest theoretician ever to win the Nobel Prize in physics. Dirac’s personality is legendary. He was an extraordinarily reserved loner, relentlessly literal-minded and appeared to have no empathy with most people. Yet he was a family man and was intensely loyal to his friends. His tastes in the arts ranged from Beethoven to Cher, from Rembrandt to Mickey Mouse. Based on previously undiscovered archives, The Strangest Man reveals the many facets of Dirac’s brilliantly original mind. A compelling human story, The Strangest Man also depicts a spectacularly exciting era in scientific history.

Download or read book Shell Beach written by Jesper Møller Grimstrup and published by Dansk Isbn-Kontor. This book was released on 2021-01-27 with total page 276 pages. Available in PDF, EPUB and Kindle. Book excerpt: Does a final theory really exist? And what does it feel like to spend your life searching for it? These are some of the questions the theoretical physicist Jesper Møller Grimstrup writes about in Shell Beach. It is a book about quantum gravity, about white-water kayaking, and about a life in science. It is about conferences and smoky offices, about the quest for a final theory, and about hitchhiking illegally through Tibet. Jesper Møller Grimstrup has been an active researcher in theoretical physics for the past 20 years and in Shell Beach, he combines his research in high energy physics with his personal adventures. It is a story that involves not only the science but also Kafka's novels, sci-fi movies, and surfing giant waves off the southern shores of Iceland. Shell Beach consists of several intertwined tracks, where hardcore meets soft-core. First, there is the science, which starts with quantum mechanics and relativity and then passes through the standard model of particle physics to end up with modern topics such as noncommutative geometry and loop quantum gravity. Second, there the philosophy, the idea of a final theory, and what we might expect to find, should our search one day come to an end. And finally, there is the personal journey, that begins with a young scientist with independent ideas, who is eventually pushed into an orbit without a job and funded by crowdsourcing. In fact, Shell Beach is the outcome of a crowdfunding campaign that Jesper Møller Grimstrup ran in 2016 - it is one of the perks to his supporters. A key theme in Shell Beach is the idea, that the theory of everything could turn out to be conceptually empty and tell us little of significance. That it will not provide us with answers to our most urgent questions such as "why are we here?" This idea, which Grimstrup's own candidate for a final theory exemplifies, is illustrated through literature and film, and is followed by the question: "what will it do to us if we find that theory?" What will happen to us, seekers of truth, if we actually find what we have been searching for and it turns out to be different than what we had hoped for? Where will we go when there is nowhere else to look for answers? Shell Beach is a rare peek behind the scenes of contemporary high-energy physics and mathematics, where Jesper Møller Grimstrup has been an insider in several of the key research communities such as loop quantum gravity and noncommutative geometry. In his book, Grimstrup invites the reader into the engine room of modern theoretical physics to see how this world works, who is in power, and what the struggle among researchers for ideas and academic position feels like. Shell Beach ends with the author taking the highly unusual step of creating a crowdfunding campaign for then as the first in the world to conduct his research outside of academia financed by private sponsors. Above all Shell Beach is a book about waterfalls. According to Grimstrup, doing research in theoretical physics is like kayaking huge waterfalls in slow-motion: "Our waterfalls are the ideas we pursue and like all big waterfalls you cannot scout them thoroughly from the riverbank - the only way to find out is to enter the main current and go over the edge". THE PRESS WROTE ABOUT THE DANISH EDITION: "Jesper Møller Grimstrup has written a formidable book. I have read many books about physics and science but none that compares to his book" - Jens Ramskov, Science Editor, Ing.dk" It hits the bullseye ... I followed all the trails, fascinated and nicely included. This is not an easy book to reference ... but if you seek the big question you'll end up with even more" - Maria Helleberg, POV-international

Download or read book String Theory and the Scientific Method written by Richard Dawid and published by Cambridge University Press. This book was released on 2013-05-02 with total page 213 pages. Available in PDF, EPUB and Kindle. Book excerpt: String theory has played a highly influential role in theoretical physics for nearly three decades and has substantially altered our view of the elementary building principles of the Universe. However, the theory remains empirically unconfirmed, and is expected to remain so for the foreseeable future. So why do string theorists have such a strong belief in their theory? This book explores this question, offering a novel insight into the nature of theory assessment itself. Dawid approaches the topic from a unique position, having extensive experience in both philosophy and high-energy physics. He argues that string theory is just the most conspicuous example of a number of theories in high-energy physics where non-empirical theory assessment has an important part to play. Aimed at physicists and philosophers of science, the book does not use mathematical formalism and explains most technical terms.

Download or read book The Road to Reality written by Roger Penrose and published by Vintage. This book was released on 2021-06-09 with total page 1136 pages. Available in PDF, EPUB and Kindle. Book excerpt: **WINNER OF THE 2020 NOBEL PRIZE IN PHYSICS** The Road to Reality is the most important and ambitious work of science for a generation. It provides nothing less than a comprehensive account of the physical universe and the essentials of its underlying mathematical theory. It assumes no particular specialist knowledge on the part of the reader, so that, for example, the early chapters give us the vital mathematical background to the physical theories explored later in the book. Roger Penrose's purpose is to describe as clearly as possible our present understanding of the universe and to convey a feeling for its deep beauty and philosophical implications, as well as its intricate logical interconnections. The Road to Reality is rarely less than challenging, but the book is leavened by vivid descriptive passages, as well as hundreds of hand-drawn diagrams. In a single work of colossal scope one of the world's greatest scientists has given us a complete and unrivalled guide to the glories of the universe that we all inhabit. 'Roger Penrose is the most important physicist to work in relativity theory except for Einstein. He is one of the very few people I've met in my life who, without reservation, I call a genius' Lee Smolin

Download or read book Cycles of Time written by Roger Penrose and published by Vintage. This book was released on 2011-09-06 with total page 307 pages. Available in PDF, EPUB and Kindle. Book excerpt: From Nobel prize-winner Roger Penrose, this groundbreaking book is for anyone "who is interested in the world, how it works, and how it got here" (New York Journal of Books). Penrose presents a new perspective on three of cosmology’s essential questions: What came before the Big Bang? What is the source of order in our universe? And what cosmic future awaits us? He shows how the expected fate of our ever-accelerating and expanding universe—heat death or ultimate entropy—can actually be reinterpreted as the conditions that will begin a new “Big Bang.” He details the basic principles beneath our universe, explaining various standard and non-standard cosmological models, the fundamental role of the cosmic microwave background, the paramount significance of black holes, and other basic building blocks of contemporary physics. Intellectually thrilling and widely accessible, Cycles of Time is a welcome new contribution to our understanding of the universe from one of our greatest mathematicians and thinkers.

Download or read book The Little Book of String Theory written by Steven S. Gubser and published by Princeton University Press. This book was released on 2010-02-08 with total page 184 pages. Available in PDF, EPUB and Kindle. Book excerpt: The essential beginner's guide to string theory The Little Book of String Theory offers a short, accessible, and entertaining introduction to one of the most talked-about areas of physics today. String theory has been called the "theory of everything." It seeks to describe all the fundamental forces of nature. It encompasses gravity and quantum mechanics in one unifying theory. But it is unproven and fraught with controversy. After reading this book, you'll be able to draw your own conclusions about string theory. Steve Gubser begins by explaining Einstein's famous equation E = mc2, quantum mechanics, and black holes. He then gives readers a crash course in string theory and the core ideas behind it. In plain English and with a minimum of mathematics, Gubser covers strings, branes, string dualities, extra dimensions, curved spacetime, quantum fluctuations, symmetry, and supersymmetry. He describes efforts to link string theory to experimental physics and uses analogies that nonscientists can understand. How does Chopin's Fantasie-Impromptu relate to quantum mechanics? What would it be like to fall into a black hole? Why is dancing a waltz similar to contemplating a string duality? Find out in the pages of this book. The Little Book of String Theory is the essential, most up-to-date beginner's guide to this elegant, multidimensional field of physics.

Download or read book Through Two Doors at Once written by Anil Ananthaswamy and published by Penguin. This book was released on 2019-06-11 with total page 306 pages. Available in PDF, EPUB and Kindle. Book excerpt: The intellectual adventure story of the "double-slit" experiment, showing how a sunbeam split into two paths first challenged our understanding of light and then the nature of reality itself--and continues to almost two hundred years later. Many of science's greatest minds have grappled with the simple yet elusive "double-slit" experiment. 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.

Download or read book Farewell to Reality written by Jim Baggott and published by Open Road Media. This book was released on 2013-08-06 with total page 454 pages. Available in PDF, EPUB and Kindle. Book excerpt: From acclaimed science author Jim Baggot, a lively, provocative, and “intellectually gratifying” critique of modern theoretical physics (The Economist). Where does one draw the line between solid science and fairy-tale physics? Jim Baggott argues that there is no observational or experimental evidence for many of the ideas of modern theoretical physics: super-symmetric particles, super strings, the multiverse, the holographic principle, or the anthropic cosmological principle. Unafraid to challenge prominent theorists, Baggott offers engaging portraits of many central figures of modern physics, including Stephen Hawking, Paul Davies, John D. Barrow, Brian Greene, and Leonard Susskind. Informed, comprehensive, and balanced, Farewell to Reality discusses the latest ideas about the nature of physical reality while clearly distinguishing between fact and fantasy, providing essential and entertaining reading for everyone interested in what we know and don’t know about the nature of the universe and reality itself.
