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.

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.

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.

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.

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

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.

When Paul Collins's son Morgan was two years old, he could read, spell, and perform multiplication tables in his head...but not answer to his own name. A casual conversation-or any social interaction that the rest of us take for granted-will, for Morgan, always be a cryptogram that must be painstakingly decoded. He lives in a world of his own: an autistic world. In Not Even Wrong, Paul Collins melds a memoir of his son's autism with a journey into this realm of permanent outsiders. Examining forgotten geniuses and obscure medical archives, Collins's travels take him from an English churchyard to the Seattle labs of Microsoft, and from a Wisconsin prison cell block to the streets of Vienna. It is a story that reaches from a lonely clearing in the Black Forest into the London palace of King George I, from Defoe and Swift to the discovery of evolution; from the modern dawn of the computer revolution to, in the end, the author's own household. Not Even Wrong is a haunting journey into the borderlands of neurology - a meditation on what "normal" is, and how human genius comes to us in strange and wondrous forms.
