On the Origin of Time - Stephen Hawking's final theory (Hardcover): Thomas Hertog On the Origin of Time - Stephen Hawking's final theory (Hardcover)
Thomas Hertog
R622 R510 Discovery Miles 5 100 Save R112 (18%) Ships in 9 - 15 working days

A new theory of the universe, twenty years in the making, by Stephen Hawking and his close collaborator Thomas Hertog. Perhaps the biggest question Stephen Hawking tried to answer in his extraordinary life was how the universe could have created conditions so perfectly hospitable to life. Pondering this mystery led Hawking to study the big bang origin of the universe, but his early work ran into a crisis when the maths predicted many big bangs producing a multiverse - countless different universes, most of which were far too bizarre to harbour life. Holed up in the theoretical physics department at Cambridge, Stephen Hawking and his friend and collaborator Thomas Hertog worked shoulder to shoulder for twenty years on a new quantum theory of the cosmos. As their discoveries took them deeper into the big bang, they were startled to find a deeper level of evolution in which the physical laws themselves transform and simplify until particles, forces, and even time itself fades away. Once upon a time, perhaps, there was no time. This led them to a revolutionary idea: the laws of physics are not set in stone but are born and co-evolve as the universe they govern takes shape. On the Origin of Time takes the reader on a quest to understand questions bigger than our universe, peering into the extreme quantum physics of black holes and the big bang and drawing on the latest developments in string theory. As Hawking's final days drew near, the two collaborators published a final theory proposing their radical new Darwinian perspective on the origins of our universe. Hertog offers a striking new vision that ties together, more deeply than ever, the nature of the universe's birth with our existence. Their theory profoundly transforms the way we think about our place in the order of the cosmos and may ultimately prove Hawking's biggest legacy.

Every night, above our heads, a drama of epic proportions is playing out. Diamond planets, zombie stars, black holes heavier than a billion Suns. The cast of characters is extraordinary, and each one has its own incredible story to tell. We once thought of our Earth as unique, but we have now discovered thousands of alien planets, and that's barely a fraction of the worlds that are out there. And there are more stars in the Universe than grains of sand on every planet in the Solar System. But amid all this vastness, the Milky Way Galaxy, our Sun and the Earth are home to the only known life in the Universe - at least for now. With a foreword from Professor Brian Cox, and access to all the latest stunning NASA photography, Andrew Cohen takes readers on a voyage of discovery, via the probes and telescopes exploring the outer reaches of our galaxy, revealing how it was formed and how it will inevitably be destroyed by the enigmatic black hole at its heart. And beyond our galaxy, the expanding Universe, which holds clues to the biggest mystery of all - how did it all begin? We now know more about those first moments of existence than we ever thought possible, and hidden in this story of how it all began are the clues to the fate of the Universe itself and everything in it.

A Nobel Prize-winning physicist explains what happened at the very beginning of the universe, and how we know, in this popular science classic. Our universe has been growing for nearly 14 billion years. But almost everything about it, from the elements that forged stars, planets, and lifeforms, to the fundamental forces of physics, can be traced back to what happened in just the first three minutes of its life. In this book, Nobel Laureate Steven Weinberg describes in wonderful detail what happened in these first three minutes. It is an exhilarating journey that begins with the Planck Epoch - the earliest period of time in the history of the universe - and goes through Einstein's Theory of Relativity, the Hubble Red Shift, and the detection of the Cosmic Microwave Background. These incredible discoveries all form the foundation for what we now understand as the "standard model" of the origin of the universe. The First Three Minutes examines not only what this model looks like, but also tells the exciting story of the bold thinkers who put it together. Clearly and accessibly written, The First Three Minutes is a modern-day classic, an unsurpassed explanation of where it is we really come from.

'A fascinating exploration of how we learned what matter really is, and the journey matter takes from the Big Bang, through exploding stars, ultimately to you and me.' - Sean Carroll, author of Something Deeply Hidden 'If you wish to make an apple pie from scratch, you must first invent the universe.' - Carl Sagan We probably all have a vague idea of how to make an apple pie: mix flour and butter, throw in some apples and you're probably most of the way there, right? Think again. Making an apple pie from scratch requires ingredients that definitely aren't available in the supermarket, ovens that can reach temperatures of trillions of degrees, and a preparation time of 13.8 billion years. Inspired by Sagan's famous line, Harry Cliff ventures out in search of the ultimate apple pie recipe, tracing the ingredients of our universe through the hearts of dying stars and back in time to a tiny fraction of a second after our universe began. Along the way, he confronts some really big questions: What is matter really made of? How does the stuff around us escape annihilation in the fearsome heat of the Big Bang? And will we ever be able to understand the very first moments of our universe? In pursuit of answers, Cliff ventures to the largest underground research facility in the world, deep beneath Italy's Gran Sasso mountains, where scientists gaze into the heart of the Sun using the most elusive of particles, the ghostly neutrino. He visits CERN in Switzerland to explore the 'Antimatter Factory' where this stuff of science fiction is manufactured daily (and we're close to knowing whether it falls upwards). And he reveals what the latest data from the Large Hadron Collider may be telling us about the fundamental ingredients of matter. Along the way, Cliff illuminates the history of physics, chemistry, and astronomy that brought us to our present understanding of the world, while offering readers a front-row seat to one of the most dramatic intellectual journeys human beings have ever embarked on. A transfixing deep dive into origins of our world, How to Make an Apple Pie from Scratch doesn't just put the makeup of our universe under the microscope, but the awe-inspiring, improbable fact that it exists at all.

"A Brief History of Time," published in 1988, was a landmark volume in science writing and in world-wide acclaim and popularity, with more than 9 million copies in print globally. The original edition was on the cutting edge of what was then known about the origins and nature of the universe. But the ensuing years have seen extraordinary advances in the technology of observing both the micro- and the macrocosmic world--observations that have confirmed many of Hawking's theoretical predictions in the first edition of his book.
Now a decade later, this edition updates the chapters throughout to document those advances, and also includes an entirely new chapter on Wormholes and Time Travel and a new introduction. It make vividly clear why "A Brief History of Time" has transformed our view of the universe.

We know the universe has a history, but does it also have a story of self-creation to tell? Yes, in Roy R. Gould’s account. He offers a compelling narrative of how the universe—with no instruction other than its own laws—evolved into billions of galaxies and gave rise to life, including humans who have been trying for millennia to comprehend it. Far from being a random accident, the universe is hard at work, extracting order from chaos. Making use of the best current science, Gould turns what many assume to be true about the universe on its head. The cosmos expands inward, not outward. Gravity can drive things apart, not merely together. And the universe seems to defy entropy as it becomes more ordered, rather than the other way around. Strangest of all, the universe is exquisitely hospitable to life, despite its being constructed from undistinguished atoms and a few unexceptional rules of behavior. Universe in Creation explores whether the emergence of life, rather than being a mere cosmic afterthought, may be written into the most basic laws of nature. Offering a fresh take on what brought the world—and us—into being, Gould helps us see the universe as the master of its own creation, not tethered to a singular event but burgeoning as new space and energy continuously stream into existence. It is a very old story, as yet unfinished, with plotlines that twist and churn through infinite space and time.

This is the inside story of one of the world's largest particle detectors. Two years ago, the ATLAS detector at the Large Hadron Collider in Geneva began investigating the most powerful particle collisions physicists have ever created. Its discoveries include evidence of a new particle that many think is the famous and long-sought Higgs boson. This book tells the story of one of the world's largest particle detectors, from its inception in the late 1980s to its construction in the 2000s and its first years of operation in the 2010s. You can find out why a machine designed to find tiny subatomic particles exceeds the height of the tallest dinosaurs, why the ATLAS detector throws away 99.998 per cent of the data it finds in the blink of an eye - and why its search for discoveries that will change the way we think about the universe has only just begun.

This new graduate textbook adopts a pedagogical approach to contemporary cosmology that enables readers to build an intuitive understanding of theory and data, and of how they interact, which is where the greatest advances in the field are currently being made. Using analogies, intuitive explanations of complex topics, worked examples and computational problems, the book begins with the physics of the early universe, and goes on to cover key concepts such as inflation, dark matter and dark energy, large‑scale structure, and cosmic microwave background. Computational and data analysis techniques, and statistics, are integrated throughout the text, particularly in the chapters on late-universe cosmology, while another chapter is entirely devoted to the basics of statistical methods. A solutions manual for end-of-chapter problems is available to instructors, and suggested syllabi, based on different course lengths and emphasis, can be found in the Preface. Online computer code and datasets enhance the student learning experience.

Is planet earth the end of the line, or is space itself the next stop?
Cyberspace. It's incredible, taking us to any part of the planet we want to visit. But as Paul Levinson shows in his brilliant new book, when it comes to transport, we're still stuck in the past, preferring to take our bodies with us. Whether it's trains, yachts, scooters or pogo-sticks, we're compelled to keep moving, our movements curtailed only by the earth itself. In our imaginations however, we soar way past the limits of current technology.
With a lucid but reflective style that takes in everything from robots and science fiction to religion and philosophy, Paul Levinson asks why there is a deep seated human desire to know what's 'out there'. Why, after getting a man on the moon, did the US space program develop so slowly? In a world where space is constantly repackaged, how do we know what real space is? Is our desire to get into space natural, or a religious craving, and is it a modern phenomenon, or did our ancestors also dream of escaping the clutches of Mother Earth?
Jam-packed with exciting, innovative, even revolutionary thinking about our future, Realspace is essential reading for everyone who has ever sat at their desk, gazed into the distance and imagined boarding a space shuttle...

Just as the recognition of social conventions in other cultures can lead to a more productive perspective on our own behaviour, so too a study of the cosmologies of other times and places can enable us recognise elements of our own cosmology that might otherwise pass as inevitable developments. Apart from modern natural science, therefore, this volume incorporates brief treatments of Native American, Cave-Dweller, Chinese, Egyptian, Islamic, Megalithic, Mesopotamian, Greek, Medieval and Copernican cosmology, leading to an appreciation of cosmology as an intellectual creation, not merely a collection of facts.

First published in 1973, this influential work discusses Einstein's General Theory of Relativity to show how two of its predictions arise: first, that the ultimate fate of many massive stars is to undergo gravitational collapse to form 'black holes'; and second, that there was a singularity in the past at the beginning of the universe. Starting with a precise formulation of the theory, including the necessary differential geometry, the authors discuss the significance of space-time curvature and examine the properties of a number of exact solutions of Einstein's field equations. They develop the theory of the causal structure of a general space-time, and use it to prove a number of theorems establishing the inevitability of singularities under certain conditions. A Foreword contributed by Abhay Ashtekar and a new Preface from George Ellis help put the volume into context of the developments in the field over the past fifty years.

Numerical relativity has emerged as the key tool to model gravitational waves - recently detected for the first time - that are emitted when black holes or neutron stars collide. This book provides a pedagogical, accessible, and concise introduction to the subject. Relying heavily on analogies with Newtonian gravity, scalar fields and electromagnetic fields, it introduces key concepts of numerical relativity in a context familiar to readers without prior expertise in general relativity. Readers can explore these concepts by working through numerous exercises, and can see them 'in action' by experimenting with the accompanying Python sample codes, and so develop familiarity with many techniques commonly employed by publicly available numerical relativity codes. This is an attractive, student-friendly resource for short courses on numerical relativity, as well as providing supplementary reading for courses on general relativity and computational physics.
