A mind-blowing glimpse into the near future, where quantum computing will have world-transforming effects.
The quantum computer is no longer the stuff of science fiction. Pioneering physicists are on the brink of unlocking a new quantum universe which provides a better representation of reality than our everyday experiences and common sense ever could. The birth of quantum computers - which, like Schrodinger's famous "dead and alive" cat, rely on entities like electrons, photons, or atoms existing in two states at the same time - is set to turn the computing world on its head.
In his fascinating study of this cutting-edge technology, John Gribbin updates his previous views on the nature of quantum reality, arguing for a universe of many parallel worlds where "everything is real." Looking back to Alan Turing's work on the Enigma machine and the first electronic computer, Gribbin explains how quantum theory developed to make quantum computers work in practice as well as in principle. He takes us beyond the arena of theoretical physics to explore their practical applications - from machines which learn through "intuition" and trial and error to unhackable laptops and smartphones. And he investigates the potential for this extraordinary science to create a world where communication occurs faster than light and teleportation is possible.
This is an exciting insider's look at the new frontier of computer science and its revolutionary implications.

SHORTLISTED FOR THE ROYAL SOCIETY INSIGHT INVESTMENT SCIENCE BOOK PRIZE 2019. 'An accessible primer on all things quantum' - Sunday Times Quantum physics is strange. It tells us that a particle can be in two places at once. Indeed, that particle is also a wave, and everything in the quantum world can be described entirely in terms of waves, or entirely in terms of particles, whichever you prefer. All of this was clear by the end of the 1920s. But to the great distress of many physicists, let alone ordinary mortals, nobody has ever been able to come up with a common sense explanation of what is going on. Physicists have sought 'quanta of solace' in a variety of more or less convincing interpretations. Popular science master John Gribbin takes us on a delightfully mind-bending tour through the 'big six', from the Copenhagen interpretation via the pilot wave and many worlds approaches. All of them are crazy, and some are more crazy than others, but in this world crazy does not necessarily mean wrong, and being more crazy does not necessarily mean more wrong.

Time travel is a familiar theme of science fiction, but is it really possible? Surprisingly, time travel is not forbidden by the laws of physics - and John Gribbin argues that if it is not impossible then it must be possible. Gribbin brilliantly illustrates the possibilities of time travel by comparing familiar themes from science fiction with their real-world scientific counterparts, including Einstein's theories of relativity, black holes, quantum physics, and the multiverse, illuminated by examples from the fictional tales of Robert Heinlein, Larry Niven, Carl Sagan and others. The result is an entertaining guide to some deep mysteries of the Universe which may leave you wondering whether time actually passes at all, and if it does, whether we are moving forwards or backwards. A must-read for science fiction fans and anyone intrigued by deep science.

'Gribbin casts a wide net and displays his breadth of knowledge in packing a lot into each chapter . . . a brief read, but one that may inspire readers to dig deeper.' Giles Sparrow, BBC Sky at Night Magazine A mind-warping excursion into the wildly improbable truths of science. Echoing Sherlock Holmes' famous dictum, John Gribbin tells us: 'Once you have eliminated the impossible, whatever is left, however improbable, is certainly possible, in the light of present scientific knowledge.' With that in mind, in his sequel to the hugely popular Six Impossible Things and Seven Pillars of Science, Gribbin turns his attention to some of the mind-bendingly improbable truths of science. For example: We know that the Universe had a beginning, and when it was - and also that the expansion of the Universe is speeding up. We can detect ripples in space that are one ten-thousandth the width of a proton, made by colliding black holes billions of light years from Earth. And, most importantly from our perspective, all complex life on Earth today is descended from a single cell - but without the stabilising influence of the Moon, life forms like us could never have evolved.

Obvious questions do not always have obvious answers. John Gribbin is known for giving us simple explanations of big concepts in science. But there is another way to probe the mysteries of the Universe and our place in it. Faced with persistent enquiries from his grandchildren, Gribbin realised that simple questions, such as 'Why is the sky blue?', sometimes require big answers, understandable in straightforward language. In answering those simple questions, he discovered that he was telling the story of our place in the Universe, from the Big Bang to the evolutionary reasons why men are, on average, bigger than women. The questions may be obvious, but the answers are sometimes surprising and highlight one of the main joys of science - discovering the unexpected. In this book, Gribbin invites the reader to join him on this voyage of discovery, where you may think you already know the answers but should be prepared to be surprised - or at least, tantalised by the truth.

'Gribbin has inspired generations with his popular science writing' Jim Al-Khalili A scintillating collection of short essays that really does cover 'life, the Universe, and everything'. From the mysteries of the subatomic world to the curious property of water that makes our planet inhabitable, master of popular science John Gribbin delves into the astonishing facts that underlie our existence. Some aspects of the quantum world really do seem impossible to 'common sense', but have been proved correct by experiments. Other features of the Universe appear obvious, such as the fact that atoms are mostly empty space. But this familiarity hides the truly amazing truths underpinning these observations. And some things merely seem improbable but are also hiding a Deep Truth, such as the fact that the Moon and Sun look the same size as viewed from Earth. This book will change forever the way you view the world. This volume brings together three of John Gribbin's successful science books: Six Impossible Things (which was Shortlisted for the Royal Society Insight Investment Science Books Prize in 2019), Seven Pillars of Science and Eight Improbable Possibilities.

John Gribbin, author of Six Impossible Things, shortlisted for the Royal Society Insight Investment Science Book Prize, presents a tour of seven fundamental scientific truths that underpin our very existence. These 'pillars of science' also defy common sense. For example, solid things are mostly empty space, so how do they hold together? There appears to be no special 'life force', so how do we distinguish living things from inanimate objects? And why does ice float on water, when most solids don't? You might think that question hardly needs asking, and yet if ice didn't float, life on Earth would never have happened. The answers to all of these questions were sensational in their day, and some still are. Throughout history, science has been able to think the unthinkable - and Gribbin brilliantly shows the surprising secrets on which our understanding of life is based.

The 20th century gave us two great theories of physics: the general theory of relativity, which describes the behaviour of things on a very large scale, including the entire Universe; and quantum theory, which describes the behaviour of things on a very small scale, the sub-atomic world. The refusal of the Universe to reveal an equation that combines these two great ideas has caused some people to doubt our whole understanding of physics. In this landmark new book, popular science master John Gribbin tells the dramatic story of the quest that has led us to discover the true age of the Universe (13.8 billion years) and the stars (just a little bit younger). This discovery, Gribbin argues, is one of humankind's greatest achievements and shows us that physics is on the right track to finding the 'Theory of Everything'. 13.8 provides an eye-opening look at this cutting-edge area of modern cosmology and physics, and tells the compelling story of what modern science has achieved - and what it can still achieve.

During the middle and late 1960s, concern about the way the world might be going began to move out of the arena of academic debate amongst specialists, and became a topic of almost everyday interest to millions of people. Concern about mankind's disruption of the natural balance of 'the environment' brought the term 'ecology' into widespread use, though not always with the meaning to be found in the dictionary, and fears that world population might be growing so rapidly that very soon we would run out of food, resulting in mass starvation and a disastrous collapse of civilisation, helped to make books such as The Limits to Growth best sellers in the early 1970s. Today, quite rightly, decisions on long-term policy with widespread repercussions - most notably, those concerning nuclear energy planning - are a subject of equally widespread public discussion. But all too often such debate focuses on specific issues without the prob lems ever being related effectively to an overall vision of where the world is going and how it is going to get there. At the Science Policy Res arch Unit, University of Sussex, a group working on studies of social and tech nological alternatives for the future has been contributing to 'the futures debate' for several years, cautiously (perhaps, in a sense, almost too cautiously ) developing a secure foundation for forecasting the way the world may develop."

The acclaimed author of In Search of Schrodinger's Cat searches for life on other planets Are we alone in the universe? Surely amidst the immensity of the cosmos there must be other intelligent life out there. Don't be so sure, says John Gribbin, one of today's best popular science writers. In this fascinating and intriguing new book, Gribbin argues that the very existence of intelligent life anywhere in the cosmos is, from an astrophysicist's point of view, a miracle. So why is there life on Earth and (seemingly) nowhere else? What happened to make this planet special? Taking us back some 600 million years, Gribbin lets you experience the series of unique cosmic events that were responsible for our unique form of life within the Milky Way Galaxy. Written by one of our foremost popular science writers, author of the bestselling In Search of Schrodinger's Cat Offers a bold answer to the eternal question, "Are we alone in the universe?" Explores how the impact of a "supercomet" with Venus 600 million years ago created our moon, and along with it, the perfect conditions for life on Earth From one of our most talented science writers, this book is a daring, fascinating exploration into the dawning of the universe, cosmic collisions and their consequences, and the uniqueness of life on Earth.

A Waterstones Best Book of 2020 The theory of evolution by natural selection did not spring fully formed and unprecedented from the brain of Charles Darwin. Rather it has been examined and debated by philosophers the world over for thousands of years. This lively history traces the evolution of the idea of evolution, showing how it has changed and been changed by different societies over time. It will put 'Darwin's Dangerous Idea' into its proper context, showing how it built on what went before and how it was developed in the twentieth century, through an understanding of genetics and the biochemical basis evolution. None of this diminishes the achievement of Darwin himself in perceiving the way evolution works at the level of individuals and species, but his contribution was one link in a chain that extends back into antiquity, and is still being forged today.

Shortlisted for the BSHS Hughes Prize What if Isaac Newton had never lived? Robert Hooke and Edmond Halley, whose place in history has been overshadowed by the giant figure of Newton, were pioneering scientists within their own right, and instrumental in establishing the Royal Society. Whilst Newton is widely regarded as one of the greatest scientists of all time, and the father of the English scientific revolution, John and Mary Gribbin uncover the fascinating story of Robert Hooke and Edmond Halley, whose scientific achievements neatly embrace the hundred years or so during which science as we know it became established in Britain. They argue persuasively that even without Newton science in Britain would have made a great leap forward in the second half of the seventeenth century, headed by two extraordinary men, Hooke and Halley.

A wonderfully readable account of scientifi c development over the past fi ve hundred years, focusing on the lives and achievements of individual scientists, by the bestselling author of In Search of Schrodinger's Cat
In this ambitious new book, John Gribbin tells the stories of the people who have made science, and of the times in which they lived and worked. He begins with Copernicus, during the Renaissance, when science replaced mysticism as a means of explaining the workings of the world, and he continues through the centuries, creating an unbroken genealogy of not only the greatest but also the more obscure names of Western science, a dot-to-dot line linking amateur to genius, and accidental discovery to brilliant deduction.
By focusing on the scientists themselves, Gribbin has written an anecdotal narrative enlivened with stories of personal drama, success and failure. A bestselling science writer with an international reputation, Gribbin is among the few authors who could even attempt a work of this magnitude. Praised as "a sequence of witty, information-packed tales" and "a terrifi c read" by The Times upon its recent British publication, The Scientists breathes new life into such venerable icons as Galileo, Isaac Newton, Albert Einstein and Linus Pauling, as well as lesser lights whose stories have been undeservedly neglected. Filled with pioneers, visionaries, eccentrics and madmen, this is the history of science as it has never been told before.

Accessible exploration of one of the most exciting areas of scientific inquiry - the nature of light. Following on from his bestseller, SCHRODINGER'S CAT, John Gribbin presents the recent dramatic improvements in experimental techniques that have enabled physicists to formulate and test new theories about the nature of light. He describes these theories not in terms of hard-to-imagine entities like spinning subnuclear particles, but in terms of the fate of two small cats, separated at a tender age and carried to opposite ends of the universe. In this way Gribbin introduces the reader to such new developments as quantum cryptography, through which unbreakable codes can be made, and goes on to possible future developments such as the idea that the ?entanglement' of quantum particles could be a way to build a STAR TREK style teleportation machine.

Why do traffic jams seem to happen for no apparent reason? Can major earthquakes be predicted? Why does the stock market have its ups and downs? How do species evolve? Where do galaxies come from? What is the origin of life on Earth? "What if all these questions had a single answer?
Over the past two decades, no field of scientific inquiry has had a more striking impact across a wide array of disciplines-from biology to physics, computing to meteorology-than that known as chaos and complexity, the study of complex systems. Now astrophysicist John Gribbin draws on his expertise to explore, in sparkling prose that communicates not only the wonder but the substance of cutting-edge science, the principles behind chaos and complexity. He reveals the remarkable ways these two revolutionary theories have been applied over the last twenty years to explain all sorts of phenomena-from weather patterns to mass extinctions.
Grounding these paradigm-shifting ideas in their historical context, Gribbin also traces their development from Newton to Darwin to Lorenz, Prigogine, and Lovelock, demonstrating how-far from overturning all that has gone before-chaos and complexity are the triumphant extensions of simple scientific laws. More astonishing, he shows how chaos and complexity permeate the universe on every scale, governing the evolution of life and galaxies alike. As profound as it is provocative, "Deep Simplicity takes us to the brink of understanding life itself.

The revolution is here. In breakthrough after breakthrough, pioneering physicists are unlocking a new quantum universe which provides a better representation of reality than our everyday experiences and common sense ever could. The birth of quantum computers - which, like Schroedinger's famous dead-and-alive cat, rely on entities like electrons existing in a mixture of states - is starting to turn the computing world on its head. In his fascinating study of this cutting-edge technology (first published as Computing with Quantum Cats and now featuring a new foreword), John Gribbin updates his previous views on the nature of quantum reality, arguing for a universe of many parallel worlds where 'everything is real'. Looking back to Alan Turing's work on the Enigma machine and the first electronic computer, Gribbin explains how quantum theory developed to make quantum computers work in practice as well as in principle. He takes us beyond the arena of theoretical physics to explore their practical applications - from machines which learn through 'intuition' and trial and error to unhackable laptops and smartphones. And he investigates the potential for this extraordinary science to allow communication faster than light and even teleportation, as we step into a world of infinite possibility.

Galaxies are the building blocks of the Universe: standing like islands in space, each is made up of many hundreds of millions of stars in which the chemical elements are made, around which planets form, and where on at least one of those planets intelligent life has emerged. Our own galaxy, the Milky Way, is just one of several hundred million other galaxies that we can now observe through our telescopes. Yet it was only in the 1920s that we realised that there is more to the Universe than the Milky Way, and that there were in fact other 'islands' out there. In many ways, modern astronomy began with this discovery, and the story of galaxies is therefore the story of modern astronomy. Since then, many exciting discoveries have been made about our own galaxy and about those beyond: how a supermassive black hole lurks at the centre of every galaxy, for example, how enormous forces are released when galaxies collide, how distant galaxies provide a window on the early Universe, and what the formation of young galaxies can tell us about the mysteries of Cold Dark Matter. In this Very Short Introduction, renowned science writer John Gribbin describes the extraordinary things that astronomers are learning about galaxies, and explains how this can shed light on the origins and structure of the Universe. ABOUT THE SERIES: The Very Short Introductions series from Oxford University Press contains hundreds of titles in almost every subject area.

John Gribbin, widely regarded as one of the best science writers of the 20th century, has also, unsurprisingly, been writing science fiction for many years. While his novels are well-known, his short stories are perhaps less so. He has also written under pseudonyms. Here, for the first time, is the definitive collection of John's short stories. Many were originally published in Analog and other magazines. Some were the seeds of subsequent novels. This collection contains 23 short stories, three of which John wrote with his son Ben. It also includes an essay in which John addresses the paradoxes of time travel in SF, and another in which John argues that the Moon is, in fact, a Babel Fish! These stories, written at a time when issues such as climate change were taken less seriously (especially by politicians) now seem very relevant again. What underpins all of them, of course, is a grounding in solid science. But also, which will not come as a surprise to anyone who has ever met John at a science fiction convention, or elsewhere, they are laced with a dry and subtle wit. He is, however, not averse to a good pun, as evidenced by the song he co-wrote for the Bonzo Dog Doo Dah Band: The Holey Cheeses of Nazareth. Despite the exhortation of this collection's title, this IS a perfect opportunity to look back at John's short stories. If you've never read any of his fiction before, now you have the chance to acquaint yourself with a body of work that, while being very much of its time, is certainly not in any way out of date.
