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 Schrödinger'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, and featuring a new chapter on how the technology has evolved in recent years, 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.
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 "From the Hardcover edition.
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?
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 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.
The theory of evolution by natural selection did not spring fully formed and unprecedented from the brain of Charles Darwin. The idea of evolution had been around, in various guises, since the time of Ancient Greece. And nor did theorizing about evolution stop with what Daniel Dennett called "Darwin's dangerous idea." In this riveting new book, bestselling science writers John and Mary Gribbin explore the history of the idea of evolution, showing how Darwin's theory built on what went before and how it was developed in the twentieth century, through an understanding of genetics and the biochemical basis of evolution, into the so-called "modern synthesis" and beyond. Darwin deserves his recognition as the primary proponent of the idea of natural selection, but as the authors show, his contribution was one link in a chain that extends back into antiquity and is still being forged today.
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.
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.
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."
Critical acclaim for John Gribbin ""The master of popular science."" ""Gribbin explains things very well indeed, and there's not an
equation in sight."" ""Gribbin breathes life into the core ideas of complexity
science, and argues convincingly that the basic laws, even in
biology, will ultimately turn out to be simple."" ""Gribbin takes us through the basics of chaos theory] with his
customary talent for accessibility and clarity. His] arguments are
driven not by impersonal equations but by a sense of wonder at the
presence in the universe and in nature of simple, self-organizing
harmonies underpinning all structures, whether they are stars or
flowers."" ""In the true quantum realm, Gribbin remains the premier
expositor of the latest developments.""
Born in 1942, Stephen Hawking is no ordinary scientist. With a career that began over thirty years ago at Cambridge University, he has managed to do more than perhaps any other physicist to broaden our basic understanding of the universe. This skilful portrait of an indefatigable genius traces the course of Hawking's life and science, marrying biography and physics to tell the story of a remarkable man.
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.
President Franklin Delano Roosevelt said that “Thomas Jefferson, Benjamin Franklin, and Count Rumford are the greatest minds that America has produced,†and indeed, Rumford was a peer of theirs, and arguably contributed more to the scientific canon, and yet is nowhere near as well known. Born in the British Americas as Benjamin Thompson, he died a count and a knight, and lived a fascinating, eventful life in between, founding the Royal Institution in London, inventing a better chimney (still in widespread use) for open fires, finding time along the way to invent the coffee percolator and the enclosed oven, and most importantly pioneering our modern understanding of heat. White Knight, Red Heat tells the story of this notable figure in book form for the first time in over twenty years. Sir Benjamin Thompson, Count von Rumford, was an American-born British physicist, government administrator, and a founder of the Royal Institution of Great Britain, London. His investigations of heat overturned the theory that heat is a liquid form of matter and established the beginnings of the modern theory that heat is a form of motion. Loyal to the British crown, he served as a spy after the outbreak of the American Revolution, but in 1776 he was forced to flee to London, leaving his wife and daughter behind. Knighted by King George III in 1784, Thompson introduced numerous social reforms and brought James Watt’s steam engine into common use... He was created a Count of the Holy Roman Empire in 1791. Interest in gunpowder and weaponry stimulated his physical investigations, and in 1798 he began his studies of heat and friction, making one of the earliest measurements of the equivalence of heat and mechanical energy.
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.
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. These pocket-sized books are the perfect way to get ahead in a new subject quickly. Our expert authors combine facts, analysis, perspective, new ideas, and enthusiasm to make interesting and challenging topics highly readable.
Quantum theory is so shocking that Einstein could not bring himself to accept it. It is so important that it provides the fundamental underpinning of all modern sciences. Without it, we'd have no computers, no science of molecular biology, no understanding of DNA, no genetic engineering. In Search of Schrodinger's Cat tells the complete story of quantum mechanics, a truth stranger than any fiction. John Gribbin takes us step by step into an even more bizarre and fascinating place, requiring only that we approach it with an open mind. He introduces the scientists who developed quantum theory. He investigates the atom, radiation, time travel, the birth of the universe, super conductors and life itself. And in a world full of its own delights, mysteries and surprises, he searches for Schrodinger's Cat - a search for quantum reality - as he brings every reader to a clear understanding of the most important area of scientific study today - quantum physics. In Search of Schrodinger's Cat is a fascinating and delightful introduction to the strange world of the quantum - an essential element in understanding today's world.
'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.
