John D. Barrow – författare

Is there any connection between the vastness of the universes of stars and galaxies and the existence of life on a small planet out in the suburbs of the Milky Way? This book shows that there is. In their classic work, John Barrow and Frank Tipler examine the question of Mankind's place in the Universe, taking the reader on a tour of many scientific disciplines and offering fascinating insights into issues such as the nature of life, the serach for extraterrestrial intelligence, and the past history and fate of our universe.

The constants of nature are the numbers that define the essence of the Universe. They tell us how strong its forces are, and what its fundamental laws can do: the strength of gravity, of magnetism, the speed of light, and the masses of the smallest particles of matter. They encode the deepest secrets of the Universe and express at once our greatest knowledge and our greatest ignorance about the cosmos. Their existence has taught us the profound truth that Nature abounds with unseen regularities. Yet, while we have become skilled at measuring the values of these constants, our frustrating inability to explain or predict their values shows how much we still have to learn about the inner workings of the Universe. What is the ultimate status of these constants of Nature? Are they truly constant? Could life have evolved and persisted if they were even slightly different? And are there other Universes where they are different? These are some of the issues that this book grapples with. It looks back to the discoveries of the first constants of Nature and the impact they had on scientists like Einstein. This book also tells the story of a tantalising new development in astronomy. For the first time astronomical observations are suggesting that some of the constants of Nature were different when the Universe was younger. So are our laws of Nature slowly changing? Is anything about our Universe immune from the ravages of time? Are there any constants of Nature at all?

How do you begin to understand the concept of nothing? Where does it begin and where does it end?From the zeros of the mathematician to the void of the philosophers, from Shakespeare to the empty set, from the ether to the quantum vacuum, from being and nothingness to creatio ex nihilo, there is much ado about nothing at the heart of things. Recent exciting discoveries in astronomy are shown to shed new light on the nature of the vacuum and its dramatic effect upon the explanation of the Universe. This remarkable book ranges over every nook and cranny of nothingness to reveal how the human mind has had to make something of nothing in every field of human enquiry.

‘A delight. Popular science doesn’t come much better than this’ IndependentEverything you might want to know about infinity - in history and all the way to today's cutting-edge science.Infinity is surely the strangest idea that humans have ever had. Where did it come from and what is it telling us about our Universe? Can there actually be infinities? Can you do an infinite number of things in a finite amount of time? Is the Universe infinite?Infinity is also the place where things happen that don't. What is it like to live in a Universe where nothing is original, where you can live forever, where anything that can be done, is done, over and over again?These are some of the deep questions that the idea of the infinite pushes us to ask. Throughout history, the infinite has been a dangerous concept. Many have lost their lives, their careers, or their freedom for talking about it. The Infinite Book will take you on a tour of these dangerous questions and the strange answers that scientists, mathematicians, philosophers and theologians have come up with to deal with its threats to our sanity.

What can we never do? Barrow looks at what limits there might be to human discovery, and what we might find, ultimately, to be unknowable, undoable, or unthinkable. Science is a big success story, but where will it end? And, indeed, will it end? Weaving together a tapestry of surprises, Barrow explores the frontiers of knowledge. We find that the notion of 'impossibility' has played a striking role in our thinking. Surrealism, impossible figures, time travel, paradoxes of logic and perspectives - all stimulate us to contemplate something more than what is. Using simple explanations, it shows the reader that impossibility is a deep and powerful notion; that any Universe complex enough to contain conscious beings will contain limits on what those beings can know about their Universe; that what we cannot know defines reality as surely as what we can know.

In this fascinating and entertaining collection of essays, acclaimed cosmologist and writer John D. Barrow addresses the many questions that we ponder in our quest to discover the universe. Key topics are: the popularity of Big Science, and physics and cosmology in particular; life on other planets; issues of time and space and quantum reality; the ancient foundations of science, mathematics and their most modern expression–complexity theory; and how science relates to religion and aesthetics. Taken as a whole, these thought-provoking essays provide a rich introduction to contemporary scientific debate. 'Only John Barrow could have assembled this delightful book of diverse essays, which touches on everything from the deepest secrets of Creation to the nature of art and esthetics. Witty, whimsical, and always thought-provoking and entertaining, Barrow takes us on a wild, intellectual joy-ride through the mysteries of spacetime and the mind.' Michio Kaku

In Impossibility, John D. Barrow--one of our most elegant and accomplished science writers--argues convincingly that there are limits to human discovery, that there are things that are ultimately unknowable, undoable, or unreachable. Barrow first examines the limits of the human mind: our brain evolved to meet the demands of our immediate environment, and much that lies outside this small circle may also lie outside our understanding. He investigates practical impossibilities, such as those imposed by complexity, uncomputability, or the finiteness of time, space, and resources. Is the universe finite or infinite? Can information be transmitted faster than the speed of light? The book also examines deeper theoretical restrictions on our ability to know, including Godel's theorem, which proved that there were things that could not be proved. Finally, having explored the limits imposed on us from without, Barrow considers whether there are limits we should impose upon ourselves. Weaving together this intriguing tapestry, Barrow illuminates some of the most profound questions of science, from the possibility of time travel to the very structure of the universe.

We live in a visual age, an age of images—iconic, instant, and influential—that have crystallized our conception of the large, the small, and the complex, of both inner and outer space. Some, like Robert Hooke's first microscopic views of the natural world, arose because of new technical capabilities. Others, like the first graphs, were breathtakingly simple but perennially useful. The first stunning picture of Earth from space stimulated an environmental consciousness that has grown ever since; the mushroom clouds from atomic and nuclear explosions became the ultimate symbol of death and destruction; Mercator's flat map of the Earth cemented an entire worldview. John D. Barrow's collection encompasses the frontiers of modern science and its most memorable historic moments. But this is much more than a picture book. Entertaining and informative essays accompany the powerful display of images that have illuminated concepts of far-reaching significance.

Have you ever considered why you always get stuck in the longest line? Why two’s company but three’s a crowd? Or why there are six degrees of separation instead of seven? In this hugely informative and endlessly entertaining book, John D. Barrow takes the most baffling of everyday phenomena and—with simple math, lucid explanations, and illustrations—explains why they work the way they do. His witty, crystal-clear answers shed light on the dark and shadowy corners of the physical world we all think we understand so well.

This volume provides a fascinating snapshot of the future of physics, covering fundamental physics, at the frontiers of research. It comprises a wide variety of contributions from leading thinkers in the field, inspired by the pioneering work of John A. Wheeler. Quantum theory represents a unifying theme within the book, along with topics such as the nature of physical reality, the arrow of time, models of the universe, superstrings, gravitational radiation, quantum gravity and cosmic inflation. Attempts to formulate a final unification of physics are discussed, along with the existence of hidden dimensions of space, space-time singularities, hidden cosmic matter, and the strange world of quantum technology.

This highly interdisciplinary 2007 book highlights many of the ways in which chemistry plays a crucial role in making life an evolutionary possibility in the universe. Cosmologists and particle physicists have often explored how the observed laws and constants of nature lie within a narrow range that allows complexity and life to evolve and adapt. Here, these anthropic considerations are diversified in a host of new ways to identify the most sensitive features of biochemistry and astrobiology. Celebrating the classic 1913 work of Lawrence J. Henderson, The Fitness of the Environment for Life, this book looks at the delicate balance between chemistry and the ambient conditions in the universe that permit complex chemical networks and structures to exist. It will appeal to a broad range of scientists, academics, and others interested in the origin and existence of life in our universe.
