Our Big Bang, our distant future, parallel worlds, the sub-atomic and intergalactic - none of them are what they seem. But there is a way to understand this immense strangeness - mathematics. Seeking an answer to the fundamental puzzle of why our universe seems so mathematical, Tegmark proposes a radical idea: that our physical world not only is described by mathematics, but that it is mathematics. This may offer answers to our deepest questions: How large is reality? What is everything made of? Why is our universe the way it is?Table of ContentsPreface 1 What Is Reality?

    . .In You Are Here, bestselling author and celebrated astronaut Chris Hadfield creates a virtual orbit of Earth, giving us the really big picture: this is our home, from space. The millions of us who followed Hadfield's news-making Twitter feed from the ISS thought we knew what we were looking at when we first saw his photos. But we may have caught the beauty and missed the full meaning. Now, through photographs - many of which have never been shared - Hadfield unveils a fresh and insightful look at our planet. He sees astonishing detail and importance in these images, not just because he's spent months in space but because his in-depth knowledge of geology, geography and meteorology allows him to reveal the photos' mysteries.Featuring Hadfield's favourite images, You Are Here is divided by continent and represents one (idealized) orbit of the ISS. This planetary photo tour - surprising, playful, thought-provoking and visually delightful - provides a breathtakingly beautiful perspective on the wonders of the world. You Are Here opens a singular window on our planet, using remarkable photographs to illuminate the history and consequences of human settlement, the magnificence of newly uncovered landscapes, and the power of the natural forces shaping our world and the future of our species.

    Written by two of the world’s foremost authorities on space history, Hubble: Imaging Space and Time illuminates the solar system’s workings, the expansion of the universe, the birth and death of stars, the formation of planetary nebulae, the dynamics of galaxies, and the mysterious force known as "dark energy." The potential impact of this book cannot be overstressed: The 2008 servicing mission to install new high-powered scientific instruments is especially high profile because the cancellation of the previous mission, in 2004, caused widespread controversy. The authors reveal the inside story of Hubble’s beginnings, its controversial early days, the drama of its first servicing missions, and the creation of the dynamic images that reach into the deepest regions of visible space, close to the time when the universe began. A wealth of astonishing images leads us to the very edge of known space, setting the stage for the new James Webb Space Telescope, scheduled to launch in 2013. Find the stunning panoramic of Carina Nebula, detailing star birth as never before; a jet from a black hole in one galaxy striking a neighboring galaxy; a jewel-like collection of galaxies from the early years of the universe; and a giant galaxy cannibalizing a smaller galaxy. Timed for the 2008 shuttle launch and coinciding with the 400th anniversary of Galileo’s first telescope, Hubble: Imaging Space and Time accompanies a high-profile exhibit at the National Air and Space Museum and will be featured on the popular NASM website.

    But gravitational waves – ripples in the fabric of space and time – are unrelenting, passing through barriers that stop light dead.At the two 4-kilometre long LIGO observatories in the US, scientists developed incredibly sensitive detectors, capable of spotting a movement 100 times smaller than the nucleus of an atom. In 2015 they spotted the ripples produced by two black holes spiralling into each other, setting spacetime quivering.This was the first time black holes had ever been directly detected – and it promises far more for the future of astronomy. Brian Clegg presents a compelling story of human technical endeavour and a new, powerful path to understand the workings of the universe.Brian Clegg’s most recent books are The Reality Frame (Icon, 2017), What Colour is the Sun? (Icon, 2016) and Ten Billion Tomorrows (St Martin’s Press, 2016). His Dice World and A Brief History of Infinity were both longlisted for the Royal Society Prize for Science Books. He has also written Big Data for the Hot Science series. Brian has written for numerous publications including The Wall Street Journal, Nature, BBC Focus, Physics World, The Times and The Observer. Brian is editor of popularscience.co.uk and blogs at brianclegg.blogspot.com.

    The first is the astonishing achievement of the Human Genome Project, which, it was anticipated, would identify the genetic basis of those characteristics that distinguish humans from their primate cousins. The second is the phenomenal advance in brain imaging that now permits neuroscientists to observe the brain 'in action' and thus account for the remarkable properties of the human mind.But that is not how it has turned out. It is simply not possible to get from the monotonous sequence of genes along the Double Helix to the near infinite diversity of the living world, nor to translate the electrical firing of the brain into the creativity of the human mind. This is not a matter of not knowing all the facts. Rather, science has inadvertently discovered that its theories are insufficient to conjure the wonder of the human experience from the bare bones of our genes and brains.We stand on the brink of a tectonic shift in our understanding of ourselves that will witness the rediscovery of the central premise of Western philosophy that there is 'more than we can know'. Lucid, compelling and utterly engaging, ‘Why Us?’ offers a convincing and provocative vision of the new science of being human.

    The world is a different place after dark, and this breathtaking book illuminates the mesmerizing realm of all things nocturnal, with more than 250 glorious images.

Elegant, sexy, and a little mysterious, this richly illustrated book is a stunning pathway to some of the world's most captivating sights.

    In the past, discoveries often had to wait for the rise of the next generation to see questions in a new light and let go of old truisms. Today, in a world that is defined by a rapid rate of change, staying on the cutting edge has as much to do with shedding outdated notions as adopting new ones. In this spirit, John Brockman, publisher of the online salon Edge.org ("the world's smartest website"—The Guardian), asked 175 of the world's most influential scientists, economists, artists, and philosophers: What scientific idea is ready for retirement?Jared Diamond explores the diverse ways that new ideas emerge * Nassim Nicholas Taleb takes down the standard deviation * Richard Thaler and novelist Ian McEwan reveal the usefulness of "bad" ideas * Steven Pinker dismantles the working theory of human behavior * Richard Dawkins renounces essentialism * Sherry Turkle reevaluates our expectations of artificial intelligence * Physicist Andrei Linde suggests that our universe and its laws may not be as unique as we think * Martin Rees explains why scientific understanding is a limitless goal * Alan Guth rethinks the origins of the universe * Sam Harris argues that our definition of science is too narrow * Nobel Prize winner Frank Wilczek disputes the division between mind and matter * Lawrence Krauss challenges the notion that the laws of physics were preordained * plus contributions from Daniel Goleman, Mihaly Csikszentmihalyi, Nicholas Carr, Rebecca Newberger Goldstein, Matt Ridley, Stewart Brand, Sean Carroll, Daniel C. Dennett, Helen Fisher, Douglas Rushkoff, Lee Smolin, Kevin Kelly, Freeman Dyson, and others.

    On September 5, 1856, a submerged walnut tree pierced her hull, sinking the Arabia one-half mile below Parkville, Missouri. In time the river changed course, leaving the Arabia and her priceless freight deep beneath a Kansas farm field...The Arabia and her treasure seemed lost forever. Then, in 1988, four men and their families dedicated themselves to achieve what others could not; to recover the treasure from the Great White Arabia. Treasure hunter Greg Hawley chronicles his amazing story of perseverance and discovery. Lavishly illustrated and carefully documented, this book is a page turning adventure that immerses the reader into the thrilling discovery of buried treasure.

    He's certainly been thinking about it lately. May, a freshly minted astrophysics Ph.D., joins forces with legendary astronomer Patrick Moore and astrophysicist Chris Lintott in Bang! to consider the history of the universe from the Big Bang to Heat Death.Space, time, and matter were birthed 13.7 billion years ago and will continue on longer than we are able to comprehend. Infinitesimally small at first, the Universe is immense and ever expanding. Bang! explains how it all started, takes you on a tour of what is known about the evolution of the Universe, and posits how the end of time will come about.This fascinating book includes photographs, short biographies of key figures, an at-a-glance timeline, a glossary of terms, and suggested resources for further exploration.Based on the work of history’s most brilliant scientific minds, this amazing story features clear, straightforward discussions of the most perplexing and compelling aspects of existence—from the formation of stars, planets, and other galactic bodies to black holes, quasars, anti-matter, and dark matter to the emergence of life and the possibility that it could exist elsewhere.Pick up a copy of Bang! It will, it will rock you.

    Comparing gene sequences, examining atomic structures of proteins, and looking into the geochemistry of rocks have helped explain evolution in more detail than ever before. Nick Lane expertly reconstructs the history of life by describing the ten greatest inventions of evolution (including DNA, photosynthesis, sex, and sight), based on their historical impact, role in organisms today, and relevance to current controversies. Who would have guessed that eyes started off as light-sensitive spots used to calibrate photosynthesis in algae? Or that DNA’s building blocks form spontaneously in hydrothermal vents? Lane gives a gripping, lucid account of nature’s ingenuity, and the result is a work of essential reading for anyone who has ever pondered or questioned the science underlying evolution’s greatest gifts to man.

    These homeless dogs, plucked from the streets of Moscow, were selected because they fitted the program's criteria: weighing no more than 15 pounds, measuring no more than 14 inches in length, robust, photogenic and with a calm temperament. These characteristics enabled the dogs to withstand the extensive training that was needed to prepare them for suborbital, then for orbital, space fights. On 3 November 1957, the dog Laika was the first Earth-born creature to enter space, making her instantly famous around the world. She did not return. Her death, a few hours after launching, transformed her into a legendary symbol of sacrifice. Two further strays, Belka and Strelka, were the first beings to make it back from space, and were swiftly immortalized in children's books and cartoons. Images of the Space Dogs proliferated, reproduced on everyday goods across the Soviet Union: cigarette packets, tins of sweets, badges, stamps and postcards all bore their likenesses. "Soviet Space Dogs" uses these unique items to illustrate the story (in fact and fiction) of how they became fairytale idols. The first book to document these items, it contains more than 350 images, almost all of which are previously unpublished, and many of which have never been seen before outside Russia. The rich and varied ephemera (from cigarette packets to sweet wrappers and children's toys) of Soviet graphics will have immense appeal to the art and design market, as well as appealing to dog-lovers everywhere.

    Reflecting Goldsworthys lifelong interest in the landscape of the British Isles, its history, and the people who work on it, Enclosure is a collection of ephemeral work that relates to sheep, including a spectacular series of large sheep paintings--made by the hoof-prints of sheep.

    But the discoveries of the last few decades have changed all that, conjuring up instead a universe brimming with unpredictability, creativity, and chance. Writing with exceptional grace and clarity, Thuan vividly describes these important scientific discoveries, intriguing new theories about chaos, gravity, strange attractors, fractals, symmetry, superstrings, and the strangeness of atoms. Equally important, he reveals how these discoveries have shaped our view of the universe--for instance, how quantum mechanics brought indeterminism to the subatomic universe. Thuan deftly describes quantum mechanics, discusses its relationship to the theories of relativity (which deal inability to accept it. Indeed, throughout Chaos and Harmony, he makes clear as never before the mind-bending ideas of modern physics, such as the effect of gravity on time (it slows it down), the impossibility of crossing the speed-of-light barrier (it would actually reverse time), the role of fractals as the language of nature, and the unreasonable effectiveness of mathematics in understanding the universe. From the subatomic world to the vast realm of quasars and galaxies, from the nature of mathematics to the fractal characteristics of the human circulatory system, Trinh Xuan Thuan takes us on a breathtaking tour of the universe. With striking examples and clear, plain language, he shows how science has actually restored mystery to the world around us--a world of symmetry and chaos, contingency and creativity.

    As miraculous a feat of nature as the snowflakes has been, have we ever been truly able to appreciate this infinitesimal wonder in all its crystalline glory? Art of the Snowflake, as much a work of art as a testament to science, reveals how one of the snowflake's most inspired photographers came to such intimate knowledge of his craft and its fleeting focus. Beautiful pictures illustrate Kenneth Libbrecht's story of the microphotography of snow crystals, from the pioneering work of Wilson Bentley in the 1890s right up to Ken's own innovations in our age of digital images. A breathtaking look at the works of art that melt in an instant, this is a book to flip through and savor, season after season.
