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?

    Filled with data about the Earth, Moon, the planets, the stars, our Galaxy, and the myriad galaxies in deep space, it also reveals the latest scientific discoveries about black holes, quasars, and the origins of the Universe. Written by a premier astronomy expert, this book begins with a discussion of the Sun, from sunspots to solar eclipses. It then features over 100 tables on characteristics of the Moon, and the names, positions, sizes, and other key descriptors of all the planets and their satellites. The book tabulates solar and lunar eclipse, comets, close-approach asteroids, and significant meteor showers dates. Twenty-four maps show the surface features of the planets and their moons. The author then looks to the stars, their distances and movements, and their detailed classification and evolution. Forty-eight star charts cover both northern and southern hemispheres, enabling you to track down and name the main stars in all the constellations. The maps are supported by detailed tables of the names, positions, magnitudes, and spectra of the main stars in each constellation, along with key data on galaxies, nebulae, and clusters. There is a useful catalogue of the world's great telescopes and observatories, a history of astronomy and of space research, and biographies of 250 astronomers who have been most influential in developing the current understanding of the subject.

    Desperate for a solution, Camilla asked her mother if there was an instruction manual for humans that she could consult. But, without the blueprint to life, she was hoping for, Camilla began to create her own. Now armed with a PhD in biochemistry, Camilla dismantles our obscure social customs and identifies what it really means to be human using her unique expertise and a language she knows best: science.Through a set of scientific principles, this book examines life's everyday interactions including:- Decisions and the route we take to make them;- Conflict and how we can avoid it;- Relationships and how we establish them;- Etiquette and how we conform to it.Explaining Humans is an original and incisive exploration of human nature and the strangeness of social norms, written from the outside looking in. Camilla's unique perspective of the world, in turn, tells us so much about ourselves - about who we are and why we do it - and is a fascinating guide on how to lead a more connected, happier life.

    Together, they explain virtually everything about the world we live in. But, almost a century after their advent, most people haven't the slightest clue what either is about. Did you know that there's so much empty space inside matter that the entire human race could be squeezed into the volume of a sugar cube? Or that you grow old more quickly on the top floor of a building than on the ground floor? And did you realise that 1 percent of the static on a TV tuned between stations is a relic of the Big Bang?

    Keenly aware that the course of the nation's destiny lay westward—and that a "Voyage of Discovery" would be necessary to determine the nature of the frontier—President Thomas Jefferson commissioned Meriwether Lewis to lead an expedition from the Missouri River to the northern Pacific coast and back. From 1804 to 1806, accompanied by co-captain William Clark, the Shoshone guide Sacajawea, and thirty-two men, Lewis mapped rivers, traced the principal waterways to the sea, and established the American claim to the territories of Idaho, Washington, and Oregon. Together the captains kept this journal: a richly detailed record of the flora and fauna they sighted, the native tribes they encountered, and the awe-inspiring landscape they traversed, from their base camp near present-day St. Louis to the mouth of the Columbia River, that has become an incomparable contribution to the literature of exploration and the writing of natural history.

    Structured around a plane journey that sees encounters with substances from water and glue to coffee and wine, Liquid Rules shows how these liquids can bring death and destruction as well as wonder and fascination.From László Bíró's revolutionary pen and Abraham Gesner's kerosene to cutting-edge research on self-repairing roads and liquid computers, Miodownik uses his winning formula of scientific storytelling to bring the everyday to life. He reveals why liquids can flow up a tree but down a hill, why oil is sticky, how waves can travel so far, and how to make the perfect cup of tea. Here are the secret lives of substances.

    In 1969 we even walked on the moon. And yet as late as 2000, the earth’s deepest cave—the supercave—remained undiscovered. This is the story of the men and women who risked everything to find it, earning their place in history beside the likes of Peary, Amundsen, Hillary, and Armstrong. In 2004, two great scientist-explorers are attempting to find the bottom of the world. Bold, heroic American Bill Stone is committed to the vast Cheve Cave, located in southern Mexico and deadly even by supercave standards. On the other side of the globe, legendary Ukrainian explorer Alexander Klimchouk—Stone’s polar opposite in temperament and style, but every bit his equal in scientific expertise, physical bravery, and sheer determination—has targeted Krubera, a freezing nightmare of a supercave in the Republic of Georgia, where underground dangers are compounded by the horrors of separatist war in this former Soviet republic.

    Half-poet and half-geologist, he recorded his experiences and reflections in Travels in Alaska, a work he was in the process of completing at the time of his death in 1914. As Edward Hoagland writes in his Introduction, “A century and a quarter later, we are reading [Muir’s] account because there in the glorious fiords . . . he is at our elbow, nudging us along, prompting us to understand that heaven is on earth—is the Earth—and rapture is the sensible response wherever a clear line of sight remains.”This Modern Library Paperback Classic includes photographs from the original 1915 edition.

    This edition shows readers how to experience the wonders of the world and what creatures live in each habitat.

    In this book, he expands the points he has made, and claims that this debate is not so much about religion versus science, as about the nature of science itself. With infectious enthusiasm, he reveals the mechanics of evolutionary theory, explains how it is rooted in the testable and verifiable scientific method, and why it is therefore a sound explanation of our beginning. He argues passionately that to continue to assert otherwise, to continue to insist that creationism has a place in the science classroom is harmful not only to our children, but to the future of the greater world as well.

    Along the way, author Jonathan Wilson, an erudite and detailed writer who never loses a sense of the grand narrative sweep, takes a look at the lives of the great players and thinkers who shaped the game, and discovers why the English in particular have proved themselves so “unwilling to grapple with the abstract.” This is a modern classic of soccer writing that followers of the game will dip into again and again.

    Nobody is perfect. And that includes five of the greatest scientists in history—Charles Darwin, William Thomson (Lord Kelvin), Linus Pauling, Fred Hoyle, and Albert Einstein. But the mistakes that these great luminaries made helped advance science. Indeed, as Mario Livio explains, science thrives on error, advancing when erroneous ideas are disproven.As a young scientist, Einstein tried to conceive of a way to describe the evolution of the universe at large, based on General Relativity—his theory of space, time, and gravity. Unfortunately he fell victim to a misguided notion of aesthetic simplicity. Fred Hoyle was an eminent astrophysicist who ridiculed an emerging theory about the origin of the universe that he dismissively called “The Big Bang.” The name stuck, but Hoyle was dead wrong in his opposition.They, along with Darwin (a blunder in his theory of Natural Selection), Kelvin (a blunder in his calculation of the age of the earth), and Pauling (a blunder in his model for the structure of the DNA molecule), were brilliant men and fascinating human beings. Their blunders were a necessary part of the scientific process. Collectively they helped to dramatically further our knowledge of the evolution of life, the Earth, and the universe.
