This is a fresh edition containing a wealth of new material that will enhance its already considerable reputation.

    The stewards of Earth, these organisms transformed the chemistry of our planet to make it habitable for plants, animals, and us. Life's Engines takes readers deep into the microscopic world to explore how these marvelous creatures made life on Earth possible--and how human life today would cease to exist without them.Paul Falkowski looks "under the hood" of microbes to find the engines of life, the actual working parts that do the biochemical heavy lifting for every living organism on Earth. With insight and humor, he explains how these miniature engines are built--and how they have been appropriated by and assembled like Lego sets within every creature that walks, swims, or flies. Falkowski shows how evolution works to maintain this core machinery of life, and how we and other animals are veritable conglomerations of microbes.A vibrantly entertaining book about the microbes that support our very existence, Life's Engines will inspire wonder about these elegantly complex nanomachines that have driven life since its origin. It also issues a timely warning about the dangers of tinkering with that machinery to make it more "efficient" at meeting the ever-growing demands of humans in the coming century.

    As we enter the year 2000, zero is once again making its presence felt. Nothing itself, it makes possible a myriad of calculations. Indeed, without zero mathematicsas we know it would not exist. And without mathematics our understanding of the universe would be vastly impoverished. But where did this nothing, this hollow circle, come from? Who created it? And what, exactly, does it mean? Robert Kaplan's The Nothing That Is: A Natural History of Zero begins as a mystery story, taking us back to Sumerian times, and then to Greece and India, piecing together the way the idea of a symbol for nothing evolved. Kaplan shows us just how handicapped our ancestors were in trying to figurelarge sums without the aid of the zero. (Try multiplying CLXIV by XXIV). Remarkably, even the Greeks, mathematically brilliant as they were, didn't have a zero--or did they? We follow the trail to the East where, a millennium or two ago, Indian mathematicians took another crucial step. By treatingzero for the first time like any other number, instead of a unique symbol, they allowed huge new leaps forward in computation, and also in our understanding of how mathematics itself works. In the Middle Ages, this mathematical knowledge swept across western Europe via Arab traders. At first it was called dangerous Saracen magic and considered the Devil's work, but it wasn't long before merchants and bankers saw how handy this magic was, and used it to develop tools likedouble-entry bookkeeping. Zero quickly became an essential part of increasingly sophisticated equations, and with the invention of calculus, one could say it was a linchpin of the scientific revolution. And now even deeper layers of this thing that is nothing are coming to light: our computers speakonly in zeros and ones, and modern mathematics shows that zero alone can be made to generate everything.Robert Kaplan serves up all this history with immense zest and humor; his writing is full of anecdotes and asides, and quotations from Shakespeare to Wallace Stevens extend the book's context far beyond the scope of scientific specialists. For Kaplan, the history of zero is a lens for looking notonly into the evolution of mathematics but into very nature of human thought. He points out how the history of mathematics is a process of recursive abstraction: how once a symbol is created to represent an idea, that symbol itself gives rise to new operations that in turn lead to new ideas. Thebeauty of mathematics is that even though we invent it, we seem to be discovering something that already exists.The joy of that discovery shines from Kaplan's pages, as he ranges from Archimedes to Einstein, making fascinating connections between mathematical insights from every age and culture. A tour de force of science history, The Nothing That Is takes us through the hollow circle that leads to infinity.

    Maggie Aderin-Pocock. In fact, she earned her nickname “Lunatic” because of her deep fascination for all things lunar. In her lucidly written, comprehensive guide to the moon, Aderin-Pocock takes readers on a journey to our closest celestial neighbor, exploring folklore, facts, and future plans.         She begins with the basics, unpacking everything from the moon’s topography and composition to its formation and orbit around the Earth. She travels back in time to track humanity’s relationship with the moon — beliefs held by ancient civilizations, the technology that allowed for the first moon landing, a brief history of moongazing, and how the moon has influenced culture throughout the years — and then to the future, analyzing the pros and cons of continued space travel and exploration. Throughout the book are sidebars, graphs, and charts to enhance the facts as well as black-and-white illustrations of the moon and stars. The Book of the Moon will be published for the 50th anniversary of the moon landing.

    This iconoclastic, witty, and extremely readable book illuminates the deep background of our place in nature and asks us to think critically about what science is, and what passes for it, in modern society.

    From India's sacred banyan tree to the fragrant cedar of Lebanon, they offer us sanctuary and inspiration – not to mention the raw materials for everything from aspirin to maple syrup.In Around the World in 80 Trees, expert Jonathan Drori uses plant science to illuminate how trees play a role in every part of human life, from the romantic to the regrettable. Stops on the trip include the lime trees of Berlin's Unter den Linden boulevard, which intoxicate amorous Germans and hungry bees alike, the swankiest streets in nineteenth-century London, which were paved with Australian eucalyptus wood, and the redwood forests of California, where the secret to the trees' soaring heights can be found in the properties of the tiniest drops of water.Each of these strange and true tales – populated by self-mummifying monks, tree-climbing goats and ever-so-slightly radioactive nuts – is illustrated by Lucille Clerc, taking the reader on a journey that is as informative as it is beautiful.

    In this fascinating book, Mario Livio tells the tale of a number at the heart of that mystery: phi, or 1.6180339887...This curious mathematical relationship, widely known as "The Golden Ratio," was discovered by Euclid more than two thousand years ago because of its crucial role in the construction of the pentagram, to which magical properties had been attributed. Since then it has shown a propensity to appear in the most astonishing variety of places, from mollusk shells, sunflower florets, and rose petals to the shape of the galaxy. Psychological studies have investigated whether the Golden Ratio is the most aesthetically pleasing proportion extant, and it has been asserted that the creators of the Pyramids and the Parthenon employed it. It is believed to feature in works of art from Leonardo da Vinci's Mona Lisa to Salvador Dali's The Sacrament of the Last Supper, and poets and composers have used it in their works. It has even been found to be connected to the behavior of the stock market!The Golden Ratio is a captivating journey through art and architecture, botany and biology, physics and mathematics. It tells the human story of numerous phi-fixated individuals, including the followers of Pythagoras who believed that this proportion revealed the hand of God; astronomer Johannes Kepler, who saw phi as the greatest treasure of geometry; such Renaissance thinkers as mathematician Leonardo Fibonacci of Pisa; and such masters of the modern world as Goethe, Cezanne, Bartok, and physicist Roger Penrose. Wherever his quest for the meaning of phi takes him, Mario Livio reveals the world as a place where order, beauty, and eternal mystery will always coexist.From the Hardcover edition.

    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.

    He turns out to be a bird who discusses maths with anyone who will listen.

    The planet most like ours, it has still been thought impossible to reach, let alone explore and inhabit.Now with the advent of a revolutionary new plan, all this has changed. leading space exploration authority Robert Zubrin has crafted a daring new blueprint, Mars Direct, presented here with illustrations, photographs, and engaging anecdotes.The Case for Mars is not a vision for the far future or one that will cost us impossible billions. It explains step-by-step how we can use present-day technology to send humans to Mars within ten years; actually produce fuel and oxygen on the planet's surface with Martian natural resources; how we can build bases and settlements; and how we can one day "terraform" Mars--a process that can alter the atmosphere of planets and pave the way for sustainable life.

    Until now. A Game for Hooligans brings the game's colourful story up to date to include the 2007 World Cup. It covers all of the great matches, teams and players but also explores the social, political and economic changes that have affected the course of rugby's development. It is an international history, covering not only Britain and France but also the great rugby powers of the southern hemisphere and other successful rugby nations, including Argentina, Fiji and Japan. Contained within are the answers to many intriguing questions concerning the game, such as why 1895 is the most important date in both rugby-union and rugby-league history and how New Zealand became so good and have remained so good for so long. There is also a wealth of anecdotes, including allegations of devil-worship at a Welsh rugby club and an account of the game's contribution to the Cuban Revolution. This is a must-read for any fan of the oval ball.

    Whether floating in a skiff on the Ganges as the Sun descends behind the funeral pyres of Varanasi, interviewing psychologists in the Norwegian Arctic about the effects of darkness, or watching tomato seedlings in southern Spain being hair-brushed (the better to catch the Sun's rays), Cohen tirelessly pursues his quarry. Drawing on more than seven years of research, he reports from locations in eighteen different countries, including the Novolazarevskaya science station in Antarctica (the coldest place on Earth); the Arizona desert (the sunniest); the Pope's observatory-cum-fortress outside Rome (possible the least accessible); and the crest of Mount Fuji, where--entirely alone--he welcomes the sunrise on the longest day of the year. As he soon discovers, the Sun is present everywhere--in mythology, language, religion, sciences, art, literature, and medicine; in the ocean depths; even atop the Statue of Liberty. Ancient worshippers believed our star was a man with three eyes and four arms, abandoned by his spouse because his brightness made her weary. The early Christians appropriated the halo from sun imagery and saw the cross as an emblem of the Sun and its rays. Galileo was the first to espy blemishes on the solar surface--sunspots--but hid his discoveries for fear of persecution. Einstein helped duplicate the source of the Sun's power to create the atomic bomb; while the "Sun King" Louis XIV, Chairman Mao, Adolf Hitler, and the Japanese emperors all co-opted the Sun to enlarge their authority. Conan Doyle had Sherlock Holmes declare that even thinking about the solar system took up too much space in his brain, while Richard Wagner had Tristan inveigh against daylight as the enemy of romantic love. Packed with interesting figures (the Sun is responsible for 44 percent of the world's tidal energy, and when aligned with the Moon, as at high tide, makes us all minutely taller); extraordinary myths (in India, just a few years ago, pregnant women were still being kept indoors during an eclipse, for fear their babies would be born blind or with cleft palates); and surprising anecdotes (during the Vietnam War, a large number of mines dropped into Haiphong harbor blew up simultaneously in response to a large solar flare), this splendidly illustrated volume is erudite, informative, and supremely entertaining. It not only explains the star that so inspires us, but shows how complex our relations with it have been--and continue to be.

    Scientific evidence, exciting new research, and the breakthrough discovery of an amazing Egyptian map prove without a doubt that this lost continent did exist...and reveal where its ruins can be found.But the fascinating truth about Atlantis also leads to a chilling conclusion about the environmental catastrophe that destroyed it.
