Yet they remain among the most mysterious of concepts. Is space an entity? Why does time have a direction? Could the universe exist without space and time? Can we travel to the past? Greene has set himself a daunting task: to explain non-intuitive, mathematical concepts like String Theory, the Heisenberg Uncertainty Principle, and Inflationary Cosmology with analogies drawn from common experience. From Newton’s unchanging realm in which space and time are absolute, to Einstein’s fluid conception of spacetime, to quantum mechanics’ entangled arena where vastly distant objects can instantaneously coordinate their behavior, Greene takes us all, regardless of our scientific backgrounds, on an irresistible and revelatory journey to the new layers of reality that modern physics has discovered lying just beneath the surface of our everyday world.

    Alternating passages of extraordinarily lucid mathematical exposition with chapters of elegantly composed biography and history, Prime Obsession is a fascinating and fluent account of an epic mathematical mystery that continues to challenge and excite the world.

    Marvel at the Dual Slit experiment as a tiny atom passes through 2 separate openings at the same time. Ponder the peculiar communication of quantum particles, which can remain in touch no matter how far apart. Join the genius jewel thief as he carries out a quantum measurement on a diamond without ever touching the object in question. With its clean, colorful layout and conversational tone, this text will hook you into the conundrum that is quantum mechanics.

    Drawing on string theory and space-time, quantum physics and chaos theory, award-winning science authors Mary and John Gribbin reveal how Pullman's 'His Dark Materials' trilogy is rooted in scientific truth.

    The subject was the mystery of prime numbers. At the heart of the presentation was an idea that Riemann had not yet proved but one that baffles mathematicians to this day.Solving the Riemann Hypothesis could change the way we do business, since prime numbers are the lynchpin for security in banking and e-commerce. It would also have a profound impact on the cutting-edge of science, affecting quantum mechanics, chaos theory, and the future of computing. Leaders in math and science are trying to crack the elusive code, and a prize of $1 million has been offered to the winner. In this engaging book, Marcus du Sautoy reveals the extraordinary history behind the holy grail of mathematics and the ongoing quest to capture it.

    Far less well-known is a much greater catastrophe that took place at the end of the Permian period 251 million years ago: 90 percent of life was destroyed, including saber-toothed reptiles and their rhinoceros-sized prey on land, as well as vast numbers of fish and other species in the sea.This book documents not only what happened during this gigantic mass extinction but also the recent rekindling of the idea of catastrophism. Was the end-Permian event caused by the impact of a huge meteorite or comet, or by prolonged volcanic eruption in Siberia? The evidence has been accumulating through the 1990s and into the new millennium, and Michael Benton gives his verdict at the very end. From field camps in Greenland and Russia to the laboratory bench, When Life Nearly Died involves geologists, paleontologists, environmental modelers, geochemists, astronomers, and experts on biodiversity and conservation. Their working methods are vividly described and explained, and the current disputes are revealed. The implications of our understanding of crises in the past for the current biodiversity crisis are also presented in detail. 46 b/w illustrations.

    Approaching science with a freshness unbound by convention or previous expectations, he produced some of the most original scientific thinking of the nineteenth century - and his discoveries went on to shape the twentieth century.

    Clear Science Teaching to Set the Stage for an Awe-Inspiring Course Created for a lay audience and readily accessible, in this course science always takes precedence over drama. The lectures are certainly entertaining, often funny, even awe-inspiring at times, as befits the subject matter. Even though you will be entertained, you will be learning good science. Clear introductions to essential principles of physics support these lectures, including density, quantum theory, gravity, and the General Theory of Relativity. Professor Neil deGrasse Tyson also includes forays into disciplines such as chemistry and biology as needed to explain events in astronomy. For example, Dr. Tyson begins one lecture at a point 13 billion years ago, when all space, matter, and energy in the known universe were contained in a volume less than one-trillionth the size of a pinpoint-about the size of a single atom. By the time he finishes, the cosmos has been stretched, the planets and our Earth formed, and 70 percent of existing Earth species have been wiped out by a gigantic asteroidclearing the way for the evolution of humanity. Along the way he has touched on Einstein's famous equation, E=mc2; on the four forces that were once unified in the early cosmos in a way physicists are still trying to explain; and on the chemical enrichment of the universe by exploding supernovae, which give the universe its necessary supply of heavier elements including oxygen, nitrogen, iron and, most important, carbon. Carbon, we learn, is a "sticky" atom, capable of making more kinds of molecules than all other elements combined. It's the ideal element with which to experiment in the building of life forms and is, of course, the element responsible for the remarkable diversity of life, including us. As Dr. Tyson notes, we are made of stardust, just as the planets are. And he has created a course that explains exactly how that came to be, beginning with a grounding in the basic "machinery" of matter, forces, and energy that has been discovered on Earth and which also reveals itself throughout the universe. The Stark and Violent Beauty of the Universe With this basic foundation in place, explanations of cosmic events fall logically into place, and the realities of the universe-including its eventual demise-are revealed in stark and often violent beauty. You learn: how Saturn's rings were formed, and why they will eventually be lost why low-density conditions are necessary to produce the drama of the northern and southern auroras why even the most jagged and wild of the Earth's mountain ranges are, from a cosmic standpoint, really part of a perfectly smooth sphere how black holes are formed and the extraordinary way in which they can wreak havoc in the universe how asteroids moving through space represent threats of extraordinary consequence to Earth, no matter how long those threats may take to be realized why the seemingly infinite panorama of celestial bodies revealed by the Hubble Space Telescope's famous "Deep Field" so intrigued astronomers how astronomers actually look for new planets, why the odds seem overwhelmingly in favor of some kind of life out there, whether we ever make contact or not. Most important, none of these ideas are presented as isolated "space factoids" that serve no purpose but to entertain. They are there to illustrate and reinforce the key principles of physics and astrophysics that are continually being presented in this course. But the inclusion of real science doesn't prevent Dr. Tyson from having some fun, either. When it's time to show how a black hole might remove one from the universe, he leads you right up to the "event horizon" and slips you in-feet first. Since the event horizon represents the point within which nothing, not even light, can escape, you might think this is a bad idea. And you would be right. But as you plummet toward the "singularity" at the heart of the black hole, you will learn firsthand about the interesting effects of gravity truly unleashed, including what physicists refer to, with a straight face, as "spaghettification." (Actually, Professor Tyson recommends that you be sucked in to a large black hole rather than a small one. You'll still be spaghettified, but it won't happen as quickly.) But make no mistake: Dr. Tyson does not consider the cosmos a laughing matter, this kind of whimsical touch notwithstanding. In spite of his training, he remains, admittedly, still in awe of his subject. And he has created a course that might well produce the same feeling in you.

    Armed with the extraordinary new discoveries about our genes, Ridley turns his attention to the nature versus nurture debate to bring the first popular account of the roots of human behaviour. What makes us who we are?In February 2001 it was announced that the genome contains not 100,000 genes as originally expected but only 30,000. This startling revision led some scientists to conclude that there are simply not enough human genes to account for all the different ways people behave: we must be made by nurture, not nature.Matt Ridley argues that the emerging truth is far more interesting than this myth. Nurture depends on genes, too, and genes need nurture. Genes not only predetermine the broad structure of the brain; they also absorb formative experiences, react to social cues and even run memory. They are consequences as well as causes of the will.Published fifty years after the discovery of the double helix of DNA, Nature via Nurture chronicles a new revolution in our understanding of genes. Ridley recounts the hundred years' war between the partisans of nature and nurture to explain how this paradoxical creature, the human being, can be simultaneously free-willed and motivated by instinct and culture. Nature via Nurture is an enthralling, up-to-the-minute account of how genes build brains to absorb experience.

    On its appearance in 1859 it was immediately recognized by enthusiasts and detractors alike as a work of the greatest importance: its revolutionary theory of evolution by means of natural selection provoked a furious reaction that continues to this day.The Origin of Species is here published together with Darwin’s earlier Voyage of the ‘Beagle.’ This 1839 account of the journeys to South America and the Pacific islands that first put Darwin on the track of his remarkable theories derives an added charm from his vivid description of his travels in exotic places and his eye for the piquant detail.(Book Jacket Status: Jacketed)

    The battles are conducted in the mystifying language of genetics. A handful of corporate "life science" giants, such as Monsanto, are pitted against a worldwide network of anticorporate ecowarriors like Greenpeace. And yet the possible benefits of biotech agriculture to our food supply are too vital to be left to either partisan.The companies claim to be leading a new agricultural revolution that will save the world with crops modified to survive frost, drought, pests, and plague. The greens warn that "playing God" with plant genes is dangerous. It could create new allergies, upset ecosystems, destroy biodiversity, and produce uncontrollable mutations. Worst of all, the antibiotech forces say, a single food conglomerate could end up telling us what to eat.In "Food, Inc., " acclaimed journalist Peter Pringle shows how both sides in this overheated conflict have made false promises, engaged in propaganda science, and indulged in fear-mongering. In this urgent dispatch, he suggests that a fertile partnership between consumers, corporations, scientists, and farmers could still allow the biotech harvest to reach its full potential in helping to overcome the problem of world hunger, providing nutritious food and keeping the environment healthy.

    Along the tidal rivers of Malaysia, thousands of fireflies congregate and flash in unison; the moon spins in perfect resonance with its orbit around the earth; our hearts depend on the synchronous firing of ten thousand pacemaker cells. While the forces that synchronize the flashing of fireflies may seem to have nothing to do with our heart cells, there is in fact a deep connection. Synchrony is a science in its infancy, and Strogatz is a pioneer in this new frontier in which mathematicians and physicists attempt to pinpoint just how spontaneous order emerges from chaos. From underground caves in Texas where a French scientist spent six months alone tracking his sleep-wake cycle, to the home of a Dutch physicist who in 1665 discovered two of his pendulum clocks swinging in perfect time, this fascinating book spans disciplines, continents, and centuries. Engagingly written for readers of books such as Chaos and The Elegant Universe, Sync is a tour-de-force of nonfiction writing.

    Neuroscience can now begin to unlock the key to the self. Our knowledge of the brain has progressed so rapidly that it will change the way we think of ourselves as human beings. It will change our notion of understanding. This is a revolution which will have impact on all our lives. Neuroscientists are gathering new empirical evidence about consciousness and human nature; they are picking up where the great earlier thinkers like Freud, Darwin, Charcot and others began. This evidence begins to give substance to some of the grand statements and intuitive leaps made in the nineteenth and early twentieth century about the nature of the self.

    Following closely behind is y, or gamma, a constant that arises in many mathematical areas yet maintains a profound sense of mystery. In a tantalizing blend of history and mathematics, Julian Havil takes the reader on a journey through logarithms and the harmonic series, the two defining elements of gamma, toward the first account of gamma's place in mathematics. Introduced by the Swiss mathematician Leonhard Euler (1707-1783), who figures prominently in this book, gamma is defined as the limit of the sum of 1 + 1/2 + 1/3 + . . . Up to 1/n, minus the natural logarithm of n--the numerical value being 0.5772156. . . . But unlike its more celebrated colleagues π and e, the exact nature of gamma remains a mystery--we don't even know if gamma can be expressed as a fraction. Among the numerous topics that arise during this historical odyssey into fundamental mathematical ideas are the Prime Number Theorem and the most important open problem in mathematics today--the Riemann Hypothesis (though no proof of either is offered!). Sure to be popular with not only students and instructors but all math aficionados, Gamma takes us through countries, centuries, lives, and works, unfolding along the way the stories of some remarkable mathematics from some remarkable mathematicians.-- "Notices of the American Mathematical Society"

    Ramachandran, now shares his unique insight into human consciousness in an entertaining, inspiring, and intellectually dazzling brief tour of the ultimate frontier—the thoughts in our heads.A Brief Tour of Human Consciousness is made up of five investigations of the greatest mysteries of the brain. The first chapter shows how amputees feel pain in limbs they no longer have as it introduces the great revolution of our age: neuroscience. The second chapter walks through the way what we see determines our thoughts, and demonstrates the counterintuitive point that believing is in fact seeing. The third chapter takes a leap beyond cutting edge science to audaciously set out a general theory of beauty, explaining why, the world over, cultures have fundamentally similar notions of what is attractive. The fourth chapter explores the bizarre world of synesthetes, people who see colors in numbers, textures in smells, sounds in sights, and flavors in sounds. Finally, V. S. Ramachandran one of the foremost brain researchers in the world today, sums up the implications of the revolution in our understanding of consciousness, to make a fascinating argument about our essential sense of self and its distributed nature.

    Covered by a dull grey membrane, it resembles a gigantic, convoluted fungus. Its inscrutability has captivated scientists, philosophers and artists for centuries. It is, of course, the human brain. With the help of science we can now begin to understand the extraordinary complexity of the brain's circuits: we can see which nerve cells generate electricity as we fall in love, tell a lie or dream of a lottery win. And inside the 100 billion cells of this rubbery network is something remarkable: you.In this entertaining and accessible book, Robert Winston takes us deep into the workings of the human mind and shows how our emotions and personality are the result of genes and environment. He explains how memories are formed and lost, how the ever-changing brain is responsible for toddler tantrums and teenage angst, plus he reveals the truth behind extra-sensory perception, déjà vu and out-of-body experiences. He also tells us how to boost our intelligence, how to tap into creative powers we never knew we had, how to break old habits and keep our brain fit and active as we enter old age.The human mind is all we have to help us to understand it. Paradoxically, it is possible that science may never quite explain everything about this extraordinary mechanism that makes each of us unique.

    Is life written into the laws of nature, or just a bizarre accident, unique in the universe? How can a mix of non-living chemicals be transformed into something as complex as the living cell? Acclaimed physicist, astrobiologist and writer Paul Davies presents evidence that life began billions of years ago kilometres underground, arguing that it may well have started on Mars and spread to Earth in rocks blasted off the Red Planet by asteroid impacts. This solution to the riddle of life's origin has sweeping implications for the nature of the universe and our place within it, and opens the way to a radical rethinking of where we came from. 'One of a handful of first-rate scientists who are popular writers. If you are going to read only one book on the origin of life, seriously consider this one'  The New York Times 'The best science writer on either side of the Atlantic'  Washington Times 'Davies succeeds not only in being provocative and controversial, but in maintaining the rigorous scientific approach of the physicist... a classic example of how to present a scientific case, and an insight into the way good scientists work'  John Gribbin, Independent Paul Davies has achieved an international reputation for his ability to explain the significance of advanced scientific ideas in simple language. He is the author of some twenty books, including Superforce, God and the New Physics, The Mind of God, The Last Three Minutes, Are We Alone? and How to Build a Time Machine.

    There are more than 10,000 varieties of wildflowers in North America, some rare, some so plentiful that they are designated as invasive weeds. Each has a unique story.There's Bouncing Bet, a perennial common along the roads and railroad tracks of America. Like many of our most abundant summer wildflowers, Bet was brought over to fill colonial gardens. It's a beautiful plant, but also a useful one. Open up the stalk and its sap makes a fine soap. Colonial beermakers used to put a dab in to help the head on a brew. Doctors used it to wash wounds. Generally considered a weed, it's everywhere.Or Coltsfoot, which pops up almost alone in winters, and was used in New England as a cure for coughs, the leaves boiled down in water. Asthmatics, Sanders tells us, used to smoke it for relief. For many years, apothecaries in France used Coltsfoot as its symbol, a surprising pedigree for a neglected "weed."More a companion than a field guide, THE SECRETS OF WILDFLOWERS is a must-have for anyone who enjoys a walk in a meadow or a gaze outside.

    In Magic Universe, he draws on his vast experience to offer readers a lively, far-reaching look at modern science in all its glory, shedding light on the latest ideas in physics, biology, chemistry, medicine, astronomy, and many other fields. What is truly magical about Magic Universe is Calder's incredible breadth. Migrating birds, light sensors in the human eye, black holes, antimatter, buckyballs and nanotubes--with exhilarating sweep, Calder can range from the strings of a piano to the superstrings of modern physics, from Pythagoras's theory of musical pitch to the most recent ideas about atoms and gravity and a ten-dimensional universe--all in one essay. The great virtue of this wide-ranging style--besides its liveliness and versatility--is that it allows Calder to illuminate how the modern sciences intermingle and cross-fertilize one another. Indeed, whether discussing astronauts or handedness or dinosaurs, Calder manages to tease out hidden connections between disparate fields of study. What is most wondrous about the magic universe is that one can begin with stellar dust and finish with life itself. Drawing on interviews with more than 200 researchers, from graduate students to Nobel prize-winners, Magic Universe takes us on a high-spirited tour through the halls of science, one that will enthrall everyone interested in science, whether a young researcher in a high-tech lab or an amateur buff sitting in the comfort of an armchair.

    The case rests on a remarkable compilation of examples of convergent evolution, in which two or more lineages have independently evolved similar structures and functions. The examples range from the aerodynamics of hovering moths and hummingbirds to the use of silk by spiders and some insects to capture prey. Going against the grain of Darwinian orthodoxy, this book is a must read for anyone grappling with the meaning of evolution and our place in the Universe. Simon Conway Morris is the Ad Hominen Professor in the Earth Science Department at the University of Cambridge and a Fellow of St. John's College and the Royal Society. His research focuses on the study of constraints on evolution, and the historical processes that lead to the emergence of complexity, especially with respect to the construction of the major animal body parts in the Cambrian explosion. Previous books include The Crucible of Creation (Getty Center for Education in the Arts, 1999) and co-author of Solnhofen (Cambridge, 1990). Hb ISBN (2003) 0-521-82704-3

    Lancaster provides the definitive rebuttal of evolutionary just-so stories about men, women, and the nature of desire in this spirited exposé of the heterosexual fables that pervade popular culture, from prime-time sitcoms to scientific theories about the so-called gay gene. Lancaster links the recent resurgence of biological explanations for gender norms, sexual desires, and human nature in general with the current pitched battles over sexual politics. Ideas about a "hardwired" and immutable human nature are circulating at a pivotal moment in human history, he argues, one in which dramatic changes in gender roles and an unprecedented normalization of lesbian and gay relationships are challenging received notions and commonly held convictions on every front.The Trouble with Nature takes on major media sources—the New York Times, Newsweek—and widely ballyhooed scientific studies and ideas to show how journalists, scientists, and others invoke the rhetoric of science to support political positions in the absence of any real evidence. Lancaster also provides a novel and dramatic analysis of the social, historical, and political backdrop for changing discourses on "nature," including an incisive critique of the failures of queer theory to understand the social conflicts of the moment. By showing how reductivist explanations for sexual orientation lean on essentialist ideas about gender, Lancaster invites us to think more deeply and creatively about human acts and social relations.

    The germ revolution came after two decades of scientific virtuosity, outstanding feats of intellectual courage and bitter personal rivalries, doctors at last recognised that infectious diseases are caused by mircoscopic organisms.

    This book brings to our attention the Wellcome museum that he set up, initially a collection of curios for his amusement and to aid students in their medical research. Packed full of photographs, these seven essays approach different aspects of the museum and its collection including its priceless and its banal artefacts. Ghislaine Lawrence looks at the development of the Museum for the Science of History, Francis Knight explores the Wellcome library, the archaeological interests of Wellcome are discussed by Chris Gosden where as John Mack turns his attention to medicine and anthropology. The final two essays look at Wellcome's contribution to modern medicine (John Pickstone) and the human remains within this collection (Ruth Richardson). The book accompanies an exhibition at the British Museum.

    Examining such readily observable phenomena, this book introduces readers to the beauty of nature as revealed by mathematics and the beauty of mathematics as revealed in nature.Generously illustrated, written in an informal style, and replete with examples from everyday life, Mathematics in Nature is an excellent and undaunting introduction to the ideas and methods of mathematical modeling. It illustrates how mathematics can be used to formulate and solve puzzles observed in nature and to interpret the solutions. In the process, it teaches such topics as the art of estimation and the effects of scale, particularly what happens as things get bigger. Readers will develop an understanding of the symbiosis that exists between basic scientific principles and their mathematical expressions as well as a deeper appreciation for such natural phenomena as cloud formations, halos and glories, tree heights and leaf patterns, butterfly and moth wings, and even puddles and mud cracks.Developed out of a university course, this book makes an ideal supplemental text for courses in applied mathematics and mathematical modeling. It will also appeal to mathematics educators and enthusiasts at all levels, and is designed so that it can be dipped into at leisure.

    Chasing terror money, she takes the reader from CIA headquarters to the smuggling routes of the Far East, from the back rooms of Wall Street to hawala exchanges in the Middle East. Napoleoni describes the "New Economy of Terror," "a fast-growing international economic system with a turnover of about $1.5 trillion [that] is challenging Western hegemony." It is made up of illegal businesses such as arms and narcotics trading, and oil and diamond smuggling, as well as charitable donations and legal profits. Napoleoni reveals the interdependency between economies run by armed groups and western economies, and provides a pioneering examination of the system and methods by which international terrorism is financed.

    Dazzle your students with Peculiar number patterns and properties Clever shortcuts and tricks for avoiding cumbersome mathematic processes Curious problems that reveal problem-solving strategies Algebra problems that shed light on patterns in mathematics and the behavior of numbers Activities and demonstrations that uncover timeless geometric principles Used as attention-getters, motivators, or enrichment activities, these math wonders leave students questioning and exploring further, regardless of their grade level or ability.

    Sartorius, Epicurus, Libido ... these are the signs of the Chap zodiac. If the manifesto was a call to arms - gentlemen of the world unite, you have exquisite manners to maintain! - then the almanac is a practical guide on how to uphold these standards through the year.

    Oliver Sacks, "the poet laureate of medicine" New York Times writes that "the best science writing . . . cannot be completely 'objective' -- how can it be when science itself is so human an activity? -- but it is never self-indulgently subjective either. It is, at best, a wonderful fusion, as factual as a news report, as imaginative as a novel." Following this definition of "good" science writing, Dr. Sacks has selected the twenty-five extraordinary pieces in the latest installment of this acclaimed annual.This year, Peter Canby travels into the heart of remote Africa to track a remarkable population of elephants; with candor and tenderness, Floyd Skloot observes the toll Alzheimer's disease is taking on his ninety-one-year-old mother, and is fascinated by the memories she retains. Gunjan Sinha explores the mating behavior of the common prairie vole and what it reveals about the human pattern of monogamy. Michael Klesius attempts to solve what Darwin called "an abominable mystery": How did flowers originate? Lawrence Osborne tours a farm where a genetically modified goat produces the silk of spiders in its milk. Joseph D'Agnese visits a home for retired medical research chimps. And in the collection's final piece, Richard C. Lewontin and Richard Levins reflect on how the work of Stephen Jay Gould demonstrated the value of taking a radical approach to science.As Dr. Sacks writes of Stephen Jay Gould -- to whose memory this year's anthology is dedicated -- an article of his "was never predictable, never dry, could not be imitated or mistaken for anybody else's." The same can be said of all of the good writing contained in this diverse collection.
