The rest is hidden. This could be the biggest puzzle that science has ever faced. Since the 1970s, astronomers have been aware that galaxies have far too little matter in them to account for the way they spin around: they should fly apart, but something concealed holds them together. That ’something' is dark matter – invisible material in five times the quantity of the familiar stuff of stars and planets. By the 1990s we also knew that the expansion of the universe was accelerating. Something, named dark energy, is pushing it to expand faster and faster. Across the universe, this requires enough energy that the equivalent mass would be nearly fourteen times greater than all the visible material in existence. Brian Clegg explains this major conundrum in modern science and looks at how scientists are beginning to find solutions to it.

    Why is the universe expanding at an ever faster rate? What is the nature of the "dark matter" that makes up almost a quarter of the universe? Why does the universe appear fine-tuned for life? Are there others besides our own? Ananthaswamy soon finds himself at the ends of the earth--in remote and sometimes dangerous places. Take the Atacama Desert in the Chilean Andes, one of the coldest, driest places on the planet, where not even a blade of grass can survive. Its spectacularly clear skies and dry atmosphere allow astronomers to gather brilliant images of galaxies billions of light-years away. Ananthaswamy takes us inside the European Southern Observatory's Very Large Telescope on Mount Paranal, where four massive domes open to the sky each night "like dragons waking up."He also takes us deep inside an abandoned iron mine in Minnesota, where half-mile-thick rock shields physicists as they hunt for elusive dark matter particles. And to the East Antarctic Ice Sheet, where engineers are drilling 1.5 miles into the clearest ice on the planet. They're building the world's largest neutrino detector, which could finally help reconcile quantum physics with Einstein's theory of general relativity.The stories of the people who work at these and other dramatic research sites--from Lake Baikal in Siberia to the Indian Astronomical Observatory in the Himalayas to the subterranean lair of the Large Hadron Collider--make for a compelling new portrait of the universe and our quest to understand it. An atmospheric, engaging, and illuminating read, "The Edge of Physics" depicts science as a human process, bringing cosmology back down to earth in the most vivid terms.

    Yet recent theories suggest that there is far more to the universe than what our instruments record--in fact, it could be infinite. Colossal flows of galaxies, large empty regions called voids, and other unexplained phenomena offer clues that our own "bubble universe" could be part of a greater realm called the multiverse. How big is the observable universe? What it is made of? What lies beyond it? Was there a time before the Big Bang? Could space have unseen dimensions? In this book, physicist and science writer Paul Halpern explains what we know--and what we hope to soon find out--about our extraordinary cosmos.Explains what we know about the Big Bang, the accelerating universe, dark energy, dark flow, and dark matter to examine some of the theories about the content of the universe and why its edge is getting farther away from us fasterExplores the idea that the observable universe could be a hologram and that everything that happens within it might be written on its edgeWritten by physicist and popular science writer Paul Halpern, whose other books include "Collider: The Search for the World's Smallest Particles," and "What's Science Ever Done For Us: What the Simpsons Can Teach Us About Physics, Robots, Life, and the Universe"

    Although Einstein understood that black holes were mathematical solutions to his equations, he never accepted their physical reality--a viewpoint many shared. This all changed in the 1960s and 1970s, when a deeper conceptual understanding of black holes developed just as new observations revealed the existence of quasars and X-ray binary star systems, whose mysterious properties could be explained by the presence of black holes. Black holes have since been the subject of intense research--and the physics governing how they behave and affect their surroundings is stranger and more mind-bending than any fiction.After introducing the basics of the special and general theories of relativity, this book describes black holes both as astrophysical objects and theoretical "laboratories" in which physicists can test their understanding of gravitational, quantum, and thermal physics. From Schwarzschild black holes to rotating and colliding black holes, and from gravitational radiation to Hawking radiation and information loss, Steven Gubser and Frans Pretorius use creative thought experiments and analogies to explain their subject accessibly. They also describe the decades-long quest to observe the universe in gravitational waves, which recently resulted in the LIGO observatories' detection of the distinctive gravitational wave "chirp" of two colliding black holes--the first direct observation of black holes' existence.The Little Book of Black Holes takes readers deep into the mysterious heart of the subject, offering rare clarity of insight into the physics that makes black holes simple yet destructive manifestations of geometric destiny.

    Though the human spirit has not been broken, the new rules of survival are harsh and barbaric. As barons fight for power in a savage new America, power is claimed with the salvaged arsenels of a predark world: weapons, gasoline and those willing to kill.The Marshall Islands, once the testing grounds for twentieth-century weapons of mass destruction, remains perversely beautiful. But the infested waters become the battleground for looting pirates and sec men in still-functional navy PT boats, all driven by greed and madness to plunder the predark caches of science and technology hidden in the islands. Ryan Cawdor and his warrior band emerge in this perilous waterworld, caught in a grim fight to unlock the secrets of the past.In the Deathlands, the price for survival is high.

    In the late 1920s, astronomers defeated this assumption with a startling new discovery. From Earth, the light of distant galaxies appeared to be red, meaning that those galaxies were receding from us. This led to the revolutionary realization that the universe is expanding. The Red Limit is the tale of this discovery, its ramifications, and the passionately competitive astronomers who charted the past, present, and future of the cosmos.

    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.

    * A large cross-section of organic reactions/mechanisms given with stereochemical implications. * Relationship between conformation and reactivity specially highlighted. * Instrumentation techniques relating to stereochemical investigation discussed in simple language.ABOUT THE BOOK:During recent years, stereochemistry has undergone a phenomenal growth both in theory and practice, with a concomitant increase of interest among the organic chemists, biological chemists, medicinal chemists, and pharmacologists. The present text provides an up-to-date, coherent, and comprehensive account of the subject starting from the fundamentals and leading up to the latest developments as far as practicable. Emphasis has been placed on a symmetry-based approach to molecular chirality, stereochemical terminologies (modern stereochemistry is replete with them), topicity and prostereoisomerism, conformational analysis, dynamic stereochemistry, chiroptical properties, and assignment of absolute configuration to chiral molecules. Dynamic stereochemistry has been discussed with reference to conformation-reactivity correlation, stereoselective synthesis, and pericyclic reactions. A large cross-section of organic reactions with stereochemical implication has been incorporated. Attempts have been made to familiarise the readers with modern instrumental techniques, nuclear magnetic resonance in particular, used for stereochemical investigation. Each chapter is provided with a summary which highlights the main points of the text.

    But almost everything about it, from the elements that forged stars, planets, and lifeforms, to the fundamental forces of physics, can be traced back to what happened in just the first three minutes of its life.In this book, Nobel Laureate Steven Weinberg describes in wonderful detail what happened in these first three minutes. It is an exhilarating journey that begins with the Planck Epoch - the earliest period of time in the history of the universe - and goes through Einstein's Theory of Relativity, the Hubble Red Shift, and the detection of the Cosmic Microwave Background. These incredible discoveries all form the foundation for what we now understand as the "standard model" of the origin of the universe. The First Three Minutes examines not only what this model looks like, but also tells the exciting story of the bold thinkers who put it together.Clearly and accessibly written, The First Three Minutes is a modern-day classic, an unsurpassed explanation of where it is we really come from.

    The DOs chronicles the development of this controversial medical movement from the nineteenth century to the present. Historian Norman Gevitz describes the philosophy and practice of osteopathy, as well as its impact on medical care. From the theories underlying the use of spinal manipulation developed by osteopathy's founder, Andrew Taylor Still, Gevitz traces the movement's early success, despite attacks from the orthodox medical community, and details the internal struggles to broaden osteopathy's scope to include the full range of pharmaceuticals and surgery. He also recounts the efforts of osteopathic colleges to achieve parity with institutions granting M.D. degrees and looks at the continuing effort by osteopathic physicians and surgeons to achieve greater recognition and visibility.In print continuously since 1982, The DOs has now been thoroughly updated and expanded to include two new chapters addressing recent and current challenges and to bring the history of the profession up to the beginning of the new millennium.

    Those who believe that myths are something that exist only in the far distant path are incorrect. Anyone who knows a little bit about modern river monsters knows they are the root of 20th and even 21st century cryptozoology myths. For children, reading about these amazing creatures, both ones we know exist and those that are pure fantasy, opens many doors of imagination. The sense of wonder gained helps the young ones to think more broadly about the world.

    joins Ford Motor Co. in 1948, he has no idea the part he'll play in automotive history. Morsey's arrival comes as Henry Ford II and other titans in the industry are about to kill the vaunted V-8 engine. He sees it as his sole mission to talk them out of it. In The Man Who Saved the V-8, he shares the never-before-told story of how his crusade saved the engine that would go on to power iconic cars like the Ford Thunderbird and Mustang. "To this day, I have no idea how a young, newly hired manager like myself...had the nerve to challenge the most powerful men inside Ford Motor Company and tell them they were wrong," Morsey says. "But that is exactly what I did." The twenty-nine-year-old executive embarks on massive market research. He works with manufacturing experts to find ways to produce the V-8 engine more efficiently. After finding success, he goes on to continue playing a central role in some of the most pivotal decisions that would ensure Ford remains one of the powerhouses in the automotive industry. The Man Who Saved the V-8 tells the story of his successes and lessons learned.
