The Big Bang Cosmology is explored, looking at its observational successes in explaining the expansion of the Universe, the existence and properties of the cosmic microwave background, and the origin of light elements in the universe. Properties of the very early Universe are also covered, including the motivation for a rapid period of expansion known as cosmological inflation. The third edition brings this established undergraduate textbook up-to-date with the rapidly evolving observational situation. This fully revised edition of a bestseller takes an approach which is grounded in physics with a logical flow of chapters leading the reader from basic ideas of the expansion described by the Friedman equations to some of the more advanced ideas about the early universe. It also incorporates up-to-date results from the Planck mission, which imaged the anisotropies of the Cosmic Microwave Background radiation over the whole sky. The Advanced Topic sections present subjects with more detailed mathematical approaches to give greater depth to discussions. Student problems with hints for solving them and numerical answers are embedded in the chapters to facilitate the reader's understanding and learning. Cosmology is now part of the core in many degree programs. This current, clear and concise introductory text is relevant to a wide range of astronomy programs worldwide and is essential reading for undergraduates and Masters students, as well as anyone starting research in cosmology.

    The case would become one of the most famous in modern medicine—and a total failure. As Nature Made Him tells the extraordinary story of David Reimer, who, when finally informed of his medical history, made the decision to live as a male. A macabre tale of medical arrogance, it is first and foremost a human drama of one man's—and one family's—amazing survival in the face of terrible odds.

    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"

    Keying Einstein's crucial discoveries to the simple mental images that inspired them, Michio Kaku finds a revealing new way to discuss his ideas, and delivers an appealing and always accessible introduction to Einstein's work.

    Hazen writes of how the co-evolution of the geosphere and biosphere—of rocks and living matter—has shaped our planet into the only one of its kind in the Solar System, if not the entire cosmos.With an astrobiologist’s imagination, a historian’s perspective, and a naturalist’s passion for the ground beneath our feet, Hazen explains how changes on an atomic level translate into dramatic shifts in Earth’s makeup over its 4.567 billion year existence. He calls upon a flurry of recent discoveries to portray our planet’s many iterations in vivid detail. Through his theory of “co-evolution,” we learn how reactions between organic molecules and rock crystals may have generated Earth’s first organisms, which in turn are responsible for more than two-thirds of the mineral varieties on the planet.The Story of Earth is also the story of the pioneering men and women behind the sciences. Readers will meet black-market meteorite hawkers of the Sahara Desert, the gun-toting Feds who guarded the Apollo missions’ lunar dust, and the World War II Navy officer whose super-pressurized “bomb”—recycled from military hardware—first simulated the molten rock of Earth’s mantle. As a mentor to a new generation of scientists, Hazen introduces the intrepid young explorers whose dispatches from Earth’s harshest landscapes will revolutionize geology.

    Thrown into a profession of gallows humor and vivid characters (both living and very dead), Caitlin learned to navigate the secretive culture of those who care for the deceased.Smoke Gets in Your Eyes tells an unusual coming-of-age story full of bizarre encounters and unforgettable scenes. Caring for dead bodies of every color, shape, and affliction, Caitlin soon becomes an intrepid explorer in the world of the dead. She describes how she swept ashes from the machines (and sometimes onto her clothes) and reveals the strange history of cremation and undertaking, marveling at bizarre and wonderful funeral practices from different cultures.Her eye-opening, candid, and often hilarious story is like going on a journey with your bravest friend to the cemetery at midnight. She demystifies death, leading us behind the black curtain of her unique profession. And she answers questions you didn’t know you had: Can you catch a disease from a corpse? How many dead bodies can you fit in a Dodge van? What exactly does a flaming skull look like?Honest and heartfelt, self-deprecating and ironic, Caitlin's engaging style makes this otherwise taboo topic both approachable and engrossing. Now a licensed mortician with an alternative funeral practice, Caitlin argues that our fear of dying warps our culture and society, and she calls for better ways of dealing with death (and our dead).

    How many of us understand the way seizures affect the brain, how the heart is connected to wellbeing, or the why the foot carries the key to our humanity?

    The pages take the reader on a wild narrative ride through the world of squid science and adventure, along the way addressing some riddles about what intelligence is, and what monsters lie in the deep. In addition to squid, both giant and otherwise, Kraken examines other equally enthralling cephalopods, including the octopus and the cuttlefish, and explores their otherworldly abilities, such as camouflage and bioluminescence. Accessible and entertaining, Kraken is also the first substantial volume on the subject in more than a decade and a must for fans of popular science.

    

    There were bacteria in volcanic hydrothermal vents on the ocean floor, single-celled algae in Antarctic ice floes, and fungi in the cooling pools of nuclear reactors.But might there be life stranger than the most extreme extremophile? Might there be, somewhere, another kind of life entirely? In fact, scientists have hypothesized life that uses ammonia instead of water, life based not in carbon but in silicon, life driven by nuclear chemistry, and life whose very atoms are unlike those in life we know. In recent years some scientists have begun to look for the tamer versions of such life on rock surfaces in the American Southwest, in a “shadow biosphere” that might impinge on the known biosphere, and even deep within human tissue. They have also hypothesized more radical versions that might survive in Martian permafrost, in the cold ethylene lakes on Saturn’s moon Titan, and in the hydrogen-rich atmospheres of giant planets in other solar systems. And they have imagined it in places off those worlds: the exotic ices in comets, the vast spaces between the stars, and—strangest of all—parallel universes.Distilling complex science in clear and lively prose, David Toomey illuminates the research of the biological avant-garde and describes the workings of weird organisms in riveting detail. His chapters feature an unforgettable cast of brilliant scientists and cover everything from problems with our definitions of life to the possibility of intelligent weird life. With wit and understanding that will delight scientists and lay readers alike, Toomey reveals how our current knowledge of life forms may account for only a tiny fraction of what’s really out there.

    "A stunning memoir from the astronaut who spent a record-breaking year aboard the International Space Station – a candid account of his remarkable voyage, the journeys that preceded it, and his colorful formative years." Inside book cover comments.

    An ancient curse. A stunning medical mystery. And a pioneering journey into the unknown heart of the world's densest jungle.Since the days of conquistador Hernán Cortés, rumors have circulated about a lost city of immense wealth hidden somewhere in the Honduran interior, called the White City or the Lost City of the Monkey God. Indigenous tribes speak of ancestors who fled there to escape the Spanish invaders, and they warn that anyone who enters this sacred city will fall ill and die. In 1940, swashbuckling journalist Theodore Morde returned from the rainforest with hundreds of artifacts and an electrifying story of having found the Lost City of the Monkey God-but then committed suicide without revealing its location.Three quarters of a century later, author Doug Preston joined a team of scientists on a groundbreaking new quest. In 2012 he climbed aboard a rickety, single-engine plane carrying the machine that would change everything: lidar, a highly advanced, classified technology that could map the terrain under the densest rainforest canopy. In an unexplored valley ringed by steep mountains, that flight revealed the unmistakable image of a sprawling metropolis, tantalizing evidence of not just an undiscovered city but an enigmatic, lost civilization.Venturing into this raw, treacherous, but breathtakingly beautiful wilderness to confirm the discovery, Preston and the team battled torrential rains, quickmud, disease-carrying insects, jaguars, and deadly snakes. But it wasn't until they returned that tragedy struck: Preston and others found they had contracted in the ruins a horrifying, sometimes lethal-and incurable-disease.

    --Washington RoeblingHis father conceived of the Brooklyn Bridge, but after John Roebling's sudden death, Washington Roebling built what has become one of American's most iconic structures--as much a part of New York as the Statue of Liberty or the Empire State Building. Yet, as recognizable as the bridge is, its builder is too often forgotten--and his life is of interest far beyond his chosen field. It is the story of immigrants, of the frontier, of the greatest crisis in American history, and of the making of the modern world.Forty years after the publication of The Great Bridge, David McCullough's classic chronicle of how the East River was spanned, Erica Wagner has written a fascinating biography of one of America's most distinguished engineers, a man whose long life was a model of courage in the face of extraordinary adversity. Chief Engineer is enriched by Roebling's own eloquent voice, unveiled in his recently-discovered memoir that was previously thought lost to history.The memoir reveals that his father, John-a renowned engineer who made his life in America after humble beginnings in Germany-was a tyrannical presence in Washington's life, so his own adoption of that career was hard won. A young man when the Civil War broke out, Washington joined the Union Army, building bridges that carried soldiers across rivers and seeing action in many pivotal battles, from Antietam to Gettysburg-aspects of his life never before fully brought to light. Safely returned, he married the remarkable Emily Warren Roebling, who would play a crucial role in the construction of the unprecedented Brooklyn Bridge. It would be Washington Roebling's grandest achievement-but by no means the only one.Elegantly written with a compelling narrative sweep, Chief Engineer will introduce Washington Roebling and his era to a new generation of readers.

    Their tools in this hunt are both fossils and cutting-edge genetic technologies. Some of these scientists are driven by sheer curiosity; others view the lost species as a powerful weapon in the fight to preserve rapidly changing ecosystems. It seems certain that these animals will walk the earth again, but what world will that give us? And is any of this a good idea? Science journalist Torill Kornfeldt travelled the world to meet the men and women working to bring these animals back from the dead. Along the way, she has seen the mammoth that has been frozen for 20,000 years, and visited the places where these furry giants will live again.
