Their work has uncovered a number of the universe’s more surprising secrets, and many believe further wonders remain hidden within the theory’s tangle of equations, waiting to be exposed. In this sweeping narrative of science and culture, astrophysicist Pedro Ferreira brings general relativity to life through the story of the brilliant physicists, mathematicians, and astronomers who have taken up its challenge. For these scientists, the theory has been both a treasure trove and an enigma, fueling a century of intellectual struggle and triumph.. Einstein’s theory, which explains the relationships among gravity, space, and time, is possibly the most perfect intellectual achievement of modern physics, yet studying it has always been a controversial endeavor. Relativists were the target of persecution in Hitler’s Germany, hounded in Stalin’s Russia, and disdained in 1950s America. Even today, PhD students are warned that specializing in general relativity will make them unemployable. Despite these pitfalls, general relativity has flourished, delivering key insights into our understanding of the origin of time and the evolution of all the stars and galaxies in the cosmos. Its adherents have revealed what lies at the farthest reaches of the universe, shed light on the smallest scales of existence, and explained how the fabric of reality emerges. Dark matter, dark energy, black holes, and string theory are all progeny of Einstein’s theory. We are in the midst of a momentous transformation in modern physics. As scientists look farther and more clearly into space than ever before, The Perfect Theory reveals the greater relevance of general relativity, showing us where it started, where it has led, and where it can still take us.

    We humans are perfectly designed for life on Earth. We can walk around, breathe, drink water, eat vegetables, read books, not get poisoned or crushed to death when we go outside - it's lovely right where we are.) Not convinced? GOOD! People have been dreaming about space travel for centuries - there's something amazing about the idea of leaving our planet behind and setting out to explore the Universe - there's so much we still don't know. UK and Ireland's best-loved comedian Dara O Briain takes you on a journey from the safety of your comfiest chair to the furthest reaches of space (and beyond!)

    No other telescope combines instant name recognition with the production of consistently spectacular images. Yet few people outside of the astronomy community realize that Hubble is now at the apex of its imaging capabilities. A collection of stunningly detailed pictures, made possible by the new Wide Field Camera 3, has yet to be incorporated into a popular-level book. Until now. Hubble's Universe will be the premier venue for the Hubble Telescope's most recent visual splendors. Bestselling astronomy writer Terence Dickinson showcases extraordinary late-breaking pictures, many of which have yet to receive wide distribution as news stories or in publications outside scientific papers, and presents a breathtaking portfolio drawn from an archive of over 500,000 existing Hubble images.The accompanying text balances accuracy with accessibility, Dickinson's hallmark. And thanks to the author's familiarity with Hubble's history and discoveries and his access to top Hubble scientists for insight and accuracy, the text includes facts and tidbits not found in any other book. Combined with hundreds of brilliant images, the clear, succinct and illuminating narrative brings to life the fascinating forces at work in the universe.

    Though he is still best known for this finding, his partnership with his sister Caroline yielded groundbreaking work, including techniques that remain in use today. The duo pioneered comprehensive surveys of the night sky, carefully categorizing every visible object in the void. Caroline wrote an influential catalogue of nebulae, and William discovered infrared radiation. Celebrated science writer Michael Lemonick guides readers through the depths of the solar system and into his protagonists' private lives: William developed bizarre theories about inhabitants of the sun; he procured an unheard-of salary for Caroline even while haggling with King George III over the funding for an enormous, forty-foot telescope; the siblings feuded over William's marriage and eventually reconciled. Erudite and accessible, The Georgian Star is a lively portrait of the pair who invented modern astronomy.

    Here he explains how our image of the world has changed throughout centuries. Fom Aristotle to Albert Einstein, Michael Faraday to the Higgs boson, he takes us on a wondrous journey to show us that beyond our ever-changing idea of reality is a whole new world that has yet to be discovered.

    But more than this, there was gravity. After that, all hell broke loose… In A Universe from Nothing, Krauss revealed how our entire universe could arise from nothing. Now, he reveals what that something—reality—is. And, reality is not what we think or sense—it’s weird, wild, and counterintuitive; it’s hidden beneath everyday experience; and its inner workings seem even stranger than the idea that something can come from nothing. In a landmark, unprecedented work of scientific history, Krauss leads us to the furthest reaches of space and time, to scales so small they are invisible to microscopes, to the birth and rebirth of light, and into the natural forces that govern our existence. His unique blend of rigorous research and engaging storytelling invites us into the lives and minds of the remarkable, creative scientists who have helped to unravel the unexpected fabric of reality—with reason rather than superstition and dogma. Krauss has himself been an active participant in this effort, and he knows many of them well. The Greatest Story challenges us to re-envision ourselves and our place within the universe, as it appears that “God” does play dice with the universe. In the incisive style of his scintillating essays for The New Yorker, Krauss celebrates the greatest intellectual adventure ever undertaken—to understand why we are here in a universe where fact is stranger than fiction.

    An accidental tea spill damages the royal papyrus she has been struggling to interpret, the papyrus purported to be Queen Tiye’s last message to her son, Tutankhamun. But the spill also exposes hidden writing below the surface hieroglyphs. Horrified at the damage but aching to read the entire secret text, Rika agrees to let visiting remote-sensing expert David Chamberlain smuggle the priceless document out of the museum and scan it with instruments on his aircraft. The results are stunning. They show Tiye, previously a footnote in history, to have been the power behind the thrones of her husband and sons, as well as the architect of a monotheistic religion unique in ancient Egypt. Riveted by these revelations, Rika and David devise a covert plan to locate Tiye’s tomb. But Major Hassam of the Egyptian Secret Police misreads their activities as a plot to overthrow the government and vows to stop them at all costs. Reared in revolution, Rika feels a spiritual bond with Tiye, an African commoner who revolutionized Egyptian society by introducing a religion that freed Egypt from the tyranny of the Amun priests. Rika’s quest to find Tiye’s tomb parallels the queen’s last journey up the Nile, three thousand years before, to be buried alive in a tomb like no other. In a league with Michael Crichton, Dan Brown, and Wilbur Smith, John Oehler has created a cinematic page-turner of explosive yet poetic brilliance. And readers who liked Lisbeth Salander in Stieg Larsson’s The Girl with the Dragon Tattoo, will love Rika. Papyrus was a semi-finalist in the 2009 Amazon Breakthrough Novel Award competition (top 1% of 10,000 entries) and garnered more than a hundred 5-star reviews.

    The rest is known as dark matter and dark energy, because their precise identities are unknown. "The Cosmic Cocktail" is the inside story of the epic quest to solve one of the most compelling enigmas of modern science--what is the universe made of?--told by one of today's foremost pioneers in the study of dark matter.Blending cutting-edge science with her own behind-the-scenes insights as a leading researcher in the field, acclaimed theoretical physicist Katherine Freese recounts the hunt for dark matter, from the discoveries of visionary scientists like Fritz Zwicky--the Swiss astronomer who coined the term "dark matter" in 1933--to the deluge of data today from underground laboratories, satellites in space, and the Large Hadron Collider. Theorists contend that dark matter consists of fundamental particles known as WIMPs, or weakly interacting massive particles. Billions of them pass through our bodies every second without us even realizing it, yet their gravitational pull is capable of whirling stars and gas at breakneck speeds around the centers of galaxies, and bending light from distant bright objects. Freese describes the larger-than-life characters and clashing personalities behind the race to identify these elusive particles.Many cosmologists believe we are on the verge of solving the mystery. "The Cosmic Cocktail" provides the foundation needed to fully fathom this epochal moment in humankind's quest to understand the universe.

    Christopher Potter’s narrative is as imaginative, ingenious, and elegantly concise as it is user-friendly.” — Sylvia Nasar, author of A Beautiful Mind“A personal, brilliant, and often amusing account . . . . An idiosyncratic, encyclopedic blitzkrieg of a book.” —The Boston Globe“The Verdict: Read.” — TimeChristopher Potter’s You Are Here is a lively and accessible biography of the universe—how it fits together and how we fit into it—in the style of science writers like Richard Dawkins, Bill Bryson, and Richard Feynman, as seen through the lens of today’s most cutting-edge scientific thinking.

    She draws on conversations with hundreds of the world's top scientists and on her own work as a Pulitzer Prize-winning writer for the New York Times to create a thoroughly entertaining guide to scientific literacy. Angier's gifts are on full display in The Canon, an ebullient celebration of science that stands to become a classic. The Canon is vital reading for anyone who wants to understand the great issues of our time -- from stem cells and bird flu to evolution and global warming. And it's for every parent who has ever panicked when a child asked how the earth was formed or what electricity is. Angier's sparkling prose and memorable metaphors bring the science to life, reigniting our own childhood delight in discovering how the world works. "Of course you should know about science," writes Angier, "for the same reason Dr. Seuss counsels his readers to sing with a Ying or play Ring the Gack: These things are fun and fun is good." The Canon is a joyride through the major scientific disciplines: physics, chemistry, biology, geology, and astronomy. Along the way, we learn what is actually happening when our ice cream melts or our coffee gets cold, what our liver cells do when we eat a caramel, why the horse is an example of evolution at work, and how we're all really made of stardust. It's Lewis Carroll meets Lewis Thomas -- a book that will enrapture, inspire, and enlighten.
