All life as we know it is carbon-based, reliant on sources of liquid water and energy for its survival, and as far as we are aware, exists only on Earth.Our planet occupies a unique spot in the solar system. It is just the right distance from the Sun--within the so-called Goldilocks Zone--to be not too hot or too cold for liquid water to be stable on its surface, which, together with a protective shielding atmosphere, allowed the four-billion-year journey from a single-celled organism to an upright humanoid species. Most of primordial life, if seen today, would be classified as “alien,” as it bears little resemblance to anything that currently exists.We can learn much about the possibilities of extraterrestrial life by studying life forms from our planet's history and by exploring organisms still present in harsh environments on Earth that mimic those on other worlds. These organisms, called “extremophiles,” are directing our search for alien life throughout the solar system and beyond. Could we one day find Earth's toughest animal, the microscopic water bear, living under the surface of another world? Goldilocks and the Water Bears is an accessible introduction to the most fascinating of all the astro-sciences--the quest to learn whether we are alone in the universe.

    Throughout the book there are glimpses of long lost childhood summers, his grandparents, adolescence and, most importantly, his writing. The book, which is near to autobiographical of Levi's post-Auschwitz years, conveys his conviction that though "we are living in an epoch rife with problems and perils, it is not boring".

    He was usually credited as Camille Flammarion. He was a prolific author of more than fifty titles, including popular science works about astronomy, several notable early science fiction novels, and several works about Spiritualism and related topics. He also published the magazine L'Astronomie, starting in 1882. He maintained a private observatory at Juvisy-sur-Orge, France. He was a founder and the first president of the Socit Astronomique de France, which originally had its own independent journal, BSAF (Bulletin de la Socit Astronomique de France), first published in 1887. He was the first to suggest the names Triton and Amalthea for moons of Neptune and Jupiter, respectively, although these names were not officially adopted until many decades later. His spiritualism studies influenced also some of his science fiction. Other than that his writing about other worlds adhered fairly closely to then current ideas in evolutionary theory and astronomy. Amongst his other works are: The Atmosphere (1873), Popular Astronomy (1907), Astronomy for Amateurs (1904), Omega: The Last Days of the World and Death and its Mystery.

    As huge as the Pantheon of Rome and as heavy as the Statue of Liberty, this magnificent instrument is so precisely built that its seventeen-foot mirror was hand-polished to a tolerance of 2/1,000,000 of an inch. The telescope's construction drove some to the brink of madness, made others fearful that mortals might glimpse heaven, and transfixed an entire nation. Ronald Florence weaves into his account of the creation of "the perfect machine" a stirring chronicle of the birth of Big Science and a poignant rendering of an America mired in the depression yet reaching for the stars.

    Peter H. Duesberg argues that HIV is merely a harmless passenger virus that does not cause AIDS. Sure to spark intense debate, this provocative book offers an original and incisive critique of the rise and fall of HIV.

    Written by one of the world's leading experimental cosmologists, this short but deeply insightful book describes what scientists are revealing through precise measurements of the faint thermal afterglow of the Big Bang--known as the cosmic microwave background, or CMB--and how their findings are transforming our view of the cosmos.Blending the latest findings in cosmology with essential concepts from physics, Lyman Page first helps readers to grasp the sheer enormity of the universe, explaining how to understand the history of its formation and evolution in space and time. Then he sheds light on how spatial variations in the CMB formed, how they reveal the age, size, and geometry of the universe, and how they offer a blueprint for the formation of cosmic structure.Not only does Page explain current observations and measurements, he describes how they can be woven together into a unified picture to form the Standard Model of Cosmology. Yet much remains unknown, and this incisive book also describes the search for ever deeper knowledge at the field's frontiers--from quests to understand the nature of neutrinos and dark energy to investigations into the physics of the very early universe.

    So what is this particle called the Higgs boson? Why does it matter so much? What does this "God particle" tells us about the Universe? And was finding it really worth all the effort? The short answer is yes, and there was much at stake: our basic model for the building blocks of the Universe, the Standard Model, would have been in tatters if there was no Higgs particle. The Higgs field had been proposed as the way in which particles gain mass - a fundamental property of matter. Little wonder the hunt and discovery have produced such intense media interest. Here, Jim Baggott explains the science behind the discovery, looking at how the concept of a Higgs field was invented, how it is part of the Standard Model, and its implications on our understanding of all mass in the Universe.

    2600-2400 b.c.) were vast astronomically sophisticated temples, rather than the pharaonic tombs depicted by conventional Egyptology. In March 1993, a tiny remote-controlled robot created by Rudolf Gantenbrink, a German robotics engineer, traveled up airshafts within the Great Pyramid of Giza and relayed to scientists video pictures of a hitherto unknown sealed door within the pyramid. Bauval, a British engineer and writer who has been investigating the pyramids for more than ten years, and Gilbert, a British publishing consultant, use Gantenbrink's tantalizing discovery as a launching pad for an extended analysis of the purpose of the mysterious airshafts, which lead from the Great Pyramid's chambers to its exterior, and of the placement of other Fourth Dynasty pyramids. They were sited, the authors argue, to coincide with the key stars of Orion, a constellation that had religious significance for the Egyptians. Bauval and Gilbert claim that the shafts were pointed directly at important stars in Orion--that is, at those stars as they were placed in ancient times. Using astronomical data about stellar movement, they argue that the Orion stars coincide exactly with the pyramids' positions in approximately 10,400 b.c.--a period the Egyptians called the First Time, when they believed the god Osiris ruled the Earth. The authors also speculate that the mysterious space within the Great Pyramid discovered by Gantenbrink contains the mythical Benben stone, which the Egyptians linked to the creation of the world. The book's contentions are sometimes far-fetched and certainly unlikely to put scholarly controversy about the pyramids to rest. Still, this is an enjoyably radical rethinking of the mystery of the pyramids, with some ingenious arguments made in lucid style.A revolutionary book that explains the most enigmatic and fascinating wonder of the ancient world: the Pyramids of Egypt. "[An] absorbing and fascinating work of archaeological detection...clearly and rivetingly told...the book is highly and compulsively readable."--London Sunday Times. 16-page black-and-white inserts.

    You can’t fathom the weirdness– unless you’re one of the ER aliens. If you are, buy a dozen copies to give away: to your family, your neighbors, and the PTA. They’ll learn things you never had the heart to tell them, but they should know, like how it's like to work in the ER, the deviousness of shampoo bottles and the dangers of frying bacon naked.

    nd its place within a grander scheme, one of the most creative and original of contemporary scientists draws together recent advances in astrophysics and up-to-the-minute research to cast a piercing light on man's place in the cosmos.

    From its inception, Margaret Wertheim shows, physics has been an overwhelmingly male-dominated activity; she argues that gender inequity in physics is a result of the religious origins of the enterprise.Pythagoras' Trousers is a highly original history of one of science's most powerful disciplines. It is also a passionate argument for the need to involve both women and men in the process of shaping the technologies from the next generation of physicists.
