    It would be 19 years before another woman got a chance—cosmonaut Svetlana Savitskaya in 1982—followed by American astronaut Sally Ride a year later. By breaking the stratospheric ceiling, these women forged a path for many female astronauts, cosmonauts, and mission specialists to follow.            Women in Space profiles 23 pioneers, including Eileen Collins, the first woman to command the space shuttle; Peggy Whitson, who logged more than a year in orbit aboard the International Space Station; and Mae Jemison, the first African American woman in space; as well as astronauts from Japan, Canada, Italy, South Korea, France, and more. Readers will also learn about the Mercury 13, American women selected by NASA in the late 1950s to train for spaceflight. Though they matched and sometimes surpassed their male counterparts in performance, they were ultimately denied the opportunity to head out to the launching pad. Their story, and the stories of the pilots, physicists, and doctors who followed them, demonstrate the vital role women have played in the quest for scientific understanding.

    A total eclipse of the Sun will be visible from within a narrow corridor that traverses the United States. The path of the Moon's umbral shadow will begin in the northern Pacific and cross the USA from west to east from Oregon to South Carolina. The Moon's penumbral shadow will produce a partial eclipse visible from most of North America. In fact, the 2017 full eclipse is such an important sky event that sky watchers in Europe are already planning trips to view it. 2017 Guide to the Night Sky provides all of the information needed to view this exciting eclipse and track its path. The time zones and transit of the eclipse will be noted inside the book's jacket for quick and easy reference.The night sky makes for exciting viewing any time of the year, and 2017 Guide to the Night Sky is the ideal guide to help amateur astronomers find their way for the entire 12 months. With monthly charts and other diagrams set for a latitude of 40 degrees North, it shows how the visible stars change from month to month and includes the many sky events that occur throughout the year. It is highly practical for beginning sky gazers because the objects and events may be observed with the naked eye, or nothing more complicated than a pair of binoculars.The month-by-month guides include sky activity charts and moon calendars; meteors (with dates of showers, including hourly rate of radiants); the Planets; ecliptic charts; diagrams of interesting events; plus sky and constellation maps throughout.An appendix includes a full glossary; the Greek Alphabet; the constellation genitives, abbreviations and English names; a table of common asterisms; further information; recommended astronomy journals, societies, institutions and organizations; software, and internet sources.Especially useful for beginning sky watchers, this guide will be fully updated to 2017. Its small and light format makes it the ideal portable reference for backyard astronomers.

    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.

    Her captivating inquiry into the most modern and daring of technologies spanning some 60 years — a mere speck in cosmic terms — takes the reader on a journey which captures the relics of space forays and uncovers the cultural value of detritus all too readily dismissed as junk.In this book, she takes a physical journey through the solar system and beyond, and a conceptual journey into human interactions with space. Her tools are artefacts, historical explorations, the occasional cocktail recipe, and the archaeologist’s eye applied not only to the past, but the present and future as well.Erudite and playful, Dr Space Junk reveals that space is not as empty as we might think. And that by looking up and studying space artefacts, we learn an awful lot about our own culture on earth. She makes us realise that objects from the past — the material culture produced by the Space Age and beyond — are so significant to us now because they remind us of what we might want to hold onto into the future.

    Along the way Stephen Baxter looks at our place in the universe, considers the possibility that we are in fact alone, and wonders whether that fact gives us the right to inherit everything. He also looks at how we might strive to overcome the limitations of the physical universe and win the deepest future. Stephen Baxter has brought his trademark narrative flair and imaginative brilliance to the latest ideas in physics and cosmology and produced a breathtaking guide to our possible futures.

    The solved exercises cover all of the techniques discussed in the text, and include step-by-step instruction on working through the algorithms.

    In addition to being the most up-to-date communications text available, Simon Haykin has added MATLAB computer experiments.

    The volume also contains a group of modern narratives, including the famous, and much-anthologized, Moonlight Sonata. Ritsos, rightly, regarded the The Fourth Dimension as his finest achievement. It is now presented to English- speaking readers for the first time in its entirety.From PhiloctetesAll the speeches of great men, about the dead and about heroes. Astonishing, awesome words, pursued us even in our sleep, slipping beneath closed doors, from the banqueting hallwhere glasses and voices sparkled, and the veilof an unseen dancer rippled silentlylike a diaphanous, whirling wallbetween life and death. This throbbingour childhood nights, lightening the shadows of shieldsetched on white walls by slow moonlight.

    The first NASA flight director, Kraft emerged from boyhood in small-town America to become a visionary who played an integral role in what would become the National Aeronautics and Space Administration. It's all here, from the legendary Mercury missions that first sent Americans into space through the Gemini and Apollo missions that landed them on the moon. The great heroes of space are here, too-Alan Shepard, John Glenn, Neil Armstrong, Jim Lovell, and Buzz Aldrin-leading the space race that would change the course of U.S. history. From NASA's infancy to its greatest triumphs . . . from the calculated gambles to the near disasters to the pure luck that accompanied each mission, Flight relives the spellbinding events that captured the imagination of the world. It is a stirring tribute to the U.S. space program and to the men who risked their lives to take America on a flight into the unknown-from the man who was there for it all. "A highly readable memoir." (The New York Times Book Review) "A rewarding look at the brief, shining moment when space pathfinders held sway over space warriors." (The Washington Post)

    Second, it proposes that the inhabitants of this subterranean biosphere are not plants or animals as we know them, but heat-loving bacteria that survive on a diet consisting solely of hydrocarbons that is, natural gas and petroleum. And third and perhaps most heretically, the book advances the stunning idea that most hydrocarbons on Earth are not the byproduct of biological debris ("fossil fuels"), but were a common constituent of the materials from which the earth itself was formed some 4.5 billion years ago.The implications are astounding. The theory proposes answers to often-asked questions: Is the deep hot biosphere where life originated, and do Mars and other seemingly barren planets contain deep biospheres? Even more provocatively, is it possible that there is an enormous store of hydrocarbons upwelling from deep within the earth that can provide us with abundant supplies of gas and petroleum?However far-fetched these ideas seem, they are supported by a growing body of evidence, and by the indisputable stature and seriousness Gold brings to any scientific debate. In this book we see a brilliant and boldly original thinker, increasingly a rarity in modern science, as he develops potentially revolutionary ideas about how our world works.

    Most people see the old constellations, the things they've been told to see. But Liberty sees new patterns, pictures, and possibilities. She's an exception. Some other exceptions:Her dad, who gave her the stars. Who moved out months ago and hasn't talked to her since.Her mom, who's happier since he left, even though everyone thinks she should be sad and lonely.And her sister, who won't go outside their house. Liberty feels like her whole world is falling from space. Can she map a new life for herself and her family before they spin too far out of reach?

    This edition features optional quantitative reasoning boxes, basic equations throughout the book, new end-of-chapter problems, and a consolidated math appendix for professors who want to emphasize quantitative understanding in their course. Key figures have been annotated to guide student interpretation of difficult concepts. New two-page Cosmic Context illustration spreads throughout the book, and at the end of every part, visually tie together key concepts from across chapters and put them in context, driving home main ideas in a meaningful way.
