C. Cole. Once again, acclaimed science writer K. C. Cole brings the arcane and academic down to the level of armchair scientists in The Hole in the Universe, an entertaining and edifying search for nothing at all. Open the newspaper on any given day and you will read of a newly discovered planet, star, and so on. Yet scientists and mathematicians have spent generations searching the far reaches of the universe for that one elusive state—nothingness. Although this may sound like a simple task, every time the absolute void appears within reach, something new is discovered in its place: a black hole, an undulating string, an additional dimension of space or time—even another universe. A fascinating and literary tour de force, The Hole in the Universe is a virtual romp into the unknown that you never knew wasn't there.

    Large format diagrams show these objects exactly as they appear in a small telescope and for each object there is information on the current state of our astronomical knowledge. Revised and updated, this new edition contains a chapter with ten new spreads describing spectacular deep sky objects visible from the southern hemisphere, and tips on observing the upcoming transits of Venus. It also discusses Dobsonian telescopes, with hints on using personal computers and the Internet as aids for planning an observing session. Also new to this edition are redrawn Guidepost figures at the beginning of each season chapter that allow readers to visualize a three-dimensional view of the sky's dome; redesigned seasonal object layouts that provide more space for the naked-eye charts; a new spread on double stars near Bo�tes has been added to Spring, replacing the Shrinking Double spread; and a unique When and Where to Look table has been added to the last page, among other new features. Unlike many guides to the night sky, this book is specifically written for observers using small telescopes. Clear and easy to use, this fascinating book will appeal to skywatchers of all ages and backgrounds. No previous knowledge of astronomy is needed.

Davidson thoroughly explores Sagan's science, wrestles with his politics, and plumbs his personal passions with a telling instinct for the revealing underside of a life lived so publicly." -Los Angeles TimesCarl Sagan was one of the most celebrated scientists of this century-the handsome and alluring visionary who inspired a generation to look to the heavens and beyond. His life was both an intellectual feast and an emotional rollercoaster. Based on interviews with Sagan's family and friends, including his widow, Ann Druyan; his first wife, acclaimed scientist Lynn Margulis; and his three sons, as well as exclusive access to many personal papers, this highly acclaimed life story offers remarkable insight into one of the most influential, provocative, and beloved figures of our time-a complex, contradictory prophet of the Space Age.

    G. Wells' 1895 classic The Time Machine, readers of science fiction have puzzled over the paradoxes of time travel. What would happen if a time traveler tried to change history? Would some force or law of nature prevent him? Or would his action produce a "new" history, branching away from the original?In the last decade of the twentieth century a group of theoretical physicists at the California Institute of Technology undertook a serious investigation of the possibility of pastward time travel, inspiring a serious and sustained study that engaged more than thirty physicists working at universities and institutes around the world.Many of the figures involved are familiar: Einstein, Stephen Hawking and Kip Thorne; others are names known mostly to physicists. These are the new time travelers, and this is the story of their work--a profoundly human endeavor marked by advances, retreats, and no small share of surprises. It is a fantastic journey to the frontiers of physics.

    CONGRATULATIONS TO HERBERT KROEMER, 2000 NOBEL LAUREATE FOR PHYSICS For upper-division courses in thermodynamics or statistical mechanics, Kittel and Kroemer offers a modern approach to thermal physics that is based on the idea that all physical systems can be described in terms of their discrete quantum states, rather than drawing on 19th-century classical mechanics concepts.

    Ada's life spanned the years 1815 to 1852, during which the newly introduced rail lines and telegraph access made the power of technology a reality in people's lives. The Romantic movement was the backlash against those who would attempt to apply "scientific" thinking to every aspect of the human experience. As one of the Romantic movement's greatest prophets, Lord Byron's excessive indulgence of various illicit desires (one being particularly dangerous) led him to marry a woman who deluded herself into believing she could save him. Ada's mother, Annabella, was the dominant force in her life -- a self-righteous and self-serving woman who embraced the new virtues of rationality.The marriage lasted barely long enough for Annabella to become pregnant, and she spent the rest of her life justifying the infamous separation from her celebrity husband. Annabella barred Byron from any contact with his daughter and put Ada on a strict regimen of moral and mathematical study to suppress any Byronic tendencies Ada may have inherited. To the public eye, Ada was a curiosity. Put upon in an entirely modern way, Ada was famous from the day she was born. Although Ada took up science with enthusiasm, her Byronic eccentricities and passions were not extinguished by logic. Like her father, Ada looked to marriage to save her, but her husband, the future Earl of Lovelace, was not able to control her in the end. As an adult, Ada set out to find her mission, which she hoped would combine her two halves, and prove that the product of science and poetry would produce genius, not a monstrosity. Her work with Babbage was one attempt at a "poetical science" requiring imagination and rigor. She also indulged in many of the other popular ideas of the day, such as phrenology and mesmerism, with a more discerning eye than most. At the end of her life, she turned to the new work being done with that mysterious force, electricity, in the hopes of finding a molecular basis in the human nervous system to explain emotions. She was plagued by this time with both physical and mental disorders, and so also hoped to find some personal salvation in this quest. But her Byronic nature was getting stronger in the form of an affair and gambling addiction (there is an interesting speculation that she tried to develop a mathematical formula to beat the odds), and she finally succumbed to illness. In the end she requested to be buried next to the father she never knew in life. The Bride of Science is a wonderful portrait of the struggle between reason and passion. --Laura Wood, Science & Nature Editor

    Douglas Adams was a science and technology enthusiast and his books were inspired by--and sometimes, prefigured--many of the great scientific debates of our time. The Science of The Hitchhiker's Guide to the Galaxy is a lighthearted, accessible and informative tour of the real cutting-edge research behind this much-loved classic, including space tourism, parallel universes, instant translation devices, sentient computers, and more.

    The book is intended to be used in a one-semester course covering modern physics for students who have already had basic physics and calculus courses. The balance of the book leans more toward ideas than toward experimental methods and practical applications because the beginning student is better served by a conceptual framework than by a mass of details. The sequence of topics follows a logical, rather than strictly historical, order. Relativity and quantum ideas are considered first to provide a framework for understanding the physics of atoms and nuclei. The theory of the atom is then developed, and followed by a discussion of the properties of aggregates of atoms, which includes a look at statistical mechanics. Finally atomic nuclei and elementary particles are examined.
