#1 NEW YORK TIMES BESTSELLERA landmark volume in science writing by one of the great minds of our time, Stephen Hawking's book explores such profound questions as: How did the universe begin--and what made its start possible? Does time always flow forward? Is the universe unending--or are there boundaries? Are there other dimensions in space? What will happen when it all ends? Told in language we all can understand, A Brief History of Time plunges into the exotic realms of black holes and quarks, of antimatter and "arrows of time," of the big bang and a bigger God--where the possibilities are wondrous and unexpected. With exciting images and profound imagination, Stephen Hawking brings us closer to the ultimate secrets at the very heart of creation.
In 1977, Feynman and his sidekick— fellow drummer and geography enthusiast Ralph Leighton—set out to make arrangements to visit Tuva, doing noble and hilarious battle with Soviet red tape, befriending quite a few Tuvans, and discovering the wonders of Tuvan throat-singing. Their Byzantine attempts to reach Tannu Tuva would span a decade, interrupted by Feynman's appointment to the committee investigating the Challenger disaster, and his tragic struggle with the cancer that finally killed him. Tuva or Bust! chronicles the deepening friendship of two zany, brilliant strategists whose love of the absurd will delight and instruct. It is Richard Feynman's last, best adventure.
From the author of Astrophysics for People in a Hurry and the host of Cosmos: A Spacetime Odyssey, a memoir about growing up and a young man's budding scientific curiosity. This is the absorbing story of Neil deGrasse Tyson's lifelong fascination with the night sky, a restless wonder that began some thirty years ago on the roof of his Bronx apartment building and eventually led him to become the director of the Hayden Planetarium. A unique chronicle of a young man who at one time was both nerd and jock, Tyson's memoir could well inspire other similarly curious youngsters to pursue their dreams. Like many athletic kids he played baseball, won medals in track and swimming, and was captain of his high school wrestling team. But at the same time he was setting up a telescope on winter nights, taking an advanced astronomy course at the Hayden Planetarium, and spending a summer vacation at an astronomy camp in the Mojave Desert. Eventually, his scientific curiosity prevailed, and he went on to graduate in physics from Harvard and to earn a Ph.D. in astrophysics from Columbia. There followed postdoctoral research at Princeton. In 1996, he became the director of the Hayden Planetarium, where some twenty-five years earlier he had been awed by the spectacular vista in the sky theater. Tyson pays tribute to the key teachers and mentors who recognized his precocious interests and abilities, and helped him succeed. He intersperses personal reminiscences with thoughts on scientific literacy, careful science vs. media hype, the possibility that a meteor could someday hit the Earth, dealing with society's racial stereotypes, what science can and cannot say about the existence of God, and many other interesting insights about science, society, and the nature of the universe. Now available in paperback with a new preface and other additions, this engaging memoir will enlighten and inspire an appreciation of astronomy and the wonders of our universe.
Chaos surrounds us. Seemingly random events -- the flapping of a flag, a storm-driven wave striking the shore, a pinball's path -- often appear to have no order, no rational pattern. Explicating the theory of chaos and the consequences of its principal findings -- that actual, precise rules may govern such apparently random behavior -- has been a major part of the work of Edward N. Lorenz. In The Essence of Chaos, Lorenz presents to the general reader the features of this "new science," with its far-reaching implications for much of modern life, from weather prediction to philosophy, and he describes its considerable impact on emerging scientific fields.
Unlike the phenomena dealt with in relativity theory and quantum mechanics, systems that are now described as "chaotic" can be observed without telescopes or microscopes. They range from the simplest happenings, such as the falling of a leaf, to the most complex processes, like the fluctuations of climate. Each process that qualifies, however, has certain quantifiable characteristics: how it unfolds depends very sensitively upon its present state, so that, even though it is not random, it seems to be. Lorenz uses examples from everyday life, and simple calculations, to show how the essential nature of chaotic systems can be understood. In order to expedite this task, he has constructed a mathematical model of a board sliding down a ski slope as his primary illustrative example. With this model as his base, he explains various chaotic phenomena, including some associated concepts such as strange attractors and bifurcations.
As a meteorologist, Lorenz initially became interested in the field of chaos because of its implications for weather forecasting. In a chapter ranging through the history of weather prediction and meteorology to a brief picture of our current understanding of climate, he introduces many of the researchers who conceived the experiments and theories, and he describes his own initial encounter with chaos.
A further discussion invites readers to make their own chaos. Still others debate the nature of randomness and its relationship to chaotic systems, and describe three related fields of scientific thought: nonlinearity, complexity, and fractality. Appendixes present the first publication of Lorenz's seminal paper "Does the Flap of a Butterfly's Wing in Brazil Set Off a Tornado in Texas?"; the mathematical equations from which the copious illustrations were derived; and a glossary.
Interviews with Hawking, his family, colleagues, and friends provide a close-up look at one of the world's greatest physicists, as well as a lucid explanation of his major theories
Richard Feynman, winner of the Nobel Prize in physics, thrived on outrageous adventures. Here he recounts in his inimitable voice his experience trading ideas on atomic physics with Einstein and Bohr and ideas on gambling with Nick the Greek; cracking the uncrackable safes guarding the most deeply held nuclear secrets; accompanying a ballet on his bongo drums; painting a naked female toreador. In short, here is Feynman's life in all its eccentric--a combustible mixture of high intelligence, unlimited curiosity, and raging chutzpah.
To his colleagues, Richard Feynman was not so much a genius as he was a full-blown magician: someone who "does things that nobody else could do and that seem completely unexpected." The path he cleared for twentieth-century physics led from the making of the atomic bomb to a Nobel Prize-winning theory of quantam electrodynamics to his devastating expos of the Challenger space shuttle disaster. At the same time, the ebullient Feynman established a reputation as an eccentric showman, a master safe cracker and bongo player, and a wizard of seduction.Now James Gleick, author of the bestselling Chaos, unravels teh dense skein of Feynman's thought as well as the paradoxes of his character in a biography--which was nominated for a National Book Award--of outstanding lucidity and compassion.
If you think a negative charge is something that shows up on your credit card bill -- if you imagine that Ohm's Law dictates how long to meditate -- if you believe that Newtonian mechanics will fix your car -- you need The Cartoon Guide to Physics to set you straight.You don't have to be a scientist to grasp these and many other complex ideas, because The Cartoon Guide to Physics explains them all: velocity, acceleration, explosions, electricity and magnetism, circuits -- even a taste of relativity theory -- and much more, in simple, clear, and, yes, funny illustrations. Physics will never be the same
