Having just completed his masterpiece, The General Theory of Relativity—which provided a brand-new theory of gravity and promised a new perspective on the cosmos as a whole—he set out at once to share his excitement with as wide a public as possible in this popular and accessible book.Here published for the first time as a Penguin Classic, this edition of Relativity features a new introduction by bestselling science author Nigel Calder.

    Astrophysicist Adam Frank traces the question of alien life and intelligence from the ancient Greeks to the leading thinkers of our own time, and shows how we as a civilization can only hope to survive climate change if we recognize what science has recently discovered: that we are just one of ten billion trillion planets in the Universe, and it’s highly likely that many of those planets hosted technologically advanced alien civilizations. What’s more, each of those civilizations must have faced the same challenge of civilization-driven climate change.Written with great clarity and conviction, Light of the Stars builds on the inspiring work of pioneering scientists such as Frank Drake and Carl Sagan, whose work at the dawn of the space age began building the new science of astrobiology; Jack James, the Texas-born engineer who drove NASA’s first planetary missions to success; Vladimir Vernadsky, the Russian geochemist who first envisioned the Earth’s biosphere; and James Lovelock and Lynn Margulis, who invented Gaia theory. Frank recounts the perilous journey NASA undertook across millions of miles of deep space to get its probes to Venus and Mars, yielding our first view of the cosmic laws of planets and climate that changed our understanding of our place in the universe.Thrilling science at the grandest of scales, Light of the Stars explores what may be the largest question of all: What can the likely presence of life on other worlds tell us about our own fate?

    Indeed, no other legislature in the world approaches its power. Yet most Americans have only a murky idea of how it works. In The U.S. Congress, Donald A. Ritchie, a congressional historian for more than thirty years, takes readers on a fascinating, behind-the-scenes tour of Capitol Hill--pointing out the key players, explaining their behavior, and translating parliamentary language into plain English. No mere civics lesson, this eye-opening book provides an insiders perspective on Congress, matched with a professional historians analytical insight. After a swift survey of the creation of Congress by the constitutional convention, he begins to unscrew the nuts and pull out the bolts. What is it like to campaign for congress? To attract large donors? To enter either house with no seniority? He answers these questions and more, explaining committee assignments (and committee work), the role of staffers and lobbyists, floor proceedings, parliamentary rules, and coalition building. Ritchie explores the great effort put into constituent service--as representatives and senators respond to requests from groups and individuals--as well as media relations and news coverage. He also explores how the grand concepts we all know from civics class--checks and balances, advise and consent, congressional oversight--work in practice, in an age of strong presidents and a muscular Senate minority (no matter which party is in that position). In this sparkling addition to Oxfords Very Short Introduction series, Donald Ritchie moves beyond the cynicism and the platitudes to provide a gem of a portrait of how Congress really works.

    The term has become something of a catch-all, a convenient way to encompass numerous issues and developments which pertain to the political, social, and economic history of modern Ireland. It is a question which refuses to go away, but it is also a question whose inconstant meaning is rarely anatomized and still less often denied. One of the main aims of this book is to explore the complicated and shifting nature of the Irish Question, and to assess what it has meant to various political minds and agendas. The book is arranged both thematically and chronologically; each of the eight chapters takes as its focus a particular period, and each period is discussed within the context of one or more questions which informed and shaped that particular period.About the Series: Combining authority with wit, accessibility, and style, Very Short Introductions offer an introduction to some of life's most interesting topics. Written by experts for the newcomer, they demonstrate the finest contemporary thinking about the central problems and issues in hundreds of key topics, from philosophy to Freud, quantum theory to Islam

    Indeed, many physicists today believe that there are other dimensions beyond the four of our space-time, and that a unified vision of the various forces of nature can be achieved, if we consider that everything we see around us, from the trees to the stars are nothing but vibrations in hyperspace. Hyperspace theory - and its more recent derivation, superstring theory - is the eye of this revolution. In this book, Michio Kaku shows us a fascinating panorama, which completely changes our view of the cosmos, and takes us on a dazzling journey through new dimensions: wormholes connecting parallel universes, time machines, "baby universes" and more. Similar wonders are emerging in some pages in which everything is explained with elegant simplicity and where the mathematical formulation is replaced by imaginative illustrations that allow the problems to be visualized. The result is a very entertaining and surprising book, which even leaves behind the greatest fantasies of the old science fiction authors.
