Recent books have raised the public consciousness about the dangers of global warming and climate change. This book is intended to convey the message that there is a solution. The solution is the rapid development of hydrogen fusion energy. This energy source is inexhaustible and, although achieving fusion energy is difficult, the progress made in the past two decades has been remarkable. The physics issues are now understood well enough that serious engineering can begin.The book starts with a summary of climate change and energy sources, trying to give a concise, clear, impartial picture of the facts, separate from conjecture and sensationalism. Controlled fusion -- the difficult problems and ingenious solutions -- is then explained using many new concepts.The bottom line -- what has yet to be done, how long it will take, and how much it will cost -- may surprise you. Francis F. Chen's career in plasma has extended over five decades. His textbook Introduction to Plasma Physics has been used worldwide continuously since 1974. He is the only physicist who has published significantly in both experiment and theory and on both magnetic fusion and laser fusion. As an outdoorsman and runner, he is deeply concerned about the environment. Currently he enjoys bird photography and is a member of the Audubon Society.

How physicists are trying to solve our energy problems—by unlocking the secrets of the sun: “Explain[s] cutting-edge science with remarkable lucidity.” —Booklist This revelatory book tells the story of the scientists who believe the solution to the planet’s ills can be found in the original energy source: the Sun itself. There, at its center, the fusion of 620 million tons of hydrogen every second generates an unfathomable amount of energy. By replicating even a tiny piece of the Sun’s power on Earth, we can secure all the heat and energy we would ever need. The simple yet extraordinary ambition of nuclear-fusion scientists has garnered many skeptics, but, as A Piece of the Sun makes clear, large-scale nuclear fusion is scientifically possible—and perhaps even preferable to other options. Clery argues passionately and eloquently that the only thing keeping us from harnessing this cheap, clean and renewable energy is our own shortsightedness. “Surprisingly sprightly…Clery walks readers through the history of fusion study, from Lord Kelvin, Albert Einstein and a large cast of peculiar physicists, to all manner of international politics—e.g., the darts and feints of the Cold War, the braces applied by OPEC in the wake of the 1973 war among Israel, Egypt and Syria. Clery negotiates the hard science with aplomb.” —Kirkus Reviews “A timely perspective on truly urgent science.” —Booklist “Ultimately, Clery argues that developing a source of energy that won’t damage the climate—or ever run out—is worth striving for.” —Publishers Weekly

Originally published in 1990. This study was first written in 1965 when interest in Leibniz was intensifying. The book looks in detail at the doctrine of necessity – that necessary truths are those derivable from the principle of identity by the substitution of definitions. It first considers views of philosophic predecessors, relating Leibniz’ doctrine to Aristotle and Hobbes among others. The second section examines the conflict between his reductionistic and formalistic views and the opposing intuitionism and anti-reductionism of Descartes and Locke. The author critically examines the theory of necessity, including Leibniz’s arguments against the views of Hobbes and Locke, concluding with distinctions between necessary and contingent truths.

A comprehensive account of how energy has shaped society throughout history, from pre-agricultural foraging societies through today's fossil fuel–driven civilization. "I wait for new Smil books the way some people wait for the next 'Star Wars' movie. In his latest book, Energy and Civilization: A History, he goes deep and broad to explain how innovations in humans' ability to turn energy into heat, light, and motion have been a driving force behind our cultural and economic progress over the past 10,000 years. —Bill Gates, Gates Notes, Best Books of the Year Energy is the only universal currency; it is necessary for getting anything done. The conversion of energy on Earth ranges from terra-forming forces of plate tectonics to cumulative erosive effects of raindrops. Life on Earth depends on the photosynthetic conversion of solar energy into plant biomass. Humans have come to rely on many more energy flows—ranging from fossil fuels to photovoltaic generation of electricity—for their civilized existence. In this monumental history, Vaclav Smil provides a comprehensive account of how energy has shaped society, from pre-agricultural foraging societies through today's fossil fuel–driven civilization. Humans are the only species that can systematically harness energies outside their bodies, using the power of their intellect and an enormous variety of artifacts—from the simplest tools to internal combustion engines and nuclear reactors. The epochal transition to fossil fuels affected everything: agriculture, industry, transportation, weapons, communication, economics, urbanization, quality of life, politics, and the environment. Smil describes humanity's energy eras in panoramic and interdisciplinary fashion, offering readers a magisterial overview. This book is an extensively updated and expanded version of Smil's Energy in World History (1994). Smil has incorporated an enormous amount of new material, reflecting the dramatic developments in energy studies over the last two decades and his own research over that time.

An expansive, yet succinct, analysis of the Philosophy of Religion – from metaphysics through theology. Organized into two sections, the text first examines truths concerning what is possible and what is necessary. These chapters lay the foundation for the book’s second part – the search for a metaphysical framework that permits the possibility of an ultimate explanation that is correct and complete. A cutting-edge scholarly work which engages with the traditional metaphysician’s quest for a true ultimate explanation of the most general features of the world we inhabit Develops an original view concerning the epistemology and metaphysics of modality, or truths concerning what is possible or necessary Applies this framework to a re-examination of the cosmological argument for theism Defends a novel version of the Leibnizian cosmological argument

Everyone talks about style, but no one explains it. The authors of this book do; and in doing so, they provoke the reader to consider style, not as an elegant accessory of effective prose, but as its very heart. At a time when writing skills have virtually disappeared, what can be done? If only people learned the principles of verbal correctness, the essential rules, wouldn't good prose simply fall into place? Thomas and Turner say no. Attending to rules of grammar, sense, and sentence structure will no more lead to effective prose than knowing the mechanics of a golf swing will lead to a hole-in-one. Furthermore, ten-step programs to better writing exacerbate the problem by failing to recognize, as Thomas and Turner point out, that there are many styles with different standards. In the first half of Clear and Simple, the authors introduce a range of styles--reflexive, practical, plain, contemplative, romantic, prophetic, and others--contrasting them to classic style. Its principles are simple: The writer adopts the pose that the motive is truth, the purpose is presentation, the reader is an intellectual equal, and the occasion is informal. Classic style is at home in everything from business memos to personal letters, from magazine articles to university writing. The second half of the book is a tour of examples--the exquisite and the execrable--showing what has worked and what hasn't. Classic prose is found everywhere: from Thomas Jefferson to Junichirō Tanizaki, from Mark Twain to the observations of an undergraduate. Here are many fine performances in classic style, each clear and simple as the truth. Originally published in 1994. The Princeton Legacy Library uses the latest print-on-demand technology to again make available previously out-of-print books from the distinguished backlist of Princeton University Press. These editions preserve the original texts of these important books while presenting them in durable paperback and hardcover editions. The goal of the Princeton Legacy Library is to vastly increase access to the rich scholarly heritage found in the thousands of books published by Princeton University Press since its founding in 1905.

TO THE SECOND EDITION In the nine years since this book was first written, rapid progress has been made scientifically in nuclear fusion, space physics, and nonlinear plasma theory. At the same time, the energy shortage on the one hand and the exploration of Jupiter and Saturn on the other have increased the national awareness of the important applications of plasma physics to energy production and to the understanding of our space environment. In magnetic confinement fusion, this period has seen the attainment 13 of a Lawson number nTE of 2 x 10 cm -3 sec in the Alcator tokamaks at MIT; neutral-beam heating of the PL T tokamak at Princeton to KTi = 6. 5 keV; increase of average ß to 3%-5% in tokamaks at Oak Ridge and General Atomic; and the stabilization of mirror-confined plasmas at Livermore, together with injection of ion current to near field-reversal conditions in the 2XIIß device. Invention of the tandem mirror has given magnetic confinement a new and exciting dimension. New ideas have emerged, such as the compact torus, surface-field devices, and the EßT mirror-torus hybrid, and some old ideas, such as the stellarator and the reversed-field pinch, have been revived. Radiofrequency heat ing has become a new star with its promise of dc current drive. Perhaps most importantly, great progress has been made in the understanding of the MHD behavior of toroidal plasmas: tearing modes, magnetic Vll Vlll islands, and disruptions.

Both global warming and oil shortage can be solved by controlled fusion, a clean power source that will serve mankind for millennia. The idea of hydrogen fusion as well as its difficulties are presented in non-technical language to dispel the notion that fusion is always 50 years away. This book also summarizes the evidence for climate change and explains the principles of both fossil and "green" energy sources to show that fusion is the best alternative for central-station power in the near term as well as the far future. Praise for "An Indispensable Truth: How Fusion Power Can Save the Planet" "In this study Professor Chen outlines the underlying physics, recent progress in achieving advanced plasmas and magnetic confinement, and hopes for the future. He recognizes the difficulties that remain in engineering a fusion reactor, but he remains optimistic regarding ultimate success, yet fearful of the consequences were we to fail."- James R. Schlesinger, former Chairman, Atomic Energy Commission; Director, Central Intelligence Agency; Secretary of Defense; and Secretary of Energy "With lots of detail and examples, Chen brings the technical topic of fusion to life, making the book a great read for scientists and nonscientists alike."- Representative Rush Holt (D-NJ) "Professor Chen has opened the door to energy survival for our globe. His insightful analysis makes the case for fusion energy, and he conveys both its complexity and its promise. This book is a must for all those who are concerned about the energy future of our species."- Raymond L Orbach, former Undersecretary for Science, U.S. Department of Energy "This is an important book for anyone who wishes to understand the greatest challenge we face. Frank Chen makes the science of fusion and energy clear, compelling, and hugely enjoyable."- Steven Cowley, Director and CEO, Culham Centre for Fusion Energy, United Kingdom Atomic Energy Authority "

'Science has never had an advocate quite like David Deutsch ... A computational physicist on a par with his touchstones Alan Turing and Richard Feynman, and a philosopher in the line of his greatest hero, Karl Popper. His arguments are so clear that to read him is to experience the thrill of the highest level of discourse available on this planet and to understand it' Peter Forbes, Independent In our search for truth, how far have we advanced? This uniquely human quest for good explanations has driven amazing improvements in everything from scientific understanding and technology to politics, moral values and human welfare. But will progress end, either in catastrophe or completion - or will it continue infinitely? In this profound and seminal book, David Deutsch explores the furthest reaches of our current understanding, taking in the Infinity Hotel, supernovae and the nature of optimism, to instill in all of us a wonder at what we have achieved - and the fact that this is only the beginning of humanity's infinite possibility. 'This is Deutsch at his most ambitious, seeking to understand the implications of our scientific explanations of the world ... I enthusiastically recommend this rich, wide-ranging and elegantly written exposition of the unique insights of one of our most original intellectuals' Michael Berry, Times Higher Education Supplement 'Bold ... profound ... provocative and persuasive' Economist 'David Deutsch may well go down in history as one of the great scientists of our age' Scotsman
