Here is astounding speculation about where the next giant step for mankind will take us. . . . Praise for Extraterrestrial Civilizations "[Isaac] Asimov holds our attention as he builds a meticulous case. We are not alone. It's just a matter of time until we know for sure." -- Miami Herald "Intriguing" -- Publishers Weekly

"Einstein begins his Autobiographical Notes with one problem he never quite solved: "What, precisely, is thinking?" To answer, he turns inward to the very shape of his thoughts, the ongoing struggle to connect local observation, or what he calls the "momentary and personal," to the larger "mental grasp of things." Einstein situates his greatest discoveries amongst the other twentieth-century breakthroughs in the field and closely examines how these discoveries punctuated and propelled his own intellectual development. The autobiography expands what we know about Einstein's childhood education, readings in philosophy, and journey to the theory of general relativity. In this book, Autobiographical Notes is accompanied by introductions, essays, and commentary by Hanoch Gutfreud and Jürgen Renn, who draw on biographical information, written correspondence, and their knowledge of Einstein scholarship to render these difficult texts accessible to readers. They have also collected critical writings by Einstein's contemporaries alongside Einstein's own responses to these interlocutors, as well as Einstein's Autobiographical Sketch, composed just before his death in 1955, which is published for the first time in English"--

The Evolution Of Physics Includes the rise of the mechanical view, the decline of the mechanical view, field, relativity and quanta.

From Canada's leading mind on contemporary physics, a daring new vision of the universe, and the scandals controversies, and questions that will illuminate our future. Quantum physics is the golden child of modern science. It is the basis of our understanding of our world--atoms, radiation, elementary particles, basic forces and the behavior of materials. But for a century it has also been the problem child of science, plagued by intense disagreements between its inventors, strange paradoxes, and implications that seem like the stuff of fantasy. In Einstein's Unfinished Revolution , theoretical physicist Lee Smolin takes us on a journey through the basics of quantum physics, introducing the stories of the experiments and figures that have transformed our understanding of the universe, before wrestling with the puzzles and conundrums that the quantum world presents. Along the way, he illuminates the existing theories that might solve these problems, guiding us towards a vision of the quantum that embraces common sense realism. Vibrant and accessible, Einstein's Unfinished Revolution brings us a step closer to resolving one of the greatest scientific controversies of our age.

A Nobel Laureate offers impressions and recollections of the development of modern physics. Rather than a chronological approach, Segrè emphasizes interesting, complex personalities who often appear only in footnotes. Readers will find that this book adds considerably to their understanding of science and includes compelling topics of current interest. 1980 edition.

The Nobel Prize-winning physicist and bestselling author of The First Three Minutes describes the grand quest for a unifying theory of nature--one that can explain forces as different as the cohesion inside the atom and the gravitational tug between the sun and Earth. Wirting with dazzling elegance and clarity, he retraces the steps that have led modern scientists from relativity and quantum mechanics to the notion of super-strings and the idea that our universe may coexist with others. But Weinberg asks as many questions as he answers, among them: Why does each explanation of the way nature works point to other, deeper explanations? Why are the best theories not only logical but beautiful? And what implications will a final theory have for our philosophy and religious faith? Intellectually daring, rich in anecdote and aphorism, Dreams of a Final Theory launches us into a new cosmos and helps us make sense of what we find there.

'In many ways it s the ultimate question in natural science: How does our universe work? Is there a fundamental theory? An incredible amount has been figured out about physics over the past few hundred years. But even with everything that s been done and it's very impressive - we still, after all this time, don t have a truly fundamental theory of physics.' The Wolfram Physics Project is a bold effort to find the fundamental theory of physics. It combines new ideas with the latest research in physics, mathematics and computation in the push to achieve this ultimate goal of science. Written with Stephen Wolfram's characteristic expository flair, this book provides a unique opportunity to learn about a historic initiative in science right as it is happening. A Project to Find the Fundamental Theory of Physics includes: The announcement of the project; A technical introduction; A history section that outlines the backstory which led Wolfram to this point; Background information from computational essays published by the author in 2015 and 2017; Foundational information, including historical notes and an excerpt from Wolfram's; 2002 New York Times Best Seller A New Kind of Science; Hundreds of beautiful full-colour visualisations. Stephen Wolfram is a distinguished scientist and best-selling author, and the creator of some of the world's most respected software systems, including Mathematica, Wolfram|Alpha and Wolfram Language. For more than 30 years he has been the CEO of the global technology company Wolfram Research.

Provides a comprehensive treatment of semiconductor device physics and technology, with emphasis on modern planar silicon devices. Physical principles are explained by the use of simple physical models and illustrated by experimental measurements.

This book about Aristotle, Galileo, Newton and others was written by the famed science writer Asimov. A volume from the fascinating series designed for students and layman alike.

This book first covers exact and approximate analytical techniques (ordinary differential and difference equations, partial differential equations, variational principles, stochastic processes); numerical methods (finite differences for ODE's and PDE's, finite elements, cellular automata); model inference based on observations (function fitting, data transforms, network architectures, search techniques, density estimation); as well as the special role of time in modeling (filtering and state estimation, hidden Markov processes, linear and nonlinear time series). Each of the topics in the book would be the worthy subject of a dedicated text, but only by presenting the material in this way is it possible to make so much material accessible to so many people. Each chapter presents a concise summary of the core results in an area, providing an orientation to what they can (and cannot) do, enough background to use them to solve typical problems, and pointers to access the literature for particular applications.

Chronicles the intellectual and technical discoveries that constitute the developments of refracting, reflecting, and radio telescopes, and related instruments, the personalities involved, and the astronomical knowledge gained by each advance

Hailed by the "Journal of the History of Astronomy" as "charming and witty," this chronicle by a renowned physicist traces the development of scientific thought from the works of the "founding fathers" Galileo, Huygens, and Newton to the more recent discoveries of Maxwell, Boltzmann, and Gibbs. 1984 edition.

This classic text introduces engineering students to the first principles of major phenomena and devices of optoelectronics and optical communication technology. Yariv's "first principles" approach employs real-life examples and extensive problems. The text includes separate chapters on quantum well and semiconductor lasers, as well as phase conjugation and its applications. Optical fiber amplification, signal and noise considerations in optical fiber systems, laser arrays and distributed feedback lasers all are covered extensively in major sections within chapters.

"What can fashionable ideas, blind faith, or pure fantasy possibly have to do with the scientific quest to understand the universe? Surely, theoretical physicists are immune to mere trends, dogmatic beliefs, or flights of fancy? In fact, acclaimed physicist and best-selling author Roger Penrose argues that researchers working at the extreme frontiers of physics are just as susceptible to these forces as anyone else. In this provocative book, he argues that fashion, faith, and fantasy, while sometimes productive and even essential in physics, may be leading today's researchers astray in three of the field's most important areas--string theory, quantum mechanics, and cosmology ... The result is an important critique of some of the most significant developments in physics today from one of its most eminent figures."--Jacket.

Roger Penrose's original and provocative ideas about the large-scale physics of the Universe, the small-scale world of quantum physics and the physics of the mind have been the subject of controversy and discussion. These ideas were proposed in his best-selling books The Emperor's New Mind and Shadows of the Mind. In this book, he summarises and updates his current thinking in these complex areas to present a masterful summary of those areas of physics in which he feels there are major unresolved problems. Through this, he introduces radically new concepts which he believes will be fruitful in understanding the workings of the brain and the nature of the human mind. These ideas are challenged by three distinguished experts from different backgrounds: Abner Shimony and Nancy Cartwright as philosophers of science and Stephen Hawking as a theoretical physicist and cosmologist. Roger Penrose concludes with a response to their thought-provoking criticisms.
