THE EMPEROR'S NEW MIND: Concerning Computers, Minds, and the Laws of Physics

Penrose, Roger
For decades, proponents of artificial intelligence have argued that computers will soon be doing everything that a human mind can do. Admittedly, computers now play chess at the grandmaster level, but do they understand the game as we do? Can a computer eventually do everything a human mind can do? In this absorbing and frequently contentious book, Roger Penrose--eminent physicist and winner, with Stephen Hawking, of the prestigious Wolf prize--puts forward his view that there are some facets of human thinking that can never be emulated by a machine. Penrose examines what physics and mathematics can tell us about how the mind works, what they can't, and what we need to know to understand the physical processes of consciousness. He is among a growing number of physicists who think Einstein wasn't being stubborn when he said his "little finger" told him that quantum mechanics is incomplete, and he concludes that laws even deeper than quantum mechanics are essential for the operation of a mind. To support this contention, Penrose takes the reader on a dazzling tour that covers such topics as complex numbers, Turing machines, complexity theory, quantum mechanics, formal systems, Godel undecidability, phase spaces, Hilbert spaces, black holes, white holes, Hawking radiation, entropy, quasicrystals, the structure of the brain, and scores of other subjects. The Emperor's New Mind will appeal to anyone with a serious interest in modern physics and its relation to philosophical issues, as well as to physicists, mathematicians, philosophers and those on either side of the AI debate.

The Logic of Scientific Discovery

Karl R. Popper
2024 Hardcover Reprint of Original 1959 Edition. Exact facsimile of the original edition, not reproduced with Optical Recognition Software. This book by one of the world's foremost philosophers of science presented a striking new picture of the logical character of scientific discovery--a picture which does full justice to the liberating effect of the Einsteinian revolution in physics and its immense impact upon scientific thought in general. For this new English edition Dr. Popper did his own translation and has written 150 pages of entirely new text. Ernest Nagel considered this work "a first rate contribution to the logic of scientific method. The book contains a very interesting chapter on quantum mechanics, which performs one of the few sensible analyses of the Indeterminacy Principle which I have seen in print... The book is highly stimulating and contains much that is bed-rock for future work."--From the Dusk Jacket.

Einstein on Einstein: autobiographical and scientific reflections

Gutfreund, Hanoch,Renn, Jürgen
"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"--

A project to find the fundamental theory of physics

Wolfram, Stephen
'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.

The Nature of Mathematical Modeling (Cambridge Series on Information and the Natural Sciences)

Gershenfeld, Neil
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.

The Cosmic Landscape String Theory and the Illusion of Intelligent Design

Leonard Susskind
The beginning of the 21st century is a watershed in modern science, a time that will forever change our understanding of the universe, Susskind contends. Several decades ago, he introduced the revolutionary concept of string theory to the world of physical science. In doing so, he inspired a generation of physicists who believed that the theory would uniquely predict the properties of our universe. Now, in his first book, Susskind argues that the very idea of such an "elegant theory" no longer suits our understanding of the universe, and that our narrow 20th-century view of a unique universe will have to give way to the much broader concept of a gigantic cosmic landscape--a megaverse, pregnant with new possibilities.--[Résumé de l'éditeur].

Exoplanet atmospheres: physical processes

Seager, Sara
Over the past twenty years, astronomers have identified hundreds of extrasolar planets--planets orbiting stars other than the sun. Recent research in this burgeoning field has made it possible to observe and measure the atmospheres of these exoplanets. This is the first textbook to describe the basic physical processes--including radiative transfer, molecular absorption, and chemical processes--common to all planetary atmospheres, as well as the transit, eclipse, and thermal phase variation observations that are unique to exoplanets. In each chapter, Sara Seager offers a conceptual introduction, examples that combine the relevant physics equations with real data, and exercises. Topics range from foundational knowledge, such as the origin of atmospheric composition and planetary spectra, to more advanced concepts, such as solutions to the radiative transfer equation, polarization, and molecular and condensate opacities. Since planets vary widely in their atmospheric properties, Seager emphasizes the major physical processes that govern all planetary atmospheres. Moving from first principles to cutting-edge research, Exoplanet Atmospheres is an ideal resource for students and researchers in astronomy and earth sciences, one that will help prepare them for the next generation of planetary science. The first textbook to describe exoplanet atmospheres Illustrates concepts using examples grounded in real data Provides a step-by-step guide to understanding the structure and emergent spectrum of a planetary atmosphere Includes exercises for students
