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.

Feynman lectures on computation

Feynman, Richard P.
From 1983 to 1986, the legendary physicist and teacher Richard Feynman gave a course at Caltech called “Potentialities and Limitations of Computing Machines.”Although the lectures are over ten years old, most of the material is timeless and presents a “Feynmanesque” overview of many standard and some not-so-standard topics in computer science. These include computability, Turing machines (or as Feynman said, “Mr. Turing's machines”), information theory, Shannon's Theorem, reversible computation, the thermodynamics of computation, the quantum limits to computation, and the physics of VLSI devices. Taken together, these lectures represent a unique exploration of the fundamental limitations of digital computers.Feynman's philosophy of learning and discovery comes through strongly in these lectures. He constantly points out the benefits of playing around with concepts and working out solutions to problems on your own-before looking at the back of the book for the answers. As Feynman says in the lectures: “If you keep proving stuff that others have done, getting confidence, increasing complexities of your solutions-for the fun of it-then one day you'll turn around and discovers that nobody actually did that one! And that's the way to become a computer scientist.”

Adventures of a computational explorer

Wolfram, Stephen
Through his pioneering work in science, technology and language design, Stephen Wolfram has developed his own signature way of thinking about an impressive range of subjects. From science consulting for a Hollywood movie, solving problems of AI ethics, hunting for the source of an unusual polyhedron, communicating with extraterrestrials, to finding the fundamental theory of physics and exploring the digits of pi, Adventures of a Computational Explorer captures the infectious energy and curiosity of one of the great pioneers of the computational world.

The human test: how predictability, creativity, and the quantum mind will redefine life in the age of AI

Folman, Ron
"As data harvesting continues its exponential growth and computing power increases beyond what we can even imagine, AI and Big Data will be able to predict what we want for breakfast, what shoes we will buy, which political party we will vote for, and who we will fancy in a bar. Indeed, these deep-learning machines will know us better than we know ourselves. The day awaits when academia and big business will be able to quantify just how predictable each of us are. If indeed we are predictable like machines, to what extent are we alive, and under what definition? In The Human Test, quantum physicist Ron Folman unites findings from cognitive science, quantum physics, philosophy, and technology to offer a prescient look into this startling new era of human existence. If we are indeed found to be predictable, it will change everything we thought we knew about human nature. The Human Test strives for a new paradigm, and this new paradigm is found in human predictability. Existing monitors of general brain activity measure only very rudimentary aspects of the human experience, or what may be called human life; could the advent of a disruptive new technology bring about a much more insightful measure of who we are? While The Human Test describes a new and profound near-future impact of AI, it is rooted in a topic of paramount importance to humans: the enigma of consciousness and how it defines human life-or, what differentiates humans from all other life forms. Ultimately, The Human Test addresses some of the most fundamental questions about our species, starting with the most crucial: do we have free will, or are we merely machines? Fortunately, there is an antidote to predictability: creativity, that wondrous state of being original and inherently not predictable. Ultimately, Folman argues that if we can understand predictability, we can learn how to distance ourselves from it, and transcend to a purer idea of what human life should look like"-- Provided by publisher.

Electromagnetic Field Computation by Network Methods

Leopold B. Felsen,Mauro Mongiardo,Peter Russer
In this monograph, the authors propose a systematic and rigorous treatment of electromagnetic field representations in complex structures. The architecture suggested in this book accommodates use of different numerical methods as well as alternative Green's function representations in each of the subdomains resulting from a partitioning of the overall problem. The subdomains are regions of space where electromagnetic energy is stored and are described in terms of equivalent circuit representations based either on lumped element circuits or on transmission lines. Connection networks connect the subcircuits representing the subdomains. The connection networks are lossless, don't store energy and represent the overall problem topology. This is similar to what is done in circuit theory and permits a phrasing of the solution of EM field problems in complex structures by Network-oriented methods.

A short course in computational science and engineering: C++, Java, and Octave numerical programming with free software tools

Yevick, David
"Building on his highly successful textbook on C++, David Yevick provides a concise yet comprehensive one-stop course in three key programming languages, C++, Java and Octave (a freeware alternative to MATLAB). Employing only public-domain software to ensure straightforward implementation for all readers, this book presents a unique overview of numerical and programming techniques relevant to scientific programming, including object-oriented programming, elementary and advanced topics in numerical analysis, physical system modeling, scientific graphics, software engineering and performance issues. Relevant features of each programming language are illustrated with short, incisive examples, and the installation and application of the software is described in detail. Compact, transparent code in all three programming languages is applied to the fundamental equations of quantum mechanics, electromagnetics, mechanics and statistical mechanics. Uncommented versions of the code that can be immediately modified and adapted are provided online for the more involved programs. This compact, practical text is an invaluable introduction for students in all undergraduate- and graduate-level courses in the physical sciences or engineering that require numerical modeling, and also a key reference for instructors and scientific programmers"--
