The Physical Universe

"This is a truly astonishing book, invaluable for anyone with an interest in astronomy." Physics Bulletin "Just the thing for a first year university science course." Nature "This is a beautiful book in both concept and execution." Sky & Telescope

This is an outstanding text with a long history that has been updated and given a fresh look, including worked examples pulled out of the text into numbered boxes. The text is now also accompanied by stronger media support with "CPS" eInstruction student response system questions, more extensive online quizzing, and PowerPoint lectures. Aimed at presenting the essentials of physics, chemistry, earth science, and astronomy in a clear, easy-to-understand way, The Physical Universe shows students how science works, how scientists approach problems, and why science constantly evolves in its search for understanding. The text can also be packaged with its long time companion student study guide, which includes a review of chapter terms and concepts; self quizzing for extra practice; and solved problems from the text. .

-The aim of this text is to present, as simply and clearly as possible, the essentials of physics, chemistry, geology, and astronomy.

An overview of fine-tuning arguments in physics, for students and researchers in physics and philosophy.

How is it possible for the world as we experience it to exist embedded in the physical universe? How can there be sensory qualities, consciousness, freedom, science and art, friendship, love, justice--all that which gives meaning and value to life--if the world really is more or less as modern science tells us it is? This is the problem that is tackled by this book. The solution proposed is that physics describes only a selected aspect of all that exists--that aspect which determines the way events unfold. Sensory qualities, inner experiences, consciousness, meaning and value, all these exist but lie beyond the scope of physics, and of that part of science that can be reduced to physics. Furthermore, these human features of the world are to be explained and understood, not scientifically, but "personalistically," a kind of understanding distinct from, and not reducible to, science. This view that the world is riddled with what may be called "double comprehensibility" leads to a proposed solution to the philosophical mind/body problem, and to the problem of free will; it leads to a reinterpretation of Darwin's theory of evolution, and to an account of the evolution of consciousness and free will. After a discussion of the location of consciousness in the brain, the book concludes with a proposal as to how academic inquiry might be changed so that it becomes a kind of inquiry rationally designed to help humanity create a more civilized human world in the physical universe.

"The question for me is how can the human mind occur in the physical universe. We now know that the world is governed by physics. We now understand the way biology nestles comfortably within that. The issue is how will the mind do that as well."--Allen Newell, December 4, 1991, Carnegie Mellon University The argument John Anderson gives in this book was inspired by the passage above, from the last lecture by one of the pioneers of cognitive science. Newell describes what, for him, is the pivotal question of scientific inquiry, and Anderson gives an answer that is emerging from the study of brain and behavior. Humans share the same basic cognitive architecture with all primates, but they have evolved abilities to exercise abstract control over cognition and process more complex relational patterns. The human cognitive architecture consists of a set of largely independent modules associated with different brain regions. In this book, Anderson discusses in detail how these various modules can combine to produce behaviors as varied as driving a car and solving an algebraic equation, but focuses principally on two of the modules: the declarative and procedural. The declarative module involves a memory system that, moment by moment, attempts to give each person the most appropriate possible window into his or her past. The procedural module involves a central system that strives to develop a set of productions that will enable the most adaptive response from any state of the modules. Newell argued that the answer to his question must take the form of a cognitive architecture, and Anderson organizes his answer around the ACT-R architecture, but broadens it by bringing in research from all areas of cognitive science, including how recent work in brain imaging maps onto the cognitive architecture.
