This book discusses analogies between relativistic cosmology and various physical systems or phenomena, mostly in the earth sciences, that are described formally by the same equations. Of the two independent equations describing the universe as a whole, one (the Friedmann equation) has the form of an energy conservation equation for one-dimensional motion. The second equation is fairly easy to satisfy (although not automatic): as a result, cosmology lends itself to analogies with several systems. Given that a variety of universes are mathematically possible, several analogies exist. Analogies discussed in this book include equilibrium beach profiles, glacial valleys, the shapes of glaciers, heating/cooling models, freezing bodies of water, capillary fluids, Omori's law for earthquake aftershocks, lava flows, and a few mathematical analogies (Fibonacci's sequence, logistic equation, geodesics of various spaces, and classic variational problems). A century of research in cosmology can solve problems on the other side of an analogy, which in turn can suggest ideas in gravity. Finding a cosmic analogy solves the inverse variational problem of finding a Lagrangian and a Hamiltonian for that system, when nobody thought one exists. Often, the symmetries of the cosmological equations translate in new symmetries of the analogous system. The book surprises the reader with analogies between natural systems and exotic systems such as possible universes.

Space weaponry, satellite surveillance and communications, and private space travel are all means in which outer space is being humanized: incorporated into society’s projects. But what are the political implications of society not only being globalized, but becoming ‘cosmic’? Our ideas about society have long affected, and been affected by, our understanding of the universe: large sections of our economy and society are now organized around humanity’s use of outer space. Our view of the universe, our increasingly ‘cosmic’ society, and even human consciousness are being transformed by new relations with the cosmos. As the first sociological book to tackle humanity’s relationship with the universe, this fascinating volume links social theory to classical and contemporary science, and proposes a new ‘cosmic’ social theory. Written in a punchy, student-friendly style, this timely book engages with a range of topical issues, including cyberspace, terrorism, tourism, surveillance and globalization.

Alpine Physics: Science In The Mountain Environment

This unique volume applies physics and basic science to the mountain environment and is written in a non-technical language for curious laypeople who wonder why or how natural phenomena happen, and what their scientific explanation may be. The book discusses physics in a non-specialized way. Alpine Physics is mostly organized in categories relevant for non-scientists with an interest in alpine environments.Intuitive decision-making is often just grounded in plain common sense, to which mountain and nature lovers relate easily, especially when involving high-stakes decisions based on the estimation of such a treacherous environment. The book highlights how this intuitive decision-making can be complemented and augmented by basic scientific knowledge, and with better understanding it leads one to become a rational decision-maker.The book stimulates its readers to reason and discover why things are the way they are, at high altitudes, where many risk factors are aggravated, often dramatically, by steep gradients. The writing style marries that of the conventional science textbook and that of the informal North-American climbing guidebooks.

This work presents a series of dramatic discoveries never before made public. Starting from a collection of simple computer experiments---illustrated in the book by striking computer graphics---Wolfram shows how their unexpected results force a whole new way of looking at the operation of our universe. Wolfram uses his approach to tackle a remarkable array of fundamental problems in science: from the origin of the Second Law of thermodynamics, to the development of complexity in biology, the computational limitations of mathematics, the possibility of a truly fundamental theory of physics, and the interplay between free will and determinism.

NATIONAL BESTSELLER • The renowned theoretical physicist and national bestselling author of The God Equation details the developments in computer technology, artificial intelligence, medicine, space travel, and more, that are poised to happen over the next century. “Mind-bending…. [An] alternately fascinating and frightening book.” —San Francisco Chronicle Space elevators. Internet-enabled contact lenses. Cars that fly by floating on magnetic fields. This is the stuff of science fiction—it’s also daily life in the year 2100. Renowned theoretical physicist Michio Kaku considers how these inventions will affect the world economy, addressing the key questions: Who will have jobs? Which nations will prosper? Kaku interviews three hundred of the world’s top scientists—working in their labs on astonishing prototypes. He also takes into account the rigorous scientific principles that regulate how quickly, how safely, and how far technologies can advance. In Physics of the Future, Kaku forecasts a century of earthshaking advances in technology that could make even the last centuries’ leaps and bounds seem insignificant.
