A portrait of the Nobel Prize-winning physicist describes his contributions to the world of twentieth-century science, including his discovery of quarks and contributions to the field of complexity
Nothing travels faster than the speed of light, and light travels at one fixed speed. This idea is considered a foundation of modern physics, but what if it is wrong?Theoretical physicist Magueijo presents the idea that light traveled faster in the early universe than it does today. The varying speed of light theory solves some of the most intractable problems in cosmology, and could have major implications for the study of physics.
There is no more profound, enduring or fascinating question in all of science than that of how time, space, and matter began. Now John Barrow, who has been at the cutting edge of research in this area and has written extensively about it, guides us on a journey to the beginning of time, into a world of temperatures and densities so high that we cannot recreate them in a laboratory. With new insights, Barrow draws us into the latest speculative theories about the nature of time and the "inflationary universe," explains "wormholes," showing how they bear upon the fact of our own existence, and considers whether there was a "singularity" at the inception of the universe. Here is a treatment so up-to-date and intellectually rich, deaing with ideas and speculation at the farthest frontier of science, that neither novice nor expert will want to miss what Barrow has to say. The Origin of the Universe is "In the Beginning" for beginners--the latest information from a first-rate scientist and science writer.
Explains the physics behind each of the four ideas - the conservation of energy, the second law of thermodynamics, the theory of relativity, quantum mechanics - and deftly untangles for lay readers such knotty concepts as entropy, the relativity of time, and the Heisenberg uncertainty principle.
Can there be freedom and free will in a deterministic world? Renowned philosopher Daniel Dennett emphatically answers "yes " Using an array of provocative formulations, Dennett sets out to show how we alone among the animals have evolved minds that give us free will and morality. Weaving a richly detailed narrative, Dennett explains in a series of strikingly original
arguments--drawing upon evolutionary biology, cognitive neuroscience, economics, and philosophy--that far from being an enemy of traditional explorations of freedom, morality, and meaning, the evolutionary perspective can be an indispensable ally. In Freedom Evolves, Dennett seeks to place ethics on the foundation it deserves: a realistic, naturalistic, potentially unified vision of our place in nature.
If you want to know what's happening in the world, follow the heat.Why can't your coffee "steal" heat from the air to stay piping hot? Why can't Detroit make a car that's 100 percent efficient? Why can't some genius make a perpetual motion machine? The answers lie in the field of thermodynamics, the study of heat, which turns out to be the key to an astonishing number of scientific puzzles, including why time inexorably runs in only one direction. In Warmth Disperses and Time Passes: The History of Heat, physics professor Hans Christian von Baeyer tells the story of heat through the lives of the scientists who discovered it. With his trademark elegant prose, eye for lively detail, and gift for lucid explanation, Professor von Baeyer turns the contemplation of a cooling coffee cup into a beguiling portrait of the birth of a science with relevance to almost every aspect of our lives.
If you think a negative charge is something that shows up on your credit card bill -- if you imagine that Ohm's Law dictates how long to meditate -- if you believe that Newtonian mechanics will fix your car -- you need The Cartoon Guide to Physics to set you straight.You don't have to be a scientist to grasp these and many other complex ideas, because The Cartoon Guide to Physics explains them all: velocity, acceleration, explosions, electricity and magnetism, circuits -- even a taste of relativity theory -- and much more, in simple, clear, and, yes, funny illustrations. Physics will never be the same
In this "informative and delightful" (American Scientist) biography, Margaret Cheney explores the brilliant and prescient mind of Nikola Tesla, one of the twentieth century's greatest scientists and inventors.In Tesla: Man Out of Time, Margaret Cheney explores the brilliant and prescient mind of one of the twentieth century's greatest scientists and inventors. Called a madman by his enemies, a genius by others, and an enigma by nearly everyone, Nikola Tesla was, without a doubt, a trailblazing inventor who created astonishing, sometimes world-transforming devices that were virtually without theoretical precedent. Tesla not only discovered the rotating magnetic field -- the basis of most alternating-current machinery -- but also introduced us to the fundamentals of robotics, computers, and missile science. Almost supernaturally gifted, unfailingly flamboyant and neurotic, Tesla was troubled by an array of compulsions and phobias and was fond of extravagant, visionary experimentations. He was also a popular man-about-town, admired by men as diverse as Mark Twain and George Westinghouse, and adored by scores of society beauties.
From Tesla's childhood in Yugoslavia to his death in New York in the 1940s, Cheney paints a compelling human portrait and chronicles a lifetime of discoveries that radically altered -- and continue to alter -- the world in which we live. Tesla: Man Out of Time is an in-depth look at the seminal accomplishments of a scientific wizard and a thoughtful examination of the obsessions and eccentricities of the man behind the science.
