But what about relativity? Physics professor Chad Orzel and his inquisitive canine companion, Emmy, tackle the concepts of general relativity in this irresistible introduction to Einstein’s physics. Through armchair ”and sometimes passenger-seat” conversations with Emmy about the relative speeds of dog and cat motion or the logistics of squirrel-chasing, Orzel translates complex Einsteinian ideas, i.e., ”the slowing of time for a moving observer, the shrinking of moving objects, the effects of gravity on light and time, black holes, the Big Bang, and of course, E=mc2” into examples simple enough for a dog to understand.A lively romp through one of the great theories of modern physics, How to Teach Relativity to Your Dog will teach you everything you ever wanted to know about space, time, and anything else you might have slept through in high school physics class.

    This is such a book. Max Born is a Nobel Laureate (1955) and one of the world's great physicists: in this book he analyzes and interprets the theory of Einsteinian relativity. The result is undoubtedly the most lucid and insightful of all the books that have been written to explain the revolutionary theory that marked the end of the classical and the beginning of the modern era of physics.The author follows a quasi-historical method of presentation. The book begins with a review of the classical physics, covering such topics as origins of space and time measurements, geometric axioms, Ptolemaic and Copernican astronomy, concepts of equilibrium and force, laws of motion, inertia, mass, momentum and energy, Newtonian world system (absolute space and absolute time, gravitation, celestial mechanics, centrifugal forces, and absolute space), laws of optics (the corpuscular and undulatory theories, speed of light, wave theory, Doppler effect, convection of light by matter), electrodynamics (including magnetic induction, electromagnetic theory of light, electromagnetic ether, electromagnetic laws of moving bodies, electromagnetic mass, and the contraction hypothesis). Born then takes up his exposition of Einstein's special and general theories of relativity, discussing the concept of simultaneity, kinematics, Einstein's mechanics and dynamics, relativity of arbitrary motions, the principle of equivalence, the geometry of curved surfaces, and the space-time continuum, among other topics. Born then points out some predictions of the theory of relativity and its implications for cosmology, and indicates what is being sought in the unified field theory.This account steers a middle course between vague popularizations and complex scientific presentations. This is a careful discussion of principles stated in thoroughly acceptable scientific form, yet in a manner that makes it possible for the reader who has no scientific training to understand it. Only high school algebra has been used in explaining the nature of classical physics and relativity, and simple experiments and diagrams are used to illustrate each step. The layman and the beginning student in physics will find this an immensely valuable and usable introduction to relativity. This Dover 1962 edition was greatly revised and enlarged by Dr. Born.

    One of the world's leading astronomers, Robert Kirshner, takes readers inside a lively research team on the quest that led them to an extraordinary cosmological discovery: the expansion of the universe is accelerating under the influence of a dark energy that makes space itself expand. In addition to sharing the story of this exciting discovery, Kirshner also brings the science up-to-date in a new epilogue. He explains how the idea of an accelerating universe--once a daring interpretation of sketchy data--is now the standard assumption in cosmology today.This measurement of dark energy--a quality of space itself that causes cosmic acceleration--points to a gaping hole in our understanding of fundamental physics. In 1917, Einstein proposed the cosmological constant to explain a static universe. When observations proved that the universe was expanding, he cast this early form of dark energy aside. But recent observations described first-hand in this book show that the cosmological constant--or something just like it--dominates the universe's mass and energy budget and determines its fate and shape.Warned by Einstein's blunder, and contradicted by the initial results of a competing research team, Kirshner and his colleagues were reluctant to accept their own result. But, convinced by evidence built on their hard-earned understanding of exploding stars, they announced their conclusion that the universe is accelerating in February 1998. Other lines of inquiry and parallel supernova research now support a new synthesis of a cosmos dominated by dark energy but also containing several forms of dark matter. We live in an extravagant universe with a surprising number of essential ingredients: the real universe we measure is not the simplest one we could imagine.

    A study of the available evidence will challenge you and much of what you assumed to be true. "Now we are discovering that there is a highly-sophisticated black-ops weaponization of free energy technology and it was responsible for the bizarre, low-temperature pulverization of the Twin Towers. Dr. Judy Wood has pieced together the physical evidence and Andrew Johnson has highlighted who is working to silence or smear whom, as the powers that be rush to impede or at least contain the dissemination of these startling findings." - Conrado Salas Cano, M.S. in Physics ** NOTE: Book is sold at the cheapest possible price on the Amazon Kindle Store - if you hunt round, you can find it for free. **

    Comparing the key events of the Old Testament with the latest findings in physics, biochemistry, and paleontology, a physicist and theologian shows that science and the Bible can be reconciled to resolve the age-old debates about God.

    As they see matters, wealth in the form of means of production and wealth in the form of consumers’ goods are essentially indistinguishable. For all practical purposes, they have no awareness of the existence of capital and of its importance. Thus, capitalists are generally depicted as fat men, whose girth allegedly signifies an excessive consumption of food and of wealth in general, while their alleged victims, the wage earners, are typically depicted as substantially underweight, allegedly signifying their inability to consume, thanks to the allegedly starvation wages paid by the capitalists.The truth is that in a capitalist economic system, the wealth of the capitalists is not only overwhelmingly in the form of means of production, such as factory buildings, machinery, farms, mines, stores, warehouses, and means of transportation and communication, but all of this wealth is employed in producing for the market, where its benefit is made available to everyone in the economic system who is able to afford to buy its products.Consider. Whoever can afford to buy an automobile benefits from the existence of the automobile factory and its equipment where that car was made. He also benefits from the existence of all the other automobile factories, whose existence and competition served to reduce the price he had to pay for his automobile. He benefits from the existence of the steel mill that provided the steel for his car, and from the iron mine that provided the iron ore needed for the production of that steel, and, of course, from the existence of all the other steel mills and iron mines whose existence and competition served to hold down the prices of the steel and iron ore that contributed to the production of his car.And, thanks to the great magnitude of wealth employed as capital, the demand for labor, of which capital is the foundation, is great enough and thus wages are high enough that virtually everyone is able to afford to a substantial degree most of the products of the economic system. For the capital of the capitalists is the foundation both of the supply of products that everyone buys and of the demand for the labor that all wage earners sell. More capital—a greater amount of wealth in the possession of the capitalists—means a both a larger and better supply of products for wage earners to buy and a greater demand for the labor that wage earners sell. Everyone, wage earners and capitalists alike, benefits from the wealth of the capitalists, because, as I say, that wealth is the foundation of the supply of the products that everyone buys and of the demand for the labor that all wage earners sell. More capital in the hands of the capitalists always means a more abundant, better quality of goods and services offered for sale and a larger demand for labor. The further effect is lower prices and higher wages, and thus a higher standard of living for wage earners.Furthermore, the combination of the profit motive and competition operates continually to improve the products offered in the market and the efficiency with which they are produced, thus steadily further improving the standard of living of everyone.In the alleged conflict between the so-called 99 percent and the so-called 1 percent, the program of the 99 percent is to seize as far as possible the wealth of the 1 percent and consume it. To the extent that it is enacted, the effect of this program can only be to impoverish everyone, and the 99 percent to a far greater extent than the 1 percent. To the extent that the 1 percent loses its mansions, luxury cars, and champagne and caviar, 99 times as many people lose their houses, run-of-the mill cars, and steak and hamburger.

    The book begins with relevant scientific fundamentals and progresses through an exploration of the solar system, stars, galaxies, and cosmology. The Astronomy textbook builds student understanding through the use of relevant analogies, clear and non-technical explanations, and rich illustrations. Mathematics is included in a flexible manner to meet the needs of individual instructors.

    But recent technological advances have made the question both practical and urgent. A brilliantly imaginative group of physicists at Oxford University have risen to the challenge. This is their story. At long last, there is a sensible way to think about quantum mechanics. The new view abolishes the need to believe in randomness, long-range spooky forces, or conscious observers with mysterious powers to collapse cats into a state of life or death. But the new understanding comes at a price: we must accept that we live in a multiverse wherein countless versions of reality unfold side-by-side. The philosophical and personal consequences of this are awe-inspiring.The new interpretation has allowed imaginative physicists to conceive of wonderful new technologies: measuring devices that effectively share information between worlds and computers that can borrow the power of other worlds to perform calculations. Step by step, the problems initially associated with the original many-worlds formulation have been addressed and answered so that a clear but startling new picture has emerged.Just as Copenhagen was the centre of quantum discussion a lifetime ago, so Oxford has been the epicenter of the modern debate, with such figures as Roger Penrose and Anton Zeilinger fighting for single-world views, and David Deutsch, Lev Vaidman and a host of others for many-worlds.An independent physicist living in Oxford, Bruce has had a ringside seat to the debate. In his capable hands, we understand why the initially fantastic sounding many-worlds view is not only a useful way to look at things, but logically compelling. Parallel worlds are as real as the distant galaxies detected by the Hubble Space Telescope, even though the evidence for their existence may consist only of a few photons.
