The story of two brilliant nineteenth-century scientists who discovered the electromagnetic field, laying the groundwork for the amazing technological and theoretical breakthroughs of the twentieth century Two of the boldest and most creative scientists of all time were Michael Faraday (1791-1867) and James Clerk Maxwell (1831-1879). This is the story of how these two men - separated in age by forty years - discovered the existence of the electromagnetic field and devised a radically new theory which overturned the strictly mechanical view of the world that had prevailed since Newton's time. The authors, veteran science writers with special expertise in physics and engineering, have created a lively narrative that interweaves rich biographical detail from each man's life with clear explanations of their scientific accomplishments. Faraday was an autodidact, who overcame class prejudice and a lack of mathematical training to become renowned for his acute powers of experimental observation, technological skills, and prodigious scientific imagination. James Clerk Maxwell was highly regarded as one of the most brilliant mathematical physicists of the age. He made an enormous number of advances in his own right. But when he translated Faraday's ideas into mathematical language, thus creating field theory, this unified framework of electricity, magnetism and light became the basis for much of later, 20th-century physics. Faraday's and Maxwell's collaborative efforts gave rise to many of the technological innovations we take for granted today - from electric power generation to television, and much more. Told with panache, warmth, and clarity, this captivating story of their greatest work - in which each played an equal part - and their inspiring lives will bring new appreciation to these giants of science.

An engrossing history of the science of one of the four fundamental physical forces in the universe, electromagnetism, right up to the latest indications that the poles are soon to reverse and destroy the world's power grids and electronic communications A cataclysmic planetary phenomenon is gathering force deep within the Earth. The magnetic North Pole will eventually trade places with the South Pole. Satellite evidence suggests to some scientists that the move has already begun, but most still think it won't happen for many decades. All agree that it has happened many times before and will happen again. But this time it will be different. It will be a very bad day for modern civilization. Award-winning science journalist Alanna Mitchell's delightful storytelling introduces enchanting characters from investigations into magnetism in thirteenth-century France to the discovery in the Victorian era that electricity and magnetism emerge from the same force. No one has ever told so eloquently how the Earth itself came to be seen as a magnet, spinning in space with two poles, and that those poles dramatically, catastrophically reverse now and then... The recent finding that Earth's magnetic force field is decaying faster than previously thought, raising fears of an imminent pole reversal, ultimately gives The Spinning Magnet a spine-tingling urgency. When the poles switch, a process that takes many years, Earth is unprotected from solar radiation storms that would, among other things, wipe out all electromagnetic technology. No satellites, no Internet, no smartphones--maybe no power grid at all. Alanna Mitchell offers a beautifully crafted narrative history of ideas and science that readers of Stephen Greenblatt and Sam Kean will love.

Science and faith have had a long intertwined history. The relationship has run the gamut from a total disconnect to an adversarial battleground where proponents of each claim total victory. However, if God created the physical world and remains active in the physical world, we cannot ignore the interaction nor can we assume or expect a world of conflict. While nineteenth-century physics brought classical physics—which quite reasonably divorced God and nature—to a culmination, twentieth-century physics, especially quantum physics, has opened a new realm of possible interactions. Even though one can reasonably say that no one understands quantum physics, the fruits of the discipline overflow the cornucopia. People of faith can share the feast; and people of science are welcome at the table of faith.

An Enlightening Way to Navigate through Mind-Boggling Physics Concepts Physics Curiosities, Oddities, and Novelties highlights unusual aspects of physics and gives a new twist to some fundamental concepts. The book covers both classical and modern physics in an engaging, straightforward style. The author presents perplexing questions that often lack satisfying answers. He also delves into the stories of famous and eccentric past scientists. Many examples reveal interesting ideas, including how: Newton had trouble determining the mass of the moon An electric motor is an electric generator run in reverse Time travel that violates causality is not possible Schrödinger’s cat may be both dead and alive, and there may be two of each one of us to observe the two possibilities Particle physics and the basic laws of thermodynamics can appear simple yet are very complicated Accessible to nonspecialists and beginning students, this book provides insight into physics using minimal mathematics and jargon. It summarizes many fascinating aspects of physics employing only essential formulas. Some familiar formulas are written in standard form while other equations are written in words for greater clarity.
