Book excerpt: The mystery of Earth's invisible, life-supporting power Alanna Mitchell's globe-trotting history of the science of electromagnetism and the Earth's magnetic field--right up to the latest indications that the North and South Poles may soon reverse, with apocalyptic results--will soon change the way you think about our planet. Award-winning journalist Alanna Mitchell's science storytelling introduce intriguing characters--from the thirteenth-century French investigations into magnetism and the Victorian-era discover that electricity and magnetism emerge from the same fundamental force to the latest research. 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 have dramatically reversed many time, often coinciding with mass extinctions. The most recent reversal was 780,000 years ago. Mitchell explores indications that the Earth's magnetic force field is decaying faster than previously thought. When the poles switch, a process that takes many years, the Earth is unprotected from solar radiation storms that would, among other disturbances, wipe out much and possible all of our electromagnetic technology. Navigation for all kinds of animals is disrupted without a stable, magnetic North Pole. But can you imagine no satellites, no Internet, no smartphones--maybe no power grids at all? Alanna Mitchell offers a beautifully crafted narrative history of surprising ideas and science, illuminating invisible parts of our own planet that are constantly changing around us.

A lecture by prof. A. M. ma yer, P/i.D. At the invitation of the Yale Scientific Club, I have the honor to appear before you to deliver a lecture on Magnetism--a subject to which I have given several years of devoted study. Confused by the multiplicity of the facts of this science, and embarrassed by the grandeur of its generalizations, I have resolved to do, what every public lecturer must do who would confer on his hearers any greater benefit than mere temporary amusement and that is, to select from this subject one prominent truth, and to present this to you in simple and striking experiments; but, so to describe and logically connect these experiments as clearly and forcibly to bring the truth before your minds and fix it there. That this method of procedure is necessary, will be evident when you consider that over one hundred men of the highest ability, as original investigators, have toiled, on an average of ten years each, at these problems of magnetism; thus making an aggregate of one thousand years of successful search in the rich mine of natural truth. From this vast accumulation of fact and of theory I s select as my text words given to the world over 270 years ago by Dr. William Gilbert, the physician to Queen Elizabeth. In the year 1600 Gilbert published a work entitled "De Magnete," or, "on the Magnet" (1). In this book I found my text, and thus it reads: "Magnus magnes ipse est globus terrestris," which being interpreted is, " the earth itself is a great magnet." Those who will examine this remarkable book of science cannot fail to observe how skillfully Gilbert handles the experimental or inductive method of research in arriving at the facts and the laws of magnetism; and if he cannot be style

Download or read book Our Magnetic Earth written by Ronald T. Merrill and published by University of Chicago Press. This book was released on 2010-11-15 with total page 270 pages. Available in PDF, EPUB and Kindle. Book excerpt: For the general public, magnetism often seems more the province of new age quacks, movie mad scientists, and grade-school teachers than an area of actual, ongoing scientific inquiry. But as Ronald T. Merrill reveals in Our Magnetic Earth, geomagnetism really is an enduring, vibrant area of science, one that offers answers to some of the biggest questions about our planet’s past—and maybe even its future. In a clear and careful fashion, he lays out the physics of geomagnetism and magnetic fields, then goes on to explain how Earth’s magnetic field provides crucial evidence for our understanding of continental drift and plate tectonics; how and why animals, ranging from bacteria to mammals, sense and use the magnetic field; how changes in climate over eons can be studied through variations in the magnetic field in rocks; and much more. Throughout, Merrill peppers his scientific account with bizarre anecdotes and fascinating details, from levitating pizzas to Moon missions to blackmailing KGB agents—a reminder that real science can at times be stranger, and more amusing, than fiction. A winning primer for anyone who has ever struggled with a compass or admired a ragged V of migrating geese, Our Magnetic Earth demonstrates that education and entertainment need not be polar opposites.

Book excerpt: An introductory guide to global magnetic field properties, Earth Magnetism addresses, in non-technical prose, many of the frequently asked questions about Earth's magnetic field. Magnetism surrounds and penetrates our Earth in ways basic science courses can rarely address. It affects navigation, communication, and even the growth of crystals. As we observe and experience an 11-year solar maximum, we may witness spectacular satellite-destroying solar storms as they interact with our magnetic field. Written by an acknowledged expert in the field, this book will enrich courses in earth science, atmospheric science, geology, meteorology, geomagnetism, and geophysics. Contains nearly 200 original illustrations and eight pages of full-color plates.* Largely mathematics-free and with a wide breadth of material suitable for general readers* Integrates material from geomagnetism, paleomagnetism, and solar-terrestrial space physics.* Features nearly 200 original illustrations and 4 pages of colour plates
