Journey from the center of the Earth to the edge of the cosmos in this book of amazing, little-known facts about the universe. It's not science fiction, it's the planet Earth. This book will give you a world of information about the planets, volcanoes, glaciers, water, and more!
From the first great experimental scientist: the classic text, first published in Latin in 1600. Summarizes then-current knowledge of magnetism and electricity, offering insights into the origins of modern science.
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.
Explore the fascinating field of magnetism with this interactive picture book for young learners. Magnetism is all around us--even the earth is a giant magnet. A world without magnets would be a world without cell phones, computers, and more! Trusted children's nonfiction author David A. Adler covers the basics of magnetism, including compasses, for aspiring scientists. Hands-on experiments are smartly woven into the narrative. Want to test out the strength of a magnet? All you need is a bowl of water and some paper clips! Anna Raff's lively art illustrates scientific concepts clearly, with the added fun of two siblings and their dog exploring and learning together. Back matter includes a glossary that defines such terms as attraction, pole, electromagnetism, force, and more. Suggested activities on how to make your own magnet are also included.

Predicting changes and trends for the future, this fascinating exploration debunks the myths surrounding 2012 to provide a logical and spiritual theory. Wild claims and bad astronomy have fuelled a doomsday sensation about that energetic and special year, yet little or none is mentioned about the key planets sending the messages—Pluto, Chiron, Cere, Makemake, Eris, and Sedna, as well as some newly discovered planets. This resource delves deep into these important astrological beings to reveal what will really happen in 2012 and how the gods and goddess of these planets will help humanity navigate financial, social, and physical revolutions. Part history, scientific theory, and spiritual insight, this cutting-edge contention provides an understanding not only of 2012 but also of the transformations that will follow.
Describes what electricity is and how it is generated, stored, and used; explains what magnets are and how magnetism works; and discusses how electricity can be used to create magnets.
With the awareness that the Earth has a magnetic field, its mathematical description, discovery of remanent magnetisation in rocks and discovery of the periodic reversals of the geomagnetic field polarity, geomagnetism within geophysics became an interesting field of study. This is primarily due to advances in measurement technology and improved understanding of the magnetic field and its fluctuations in the geospace. Several important aspects of solid Earth geomagnetism are elaborated in the book. The first six chapters cover the basics of magnetism, magnetic minerals, biomagnetics, instrumentation and the behavior of geomagnetic field, while the rest of the book is devoted to practical applications with carefully selected examples and illustrations. Well-written and easy to read, the book vividly describes modern techniques in the subject matter covered, adequately supported by graphical explanations for complex mathematical concepts.
