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.
Robert Coe, University of California, Santa Cruz

“Ronald Merrill skillfully weaves his professional expertise in geomagnetism with related scientific issues and personal anecdotes to create a broad intellectual tapestry that, in its many fascinating diversions and anecdotes, gives insight into how the mind actually works while exploring a question of abiding interest. Reading this book will be a learning experience for almost everyone—and an unfailingly pleasant one at that!”

Bruce Moskowitz, University of Minnesota

“Part science, part history of science, and part personal experience, Our Magnetic Earth seamlessly draws together a variety of seemingly unrelated topics—from climate to space weather to geologic time to the Sun—under the grand heading of magnetism. [Readers will be amazed to learn] just how much the field of magnetism has contributed to earth sciences and to our current understanding of our planet’s past, while they also enjoy the many wonderful anecdotes from working scientists with which Merrill sprinkles the book. Ultimately, we come away from this book understanding both much, much more about magnetism and about the importance of scientific literacy in today’s society.”

Julia Keller | Chicago Tribune

“If [you're looking for a gift for] a self-described geek drawn to science books like an iron filing to a magnet, then consider Our Magnetic Earth, a fascinating explanation of that mysterious force.”

Natural History

“Highly readable. . . . Merrill laces his narrative with discourses on the philosophy of science, and with ripostes to creationist attacks on evolution and the antiquity of Earth. I’ll recommend this book to students eager to know how science is done, and anyone wondering what makes a compass needle point north.”

Metascience
“There really is no other ‘popular’ book in recent years that covers the broad reach of geomagnetism as competently and as entertainingly as does this one.”
