Over 2,000 years after the invention of the compass, Einstein called the source of Earth's magnetic field one of greatest unsolved mysteries of physics. Here, for the first time, is the complete history of the quest to understand Earth's magnetism--from the ancient Greeks' fascination with lodestone, to the geological discovery that the North Pole has not always been in the North--and to the astonishing modern conclusions that finally revealed the true source.
Richly illustrated and skillfully told, North Pole, South Pole unfolds the human story behind the science: that of the inquisitive, persevering, and often dissenting thinkers who unlocked the secrets at our planet's core.
