North Pole, South Pole: The Epic Quest to Solve the Great Mystery of Earth's Magnetism


Why do compass needles aspect north―but now not relatively north? What publications the migration of birds, whales, and fish around the world’s oceans? How is Earth capable of maintain existence less than an onslaught of sunlight wind and cosmic radiation? for hundreds of years, the world’s nice scientists have grappled with those questions, all rooted within the comparable phenomenon―Earth’s magnetism.

Over 2,000 years after the discovery of the compass, Einstein referred to as the resource of Earth’s magnetic box one in all maximum unsolved mysteries of physics. the following, for the 1st time, is the entire heritage of the hunt to appreciate Earth’s magnetism―from the traditional Greeks’ fascination with lodestone, to the geological discovery that the North Pole has no longer continually been within the North―and to the spectacular glossy conclusions that eventually printed the real source.

Richly illustrated and assuredly instructed, North Pole, South Pole unfolds the human tale in the back of the technological know-how: that of the inquisitive, persevering, and sometimes dissenting thinkers who unlocked the secrets and techniques at our planet’s core.
