Requirements: ePUB Reader, 617 KB
Overview: 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.
