Along the way, Birkeland made some remarkable discoveries and inventions, such as the idea of hearing aids for deaf patients of making caviar from cod roe and of using the force of cathode rays to propel rockets. He traveled across some of the most forbidding landscapes on Earth, from the ice mountains of Norway to the deserts of Africa, against a backdrop of war and political upheaval. At the age of thirty-one, Birkeland set out on a lifelong, increasingly compulsive quest to discover the origins of the aurora borealis. Now Lucy Jago tells the story of the science-and the romance-behind the Northern Lights as she traces the grand adventure of the life of the visionary Norwegian scientist Kristian Birkeland. Throughout the ages, the lights of the aurora borealis were believed to be messengers of gods, signs of apocalypse, or souls of the dead even the most sophisticated scientists misapprehended their cause.
