Publisher Description
The science and history of what lies between us and space: "I never knew air could be so interesting." —Bill Bryson, New York Times bestselling author of The Body: A Guide for Occupants
A flamboyant Renaissance Italian discovers how heavy our air really is (the air filling Carnegie Hall, for example, weighs seventy thousand pounds). A one-eyed barnstorming pilot finds a set of winds that constantly blow five miles above our heads. An impoverished American farmer figures out why hurricanes move in a circle by carving equations with his pitchfork on a barn door. A well-meaning inventor nearly destroys the ozone layer (he also came up with the idea of putting lead in gasoline). A reclusive mathematical genius predicts, thirty years before he's proven right, that the sky contains a layer of floating metal fed by the glowing tails of shooting stars.
We don't just live in the air; we live because of it. It's the most miraculous substance on earth, responsible for our food, our weather, our water, and our ability to hear. In this exuberant book, science writer Gabrielle Walker peels back the layers of our atmosphere with the stories of the people who have uncovered its secrets.
"A sense of wonder . . . animates Ms. Walker's high-spirited narrative and speeds it along like a fresh-blowing westerly." —The New York Times
"A fabulous introduction to the world above our heads." —Daily Mail on Sunday
"A lively history of scientists' and adventurers' exploration of this important and complex contributor to life on Earth . . . readers will find this informative book to be a breath of fresh air." —Publishers Weekly
PUBLISHERS WEEKLY
Most of the time we hardly notice that we're moving through air. But when a storm system whips it into a whirling mass that grows into a tornado or a hurricane, then the air around us makes headlines. Science consultant Walker (Snowball Earth) presents a lively history of scientists' and adventurers' exploration of this important and complex contributor to life on Earth, from Galileo's early attempts to show that it has weight to the explorations by 20th-century scientists Oliver Heaviside and Edward Appleton of the ionosphere, which acts as a giant mirror bouncing radio waves from one side of the globe to another. Walker provides readers with easy-to-follow discussions of the science behind the discovery that carbon dioxide levels are rising exponentially; the theoretician who left her computer for Antarctica and discovered a huge ozone hole created by chlorofluorocarbons; why hurricanes form only in the tropics and why global warming may lead to more violent storms. She goes far afield at times, spending too much time on the Van Allen belts, for instance, but readers will find this informative book to be a breath of fresh air.
