Outside of yoga class, we don’t pay too much attention to the air we take in every day. Long one of the essential elements to life on earth—from the atmospheric composition that gave life to the coal-forming forests some three hundred million years ago to the air that fuels our most important technologies today—we think little of its incredible properties. In this innovative cultural and scientific history, Peter Adey takes stock of the great ocean of air that surrounds us, exploring our attempts to understand, engineer, make sense of, and find meaning in it.
 
Adey examines how humans have managed and manipulated air as a natural resource and, in doing so, have been taken to the limits of survival, brought to high-altitude mountain peaks, subterranean worlds, and the troughs of new moral depths. Going beyond how vital air has been to our philosophical, scientific, and technological pursuits, he also reveals the way that the artistic and literary imagination has been lifted through air and how, in air, cultures have learned to express and inspire each other. Combining established figures such as Joseph Priestley, John Scott Haldane, and Marie Curie with unlikely individuals from painting, literature, and poetry, this richly illustrated book unlocks new perspectives into the science and culture of this pervasive but unnoticed substance.

Light as a feather, stiff as a board, light as a feather, stiff as board: anyone who has ever been to a slumber party can probably still conjure these words from deep within their psyche. Sure, anyone can fly these days so long as they have a credit card and government-issued ID, but what does it take to perform that more fundamental magic, to levitate? In this fascinating book, Peter Adey hovers over the peculiar stories of those who have dreamed of, believed in, or—can you believe your eyes—practiced levitation, offering a wide-ranging history of a unique phenomenon that can be found in countless cultures.
           
As Adey argues, levitation is best thought of as a pre- or parallel pursuit to that of aviation—but one that doesn’t cheat by employing aeronautical machinery. As he shows, many people have been certain that it is absolutely possible to float unaided. Early modern scientists believed in the force of levity as an opposite to that of gravity. Many traditional societies have deep-rooted shamanic traditions of spirit and dream flight. And many ancient religions have age-old accounts of ascetic saints hovering in sublime ecstasy. In more recent times, magicians and mesmerists have wowed audiences by seeming to float by the powers of thought alone. Science-fiction writers and urban planners alike have countless designs of floating cities hovering high above the earth, and even artists have experimented with levitation to find new forms of expression—one need just think of Yves Klein’s “Leap into the Void.”
           
Touching upon these and many other examples, Adey demonstrates how significant this magical act has been in our cultural, scientific, and spiritual lives. From poetry to philosophy to technology to even law, he lifts up levitation as a fascinating wonder in our shared imaginations.
