If you could be invisible, what would you do? The chances are that it would have something to do with power, wealth or sex.
Perhaps all three. But there's no need to feel guilty. Impulses like these have always been at the heart of our fascination with invisibility: it points to realms beyond our senses, serves as a receptacle for fears and dreams, and hints at worlds where other rules apply.
Invisibility is a mighty power and a terrible curse, a sexual promise, a spiritual condition. This is a history of humanity's turbulent relationship with the invisible.
It takes on the myths and morals of Plato, the occult obsessions of the Middle Ages, the trickeries and illusions of stage magic, the auras and ethers of Victorian physics, military strategies to camouflage armies and ships and the discovery of invisibly small worlds. From the medieval to the cutting-edge, fairy tales to telecommunications, from beliefs about the supernatural to the discovery of dark energy, Philip Ball reveals the universe of the invisible.
