The Physics Of Invisibility

The Physics of Invisibility

The ability is see is fundamental to our very existence. How true our perceptions really are depends upon many factors, and not least is our understanding of what light is and how it interacts with matter. It was said that the camera, the icon of light recording instruments, never lies, and in the day of the glass plate and celluloid roll-film this might well have been true. But in this modern era, with electronic cameras and computer software, it is often safe to assume that the camera always lies. The advertising images that bombard our every waking moment are manipulated in shape, profile, color, and form. In this new era, light can be manipulated with metamaterials to make one object look like another or even cause that objects to vanish, literally before our eyes; not only can the image we see be manipulated, but so can the light itself.

Invisible

Science is said to be on the verge of achieving the ancient dream of making objects invisible. Invisible is a biography of an idea, tied to the history of science over the "longue duree." Taking in Plato to today s science, Ball shows us that the stories we have told about invisibility are not in fact about technical capability but about power, sex, concealment, morality, and corruption. Precisely because they refer to matters that lie beyond our senses, unseen beings and worlds have long been a repository for hopes, fears, and suppressed desires. Ideas of invisibility are, like all ideas rooted in legend, ultimately parables about our own potential and weaknesses. Invisible presents the first comprehensive survey of the roles that the idea of invisibility has played throughout time and culture. This territory takes us from medieval grimoires to cutting-edge nanotechnology, from fairy tales to telecommunications, from camouflage to early cinematography, and from beliefs about ghosts to the dawn of nuclear physics and the discovery of dark energy. Invisible reveals what our age-old fantasies about what lurks unseen, and whether we can enter that realm ourselves, truly say about us. "
