Okay, this isn’t really a how-to item, but it may be one day, if a Scottish theoretical physicist has his way. Dr. Ulf Leonhardt, of St. Andrews University in Scotland, believes that invisibility is possible via the optical technique of bending light around an object (such as you in a cape and a spandex suit):
“Leonhardt uses the example of water circling around a stone. The water flows in, swirls around the stone and then leaves as if nothing was there. ‘If you replace the water with light then you would not see that there was something present because the light is guided around the person or object. You would see the light coming from the scenery behind as if there was nothing in front,” he said.”
Dr. Leonhardt describes the physics behind the theoretical devices that could create such invisibility in the current New Journal of Physics. It is a follow-up to an earlier study he published in the journal Science
