How to Become Invisible
mdm42 writes "Looks like a theoretical physicist at St. Andrews University in Scotland believes that invisibility may be possible. And its not going to be a potion or a cloak, but will come in the form of a device. " Let's just hope that when the invisible woman arrives, she's played more convincingly than Jessica Alba.
true invisibility is impossible
Not really. It can be done and probably will be done some day. It is just not as simple or work the same way bad sci-fi shows portray it.
and even if it was possible, we'd be blind while we were invisible.
Yes, but this is a solvable problem as well. Bend visible wavelengths of light around, but not infrared and wear infrared goggles. Or bend light around everywhere except a pinhole too small to be visible, but which is used to generate a view outside the cloak like a pinhole camera does. Or transmit an image from a small device outside the cloak. The hard part is redirecting the light properly. Once that is solved, the rest is a lesser problem.
