Scientists Nearing Creation of Sound Cloak, Breaking Laws of Physics

While some work toward an invisibility cloak, University of Illinois professor Nicholas Fang is taking steps to create a similar material, only for sound, that could, for example, make ships invisible to SONAR. To successfully do this, of course, requires we break the laws of physics. But, you know, whatever. »5/30/09 11:15am5/30/09 11:15am
