When Munday was a graduate student at SEAS, he set out to measure this repulsive force with V. Adrian Parsegian, a senior investigator at the National Institutes of Health, and Federico Capasso, a professor of applied physics at SEAS...
...have two similar objects, like two dancers following steps, they tend to attract each other,” said Parsegian. “But with two unlike objects there is the possibility that they repel...
...prevents us from sticking to anything with an opposite charge is that all these forces have to be properly aligned before you can see them at work. "The materials are in motion, but sometimes the dance of the charges allows them to fall in step," says NIH physicist Adrian Parsegian, one of the authors of the paper. "When that happens, you get attractive forces...
...films of other materials. This increases efficiency, reduces friction and allows the hardware to be built to finer tolerances and tinier sizes. Design them small enough, and you can put them in microscopically tiny places machinery could never go before. "When you understand the forces you're manipulating," says Parsegian, "you can design efficiently at the nanometer scale...
...with last year's invisibility cloak, it doesn't portend magical applications in the everyday world - and won't for a long, long time. "If you're looking for a free trip for your body on quantum levitation, you're not going to get it with this," says Parsegian. Even at its most fanciful, physics, it seems, can play around for only so long before it gets back to serious work...
