Nanostructures

Nobel Prize-winning physicist Richard Feynman is recognized as an early proponent of nanotechnology for his 1959 talk "There's Plenty of Room at the Bottom," in which he discussed the possibility of compressing machine engineering onto smaller and smaller scales. During his talk, he issued a challenge to engineers to create an electric motor smaller than 1/64th of an inch cubed. Read on for more images of nanostructures and the theories behind them.
