Richard Feynman is considered one of the fathers of nanotechnology. He did extensive work in atomic physics and made discoveries of the extremely small which he presented to the American Physical Society on December 29, 1959, at Caltech. The presentation title was, “There's Plenty of Room at the Bottom.” In this presentation, Feynman extended an invitation for scientists to begin manipulating and controlling things on a small scale, thereby entering a new world of physics. He proposed several concepts including writing at the nanoscale, building nanomachines and creating methods for fabrication, as well as storing digital information at the nanoscale. Feynman's presentation spurred the development of a new field of science called “nanoscience”.
