While it was Clerk Maxwell who came up with the notion of nanotechnology, it was Richard Feynman in 1959 who spoke about the principles of nanotechnology. He described the concept of nanotechnology in his speech “There’s Plenty of Room at the Bottom”.  Feynman, in his speech, said he wanted to discuss “the problem of manipulating and controlling things on a small scale.” He wanted to store world’s books on “the barest of dust that can be made out by the human eye.” Feynman envisioned the manipulation of matter at the level of billionths of a meter. Richard Feynman will be remembered for popularizing the idea of nanotechnology to the rest of the world.
