Richard Feynman’s Tiny Machines

In 1959, physicist Richard Feynman, who had already done work that would win him the Nobel Prize a few years later, gave a talk at Caltech that didn’t have much to do with his main areas of study. The talk was called There’s Plenty of Room at the Bottom and it was a scientist at the peak of his formidable powers asking a question of the scientific community: What about nanotechnology?

I would like to describe a field, in which little has been done, but in which an enormous amount can be done in principle. This field is not quite the same as the others in that it will not tell us much of fundamental physics (in the sense of, “What are the strange particles?”) but it is more like solid-state physics in the sense that it might tell us much of great interest about the strange phenomena that occur in complex situations. Furthermore, a point that is most important is that it would have an enormous number of technical applications.

Even though he made no formal contribution to the field, Feynman’s talk has been credited with jumpstarting interest in the study of nanotechnology. No recording exists of the original talk, but in 1984, Feynman gave a talk he called Tiny Machines, in which he recalled his original talk and spoke of the progress that had been made over the past 25 years.
