A nanoscale 8-bit adder operating in 50-by-50-by-50 nanometer dimension, put forth as part of the current Feynman Grand Prize challenge by the Foresight Institute, has not yet been achieved. However, ...

In 1959 renowned physicist Richard Feynman, in his talk “Plenty of Room at the Bottom,” spoke of a future in which tiny machines could perform huge feats. Like many forward-looking concepts, his ...

Electrical and computer engineers have developed a design for a functional nanoscale computing device. The concept involves a dense, three-dimensional circuit operating on an unconventional type of ...

And then, scientists and other creative thinkers began to realize Feynman’s nanotechnological visions. In the spirit of Feynman’s insight, and in response to the challenges he issued as a way to ...
