The best technical introduction to molecular nanotechnology: Nanosystems by K. Eric Drexler, Wiley 1992

The principles of physics, as far as I can see, do not speak against the possibility of maneuvering things atom by atom. It is not an attempt to violate any laws; it is something, in principle, that can be done; but in practice, it has not been done because we are too big. Richard Feynman, 1959

Today’s manufacturing methods move atoms in great thundering statistical herds
