nano-: pref. [SI: the next quantifier below micro-; meaning *
10^(-9)] Smaller than micro-, and used in the same rather loose
and connotative way. Thus, one has nanotechnology (coined by
hacker K. Eric Drexler) by analogy with `microtechnology'; and a few
machine architectures have a `nanocode' level below `microcode'.
Tom Duff at Bell Labs has also pointed out that "Pi seconds is a
nanocentury". See also quantifiers, pico-, nanoacre,
nanobot, nanocomputer, nanofortnight.
