Nanotechnology and Fundamental
Transformation
Ed Regis, author of "Nano: the Energy
Science of Nanotechnology Remaking the World -
Molecule by Molecule," defines nanotechnology
as nothing less than 'the single biggest technological
advance in the history of the species." Building
with atoms will enable replacement of cells in
the body, manufacture of precious materials, molecular
robots, molecular computers, and the marriage
of DNA to materials.
Eventually, it will enable the manufacture of
anything, even at the consumer level. Nano means
billionths of: a nanosecond is a billionth of
a second, a nanometer is a billionth of a meter,
or the size of a molecule. We have now seen the
first successful demonstration of catalysis on
a nanometer scale. Achieving molecular synthesis
at this level represents an important step towards
attaining practical nanofabrication. Molecules
will be manipulated to make materials lighter,
stronger, more flexible.
At the quantum level, new states of matter
can be created. Conductors that are one atom wide
may change the nature of computing and energy
systems.
The compression of time into nanoseconds
is making 10ths and 100ths of a second seem slower,
and athletes not racing against each other but
against the clock are changing the entire
nature of many competitive sports, and even the
spectating experience.
When cameras are made smaller and smaller,
even potentially the size of a chip, snooping
becomes more ubiquitous, and surveillance moves
into even more private places.
Disks may store as many as 100 billion bits per
square inch, and perhaps move to where the recorded
area is at the atomic level. When the doubling
of chip power becomes no longer feasible (when
transistors in chips get down to 0.25 millionths
of a meter), we may have to switch to optical
and/or quantum computing. Smart cards may attain
the power of a computer and perform daily activities.
