"As an undergrad, I studied engineering physics at the University of Oklahoma, and all my degrees are..." — Paul McEuen

I remember being fascinated by ants and wasps and other bugs when I was a kid. I'd set out a Coke can and stand back 20 feet and use my telescope to watch wasps land on it.

The lessons learned as we try to build ever more sophisticated nanomachines will almost certainly inform our understanding of the origins of life.

It's amazing that something only an atom thick can be an impenetrable barrier. You can have gas on one side and vacuum or liquid on the other, and with a wall only one atom thick, nothing would go through it.

Nanotechnology is the idea that we can create devices and machines all the way down to the nanometer scale, which is a billionth of a meter, about half the width of a human DNA molecule.
