Scott Hubbard is the director of NASA's Ames Research Center in Silicon Valley, NASA's lead center on nanotechnology. Not surprisingly, he has a particularly clear view of the nano/bio/info convergence: "The three, on their own, have important implications. To put the three of them together, the way I think about it, is that we are informed by biology of what nature has learned how to do over several billion years at the molecular level. It then gives us the capability to simulate that in computer modeling. And the nanotechnology allows us to actually manipulate physical materials to mimic, in some cases, what nature has done."
