Abstract:
Now Dr. Culpepper is figuring out how to make machines that build tiny things made up of moving parts as small as atoms and molecules. He calls these "super-precise machines," as they need to be able to pick up something as small as a molecule and position it precisely into place.
This is called "nanotechnology," the science of developing materials at the atomic and molecular level. Imagine a very powerful computer so tiny you can't see it without a microscope.
