QuickTime Video

Length: 1m 17s
Size: 1.6 MB

Dr. Chris Muhlstein explains the challenge of studying materials that are too small to see with the naked eye. The technique some scientists use to observe individual atoms is similar to the technique of using touch to find out the size, shape, and location of objects in a dark room. By using a very small, sharp sensor, scientists can create an image of atoms.
