Description:

Scientists at the University of Science and Technology of China use images of carbon-60 molecules made with a scanning tunneling microscope (STM) to determine the orientation of the molecules (buckyballs) sitting on a silicon surface.  Buckyballs are large hollow "soccerball-like" molecules made up carbon atoms.  The image on the left is the image actually taken by the STM of the buckyball, and can be compared to the computer calculation of what the image is expected to be on the right.
