Description: Traces measurements from centimeters to atomic distances and shows how calibration of instruments can give an accurate knowledge of these measurements. Shows measuring techniques used with optical microscopes. Explains the principle of the use of electrons to cast shadows and how this is employed in the electron microscope. Dr. Edwin Mueller demonstrates his field emission microscope by which it is possible to see images of individual atoms, and he briefly discusses the principles involved in the microscope's operation.
