IBM 1620 data processing machine on display, Seattle World's Fair, 1962

Creator: Dudley, Roger


Description: The behavior of an elastic ball bounced on a hard surface is mathematically simulated by an IBM 1620 data processing system and visually traced by a CalComp digital plotter linked to the computer. This 'bouncing ball' problem is demonstrated daily in the 'Tools of Science' area of the U.S. Science Exhibit at the World's Fair.
