1915 – Wire Models of Factory Worker Movements

3D wire models of hand motion paths (or chronocyclegraphs) created by Frank Gilbreth, a pioneer in the study of motion in the workplace. In his 1917 book, Gilbreth explains how he created these solid models from time-lapse photographs, and how useful they are to study and teach human motion. Left image: Wire model of foreman on drill press. This shows “positioning” in the midst of “transporting.” Right image: First photograph of wire models showing one man's progress of learning paths […]

1968 – Grace Hopper's Nanoseconds

Grace Hopper, a computer scientist and US Navy Rear Admiral, used wire to visualise very short durations of time in computing. Each wire is cut to the maximum distance that light or electricity can travel in a nanosecond, one billionth of a second. She wanted programmers to understand 'just what they're throwing away when they throw away a millisecond', and describes using them to help military commanders understand why signals take so long to relay via satellite. This lecture was given at MIT […]
