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 […]

2014 – Light Painting Acceleration

By mapping the output of a motion sensor to the hue of an LED strip (red for +2 G's along the Z-axis, and blue for -2) we can visualize the acceleration changes at the peaks and valleys, as the sensor is waved around. Source: Jake Ingman (@jingman), Data Painting
