The World's Largest Computer Bug is a Grain of Dust - Apparently.
In 1947, a single grain of dust jammed the Harvard Mark II computer's relay system, causing it to malfunction. The bug, which was later dubbed the "Harvard Bug," was discovered by Grace Hopper, a pioneering computer scientist. The dust grain had short-circuited a relay, causing the computer to produce incorrect results. Hopper's discovery led to the development of more reliable computer systems and the concept of debugging as we know it today.
