William Rowan Hamilton is a mathematician who had the insight of quaternions. Quaternions are useful in such calculations as satellite slews because they avoid the phenomena of gimbal lock. The moment occurred at Broom Bridge in Dublin, Ireland on October 16, 1843. There is a plaque the memorializes the moment. It reads:
Here as he walked by on the 16th of October 1843 Sir William Rowan Hamilton in a flash of genius discovered the fundamental formula for quaternion multiplication i² = j² = k² = ijk = −1 & cut it on a stone of this bridge.
