'''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
