Hamilton Commemorative Artwork

We wanted an artwork installation that would be a fitting tribute to William Rowan Hamilton ireland's greatest mathematician. The sculpture at Broombridge Luas stop is to commemorate Hamilton’s discovery of quarternion algebra.

On 16 October 1843 Irish mathematician William Rowan Hamilton and his wife Helen were walking along the banks of the Royal Canal from Dunsink Observatory to the Royal Irish Academy where he was President.

At Broome Bridge Hamilton had that very rare occurrence in science a Eureka moment. He suddenly alighted on the solution to a problem he had been working on for a long time and in his excitement, he took out his penknife and scratched his formula for Quaternion algebra onto the bridge: i² = j² = k² = ijk = −1  Quaternions would later be instrumental in putting the first man on the moon and be used for CGI in movies.

Quaternions are an extension of complex numbers, they describe the mechanics of rotations in three dimensional space. Hamilton had spent years looking for a three-dimensional number system. In a letter he wrote to one of his sons, he said that every morning his children would ask him “Well, Papa, can you multiply by triplets?” to which he was obliged to reply, with a shake of his head, “No, I cannot”. 

The sculpture re-enacts the story of his discovery, the moment of Hamilton’s “Eureka” revelation. As you follow the footsteps of Hamilton and his wife Helen walking towards the city centre, Hamilton’s come to a stop as the formula is revealed to him. The formula gradually appears illuminated in the pavement in his handwriting. It moves with the flow of the commuters who are traveling in the same direction as he was on that momentous day. Quaternions make it possible to understand the rotation of a 3D object in space. They can be found in simple everyday objects, from the rotation of your mobile phone’s screen to Quantum mechanics or computer gaming animation. 

The answer to a problem, big or small, can reveal itself in the quieter moments of calm contemplation.
