Hamilton Walk

Quaternion plaque on Brougham (Broom) Bridge, Dublin. Erected by the Dublin Institute for Advanced Studies (DIAS) in 1958.

The Hamilton Walk from Dunsink Observatory to Broom Bridge on the Royal Canal in Dublin takes place on 16 October each year. This is the anniversary of the day in 1843 when William Rowan Hamilton discovered the non-commutative algebraic system known as quaternions, while walking with his wife along the banks of the Royal Canal.[1][2]
