Last week I busted out of the 2 km Lockdown restriction to walk alongside my local canal. It was nice to absorb the different and peaceful scenery. The Royal Canal flows from the River Liffey in Dublin to Longford in Ireland. In times past, the canals and river corridors of Ireland were traversed by pirates, saints, fishermen, pilgrims and soldiers. St Brendan the Navigator and raiding Viking parties utilised them too. The Lock Keeper’s of the canals have seen it all.
Irish waterways are a great way to explore Ireland. They provide a sense of history, peace and absolution, and are host to a wealth of wildlife in birds, plants and animals.
A railway line runs parallel to the Royal canal close to my home. It’s helped grow the economy of the country. A 20 minute train ride takes me into Dublin city center.
It was a controversial undertaking and constructed after the x-director of The Grand Canal Company stormed out of his board meeting saying he was going to construct another canal. It wasn’t properly surveyed and ran into enormous financial difficulties. It was completed using public funds.
I wonder if this sculptured Lock Keeper in Ashtown knows the formula to open up our coronavirus Lock down?
Water and lock keepers remove barriers. This open us to our history and ancestors. My friend Godfrey an Irish travel guide said:
“Back in the 1800’s William Rowan Hamilton a Professor of Mathematics worked out the Quantum Theorem formulas on a piece of stone from the Broom Bridge on the Royal Canal. His wife had to wait to finish their romantic walk on a bench. She might have been bored but her husband went down in history as the Father of Algebra.”
Here’s the bridge;
A plaque 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
i² = j² = k² = ijk = −1
& cut it on a stone of this bridge.
My friend Anne reminded me of “The Auld Triangle” Irish folk song about an Irishman in prison who misses his girl. It gives a nod to the banks of the Royal Canal. The link is below;
It takes emotional courage to follow the call to be still or to slow down during this pandemic. To see the unseen and hear the unheard. I love how it’s brought me face to face with local history.
This is blog 140. It lines up with (Math 140), the study of Math Algebra and the Auld Isosceles Triangle which has an angle that measures 140°.
