#Otd 1789: Work began on construction of the Royal Canal.
Fell into disrepair in late 20th C, but much has since been restored.
To the River Shannon was reopened on 1 October 2010, but the final spur branch of the canal to Longford Town remains closed. 🌊🦢

i² = j² = k² = ijk = −1
On 16 October 1843, walking along the Royal Canal in Dublin, William Rowan Hamilton realised that rotations in three dimensions need four numbers, not three. He carved the rule into Broom Bridge.
The price was commutativity: ij = k but ji = −k. Multiply around the cycle i → j → k and the sign is positive; go against it and it flips.
Today every 3D game engine and spacecraft attitude system rotates objects with q v q⁻¹.

Full time score
Great win for the minor hurlers v St Brigids earlier. Super performance from all the lads in front of a great crowd. Great to see the support of the senior hurlers on the sideline.
St Oliver Plunkett ER 1:14 (17)
St Brigids 0:15 (15)

Heute vor 183 Jahren, am 16. Oktober 1843, fiel dem irischen Mathematiker William Rowan Hamilton (* 4. August 1805 - † 2. September 1865) in einem Geistesblitz die Formel für Quaternionen ein und er ritzte sie in einen Stein der Broom Bridge in Dublin. de.wikipedia.org/wiki/Willia…

📢 #TalDíaComoHoy de 1843🗓️, William Rowan Hamilton concibe los cuaterniones, una extensión de los números complejos que no cumple la propiedad conmutativa. Anotó su fórmula en un puente de Dublín.

Today in 1843, William Rowan Hamilton was walking along Dublin's Royal Canal when, in "a flash of genius," the rule for multiplying quaternions came to him. He stopped on Broom Bridge and carved it straight into the stone: i^2 = j^2 = k^2 = ijk = -1, the first non-commutative algebra ever discovered.
Mathematicians still retrace his walk every October 16.
