Dublin #

You best believe I made a stop in the city where I started my 6 week backpacking trip in 2016. Dublin! Another favorite. I wish I could live dozens of lives so I could truly soak in the beauty, history, and culture of every city on this trip. Not least of all, Dublin.

I stayed in an historic hotel that, with its winding halls and unpredictable layout, reminded me of “House of Leaves”. Fortunately, I didn’t get trapped.

Since I missed it in 2016 by about a couple hundred yards (facepalm), I made a more deliberate effort to seek out and visit the Quaternion plaque on Brougham (Broom) Bridge.

It says

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 i2 = j2 = k2 = ijk = −1 & cut it on a stone of this bridge.
