A picture of me, under a Plaque celebrating William Rowan Hamilton's discovery of Quaternion. This was taken at the same time as the picture included in the Quaternions article.

I would appeciate it if you asked before using the image, at least the bit with me on. If you just want the bridge and plaque, then I have other images available, which don't have me on.
