This blog has four themes as indicated by the acronym, RHIME. The header image features a graffiti mural (curated by Kathryn Maguire) celebrating the work of Irish mathematician William Rowan Hamilton (WRH, 1805-1865), located on the exterior wall of Croke Park in Dublin. It was launched on 21 April 2012 and survived in a public space for over four years before being defaced out of all recognition.
