Have a Happy "Hamilton Day"

 April 15-23, 2016 is Maths Week in Ireland.

 

     AND, as this recent Slate article by Katharine Merow announces, in Ireland October 16 is "Hamilton Day" -- named for Irish mathematician William Rowan Hamilton (1805-1865).  Math-science writer Merow entertainingly describes Hamilton's mathematical contributions and suggests that the holiday be celebrated by more of us than just Ireland. 
     This blog adds some poetry to the celebratory fare -- here is a link (from a 2011 posting) to a poem by Hamilton, himself and this January, 2016 link leads to a sonnet about Hamilton by poet Iggy McGovern.
