- * See http://www-groups.dcs.st-and.ac.uk/~history/Mathematicians/Hamilton.html
- * On 16 October 1843 (a Monday) Hamilton was walking in along the Royal
- * Canal with his wife to preside at a Council meeting of the Royal Irish
- * Academy.
- *
- * Although his wife talked to him now and again Hamilton hardly
- * heard, for the discovery of the quaternions, the first noncommutative
- * algebra to be studied, was taking shape in his mind:-
- *
- * "And here there dawned on me the notion that we must admit, in
- * some sense, a fourth dimension of space for the purpose of calculating
- * with triples ... An electric circuit seemed to close, and a spark
- * flashed forth."
