|
* 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."
