A quotation for today

HamiltonWilliam Rowan Hamilton (1805 - 1865)

I regard it as an inelegance, or imperfection, in quaternions, or rather in the state to which it has been hitherto unfolded, whenever it becomes or seems to become necessary to have recourse to x, y, z, etc...

Quoted in a letter from Tait to Cayley.

Another quotation by one of today's mathematicians.
