Sir William Rowan Hamilton LL.D, DCL, MRIA, FRAS was an Irish mathematician, astronomer, and physicist. He was the Andrews Professor of Astronomy at Trinity College Dublin, and a director at Dunsink Observatory. He made major contributions to optics, classical mechanics and abstract algebra. His work was of importance to theoretical physics, particularly his reformulation of Newtonian mechanics, now called Hamiltonian mechanics. It is now central both to electromagnetism and to quantum mechanics. In pure mathematics, he is best known as the inventor of quaternions.
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.
Time is said to have only one dimension, and space to have three dimensions. ...

And how the One of Time, of Space the Three, Might in the Chain of Symbols girdled be.
Who would not rather have the fame of Archimedes than that of his conqueror Marcellus?
