Mr. Tenniel is the only artist, who has drawn for me, who resolutely refused to use a model, and declared he has no more needed one than I should need a multiplication-table to work on a mathematical problem!

Quoted in M. N. Cohen & E. Wakeling, Lewis Carroll and His Illustrators (2003), p.247John Tenniel
We worked together for seven years. Tenniel and other artists declared I would not work with Carroll for seven weeks! I accepted the challenge, but I, for that purpose, adopted quite a new method. No artist is more matter-of-fact or businesslike than myself: to Carroll I was not Hy. F., but someone else, as he was someone else. I was wilful and erratic, bordering on insanity. We therefore got on splendidly.

Harry Furniss
If the system exhibits a structure which can be represented by a mathematical equivalent, called a mathematical model, and if the objective can be also so quantified, then some computational method may be evolved for choosing the best schedule of actions among alternatives. Such use of mathematical models is termed mathematical programming.
George Dantzig
I will not vote against the truths of the multiplication table.
