These rules are of use only in correcting the figures; since every man makes some mistakes in his first compositions and he who knows them not, cannot amend them. But you, knowing your errors, will correct your works and where you find mistakes amend them, and remember never to fall into them again. But if you try to apply these rules in composition you will never make an end, and will produce confusion in your works.

...Conversation should be like juggling; up go the balls and the plates, up and over, in and out, good solid objects that glitter in the footlights and fall with a bang if you miss them. But when dear Sebastian speaks it is like a little sphere of soapsud drifting off the end of an old clay pipe, anywhere, full of rainbow light for a second and then - phut! vanished, with nothing left at all, nothing.
Evelyn Waugh
Geometry is of much assistance in architecture, and in particular it teaches us the use of the rule and compasses, by which especially we acquire readiness in making plans for buildings in their grounds, and rightly apply the square, the level, and the plummet. By means of optics the light in buildings can be drawn from fixed quarters of the sky. Difficult questions involving symmetry are solved by means of geometrical theories and methods.
Vitruvius
I do not know if you remember the tale of the girl who saves the ship under mutiny by sitting on the powder barrel with her lighted torch and all the time knowing that it is empty This has seemed to me a charming image of the women of my time. There they were, keeping the world in order by sitting on the mystery of life, and knowing themselves that there was no mystery.
Karen Blixen
A great part of its theories derives an additional charm from the peculiarity that important propositions, with the impress of simplicity on them, are often easily discovered by induction, and yet are of so profound a character that we cannot find the demonstrations till after many vain attempts; and even then, when we do succeed, it is often by some tedious and artificial process, while the simple methods may long remain concealed.
Carl Friedrich Gauss
A good deal of my research in physics has consisted in not setting out to solve some particular problem, but simply examining mathematical equations of a kind that physicists use and trying to fit them together in an interesting way, regardless of any application that the work may have. It is simply a search for pretty mathematics. It may turn out later to have an application. Then one has good luck. At age 78.
