|Among all the studies of natural causes and reasons Light chiefly delights the beholder; and among the great features of Mathematics the certainty of its demonstrations is what preeminently (tends to) elevate the mind of the investigator.
||Perspective, therefore, must be preferred to all the discourses and systems of human learning. In this branch of science the beam of light is explained on those methods of demonstration which form the glory not so much of Mathematics as of Physics and are graced with the flowers of both.
~ Leonardo da Vinci
Design is a Process as well as the end result.
