Persistence of The Theory
Winer et al. (2002) have found recent evidence that as many as 50% of American college students believe in emission theory.
Modern computer graphics programs that use ray tracing often trace lines of sight from "eyes" to objects and thence to light sources to determine the colour and luminance of pixels in a simulated scene. This avoids the extra computation that would be required to trace rays which do not intersect with "eyes", and which by definition do not contribute to the simulated image.

Famous quotes containing the words persistence and/or theory:
“Nothing in the world can take the place of Persistence. Talent will not; nothing is more common than unsuccessful men with talent. Genius will not; unrewarded genius is almost a proverb. Education will not; the world is full of educated derelicts. Persistence and Determination alone are omnipotent. The slogan “Press On”, has solved and will always solve the problems of the human race.”
—Calvin Coolidge (1872–1933)
“The human species, according to the best theory I can form of it, is composed of two distinct races, the men who borrow and the men who lend.”
—Charles Lamb (1775–1834)
