Though Isaac Newton's calculus and mechanical theory still holds firm after nearly 400 years of attempts to disprove them, about all that remains intact of Newton's theory of light is that sunlight is indeed a mixture of all the colors of the spectrum and can be split, as Newton demonstrated, into its separate physical components by means of a prism. Many still refer to him as the greatest scientist who ever lived, and the failure of his full theory of light to withstand the test of time and technological advances in investigative procedures and methods still does not detract from Newton's genius.
