Excerpt: ... which can continue long in one and the same part of a Body, can be propagated a long way from one part to another, supposing the Body homogeneal, so that the Motion may not be reflected, refracted, interrupted or disorder'd by,.j any unevenness of the Body. (gu 13. Do not several sorts of Rays make Vibrations of several bignesses, which according to their bignesses excite Sensations of several Colours much after the manner that the Vibrations of the Air, according to their several bignesses excite Sensations of several sounds? And particularly do not the most refrangible Rays excite the shortest Vibrations for making a Sen-. sation of deep violet, the least refrangible the largest for making a Sensation of deep red, and the several intermediate sorts of Rays, Vibrations of several intermediate bignesses to make Sensations of the several intermediate Colours? §u. 14. May not the harmony and discord of Colours arise from the proportions of the Vibrations propagated through the Fibres of the optick Nerves into the Brain, as the harmony and discord of Sounds arise from the proportions of the Vibrations of the Air? For some Colours, if they be view'd together, are agreeable to one another, as those of Gold and Indigo, and others disagree. Ght. if. Are not the Species of Objects seen with both Eyes united where the optick Nerves meet before they come into the Brain, the Fibres on the right side of both Nerves uniting there, and after union going thence into the Brain in the Nerve which is on the right side of the the Head, and the Fibres on the left side of both Nerves uniting in the fame place, and after union going into the Brain in the Nerve which is on the left side of the Head, and these two Nerves meeting in the Brain in such a man cond of Time befor...

From the Back Cover:
Sir Isaac Newton begins the Opticks, his 1704 study of the nature of light and color, by outlining its purpose: "My Design in this Book is not to explain the Properties of Light by Hypotheses, but to propose and prove them by Reason and Experiments." The Opticks is largely a record of these experiments and the deductions made from them, rather than a series of equations, and as a result, it was to prove heavily influential among lay readers, who found it easier to follow than its predecessor, the dense and heavily mathematic Principia.
About the Author:
Yet while the Principia may be regarded as Newton's magnum opus, the Opticks on its own would have been enough to earn him a reputation as a scientist for the ages. Though the field has advanced in the many years since, the Opticks remains essential reading for the scientific historian and budding physical scientist.
English physicist and mathematician SIR ISAAC NEWTON (1642-1727) is widely regarded to be the foremost figure in the history of science. Among his numerous contributions to science and mathematics, he is credited with the development of calculus, but is perhaps best known for discovering the universality of gravitation after witnessing a falling apple.
His most famous work is Philosophiae Naturalis Principia Mathematica (1687).
