    Opticks or a Treatise of the Reflections, Refracections, and Colours of Light []  2020-1-19 20:13

    Sir Isaac Newton (1643-1727) was an English physicist, mathematician, whose Principia (published in 1687) founded classical mechanics, and described universal gravitation and the three laws of motion. His most popular work is The Principia.He begins this 1704 book by stating, "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: In order to which I shall premise the following Definitions and Axioms." (Pg. 1)After an experiment with prisms, he observes, "we find... that when the Rays which differ in Refrangibility are separated from one another, and any one Sort of them is considered apart, the Colour of the Light which they compose cannot be changed by any Refraction or Reflexion whatever, as it ought to be were Colours nothing else than Modifications of Light caused by Refractions, and Reflexions, and Shadows. This Unchangeableness of Colour I am now to describe…” (Pg. 121)He observes, “all the Productions and Appearances of Colours in the Globe are derived, not from any physical Change caused in Light by Refraction or Reflexion, but only from the different Mixtures or Separations of rays, by virtue of their various Refrangibility or Reflexibility. And in this respect the Science of Colours becomes a Speculation as truly mathematical as any other part of Opticks. I mean, so far as they depend on the Nature of Light, and are not produced or altered by the Power of Imagination, or by striking or pressing the Eye.” (Pg. 244)He points out, “Now the smallest Particles of Matter may cohere by the strongest Attractions, and compose bigger Particles of weaker Virtue; and a lot of of these may cohere and compose bigger Particles whose virtue is still weaker, and so on for divers Successions, until the Progression end in the largest Particles on which the Operations in Chymistry, and the Colours of natural Bodies depend, and which by cohering compose bodies of a sensible Magnitude.” (Pg. 394)He concludes, “Now by the support of these Principles, all material Things seem to have been composed of the hard and solid Particles above-mentioned, variously associated in the first Creation by the Counsel of an smart Agent. For it became him who made them to set them in order. And if he did so, it’s unphilosophical to seek for any other Origin of the World, or to pretend that it might arise out of a Chaos by the mere Laws of Nature; though being once formed, it may continue by those Laws for a lot of Ages. For while Comets move in very excentrick Orbs in all manner of Positions, blind Fate could never create all the Planets move one and the same method in Orbs excentrick, some inconsiderable Irregularities excepted, which may have arisen from mutual Actions of Comets and Planets upon one another, and which will be apt to increase, till this System wants a Reformation. Such a unbelievable Uniformity in the Planetary System must be allowed the Result of Choice.” (Pg. 402)This book will be of keen interest to students of the history of science.

    It's awesome to have as an interesting historical resource, but it's definitely like a dry math book. This edition does have diagrams though.

    If you wish to read something by Newton, obtain the Principia. Whoever translated this book did a horrible job.

    Although some of the back cover reviewers talk about this being one of Newton's most accessible works; it is still a tough read. However, if you wish to understand how a amazing mind struggles with complex issues, light and its behavior, this is a book worth working with. His experiments are fascinating and I am in awe of the effort he must have place in to not only design and execute the experiments but to deal with the volume of calculations he had to perform to reach the level of accuracy that he does.

    I am amazed at the shear number and info of the a lot of experiments Newton performed on light. His conclusions drawn from these rather easy experiments are astounding.
