Excerpt: ...can be made of them,) as soon as I had blown any of them them I cover'd it with a clear Glass, and by, that means its Colours emerged in a very regular order, like so many concentrick Rings encompassing the top of the Bubble. And as the Bub ble grew thinner by the continual subsiding of the Water, these Rings dilated flowly and overspread the whole Bubble, descending in order to the bottom of it, where they vanilh'd successively. In the mean while, after all the Colours were emerged at the top, there grew in thecenter of the Rings a small round black Spot, like that in the first observation, which continually dilated it self till it became sometimes more than £ or of an Inch in breadth before the Bubble broke. At first I thought there had been no Light reflected from.the Water in that place, but observing it more curiously, I saw within it several smaller round Spots, which appeared much blacker and darker than the rest, whereby I knew that there was some Reflexion at the other places which were not so dark as those Spots. And by farther Tryal I found that I could fee the Images, of some things (as of a Candle or the Sun) very faintly reflected, not only from the great black Spot, but also from the little darker Spots which were within it. Besides the aforesaid colour'd Rings there would often appear small Spots of Colours, ascending and descending up and down the sides of the Bubble, by reason of some Inequalities in the subsiding of the Water. And sometimes small black Spots generated at the fides would ascend ascend up to the larger black Spot at the top of the Bubble, and unite with it, Obs. 18. Because the Colours of these Bubbles were more extended and lively than theft of the Air thinn'd between two Glasses, and so more easy...

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).
