It should be noted that fishing with any live bait should be condemned for the same reason as fishing with a worm: in all those cases, we tortured two animals at once for our amusement.
Proposition IX. Radiant light consists of ripples of the luminiferous ether.
Bacon first taught the world the true method of the study of nature, and rescued the science of that barbarism in which the followers of Aristotle, by an overly slavish imitation of their teacher.
Newton advanced, with a gigantic step, from the regions of twilight at noon of science. A Boyle and a Hooke, who otherwise would have deserved the boast of their century, served only as obscure precursors of the glories of Newton.
The nature of light is a matter of no material importance for the concerns of life or the practice of the arts, but in many other aspects it is extremely interesting.

Another class of ancient and extensive languages, united by a large number of similarities that may well be totally accidental, can be called Indo-European, including the Indian, West Asia and almost all European languages.
Suppose that several equal waves of water move over the surface of a stagnant lake, with a certain constant velocity, and enter a narrow channel that leaves the lake.

Neither of the two series will destroy the other, but their effects will be combined.
Vision motivates, sustains and dispels doubt.
