Excerpt from On the Connection of the Physical SciencesIT has been proved by Newton, that a particle of mat ter (n. 6) placed without the surface of a hollow sphere (n. Is attracted by it in the same manner as if the mass of the hollow sphere, or the whole matter it con tains, were collected into one dense particle in its center. The same is therefore true of a solid sphere, which may be supposed to consist of an infinite number of concentric hollow spheres (n. This, however, is not the case with a spheroid (n. But the celestial bodies are so nearly spherical, and at such remote distances from one another, that they attract and are attracted as if each were condensed into a single particle situate in its center of gravity (n. 10) - a circumstance which greatly facili tates the investigation of their motions.Newton has shown that the force which retains the moon in her orbit, is the same with that which causes heavy substances to fall at the surface of the earth. If the eafth were a sphere, and at rest, a body would be equally attracted, that is, it would have the same wei ht at every point of its surface, because the surface 0 a sphere is everywhere equally distant from its center. But as our planet is ﬂattened at the poles (n. And bulges at the equator, the weight of the same body gradually decreases from the poles, where it is greatest, to the equator, where it is least. There is, however, a certain mean (n. 12) latitude (n. Or part of the earth intermediate between the pole and the equator, where the attraction of the earth on bodies at its surface is the same as if it were a sphere; and experience shows that bodies there fall through feet in a second. The mean distance (n. 14) of the moon from the earth is about sixty times the mean radius (n. 15) of the earth.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.

<p>As outspoken in his day as Richard Dawkins or Christopher Hitchens are today, American freethinker and author ROBERT GREEN INGERSOLL (1833-1899) was a notorious radical whose uncompromising views on religion and slavery (they were bad, in his opinion), women's suffrage (a good idea, he believed), and other contentious matters of his era made him a wildly popular orator and critic of 19th-century American culture and public life. As a speaker dedicated to expanding intellectual horizons and celebrating the value of skepticism, Ingersoll spoke frequently on such topics as atheism, freedom from the pressures of conformity, and the lives of philosophers who espoused such concepts. This collection of his most famous speeches includes the lectures: [ "The Gods" (1872) [ "Humboldt" (1869) [ "Thomas Paine" (1870) [ "Individuality" (1873) [ "Heretics and Heresies" (1874)</p>

Excerpt from On the Connexion of the Physical SciencesThe progress of modern science, especially within the last few years, has been remarkable for a tendency to simplify the laws of nature, and to unite detached branches by general principles. In some cases identity has been proved where there appeared to be nothing in common, as in the electric and magnetic influences in others, as that of light and heat, such analogies have been pointed out as to justify the expectation that they will ultimately be referred to the same agent: and in all there exists such a bond of union, that proficiency cannot be attained in any one without a knowledge of others.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
