A Catechism of Familiar Things; Their History, and the Events Which Led to Their Discovery. With a Short Explanation of Some of the Principal Natural Phenomena. For the Use of Schools and Families. Enlarged and Revised Edition. Originally we had thirteen States, and thirteen only, but there was other territory here, and the attractive force of the successful union of the thirteen States brought the other territory in as it was organized. The New York Times Current History of the European War, Vol. 1, January 9, 1915 What Americans Say to Europe Laplace, in effect, has devoted a chapter of his splendid work to an examination of the oscillations which the attractive force of the moon is capable of producing in our atmosphere. Biographies of Distinguished Scientific Men The reciprocal transitions of freezing, condensation, and deposition are all exothermic processes, involving heat as intermolecular attractive forces are established or strengthened. Chemistry 2019-02-14T00:00:00Z If at any point in the solar system the attractive force is doubled, then according to our repulsive theory of heat, and the law of inverse squares, the repulsive motion is also doubled. Aether and Gravitation But here reality, no fantastic story, showed you men who, through the counteraction of attractive forces, could tell no difference between light substances and heavy substances, and who absolutely had no weight whatever themselves! All Around the Moon The attractive force of the moon is most strongly felt by those parts of the ocean over which she is vertical, and they are, consequently, drawn toward her. Scientific American Supplement, No. 620, November 19,1887 The contrary would happen on the occasion of the sudden birth of a planet; a certain time would elapse before the attractive force of the new body would make itself felt on the earth. Biographies of Distinguished Scientific Men The strong attractive force of one social stratum upon the next below, excites in the latter a nervous tension which predisposes to a breakdown in the face of some adversity. The Fertility of the Unfit Their experiments conclusively prove that light waves exert a pressure upon all bodies on which they fall, and by no reasoning can this pressure be resolved into an attractive force. Aether and Gravitation The attractive force will change its direction, and we shall land in the sun!� A Voyage in a Balloon (1852) It is the mutually attractive force that causes the heat and flame which accompany the combination; and this force is most violently active in the union of dissimilar substances. Lectures on Popular and Scientific Subjects In a mathematical point of view, the perturbation depending on the gradual propagation of the attractive force which this calculation indicates has a certain existence. Biographies of Distinguished Scientific Men The social status of one class exerts an attractive force on the class next below. The Fertility of the Unfit If the attractive force is halved, then the repulsive motion is halved also, the repulsive motion being always and at all places exactly proportional to the increase or decrease of the attraction of Gravitation. Aether and Gravitation Consequently, the 'attractive forces' of the bob and the earth are now acting against it, and constitute a resistance which the charge of kinetic energy has to overcome. The Advance of Science in the Last Half-Century The electric motor to be treated in this chapter illustrates very prettily the attractive force of a hollow, wire-wound bobbin on a movable core, when the electric current is passed through the wire. Things To Make That is to say, the attractive force of the highly developed Prussian State practically unified Germany for purposes of trade and commerce, and that, too, thirty-eight years before political union was achieved. The Development of the European Nations, 1870-1914 (5th ed.) The more unified this use of the fighting will of a people, the greater will be the magnetic attractive force of a movement and the more powerful the force of its push. Readings on Fascism and National Socialism Selected by members of the department of philosophy, University of Colorado Thus the great regulating principle of the attractive force of gravity is mass, and not volume, or density, or any other condition. Aether and Gravitation The last fraction of kinetic energy is just neutralised by the action of the attractive forces, and the bob has only potential energy equal to that with which it started. The Advance of Science in the Last Half-Century An attractive force is at this moment exerted between the metal and the oxygen of the liquid; actual combination, however, being in the first instance avoided. Six Lectures on Light Delivered In The United States In 1872-1873 Gravity, and indeed all the forms of the attractive forces, come under this head. Q. E. D., or New Light on the Doctrine of Creation The nearer you can actually see the thing as you wish it to happen, even to the general details, the stronger will be the attractive force thereof. Clairvoyance and Occult Powers As we have mentioned above, Schopenhauer's doctrines have exercised an attractive force in artistic circles also. History of Modern Philosophy From Nicolas of Cusa to the Present Time But here reality, by the neutralizations of attractive forces, produced men in whom nothing had any weight, and who weighed nothing themselves. From the Earth to the Moon; and, Round the Moon Be that as it may, Newton saw in Refraction the result of an attractive force exerted on the light-particles. Six Lectures on Light Delivered In The United States In 1872-1873 It is thus evident that the Earth must exert an overwhelming attractive force on all bodies on or near its surface. The Mastery of the Air It will now be of interest to consider the minor movements of the sun and moon, as they also affect the tides by reason of the alterations they cause in the attractive force. The Sewerage of Sea Coast Towns It has been seen that an electro-magnet exerts its attractive force in proportion to the current which passes through its coil. Steam, Steel and Electricity This is a process which might be repeated as soon as a new excess arose in the centrifugal over the attractive forces working in the parent mass. Vestiges of the Natural History of Creation It is the great attractive force of a small chance of a large gain, as compared with the deterrent force of a large chance of a small loss. Supply and Demand The bodily form of nature came to pass through the attractive force of the elements. Philosophical Letters of Frederich Schiller Some other element or elements may exert the whole attractive force which moves desire and will. A Handbook of Ethical Theory A wire through which a current is passing is always surrounded by a region of attractive force. Steam, Steel and Electricity While these remain exactly counterpoised, the mass necessarily continues entire; but the least excess of the centrifugal over the attractive force would be attended with the effect of separating the mass and its outer parts. Vestiges of the Natural History of Creation I have not left you in a spirit of retaliation; but simply because the natural strain of repulsion was stronger than all the attractive forces that held us together. The Hand but Not the Heart or, The Life-Trials of Jessie Loring It is also true that the attractive force within such a universe would be infinitely great in some direction or another. Side-Lights on Astronomy and Kindred Fields of Popular Science As the human meteoroid approached the sun or centre of attractive force, the attraction of one century squared itself to give the measure of attraction in the next. The Education of Henry Adams He also determined the ratio of the attractive forces of the sun and moon, which he found to be about as seven to three. A History of Science — Volume 3 This experiment succeeded so well that the string was lengthened until it was some two hundred and ninety-three feet long; and still the attractive force continued, apparently as strong as ever. A History of Science — Volume 2 First, the measure of gravity at its surface; this attractive force we know, by the increase of our own muscular force, must of course be considerably less than that at the surface of the earth. Off on a Comet! a Journey through Planetary Space A dynamic theory, assigning attractive force to opposing bodies in proportion to the law of mass, takes for granted that the forces of nature capture man. The Education of Henry Adams Motion is the ultimate object of science, and measures of motion are many; but with thought as with matter, the true measure is mass in its astronomic sense -- the sum or difference of attractive forces. The Education of Henry Adams For that, an attractive force was essential; a force from outside; a shaping influence. The Education of Henry Adams |
