"Electro-magnetic" Quotes from Famous Books
 ... practical application for communication both between ship and ship and between ship and shore. Most transatlantic ships are now equipped with such a system. The transmitter consists of a large bell which is actuated either by compressed air or by an electro-magnetic system. This is so arranged that it may be suspended over the side of the ship and lowered well beneath the surface of the water. The receivers consist of microphones, one on each side of the ship. The telephone ...

... "express and admirable" than that of the most perfect machine or adaptation of natural forces yet devised. Lord Kelvin says the animal motor more closely resembles an electro-magnetic engine than a heat engine, but very probably the chemical forces in animals produce the external mechanical effects through electricity and do not act as ...

... this force is powerless to account for the spheroidal oblateness of certain planets. For if the bulge of planetary equators and the shortening of their polar axes is to be attributed to centrifugal force, instead of being simply the result of the powerful influence of solar electro-magnetic attraction, "balanced by concentric rectification of each planet's own gravitation achieved by rotation on its axis," to use an astronomer's phraseology (neither very clear nor correct, yet serving our purpose to show the many flaws in the system), why should there ...

... fundamental world than that of matter. This is the electro-magnetic world which underlies the material world and which, as Professor Soddy says, probably completely embraces it, and has no mechanical analogy. To those accustomed only to the grosser ideas of matter and its motions, says the British scientist, ...

... although of a much more complicated kind than the mechanical properties of tangible solid bodies. But neither Maxwell nor his followers succeeded in elaborating a mechanical model for the ether which might furnish a satisfactory mechanical interpretation of Maxwell's laws of the electro-magnetic field. The laws were clear and simple, the mechanical interpretations clumsy and contradictory. Almost imperceptibly the theoretical physicists adapted themselves to a situation which, from the standpoint of their mechanical programme, was very ...

... method a deep groove was cut around the wheel which was wound with a magnetizing coil. Thus one rim becomes a north and the other a south pole, and the rail completing the circuit acts as the armature. Such an arrangement prevents a wheel from sliding. Electro-magnetic adherence has also been employed to drive friction gear wheels. In one arrangement the two wheels are surrounded by a magnetizing coil, under whose induction each attracts the other, developing high adherence ...

... number of powers and privileges which previously had been impossible, but that step introduced no responsibility; we were no longer, indeed, urged by mere pressure from behind, we were guided by our instincts and appetites, but we still obeyed the strongest external motive, almost like electro-magnetic automata. Now, however, we have become conscious, able to look before and after, to learn consciously from the past, to strive strenuously towards the future; we have acquired a knowledge of good and evil, we can choose the one and reject the other, and are thus burdened with a sense ...

... beauty, of a Venus and a Diana combined. Her large, full, well turned neck and throat, fittingly supports a symmetrical, well poised head, of the same noble proportions. A long, thick, luxuriant growth of golden hair, brilliant with changing hues of a coppery tinge, seemingly so surcharged with electro-magnetic force, as to form a halo of sunshine around both face and head, is her chief personal adornment. Her large, oval face, well formed mouth, strong white teeth, firm chin, finely arched, strongly defined brows, broad, smooth forehead, and straight grecian nose; ...

... on Saturday his remains were interred in the burying ground in the neighborhood of that town known as the Old Aisle Cemetery. Mr. Bain, who was about sixty-six years of age, was a native of Thurso. He was the inventor of the electro-chemical printing telegraph, the electro-magnetic clock, and of perforated paper for automatic transmission of messages, and was author of a number of books and pamphlets relating to these subjects. Sir William Thomson, in his address to the Mathematical Section of the British ...

... ether as the medium of the transmission of light is one of these pretentious bridges of words. Our advancing knowledge of electro-magnetic phenomena may some day drive us back to a modified form of the corpuscular theory of light, and then we can throw this of the ether to the winds. In that case we would at least have a real material cause for the phenomena with which we deal. While the current theory of the ether ...

... ten or twelve telescopic comets; in the resolution of nebulae which had defied every thing in Europe but Lord Rosse's great reflector; in the application of electricity to the measurement of differences in longitude; in the ascertainment of the velocity of the electro-magnetic fluid, and its truly wonderful uses in recording astronomical observations. These are but a portion of the achievements of American astronomical science within fifteen or twenty years, and fully justify the most sanguine anticipations ...

... be, I wondered—how fixed, and what the source of their light? Products of electro-magnetic currents and born of the interpenetration of such streams flowing above us? Such a theory might account for their disappearance, and reappearance, shiftings of the flows that changed the light producing points of contact. Wireless lights? If so here was an idea that human science ...

... of Colonel Raslof (more recently the Danish Minister at Washington); the hospitalities of many of the principal citizens of Copenhagen; the visits to the tomb and museum of the works of Thorwaldsen, and to the room in which the immortal Oersted made his brilliant electro-magnetic discovery; the casual and accidental introduction and interview with a daughter of Oersted,—all created a train of reflection which prompted me to devise some suitable mode of showing to these hospitable people my appreciation of their friendly attentions, ...

... from what has been previously said on the subject of induction that the currents from such an electro-magnetic machine would be alternating currents, the impulses succeeding each other in alternate directions. To remedy this and cause the currents to flow always in the same direction, the "commutator" was devised. The ring mentioned above was split, and the ...

He struck out into the stream with the rest, and with overweening confidence in himself—in himself as master of circumstances which he intended to control ...

... lightnings that they may go and say unto thee: Here we are!" Said the Lord from the whirlwind to afflicted Job, who remained dumb for he could not answer. The question has been answered in the affirmative in our day by the perfector of the electro-magnetic telegraph, the late Professor Morse, by whose invention the promise has been fulfilled: "I'll put a girdle around the ...

... the increase of power is not merely in proportion to numbers. It grows in a much higher ratio. The effect is something like that of multiplying the surfaces in a galvanic battery, or increasing the coils in an electro-magnetic apparatus. Passion in a multitude becomes a tornado. Eloquence moves a large audience with a power vastly greater than when the listeners are few. Similar is that strange influence which fashion exerts ...
