"Propulsion" Quotes from Famous Books
 ... matter how dimly, to perceive something of the causes which are at work. By the incoming of the European to inland China a transformation is being wrought, not the natural growth of a gradual evolution, itself the result of propulsion from within, but produced, on the contrary, by artificial means, in bitter conflict with inherent instincts, inherited traditions, innate tendencies, characteristics, and genius, racial and individual. In the eyes ...

... employed. For a marine governor to be of any use, it must not wait till the stern of the vessel is out of the water before it acts to check the engine and reduce the speed. Nothing but the most sensitive, and, indeed, anticipatory action of the governors can efficiently control marine propulsion. Instances are on record of vessels having engines without marine governors being detained by stress of weather at the mouth of the Thames, while vessels having such governors, of good design, have gone to Newcastle, have come back, and have found the other vessels ...

... primitive races, applying their wisdom and learning to the investigation of the origin of domestic and other implements and contrivances, inform us that the first boat was probably a log, on which the man sat astride, using a stick as a means of propulsion. In time the idea of hollowing the log occurred, Nature undoubtedly presenting the model and inviting the novice to squat inside. But what was the inhabitant of a certain island in the Gulf of Carpentaria to do since Nature failed to provide a tree big enough to ...

He mounted the seat, on his first essay alone, with the jauntiness becoming a master of vehicular propulsion.

For peaceful purposes, however, such a space mirror could be used to melt icebergs and alter temperatures."[14] Another reputable German scientist who has been working for a number of years on photon (electromagnetic ray) power as a source of propulsion, declares that if such power is possible so is "the idea of a 'death ray,' a weapon beam which burns or melts targets, such as enemy missiles, on which it is trained.

The bow, in straightening itself for the propulsion of the arrow, expends only the force which the man has imparted to it by bending it; so that the real power by which the arrow is propelled is, after all, the muscular strength of the archer. It is true, a great deal depends on the qualities of the ...

Its means of propulsion are two paddles, with which it also crawls along the bottom, and beneath which are situated the udders, with teats exactly like a cow's. Its flesh is far from bad, resembling lean beef in appearance, though hardly so good to the taste, and the skin can be manufactured ...

Our steamers consume 5 lbs. of coal per horse-power in one hour. And last, not least, one of the greatest improvements we have had in steam propulsion is the screw. Again, I may also name the great advantage derived from steam by our farmers in thrashing out grain. The engines principally used in farm-work are what are termed high-pressure, or of the same class as the locomotive. The great saving in cost in the first ...

The result was that, instead of falling immediately behind Bob, the fellow cannoned through the air a ...

Our plans were not carried out to such a stage of completeness as this when the strange sail hove in sight, and all our energies were now employed to get this part of the work done forthwith; as I felt convinced that, lying ...

But like most, if not all, compromise types, the galleass was short-lived. It was clumsy and slow, being neither one thing nor the other. Most of the time on the cruise these galleasses had to be towed in order to keep up with ...

With the electric engines used for submerged propulsion no longer available, and possibly the interior of the vessel in darkness, there were only two courses open. She could either rise to the surface and endeavour to fight it out with the aid of her powerful deck guns, or else sink to the bottom and trust to luck that other depth charges ...

As long as water, which is a non-exhaustive source of motion, was used, the people were scattered over the land; or if segregation took place, it was in the neighborhood of running streams. The application of steam to the propulsion of machinery, and the discovery of engines capable of competing with the human hand, led to the substitution of machine-made fabrics for clothing, in place of homespun articles of domestic manufacture. This led to the employment of farm-laborers in procuring ...

A little later we were able to be sure that what we saw was a kind of raft, with, as I have said, a mast and sail, but that its propulsion came from some human beings who were aboard it, and who were causing its slow progress with oars.

The French assert, that experiments in steam-propulsion were made on the Seine, by Count Auxiron and Perrier, in 1774, and on the Saone, by De Jouffroy, in 1782; but we know they led to no practical results, and the knowledge of them probably did not, for some years, travel beyond the limits of the French language. ...
