In order to consider in the most general way the principle of the production of motion by heat, it must be considered independently of any mechanism or any particular agent. It is necessary to establish principles applicable not only to steam engines but to all imaginable heat-engines , whatever the working substance and whatever the method by which it is operated.
When I landed in the republic of conscience it was so noiseless when the engines stopped I could hear a curlew high above the runway.
The essence of air transport is speed, and speed is unfortunately one of the most expensive commodities in the world, principally because of the disproportionate amount of the power required to achieve high speed and to lift loads thousands of feet into the air. This is strikingly illustrated by the fact that while an average cargo ship, freight train and transport aeroplane are each equipped with engines totalling about 2,500 H.P., the ship can carry a load of about 7,000 tons, the train 800 tons and the plane only two and a half tons.j. r. d. tata
Portland Tower, United 173, Mayday! We're . . . the engines are flaming out we're going down. We're not going to be able to make the airport.
Whenever our neighbour's house is on fire, it cannot be amiss for the engines to play a little on our own.Edmund Burke
Why has this silly engine suddenly turned up, which is so idiotically welded together? They told me then, there would be two engines connected behind each other, and suddenly there appears this misbegotten monster of welded-together engines one cannot get at!hermann göring
The idea of a terrorist attack that assaults innocent human beings in a building or a mall or a restaurant is bad enough. Yet the terrorist mind that looks at a passenger plane and sees the fuel and the intensity of the blast, and sees the rocket engines that will carry it into the heart of destruction like a cruise missile, but who does not see the humanity of one single soul on that airplane, is the chilling truth of what we're up against.alan keyes
This law (regarding the theoretical efficiency of heat engines by Mr. Joule), and the law of the maximum efficiency of heat engines, are particular cases of a general law which regulates all transformation of energy, and is the basis of the Science of Energetics.william john macquorn rankine
Changes in the structure of society are not brought about solely by massive engines of doctrine. The first flash of insight which persuades human beings to change their basic assumptions is usually contained in a few phrases.kenneth clark
While the body is young and fine, the soul blunders, but as the body grows old it attains its highest power. Again, every good soul uses mind; but no body can produce mind: for how should that which is without mind produce mind? Again, while the soul uses the body as an instrument, it is not in it; just as the engineer is not in his engines (although many engines move without being touched by any one).sallustius
More beautiful and soft than any moth
With burring furred antennae feeling its huge path
Through dusk, the air-liner with shut-off engines
Glides over suburbs and the sleeves set trailing tall
To point the wind. Gently, broadly, she falls,
Scarcely disturbing charted currents of air.
Besides the progress of industry and technique, we see a growing discontent among the masses; we see, besides the expansion ("expansion,", Fr.) of instruction, distrust and hatred expanding among nations ("s'étendre la méfiance et la haine entre," Fr.), that vie with one another ("qui rivalisent à l'envi," Fr.), by the increase of their armies and the improvement of their engines of murder ("engins meurtriers", Fr.).african spir
Pure mathematics , being mere tautology, and pure physics , being mere fact, could not have engendered them; for creatures to live, must sense the useful and the good; and engines to run must have energy available as work:;: and both, to endure, must regulate themselves. So it is to Thermodynamics and to its brother ?p log p , called Information theory, that we look for the distinctions between work and energy and between signal and noise.
First released in 2002, MediaWiki is one of the top wiki engines and runs most of the wiki hosting sites. The name was a play on “Wikimedia,” and many people find it to be annoyingly confusing.
MediaWiki (www.mediawiki.org/wiki/MediaWiki) is one of the best publishing wiki engines in existence.
Some wiki engines try to represent functionality that's more CMS-like (e.g. complex workflows and access controls), while MediaWiki's functionality tends to be driven by the needs of open communities with minimal barriers to entry.
To the art of mechanics is owing all sorts of instruments to work with, all engines of war, ships, bridges, mills, curious roofs and arches, stately theatres, columns, pendent galleries, and all other grand works in building. Also clocks, watches, jacks, chariots, carts and carriages, and even the wheel-barrow. Architecture, navigation, husbandry , and military affairs, owe their invention and use to this art.
The mechanical engineer is concerned with the generation and use of power, the design and development of a wide variety of products and machinery, and the operations and methods of manufacture . As such he engages in the design operation, and control of conventional and nuclear power plants. He designs and develops automobiles, engines, turbines, fluid machinery, production machinery, and equipment; heating, ventilating, air conditioning, refrigeration systems and equipment, appliances and other consumer goods.
Mechanical engineering may be defined as the manufacture, installation, and repair of all kinds of machinery (including machine tools), prime movers and boilers, and engines
The flames kindled on the 4th of July 1776, have spread over too much of the globe to be extinguished by the feeble engines of despotism; on the contrary, they will consume these engines and all who work them.
We do not copy Google's search results. We use multiple signals and approaches in ranking search results. Opt-in programs like the toolbar help us with clickstream data, one of many input signals we and other search engines use to help rank sites.
The towers themselves must be either round or polygonal. Square towers are sooner shattered by military engines, for the battering rams pound their angles to pieces but in the case of round towers they can do no harm being engaged as it were in driving wedges to their center.
The difference between "machines" and "engines" is obviously this, that machines need more workmen and greater power to make them take effect, as for instance ballistae and the beams of presses. engines, on the other hand, accomplish their purpose at the intelligent touch of a single workman,...
We have customers who build engines for aircraft. I am happy they are not using freeware when I get on a jet.

The switch from 'steam engines' to 'heat engines' signals the transition from engineering practice to theoretical science.hans christian von baeyer
