Vacuum   Listen
noun
Vacuum  n.  (pl. E. vacuums, L. vacua)  
1.
(Physics) A space entirely devoid of matter (called also, by way of distinction, absolute vacuum); hence, in a more general sense, a space, as the interior of a closed vessel, which has been exhausted to a high or the highest degree by an air pump or other artificial means; as, water boils at a reduced temperature in a vacuum.
2.
The condition of rarefaction, or reduction of pressure below that of the atmosphere, in a vessel, as the condenser of a steam engine, which is nearly exhausted of air or steam, etc.; as, a vacuum of 26 inches of mercury, or 13 pounds per square inch.
Vacuum brake, a kind of continuous brake operated by exhausting the air from some appliance under each car, and so causing the pressure of the atmosphere to apply the brakes.
Vacuum pan (Technol.), a kind of large closed metallic retort used in sugar making for boiling down sirup. It is so connected with an exhausting apparatus that a partial vacuum is formed within. This allows the evaporation and concentration to take place at a lower atmospheric pressure and hence also at a lower temperature, which largely obviates the danger of burning the sugar, and shortens the process.
Vacuum pump. Same as Pulsometer, 1.
Vacuum tube (Phys.),
(a)
a glass tube provided with platinum electrodes and exhausted, for the passage of the electrical discharge; a Geissler tube.
(a)
any tube used in electronic devices, containing a vacuum and used to control the flow of electrons in a circuit, as a vacuum diode, triode, tetrode, or pentode.
Vacuum valve, a safety valve opening inward to admit air to a vessel in which the pressure is less than that of the atmosphere, in order to prevent collapse.
Torricellian vacuum. See under Torricellian.

"Vacuum" Quotes from Famous Books



... belong to you. If I hold my breath for a moment wickedly (for I can't do it breathing), and try to look at the world with you out of it, I seem to have fallen over a precipice; or rather, the solid earth has slipped from under my feet, and I am off into vacuum. Then, as I take breath again for fear, my star swims up and clasps me, and shows me your face. O happy star this that I was born under, that moved with me and winked quiet prophecies at me all through my childhood, I not knowing what it meant:—the dear radiant thing naming ...

... the matron saw that we were interested, she asked if we didn't want to borrow No. 31 for a few days. She said they sometimes lent children for two weeks or so. When she said it, she sounded just as though a child were a typewriter or a vacuum cleaner, sent on ten days' free trial. I looked at Dad and Dad looked at me, and then he said, "We'll take her!" It didn't take long for the matron to do up her few clothes and to get her ready. She was so glad to make the loan that she hurried. Little ...

... loss of blood is to cause intense thirst. A quantity of liquid being taken out of the body. Nature seems to point out in this way that the loss should be supplied; you know she is said to abhor a vacuum. If he had had all his senses about him, he would merely have taken a sup and held it in his mouth some time before swallowing it; but he was half dazed, and did not know where he was, and he yielded to the instinct ...

... contraction, thus adding to the enlargement of the chest by increasing its depth. The abdominal muscles relax and allow the stomach, liver, and other organs in the abdomen to move downward to make room for the depressed diaphragm. This causes a vacuum in the chest. The lungs expand to fill this vacuum and the air rushes in ...

And for years afterwards, .. perhaps, ships shun the place; leaping over it as silly sheep leap over a vacuum, because their leader originally leaped there when a stick was held. There's your law of precedents; there's your utility of traditions; there's the story of your obstinate survival of old beliefs never bottomed on the earth, and now not even hovering in the air! There's orthodoxy! Thus, while ...

... times when the grief itself came uppermost; there were nights when she lay awake crying for her mother, when she was nothing but a bereft child in a vacuum of love. Her father's tenderness could not make up to her for the loss of her mother's. Very soon after her mother's death, his mercurial temperament jarred upon her. She could not understand how he could laugh and talk ...

... empty. A stable occupied all one side; the other three were formed by bunk houses and necessary out-buildings. Here, too, dwelt absolute solitude and absolute silence. It was uncanny, as though one walked in a vacuum. Everything was neat and shut up and whitewashed and apparently dead. There were no sounds or signs of occupancy. I was as much alone as though I had been in the middle of an ocean. My mind, by now abnormally sensitive and alert, leaped on this idea. For the same reason, it insisted—lack ...

... fashion." Such an illustration is worthless. The individual chosen does not fairly represent the class. If, on the other hand, a teacher in physics should announce that "all bodies fall at the same rate in a vacuum," and should illustrate by saying, "If I place a bullet and a feather in a tube from which the air has been exhausted, they will be found to fall equally fast," his example would be a fair one, as the two objects differ in no manner essential to the experiment ...

... on the bar and it was our business to keep the engines going at full speed until she was gradually urged over. At intervals she bumped. Some mass of rock or clay on which she rested would collapse and immediately the propeller would shove her a little further over. Our vacuum almost disappeared, for the injection pipe got blocked with mud. This meant more work for me in starting the ballast pump, and when that got choked too, I had to open it up and clean the valve-boxes. It ...

It's a wonder I didn't use up all the air on the island and create a vacuum—in which case the tiger would have blown up. I remember wondering what that big breath was going to do when it came out. I didn't know. I had no plan. I looked at the tiger and he looked at me and whined—like a spoiled spaniel asking for sugar. That was too much. I thought of Ivy, ...

... legal methods and the methods of diplomacy (in which I here include international conversations of every sort) is that the latter take place, as it were, in a vacuum.

The ideas of space and time are therefore no separate or distinct ideas, but merely those of the manner or order, in which objects exist: Or in other words, it is impossible to conceive either a vacuum and extension without matter, or a time, when there was no succession or change in any real existence. The intimate connexion betwixt these parts of our system is the reason why we shall examine together the objections, which have been urged against both of them, beginning with those ...

... process must take place in it which takes place at all. But let us suppose that cavities exist in this otherwise universal medium, as caverns exist in the earth, or cells in a Swiss cheese. In such a cavity there would be absolutely nothing. It would be such a vacuum as cannot be artificially produced; for if we pump the air from a receiver there remains the luminiferous ether. Through one of these cavities light could not pass, for there would be nothing to bear it. Sound could not come from it; nothing ...

The theory was advanced that, since his departure for the antarctic pole, the sun, by heating the southern hemisphere, had rarefied all its currents of air, elevated them, and left on the surface of that zone a vacuum, into which the currents of air of ours, which were lower on account of being more dense, were violently rushing.

Engines in which steam was used as a means of draining mines had long been in use; but the power relied on was mainly that of the weight of the air pressing on a piston beneath which a vacuum had been created by the condensation of steam; and the economical use of such engines was checked by the waste of fuel which resulted from the cooling of the cylinder at each condensation, and from the expenditure of heat in again raising it ...

Such feelings were the result of a void which the whole universe, as she thought, never could fill, but it was really a temporary vacuum, like that caused by the loss of a first tooth. These teeth come out with the first jar, and nature intends them to be speedily replaced by others, much more permanent; but children cry when they are pulled out, and fancy they are in very tight. ...

The principle of the old gardeners was that "Nature abhors a vacuum," and, as far as their gardens went, they did their best to prevent a vacuum occurring at any time. In this way I think they surpassed us in their practical gardening, for, even if they did not always succeed, it was surely something for them to aim ...

When the fish presses the soft edge of the disc against any smooth surface and depresses the ridges and the intervening spaces, a vacuum is formed, giving it enormous holding power. Other countries have sucker fish of different form; but it remained for the benighted Australian blacks, among a few other savage races, to make practical use of the ...

... distinctness with which you can see the objects. This consciousness of air in a picture of low horizon is a very difficult thing to describe and explain. We know when it is there and when it is not. It has to be seen, to be enjoyed, and recorded. Holbein painted Edward VI. standing, so to speak, in a vacuum. Every line of his face is sharply defined. In real life air softens all lines, so that even the edge of a nose in profile is not actually seen as a sharp outline. The figures in Richard II.'s picture stand in the most exhausted vacuum, ...

"Rhythm is the rule with Nature," said Tyndall; "she abhors uniformity more than she does a vacuum." So deep-rooted, in truth, is this principle, that we imagine it and feel it where it does not exist, as in the clicking of a typewriter.

The oval of the face and hair hung beside the fire with a dark vacuum for background. As if dazed by the glare, her green-blue eyes stared at the flames. Every muscle of her face was taut. There was something tragic in her thus staring—her ...

... should show wasteful expenditure; but all wastefulness is offensive to native taste. The psychological law has already been pointed out that all men—and women perhaps even in a higher degree abhor futility, whether of effort or of expenditure—much as Nature was once said to abhor a vacuum. But the principle of conspicuous waste requires an obviously futile expenditure; and the resulting conspicuous expensiveness of dress is therefore intrinsically ugly. Hence we find that in all ...

... objects of sense there is a third nature in which they are contained—that is to say, space, which may be explained in various ways. It is the element which surrounds them; it is the vacuum or void which they leave or occupy when passing from one portion of space to another. It might be described in the language of ancient philosophy, as 'the Not-being' of objects. It is a negative idea which in the course of ages has become positive. It is originally derived from ...

... percentages of the different impurities vary with the variation of the soils in which the cane is grown. The next step, following clarification, is evaporation, the boiling out of a large percentage of the water carried in the juice. For this purpose, a vacuum system is used, making possible a more rapid evaporation with a smaller expenditure of fuel. These two operations, clarification and evaporation by the use of the vacuum, are merely improved methods for doing, on a large scale, what was formerly done by boiling in pans or ...

The instant I inhale a fly it acts as an emetic. And if Nature abhors a vacuum, she, or at least my nature, abhors these wretches more, for the moment I swallow one a vacuum is instantly produced. Their bodies are full of poisonous matter, and they have a most disgusting flavour, though they taste sweet. They also cause great pains and discomfort to our eyes, which ...
