"Concave" Quotes from Famous Books



... of artificialities; for they are a part of a horticultural whole. To walk into a Japanese garden is like wandering of a sudden into one of those strange worlds we see reflected in the polished surface of a concave mirror, where all but the observer himself is transformed into a fantastic miniature of the reality. In that quaint fairyland diminutive rivers flow gracefully under tiny trees, past mole-hill mountains, till they fall at last into lilliputian lakes, almost smothered for the flowers that ...

... less false, more and more nearly true "ideas" about the phenomenon. The "ideas" are reflexes of the phenomenon, reflected in our midst as in a mirror; the reflexes may be distorted, as in a convex or concave mirror, but they suggest an ideal reflex valid in infinity. It is of the utmost importance to realize that the words which are used to express the ideas and the ideals are THE MATERIALIZATION of the ideas and ideal; it is only by words that we are enabled to give to other human beings ...

... focus. If, however, the supposed plane surface proves to be convex, the image will not be sharply defined in the telescope until the eyepiece is moved away from the object glass; while if the converse is the case, and the supposed plane is concave, the eyepiece must now be moved toward the objective in order to obtain a sharp image, and the amount of convexity or concavity may be known by the change in the focal plane. If the surface has periodic or irregular errors, no sharp image can be obtained, ...

... isochronism of the pendulum, followed by Huyghens's adaptation of that principle to clocks, has been one of the greatest aids to accurate observation. About the same time an equally beneficial step was the employment of the telescope as a pointer; not the Galilean with concave eye-piece, but with a magnifying glass to examine the focal image, at which also a fixed mark could be placed. Kepler was the first to suggest this. Gascoigne was the first to use it. Huyghens used a metal strip of variable width in the focus, as ...

... schemes ready to try, and one of them was successful. Singularly enough it was not the same plan as the Dutch optician's: it was another mode of achieving the same end. He took an old small organ-pipe, jammed a suitably chosen spectacle glass into either end, one convex, the other concave, and, behold! he had the half of a wretchedly bad opera-glass capable of magnifying three times. It was better than the Dutchman's, however: it did ...

... already grown cool; snow had appeared on the mountain peaks; the basin was no longer a great green bowl, but resembled a mammoth, concave palette upon which nature had mixed her colors—yellow and gold and brown, with here and there a blotch of red and purple, a dash of green,—lingering over the season—and great, wide stretches of gray. The barren spots seemed to grow more barren—mocked by ...

... gleamed a lump of yellow metal, which I took to be gold. Hall and I were seated near another table about twenty-five feet distant from the tube, and on this table was an apparatus furnished with a concave mirror, whose optical axis was directed towards the tube. It occurred to me at once that this apparatus would be suitable for experimenting with electric waves. Wires ran from it to the floor, and in the cellar beneath was audible the beating of an engine. My companion ...

... Leyden-jars, eudiometers, thermometric scales, philosophical instruments, were distributed through the chambers. The third story, save two bed-chambers,—one for the housekeeper, the other for the footman,—had been fitted up for an observatory. The lenses and achromatic glasses, tubes and specula, concave mirrors, and object-prisms, and the huge, rough old telescope, peering through the roof, were still there as their owner had left them. All appliances of housekeeping were absent, and Cavendish House was destitute of all comforts, for which the owner ...

... natural verdure, bright or dark as deciduous or evergreen trees preponderate. The variety of form is endless; long ridges, high peaks, sharp or blunt, sudden clefts, great bare slides, flowing curves, convex or concave, serrated slopes crowned with dark spruce or jagged as the naked vertebrae of some enormous antediluvian monster, stimulate the curiosity and excite the imagination of the beholder. There is an essential difference in the character of the views obtained, whether looking from the south, ...

... adopted her niece, from whom she received all the attention and watchful tenderness which she needed continually, by reason of age and manifold infirmities. But while our life has its outer convex side, which magnifies its advantages before the world, it has its inner concave side also, which reduces the outer circumstances of prosperity into littleness, when "the heart knoweth its own bitterness, and a stranger doth not intermeddle with its joy." So it was with Mary Stansfield. She had a refined and luxurious ...

Horses lay stark across the way, or, dying, stared with piteous eyes. The sky was like a bowl of brass, and in the concave buzzards were sailing. All along there was underfoot much of soldiers' impedimenta—knapsacks, belts, accoutrements of all kinds, rolled blankets and oilcloths, canteens. Dead men did not lack. They lay in strange postures, and on all the dust was ...

These gases had not yet been seen collected in the static condition at the bottom of a tube and separated from their vapors by the clearly defined concave surface which is called a meniscus.

That part of the skee under the foot is concave, and here it is thickest, so that where it supports the weight of the person it cannot bend downward. The under part of the skee is grooved and polished, and soon becomes by use as smooth as glass. The forward end turns slightly upward, as you see by the pictures, so as ...

... quadrants are excited with opposite electricities, as when connected with the opposite poles of an insulated galvanic cell, the needle is repelled by one pair and attracted by the other, and therefore rotates through an arc of greater or less extent. A small concave mirror is attached above the needle and its image is reflected on a graduated screen. This makes the smallest movement visible. Sometimes the quadrants are double, forming almost a complete box, ...

It was lighted by one narrow, high, Gothic window, the panes of which were very small, lozenged, and many of them still stained. The roof was groined and concave, and still gay with tarnished gold. The mouldings and traceries sprang up from the four corners, and all terminated in the centre, in which grinned a Medusa's head, with her circling snakes, in high preservation, and of great and ghastly beauty.

It arises from the rays of the sun thrown on the concave and convex surfaces of the dew-drops, each particle furnishing a double reflection.

The further off the dew-drops are from the eye the more brilliant do they appear, and ...

... was little more than a lake of mud. The same facts were brought out at the bend of the river. On its convex side, Fig. 55, the water has rather further to go in getting round the bend than on its concave side B, it therefore flows more quickly, and carries away the soil of the bank and mud from the bottom. But on its concave aide where it flows more slowly it deposits material. There is at the bend a marked difference in depth at the two sides. ...

As he rode abstractedly forward under the low cottonwood vault he felt a strange influence stealing over him, an influence that was not only a present experience but at the same time a far-off memory.

He noticed how the bottom of a vessel containing water appears to rise more and more away from the vertical, and at once jumped to the analogy of a concave mirror, which magnifies the image, while a convex mirror was likened to a rarer medium. This line of attack also failed him, as did various attempts to find relations between his measurements of refraction and conic sections, and he broke off suddenly with a ...
