"Curvature" Quotes from Famous Books



... charming effects which artists term "aerial perspective," by which relative distances are rendered cognisable with such tender and exquisite beauty. The absence of atmosphere on the Moon causes the most distant objects to appear as close as the nearest; while the comparatively rapid curvature of the moon, owing to its being a globe only one-fourth the diameter of the earth, must necessarily limit very considerably the range ...

... and Curved Fire.—"High angle fire," as defined officially, "is fire at elevations greater than 15deg," and "curved fire is fire from howitzers at all angles of elevation not exceeding 15deg." In these cases the curvature of the trajectory becomes considerable, and the formulae employed in direct fire must be modified; the method generally employed is due to Colonel Siacci of ...

... sees tears trembling on the lower lashes of her grey eyes, but something has come into the features, some irradiation of love—is it the light of the sunset?—which imparts a tender youthfulness to the curvature of cheek, lips and chin. Her face, indeed, might be of any age: it held the undying beauty of a goddess, in whom knowledge has sweetened to tenderness and divinity has dissolved in a need for compassion; and the youthful assurance of a happy woman whose wish ...

Planes of the former type are generally fitted to racing aeroplanes, because they offer less resistance to the air than do deeply-cambered planes. Indeed, it is in the degree of camber that the various ...

It is a well known truth that, if an artificial star is placed in the exact center of curvature of a truly spherical mirror, and an eyepiece be used to examine the image close beside the source of light, the star will be sharply defined, and will bear very high magnification. If the eyepiece is now drawn toward the observer, the star disk begins to expand; and if ...

I carefully examined the bed of the sea off the Santa Cruz, and found that its inclination was exactly the same, both in amount and in its peculiar curvature, with that of the 355 feet plain at this same place. If, therefore, the coast, with the bed of the adjoining sea, were now suddenly elevated one or two hundred feet, an inland line of cliffs, that is an escarpment, would be formed, with a gravel-capped plain at its ...

... "whiteness is that whereby a thing is white." Accordingly in defining an accident in the abstract, we do not put the subject as though it were the first part of the definition, viz. the genus; but we give it the second place, which is that of the difference; thus we say that simitas is "a curvature of the nose." But if we take accidents in the concrete, the relation begins in the subject and terminates in the concrete, the relation begins in the subject and terminates at the accident: for "a white thing" is "something that has whiteness." Accordingly in defining this ...

I noticed, too, that Davies spoke with a zest, sinister to me, of the delights of ...

... Some are mere cartilage for a considerable time. This is the case with the bones of the back. Now every person must see that the weight of the child's head and shoulders, resting for a considerable time on the slender cartilaginous spinal column, may easily bend it. And a curvature, thus given, may, and often ...

... among the lot, evidently the leader of them, who bore a close resemblance to the so-called Neanderthal man of La Chapelle-aux-Saints. There was the same short, stocky trunk upon which rested an enormous head habitually bent forward into the same curvature as the back, the arms shorter than the legs, and the lower leg considerably shorter than that of modern man, the knees bent forward and never straightened. This creature and one or two others who appeared to be ...

... horse as they neared an open bluff where the beetling rocks jutted out like a promontory above the sea of foliage below. They might judge of the long curvature of the conformation of the range just here, for on the opposite height was visible at intervals the road they had traveled, winding in and out among the trees, ascending the mountain in serpentine coils; they beheld the Cove beneath from a new angle, and further yet the barren ...

... that point. The next step was in learning that this image can be viewed with a microscope, and magnified; thus came the telescope revealing unheard of suns and galaxies. The first telescopes colored everything looked at, but by a hundred years of mathematical research, the proper curvature of objectives formed of two glasses was discovered, so that now we have perfect instruments. Great results followed; one can now peer into the profound solitudes of space, bringing to view millions of stars, requiring light 5,000 years to traverse their awful distance, ...

Early in the style they are plain and square-edged; late in the style they are often found enriched with the zig-zag and roll mouldings, or some other ornament. Sometimes the curvature of the arch does not immediately spring from the capital or impost, ...

It follows, therefore, that the general curvature at the bottom of these amphitheatres gives us fear of an inferior diameter to ...

... barrels. Still, she is an attractive woman, having the ruddy complexion of an unlicked postage stamp and the go-as-you-please features of a Turkish carpet. Her eyes are a trifle too ferrety, but the osculatory power of her mouth in auld lang syne must have been such as to give Cupid spinal curvature. Her nose retreats somewhat precipitately from the chasm; but whether that be its original pattern, or it has been gradually forced upwards by eager pilgrims to her shrine of adjustable pearls, is a secret hidden in her own heart. Like ...

... the ends turned up and secured by a lariat; willow rods of the required dimensions are then cut, heated, and bent into the proper shape for knees, after which their centres are placed at equal distances upon the keel, and firmly tied with cords. The knees are retained in their proper curvature by cords around the ends. After a sufficient number of them have been placed upon the keel, two poles of suitable dimensions are heated, bent around the ends for a gunwale, and firmly lashed to each knee. ...

The outline between these points is convex, but so slightly so that the curve departs at the point of greatest curvature not more than 3/4 in. from the straight line joining the top and bottom. This is, however, just sufficient to correct the tendency to look hollow in ...

... man is always man in every acceptation of the word. In every case in which the bones collected have enabled us to judge, he has ever been found to have the hand and foot proper to our species, and that double curvature of the spinal column has been made out, so characteristic that Serres made it the distinctive attribute of his human kingdom. In every case with him, as with us, the skull is more fully developed than the face. In the Neanderthal skull ...

He was to suggest trying on various types of hat and to show by his manner and bearing, but without any coarse flattery, the enhanced impression made by the hats he wished to sell. He had several mirrors, adapted by various subtleties of curvature and tint to different types of face and complexion, and much depended on the ...

... other than those of Euclid. In these geometries the sum of the angles of a triangle is not two right angles, and the departure from two right angles increases as the size of the triangle increases. It is often said that in non-Euclidean geometry space has a curvature, but this way of stating the matter is misleading, since it seems to imply a fourth dimension, which is ...

Not a few of such braces and supporters are seriously dangerous. A good brace, well-fitting, carefully adjusted, suited to the particular case, is often of excellent service; but the majority of them do ...

Then he binds those in the middle with thread, and the lowermost ones with wax; and, thus ranged, with a gentle curvature, he bends them, so as to imitate real {wings of} birds. His son Icarus stands together with him; and, ignorant that he is handling {the source of} danger to himself, with a smiling countenance, he sometimes ...

The inflected and capricious edges of the rocks stood out in high relief against the back-ground of pearly sky, resembling so much ebony wrought into every fantastic curvature that a wild and vivid fancy could conceive.

... has long been observed that school children are more subject to curvature of the spine and other deformities of the skeleton than the children who do not attend school. While this is due largely to faulty positions assumed by the pupils at their work, it has been suggested that the school furniture may be in part to blame for these positions. ...

... bronze worker took an earlier Buddhistic form of vase and gave it a new grace that amounted almost to artifice. A parallel might be found among the products of the so-called art nouveau of to-day, in which old designs are revived with just that added suavity or profusion of curvature that robs them of character. Fig. 16 again might be mistaken almost for a piece of the Chow dynasty, were not the grandeur of its form modified by just so much harmony in the curvature of the body and neck, and by just so much finish in the details as to rob the design ...

... question, how far the development of Ligia is repeated in the other Isopoda, I can only give an unsatisfactory answer. The curvature of the embryo upwards instead of downwards was met with by me as well as by Rathke in Idothea, and likewise in Cassidina, Philoscia, Tanais, and the Bopyridae,—indeed, I failed to find it in none of the Isopoda examined for this purpose. In Cassidina also the ...

Her neck rose from the withers to the head in perfect curvature, hard, devoid of fat, and well cut up under the chops. Her nostrils were full, very full, and thin almost as parchment. The eyes, from which tears might fall or fire flash, were well brought out, soft as a gazelle's, almost human in their intelligence, while over the small bony head, ...
