"Curvature" Quotes from Famous Books



... 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. Smaller willows are then interwoven, so ...

... account the ancients preferred for it such subjects as admitted of an indefinite extension, sacrificial processions, dances, and lines of combatants, &c. Hence they also exhibited bas-reliefs on curved surfaces, such as vases, or the frieze of a rotunda, where, by the curvature, the two ends are withdrawn from our sight, and where, while we advance, one object appears as another disappears. Reading Homer is very much like such a circuit; the present object alone arresting our attention, we lose sight of that which ...

... motion of a planet in its orbit. If we know the successive positions of the moving body at successive short intervals of time, the rules of the differential calculus enable us to calculate the speed, the change of speed, the change of direction of motion (i. e. the curvature of the path), and the effective force acting on the body. Conversely, given the force at every point, and the initial position and velocity, the rules of the integral calculus assist us in calculating the position and velocity ...

The nucleus presented to the naked eye a distinct disc of brilliant white light, from which the tail rose at an angle of about 30 deg. or 35 deg. with the horizon, curving slightly downwards, and terminating in a broad brush of faint light, the curvature of which diminished till it was nearly straight at the end. The portion of the tail next the comet appeared three or four tunes as bright as the most luminous portion of the milky way, and what struck me as a singular ...

Of course, the table is so small in proportion to the surface of the earth that the curvature is not appreciable, but it is nevertheless true in theory. A surface that we call level is not the same as our idea of a true ...

The bill also varies in length, width, depth, and curvature.

It was here in its perfection: it followed with winning obsequiousness every member, but delighted more especially to swim along that placid and pliant curvature on which Nature had ranged the implements of mastication. Pawing with his cloven hoof, he suddenly changed his countenance from the contemplative to the wrathful. At one effort he rose up to his whole length, breadth, and height: ...

The larger ones he secured with thread and the smaller with wax, and gave the whole a gentle curvature like the wings of a bird. Icarus, the boy, stood and looked on, sometimes running to gather up the feathers which the wind had blown away, and then handling the wax and working it over with his fingers, by his play impeding his father in his labors.

Rouen in the distance, with its ebony towers, fantastic roofs, and straggling suburbs, lines its shores, at a curvature where the stream swept away west again, bearing craft of the sea on its bosom.

The northern Indian snow-shoes differ a little from those of the southern Indians, having a greater curvature on the outside of each shoe; one advantage of which is, that when the foot rises the over-balanced side descends and throws off the snow.

Every joint of the stone is used, in like manner, as a thin black line, which the slightest sign of cement would spoil like a blot. And so proud is the builder of his fine jointing, ...

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 types of flying machine ...

This is "the mammoth," the remains of which are found in every river valley in England, France and Germany, and of which ...

When the desk is higher, it has been said the tendency is to elevate one shoulder, to depress the other, and to produce a permanent curvature of the spinal column. Although this may have been frequently the result of sitting at a high desk, yet it is not a necessary result. To prevent the projection of one shoulder, and the consequent spinal curvature, both of ...

By removing hairs from the tops of the ends, and from the bottom of the middle, he would be able to raise the arch of each eyebrow noticeably. This removal, along with the clearing of hair from the forehead, and thinning the eyelashes by plucking out, would ...

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."

And this applies equally both to permanent errors of curvature and to temporary distortions produced by strains and by inequality of temperature. The perfect achromatism of a reflector is, of course, a great advantage, but the chromatic aberration of refractors is now so well corrected that their inferiority in that respect may ...

... muscles, m, and it is by the action of these muscles that the lens is able to become small and thick, or large and thin; that is, to become more or less curved. When we look at near objects, the muscles act in such a way that the lens bulges out, and becomes thick in the middle and of the right curvature to focus the near object upon the screen. When we look at an object several hundred feet away, the muscles change their pull on the lens and flatten it until it is of the proper curvature for the new distance. The adjustment of the muscles is so quick and unconscious ...
