"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bas-reliefs on curved surfaces, such as vases, or the frieze of a rotunda, where, by the curvature, the two ends are withdrawn from our sight, and where, while we advance, one object appears as another disappears.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 ...

... 'Wheeling round, like the planet Mercury in the curvature of its orbit, Jishnu (Arjuna) once more slew large number of the samsaptakas. Afflicted with the shafts of Partha, O king, men, steeds, and elephants, O Bharata, wavered and wandered and lost colour and fell down and died. Many foremost of animals tied to yokes and drivers ...

... Europe. 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 ...
