"Cycloid" Quotes from Famous Books
 ... mathematical meditation. It was in the left hand try-pot of the Pequod, with the soapstone diligently circling round me, that I was first indirectly struck by the remarkable fact, that in geometry all bodies gliding along the cycloid, my soapstone for example, will descend from any point in precisely the same time. Removing the fire-board from the front of the try-works, the bare masonry of that side is exposed, penetrated by the two iron mouths of the ...

... opposite the sun. And it should be known that it is none other than that curve which is described by the point E on the circumference of the circle EB, when that circle is made to roll within another whose semi-diameter is ED and whose centre is D. So that it is a kind of Cycloid, of which, however, the points can ...

... curves; and passing lightly by the Conic Sections, the mathematicians of that day busied themselves in finding the areas, solids of revolution, tangents, etc., of all imaginable curves,—some of them remarkable enough. Such is the cycloid, first conceived by Galileo, and a stumbling-block and cause of contention among geometers long after he had left it, together with his system of the universe, undetermined. Descartes, Roberval, Pascal, became successively challengers or challenged ...

... which most probably belong, either to Pseudochromis or Assiculus, and which are to be placed, M. Valenciennes thinks, near Malacanthus, among the Labridae. Now, this family, according to M. Agassiz, is essentially cycloid in the structure of its scales, although there is a slight departure from the rigid characters of the order in the serrated preopercular of Crenilabrus, Ctenolabrus, and some others, and in the spine bearing operculum of Malacanthus. The latter genus is, moreover, described by M. Agassiz as ...

... a simple law from a circle, which has played an important part at various epochs in the intellectual history of our race. A spot on the tire of a wheel running on a straight, level road, will describe in the air a series of peculiar arches, called the cycloid. The law of its formation is simple; the law of its curvature is also simple. The path in which the spot moves curves exactly in proportion to its nearness to the lowest point of the wheel. By the simplicity of ...

... Mathematics," about a score of pages being devoted to his work. Much of his thinking was done while riding on horseback or in the rude vehicles of the day on the missions to which he was sent as Papal Legate. He is said to have worked out the formula for the cycloid curve while watching the path described by flies that had lighted on the wheels of his carriage, and were carried forward and around by them. His scientific books, though they included such startling anticipations ...
