Smith, of the Medical College, rotating round with Miss Clara Timms, their faces wearing that pained and anxious expression which the British countenance naturally assumes when dancing, giving the impression that the legs have suddenly burst forth in a festive mood, and have dragged the rest of the body into it very much against its will.
In the same year he invented his improved screw-lathe; and in the following year, at the request of the boroughreeve and constables of Manchester, he contrived an oscillating and rotating wet gas meter of a new kind, which enabled them to sell gas by measure.
To correct for these irregularities Copernicus introduced epicycle on epicycle in the lunar orbit. This is in its main features the system propounded by Copernicus. But attention must, to state the case fully, be drawn to two points to be found in his first and sixth books respectively. The first point relates to the seasons, and it shows a strange ignorance of the laws of rotating bodies.
They occur between the dark rings, the thicknesses to which they correspond being also intermediate between those of the dark ones. Take the case of the first bright ring. The thickness of the film is ½d; in this interval the rotating particle can perform only half a rotation.
Charlie Reynolds, the cool one, the most likely to succeed, waved jauntily and carelessly from his rotating, accelerating ring. Two-and-Two wagged both arms stiffly from his. Mitch Storey's bubb, lightest loaded, was jumping ahead. But you could hear him playing Old Man River on his mouth organ, inside his helmet.
They tell us that if such a ring be once formed on the minutest scale and set rotating, then, since it would be moving in pure ether and subject to no friction, it must according to all known laws of physics be indestructible and its motion perpetual.
Then, freakish firefly, there, it was off again, the prey of the nickum gusts, before ever a hand could touch it the black parachute rotating like a whirligig. Never oh, never was such a chase for such a prize since mountain was mountain and man was man!
The planets farthest from the sun would naturally not be so much affected by it. The same principle would explain the retrograde movement of the outer satellites of Saturn and Jupiter. Sir R. Ball further works out the principles on which the particles of the condensing nebula would tend to form a disk rotating on its central axis. The ring-theory of Laplace is practically abandoned.
I see that the sun still rises and sets to give the succession of day and of night, but the day and the night together only amounted to three hours, instead of twenty-four. Almost touching the chaotic mass of the earth is another much smaller and equally chaotic body. Around the earth I see this small body rapidly rotating, the two revolving together, as if they were bound by invisible bands.
Before it appeared in the realm of mechanics, experimenters were applying in the construction of flying models the knowledge supplied by Cayley in 1796, who made an instrument of whalebone, corks, and feathers, which by the action of two screws of quill feathers, rotating in opposite directions, would rise to the ceiling; and the full revelation of the structure and action of bird wings set forth by Pettigrew in 1867.
