Like a set piece of fireworks, with its interdependent parts taking fire in turn, function after function, spectacle after spectacle, glittered, fizzed, and was extinguished, only to give place to newer and more splendid spectacles; separate circles, sets, and groups belonging to the social solar system whizzed, revolved, rotated, with edifying effects on everybody concerned, unconcerned, and not at all concerned; and at intervals, when for a moment or two something hung fire, the twinkle of similar spectacles sputtering away in distant cities beyond the horizon was faintly reflected in the social sky above the incandescent metropolis.
Arcot was smiling amusedly at his son. "I can't very well control this except by standing directly in front of it, but I suppose you know what you're doing." "Oh, this is a laboratory model, and I haven't gotten the thing into shape really. Look at the conductors that lead to the coil; they certainly aren't carrying ten K.W." Dr. Arcot slowly rotated the rheostat.
Faraday investigated these phenomena and soon discovered that a copper disc rotated below two magnet poles had electric currents generated in it, which flowed radially through the disc between its circumference and centre.
Some seem to rise out of a mist, as it were, and to become clearer. Others grow feebler. Some are split in two. Some are rotated through a right angle in a minute or less, although each of the grains may be the size of Great Britain. Generally they move together in groups of very various velocities, up to forty kilometres a second.
The vastness of all creation seemed still to revolve slowly about him. The monstrous globe which was Earth moved sedately from above his head to under his feet and continued the slow revolution. The Platform rotated in a clockwise direction. He was drifting very slowly away. "Chief," he said wrily, "you can't do worse than I'm doing, and we're rushed for time. You might come out. But listen!
Rob was bending over a curious-looking apparatus, consisting of a bent stick held in a bow-shape by a taut leather thong. The appliance was twisted about an upright piece of wood sharpened at one end which was rotated as the lad ran the bow back and forth across it.
Even perpetual motion became possible, and I was in a frame of mind prone to purchase Keeley- Motor stock from the first enterprising agent that landed on the Snark's deck. And when I discovered that the earth really rotated on its axis 366 times a year, while there were only 365 sunrises and sunsets, I was ready to doubt my own identity. This is the way of the sun.
Fernald, rubbing his hands with increasing satisfaction as one advantage of the arrangement after another rotated through his mind. "If only my father does not object," murmured Ted. "Object! Object!" blustered Grandfather Fernald. "And why, pray, should he object?" That a man of Mr.
The wheel B will cause the axis E to swing around on a horizontal plane, and this turning movement is always in a certain direction in relation to the turn of the wheel B, and it is obvious, therefore, that to make a gyroscope that will not move, or swing around an axis, the placing of two such wheels side by side, and rotated in opposite directions, will maintain them in a fixed position; this can also be accomplished by so mounting the two that one rotates on a plane at right angles to the other.
If, then, this stupendous sphere rotated once in twenty-four hours, the speed with which the movement of some of the stars must be executed would be so portentous as to seem well-nigh impossible. It would, therefore, seem much simpler on this ground to adopt the other alternative, and to suppose the diurnal movements were due to the rotation of the earth.
