Reaction, ``The Oscillatory Law of Human Progress. ``Joe'' Sheldon's ``Professorship of Horse Sense'' needed. First gift of a building McGraw Hall. Curious passage in a speech at the laying of its corner-stone. Military Instruction; peculiar clause regarding it in our Charter; our broad construction of it; my reasons for this.
Thus in 1903 it was found by Poulsen, elaborating on a principle first discovered by Duddell, that an oscillatory current may be derived from an electric arc maintained under certain conditions and that undamped high frequency waves so produced were suitable for wireless telegraphy.
For the tidal retardation is not an oscillatory change which will presently correct itself, like the orbital wobble, but a perpetual change, acting always in one direction. The exact character of these consequences was first estimated by Professor G. H. Darwin in 1879. He showed that tidal friction, in retarding the earth, must also push the moon out from the parent planet on a spiral orbit.
This cabinet became demoralised with amazing quickness; it became incontinent with its corruptions, a hinge got twisted, and after a time it acquired the habit of suddenly, and with an unpleasant oscillatory laughing noise, opening of its own accord and proclaiming its horrid secret to Euphemia's best visitors.
I then found that I could excite vacuum tubes at considerable distance from a conductor connected to a properly constructed coil, and that I could, by converting the oscillatory current of a condenser to a higher potential, establish electrostatic alternating fields which acted through the whole extent of a room, lighting up a tube no matter where it was held in space.
Thus the science of sound, which previously stood in the lowest rank of merely experimental science, became deductive when it was proved by experiment that every variety of sound was consequent on, and therefore a mark of, a distinct and definable variety of oscillatory motion among the particles of the transmitting medium.
Old Jolyon spoke; it was he who had started the discussion. "Four hundred fiddlesticks! Don't tell me you gave four hundred for that?" Between the points of his collar Swithin's chin made the second painful oscillatory movement of the evening. "Four-hundred-pounds, of English money; not a farthing less. I don't regret it. It's not common English it's genuine modern Italian!"
As a method of controlling and changing the rate of rotation of the wheel, the rivers of water had already proven themselves; and as a method of static balancing to compensate for off-center weights, masses of it could be stopped and held in counterbalance tanks around the rim, thus assuring that the observatory, in its stationary position on the hub, would not suddenly take up an oscillatory pattern of motion as the balance within the wheel was shifted either by moving equipment or personnel.
For producing the energy employed for transmitting the signals a high tension continuous current dynamo is used. An oscillatory current of high potential is produced in a circuit which consists of rapidly rotating disks in connection with the dynamo and suitable condensers.
Every sound, being a mark of a particular oscillatory motion, became a mark of every thing which, by the laws of dynamics, was known to be inferable from that motion; and every thing which by those same laws was a mark of any oscillatory motion among the particles of an elastic medium, became a mark of the corresponding sound.
