That atoms really vibrate at the above rate per second is very certain, for their vibrations produce ether-waves the length of which may be accurately measured. When a tuning-fork vibrates 500 times a second, and the sound travels 1100 feet in the same interval, the length of each wave will be found by dividing the velocity in the air by the number of vibrations, or 1100 ÷ 500 = 2.2 feet.
Minuit, it was observed, never used a tuning-fork in church, like all leaders of religious music, but cast his eyes down a moment towards his heart, and tapped his foot, and then, as if catching the pitch somewhere from within, he raised the tune and carried it forward with an exquisite sense of rhythm.
Away wi' ye, schoolmaster, and take your tuning-fork to ask the blessing wi'. What says the Scripture, man? 'The living, the living, he shall praise Thee!" The doctor was a Scotchman, and Master Swift always listened with sympathy to a North countryman. He was convinced, too, and took his tuning-fork to the meals, and led the grace.
The memories began crowding in upon him now, and the baffling note upon which the mazurka had stopped short chimed like a tuning-fork in his ears. "I want to be a Greek myself, if you're one. I want to get as close to you to your ideal, that is, as I can. You open up to me a whole world that I had not even dreamed existed.
Marconi and several other workers in the field of wireless telegraphy are now busy experimenting on a system of attunement, or syntony, by which it will be possible to so adjust the sending instruments that none but the receiver for whom the message is meant can receive it. He is working on the principle whereby one tuning-fork, when set vibrating, will set another of the same pitch humming.
The prongs of a tuning-fork, vibrating 500 times per second, seem to be travelling very quickly, but are really only moving at the rate of 10 inches per second, or not much over half a mile per hour, when the amplitude is the hundredth part of an inch, which gives quite a loud sound.
The strong wind of His Father's love blew down through the wild mountains into His face, and made sweetest music, and His ear was in tune and heard it. He had a tuning-fork that gave Him the true pitch for the rarest music, while His feet travelled cautiously the deep wilderness ravines, and boldly climbed through the thorny undergrowth of that steep hill just outside the city wall.
It is a peculiar sound, not like the querulous buzz of the honey, nor the drone of the humble bee, but a sharp ringing resonance like that of a tuning-fork. Sometimes, in the far-away country where it is often much louder, the folk think it has a threatening note.
And instead of having a taste for being successful merchants and retiring at thirty, some people have a taste for high and what we call heroic forms of excitement. These are predestined; if a man love the labour of any trade, apart from any question of success or fame, the gods have called him. The incommunicable thrill of things, that is the tuning-fork by which we test the flatness of our art.
Then, turning to his assistant, "Apply that to the other wire," said he; and dropping his own wire, he put his hand over the cylinder, with his fingers dipping into the vessel from which the other wire sprang. When the wire hummed under the tuning-fork and the vibration thrilled again, instantly he felt as if an inert obstruction had been removed.
