Their dance kept step with the vibrations which surged up from Lee's chest into his brain and started racing through his consciousness around and around, forming a vortex which swept up his thoughts like wilted leaves.
When a current of electricity reaches a place in the conductor where it cannot pass easily, and the orderly vibrations of its molecules are disturbed, they are thrown into the disorderly motion known as heat.
The result is that the movements that are caused in the first diaphragm by the voice, are caused in the second by an attraction that varies in strength in proportion to the vibrations of the voice speaking against the first diaphragm.
A steady flow from a battery is passed through an instrument which throws this current into propervibrations by stopping the flow of the current at each interval between impulses.

The theory of electrical vibrations is explained elsewhere as the only tenable one by which to account for electrical action.
The slower vibrations to which I have referred reveal the bewildering possibility of telegraphy without wires, posts, cables, or any of our present costly appliances.
The ear is constructed on the same principle, its diaphragm being actually moved by the vibrations of air, being what we call hearing.
In the action of fire the vibrations are irregular and spasmodic; in electricity they are controlled by a certain rhythm or regularity.

There is no means of reproducing the volume of the voice with the minute vibrations of a little iron disc.
Light vibrations were present in ether long before the animal by responding to them made them any part of its own true environment.
It is quite as probable that they here serve as organs for feeling the slightestvibrations in the surrounding water, and thus giving warning of approaching food or danger.
Footnote 271: Jaimini maintains that the vibrationsof the air "manifest" the always existing sound.
Although many of these did not cause a sensible shaking over areas exceeding a few hundred square miles, many of them were sufficiently intense to propagate vibrations round and through the globe.
Although the maximum displacement has a definite direction, the successive vibrations are frequently performed in many different azimuths.
Such vibrations may be damped out to a considerable extent by the use of a dash-pot, or may be practically prevented by using a relatively stiff spring.

Mildly it flowed through the neighboring regions of the heavens, it flashed and showered softly, and in gentle vibrations extended through vast spaces.
In 1739 Euler reckoned the vibrations of the great eight-foot C to be one hundred and eighteen to the second.
As the singer interprets the song the vibrations set up by the singer’s voice are communicated to the diaphragm by the passage of the sound through the horn.
In the early Edison phonograph the sound vibrations were registered on a tinfoil-covered cylinder.
Marconi’s system is based on the property supposed to be exerted by the vibrations or waves of electric currents passing through a wire of setting up similar vibrations in the ether of space.
These indentations correspond to the vibrations imparted to the needle through the diaphragm, and are the recorded sounds made by the singer or band.
Who can say that their unknown inhabitants do not think of us in their turn, and that Space may not be traversed by waves of thought, as it is by the vibrations of light and universal gravitation?
Reversing the process, beautiful flashes of light have been produced from musical vibrations by the phonophote of M.
The very slightest vibrations communicated to the wood are heard distinctly in the telephone.
The isochronism of the vibrations of the pendulum inferred from this observation was not published or put to practical application in clocks for nearly sixty years afterward.
In this experiment the wrong box was indicated by the buzzing sound of the apparatus and the slight vibrations which resulted from it.
Through many long gleebs, our people have lived a semi-terrorized existence while errant vibrations from this world ripped across the closely joined vibration flux, whose individual fluctuations make up our sentient population.
For this purpose I must utilize the feeble vibrations of various not-people through whose inadequate articulation I will attempt to make my moves known to you.
My process--original with myself, by the way--is to send out feeler vibrations for what these people call the psychic individual.
You never mentioned it in any of your vibrations to us, gleebs ago, when you first came across to this world.
Quickly, from the not-world vibrations about you, I learned the not-knowledge of your location.
In short, the instrument may be explained as one invented to transmit air vibrations by electricity.
The rod vibrates with every passage of the current, and the thin box increases the amount of these vibrations and makes them audible.
In either case, however, the vibrations of the rod are exactly the same as those of the membrane, and even the character of the sound is automatically reproduced.
Like the tone of a fine old Cremona violin, its softest vibrations make themselves heard and understood when mere noise makes only confusion.
Great interest in telegraphic subjects has lately been aroused in the American public by exhibitions of the telephone, an instrument for transmitting sound vibrations by electricity.
Has the law of ethereal vibrations undergone any recent changes to debar or molest the communion of the soul with its spiritual father, any more than it has debarred contact with its material mother or environments?
I tell you frankly, if I were in charge here, I'd let the vibrations go to Hell and begin pumping lead.
The emperor-moth calls its mate--so says Fabre--by means of olfactory vibrations totally uncomprehended by us.
Some of the so-called lower animals take cognizance of vibrations that mean nothing to us.
Autenreith mentions the vibrations of a loud noise tickling the fauces to such an extent as to provoke vomiting.
I visited the plants where ultronic vibrations were isolated from the ether and through slow processes built up into sub-electronic, electronic and atomic forms into the two great synthetic elements, ultron and inertron.
The chest discs were likewise self-contained sending sets, strapped to the chest a few inches below the neck and actuated by the vibrations from the vocal cords through the body tissues.
But the same motives which made her transfer her inference from consequences to conditions are the motives which lead others to inferring from sounds to vibrations of air.
If she turns out to be in error, it is not because sound ought to mean so many vibrations of the air, and as matter of fact doesn't even suggest air vibrations, but because there is wrong inference as to the act to be performed.
All this goes back to the fundamental principle that sound is vibrations of air; different kinds of sounds are simply different kinds of vibrations.
Then the tube, like an ear trumpet, throws all the air vibrations in one direction, so that you hear the sound easily.
And the vibrations travel better in most other kinds of matter than they do in air.
And by tightening them, or making them smaller or shorter, the pitch can be made higher; that is, the number of vibrations to each second can be increased.
That is the way it would be if different kinds of air vibrations did not make different kinds of notes,--if there were no differences in pitch.
The pad is to keep the vibrations of the alarm from making the plate vibrate.
This starts the air vibrations which we call sound.
If you are far enough away from a flat wall or cliff, and shout, the sound (the air vibrations you start) is reflected back to you and you hear the echo.
In the same way, when the reproducing needle vibrates as it goes over the track made by the cutting needle, it would make air vibrations too slight for you to hear if it were not fastened to the diaphragm.
As we have already said, light is probablyvibrations or waves of ether.
Vibrations move rather slowly in air, compared with the speed at which they travel in other substances.
In the cochlea, the part of the inner ear concerned with hearing, the hairs are shaken by sound vibrations that have reached the liquid in which the whole end-organ is immersed.
Once started in this liquid, the vibrations are propagated through it to the sense cells of the cochlea and stimulate them in the way already suggested.
If you tune two whistles one vibration apart and sound them together, you get a tone that swells once a second; tune them ten vibrations apart and you get ten swellings or beats per second, and the effect is rough and disagreeable.
Go up an octave from this and you double the number of vibrations per second; go down an octave and you halve the number of vibrations.
The Sense of Hearing Sound, like light, is physically a wave motion, though the sound vibrations are very different from those of light.
Light and heat, then, are here vibrations of the atoms; and sound, on the other hand, is a vibration of the molecules composed of the atoms.
