Quotations list about frequency, amplitude and modulation captions citing Ernst Mayr, W. H. Auden and George Leonard sayings.
As a consequence, geneticists described evolution simply as a change in gene frequencies in populations, totally ignoring the fact that evolution consists of the two simultaneous but quite separate phenomena of adaptation and diversification.
— Ernst Mayr
Every European visitor to the United States is struck by the comparative rarity of what he would call a face, by the frequency of men and women who look like elderly babies. If he stays in the States for any length of time, he will learn that this cannot be put down to a lack of sensibility -- the American feels the joys and sufferings of human life as keenly as anybody else. The only plausible explanation I can find lies in his different attitude to the past. To have a face, in the European sense of the word, it would seem that one must not only enjoy and suffer but also desire to preserve the memory of even the most humiliating and unpleasant experiences of the past.
— W. H. Auden frequency quote
The simplest single-celled organism oscillates to a number of different frequencies, at the atomic, molecular, sub-cellular, and cellular levels. Microscopic movies of these organisms are striking for the ceaseless, rhythmic pulsation that is revealed. In an organism as complex as a human being, the frequencies of oscillation and the interactions between those frequencies are multitudinous.
— George Leonard
Though most of us don't hunt, our eyes are still the great monopolists of our senses. To taste or touch your enemy or your food, you have to be unnervingly close to it. To smell or hear it, you can risk being further off. But vision can rush through the fields and up the mountains, travel across time, country, and parsecs of outer space, and collect bushel baskets of information as it goes. Animals that hear high frequencies better than we do
— Diane Ackerman
For a smart material to be able to send out a more complex signal it needs to be nonlinear. If you hit a tuning fork twice as hard it will ring twice as loud but still at the same frequency. That's a linear response. If you hit a person twice as hard they're unlikely just to shout twice as loud. That property lets you learn more about the person than the tuning fork.
— frequency quotation by Neil Gershenfeld
[Ocean surf] has the frequency of roughly 12 cycles per minute.
And ... 12 cycles per minute is [also] roughly the frequency of the breathing of a sleeping human. There is a deep resonance with being at rest.
Philosophers and theologians have argued for centuries over the morality of targeted assassinations - a technique that the Israelis use with some frequency - without ever reaching anything approaching consensus.
I remember attaching a wire clothing hanger to the antenna of my radio in my bedroom, so I could get the frequency and get that station and listen to the top 10 every night.
I think people who vibrate at the same frequency, vibrate toward each other. They call it, in science, sympathetic vibrations.
God is a frequency. Stay tuned.
What Must I Do to Be Saved? It is impossible to ask a more weighty Question! It is deplorable that we hear it asked with no more Frequency, with nor more Agony.
It's very rare that publications double their frequency.
Our entire biological system, the brain and the earth itself, work on the same frequencies.
It's - as opposed to tape where you have a magnetic tape that's excited by frequencies that you hit, digital was a process where musical sounds are transferred to numbers and stored as numbers.
If you look at a record under a microscope, the high frequencies are short jagged edges... and the low frequencies are long swinging ones are deep bass sounds. When it cut it at half speed, you're getting more of those on the record.
I think one thing that helped the sound change, it's a real subtle thing;
it's just one switch on my bass, it has three positions, and I usually boost the mid-range frequency, I lowered the frequency that I boost, and that goes out to the sound system, too.
If you want to find the secrets of the universe, think in terms of energy, frequency and vibration.
While the Environmental Genome Project does not seek to assign allele frequencies, we are aware of the importance of accurate allele frequency estimates for future epidemiologic studies and the large sample sizes such estimates will require.
Yes, I get a report from BMI about the frequency of performances, and it is very surprising. They played one of my most advanced pieces, and one of my most unusual ones on the radio.
Machines take me by surprise with great frequency.
As seismologists gained more experience from earthquake records, it became obvious that the problem could not be reduced to a single peak acceleration. In fact, a full frequency of vibrations occurs.
For under certain conditions the chemical atoms emit light waves of a specific length or oscillation frequency - their familiar characteristic spectra - and these can come in the form of electromagnetic waves only from accelerated electric quanta.
This is funny because I just had a job over the summer for VH1, a project I did called Strange Frequency where I got to play a Goth rock band singer.
When the government picked companies and gave them monopoly rights to frequencies in San Francisco and Los Angeles and New York and Chicago, it was picking the winners of the competition; it wasn't setting the terms of the competition.
When the government allocates monopoly rights to frequency, and there are only a handful in each community, it's picking the winners in the competition.
I think people who vibrate at the same frequency, vibrate toward each other.
They call it, in science, sympathetic vibrations.
When a coil is operated with currents of very high frequency, beautiful brush effects may be produced, even if the coil be of comparatively small dimensions. The experimenter may vary them in many ways, and, if it were nothing else, they afford a pleasing sight.
I'm always open to the possibility that somebody's got a better idea than I have. It happens with some frequency.
What we call the 'world' and the 'universe' is only one frequency range in an infinite number sharing the same space. The interdimensional entities I write about are able to move between these frequencies or dimensions and manipulate our lives.
The fatigue produced on the muscles of the human frame does not altogether depend on the actual force employed in each effort, but partly on the frequency with which it is exerted.
Of course, relative citation frequencies are no measure of relative importance.
Who has not aspired to write a paper so fundamental that very soon it is known to everyone and cited by no one?
Ideas which have been developed simultaneously or in immediate succession in the same mind mutually reproduce each other, and do this with greater ease in the direction of the original succession and with a certainty proportional to the frequency with which they were together.
