carrier wave

From carrier + wave. Sense 2 (“soliton”) was coined by the Scottish civil engineer, naval architect, and shipbuilder John Scott Russell (1808–1882): see the quotations.

This invention relates to carrier wave signaling systems and more particularly to systems of multiplex telephony employing carrier waves wherein such carrier waves of distinctive frequencies are normally impressed upon the transmission medium. Such medium may comprise any of the natural media employed in radio transmission or a conductive transmission line of any kind.

1920 December 21, Charles White, Carrier-wave Signaling System, US Patent 1,480,235 (PDF version), page 1, column 1:

I have a waterproof basket arranged on my operating table, and when the static waves come over it, they fall in. There is no trouble in receiving music, however, for the audio frequency voice waves are superimposed on a carrier wave. This carrier wave carries the music over the basket, without falling, into the set.

1922 August, Monroe Worthington, “A Hill Billy’s Radio”, in Hugo Gernsback, editor, Radio News, volume 4, number 2, New York, N.Y.: Experimenter Publishing, →OCLC, page 300:

Means for continuously obtaining information sufficient to determine the instantaneous position of an airplane with respect to three ground points located at the vertices of a triangle, said means comprising a control station located at the first of said ground points, said control station comprising a local oscillator and means for radiating a first carrier wave modulated by the frequency of said local oscillator, [...]

1944 May 4, Paul W. Nosker, System for Determining the Position or Path of an Object in Space, US Patent 2,470,787 (PDF version), column 10:

[T]he "wireless" already depended on a wave system as the medium; how could another wave system (the signal) be carried by the wave system of the medium? Reginald Fessenden, a Canadian, was one of the first to solve this problem. His idea was to superimpose the signal wave on the carrier wave: to "modulate" the carrier wave. This is the basic concept of radio and television. Since there are two variables associated with a wave—"amplitude" or strength, and "frequency" or "wavelength"—there were two possibilities for modulation: hence the current AM (Amplitude Modulation) and FM (Frequency Modulation) systems of broadcasting.

1977, James Monaco, “Media”, in How to Read a Film: The Art, Technology, Language, History, and Theory of Film and Media, New York, N.Y.: Oxford University Press, →OCLC, pages 349–350:

(physics) A wave that can be modulated, either in amplitude, frequency, or phase, to carry or transmit images, music, speech, or other signals.

wave that can be modulated to transmit signals

The same propagation through the same ether brought the rays of the sun's light from the sun to the earth, and the same carrier wave brought from the other side of the globe, from the oceans there, which were disturbed by the attraction of the sun and moon, those waves all round the coasts which were called tides. All these phenomena, from the tides and the wind to the rays of light and to the sounds of the telephone, were the motion of one simple phenomenon, the carrier wave, the wave of translation.

1877 November 30, J[ohn] Scott Russell, “[The Telephone. By Professor A[lexander] Graham Bell.] Discussion.”, in Journal of the Society of Arts, volume XXVI, number 1,306, London: Published for the Society [Royal Society of Arts] by George Bell and Sons, […], published 1878, →OCLC, page 23, column 2:

Noise is caused by a shock or stroke or beat given to some mass of matter. The shock tells on the mass of air near the struck body. It sends this mass of air into a heap near the struck body. This heap forms an air wave. [...] This wave is the carrier of the shock through great distances in the air, it travels with great speed. This "carrier wave" takes the shock of the stroke from afar, to the ear of the listener.

1878, J[ohn] Scott Russell, “Symmetry, Harmony, and Melody”, in Geometry in Modern Life, Being the Substance of Two Lectures on Useful Geometry, Given before the Literary Society at Eton, Eton, Berkshire: Williams and Son; London: Simpkin, Marshall, and Co., →OCLC, page 137:

Mr. [John Scott] Russell not only observed the shape and characteristics of the wave, which he called the carrier wave, or wave of translation, but he noticed the form which water assumed in filling up a cavity; and one of the means he used for this purpose was to have a boat towed at moderate and also at high velocities, and to observe the waves which followed her. These waves he found to be different from carrier waves, and he calls them following waves, or waves of replacement.

1878 March 23, J. Hyslop, “Yachting. The Wave-line Theory. Its Practical Application.”, in The Country: A Weekly Journal Devoted to the Dog, the Gun, Yachting, Fishing and All Out-door Sports, volume I, number 22, New York, N.Y.: “The Country” Publishing Association, →OCLC, no. II, page 312, column 1:

[M]eans must be taken first to create a series of solitary waves, and then to make these waves act as carrier waves, transporting the sounds from the instrument to the ear at a distance. In other words, the operation carried on in the instrument differs from the operation carried on through the air and from the effect delivered by the carrier wave.

Blahin (editors), Transactions of the Moscow Mathematical Society for the Year 1972, Volume 27, [ТРУДЫ МОСКОВКОГО МАТЕМАҬИЧЕСКОГО ОБЩЕСТВА ТОМ 27 (1972)], American Mathematical Society, page 202,
The first notion of a Laplace operator for functionals on a Hilbert space was introduced by Levy in [l], and the idea was developed further in [2]. Levy's results depended on the posthumous work of Gateaux [3] in which the Dirichlet problem in Hilbert space was considered (without any concise definition of the Laplace operator).

Nevertheless, a systematic analysis of heat semigroups for Laplace operators on metric graphs is still missing.[…]Below we will prove an upper bound on the number of negative eigenvalues (Theorem 3.7) and a lower bound on the spectrum of Laplace operators (Theorem 3.10).

einstein

From German ein Stein, "one stone", coined by scientists in recent decades, but with tongue-in-cheek tacit acknowledgment of the homonymy with einstein and Einstein; "a pun playing with the famous scientist's name and the German term "ein Stein" for "one stone".

In less poetic terms, an einstein is an “aperiodic monotile,” a shape that tiles a plane, or an infinite two-dimensional flat surface, but only in a nonrepeating pattern. (The term “einstein” comes from the German “ein stein,” or “one stone” — more loosely, “one tile” or “one shape.”)

coin

But most theories predict that equal amounts of matter and antimatter should have been produced during the big bang, and the mystery of what happened to all the antimatter is a central question in fundamental physics.

2023 September 27, Hannah Devlin, “Scientists find antimatter is subject to gravity”, in The Guardian, →ISSN:

(physics) Matter that is composed of the antiparticles of those that constitute normal matter.

Particles of matter and antimatter are identical, except for an opposite electrical charge. An electron has a negative charge whereas its antiparticle, the positron, has a positive charge, and both have an identical mass.

2010 November 19, Alok Jha, “We can't see antimatter but it really does matter”, in The Guardian, →ISSN:

(physics) A form of matter that has a key property, such as charge, opposite to that of ordinary matter.
