Wiktionary

  1. ether(Noun)

    A compound containing an oxygen atom bonded to two hydrocarbon groups.

  2. ether(Noun)

    Diethyl ether (CHO), a compound used as an early anaesthetic.

  3. ether(Noun)

    A classical physical element, considered as prevalent in the heavens and inaccessible to humans. In some versions of alchemy, this was the fifth element in addition to air, earth, fire and water.

  4. ether(Noun)

    A substance (aether) once thought to fill all space that allowed electromagnetic waves to pass through it and interact with matter, without exerting any resistance to matter or energy (disproved by Einstein in his Theory of Relativity).

  5. ether(Noun)

  6. Ether(ProperNoun)

Webster Dictionary

  1. Ether(noun)

    a medium of great elasticity and extreme tenuity, supposed to pervade all space, the interior of solid bodies not excepted, and to be the medium of transmission of light and heat; hence often called luminiferous ether

  2. Ether(noun)

    supposed matter above the air; the air itself

  3. Ether(noun)

    a light, volatile, mobile, inflammable liquid, (C2H5)2O, of a characteristic aromatic odor, obtained by the distillation of alcohol with sulphuric acid, and hence called also sulphuric ether. It is powerful solvent of fats, resins, and pyroxylin, but finds its chief use as an anaesthetic. Called also ethyl oxide

  4. Ether(noun)

    any similar oxide of hydrocarbon radicals; as, amyl ether; valeric ether

Freebase

  1. Ether

    Ethers are a class of organic compounds that contain an ether group — an oxygen atom connected to two alkyl or aryl groups — of general formula R–O–R'. A typical example is the solvent and anesthetic diethyl ether, commonly referred to simply as "ether". Ethers are common in organic chemistry and pervasive in biochemistry, as they are common linkages in carbohydrates and lignin.

The Nuttall Encyclopedia

  1. Ether

    a volatic liquid prepared from the distillation of alcohol and sulphuric acid at high temperature; is colourless, and emits a sweet, penetrating odour; is highly combustible; a useful solvent, and an important anæsthetic.

  2. Ether

    a subtle element presumed to pervade all interstellar space, vibrations in which are assumed to account for the transmission of light and all radiant energy.

The Standard Electrical Dictionary

  1. Ether

    The ether is a hypothetical thing that was invented to explain the phenomena of light. Light is theoretically due to transverse vibrations of the ether. Since the days of Young the conception of the ether has extended, and now light, "radiant heat," and electricity are all treated as phenomena of the ether. Electrical attraction and repulsion are explained by considering them due to local stresses in the ether; magnetic phenomena as due to local whirlpools therein. The ether was originally called the luminiferous ether, but the adjective should now be dropped. Its density is put at 936E-21 that of water, or equal to that of the atmosphere at 210 miles above the earth's surface. Its rigidity is about 1E-9 that of steel (see Ten, Powers of); as a whole it is comparable to an all-pervading jelly, with almost perfect elasticity. The most complete vacuum is filled with ether. All this is a hypothesis, for the ether has never been proved to exist. Whether gravitation will ever be explained by It remains to be seen. [Transcriber's note: The Michelson-Morley experiment in 1887 (five years before this book) cast serious doubt on the ether. In 1905 Einstein explained electromagnetic phenomenon with photons. In 1963 Edward M. Purcell used special relativity to derive the existence of magnetism and radiation.]

The Foolish Dictionary, by Gideon Wurdz

  1. ETHER

    One of the world's three great composers--the others being Gas and Chloroform--whose airs are popular among the suffering.
