    • A volatile, extremely flammable fluid, C2H5OC2H5, derived from the distillation of ethyl alcoholic beverages with sulfuric acid and utilized as a reagent and solvent. It absolutely was formerly made use of as an anesthetic. Also referred to as diethyl ether, ethyl ether.
    • The areas of area beyond our planet's atmosphere; the heavens.
    • The element thought in ancient and medieval civilizations to fill all area above the world associated with the moon and also to create the performers and planets.
    • Physics An all-pervading, infinitely elastic, massless method formerly postulated as the method of propagation of electromagnetic waves.

    • A medium of good elasticity and severe tenuity, once expected to pervade all area, the inner of solid bodies perhaps not excepted, and end up being the method of transmission of light as well as heat; hence known as luminiferous ether. Its no longer thought that such a medium is required for the transmission of electromagnetic waves; the current utilization of the term is mainly a figurative term for vacant space, and for literary effect, and not designed to suggest the actual existence of a physical medium. However. modern cosmological concepts considering quantum field concept try not to exclude the chance that the inherent energy of machine is greater than zero, in which particular case the concept of an ether pervading the machine may have over metaphoric definition.

    • In astronomy and physics, a hypothetical method of extreme tenuity and elasticity allowed to be diffused throughout all space (and on the list of molecules of which solid bodies are comprised), and be the method associated with the transmission of light and heat. Understand herb.
    • In chem.: One of a class of organic figures divided in to two groups: Simple ethers, composed of two fundamental hydrocarbon radicals united by oxygen, and corresponding in constitution toward metallic oxids, as CH3OCH3, methylether, or methyloxid, analogous to AgOAg, silver oxid. Substance ethers, consisting of one or more basic or alcoholic beverages radicals plus one or higher acid hydrocarbon radicals united by oxygen, and matching to salts of the metals, as CH3COO C2H5, ethyl acetate, or acetic ether, corresponding to CH3COONa, salt acetate.
