In the 19th century, luminiferous aether (or ether), meaning light-bearing aether, was a theorized medium for the propagation of light. James Clerk Maxwell developed a model to explain electric and magnetic phenomena using the aether, a model that led to what are now called Maxwell's equations and the understanding that light is an ...
According to ancient and medieval science, aether (/ ˈ iː θ ər /, alternative spellings include æther, aither, and ether), also known as the fifth element or quintessence, is the material that fills the region of the universe beyond the terrestrial sphere. [1]
Luminiferous aether or ether [1] (luminiferous meaning 'light-bearing') was the postulated medium for the propagation of light. [2] It was invoked to explain the ability of the apparently wave-based light to propagate through empty space (a vacuum), something that waves should not be able to do. The assumption of a spatial plenum (space ...
Ether, a class of chemical compounds Diethyl ether, or simply ether, an organic compound; Petroleum ether, a petroleum fraction (not classified as an ether) AETHER, an atmospheric radiative transfer algorithm; Efir, now called "Sfera," is a telecommunication project of the Russian Federation aiming to create a national Satellite constellation
The Experiments on the relative motion of the earth and ether have been completed and the result decidedly negative. The expected deviation of the interference fringes from the zero should have been 0.40 of a fringe – the maximum displacement was 0.02 and the average much less than 0.01 – and then not in the right place.
A cyclic ether and high-boiling solvent (b.p. 101.1 °C). Tetrahydrofuran (THF) A cyclic ether, one of the most polar simple ethers that is used as a solvent. Anisole (methoxybenzene) An aryl ether and a major constituent of the essential oil of anise seed. Crown ethers: Cyclic polyethers that are used as phase transfer catalysts. Polyethylene ...
The price of ether jumped as much as 18% Monday and was up another 8.6% at $3,802 late Tuesday morning before retreating slightly to hover at around $3,747 Tuesday afternoon.
"The Immortal Self (Ātman) is the sun shining in the sky, he is the breeze blowing in space, he is the fire burning on the altar, he is the guest dwelling in the house; he is in all men, he is in the gods, he is in the ether, he is wherever there is truth; he is the fish that is born in waters, he is the plant that grows in the soil, he is the ...
