Éter

the idea of the luminiferous aether was then abandoned.
a ideia do éter luminífero, foi então abandonada.

this contradicts the hypothesis of the complete aether drag.
this contradicts the hypothesis of the complete aether drag.

this contradicts the theory of the (nearly) stationary aether.
this contradicts the theory of the (nearly) stationary aether.

however, subsequent experimental efforts failed to detect the presence of the aether.
no entanto, os experimentos seguintes falharam em detectar a presença do éter.

at the same time, the modern theories of electromagnetic aether could not account for aberration at all.
ao mesmo tempo, as modernas teorias do éter eletromagnético não podiam contemplar a aberração.

the laws of propagation of waves in this type of aether are similar to the electromagnetic equations of maxwell."
as leis de propagação de ondas neste tipo de éter são semelhantes às equações eletromagnéticas de maxwell.”

aether also has the name "quintessence", meaning, literally, "fifth substance".
o éter também era conhecido pelo nome de "quintessência" — literalmente, "quinta substância".

george stokes proposed a similar theory, explaining that aberration occurs due to the flow of aether induced by the motion of the earth.
george stokes propôs uma teoria similar, explicando que a aberração ocorre devido ao fluxo de éter induzido pelo movimento da terra.

only a minority of theoretical physicists such as abraham, lorentz, poincaré, or langevin still believed in the existence of an aether.
only a few theoretical physicists like lorentz, poincaré, abraham or langevin, still believed in the existence of an aether in any form.

each story represents an element - earth, water, fire, wind and aether or void - in ascending order.
cada andar representa um elemento – terra, água, fogo, vento e éter ou vazio – em ordem crescente.

aristotle believed that all matter was made up of aether, or some combination of four elements: earth, water, air, and fire.
ele acreditava na existência de quatro elementos básicos, a terra, a água, o ar e o fogo.

michelson and morley devised an instrument capable of detecting the speed of the earth with respect to the aether at rest and, in this way, of obtaining a reference frame in absolute stillness.
michelson y morley idealizaram um instrumento que fosse capaz de detectar a velocidade da terra em relação ao etéreo repouso e, desta forma, obter um sistema de referência em quietude absoluta.

in his 1905 theory of special relativity, albert einstein reinterpreted the results of lorentz' theory in a much simpler and more natural conceptual framework which disposed of the idea of an aether.
na sua teoria de 1905 da relatividade restrita, albert einstein reinterpretou os resultados da teoria de lorentz em uma estrutura conceitual muito mais simples e natural, que dispensava a ideia de um éter.

in his lectures of around 1911 he pointed out that what "the theory of relativity has to say ... can be carried out independently of what one thinks of the aether and the time".
com isto o éter veio a contribuir com a ideia de que a luz seria uma onda, uma vez que precisaria de um meio material onde se propagar, e este meio foi chamado de éter.

based on the work of kepler and probably descartes, leibniz develops a model of planetary motion based on the "conatus" principle, the idea of aether and a fluid vortex.
baseado na obra de kepler e provavelmente de descartes, leibniz desenvolveu um modelo de movimento planetário a partir do princípio de "conatus", da ideia do éter e de um vórtice fluido.

however, maxwell's theory was unsatisfactory regarding the optics of moving bodies, and while he was able to present a complete mathematical model, he was not able to provide a coherent mechanical description of the aether.
entretanto, a teoria de maxwell era insatisfatória no que diz respeito à óptica e ao movimento dos corpos, e enquanto ele foi capaz de apresentar um modelo matemático completo, ele não pode prover uma descrição mecânica coerente do éter.

""in some other papers, poincaré (1895, 1900b) argued that experiments like that of michelson–morley show the impossibility of detecting the absolute motion of matter, i.e., the relative motion of matter in relation to the aether.
