Encyclopaedia Britannica, 11th Edition, Volume 8, Slice 4 "Diameter" to "Dinarchus" Fresnel and Amp�re for true ones, and then imagines my true results are like those erroneous ones. Experimental Researches in Electricity, Volume 1 It is true that his wave theory was far from the complete doctrine as subsequently developed by Thomas Young and Augustin Fresnel, and belonged rather to geometrical than to physical Optics. Treatise on Light If it be admitted that a photographic impression results from the active force of the vibratory movement of the ether, the question is, in fact, completely elucidated, and the discrepancy is abolished in Fresnel's favour. The New Physics and Its Evolution He is said also to have made a lens from a solid piece of glass by grinding it in concentric steps similar to the designs worked out by Fresnel seventy years later.

Six Lectures on Light Delivered In The United States In 1872-1873 It was, in consequence, necessarily transverse, and thus coincided with the vibration of Fresnel; while the corresponding magnetic vibration was perpendicular to it, and would coincide with the luminous vibration of Neumann. The New Physics and Its Evolution The only ruins mentioned by Haines are extensive ones near Haffer, towards the western part of the plain; and this Fresnel considers to be the site of the former city.

The Vital Message I should like to read to you a brief extract from a letter written by Fresnel to Young in 1824, as it throws a pleasant light upon the character of the French philosopher. Six Lectures on Light Delivered In The United States In 1872-1873 Fresnel perceived that this experiment absolutely compels us to reject the hypothesis of longitudinal vibrations acting along the line of propagation in the direction of the rays. The New Physics and Its Evolution K - v/K, which is in accordance with Fresnel's law. The Project Gutenberg Encyclopedia Volume 1 of 28 Fresnel commenced his researches with an examination of the fringes, external and internal, which accompany the shadow of a narrow opaque strip, such as a wire. Encyclopaedia Britannica, 11th Edition, Volume 8, Slice 4 "Diameter" to "Dinarchus" And still another is the well-known instance of the change in polarization predicted by Fresnel from the mere interpretation of an algebraic symbol. The Atlantic Monthly, Volume 05, No. 30, April, 1860 After him came Fresnel, whose transcendent mathematical abilities enabled him to give the theory a generality unattained by Young. Six Lectures on Light Delivered In The United States In 1872-1873 After having been eclipsed for two hundred years by the success of the immortal synthesis of Newton, it gained an entirely new splendour with Fresnel and his followers. The New Physics and Its Evolution Young’s theory was reproduced in France by Fresnel. Unconscious Memory The command of the enemy army then devolved onto the Austrian General Fresnel who ordered a retreat, and the French army continued on its way peacefully towards the Rhine. The Memoirs of General Baron De Marbot Five minutes later Fresnel was securely bound to a chair, and effectively silenced by a very uncomfortable gag improvised out of a block of wood and a muffler. Scaramouche But the question early arose in the mind of Fresnel whether the ether is not considerably affected by contact with the particles of solids. A History of Science — Volume 3 It is not the optics of Fresnel which absorbs the science of electricity, it is rather the optics which is swallowed up by a more general theory. The New Physics and Its Evolution The lantern held a revolving light, with a four-wick Fresnel lamp, burning sperm oil. The Ruling Passion; tales of nature and human nature He rather supposes, in opposition to Fresnel's idea, that the density of the ether remains the same in all media, while its coefficient of elasticity is variable. The New Physics and Its Evolution Meanwhile he chuckled at the thought of Fresnel as he had last seen him, with his muffled face and glaring eyeballs. Scaramouche A few months later Fresnel was dead, and Young survived him only two years. A History of Science — Volume 3 The Luminiferous Ether: First idea of Ether due to Descartes—Ether must be imponderable—Fresnel shows light vibrations to be transverse—Transverse vibrations cannot exist in fluid—Ether must be discontinuous. The New Physics and Its Evolution Arago at once recognized the merit of Fresnel's work, and soon became a convert to the theory. A History of Science — Volume 3 After Fresnel's admission to the Institute in 1823 the opposition weakened, and gradually the philosophers came to realize the merits of a theory which Young had vainly called to their attention a full quarter-century before. A History of Science — Volume 3 Fresnel dipped a hand into his pocket, and fetched thence a key. Scaramouche The most recent speculations regarding the properties of the ether have departed but little from the early ideas of Young and Fresnel. A History of Science — Volume 3 Radiations: Wave-lengths and their measurements—Rubens' and Lenard's researches— Stationary waves and colour-photography—Fresnel's hypothesis opposed by Neumann—Wiener's and Cotton's experiments. The New Physics and Its Evolution Now, thanks largely to Arago, both Young and Fresnel received their full meed of appreciation. A History of Science — Volume 3 He told Fresnel that Young had anticipated him as regards the general theory, but that much remained to be done, and he offered to associate himself with Fresnel in prosecuting the investigation. A History of Science — Volume 3 Fresnel," he said, quietly, "if, as you say, the gallows claim me, the thing that has brought me to this extremity arises out of the shooting of Mabey. Scaramouche The doctrine of Young and Fresnel was as a highway leading surely on to the wide plain of conservation. A History of Science — Volume 3 Fresnel founded his theory of double refraction and reflexion by transparent surfaces, on the hypothesis that the vibration of a ray of polarized light is perpendicular to the plane of polarization.
