Bojoval proti nejvìtím uznávaným osobnostem té doby, pøitom pracoval mimo hlavní centra vìdy. Nemì pøístup k leterárním pramenùm, nemìl ani pomùcky. Pøesto závìry jeho práce zùstaly platné dodnes. pouze se mýlil v pøedstavì o elastickém éteru. Tomuto fyzikovi vdìèíme nejen za mnoho pozorování pøi ohybu a interferenci svìtla, ale hlavnì za teorii ohybu ve formì zónové konstrukce, která vtìlila Huyghensùv princip vlnoploch do mylenky interference.

Finistère Augustin Fresnel S'il n'y avait qu'un nom propre associé à l'histoire des phares de France, ce serait sans doute celui de Fresnel. Augustin Fresnel, savant et ingénieur des Ponts-et-Chaussées, né en 1788 mort en 1827, à l'âge de 39 ans. Il est l'inventeur des appareils lenticulaires qui, au début du XIXe siècle, révolutionnèrent les techniques employées pour l'éclairage des feux. L'origine des phares modernes s'est en effet condensée sur les objets dont on lui attribue la paternité, des lentilles de verre conservées comme de pieuses reliques par plusieurs institutions scientifiques.

Other descriptions of Fresnel lens Lens of a lighthouse in Rozewie A Fresnel lens is a type of lens invented by Augustin-Jean Fresnel . Originally developed for lighthouses , the design enables the construction of lenses of large size and short focal length without the weight and volume of material which would be required in a lens of conventional design.

Extractions: French physicist who independently conducted some of the same experiments as Young . Fresnel showed that only a transverse wave theory of light could account for double refraction To derive the Fresnel equations of reflection and refraction he worked backwards from the known properties of light to derive a dynamical theory. Fresnel also developed the mathematical theory of refraction and polarization in anisotropic crystals. From this theory, William Rowan Hamilton predicted conical refraction which was subsequently discovered. In his model, light consisted of two components with electric fields at right angle to each other. In 1819, during the judging of Fresnel's paper on diffraction at the Paris Academy, Poisson argued that the consequence of Fresnel's theory was that the center of the shadow of a diffracting disk should be illuminated. This unexpected effect was subsequent observed, verifying Fresnel's theory. Fresnel also suggested that permanent magnets could be described by aligned currents circulating around molecules. Fresnel rejected the corpuscular theory of light in favor of a dynamical theory of "luminiferous

Extractions: Version for printing Augustin Fresnel We should note that Jacques and Augustine Fresnel were Jansenists; that is they were followers of Cornelius Otto Jansen (1585-1638) who led the Roman Catholic reform movement named after him. Jansen argued that men cannot achieve salvation through their actions since it is predestined who Christ will lead to eternal life, the select few, and who are doomed to damnation, the multitude. Augustin was brought up with strict Jansenist values in a stern atmosphere which would strongly influence him for the rest of his life. The French Revolution began with the storming of the Bastille on 14 July 1789 when Augustin was one year old. Louis XVI was executed on 21 January 1793 and there followed the reign of terror. In 1794, when Augustin was now six years old, the political situation in France was so difficult that the construction work on the harbour at Cherbourg had to be halted. The Fresnel family went to Mathieu, a village north of Caen. There young Fresnel spent the rest of his childhood years, and there his elementary education was provided by his parents. There is no record of any educational achievements by the young boy at this stage and, although it may be a little harsh on his parents to say so, it appears that they completely failed to bring out their son's talents.

Extractions: Or search the encyclopaedia: Fresnel, Augustin Jean French physicist who refined the theory of polarized light . Fresnel realized in 1821 that light waves do not vibrate like sound waves longitudinally, in the direction of their motion, but transversely, at right angles to the direction of the propagated wave. Fresnel first had to confirm the wave theory of light. He demonstrated mathematically that the dimensions of light and dark bands produced by diffraction could be related to the wavelength of the light producing them if light consisted of waves. To explain double refraction, he then arrived at the theory of transverse waves.
