Henri Becquerel : une étonnante expérience. He undertook to investigate whether there was some fundamental connection between this invisible radiation and visible light such that all luminescent materials, however stimulated, would also yield X rays. Le grand-père d'Henri Becquerel, Antoine César (Châtillon-Coligny, Loiret, 1788-Paris 1878), après avoir participé aux campagnes d'Espagne comme officier du génie, est attiré par l'étude des phénomènes électriques. On 2 March 1896 he reported: I will insist particularly upon the following fact, which seems to me quite important and beyond the phenomena which one could expect to observe: The same crystalline crusts [of potassium uranyl sulfate], arranged the same way with respect to the photographic plates, in the same conditions and through the same screens, but sheltered from the excitation of incident rays and kept in darkness, still produce the same photographic images.

Antoine-Henri Becquerel (Paris, 15 de dezembro de 1852 — Le Croisic, 25 de agosto de 1908) foi um físico francês. He was awarded the Nobel Prize for Physics in 1903, which he shared with physicists Pierre and Marie Curie. Il a remporté le prix Nobel de physique en 1903 avec Pierre et Marie Curie pour cette découverte. He thus confirmed his view that something very similar to X rays was emitted by this luminescent substance at the same time it threw off visible radiation. Antoine Henri Becquerel (15 December 1852 – 25 August 1908) was a French physicist, Nobel laureate, and the discoverer of radioactivity along with Marie Skłodowska-Curie and Pierre Curie, for which all three won the 1903 Nobel Prize in Physics. Author of. own great talent. 1870 [5] Becquerel's other experiments allowed him to research more into radioactivity and figure out different aspects of the magnetic field when radiation is introduced into the magnetic field. [6] In 1890 he married Louise Désirée Lorieux. [22] In 1903, Henri shared a Nobel Prize in Physics with Pierre Curie and Marie Curie for the discovery of spontaneous radioactivity. His family had produced four generations of scientists. Henri then concerned himself with infrared radiation, examining, among other things, the spectra of different phosphorescent crystals under infrared stimulation. Henri Becquerel was a French physicist who investigated uranium and other substances which led to his discovery of radioactivity. Becquerel was born in Paris, France on December 15, 1852. La radioactivité n’est pas une invention humaine. "When different radioactive substances were put in the magnetic field, they deflected in different directions or not at all, showing that there were three classes of radioactivity: negative, positive, and electrically neutral. Définition et Explications - Antoine Henri Becquerel (15 décembre 1852, Paris - 25 août 1908, Le Croisic, France) est un physicien français. Henri Becquerel était un physicien français qui a découvert la radioactivité. Becquerel foi o responsável pelos estudos que levaram à descoberta do fenômeno da radioatividade. [5][7] In 1901 Becquerel made the discovery that radioactivity could be used for medicine. Son grand-père, Antoine Becquerel, est considéré comme le découvreur, en 1839, de l'effet photovoltaïque dont le principe est utilisé dans les capteurs solaires qui devraient produire une part de plus en plus importante de l'énergie électrique "renouvelable" de notre futur. en 1892, après la mort de son père.

Både far og farfar hans var fysikarar som underviste ved det naturhistoriske museet i Paris. The SI unit for radioactivity, the becquerel (Bq), is named after him. Son grand-père, Antoine Becquerel, est considéré comme le découvreur, en 1839, de l'effet photovoltaïque dont le principe est utilisé dans les capteurs solaires qui devraient produire une part de plus en plus importante de l'énergie électrique "renouvelable" de notre futur. Histoire/Géographie/Education civique : en route pour le DNB - Janvier 2014. Becquerel, who invented a new method for spectroscopic analysis. During 1896 Becquerel published seven papers on radioactivity, as Marie Curie later named the phenomenon; in 1897, only two papers; and in 1898, none. I hope that the experiments which I am pursuing at the moment will be able to bring some clarification to this new class of phenomena. He belonged to a family of distinguished scholars and scientists. By May 1896, after other experiments involving non-phosphorescent uranium salts, he arrived at the correct explanation, namely that the penetrating radiation came from the uranium itself, without any need for excitation by an external energy source. Antoine Henri Becquerel (født 15. december 1852 i Paris, død 25. august 1908 i Le Croisic) var en fransk fysiker, der i 1903 delte Nobelprisen i fysik med Pierre og Marie Curie for sit studie om radioaktivitet.. SI-enheden for måling af radioaktivitet er opkaldt efter ham.. Referencer [12][13] By 1861, Niepce de Saint-Victor realized that uranium salts produce "a radiation that is invisible to our eyes". La découverte de la radioactivité naturelle par trois savants français à la fin du XIXème siècle – Henri Becquerel puis Pierre et Marie Curie – a posé toute une série d'énigmes, concernant la nature et l'origine de ces rayonnements invisibles, et de l'énergie qu'ils véhiculaient. Tout au long du XXe siècle, des physiciens devenus célèbres ont appris à apprivoiser ses 1903 Nobel Fizik Ödülü sahibi. Electricity, magnetism, optical phenomena, and energy were major areas of physical investigation during the 19th century. Entré à l'Ecole Polytechnique en 1872, il en sort en 1874 dans le corps des Ponts et Chaussées. Get exclusive access to content from our 1768 First Edition with your subscription.

Antoine-Henri Becquerel a étudié à l'École polytechnique. Henri Becquerel, 15.12.1852-25.8.1908, fransk fysiker, som opdagede radioaktiviteten. Henri made this discovery when he left a piece of radium in his vest pocket and noticed that he had been burnt by it. For work in this field he, along with Marie Skłodowska-Curie (Marie Curie) and Pierre Curie,[3] received the 1903 Nobel Prize in Physics. Nach einer normalen schulischen Ausbildung und dem Studium an der berühmten École Polytechnique von 1872 bis 1874 setzte BECQUEREL sein Studium von 1874 bis 1877 an einer Ingenieursschule fort und wurde zum … Our editors will review what you’ve submitted and determine whether to revise the article. Later on in 1894, Becquerel became chief engineer in the Department of Bridges and Highways before he started with his early experiments. Antoine Henri Becquerel Antoine Henri Becquerel (* 15. From the charge to mass value thus obtained, he showed that the beta particle was the same as Joseph John Thomson’s recently identified electron. This discovery led to the development of radiotherapy which is now used to treat cancer. Since the sun did not come out in the following days, I developed the photographic plates on the 1st of March, expecting to find the images very weak. Antoine Henri Becquerel (born December 15, 1852 in Paris, France), known as Henri Becquerel, was a French physicist who discovered radioactivity, a process in which an atomic nucleus emits particles because it is unstable. [8] His death was caused by unknown causes, but was reported that "he had developed serious burns on his skin, likely from the handling of radioactive materials. During the experiment, Röntgen "found that the Crookes tubes he had been using to study cathode rays emitted a new kind of invisible ray that was capable of penetrating through black paper". "[11], As often happens in science, radioactivity came close to being discovered nearly four decades earlier in 1857, when Abel Niépce de Saint-Victor, who was investigating photography under Michel Eugène Chevreul, observed that uranium salts emitted radiation that could darken photographic emulsions. Here is how I was led to make this observation: among the preceding experiments, some had been prepared on Wednesday the 26th and Thursday the 27th of February, and since the sun was out only intermittently on these days, I kept the apparatuses prepared and returned the cases to the darkness of a bureau drawer, leaving in place the crusts of the uranium salt. Antoine Henri Becquerel (ejtsd: antoán anri bekerel) (Párizs, Franciaország, 1852. december 15. [23] In 1906, Henri was elected Vice Chairman of the academy, and in 1908, the year of his death, Becquerel was elected Permanent Secretary of the Académie des Sciences. But further experiments led him to doubt and then abandon this hypothesis. Niepce de Saint-Victor knew Edmond Becquerel, Henri Becquerel's father. Professor of the History of Science, University of California, Santa Barbara. En 1875, il entra dans le département des ponts et routes, et devint ingénieur en chef en 1894. Antoine Henri Becquerel (15 Aralık 1852 – 25 Ağustos 1908), Fransız fizikçi, radyoaktivitenin kaşiflerinden. [26][27] The uranium-based mineral becquerelite was named after Henri. Becquerel was born in Paris into a wealthy family which produced four generations of physicists: Becquerel's grandfather (Antoine César Becquerel), father (Alexandre-Edmond Becquerel), and son (Jean Becquerel). In 1903 he shared the Nobel Prize for Physics with Pierre and Marie Curie. The SI unit for radioactivity, the becquerel (Bq), is named after him. Describing them to the French Academy of Sciences on 27 February 1896, he said: One wraps a Lumière photographic plate with a bromide emulsion in two sheets of very thick black paper, such that the plate does not become clouded upon being exposed to the sun for a day. [10] There followed a period of intense research into radioactivity, including the determination that the element thorium is also radioactive and the discovery of additional radioactive elements polonium and radium by Marie Skłodowska-Curie and her husband Pierre Curie. In 1896, French scientist Antoine Henri Becquerel discovered radioactivity which was an early contribution to atomic theory. He was a member of a scientific family extending through several generations, the most notable being his grandfather Antoine-César Becquerel (1788–1878), his father, Alexandre-Edmond Becquerel (1820–91), and his son Jean Becquerel (1878–1953). [5] In 1900, Becquerel won the Rumford Medal for his discovery of the radioactivity of uranium and he was made an Officer of the Legion of Honour. He was born in Paris into a family of great scientists.

For several years the young man’s research was concerned with the rotation of plane-polarized light by magnetic fields, a subject opened by Michael Faraday and to which Henri’s father had also contributed. En décembre 1895, le physicien allemand Wilhelm Röntgen découvre les rayons X, utilisés aujourd’hui dans de nombreuses applications comme l’imagerie médicale. Antoine Henri Becquerel (1852-1908), son of the lastnamed, who succeeded to his chair at the Musee d'Histoire Naturelle in 1892, was born in Paris on the 15th of December 1852, studied at the Ecole Polytechnique, where he was appointed a professor in 1895, and in 1875 entered the department des post Henri BECQUEREL, fils d'Edmond naît à paris en 1852 dans ce Muséum où son père est né, habite et travaille. Damit wuchs auch HENRI BECQUEREL in einer Umgebung auf, in der er schon früh mit naturwissenschaftlichen und speziell mit physikalischen Problemen bekannt wurde. Henri worked alongside Marie Curie and Pierre Curie. [24] During his lifetime, Becquerel was honored with membership into the Accademia dei Lincei and the Royal Academy of Berlin. It required the extension in 1898 of radioactivity to another known element, thorium (by Gerhard Carl Schmidt and independently by Marie Curie), and the discovery of new radioactive materials, polonium and radium (by Pierre and Marie Curie and their colleague, Gustave Bémont), to awaken the world and Becquerel to the significance of his discovery. Fils et petit-fils de physiciens et d'Académiciens des sciences, Becquerel est un enfant du sérail. Others may have noticed this before him, but his report in 1901 of the burn caused when he carried an active sample of the Curies’ radium in his vest pocket inspired investigation by physicians, leading ultimately to medical use.
