Andre-Marie Ampere by Bonni Raine Andre-Marie Ampere was a French physicist who founded and named the science of electrodynamics, now known as electromagnetism. He was born January 22, 1775 and was a child prodigy who educated himself through dilligant reading in the family's library. He survived the French revolution and began his work as a science teacher. This scientist is considered as one of the founders of the theory of electricity. The ampere, the unit of electric current, is named after him. Ampere was a prodigy who mastered all mathematics then extant by the time he was 12 years old. He became a professor of physics and chemistry at Bourg in 1801 and a professor of mathematics at the Ecole Polytechnique in Paris in 1809.

Andre-Marie Ampere Michael Faraday Friedrich Koepe Georg Ohm ... James Watt Andre-Marie Ampere Born: 20 Jan 1775 in Lyon, France Died: 10 June 1836 in Marseilles, France Despite not attending school, AndrŽ-Marie Ampere was to be given an excellent education. t has been claimed that Ampre had mastered all known mathematics by the age of twelve years but this seems somewhat of an exaggeration since, by Ampre's own account, he did not start to read elementary mathematics books until he was 13 years old. In 1797 Ampere earned a living tutoring mathematics until 1802 when he was appointed professor of physics and chemistry at Bourg Ecole Centrale. Appointed professor of mathematics at the Ecole Polytechnique in 1809 he held posts there until 1828. Ampere was appointed to a chair at Universite de France in 1826 which he held until his death. Although a mathematics professor, his interests included, in addition to mathematics, metaphysics, physics and chemistry. Ampere was also making significant contributions to chemistry. Ampre also worked on the theory of light, publishing on refraction of light in 1815. By 1816 he was a strong advocate of a wave theory of light, agreeing with Fresnel and opposed to Biot and Laplace who advocated a corpuscular theory. In the early 1820's, Ampere attempted to give a combined theory of electricity and magnetism after hearing about experimental results by Danish physicist Hans Christian Orsted. Ampere formulated a circuit force law and treated magnetism by postulating small closed circuits inside the magnetised substance.

André-Marie Ampère (Polémieux, Lyon, 1775 - Marselha, 1836) Físico francês. De formação autodidacta, manifesta interesse por todos os ramos do conhecimento. A partir de 1801 divide-se por estudos de Física e Química. Um ano mais tarde escreve o seu primeiro estudo científico, que versa sobre a teoria do jogo. A partir de 1805 ensina na Escola Politécnica de Paris. Napoleão, em reconhecimento do seu talento, nomeia-o inspector-geral de instrução pública em 1808. Em 1814 ingressa na Academia de Ciências e, em 1824, no Colégio de França. Entre 1807 e 1815 dedica-se a investigações químicas; estabelece a diferença entre átomos e moléculas e enuncia o chamado «princípio de Avogadro» independentemente do investigador italiano assim chamado. Formula as leis básicas do electromagnetismo, que expõe no seu estudo Sobre a teoria matemática dos fenómenos electrodinâmicos deduzida unicamente através da experiência (1827). A sua vida privada é uma sequência de infortúnios: em 1793 o seu pai, um rico comerciante, morre na guilhotina; em 1803 morre a sua mulher, após um brevíssimo matrimónio; volta a casar-se, mas este segundo casamento redunda em infelicidade. Ao longo da sua vida experimenta períodos de desânimo seguidos de momentos de entusiasmo. O campo de investigação que melhor cultiva é o dos fenómenos eléctricos. Em 1820, interessado pelas experiências de Oersted sobre o desvio das agulhas magnetizadas por uma corrente eléctrica, começa a estudar os fenómenos electromagnéticos. No decurso das suas investigações sobre a electricidade faz importantes descobertas: estuda a acção mútua entre ímans e correntes; experimenta a mútua influência entre fios condutores paralelos; distingue entre a quantidade de corrente que passa por um condutor e a força impulsora ou tensão; concebe o solenóide; antecipa-se ao galvanómetro, sugere como medir as correntes determinando o desvio aplicado a um íman; e propõe que o magnetismo é um fenómeno produzido pelo movimento de cargas na matéria, com o que se adianta notavelmente à teoria electrónica da matéria.

Site Map #2H. Magnetic Fields History Until 1820, the only magnetism known was that of iron magnets and of "lodestones", natural magnets of iron-rich ore. It was believed that the inside of the Earth was magnetized in the same fashion, and scientists were greatly puzzled when they found that the direction of the compass needle at any place slowly shifted, decade by decade, suggesting a slow variation of the Earth's magnetic field. How can an iron magnet produce such changes? Edmond Halley (of comet fame) ingeniously proposed that the Earth contained a number of spherical shells, one inside the other, each magnetized differently, each slowly rotating in relation to the others. Edmond Halley Hans Christian Oersted Hans Christian Oersted was a professor of science at Copenhagen University. In 1820 he arranged in his home a science demonstration to friends and students. He planned to demonstrate the heating of a wire by an electric current, and also to carry out demonstrations of magnetism, for which he provided a compass needle mounted on a wooden stand. While performing his electric demonstration, Oersted noted to his surprise that every time the electric current was switched on, the compass needle moved. He kept quiet and finished the demonstrations, but in the months that followed worked hard trying to make sense out of the new phenomenon.

Al conjunto de técnicas de emisión de ondas hertzianas que permiten la transmisión de la palabra y de los sonidos se le denomina: Radiodifusión El principio de la comunicación por radio: Un transmisor de radio produce una radiación electromagnética concentrada de una determinada frecuencia, siendo recogida por una antena. De todas las ondas que entran en contacto con ella, el receptor tan solo amplificará las que esten sintonizadas con él. Para llegar a este concepto numerosas personas debieron pasarse años experimentando. Todos ellos han aportado algo a la radiodifusión.

Ampere , Andre-Marie French physicist and mathmatician who founded the science of electrodynamics. He discovered that an electric current through a coil acts like a magnet. This discovery led to the invention of the alvanometer, an instrument for detecting and measuring electric currents. With the alvanometer he proved that electric current makes a circuit through a battery. The ampere, a unit used to measure the rate of flow of an electric current, is named after him. www link : From the University of St. Andrews, Scotland Ampere biography Babbage , Charles English mathematician and inventor who invented the principle of the analytical engine, the forerunner of the computer. The idea of mechanically calculating mathematical tables occured to Babbage around 1812. Later he made he calculator that could tabulate mathematical computations to eight decimals. In 1834 he envisioned the capability of performing any mathmatical operation by instruction from punched cards, a memory element in which to store numbers, and most of the other characteristics displayed by modern computers. (See also Ada Byron in special lifelines for famous women) A shortage of funds prevented him from building his machine, but a mechanical calculator based on his ideas was built in Sweden in 1855 by Scheutz. A real computer, however, had to await the electronic age.

Contact Back Next Home The New Science of Electrodynamics - 1820 André-Marie Ampère (1775 - 1836) André-Marie Ampère Ampère was present at the Académie des Sciences on Sept. 11, 1820, when François Arago performed - for the first time in France - Hans Christian Oersted’s experiment demonstrating the magnetic effects of current-carrying wires on magnetized needles. Inspired by Oersted’s discovery, Ampère immediately concluded that magnetism was electricity in motion, an intuitive leap which he sought to confirm by experiment. During September and October 1820, Ampère per-formed a series of experiments designed to elucidate the exact nature of the relationship between electric current-flow and magnetism, as well as the relationships governing the behavior of electric currents in various types of conductors. His investigations, reported weekly before the Académie des Sciences, established the new science of electrodynamics. Mémoire présenté à l’Académie royale des sciences Annales de Chimie tome XV André-Marie Am père Ampère’s most detailed report on the events of September and October 1820 was published as a lengthy two-part memoir in the Annales de Chimie et de Physique. Written hurriedly and in disjointed segments, it is a rich source of information in spite of its chronological errors. . . .” (Hofmann, p. 238). Among the discoveries described in this memoir are Ampère’s demonstration of the tangential orientation of a magnetic needle by an electric current when terrestrial magnetism is neutralized; his proof that conducting planar spirals attract and repel each other and respond to bar magnets in an analogy to magnetic poles; and his demonstration of electrodynamic forces between linear conducting wires. The memoir’s plates illustrate the several instruments that Ampère devised to carry out his experiments (see below).

20. Ampere, Andre Marie ampere, Andre Marie. Andre ampere (17751836) was a French physicistwho laid the foundations for the science of electrodynamics http://historia.et.tudelft.nl/wggesch/geschiedenis/personen/ampere/

Ampere, Andre Marie Andre Ampere (1775-1836) was a French physicist who laid the foundations for the science of electrodynamics through his demonstration that electric currents produce magnetic fields, and through his subsequent investigation into the relationship between these two phenomena. The son of a well-to-do merchant, Ampere educated himself through diligent reading in the family library. He survived the French Revolution to become a science teacher, first in Lyons and then in Bourg. He later took a post at the Ecole Polytechnique, and in 1808 became inspector general of the university system in Paris. Beginning in 1824, he also taught physics at the College de France and philosophy at the Faculte des Lettres, pursuing diverse scientific interests in the midst of personal tragedy. He was greatly affected by his father's execution by guillotine during the Revolution and, after his first wife's early death, had a catastrophic second marriage. Ampere's most notable achievements were his independent determination (1814) of Avogadro's law and his work from 1820 to 1827 based on Oersted's discovery, announced in 1820, that a magnetic needle moves in the vicinity of an electric current. Ampere succeeded in explaining the latter phenomenon by assuming that an electric current is capable of exciting a magnetic field. He further demonstrated that the direction of the magnetic field is determined by the direction of the current. He developed a quantitative relationship for the strength of a magnetic field in relation to an electric current (Ampere's theorem) and propounded a theory as to how iron becomes magnetized. Ampere also devised a rule governing the mutual interaction of current-carrying wires (Ampere's law) and produced a definition of the unit of measurement of current flow, now known as the ampere.
