  • Simeon Denis Poisson English Version
    SIMÉON DENIS POISSON (June 21, 1781 – April 25, 1840) by HEINZ KLAUS STRICK, Germany In the period before the French Revolution, those in France who did not belong to the nobility had a difficult time in establishing themselves in a professional career. Such a situation was experienced by SIMÉON DENIS POISSON’s father, who, following his service as a soldier in the army, had to be satisfied with a minor administrative position in the provinces. When the Revolution altered the existing power structures, he seized his chance and took over an administrative office in the regional government. (drawings © Andreas Strick) He then set out to take advantage of his new and influential position to secure the professional future of his son. He determined that a suitable career would be that of a surgeon, and so the fifteen-year-old SIMÉON was sent as an apprentice to a relative in Fontainebleau. But it was not long before it became clear that his son possessed neither an interest in medicine nor sufficient manual dexterity. Indeed, SIMÉON had considerable difficulty in physical coordination and could not possibly have been a suitable candidate for the career of a surgeon. As an interim solution, it was decided to send the boy to school. There, SIMÉON impressed his teachers with his eagerness to learn and his rapid progress, particularly in mathematics, so that they advised him to register for the admissions examination at the École Polytechnique, in Paris. And although he had had no systematic education, he passed the examination in 1798 with the year’s top score.

The Legacy of Henri Victor Regnault in the Arts and Sciences Sébastien Poncet , Laboratoire M2P2, France Laurie Dahlberg , Bard College Annandale, USA Abstract: The 21 st of July 2010 marked the bicentennial of the birth of Henri Victor Regnault, a famous French chemist and physicist and a pioneer of paper photography. During his lifetime, he received many honours and distinctions for his invaluable scientific contributions, especially to experimental thermodynamics. Colleague of the celebrated chemist Louis-Joseph Gay-Lussac (1778-1850) at the École des Mines and mentor of William Thomson (1824-1907) at the École Polytechnique, he is nowadays conspicuously absent from all the textbooks and reviews (Hertz, 2004) dealing with thermodynamics. This paper is thus the opportunity to recall his major contributions to the field of experimental thermodynamics but also to the nascent field, in those days, of organic chemistry.

  • La Jeunesse De Joseph Fourier À Auxerre (1768-1794) : Une Nouvelle Approche ?
    La jeunesse de Joseph Fourier à Auxerre (1768-1794) : une nouvelle approche ? Jean-Charles GUILLAUME L'image de Joseph Fourier (1768-1830) pendant les vingt-sept premières années de sa vie est bien connue. Il naît à Auxerre, ville qui « a un aspect moyenâgeux1 », un « air antique et triste […] presque toute bâtie en bois2 », « d’une famille pauvre, mais estimable3 », chez des parents qui « ne savent que très peu lire et écrire4 ». Cet orphelin à huit ou neuf ans est le fils « d’artisans pauvres et vertueux5 », « un vaillant jeune homme, sorti de cette classe ouvrière, laborieuse, si féconde en âmes fortes et d’une trempe vigoureuse [monté], par son seul mérite, aux premiers rangs de la société6 ». Plus tard, « amené sur un autre théâtre », celui de la Révolution, il est de ceux qui croient que « le meilleur moyen d’empêcher ce fleuve bienfaisant de devenir un torrent dévastateur, [c’est] que les hommes éclairés et vraiment patriotes [dirigent] son cours7 ». Son rôle à la Société populaire et au Comité de surveillance lui permet « d’empêcher beaucoup de mal et de faire un peu de bien8 », mais, un peu plus tard, celui à Orléans lui fait risquer la mort : « J’ai éprouvé tous les degrés de la persécution et du malheur. Aucun de mes adversaires n’a connu plus de danger et je suis le seul de mes compatriotes qui ait été condamné à mort. Cependant ils ont l’injustice d’oublier la terreur que j’ai éprouvée pour parler sans cesse de celle que j’ai dit-on inspiré.

  • Joseph Fourier
    On the Temperatures of the Terrestrial Sphere and Interplanetary Space Jean-Baptiste Joseph Fourier 1 Translator’s note. This is a translation of Jean-Baptiste Joseph Fourier’s ”M´emoiresur les Temp´eratures du Globe Terrestre et des Espaces Plan´etaires,” which originally appeared in M´emoires d l’Acad´emie Royale des Sciences de l’Institute de France VII 570-604 1827. The original text is most readily acces- sible in the 1890 edition of Fourier’s collected Oeuvres, Volume 2, edited by M. Gaston Darboux (Gauthier-Villars et Fils:Paris). This work is available online from the Biblioth`equeNationale de France (search catalogue.bnf.fr for author ”Fourier, Jean-Baptiste-Joseph”). In the version reprinted in the Oeuvres, it is noted that a very slightly different version of the essay also appeared in the Annales de Chimie et de Physique, vol XXVII, pp 136-167; 1824, under the title ”Remarques g´en´eralessur les temp´eratures du globe terrestre et des espaces plan´etaires.” An English translation of Fourier’s article has not been available in print for more than a century. Although the article is widely cited, it is my experience that its actual contents are not well known in the Anglophone community (and they are hardly better known among Francophones). My object in doing a new translation is to help rectify this situation, while using some of my own knowl- edge of physics of climate to help put Fourier’s arguments in the clearest possible light. I have put a premium on readability rather than literal translation, and in some cases I have taken the liberty of rephrasing some sentences so as to make Fourier’s reasoning more evident; I do not think that in doing so I have read more into the text than Fourier himself put there, but readers seeking the finer nuances of Fourier’s meaning will of course have to read the original.

  • Siméon Denis Poisson (1781 – 1840)
    Siméon Denis Poisson (1781 – 1840) From Wikipedia, the free encyclopedia, http://en.wikipedia.org/wiki/Sim%C3%A9on_Denis_Poisson !Siméon Denis Poisson was a French mathematician, geometer, and physicist. He obtained many important results, but within the elite Académie des Sciences he also was the final leading opponent of the wave theory of light and was proven wrong on that matter by Augustin-Jean Fresnel. Poisson was born in Pithiviers, Loiret, the son of soldier Siméon Poisson. In 1798, he entered the École Polytechnique in Paris as first in his year, and immediately began to attract the notice of the professors of the school, who left him free to make his own choices as to what he would study. In 1800, less than two years after his entry, he published two memoirs, one on Étienne Bézout's method of elimination, the other on the number of integrals of a finite difference equation. The latter was examined by Sylvestre-François Lacroix and Adrien-Marie Legendre, who recommended that it should be published in the Recueil des savants étrangers, an unprecedented honour for a youth of eighteen. This success at once procured entry for Poisson into scientific circles. Joseph Louis Lagrange, whose lectures on the theory of functions he attended at the École Polytechnique, recognized his talent early on, and became his friend (the Mathematics Genealogy Project lists Lagrange as his advisor, but this may be an approximation); while Pierre-Simon Laplace, in whose footsteps Poisson followed, regarded him almost as his son. The rest of his career, till his death in Sceaux near Paris, was almost entirely occupied by the composition and publication of his many works and in fulfilling the duties of the numerous educational positions to which he was successively appointed.

  • Fourier's Series Transcript
    Fourier's Series Transcript Date: Tuesday, 20 January 2015 - 1:00PM Location: Museum of London 20 January 2015 Fourier’s Series Professor Raymond Flood Slide: Title Thank you for coming to my first lecture of 2015 and a Happy New Year to you all! Today I want to talk about the French mathematician and physicist Jean Baptiste Joseph Fourier and the consequences of his mathematical investigations into the conduction of heat. He derived an equation, not surprisingly now called the heat equation, to describe the conduction of heat but more importantly an approach to solving the heat equation by using an infinite series of trigonometric functions, now called Fourier series. The ideas he introduced had major applications in other physical problems and also led to many of the most important mathematical discoveries of the nineteenth century. Slide: Overview Let me start my overview of the lecture by talking briefly about the situation in mathematics and its use in explaining and predicting the world about us at the end of the eighteenth century. During the eighteenth century many master mathematicians, for example Laplace and Lagrange, had built on Newtonian mechanics to describe and predict the motion of bodies on the earth and in the sky. They had the underlying equations for the motion of bodies, indeed they had them in various formulations and they investigated these equations mathematically. But the behaviour of heat, light, electricity and magnetism had yet to yield their governing equations and this lecture is about applying mathematics to one of these four areas namely heat. It was Joseph Fourier, the distinguished French mathematician, physicist, Egyptologist, demographer and public servant who tackled the conduction of heat and found the fundamental equations its conduction but as I’ve mentioned, just as importantly found new mathematical methods for solving these equations.

  • Jean Baptiste Joseph Fourier
    Jean Baptiste Joseph Fourier Born: 21 March 1768 in Auxerre, Bourgogne, France Died: 16 May 1830 in Paris, France Joseph Fourier's father was a tailor in Auxerre. After the death of his first wife, with whom he had three children, he remarried and Joseph was the ninth of the twelve children of this second marriage. Joseph's mother died went he was nine years old and his father died the following year. His first schooling was at Pallais's school, run by the music master from the cathedral. There Joseph studied Latin and French and showed great promise. He proceeded in 1780 to the École Royale Militaire of Auxerre where at first he showed talents for literature but very soon, by the age of thirteen, mathematics became his real interest. By the age of 14 he had completed a study of the six volumes of Bézout's Cours de mathématiques. In 1783 he received the first prize for his study of Bossut's Mécanique en général. In 1787 Fourier decided to train for the priesthood and entered the Benedictine abbey of St Benoit-sur-Loire. His interest in mathematics continued, however, and he corresponded with C L Bonard, the professor of mathematics at Auxerre. Fourier was unsure if he was making the right decision in training for the priesthood. He submitted a paper on algebra to Montucla in Paris and his letters to Bonard suggest that he really wanted to make a major impact in mathematics. In one letter Fourier wrote Yesterday was my 21st birthday, at that age Newton and Pascal had already acquired many claims to immortality.
