Carlene Hutchins (1911-2009) was a leading researcher in the study of violin acoustics, with over a hundred publications in the field. Great 19th-century mathematicians, including Ernst Chladni and Sophie Germain, had investigated how waves form on thin plates when different kinds of vibrations are applied. Some interpret Gauss' lack of intervention in Germain's education and eventual silence as a personal Napoleon offered another cash prize of 3000 francs to any mathematician who could write the acoustic formula. When, in 1816, the third and final contest was held, a paper bearing her own name and treating vibrations of general curved as well as plane elastic surfaces was awarded the grand prize—the high point in her scientific career. Revolution began, and, although her father served in the revolutionary legislative assembly, the tumultuous events of 1789 took their toll on Sophie.

Germain died childless and unmarried, of untreatable breast cancer on June 27, 1831 in Paris. Also, while the Gaussian curvature completely characterizes the local metric geometry of a surface, the mean cruvature is more suitabe for applications in elasticity theory. Germain, Sophie Sophie Germain was a French mathematician. mechanics, celestial mecahanics, astronomy, mathematics. Nationality: French. When she was thirteen, she was in her father's study reading a copy of History of Mathematics. Biography Marie-Sophie Germain was the middle daughter of Ambroise-François Germain (1726-1821), a prosperous merchant, goldsmith and jeweller who later became a silk-merchant, and Marie-Madeleine Gruguelu (?-1823) the daughter of the goldsmith Jean Gruguelu who was a friend of philosophers and political economists. This had been done by Szabo/ according to Sophie Germain in his above mentioned book on mechanics; in chapter IV (History of the linear theory of elasticity for homogenous and isotropic materials), part D (History of the theory of thin shells) there are 8 sections in relation to this subject beginning with (2) the acoustics by Ernst Florens . From the ages of 13 to 18 Sophie, as she was called to minimize confusion with the other Maries in her immediate Hence 4/S2 = 0 in Germain’s differential equation, and it reduces to the equation which she and Lagrange had derived for the vibration of flat plates. The subterfuge was eventually abandoned, and Germain found an excellent mentor and teacher. rejection of her. French mathematician who did important work on Fermat's last theorem, proving it for any primes less than 100 under certain assumptions (and, in particular, for Sophie Germain primes. Germain never formally attended any school or gained a degree during her entire life, but she was allowed to read lecture notes circulated in the Ecole Polytechnique. The group in-house expertise includes innovative systems and solutions devoted to inertial navigation, subsea positioning, underwater imaging . She came from a wealthy family and was educated at home. So great was Lagrange's respect for the work of "le Blanc" that he sought out the mystery man and, when he discovered that le Blanc was a woman, he extolled her abilities. Among Sophie Germain’s scientific writings are Remarques sur la nature, les bornes et l’étendue de la questuib des surfaces élastuiques et équation gvénérale de ces surfaces (Paris, 1826); Mémoire sur la courbure des surfaces (Paris, 1830); Oeuvers philosophique de Sophie Germain (Paris, 1879); and mémoire sur l’emploi de l’épaisseur dans la théorie des surfaces élastiques (Paris, 1880). Found inside – Page 12Sophie Germain wrote a fourth-order equation to describe plate vibrations, and thus won a prize provided by the French emperor Napoleon, although Kirchhoff later gave a more accurate treatment of the boundary conditions. One of her most important results in number theory was her work on an unsolved problem called Fermat's Last Theorem: "Sophie Germain's foundational work on Fermat's Last Theorem, a problem unsolved in mathematics into the late 20th century, stood unmatched for over one hundred years." ("Sophie Germain," Notable). . The French Academy of Sciences awarded her a prize for a paper on the patterns produced by vibration. Unlike her female predecessors and contemporaries, Sophie Germain was an impressive mathematician and made lasting contributions to both number theory and the theories of plate vibrations and elasticity. Among these was a limited proof of Fermat's Last Theorem, her best known contribution to mathematics. He was stounded at its originally, praised it publicly, sought out its author, and thus discovered that M. Le Blanc was Mlle. Sophie Germain's answer, although rejected due to flaws, was the only entry with the correct approach. Women in Science .

In this period, Sophie Germain also started corresponding with Gauss, again under pseudonym, who admired her courage and intelligence. In 1813 the Academy reopened the contest, and Sophie Germain offered a revised paper which included the question of experimental verification. Thierry a 4 postes sur son profil. Next to mathematics, the young woman also started to teach herself in Greek and Latin in order to understand the works of Newton and Euler. At that time, the learned community in Paris was once again vibrant, spurred by the support of Napoléon. When the École Polytechnique opened in 1794, even though women were not allowed to attend as regular students, Germain obtained lecture notes for courses and submitted papers using the pseudonym M.

Sophie Germain. When a 13-year old Marie-Sophie Germain was stuck in the house because of the chaotic revolution on the streets of Paris in 1789, she found a refuge . However, she managed to study the lecture notes and started sending own works to the faculty member Joseph Louis Lagrange [7] under the name of a former student. Her father was for a time deputy to the State-General (later the Constituent Assembly). Gauss had arranged for her to receive an honorary doctorate from the University of Göttingen in Germany, but she died before it could be awarded. Moncrief, J.

On June 27, 1831, French mathematician, physicist, and philosopher Marie-Sophie Germain passed away. She is best known for her work in number theory and contributions to the applied mathematics of acoustics and elasticity. She wrote a mathematical explanation involving wave-like functions to describe how sound created the geometric patterns. She was welcomed as a marvel and used as a muse by the likes of Jean B. Fourier and Augustin-Louis Cauchy, but her contacts did not develop into the sort of long-term apprenticeship that would have compensated for her lack of access to formal education and university-class libraries.
