**Poisson**in a series of memoirs published in 1821 and later. - 4
**Poisson**assumed the existence of two dissimilar magnetic fluids, any element of which acted upon any other distant element in accordance with Coulomb's law of the inverse square, like repelling and unlike attracting one another. - On this hypothesis
**Poisson**investigated the forces due to bodies magnetized in any manner, and also originated the mathematical theory of magnetic induction. - The mathematical theory which was constructed by
**Poisson**, and extended and freed from doubtful hypotheses by Kelvin, has been elaborated by other investigators, notably F. **Poisson**, Mem.**Poisson**in a paper read on the 10th of June 1808, was once more attacked by Lagrange with all his pristine vigour and fertility of invention.- Resuming the inquiry into the invariability of mean motions,
**Poisson**carried the approximation, with Lagrange's formulae, as far as the squares of the disturbing forces, hitherto neglected, with the same result as to the stability of the system. - He proposed to apply the same principles to the calculation of the disturbances produced in the rotation of the planets by external action on their equatorial protuberances, but was anticipated by
**Poisson**, who gave formulae for the variation of the elements of rotation strictly corresponding with those found by Lagrange for the variation of the elements of revolution. **Poisson**brought forward as an objection to Fresnel's theory that it required at the centre of a circular shadow a point as bright as if no obstacle were intervening.**Poisson**, although previously demonstrated by Laplace for the case when p=0.- The
**Poisson**equation cannot, however, be applied in the above form to a region which is partly within and partly without an electrified conductor, because then the electric force undergoes a sudden change in value from zero to a finite value, in passing outwards through the bounding surface of the conductor. - Hence if we remove the charge -q at B and distribute electricity over the surface PO with a surface density a, according to the Coulomb-
**Poisson**law, a = qAO/21rAP3, the field of force to the left of PD will fulfil the required boundary conditions, and hence will be the law of distribution of the induced electricity in the case of the actual plate. - The last of the three supplements to his Traite des fonctions elliptiques was published in 1832, and
**Poisson**in his funeral oration remarked: " M. **Poisson**; the flow of electromagnetic waves along wires (Sir J.- (Euprepes) vittata, the "
**poisson**de sable" of Algeria, is semi-aquatic. Chalcides s. - 1827), And Adolphe
**Poisson**(B. **Poisson**published his Memoir on the Deviations of the Compass caused by the Iron in a Vessel.**Poisson**, F.- SIMEON DENIS
**POISSON**(1781-1840), French mathematician, was born at Pithiviers in the department of Loiret, on the 21st of June 1781. - His father, Simeon
**Poisson**, served as a common soldier in the Hanoverian wars; but, disgusted by the ill-treatment he received from his patrician officers, he deserted. **Poisson**was first sent to an uncle, a surgeon at Fontainebleau, and began to take lessons in bleeding and blistering, but made little progress.- Billy, who, when he speedily found that his pupil was becoming his master, devoted himself to the study of higher mathematics in order to follow and appreciate him, and predicted his future fame by the punning quotation from Lafontaine': - "Petit
**Poisson**deviendra grand Pourvu que Dieu lui prete vie." - This success at once procured for
**Poisson**an entry into scientific circles. - Laplace, in whose footsteps
**Poisson**followed, regarded him almost as his son. - His father, whose early experiences led him to hate aristocrats, bred him in the stern creed of the first republic. Throughout the empire
**Poisson**faithfully adhered to the family principles, and refused to worship Napoleon. - As a teacher of mathematics
**Poisson**is said to have been more than ordinarily successful, as might have been expected from his early promise as a repetiteur at the Ecole Polytechnique. - (1827), &c. In the first of these memoirs
**Poisson**discusses the famous question of the stability of the planetary orbits, which had already been settled by Lagrange to the first degree of approximation for the disturbing forces. **Poisson**showed that the result could be extended to a second approximation, and thus made an important advance in the planetary theory.**Poisson**made important contributions to the theory of attraction.- Besides his many memoirs
**Poisson**published a number of treatises, most of which were intended to form part of a great work on mathematical physics, which he did not live to complete. - Arago, Biographie de
**Poisson**, read before the Academie des Sciences on the 16th of December 1850. - The French mathematicians, Coulomb, Biot,
**Poisson**and Ampere, had been content to accept the fact that electric charges or currents in conductors could exert forces on other charges or conductors at a distance without inquiring into the means by which this action at a distance was produced. - James Clerk Maxwell (1831-1879) entered on his electrical studies with a desire to ascertain if the ideas of Faraday, so different from those of
**Poisson**and the French mathematicians, could be made the foundation of a mathematical method and brought under the power of analysis.3 Maxwell started with the conception that all electric and magnetic phenomena are due to effects taking place in the dielectric or in the ether if the space be vacuous. - This fact and hypothesis brought electrical phenomena within the domain of mathematical analysis and, as already mentioned, Laplace, Biot,
**Poisson**, G. **Poisson**, he received the appointment of secretary to the Observatory of Paris.- Fresnel's arguments in favour of that theory found little favour with Laplace,
**Poisson**and Biot, the champions of the emission theory; but they were ardently espoused by Humboldt and by Arago, who had been appointed by the Academy to report on the paper. - In 1831 Simeon Denis
**Poisson**published his Nouvelle Theorie de action capillaire. - On these assumptions his results are certainly right, and are confirmed by the independent method of Gauss, so that the objections raised against them by
**Poisson**fall to the ground. - But whether the assumption of uniform density be physically correct is a very different question, and
**Poisson**rendered good service to science in showing how to carry on the investigation on the hypothesis that the density very near the surface is different from that in the interior of the fluid. - We have given several examples in which the density is assumed to be uniform, because
**Poisson**has asserted that capillary B (25) e = c p (X' - 4 7rpe (0) ) -I-474°o(z)dz. **Poisson**,' Goldschmidt, 2 L.**Poisson**in the chair of mechanics in the Faculte des Sciences at Paris.
