The subject of the screening effect against induction, due to sheets of different metals, was worked out mathematically by Horace Lamb and also by Charles Courx.

Fondness for figures, and a distaste for Latin grammar led him to the choice of a mercantile career. His talents excited the interest of Lagrange and Laplace. The present problems of dynamics differ materially from those of the last century. The solution of the problem of the general motion of an ellipsoid in a fluid is due to the successive labours of GreenClebschand Bjerknes The most important application of the theory of the long wave is to the explanation of tidal phenomena in rivers and estuaries.

Courbes paramétriques et équations différentielles pour la physique (Mat307-ex237)

For an ideally rigid earth the period would be days, but if as rigid as steel, it would bethe observed period being days. Nautical Almanac office has been to collect and discuss data for new tables of the planets which will supplant the tables of Le Verrier.

curvilignee In other languages Add links. But he gave no general solutions. A mathematical paper followed in on “the motion of fluids and solids relative to the earth’s surface.


The electro-magnetic theory has received developments from Lord Rayleigh, J. Rectangular and triangular membranes were shown by him to be connected with questions in the theory of numbers. Les calculs fastidieux ou techniques se feront directement sur ordinateur en TP ou sur calculatrices en TD avec un logiciel de calcul formel. Maxwell not only translated into mathematical language the experimental results of Faraday, but established the intdgrale theory of light, since verified experimentally by Hertz.

Maxwell predicted that so long as Boyle’s law is true, the coefficient of viscosity and the coefficient of thermal conductivity remain independent of the pressure. His results on torsion abound in beautiful graphic illustrations. Neumann and McCullagh assume the density uniform and the elasticity different in all substances. Thomson of Cambridge born in his classical treatise on the Motion of Vortex Ringsto which the Adams Prize was awarded in In electricity the mathematical theory and the measurements of Henry Cavendish —and in magnetism the measurements of Charles Augustin Coulomb —became the foundations for a system of measurement.

The determination of the period of oscillation of a rotating liquid spheroid has important bearings on the question of the origin of the moon. This construction was extended by Sylvester so as to measure the rate of rotation of the ellipsoid on the plane. He was called to Russia with Clapeyron and others to superintend the construction of bridges and roads.

This induced him to alter the very foundation of his kinetic theory of gases by assuming between the molecules a repelling force cruviligne inversely as the fifth power of their distances. Routh being Senior Wrangler.


If the earth is a solid, then its elasticity co-operates with gravity in opposing deformation due to the attraction of the sun and moon.

Peirce, who proved their non-solidity by showing that even an irregular solid ring could not be in equilibrium about Saturn. His researches on the theory of potential are epoch-making. He stated the rule for angles of contact between liquids and solids.

At eighteen he wrote a memoir on finite differences which was printed curvilgne the recommendation of Curviligme. Young’s explanations, not being verified by him by extensive numerical calculations, attracted little notice, and it was not until Augustin Fresnel cors applied mathematical analysis to a much greater extent than Young had done, that the undulatory theory began to carry conviction. Urbain Jean Joseph Le Verrier — of Paris wrote, the Recherches Astronomiquesconstituting in part a new elaboration of celestial mechanics, and is famous for his theoretical discovery of Neptune.

He deserves much credit for his derivation and transformation of the general elastic equations, and for his application of them to double refraction. Pour un guide plus complet, vous pouvez consulter pour le calcul formel http: The first suggestions of a kinetic theory of matter go back as far as the time of the Greeks.

A function of fundamental importance in the mathematical theories of electricity and magnetism is the “potential.

On peut aussi utiliser la transformation de Laplace et son inverse.
