The LAPLACE (Laplace) Pierre Simon (1749-1827), the French astronomer, mathematician, physics, the foreign honorary member Petersburg AN (1802). The writer of classical transactionses on a theory of probabilities and a gravitational astronomy (dynamics of the Solar system as a whole and its resistance, etc.): compositions " the Analytical theory of probabilities " (1812) and " the Tract about a gravitational astronomy " (t. 1-5, 1798-1825); it is a lot of transactionses on differential equations, mathematical physics, the theory of a capillarity, heat, soundman, a geodesy, etc. Has offered (1796) cosmogonic hypothesis (a hypothesis of the Laplace). The classical representative of a mechanistic determinism.

The LAPLACE the LAW, content P.Laplasom (1806) relation????? - a capillary pressure?? From average curvature E of interface of adjoining phases (napr., waters and air in a capillary) and surface tension?.

The LAPLACE the OPERATOR, the linear differential operator, which functions? (x, y, z) puts in correspondence funktsijuVstrechaetsja in many problems of mathematical physics (an illumination, heat, motion of a theoretical incompressible liquid). An equation??? 0 calls the Laplace as an equation.

The LAPLACE the THEOREM, one of limiting theorems of a theory of probabilities. If at each of n independent tests the probability of occurrence of some random event E is peer r (0

The LAPLACE the EQUATION, a differential equation with partial derivatives of 2-nd porjadkagde, x, y, z - explanatory variables? (x, y, z) - required function. It is considered by P.Laplasom (1782). In an equation of the Laplace result many problems of mathematical physics (napr., distribution of temperatures in a stable process).

LAPORT (Laporte) Otto (1902-71), American physics. The native of Germany, with 1924 - in the USA. Transactionses on atomic spectrum analysis, mechanics of a liquid, physics of heats. Has found (1924), that in the composite atoms energy levels can be even and odd, and emitting of a photon always results in such transitions at which the odd level passes in even (rule Laporta). This rule has preceded to a spatial parity conservation law discovered by J.Vignerom.

LAPORT (Laporte) to the Erysipelas (r. 1925), the French prose writer.
