Vor 13 Stunden · In statistical physics, the kinetic theory of gases applies Newton's laws of motion to large numbers (typically on the order of the Avogadro number) of particles. Kinetic theory can explain, for example, the pressure that a gas exerts upon the container holding it as the aggregate of many impacts of atoms, each imparting a tiny amount of momentum.
Vor 4 Tagen · In probability theory, the central limit theorem ( CLT) states that, under appropriate conditions, the distribution of a normalized version of the sample mean converges to a standard normal distribution. This holds even if the original variables themselves are not normally distributed.
Vor 4 Tagen · In physics, Lagrangian mechanics is a formulation of classical mechanics founded on the stationary-action principle (also known as the principle of least action). It was introduced by the Italian-French mathematician and astronomer Joseph-Louis Lagrange in his presentation to the Turin Academy of Science in 1760 [1] culminating in ...
Vor 5 Tagen · Außerdem beschreibt die Magnetostatik die Kraftwirkung derartig erzeugter Felder auf Magnete und Ströme. Hierzu gehört das Verhalten eines magnetischen Dipols in einem zeitlich konstanten Magnetfeld, beispielsweise das Verhalten einer (frei beweglichen) Magnetnadel im Erdmagnetfeld. Die Grundbegriffe sind der Elektrostatik analog.
Vor 4 Tagen · Covering various areas of mathematical and theoretical physics, including quantum gravity, cosmology, string theory, biophysics, nonequilibrium physics, statistical mechanics and quantum many-body theory.
Vor 4 Tagen · Enrico Fermi, Italian-born American scientist who was one of the chief architects of the nuclear age. He developed the mathematical statistics for a large class of subatomic phenomena, explored nuclear transformations caused by neutrons, and directed the first controlled chain reaction involving nuclear fission.
