Hace 6 días · In particle physics, a magnetic monopole is a hypothetical elementary particle that is an isolated magnet with only one magnetic pole (a north pole without a south pole or vice versa). [1] [2] A magnetic monopole would have a net north or south "magnetic charge". Modern interest in the concept stems from particle theories, notably the grand ...

Im Jahre 1733 zeigte Abraham de Moivre in seiner Schrift The Doctrine of Chances im Zusammenhang mit seinen Arbeiten am Grenzwertsatz für Binomialverteilungen eine Abschätzung des Binomialkoeffizienten, die als Vorform der Normalverteilung gedeutet ...
Hace 5 días · A Fourier series ( / ˈfʊrieɪ, - iər / [1]) is an expansion of a periodic function into a sum of trigonometric functions. The Fourier series is an example of a trigonometric series, but not all trigonometric series are Fourier series. [2] By expressing a function as a sum of sines and cosines, many problems involving the function become ...
Hace 1 día · e. Loop quantum gravity ( LQG) is a theory of quantum gravity that incorporates matter of the Standard Model into the framework established for the intrinsic quantum gravity case. It is an attempt to develop a quantum theory of gravity based directly on Albert Einstein's geometric formulation rather than the treatment of gravity as a mysterious ...

Hace 2 días · t. e. In information theory, the entropy of a random variable is the average level of "information", "surprise", or "uncertainty" inherent to the variable's possible outcomes. Given a discrete random variable , which takes values in the set and is distributed according to , the entropy is. where denotes the sum over the variable's possible values.
