unusual facts about Laplace's demon


Laplace's demon

The limit is based on the maximum entropy of the universe, the speed of light, and the minimum amount of time taken to move information across the Planck length, and the figure was shown to be about 10120 bits.


Battle of Ky Hoa

Charner's squadron, the most powerful French naval force seen in Vietnamese waters before the creation of the French Far East Squadron on the eve of the Sino-French War (August 1884–April 1885), included the steam frigates Impératrice Eugénie and Renommée (Charner and Page's respective flagships), the corvettes Primauguet, Laplace and Du Chayla, eleven screw-driven despatch vessels, five first-class gunboats, seventeen transports and a hospital ship.

Earth's orbit

Mathematicians and astronomers (such as Laplace, Lagrange, Gauss, Poincaré, Kolmogorov, Vladimir Arnold, and Jürgen Moser) have searched for evidence for the stability of the planetary motions, and this quest led to many mathematical developments, and several successive 'proofs' of stability for the solar system.

Laplace transform

The wide and general applicability of the Laplace transform and its inverse is illustrated by an application in astronomy which provides some information on the spatial distribution of matter of an astronomical source of radiofrequency thermal radiation too distant to resolve as more than a point, given its flux density spectrum, rather than relating the time domain with the spectrum (frequency domain).

Laplace–Runge–Lenz vector

The hydrogen atom is a Kepler problem, since it comprises two charged particles interacting by Coulomb's law of electrostatics, another inverse square central force.

Laplace–Stieltjes transform

The Laplace–Stieltjes transform, named for Pierre-Simon Laplace and Thomas Joannes Stieltjes, is an integral transform similar to the Laplace transform.

Laplace's law

Young–Laplace equation, describing pressure difference over an interface in fluid mechanics.

Biot–Savart law, in electromagnetics, it describes the magnetic field set up by a steady current density.

Rule of succession, a smoothing technique accounting for unseen data.

Maxwell's demon

The March 2011 issue of Scientific American features an article by Professor Mark G. Raizen of the University of Texas, Austin which discusses the first realization of Maxwell's demon with gas phase particles, as originally envisioned by Maxwell.

The demon is mentioned several times in The Cyberiad, a series of short stories by the noted science fiction writer Stanisław Lem.

Puerta de Hierro, el exilio de Perón

Laplace had previously played Perón at the movie Eva Perón: The True Story, the theater play "Borges y Perón" and the telenovela Padre Coraje.

Robert de Lamanon

They perfected their studies in Paris and there met the most famous scholars of the era : Laplace, Jussieu, d'Alembert, the Monge brothers, Volney, Malesherbes, and Condorcet, secretary of the Académie des sciences.

Yu-Chi Ho

Before Kalman, time series analysis and classical control theory studied the frequency domain, using harmonic analysis, especially Laplace and Fourier transforms.
