Laplace's demon. In the history of science, Laplace's demon was a notable published articulation of causal determinism on a scientific basis by Pierre-Simon Laplace in 1814. [1] According to determinism, if someone (the demon) knows the precise location and momentum of every atom in the universe, their past and future values for any given time ...
Laplace's demon – Hypothetical all-knowing being who knows the precise location and momentum of every atom in the universe, and therefore could use Newton's laws to reveal the entire course of cosmic events, past and future. Pierre-Simon Laplace based the demon on the philosophical proposition of causal determinism.
Pierre-Simon, Marquis de Laplace ( / ləˈplɑːs /; French: [pjɛʁ simɔ̃ laplas]; 23 March 1749 – 5 March 1827) was a French scholar and polymath whose work was important to the development of engineering, mathematics, statistics, physics, astronomy, and philosophy.
Demonology is the study of demons within religious belief and myth. Depending on context, it can refer to studies within theology, religious doctrine, or occultism. In many faiths, it concerns the study of a hierarchy of demons. Demons may be nonhuman, separable souls, or discarnate spirits which have never inhabited a body.
Laplace transform. In mathematics, the Laplace transform, named after Pierre-Simon Laplace ( / ləˈplɑːs / ), is an integral transform that converts a function of a real variable (usually , in the time domain) to a function of a complex variable (in the complex-valued frequency domain, also known as s-domain, or s-plane ).
The Testament of Solomon is a pseudepigraphical work, purportedly written by King Solomon, in which the author mostly describes particular demons who he enslaved to help build the temple, the questions he put to them about their deeds and how they could be thwarted, and their answers, which provide a kind of self-help manual against demonic activity.
Historical application to the sunrise problem. Laplace used the rule of succession to calculate the probability that the Sun will rise tomorrow, given that it has risen every day for the past 5000 years. One obtains a very large factor of approximately 5000 × 365.25, which gives odds of about 1,826,200 to 1 in favour of the Sun rising tomorrow.
Laplace expansion. In linear algebra, the Laplace expansion, named after Pierre-Simon Laplace, also called cofactor expansion, is an expression of the determinant of an n × n - matrix B as a weighted sum of minors, which are the determinants of some (n − 1) × (n − 1) - submatrices of B. Specifically, for every i, the Laplace expansion ...
