Nationality: French
Most Famous for: Laplace Equation and Laplace Transforms
Pierre-Simon Laplace was a mathematician and astronomer of French origin. His pioneering work included the theory of probability and statistics. This study can be defined as the use of numbers and mathematical formulae to calculate the chance of an event occurring. The ability to get such numbers helps in predicting trends and outcomes. Laplace’s work also included various studies on the solar system, with the focus being on its stability. His work earned him the title the ‘French Newton.’ Pierre was born into a low-income family, prompting the need for neighbors to fund his education. He was sent to study theology at 16, but developed interest at mathematics and his journey in science began.
Early life
Pierre-Simon Laplace was born in Normandy, France, on the 23rd of March, 1749. His father was a farmer. His educational costs were footed by wealthy neighbors who stepped in to intervene in the schooling of this brilliant mind. It was his father’s idea to send him to study theology at 16, as he wanted his son to be part of the Roman Catholic Church. With the development of his interest in mathematics, at 19 he quit the C

Laplace's demon
Hypothetical all-predicting intellect
This article is about the concept. For the game, see Laplace no Ma. For the statistical software package, see LaplacesDemon.
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 are entailed; they can be calculated from the laws of classical mechanics.[2]
Discoveries and theories in the decades following suggest that some elements of Laplace's original writing are wrong or incompatible with our universe. For example, irreversible processes in thermodynamics suggest that Laplace's "demon" could not reconstruct past positions and moments from the current state: A metal rod heated at one end will equilibrate to the same end temperature across the bar regardless of which side was initially heated; reconstructing the initial state from the final state is therefore impossible as multiple initial states all share the same final state.
