Economic calculation problem

The economic calculation problem (sometimes abbreviated ECP) is a criticism of using economic planning as a substitute for market-based allocation of the factors of production. It was first proposed by Ludwig von Mises in his 1920 article "Economic Calculation in the Socialist Commonwealth" and later expanded upon by Friedrich Hayek. In his first article, Mises described the nature of the price system under capitalism and described how individual subjective values (while criticizing other theories of value) are translated into the objective information necessary for rational allocation of resources in society.

Démonstration (logique et mathématiques)

vignette| : un des plus vieux fragments des Éléments d'Euclide qui montre une démonstration mathématique. En mathématiques et en logique, une démonstration est un ensemble structuré d'étapes correctes de raisonnement. Dans une démonstration, chaque étape est soit un axiome (un fait acquis), soit l'application d'une règle qui permet d'affirmer qu'une proposition, la conclusion, est une conséquence logique d'une ou plusieurs autres propositions, les prémisses de la règle.

Mathematical constant

A mathematical constant is a key number whose value is fixed by an unambiguous definition, often referred to by a special symbol (e.g., an alphabet letter), or by mathematicians' names to facilitate using it across multiple mathematical problems. Constants arise in many areas of mathematics, with constants such as e and pi occurring in such diverse contexts as geometry, number theory, statistics, and calculus. Some constants arise naturally by a fundamental principle or intrinsic property, such as the ratio between the circumference and diameter of a circle (pi).
