Étienne PascalÉtienne Pascal (French:; 2 May 1588 – 24 September 1651) was a French chief tax officer and the father of Blaise Pascal (1623–1662). BiographyPascal was born in Clermont to Martin Pascal, the treasurer of France, and Marguerite Pascal de Mons. He had three daughters, two of whom survived past childhood: Gilberte (1620–1687) and Jacqueline (1625–1661). His wife Antoinette Begon died in 1626.
Probability theoryProbability theory or probability calculus is the branch of mathematics concerned with probability. Although there are several different probability interpretations, probability theory treats the concept in a rigorous mathematical manner by expressing it through a set of axioms.
Pierre de FermatPierre de Fermat (; French:; 17 August 1601 – 12 January 1665) was a French magistrate, polymath, and mathematician credited for early developments that led to infinitesimal calculus, including his technique of adequality. In particular, he is recognized for his discovery of an original method of finding the greatest and the smallest ordinates of curved lines, which is analogous to that of differential calculus, then unknown, and his research into number theory.

René DescartesRené Descartes ( , also ; French:; 31 March 1596 – 11 February 1650) was a French philosopher, mathematician, and scientist whose work was foundational to mathematics and modern philosophy. He connected the previously separate fields of geometry and algebra into analytic geometry and introduced a systematic method of inquiry that became influential in early modern philosophy.
Conic sectionA conic section, conic or a quadratic curve is a curve obtained from a cone's surface intersecting a plane. The three types of conic section are the hyperbola, the parabola, and the ellipse; the circle is a special case of the ellipse, though it was sometimes considered a fourth type. The ancient Greek mathematicians studied conic sections, culminating around 200 BC with Apollonius of Perga's systematic work on their properties.
Scientific methodInterplay between observation, experiment, and theory in scienceFor other uses, see Scientific method (other). The scientific method is an empirical method for acquiring knowledge through careful observation, rigorous skepticism, hypothesis testing, and experimental validation. Developed from ancient and medieval practices, it acknowledges that cognitive assumptions can distort the interpretation of the observation.
PascalineThe Pascaline (also known as the arithmetic machine or Pascal's calculator) is a mechanical calculator invented by Blaise Pascal in 1642. Pascal was led to develop a calculator by the laborious arithmetical calculations required by his father's (Étienne Pascal) work as the supervisor of taxes in Rouen, France. He designed the machine to add and subtract two numbers and to perform multiplication and division through repeated addition or subtraction.FluidIn physics, a fluid is a liquid, gas, or other material that may continuously move and deform (flow) under an applied shear stress, or external force. They have zero shear modulus, or, in simpler terms, are substances which cannot resist any shear force applied to them.
RouenRouen (UK: , US: ; French: [ʁwɑ̃] or [ʁu.ɑ̃]) is a city on the River Seine, in northwestern France. It is in the prefecture of region of Normandy and the department of Seine-Maritime. Formerly one of the largest and most prosperous cities of medieval Europe, the population of the metropolitan area (French: aire d'attraction) is 715,239 (2023). People from Rouen are known as Rouennais. Rouen was the seat of the Exchequer of Normandy during the Middle Ages.
Projective geometryType of geometry In mathematics, projective geometry is the study of geometric properties that are invariant with respect to projective transformations. This means that, compared to elementary Euclidean geometry, projective geometry has a different setting (projective space) and a selective set of basic geometric concepts.
Child prodigyA child prodigy is, technically, a child under the age of 10 who produces meaningful work in some domain at the level of an adult expert. The term is also applied more broadly to describe young people who are extraordinarily talented in some field. The term wunderkind (from German Wunderkind'wonder child') is sometimes used as a synonym for child prodigy, particularly in media accounts.
