Capillarity
Capillary action (sometimes capillarity, capillary motion, capillary effect, or wicking) is the ability of a liquid to flow in narrow spaces without the assistance of, or even in opposition to, external forces like Gravitation, gravity. The effect can be seen in the drawing up of liquids between the hairs of a paint-brush, in a thin tube, in porous materials such as paper and plaster, in some non-porous materials such as sand and liquefied carbon fiber, or in a biological cell. It occurs because of intermolecular forces between the liquid and surrounding solid surfaces. If the diameter of the tube is sufficiently small, then the combination of surface tension (which is caused by Cohesion (chemistry), cohesion within the liquid) and Adhesion, adhesive forces between the liquid and container wall act to propel the liquid. History The first recorded observation of capillary action was by Leonardo da Vinci. A former student of Galileo Galilei, Galileo, Niccolò Aggiunti, was said ...

Louis Carré (mathematician)
Louis Carré (26 July 1663 – 17 April 1711) was a French people, French mathematician and member of the French Academy of Sciences. He was the author of one of the first books on integral calculus. This level of activity led to him being brought on as an Associate Mechanician on 15 February 1702 and being promoted to Pensioner on 18 August 1706. This provided him with an income which allowed him to devote himself entirely to his academic studies during the final five years of his life. At age 46 he suffered an attack of dyspepsia from which he died in 1711.. References

The vapor pressure at a convex curved surface is higher than that at a flat surface. The Kelvin equation is dependent upon thermodynamic principles and does not allude to special properties of materials. It is also used for determination of pore size distribution of a porous medium A porous medium or a porous material is a material containing (voids). The skeletal portion of the material is often called the "matrix" or "frame". The pores are typically filled with a ( or ).
