Young-Laplace

In physics, the Young–Laplace equation is a nonlinear partial differential equation that describes the capillary pressure difference sustained across the interface between two static fluids, such as water and air, due to the phenomenon of surface tension or wall tension, although usage on the latter is only applicable if assuming that the wall is very thin. The Young–Laplace equation relates the pressure difference to the shape of the surface or wall and it is fundamentally important in the study of static capillary surfaces. It is a statement of normal stress balance for static fluids meeting at an interface, where the interface is treated as a surface (zero thickness):

where is the pressure difference across the fluid interface, γ is the surface tension (or wall tension), is the unit normal pointing out of the surface, is the mean curvature, and and are the principal radii of curvature. (Some authors[who?] refer inappropriately to the factor as the total curvature.) Note that only normal stress is considered, this is because it can be shown that a static interface is possible only in the absence of tangential stress.

The equation is named after Thomas Young, who developed the qualitative theory of surface tension in 1805, and Pierre-Simon Laplace who completed the mathematical description in the following year. It is sometimes also called the Young–Laplace–Gauss equation, as Gauss unified the work of Young and Laplace in 1830, deriving both the differential equation and boundary conditions using Johann Bernoulli's virtual work principles.

LaPlace man booked with cruelty to young son who knocked over TV | NOLA.com

Deputies from the St. John the Baptist Parish Sheriff's Office have arrested a LaPlace man on suspicion of striking his 4-year-old son and bursting his eardrum, according to authorities. Kerry Clofer, 21, of 1612 Yorktowne Drive was booked with cruelty to a juvenile after evidence suggested he hit his son for knocking over a television. "The boy had bruises around the left ear, and after a physical examination, it was learned he sustained a busted eardrum," said Capt. Dane Clement, a Sheriff's Office spokesman. On Feb. 7, Clofer picked up his son from the boy's mother for a weeklong custody stay, Clement said. When the boy's mother picked the child up from school later that week, teachers at the school informed her about the boy's injuries, Clement said. St. John deputies met with the mother of the 4-year-old Garyville boy, and she said her son suffered injuries while in the custody of his father, Clement said. "When the boy was asked how he was hurt, he said he got in trouble at his daddy's house for knocking over the television, and his dad hit him," Clement said. After an investigation by St. John detectives, an arrest warrant was issued...

yovisto blog: Pierre Simon de Laplace and his true love for Astronomy and Mathematics

On March 28, 1749, French mathematician and astronomer Pierre Simon marquise de Laplace was born, whose work was pivotal to the development of mathematical astronomy and statistics. One of his major achievements was the conclusion of the five-volume Mécanique Céleste (Celestial Mechanics) which translated the geometric study of classical mechanics to one based on calculus, opening up a broader range of problems.
