Young–Laplace equation
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: Carl Friedrich Gauss unified the work of Young and Laplace in 1830. Gauss derived both the differential equation and boundary conditions using Johann Bernoulli's virtual work principles.
