Bernoulli's law

   Also found in: Medical, Financial, Encyclopedia, Wikipedia 0.01 sec.
Ber·noul·li's law  (br-nlz)
[After Jakob Bernoulli.]

Bernoulli's law  (br-nlz)
1. A law of fluid mechanics stating the relationship between the velocity, density, and pressure of a fluid. Mathematically, the law states that P + 1/2 v2 = constant, where P is the pressure (in newtons per square meter), is the density of the fluid (in kilograms per square meter), and v is the velocity (in meters per second). If no energy is added to the system, an increase in velocity is accompanied by a decrease in density and/or pressure. The law is directly related to the principle of conservation of energy. See also Bernoulli effect.

That's not to say moral precepts don't often include conventions that are partly subjective--matters of fashion and culture, like dress codes or the rule about driving on the left side in England; but at their core is bedrock that stands on its own--abstract rules emerging from the interaction of individuals, much as Bernoulli's laws emerge from the interaction of molecules in a fluid or a gas--and are therefore quite as objective.
