Swiss family that produced many capable
mathematicians and scientists in the
17th, 18th, and 19th centuries, in particular
the brothers Jakob (1654-1705) and Johann
(1667-1748). Jakob and Johann were pioneers
of Leibniz's calculus. Jakob used calculus to
study the forms of many curves arising in
practical situations, and studied
mathematical probability (Ars conjectandi
1713); Bernoulli numbers are named after him.
Johann developed exponential calculus and
contributed to many areas of applied
mathematics, including the problem of a
particle moving in a gravitational field. His
son, Daniel (1700-82) worked on calculus and
probability, and in physics proposed
Bernoulli's principle, which states that the
pressure of a moving fluid decreases the
faster it flows (which explains the origin of
lift on the aerofoil of an aircraft's wing).
This and other work on hydrodynamics was
published in Hydrodynamica 1738.
