Daniel Bernoulli
1700 – 1782
Gave fluid dynamics its founding pressure–velocity relation.
One of the mathematical Bernoulli dynasty, Daniel published Hydrodynamica in 1738, giving fluid flow its founding relation between pressure and velocity. It is the principle behind the Venturi, the pitot tube, and every airfoil.
He worked amid a famous rivalry with his own father Johann, who competed with and reportedly plagiarized him. The fluids and airflow calculators here rest on the pressure-velocity trade he was first to write down.
