diego The Historic Formulation
Navier used molecules to map the friction's force, Then Stokes refined the math to plot the fluid's course.
diego Leonhard Euler wrote fluid equations in 1757, but they only worked for frictionless fluids.
diego George Gabriel Stokes refined the equations in 1845 by mathematically defining fluid friction.
Fun Fact
Pitch drop: The world's longest-running lab experiment, started in 1927, proves pitch is a fluid with high viscosity.
Glossary
viscosity (noun)
The state of being thick, sticky, and semifluid in consistency, due to internal friction. Claude-Louis Navier first mathematically incorporated this internal resistance into equations of fluid motion in 1822.
