Mariotte and Huygens

Edme Mariotte (1620-1684) and Christian Huygens (1629-1695) are the theorists who brought the velocity-squared law to fluid dynamics. The remarkable thing is that they did not work together on this law, but arrived at the same conclusion.

The velocity-squared law explains why it’s difficult to go a bit faster when you’re already moving very fast. It states that resistance is not linear. Because of this, the rate at which fluid resistance increases, increases more quickly than the speed at which you’re moving. This concept is especially important when designing large vessels.
