Daniel Bernoulli's Hydrodynamica

January 1, 1738

The second of the Basel Bernoullis published his treatise on fluid motion at Strasbourg, introducing the principle that bears his name: as a fluid's speed increases, its pressure falls. Three centuries later, every airplane wing, every carburetor, every curveball, and every medical IV drip still obeys him without asking. His own father, Johann, published a rival treatise backdated to steal priority, adding domestic bitterness to scientific triumph.
