A treatise in two books that founds the science of hydrostatics. From a single postulate about the pressure of a fluid, Archimedes proves that a body lighter than a fluid floats with a submerged part whose weight of fluid equals the body's weight, and that a body immersed in a fluid is pushed up by a force equal to the weight of the fluid displaced, the principle that bears his name. Book two applies the results to the stability of floating segments of paraboloids, a problem relevant to the design of ships' hulls.
