Archimedes' Principle
Archimedes discovered how to find the volume of an irregularly shaped object by submerging it in a liquid and measuring the displacement of the fluid. This later led him to conclude the idea of buoyancy. Archimedes wanted to calculate this value for any object. Archimedes would derive a ratio relationship between the density of the object over the density of the fluid he submerged the object in which is proportional to the weight of the object over the weight of the displaced fluid. This was his way of modeling the buoyant force on an object that was either fully or partially submerged in a known fluid. For example, if you drop a paper boat in a lake, the boat floats because the weight of the water displaced by the paper boat is greater than the weight of the portion of paper causing the displacement (buoyancy is keeping the boat afloat i.e. buoyant force). This law of physics (Archimedes’ principle) is the foundation of fluid mechanics.
