Archimedes Discovers Principle of Buoyancy
Archimedes formulated the principle explaining why objects float or sink.
Around 250 BCE, the Greek mathematician and inventor Archimedes discovered the principle of buoyancy, stating that an object submerged in fluid experiences an upward force equal to the weight of the displaced fluid. This discovery, famously linked to his "Eureka!" moment, laid foundational concepts in physics and engineering.
