1. Archimedes formulated the principle of buoyancy, also known as Archimedes' principle, which states that a body submerged in fluid experiences an upward force equal to the weight of the fluid displaced.
2. He invented several war machines, including the Archimedes Claw, designed to protect Syracuse from Roman invasion during the Siege of Syracuse.
3. Archimedes made significant contributions to geometry, including methods for calculating areas and volumes of shapes like spheres and cylinders.
4. He is credited with approximating the value of pi more accurately than anyone before him, using inscribed and circumscribed polygons.
5. His work influenced later scientists and mathematicians, including Galileo and Newton, solidifying his legacy as one of the greatest thinkers of antiquity.
