Archimedes, the renowned ancient Greek mathematician, made numerous groundbreaking contributions to the field of mathematics and science. His work in geometry, in particular, revolutionized the way we understand and calculate various geometric properties.
Here are some of Archimedes’ key contributions to geometry:
Calculating the Area of a Circle
One of Archimedes’ most famous achievements was his method for calculating the area of a circle. He realized that by inscribing polygons inside and outside the circle, he could approximate its area. As the number of sides on the polygons increased, the accuracy of the approximation improved.
Archimedes eventually determined that the area of a circle is equal to the product of its radius squared and the constant π (pi). This discovery laid the foundation for modern calculus and the development of integral calculus in particular.
Determining the Volume of a Sphere
Archimedes also made significant contributions to calculating the volume of a sphere. He developed a method known as the “method of exhaustion” to find an approximation for the volume of a sphere. By inscribing and circumscribing cones and cylinders around the sphere and comparing their volumes, Archimedes was able to determine that the volume of a sphere is two-thirds the volume of a circumscribing cylinder.
This groundbreaking insight laid the groundwork for future advancements in solid geometry and calculus.
Archimedes’ Innovations in Trigonometry
In addition to his achievements in circle and sphere calculations, Archimedes also made significant contributions to trigonometry. He developed formulas and techniques for approximating the values of trigonometric functions, such as sine, cosine, and tangent.
These calculations were instrumental in solving complex geometric problems and paved the way for further advancements in trigonometry.
Archimedes’ contributions to geometry have had a lasting impact on the field of mathematics. His methods and formulas continue to be studied and utilized by mathematicians and scientists today.

Archimedes’ Discoveries in Physics and Engineering
Law of the Lever
Archimedes made significant breakthroughs in the field of physics, particularly his discovery of the Law of the Lever. This principle states that with the right balance of force and distance, a small force can move a larger object.
Archimedes famously said, “Give me a lever long enough and a fulcrum on which to place it, and I shall move the world.” This law revolutionized the way people understood the concept of leverage and greatly influenced the development of engineering and machinery.
Today, the Law of the Lever is still widely used in various applications, from construction to manufacturing.
Law of Buoyancy and Displacement
Another significant contribution by Archimedes was his understanding of the Law of Buoyancy and Displacement. He discovered that an object submerged in a fluid experiences an upward force equal to the weight of the fluid it displaces.
This principle, known as Archimedes’ Principle, laid the foundation for our understanding of buoyancy and its applications in shipbuilding and hydrodynamics. Archimedes’ insights into buoyancy have played a crucial role in the development of modern naval architecture and have contributed to the construction of more stable and efficient boats and ships.
Inventing Defensive War Machines
Archimedes was not only a brilliant scientist but also a practical engineer. During the Roman siege of Syracuse, he designed and built various defensive war machines that played a decisive role in defending the city.
One of his most famous inventions was the “Claw of Archimedes,” a giant grappling hook mechanism that could lift enemy ships out of the water and then drop them, causing them to capsize. Archimedes’ inventions were so effective that they delayed the Roman conquest of Syracuse for several years.
These innovations showcased his ingenuity and engineering prowess, leaving a lasting impact on the field of military technology.
Archimedes’ discoveries in physics and engineering have had a profound impact on the scientific community and continue to influence modern-day advancements. His laws of leverage and buoyancy have shaped the way we approach engineering challenges, while his ingenious war machines demonstrated the power of innovation in times of conflict.
