Archimedes was an ancient Greek mathematician, physicist, and inventor. He made important contributions to mathematics, physics, and engineering. Archimedes formulated principles like Archimedes’ Principle and the law of the lever.
He invented devices such as the Archimedes’ screw for lifting water. He also made advancements in calculating pi and worked on geometric shapes and solids.
Archimedes’ work was highly regarded, but he met a tragic end during the Roman siege of Syracuse. His writings were later rediscovered, and he is celebrated for his brilliance and contributions.
Accomplishments of Archimedes
1. Archimedes’ Principle
Archimedes formulated the principle of buoyancy, which states that when an object is immersed in a fluid, it experiences an upward buoyant force equal to the weight of the fluid it displaces.

This principle has far-reaching applications, such as explaining why objects float or sink in fluids. Archimedes’ Principle is fundamental in shipbuilding, understanding the behavior of submarines, and designing various flotation devices.
2. Archimedes’ Screw
Archimedes is credited with inventing the Archimedes’ screw, a simple yet effective device for lifting water. It consists of a screw-shaped surface wound around a cylinder. When the screw is rotated, it lifts water from a lower level to a higher level.
This invention has been used for irrigation systems, drainage, and even in modern applications like pumping water in wastewater treatment plants.
3. Calculation of Pi (π)
Archimedes made significant contributions to the approximation of the value of pi (π). He devised a method to calculate pi using polygons inscribed within and circumscribed around a circle. By increasing the number of sides of these polygons, Archimedes obtained increasingly accurate approximations of pi.
His work laid the foundation for subsequent mathematicians to develop more sophisticated algorithms and formulas to calculate pi, a fundamental mathematical constant used in countless scientific and engineering applications.
4. Archimedes’ Claw
During the Siege of Syracuse, Archimedes invented a defensive weapon known as the “Archimedes’ Claw” or “Iron Hand.” This device was designed to protect the city’s harbor. It consisted of a large crane-like mechanism with a grappling hook attached to it.
When enemy ships approached, the Claw would extend over the water and grip the vessels with its hook. Then, the crane would lift the ships out of the water, destabilizing and potentially capsizing them.
The Archimedes’ Claw was an innovative and effective naval defense mechanism that demonstrated Archimedes’ engineering prowess and strategic thinking.
5. Law of the Lever
Archimedes discovered and formulated the principle known as the law of the lever. This principle states that a lever will be in balance when the product of the weight on one side and its distance from the fulcrum is equal to the product of the weight on the other side and its distance from the fulcrum.
In simple terms, it means that the longer arm of a lever can balance a heavier weight on the shorter arm, provided the distance from the fulcrum is adjusted accordingly.
The law of the lever is a fundamental principle in mechanics and has widespread applications in engineering, from simple tools to complex machinery.
6. Method of Exhaustion
Archimedes developed a mathematical technique called the method of exhaustion, which was a precursor to the concept of integration in calculus. This method allowed him to calculate the areas and volumes of irregular shapes and curves.
The method involved approximating the shape with a series of smaller, simpler shapes whose areas or volumes were known.
By progressively refining these approximations, Archimedes was able to obtain increasingly accurate calculations. The method of exhaustion was a groundbreaking approach that laid the groundwork for the later development of integral calculus by mathematicians like Isaac Newton and Gottfried Wilhelm Leibniz. It provided a powerful tool for solving problems involving areas, volumes, and curves.
7. Determination of the Center of Gravity
Archimedes developed methods to determine the center of gravity of various objects. The center of gravity is the point at which an object’s weight is evenly balanced in all directions. Archimedes’ work on the center of gravity allowed him to understand the principles of balance and stability.
By determining the center of gravity of different objects, he could make accurate predictions about their behavior and design structures that were stable and resistant to tipping or toppling. Archimedes’ understanding of the center of gravity was crucial in fields like architecture, engineering, and the construction of stable structures.
8. Archimedean Solids
Archimedes discovered and studied a set of 13 polyhedra, known as the Archimedean solids. These are convex polyhedra with identical vertices and identical faces.
Archimedes examined the properties and characteristics of these solids, including their symmetries and relationships between their faces, edges, and vertices.
His work on the Archimedean solids laid the foundation for the later study of polyhedra and had a significant impact on geometry and crystallography.
Archimedes made substantial contributions to the field of hydrostatics, which is the study of fluids at rest and their behavior under pressure. He formulated principles and developed mathematical equations to understand fluid pressure and the equilibrium of fluids.
Archimedes’ insights into hydrostatics provided a deeper understanding of fluid mechanics and had practical applications in fields such as engineering, shipbuilding, and hydraulic systems.
His work in this area was fundamental in advancing our understanding of the behavior of fluids and laid the groundwork for further advancements in fluid dynamics.
10. Quadrature of the Parabola
Archimedes developed a method for calculating the area enclosed by a parabola and a straight line. This accomplishment was part of his broader work on mathematics and geometry. The quadrature of the parabola refers to finding the exact area of a region bounded by a parabola and a straight line.
Archimedes’ method involved approximating the area using inscribed and circumscribed polygons, similar to his approach for calculating pi. His work on the quadrature of the parabola contributed to the development of integral calculus and played a significant role in the understanding of geometric shapes and their areas.
