Archimedes was an ancient Greek mathematician, physicist, engineer, inventor, and astronomer. He is widely considered one of the greatest mathematicians of all time. His contributions to mathematics include the formulation of the principles of leverage, buoyancy, and the calculation of areas and volumes of various geometric shapes using the method of exhaustion, an early form of integral calculus. Archimedes is also known for the invention of numerous mechanical devices, including the Archimedes screw, a device for raising water. Learn more about Archimedes

## Pythagoras (c. 570 – c. 495 BCE)

Pythagoras was an ancient Greek philosopher and mathematician best known for the Pythagorean theorem, which relates the lengths of the sides of a right triangle. He founded the Pythagorean school of thought, which emphasized the study of mathematics as a means to understand the universe. The Pythagoreans believed that numbers and their relationships were the essence of all things. Pythagoras' work laid the foundations for the study of mathematics as a distinct scientific discipline and influenced subsequent mathematical thinking. Learn more about Pythagoras

## Euclid (c. 300 BCE)

Euclid, often referred to as the "Father of Geometry," was a Greek mathematician whose work "Elements" is one of the most influential books in the history of mathematics. "Elements" is a comprehensive compilation of the knowledge of geometry up to Euclid's time, organized into a coherent framework based on axioms and logical deductions. This work laid the groundwork for the study of geometry for centuries and remains a cornerstone in the field. Euclid's systematic approach and rigorous proofs have profoundly shaped the way mathematics is taught and understood. Learn more about Euclid

He is best known for his work on the stability of the solar system, the Laplace transform, and the theory of probability. His five-volume work, "Mécanique Céleste" (Celestial Mechanics), translated the geometric study of classical mechanics to one based on calculus, thus laying the groundwork for much of modern physical theory.

## Joseph Fourier (1768 – 1830)

Joseph Fourier was a French mathematician and physicist who is most famous for initiating the study of Fourier series and their applications to problems of heat transfer and vibrations. His seminal work, "Théorie analytique de la chaleur" (The Analytical Theory of Heat), introduced the concept that heat diffusion can be analyzed by decomposing the heat equation into sinusoidal components, a technique now known as Fourier analysis. This approach has become fundamental in many areas of science and engineering.

## Srinivasa Ramanujan (1887 – 1920)

Srinivasa Ramanujan was an Indian mathematician who made extraordinary contributions to mathematical analysis, number theory, infinite series, and continued fractions. Despite having little formal training in pure mathematics, his work contains some of the most profound results in the field. Ramanujan's notebooks, filled with thousands of results, many of which were previously unknown, have inspired a vast amount of subsequent research. His collaboration with G. H. Hardy is particularly notable and highlighted the importance of intuition in mathematical discovery.

## David Hilbert (1862 – 1943)

David Hilbert was a German mathematician recognized for his foundational contributions to various areas of mathematics, including invariant theory, algebraic number theory, the foundations of geometry, and functional analysis.
