Mathematics has been shaped by brilliant minds across centuries, from ancient times to the modern era. These mathematicians revolutionised fields such as geometry, algebra, calculus, and number theory, laying the groundwork for countless scientific and technological advancements.
Pythagoras (c. 570–495 BCE)
Pythagoras is one of the earliest known mathematicians and is best known for the Pythagorean theorem, which describes the relationship between the sides of a right triangle. He founded a philosophical and religious movement known as Pythagoreanism, which emphasised the role of numbers in understanding the universe. Pythagoras contributed to the study of number theory and developed concepts related to proportions and ratios. His influence extended beyond mathematics into areas such as music theory and philosophy. The idea that numbers underpin the structure of reality remains a central concept in mathematical physics. Pythagoras’s work influenced later thinkers, including Plato and Aristotle, shaping the development of Western philosophy.
Euclid (c. 300 BCE)
Known as the father of geometry, Euclid authored the influential mathematical treatise Elements, which served as a textbook for teaching geometry for centuries. His work laid the foundation for Euclidean geometry, a system of axioms and theorems that is still taught in schools today. Euclid’s logical approach influenced the development of the axiomatic method, which remains a cornerstone of modern mathematics. His work on prime numbers and the fundamental theorem of arithmetic has had a lasting impact on number theory. Euclid’s influence extended into fields such as physics and astronomy. His work was preserved and transmitted through the Islamic Golden Age and later influenced European thinkers during the Renaissance.

Grigori Perelman is a Russian mathematician who solved the Poincaré conjecture, one of the seven Millennium Prize Problems posed by the Clay Mathematics Institute. The conjecture, first proposed by Henri Poincaré in 1904, is a fundamental problem in topology. Perelman’s proof, based on Ricci flow, built on the work of Richard S. Hamilton and introduced groundbreaking techniques in geometric analysis. His work provided a deeper understanding of manifolds and contributed to the classification of three-dimensional spaces. Despite being awarded the Fields Medal and the Millennium Prize, Perelman famously declined both awards, citing dissatisfaction with the mathematical community. His work continues to inspire research in differential geometry, Riemannian geometry, and mathematical physics.
