Pythagoras

28/08/2026

🗓️

🌱Circa 570 BC – Samos, Greece.

🍂Circa 495 BC – Metaponto, Italy.

🌟 Main Contribution

Pythagoras established the famous theorem on right triangles and founded a school linking mathematics, music, and astronomy as fundamental principles of the universe

“All is number”

🧐 Did you know?

Pythagoras governed his mystical school under a set of rigorous and extravagant ascetic rules that astonished the Greek poleis of the era. Convinced of the transmigration of souls, he strictly forbade his disciples from consuming animal meat and, strikingly, from physical contact with or consumption of fava beans due to their sacred symbology. Legend recounts that the mathematical philosopher discovered the consonance of musical tones when he stopped in front of a blacksmith’s shop in Crotone and heard the hammers striking the anvil, observing analytically that harmonic sounds were produced by hammers whose weights held simple fractional relationships.

🏅 Awards and Honors

Pythagoras founded the Pythagorean school, one of the most influential philosophical and scientific institutions of antiquity. His legacy has endured for more than two millennia.

📚 Their name in science

➤ Pythagorean theorem

Fundamental relationship between the sides of a right triangle.

➤ Pythagorean comma

Small interval arising in musical tuning systems based on mathematical ratios.

❓ Who was Pythagoras?

Pythagoras was a Greek philosopher and mathematician, universally recognized as one of the most influential thinkers of ancient history for establishing the foundations of arithmetic geometry and rational philosophy. Born on the island of Samos and having traveled extensively through Egypt and Babylonia to absorb Eastern knowledge, he founded the celebrated Pythagorean school in Crotone, a mystical and scientific brotherhood of absolute secrecy. He possessed a mind imbued with a reverent respect for numerical proportions, convinced that the intimate reality of the universe was composed of pure mathematical essences. Pythagoras did not view the cosmos as an arbitrary chaos of matter, but as a perfect geometric structure regulated by harmonic numerical relationships.

🌍 The world in their time

Before the 6th century BC, geometry and mathematics consisted of a collection of practical rules applied to land surveying and architecture, lacking an abstract deductive method seeking to prove the universal truth of theorems independently of material utility or rudimentary empirical calculation.

🔬 Scientific legacy

Pythagoras revolutionized sciences by formulating and popularizing the famous Pythagorean Theorem, establishing geometrically that in any right-angled triangle, the square of the hypotenuse is equal to the sum of the squares of the other two sides ($a^2 + b^2 = c^2$). In musical acoustics, he pioneered discoveries showing that musical intervals correspond to simple, whole numerical proportions, demonstrating mathematically through monochord experiments that a note’s pitch depends on the vibrating string’s length. In astronomy, he early on proposed the sphericity of the Earth and divided the planet into stable climatic zones.

👣 Footprint in today's world

The legacy of Pythagoras forms the conceptual foundation of contemporary plane geometry, trigonometric analysis, structural architecture, and music theory. His fundamental geometric theorem is the basic analytical tool used daily in civil engineering, three-dimensional modeling software design, land surveying, satellite GPS navigation, and elementary scientific education across the planet.

🏃‍♂️ The relay race

📥 Taking the baton

The monumental deductive breakthroughs of Pythagoras built firmly upon arithmetic calculations developed by Babylonian scribes, Egyptian land measurements, and initial philosophical teachings by Thales of Miletus.

📤 Passing the baton

The analytical unification between number and space achieved by Pythagoras transformed mathematics into the backbone of natural philosophy, serving as an indispensable intellectual pillar for Plato’s dialogues and Euclid’s subsequent axiomatic geometry. His acoustic and geometric discoveries laid the doctrinal foundations allowing Johannes Kepler to formulate his celestial mechanical harmony of the world at the birth of the 17th-century Scientific Revolution.
