From a Greek cult leader who heard the world as - ratios to a wandering Hungarian who slept on his colleagues' couches — the people who - invented the language we count, calculate, and reason in. - Pythagoras → Erdős - 13 slides ### Slide 2: Pythagoras - No. 01 · Antiquity - P Y T H A G O R A S - Samos · Croton - c. 570 – 495 BC - Founded a secretive religious-mathematical brotherhood in southern Italy where members - swore oaths, abstained from beans, and treated number as the substance of reality. - "All is number." The theorem on right triangles bears his name though Babylonian - scribes knew the relation a millennium earlier. - "Discovered" musical ratios — that a string halved sounds an octave higher — - and inferred from it that the cosmos is harmony made audible. ### Slide 3: Euclid - No. 02 · Hellenistic Alexandria - E U C L I D - Alexandria - fl. c. 300 BC - Compiled the Elements — thirteen books that derived plane geometry, - number theory and solid geometry from five postulates and a handful of common notions. - For two thousand years, learning mathematics meant learning Euclid; only the Bible has - been printed in more editions. - Almost nothing survives of Euclid the man. We know him only through the rigour of the - text and a remark to King Ptolemy: "there is no royal road to geometry." ### Slide 4: Archimedes - No. 03 · Syracuse - A R C H I M E D E S - Sicily - c. 287 – 212 BC - Bounded π between 3⅙ and 3⅞, calculated areas with proto-integration, - designed war machines that held off the Roman fleet, and ran naked from his bath - shouting Eureka! after grasping displacement. Killed by a Roman soldier - while drawing circles in the sand — "Do not disturb my diagrams." - "Give me a place to stand and I will move the Earth." — on the lever, - which he was first to analyse mathematically. ### Slide 5: Isaac Newton - No. 04 · Cambridge - N E W T O N - Woolsthorpe · Trinity - 1643 – 1727 - In two plague-haunted years at his mother's farm, the young Newton invented the - calculus, decomposed white light with a prism, and wrote down the inverse-square law - of gravitation. The Principia (1687) explained the planets, the tides, and - the falling apple from a single set of equations. - Also: alchemist, biblical exegete, Master of the Royal Mint who hanged counterfeiters. - "If I have seen further it is by standing on the shoulders of Giants." ### Slide 6: Leonhard Euler - No. 05 · St Petersburg · Berlin - E U L E R - Basel-born - 1707 – 1783 - The most prolific mathematician in history — some 866 publications, occupying 90+ - volumes and still being edited. Founded graph theory (the Bridges of Königsberg), - standardised the notation of e, i, π and Σ, and kept working - after going blind in 1771 by dictating to scribes. - His identity eiπ + 1 = 0 binds five fundamental - constants in nine symbols — routinely voted the most beautiful equation ever written. ### Slide 7: Carl Friedrich Gauss - No. 06 · Göttingen - G A U S S - Brunswick · Göttingen - 1777 – 1855 - Schoolboy prodigy who summed 1 to 100 in seconds. By 24 he had written - Disquisitiones Arithmeticae — the foundation of modern number theory — - and predicted where the lost dwarf planet Ceres would reappear, restoring it to - astronomers via least-squares regression he had quietly invented. - Called Princeps mathematicorum, the Prince of Mathematics. His motto: - pauca sed matura — few, but ripe. ### Slide 8: Bernhard Riemann - No. 07 · The Hypothesis - R I E M A N N - Hanover - 1826 – 1866 - Reinvented geometry by treating space as a curved manifold — the mathematics - Einstein needed half a century later for general relativity. Founded modern complex - analysis. In a single ten-page paper proposed the Riemann Hypothesis, still - the most famous unsolved problem in mathematics. - All non-trivial zeros of the zeta function lie on the line Re(s) = ½. - One million dollars to whoever proves it. He died of tuberculosis at 39. ### Slide 9: Srinivasa Ramanujan - No. 08 · Madras · Cambridge - R A M A N U J A N - Erode · Trinity - 1887 – 1920 - A clerk in colonial Madras, largely self-taught from a single textbook, who filled - notebooks with thousands of identities for partitions, modular forms and infinite - series — many discovered, he said, in dreams from the goddess Namagiri. G. H. Hardy - brought him to Cambridge in 1914. - Visiting his sickbed, Hardy mentioned his taxi was 1729 — "a rather dull number." - "No," said Ramanujan, "it is the smallest expressible as the sum of two cubes - in two different ways." Dead at 32. ### Slide 10: Emmy Noether - No. 09 · Erlangen · Bryn Mawr - N O E T H E R - Erlangen - 1882 – 1935 - The mother of modern abstract algebra. Reformulated rings, ideals and fields in the - language still used today. Her 1918 theorem — every continuous symmetry of the - laws of physics yields a conservation law — is the silent hinge of all - modern theoretical physics. - Forbidden to lecture in Göttingen as a woman, she taught for years under Hilbert's - name. Expelled by the Nazis in 1933, she died of an ovarian-cyst operation at Bryn Mawr - two years later. ### Slide 11: Alan Turing - No. 10 · Bletchley Park - T U R I N G - King's College - 1912 – 1954 - At 23 defined what computation is — the universal Turing machine — - and proved the halting problem unsolvable. At Bletchley Park led the team that broke - the German Enigma cipher, shortening WWII by an estimated two years. Founded - theoretical computer science and, with the Imitation Game, AI. - Convicted of "gross indecency" in 1952 for being gay, sentenced to chemical - castration, and dead by cyanide at 41. Britain pardoned him in 2013. ### Slide 12: Paul Erdős - No. 11 · Everywhere - E R D Ő S - Budapest · the world - 1913 – 1996 - Hungarian number theorist who renounced home, possessions and most meals to live out - of a suitcase, criss-crossing five continents to co-author papers with anyone willing. - Some 1,500 papers with 500+ collaborators — more than any mathematician in history. - Your Erdős number is the shortest co-authorship distance to him. - Einstein's was 2; Chomsky's, 4. Coffee was, he said, the device that turns - mathematicians into theorems. ### Slide 13: Further reading& viewing - Coda - Two short documentaries that bring two of these lives to the screen — - and a starting bibliography for the rest. - Ramanujan on YouTube - The man who knew infinity — lectures, films, archive footage. - youtube · search - Noether's Theorem on YouTube - Symmetry and conservation, explained in plain language. - youtube · search - E.
