Code-Breakers: Bletchley Park’s Lost Heroes

Documentary revealing the secret story of how two men hacked into Hitler's personal super-code machine

Documentary that reveals the secret story behind one of the greatest intellectual feats of World War II, a feat that gave birth to the digital age. In 1943, a 24-year-old maths student and a GPO engineer combined to hack into Hitler’s personal super-code machine – not Enigma but an even tougher system, which he called his ‘secrets writer’.

Their break turned the Battle of Kursk, powered the D-day landings and orchestrated the end of the conflict in Europe. … Ler mais

Trillion Dollar Bet

The film tells the fascinating story of the invention of the Black-Scholes Formula, a mathematical Holy Grail that forever altered the world of finance and earned its creators the 1997 Nobel Prize in Economics

In 1973, three brilliant economists, Fischer Black, Myron Scholes, and Robert Merton, discovered a mathematical Holy Grail that revolutionized modern finance. The elegant formula they unleashed upon the world was sparse and deceptively simple, yet it led to the creation of a multi-trillion dollar industry. Their bold ideas earned Scholes and Merton a Nobel Prize (Black died before the prize was awarded) and attracted the elite of Wall Street.

In 1993, Scholes and Merton joined forces … Ler mais

Horizon: The Midas Formula

A beautiful mathematical formula that changed the world

This is the extraordinary story of a beautiful mathematical formula that changed the world, the financial markets, and indeed capitalism itself. It could do the unthinkable – it took the risk out of playing the money-markets. To its inventors it brought the Nobel Prize for economics. To those who used it, it brought great wealth. But this glittering tale would end in tragedy.

The Black Scholes formula was invented 25 years ago, by three young mathematicians. They had been … Ler mais

Évariste Galois (Alexandre Astruc, 1965)

Les dernières heures du génial mathématicien mort en duel à l’âge de 21 ans

C’est un court-métrage de 25 minutes.

Rarement les maths ont été intégrées à un film avec un tel respect de la discipline. Une poignée de dialogues ne seront intelligibles qu’aux anciens élèves de maths-spé ayant bonne mémoire. Mais cela n’empêchera pas le vulgum pecus de comprendre dans quelle mesure les théories de Galois ont été méprisées par l’académie de son temps. Astruc oppose le génie fulgurant de Galois à l’esprit étriqué des polytechniciens. Cette opposition est présentée sans manichéisme outrancier, … Ler mais

Secrets and lies: The hidden power of maths

Mathematician Dr Hannah Fry presents the 2019 CHRISTMAS LECTURES

We think our lives unfold thanks to a mix of luck and our own personal choices. But that’s not quite true. An unseen layer of mathematics governs every aspect of our world. 

Life’s most astonishing miracles can be understood with probability. Big data dictates many of the hot new fashions we follow. Even our choices on Netflix, or our choice of who we marry, is secretly influenced by computer algorithms. 

In a series of lectures packed with mind-boggling demos and … Ler mais

The Royal Institution: Talks all about mathematics

Full length talks from the world’s leading scientists and writers

The Royal Institution was founded to introduce new technologies and teach science to the general public through lectures and demonstrations. Humphry Davy, one of the first Professors, established scientific research as a crucial part of the Ri’s identity, something never envisaged by the founders of the institution.

Over the last two centuries our building and labs have been home to famous scientists, such as Michael Faraday, who made discoveries here which have helped shape the modern world.… Ler mais

To Infinity and Beyond

Horizon examines the story of infinity – older than time, bigger than the universe and stranger than fiction

By our third year, most of us will have learned to count. Once we know how, it seems as if there would be nothing to stop us counting forever. But, while infinity might seem like an perfectly innocent idea, keep counting and you enter a paradoxical world where nothing is as it seems.

Mathematicians have discovered there are infinitely many infinities, each one infinitely bigger than the last. And if the universe goes on forever, the consequences are even more … Ler mais

Nature’s Mathematics

Patterns, shapes, and colours

Nature follows a number of intricate and subtle mathematical rules to produce the patterns, shapes, and colours that we find so mesmerizing.

Episode 1

Wherever we find patterns and symmetry in nature, we also find that nature conforms to certain rules. Rules that combine elegance with efficiency. Rules that shape trees and river estuaries alike, and that continue to baffle scientists by their often unfathomable ubiquity.
