This Documentary describes Pythagoras. It was produced by Cromwell Productions in 1996.

Pythagoras (fl. 530 BCE) must have been one of the world’s greatest men, but he wrote nothing, and it is hard to say how much of the doctrine we know as Pythagorean is due to the founder of the society and how much is later development.

It is also hard to say how much of what we are told about the life of Pythagoras is trustworthy; for a … Ler mais

Cubo de Rubik tem solução universal: 20 movimentos

Investigadores britânicos precisaram de super computador da Google para processar cálculos

Encontrar a solução para o cubo de Rubik já deu voltas à cabeça de milhões de pessoas em todo o mundo. Muitas nunca conseguiram completar o jogo criado em 1974 pelo arquiteto húngaro Ernõ Rubik.

Em 1981, o matemático Morwen Thistlethwaite chegou a um algoritmo capaz de resolver qualquer posição do cubo mágico em 52 movimentos. Desde então, o número tem vindo a ser reduzido – a última vez, Ler mais

A Vida Secreta do Caos

O Professor Jim Al-Khalili tenta descobrir um dos grandes mistérios da ciência

A teoria do caos tem um mau nome, evocando imagens de clima imprevisível, falhas económicas e ciência errada. Mas há um lado fascinante e escondido do Caos, que os cientistas só agora começam a entender.

Acontece que a teoria do caos responde a uma pergunta que a humanidade tem feito durante milénios – Como chegámos aqui?

Neste documentário, o Professor Jim Al-Khalili tenta descobrir um dos grandes mistérios da ciência – como é que um universo que começa por ser … Ler mais

Benoit Mandelbrot: Fractais e a arte da rugosidade

O trabalho de Benoit Mandelbrot levou o mundo a uma compreensão mais profunda dos fractais

No TED2010, o matemático Benoit Mandelbrot desenvolve um tema que discutiu primeiramento no TED em 1984 — a complexidade extrema da rugosidade, e o modo como a matemática fractal pode encontrar organização em padrões que parecem desconhecidamente complicados.

Arte & Matemática

Uma viagem com paradas em algumas estações do espaço-tempo, da ciência, beleza, Arte & Matemática

Esta série de 13 programas é uma viagem não linear em barco de duas quilhas: uma é a Arte, a outra a Matemática, interligadas por uma estrutura segura, a Estética.

Em todas as épocas, os homens observam a Natureza e procuraram respostas para as suas perguntas. Alguns chegaram à música, outros desenvolveram as esculturas. A harmonia foi contraposta ao caos. Alguns perceberam a regularidade na natureza, outros se encontraram com o inesperado.

Os programas partem da certeza de que a … Ler mais

La Saga des Nobel

Les Nobel ont cent ans. L’impressionnante liste des lauréats du Prix Nobel montre ce que la pensée scientifique, occidentale d’abord puis mondiale, a produit de plus performant au service de la connaissance. L’histoire de ces éminents savants, tels Einstein, Pierre et Marie Curie, Pavlov, Flemming, etc. c’est l’histoire du XXe siècle. Leur vie croise les grands événements historiques, leurs découvertes y contribuent et en sont parfois à l’origine.

L’ambition de cette série est de montrer qu’avec ces femmes et ces … Ler mais

A Brilliant Madness

The life of the Nobel Prize-winning mathematician and schizophrenic John Nash

A Brilliant Madness is the story of a mathematical genius whose career was cut short by a descent into madness. At the age of 30, John Nash, a stunningly original and famously eccentric MIT mathematician, suddenly began claiming that aliens were communicating with him and that he was a special messenger. Diagnosed with paranoid schizophrenia, Nash spent the next three decades in and out of mental hospitals, all but forgotten.

During that time, a proof he had written at … Ler mais

High Anxieties: The Mathematics of Chaos

Documentary which looks at how developments in mathematics over the past 40 years have completely changed our understanding of the fundamental nature of the world we live in

Documentary which looks at how developments in mathematics over the past 40 years have completely changed our understanding of the fundamental nature of the world we live in.

As we approach tipping points in both the economy and the climate, the film examines the mathematics we have been reluctant to face up to and asks if, even now, we would rather bury our heads in the sand rather than face harsh truths.

The Music of the Primes

Marcus du Sautoy presents the story of those who have tried to capture one of the greatest unsolved problems of mathematics, the pattern of prime numbers

For more than 2000 years, a mathematical riddle has baffled the world’s greatest minds. It’s a problem of such difficulty that it has tormented those mathematicians brave enough to tackle it. Some have given up in despair. Others have been driven mad.

Yet it’s a conundrum that helped Britain to win the Second World War; that was instrumental in the birth of the computer; and that has shed light on the behaviour of atoms, the building blocks of matter itself.… Ler mais

E=mc2: Einstein’s Big Idea

NOVA dramatizes the remarkable story behind this equation

Exactly 100 years ago, Albert Einstein grappled with the implications of his revolutionary special theory of relativity and came to a startling conclusion: mass and energy are one, related by the formula E = mc2. In “Einstein’s Big Idea,” NOVA dramatizes the remarkable story behind this equation.

E = mc2 was just one of several extraordinary breakthroughs that Einstein made in 1905, including the completion of his special theory of relativity, his identification of proof … Ler mais

N is a Number: A Portrait of Paul Erdös

The story of a wandering mathematician obsessed with unsolved problems

I do not know what I may appear to the world; but to myself I seem to have been only like a boy playing on the seashore, and diverting myself in now and then finding a smoother pebble or a prettier shell than ordinary, whilst the great ocean of truth lay undiscovered before me. — Sir Isaac Newton

A man with no home and no job, Paul Erdös was the most prolific mathematician who ever lived. Born in Hungary in … Ler mais

Fractals – Hunting the Hidden Dimension

Mysteriously beautiful fractals are shaking up the world of mathematics and deepening our understanding of nature

You may not know it, but fractals, like the air you breathe, are all around you. Their irregular, repeating shapes are found in cloud formations and tree limbs, in stalks of broccoli and craggy mountain ranges, even in the rhythm of the human heart. In this film, NOVA takes viewers on a fascinating quest with a group of maverick mathematicians determined to decipher the rules that govern fractal geometry.

For centuries, fractal-like irregular shapes were considered beyond the boundaries … Ler mais

The History of the Archimedes Palimpsest

At 2pm on October 29th, 1998, at Christie’s auction house in New York, a very special old book was sold to an anonymous collector for $2,000,000

At 2pm on October 29th, 1998, at Christie’s auction house in New York, a very special old book was sold to an anonymous collector for $2,000,000. This collector deposited the manuscript at The Walters Art Museum in Baltimore in order to conserve it, image it, and study it.

The book is special because it contains seven treatises by the ancient Greek mathematician Archimedes. Two of these treatises, The Stomachion and The Method exist nowhere else in the world. This … Ler mais
