Richard Feynman – No Ordinary Genius

BBC Horizon explores the life and times of Richard Feynman – through the eyes of the man himself and his family

BBC Horizon explores the life and times of Richard Feynman – through the eyes of the man himself and his family.

Many aspects of this documentary have been used before in Horizon and Nova episodes, the Messenger series is also referenced.

Presented with his charismatic, passion and zest for life and knowledge, the phrase ‘the pleasure of finding things out’ always sums Richard up and is what is great about science.

Richard Feynman: The Pleasure Of Finding Things Out

Professor Richard Feynman of Caltech talks about his life and career

Richard Feynman was one of the most brilliant theoretical physicists and original thinkers of the 20th century. He rebuilt the theory of quantum electrodynamics, and it was for this work that he won the Nobel Prize in 1965.

In 1981, he gave Horizon a candid interview, talking about many things close to his heart.

Richard Feynman: Fun to Imagine

Using physics to explain how the world works

Richard Feynman (1918-88) was one of the most remarkable and gifted theoretical physicists of any generation. He was also known as the ‘Great Explainer’ because of his passion for helping non-scientists to imagine something of the beauty and order of the universe as he saw it.

In this series, Feynman looks at the mysterious forces that make ordinary things happen and, in doing so, answers questions about why rubber bands are stretchy, why tennis balls can’t bounce for ever and … Ler mais

Pythagoras

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

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

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
