Gravity and Me: The Force that Shapes our Lives

Professor Jim Al-Khalili investigates the amazing science of gravity. As well sculpting our universe, gravity also affects our weight, height and even the rate at which we age.

Physics professor Jim Al-Khalili investigates the amazing science of gravity. A fundamental force of nature, gravity shapes our entire universe, sculpting galaxies and warping space and time. But gravity’s strange powers, discovered by Albert Einstein, also affect our daily lives in the most unexpected ways. As Jim tells the story of gravity, it challenges his own understanding of the nature of reality.

The science of gravity includes the greatest advances in physics, and Jim recreates groundbreaking experiments in gravity … Ler mais

The Art of the Impossible: MC Escher and Me

Sir Roger Penrose takes a personal journey through artist MC Escher's work

World-leading cosmologist Professor Sir Roger Penrose is more than just a fan of MC Escher‘s mind-bending art. During the course of a long creative collaboration, the British mathematician and the Dutch artist exchanged ideas and inspirations. Some of Escher’s most iconic images have their origin in Penrose’s mathematical sketches – while the artist’s work has served as a starting point for the professor’s own explorations of new scientific ideas. To coincide with the first ever Escher retrospective in the … Ler mais

Escher’s Infinite Perspective

An inquiry around the mystery behind the missing hole in M. C. Escher "Print Gallery"

M. C. Escher is among the most intriguing of artists. In 1956 he challenged the laws of perspective with his graphic Print Gallery, and found himself trapped by an impossible barrier. His uncompleted master-piece quickly became the most puzzling enigma of modern art, for both artists and scientists.

Half a century later, mathematician Hendrik Lenstra took everyone by surprise by drawing a fantastic bridge between the intuition of the artist and his own, and completed Escher’s work mathematically.

Magic Numbers: Hannah Fry’s Mysterious World of Maths

Documentary series in which Dr Hannah Fry explores the mystery of maths. Is it invented like a language or is it discovered and part of the fabric of the universe?

In this new series, mathematician Dr Hannah Fry explores the mystery of maths. It underpins so much of our modern world that it’s hard to imagine life without its technological advances, but where exactly does maths come from? Is it invented like a language or is it something discovered and part of the fabric of the universe?

It’s a question that some of the most eminent mathematical minds have been wrestling with. Dr Eleanor Knox from King’s College London believes … Ler mais

Chandra – The Journey of a Star

Um filme documentário de Giuseppe Mussardo e Enrico Agapito

Na manhã do 1.º de agosto de 1930, em Bombaim, o cais da P&OLinhas Peninsular e Oriental – estava totalmente lotado e havia a confusão habitual de qualquer partida: carregadores transportavam bagagens e grandes caixas, os oficiais estavam ocupados dando as últimas ordens e marinheiros subiam e desciam dos conveses entre cordas e ovéns. Andavam por ali estrangeiros olhando com admiração o Portal da Índia, considerado a quinta-essência da Índia colonial, um monumento erguido pela Inglaterra … Ler mais

Conhecimento Perigoso

Neste documentário único, David Malone observa quatro brilhantes homens da ciência - Georg Cantor, Ludwig Boltzmann, Kurt Gödel e Alan Turing - cujo génio nos afetou profundamente, mas que tragicamente os enlouqueceu e acabou levando a cometer suicídio

Este documentário, dividido em duas partes de 45 minutos, explora a modo de homenagem a vida de quatro cientistas: Cantor, Gödel, Turing e Boltzmann. As vidas destes três matemáticos e um físico tiveram algumas coisas em comum: eles exploraram terrenos perigosos do conhecimento, à frente do seu tempo, o que os levou a sofrer a rejeição da comunidade científica. E todos eles tiveram um final trágico no crepúsculo das suas vidas. Apesar disso, o seu trabalho recebeu com o passar … Ler mais

Ludwig Boltzmann – O génio da desordem

Um filme documentário de Enrico Agapito, Giuseppe Mussardo e Petra Scudo

O físico do século XIX Ludwig Boltzmann provocou controvérsia ao propor que os cientistas pudessem fazer estimativas inteligentes sobre o comportamento dos átomos, que, embora se movessem aleatoriamente, poderiam ser descritos por certas generalizações probabilísticas. A sua sugestão de explicar a termodinâmica usando métodos estatísticos foi contra a tendência de longa data de assumir leis fixas absolutas. Estas foram mudanças profundas e perturbadoras.

O filme é sobre a envolvente história da ciência e da luta pessoal de Ludwig Boltzmann, confrontada … Ler mais
