PATRICE JEENER – Le graveur de mathématiques

Les mathématiques, si abstraites parfois imaginaires, se dessinent et se gravent sous nos yeux et sous les doigts de Patrice Jeener, artiste graveur

La Motte-Chalancon, Drôme provençale, hiver 2016.
Une silhouette enveloppée d’une cape noire arpente les rues étroites et biscornues du village médiéval. Comme sorti tout droit d’un film gothique, Patrice Jeener nous accompagne dans sa maison en marmonnant des formules mathématiques et il nous présente son travail : des centaines de gravures qui représentent des graphiques, des concepts et des objets mathématiques.

Savez-vous à quoi ressemble un hyperboloïde à deux nappes ? Ou un hypercube à 7 dimensions ? Patrice … Ler mais

Einstein et la Relativité Générale, une histoire singulière

Cet anniversaire (2015) est l’occasion de rappeler l’importance paradoxale de la théorie dans le monde scientifique

La théorie de la Relativité Générale d’Albert Einstein a révolutionné notre conception de la gravitation, de l’espace et du temps. D’abord encensée, puis oubliée, et redécouverte, l’histoire de cette théorie centenaire a marqué l’histoire scientifique du XXème siècle. Dès sa naissance, surgit un problème mathématique qui aurait pu tuer la théorie dans l’oeuf : la singularité de Schwarzschild.

Accompagné par des grands physiciens relativistes internationaux, le film nous emmène à la découverte de cette théorie au destin singulier. … Ler mais

Lagrange

Un documentaire sur le mathématicien d'exception Joseph-Louis Lagrange

L’Institut Henri Poincaré produit un documentaire exclusif de 32 minutes sur le mathématicien d’exception Joseph-Louis Lagrange, en coproduction avec le CNRS Images et en partenariat avec l’Institut Lagrange de Paris.

Des historiens retracent le parcours européen de Lagrange et montrent comment il est passé d’académicien protégé des puissants à un professeur chargé d’éduquer les nouveaux Citoyens au moment de la Révolution Française. Ils posent la question de l’implication des scientifiques dans la vie politique de l’époque.… Ler mais

Gottfried Wilhelm Leibniz – In search of a universal formula

The documentary portrays the genius Leibniz in his time and repeatedly transports him to the present

November 2016 marked the 300th anniversary of the death of Gottfried Wilhelm Leibniz. He was a philosopher, mathematician, historian, diplomat, lawyer and much more besides. Leibniz ranks as the last universal genius. His discoveries and revolutionization of the number system first made computers, the Internet and social networks at all possible.

A major part of his heritage may be found in Hanover, where Leibniz worked for 40 years as a librarian and counsellor at the court of the duke. … Ler mais

LA DRÔLE DE GUERRE D’ALAN TURING

"La drôle de guerre d'Alan Turing... ou comment les maths ont vaincu Hitler"

Alan Turing est, sans aucun doute, l’un des grands esprits scientifiques du XXème siècle. Peu d’autres ont abordé, avec autant de succès, des domaines aussi variés.

Mathématicien, héros (longtemps oublié) de la Seconde Guerre mondiale, il contribue à la victoire des Alliés en cassant les codes allemands… Pionnier de l’informatique, il écrit quelques uns des premiers programmes informatiques et invente l’idée d’intelligence artificielle. Et pourtant, ce destin exemplaire prend un tour tragique : son homosexualité lui vaudra d’être persécuté par … Ler mais

Bento de Jesus Caraça – Matemático e Cidadão

A vida de Bento de Jesus Caraça, matemático e opositor a Salazar

Quando um regime não estimula e, pelo contrário, desencoraja o direito de um povo à educação e à cultura, todos aqueles que promoverem a educação desse mesmo povo são reprimidos. Foi assim com Bento de Jesus Caraça, expulso da Universidade por Salazar.
Em 1941 cria a famosa “Biblioteca Cosmos“, para edição de livros de divulgação científica e cultural, a qual publicou 114 livros, com uma tiragem global de 793 500 exemplares.

A mecânica de Galileu

A Queda Livre – Galileu Descreve o Movimento
Abordaremos o desenvolvimento de um importante exemplo de investigação básica: o estudo dos corpos em queda livre feito por Galileu Galilei. Embora o problema físico da queda livre seja por si só interessante, o estudo será orientado para a maneira como Galileu, um dos primeiros cientistas modernos, apresentou os seus argumentos. A sua perspetiva do mundo, a sua maneira de pensar, o seu uso da matemática e a sua confiança nos testes experimentais, marcam o estilo da ciência moderna. É por isto que estes aspetos do seu trabalho são tão importantes para nós como os resultados reais da sua investigação. Ler mais

Tails You Win: The Science of Chance

Professor David Spiegelhalter tries to pin down what chance is and how it works in the real world

Smart and witty, jam-packed with augmented-reality graphics and fascinating history, this film, presented by professor David Spiegelhalter, tries to pin down what chance is and how it works in the real world. For once this really is ‘risky’ television.

The film follows in the footsteps of The Joy of Stats, which won the prestigious Grierson Award for Best Science/Natural History programme of 2011. Now the same blend of wit and wisdom, animation, graphics and gleeful nerdery is applied … Ler mais

When the Moors Ruled in Europe

Historian Bettany Hughes looks at the influence of the Moorish invasion of Spain in 711 AD, and the lasting cultural and scientific legacy they created

As part of the Channel 4’s Hidden Civilisation season exploring Islam’s rich and significant contribution to western art and culture, historian Bettany Hughes traces the story of the mysterious and misunderstood Moors, the Islamic society that ruled in Spain for 700 years, but whose legacy was virtually erased from Western history.

In 711 AD, a tribe of newly converted Muslims from North Africa crossed the straits of Gibraltar and invaded Spain. Known as The Moors, they went on to build … Ler mais
