LES espaces de Hilbert et les opérateurs compacts

Les vidéocours de MATHÉMATIQUES LICENCE portent sur les CALCUL DIFFÉRENTIEL ET CALCUL INTÉGRAL. Calcul différentiel et calcul intégral sont deux sous-ensembles fondamentaux du cours de mathématiques du second cycle. Ce vidéocours propose une série de “zooms” transversaux qui permettent aux étudiants de faire une synthèse de leurs connaissances et de vérifier qu’ils ont acquis les concepts fondamentaux.

Emilio Segre Distinguished Lecture by Andrew Lange: How Did the Universe Begin?

There is strong evidence that the entire Universe sprang from sub-atomic dimensions 13.7 billion years ago in a violent event known as Inflation, but we understand almost nothing of what would have caused this to happen. Scientists around the world are now racing to find important clues in the Cosmic Microwave Background, the faint relic of the primeval fireball that filled the early Universe.

The buzz about pesticides

Bees, the most important pollinators of our crops, are in trouble. All over the world, their populations are decreasing and scientists want to know why. In this video, Nigel Raine and Richard Gill introduce us to the bumblebees they study at Royal Holloway near London. Their experiments show that two commonly used pesticides affect foraging behaviour and brood development, making bumblebee colonies more likely to fail.
