Darwin's mother and the miniature: with Randal Keynes
Charles Darwin's mother Susannah Wedgwood died when he was just eight, and he could never remember her face - until he discovered a long-hidden portrait of her as a young woman. Hear Darwin's great-great-grandson Randal Keynes explain why finally seeing this miniature of his mother (on display at the Fitzwilliam Museum) was so significant for the great naturalist, and why portraits of loved ones were so important to both the Wedgwood and Darwin families.
JFK50 A Career Born Out of the Inaugural — Robert Stavins
Robert Stavins, business and government professor at Harvard Kennedy School, says he owes his entire career path — from student to Peace Corps volunteer to environmental protector — to JFK's inaugural speech.
The Arctic Circle Polar Bears
This video has no words or facts but is instead a wonderful look into animals of the Arctic Circle in their natural habitats. The most viewed animal is the polar bear including a mother and her 2 cubs. Some other animals briefly seen include the Arctic Fox, two different types of birds, and reindeer. This video would be fun for pre-learners to see these animals outside of a zoo setting, but older learners could follow the lesson underneath the video to answer the following questions:
The Last Moments of the Columbia Astronauts
This ten minute video is the only video recovered after Columbia disintegrated during re-entry. It depicts the crew during their final preparations, before landing. The tape ends four minutes before the first failure. The rest of the video was destroyed. The use of this video may be limited in use for most classrooms due to its quality and subject matter. However, it does portray what happens on this flight and the risks that humans face when seeking new frontiers.
Antibody-protein interactions: benchmark datasets and prediction tools evaluation
Background
The ability to predict antibody binding sites (aka antigenic determinants or B-cell epitopes) for a given protein is a precursor to new vaccine design and diagnostics. Among the various methods of B-cell epitope identification X-ray crystallography is one of the most reliable methods. Using these experimental data computational methods exist for B-cell epitope prediction. As the number of structures of antibody-protein complexes grows, further interest in prediction methods using 3D s

Expériences personnelles dans l’enseignement de l’informatique et du monde numérique (video)
L'informatique est partout, c'est devenu banal de le dire, mais qu'entend-on vraiment par là ? Comprend-on bien que le numérique, aujourd'hui, loin de se cantonner aux ordinateurs, est bien plus répandu dans les objets technologiques les plus divers, des téléphones aux avions ? Quelles en sont les implications, les qualités mais aussi les inconvénients, à commencer par les bugs ? En accord avec la devise du Collège de France, « enseigner la recherche en train de se faire », Gérar
Les algorithmes de classement utilisés dans les moteurs de recherche (video)
Dans cet exposé Michel Habib nous explique comment fonctionne google, quels sont les mécanismes algorithmiques qui permettent de calculer le "ranking" d'une page, et comment fonctionne l'indexation de cet océan de page. Ce sont les mécanismes algorithmiques qui sont mis en lumière ici, ce qui permet de les démystifier. Quelques belles anecdotes sur le web et quelques jolis exercices sont proposés en illustration.

Adult butterfly anatomy
The butterfly can fly around using its wings and sees where it is going through its eyes. The spiracles allow the butterfly to breathe and the legs are what it uses to walk or crawl around on. The antennae help the butterfly know where it is going. The proboscis is what the butterfly uses to drink nectar from flowers.

George Inness in Italy
February 19, 2011 - May 15, 2011: A canonical figure in American painting, George Inness (1825–1894) is widely admired as the pioneer of the evocative aesthetic
known as Tonalism, which is distinguished by soft focus and diaphanous layers of paint. This is the first exhibition to examine the artist’s two Italian sojourns (1851–52 and 1870–74) and their formative impact on his work. Italy—its art and its landscape—offered Inness a font of inspiration as he developed his own uniq
