Festival Pariscience Rendez-vous incontournable des passionnés de sciences et d’images, Pariscience projette gratuitement une sélection du meilleur de la production française et internationale récente de documentaires scientifiques, dans toutes les durées, tous les formats et sur tous les sujets. Pendant 13 jours, Pariscience organisera la rencontre du public avec la science : • du 10 au 18 octobre 2019 à l’Institut de physique du globe de Paris pour le public scolaire, • du 25 au 30 octobre 2019 au Muséum national d’Histoire naturelle et à l’Institut de physique du globe de Paris pour le grand public et les professionnels. Les spectateurs découvriront la science sous toutes ses formes : des longs métrages, des documentaires de télévision, des courts métrages et des vidéos scientifiques du web... Parce que la recherche scientifique ne peut se dissocier des enjeux sociétaux, Pariscience encourage la citoyenneté par le débat d’idées.
Physics Simulations at The Physics Classroom Physics Interactives with Concept Checkers Beginning in the Fall of 2022, Task Tracker and Physics Interactives collide to produce Concept Checkers. Task Tracker is our tool for tracking student progress on website activities. A Concept Checker is an interactive questioning module used to access student comprehension. We have generated more than 50 Concept Checkers for use with the Physics Interactives. And we have incorporated our Task Tracker code directly into several of the Interactives. Welcome to Physics Interactives! Interactives are organized by topic. Topics: 1-Dimensional Kinematics Match an animated motion to a verbal description or a graphical description in the Name That Motion and Graph That Motion Interactives. Visit 1-D Kinematics Interactives. Newton's Laws of Motion Explore relationships pertaining to applied force, friction force, mass, and acceleration with the Force Interactive.

ONE TRILLION TREES: How Children Can Save the World I learned, while doing my research, that trees store carbon dioxide and so planting more trees, of course, reduces carbon dioxide. Trees will transform the CO2 gas into wood and release oxygen. As long as the wood doesn’t decay, the carbon will remain stored and negative climate change will slow down. While planting trees alone doesn’t solve the climate crisis, it gives us more time until we find a permanent solution. Inspired, I finished my report with the words: “Let’s plant one million trees in each country of the world!” A crucial part of the organization’s model is that children teach other children. Climate Justice Ambassadors won’t passively accept the climate crisis. This has a crucial advantage. There are now more than 55,000 trained Climate Justice Ambassadors in 53 countries, including China, Germany, India, Rwanda, Slovenia, Peru, Haiti, Thailand, Nigeria, Colombia, USA, Singapore, Italy, Mexico, Poland, and Switzerland.

CNC Dual Arm Plotter : 11 Steps The blue "arms" L in the above diagram may be regarded as a 2DOF (degrees of freedom) robotic arm with motor M1 acting as the "shoulder" motor. Instead of attaching a heavy "elbow" motor to this arm, a separate motor M2 is connected to the pen by means of a series of light-weight linkages. The final pen position is determined by the resulting parallelogram of forces. Motor choice is not critical other than each motor must be able to resist the "push" from the opposite motor. Maximum plotting area, for a given set of arms, is obtained when motor M2 is mounted directly above motor M1, Construction, however, is greatly simplified if the motors are placed close together as shown. Equations "Plotter Calculations 1" show the required calculations when the input (x) is less than the offset distance for motor1. "Plotter Calculations 2" show the required calculations when the input (x) is greater than the offset distance for motor2. Resolution The plotter resolution varies with distance d1. Accuracy
Réinventer la médiation à l’heure du numérique Vidéo, blog, bande dessinée… Les supports de vulgarisation scientifique fleurissent sur le Web. Mais comment s’y retrouver ? Enquête sur les nouveaux visages de la médiation scientifique. Des tasses de café qui s’entrechoquent, qui se brisent… Le scénario semble n’avoir aucun rapport avec les sciences, et pourtant. ("Un chercheur et son article", de Charlotte Arene et l’équipe de Julien Bobroff, prix "Le gôut des sciences" 2015) La vidéo plébiscitée Avec l’essor des supports numériques, les chercheurs s’exposent davantage sur le Web. « Le besoin de communiquer sur ses découvertes est de plus en plus présent », souligne Julien Bobroff. Si les chercheurs n’investissent pas la médiation sur Internet, elle se fera quand même, mais sans nous ! Depuis plusieurs années, la plateforme vidéo de Google semble être le terrain de jeu privilégié des médiateurs. Les vidéos de Manon Bril, doctorante en histoire, cumulent en moyenne 30 000 vues sur YouTube. Se lancer, mais avec précaution
