This Summer Mechanics Course is offered on the MIT-Harvard edX.org platform for teachers who want to increase their appreciation of Mechanics, their problem-solving ability, or who might consider using our pedagogy, automatically graded homework, and hundreds of other free online resources in their class. Those who only want to browse are also welcome.
This course targets physics teachers. There is a special discussion forum on how to teach this material, Massachusetts teachers can receive Professional Development Points, and all teachers can receive Continuing Education Units from the American Association of Physics Teachers at ½ of their usual rate. Instructors are encouraged to share this announcement with their colleagues and to suggest this course to accomplished students whom they think would enjoy or benefit from a more mature overview of mechanics and problem solving.

New Exploratorium Opens in San Francisco - Apr 17, 2013
Science is comprehended not through abstract principles but through concrete experience. It is revealed not through speculation but through manipulation. We learn by exploring. two recently released free Exploratorium apps for iPads, one dealing with sound, the other with color. They show with compact simplicity how even commonplace sensations become sources of insight. Or look at the Exploratorium itself: drink deep from the water fountain shaped like a toilet. Sit in a chair holding a spinning bicycle wheel. See whether you and three other visitors with incomplete controls can collaborate on a game of Pac-Man. Wear a set of headphones that seems to swap your right and left ears. Climb into a kaleidoscope. It imbues a childhood wonder we all are born with - an excitement for science.
