A team from the MIT media lab has created a camera with a “shutter speed” of one trillion exposures per second — enabling it to record light itself traveling from one point to another. Using a heavily modified Streak Tube (which is normally used to intensify photons into electron streams), the team could snap a single image of a laser as it passed through a soda bottle. In order to create the slow-motion film in the video we’ve got after the break, the team had to replicate the experiment hundreds of times. The stop-motion footage shows how light bounces through the bottle, collecting inside the opaque cap before dispersing. The revolutionary snapper may have a fast shutter but the long time it takes to process the images have earned it the nickname of the “the world’s slowest fastest camera.” (via engadget.com)
T-Maze is a tangible programming game designed for kids under 6 years old.
The mission of the game is to help young kids to learn computational thinking while playing games.
In the game, children need to manipulate a group of tangible blocks (with certain semantic meaning) to program a route to lead the role escape from the maze.

India’s Human Resource Development Minister Kapil Sibal this week unveiled the low-cost computing device that is designed for students, saying his department had started talks with global manufacturers to start mass production to launch in 2011.
They actually plan to subsidize the cost of the tablet for its students, to bring the purchase price down to around $20.
“This is our answer to MIT’s $100 computer,” Kapil Sibal told the Economic Times when he unveiled the device Thursday.
In 2005, Nicholas Negroponte — co-founder of the Massachusetts Institute of Technology’s Media Lab — unveiled a prototype of a $100 laptop for children in the developing world. India rejected that as too expensive and embarked on a multiyear effort to develop a cheaper option of its own.
If the government can find a manufacturer, the Linux operatingsystem-based computer would be the latest in a string of “world’s cheapest” innovations to hit the market out of India, which is home to the 100,000 rupee ($2,127) compact Nano car, the 749 rupees ($16) water purifier and the $2,000 open-heart surgery.
