Biggest Daytime Fireworks Show Ever -- Mathaf Opening of Cai Guo-Qiang: Saraab
YouTube Uploaded by nateiu on Dec 6, 2011
"At the Arab Museum of Modern Art in Doha, Qatar this week, Chinese artist Cai Guo-Qiang put on his largest "explosion event" of the last three years, utilizing microchip-controlled explosives to form incredible designs and patterns. The video we've embedded of the event is an impressive testament to how a volatile black powder explosion can be controlled and shaped by computer.
Each set of explosions was calculated to paint a different picture. One series of explosions created black smoke clouds that looked like "drops of ink splattered across the sky."
In another, 8,300 shells embedded with computer microchips exploded in a pyramid shape over the desert."

Video Camera Captures a Trillion Frames Per Second
Visualizing Light over a Fruit with a Trillion FPS Camera, Camera Culture Group, Bawendi Lab, MIT
YouTube Uploaded by cameraculturegroup on Dec 11, 2011
"Video of a fruit illuminated by a femtosecond laser pulse and captured at an effective trillion frames per second. Light moves less than 1 mm per frame.
We have built an imaging solution that allows us to visualize propagation of light at an effective rate of one trillion frames per second. Direct recording of light at such a frame rate with sufficient brightness is nearly impossible. We use an indirect 'stroboscopic' method that combines millions of repeated measurements by careful scanning in time and viewpoints.
The device has been developed by the MIT Media Lab's Camera Culture group in collaboration with Bawendi Lab in the Department of Chemistry at MIT. A laser pulse that lasts less than one trillionth of a second is used as a flash and the light returning from the scene is collected by a camera at a rate equivalent to roughly 1 trillion frames per second. However, due to very short exposure times (roughly one trillionth of a second) and a narrow field of view of the camera, the video is captured over several minutes by repeated and periodic sampling.
