Recently I saw an animation
named “The inner life of the cell”, which was made by Howard Hughes Medical Institute and Harvard University Biovision. It can be watched online only:
UC Berkeley shows the class video at youtube!
As the mit show the OCW, the berkeley relases the class video at youtube, which could benefit the students all over the world. Enjoy it!
A fluid flow video
I just remembered another video that I had seen some time ago. Many of you have probably seen it but here it is for those who have not. (The original page where I found it is http://www.maniacworld.com/Laminar-Reverse-Flow.html.)
Prof. Pat McMurtry's explanation is:
Eigenmodes of a square plate
The following video is a nice depiction of how the eigenmodes of a plate change with increasing forcing frequency.
An interesting coupling

Sony announces a OLED display on plastic film.
This is apparently the world's first full color OLED/organic TFT on a flexible substrate. Sony managed to create a flexible display with a size of 2.5 inch featuring a resolution of 120×RGB×160 pixel.
Other specifications of the flexible OLED display include 100 cd/m2
brightness, 1,000:1 contrast ratio and 0.3mm thickness of the panel.
