Low magnification SEM image of open cell polyurethane foam
If a gas is injected into a liquid it forms a cellular foam structure. When a thermoset prepolymer of low viscosity is foamed, the polymer can drain from the cell walls (driven by surface tension) before it sets at the cell edges, leaving an open-celled foam. The cell edges have three concave sides, giving rise to the tri-cuspid cross section visible at the bottom of this image. The average co-ordination number for the nodes (where struts meet) is four, giving tetrahedral junctions.

Computing in the Cloud - Part 2: "Possession and ownership of data" – January 14, 2008
"Computing in the cloud" is one name for services that run in a Web browser and store information in a provider's data center — ranging from adaptations of familiar tools such as email and personal finance to new offerings such as virtual worlds and social networks. This workshop will bring together experts from computer science, law, politics and industry to explore the social and policy implications of this trend. Part 2 includes the first panel of the workshop, entitled "Possession and own

Brian Kernighan: The Changing Face of Programming
The rapid evolution of languages, tools, environments, and expectations presents major challenges and opportunities for programmers and for software engineering education. This is true across all kinds of programming, but is especially so for Web systems, which are now routinely written in untyped scripting languages and include Ajax, mashups, toolkits, frameworks like Rails and Django, and a profusion of interfaces, all operating asynchronously on distributed systems. For the past 7 or 8 years

The Confederacy's Last Stand
In March 1865, Confederate forces experienced a flicker of hope for victory after hitting General William Sherman's Union troops hard in North Carolina. Johnson had a faulty map and the North won because of the limited knowledge Johnson had. Sherman now marches through the South, 650 miles, in 100 days. He captures three state capitals, loses very few men, and the South is left to realize that continuing the war is futile. (4:01)
