X-ray tomography 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. The average co-ordination number for the nodes (where struts meet) is four, giving tetrahedral junctions. The deformation behaviour of the foam was observed by X-ray microtomography at the ESRF i
GS-05: Adding transitions between pages and states
In this movie, learn about the unique interaction-based Timeline in Flash Catalyst and how to create transitions that animate or move between two states of a design.
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.
