Most people in our society use computer technology every day, and depend upon it (for government and tax records, banking, medical records, etc.), even if they never touch a computer themselves.

The activity was inspired by the Viewpoints article "The Computer as a Materials Science Benchmarks"(1). In the description of how advances in materials chemistry have led to our ability to visualize information through the computer, there is a note describing how to see the red, blue, and green contributions to each pixel using a magnifying glass.
