The half-mile 'Line of Questions' interpretive walk on the NASA Ames Research Park Campus was designed to extend the rich and complex dialogue that is taking place during the 2009 Summer Sessions of the International Space University and Singularity University. Questions and thoughtful images are posted weekly on signboards along a walk composed of simulated, large-scale resistors and IC chips. The trail marks the daily route for the 131 participants and reflects the fact that NASA Ames is both home to one of the world?s fastest super computers and is NASA?s lead IT center.
