Thus, I also believe there are lessons from cloud computing that are potentially applicable to computational science applications.

I pedaled home in time to watch the Apollo 11 lunar landing later that afternoon, holding the cardboard model of the LEM in my hands. That…

All too often, though, I fear that our educational system punishes curiosity and rewards conformity. Only a small fraction remains sufficiently iconoclastic and self-confident to resist, asking those seemingly annoying questions that defy authority…
