Well, the future may not need us, but at Rice University, the future does (optionally) need Howard Lovy's NanoBot.
The Houston center of higher nanotech learning has a new course this fall: Nanotechnology: Content and Context. It sounds like a fascinating course, and needless to say I'm glad the issue of "context" is being addressed since I blab endlessly about it on this site. Perhaps that's why the NanoBot is listed in the class syllabus under background and optional reading.
Hello, eager young nano cadets. Welcome to my little world. And, yes, this will be on the test.
