I'm about 2 weeks into an 18 day trip. I started in DC where I gave a presentation on the history of the space elevator to the Society for the History of Technology. The theme was that of reconverging technologies in the guise of the space elevator and the talk drew upon research Mary and I have did.
Next was the Nano-Image meeting in Columbia, South Carolina. This meeting brought together scientists, nano & society people, and art historians to talk (in excruciating detail) about the various uses and types of images at the nano-scale. What I took away from the meeting was that even among people who purportedly study nano, understanding of the topic is often lacking.
I'm now in Princeton where I'm looking at the papers of a physicist who Eric Drexler worked with in the 1970s. Tomorrow it's on to DC(again) for the History of Science Society meeting and then back to California. Whew.
