Free-Range Professors
Sunday, November 4th, 2007As I’m pulling a battery out of a plane, getting ready to charge it, Dwight is telling me about his diffraction grating project.
“My plan is to use a computer to drive an ultra-high-resolution plotter,” says Dwight, “then I’ll photo etch that image onto a sheet of reflective Mylar.”
Usually I manage my role in exchanges of this sort with cyclical sounds of agreement and understanding. “Uh huh.” Wait 30 seconds. “That’s interesting.” Another interval. “Wow.” Iterate.
