But I knew Eric to have exceptional ideas from 1975 when we were both at the Space Manufacturing Conference at Princeton. By the 1979 conference, when he started talking about nanotechnology, we had written two papers jointly, one on using vapor phase manufacturing to build large structures in space, and another on dust-filled radiators to get rid of waste heat in space. Both papers were mentioned favorably by the conference organizers, and we filed for patents on them. Alas, the patents have long expired, because we were way too far ahead of time.<o:p></o:p></p><p class=MsoPlainText><o:p> </o:p></p><p class=MsoPlainText>I think Eric recommended _The Selfish Gene_ to me. It deeply influenced my thinking and eventually led me into evolutionary psychology.

You post here like you are just another one of the lads, yet you have done all this cool stuff. I have been around you enough to know, you never go around acting like a bigshot, when if you did, it wouldn't be an act: you are an actual bigshot.
