For a post-tenure review I need to write a description of my current and future research, and I decided I wanted to write about the past as well. I have done history of the space program, history of women in science and engineering, and history of forestry (environmental history). Amazingly when I try to put that all together it actually looks not like random wandering but like a a coherent story. I'm asking very much the same questions about forestry that I was about the space program, about the intersection between research and everyday practice. The history of women in science weaves in and out of that.
