Researching real-life scientists for a book about physics, a novelist friend told me she discovered that eminent scientists sometimes seem to cultivate the image of the genius who lives just on the other side of a partially collapsed wall from lunacy. She spoke of meeting great scientists who demonstrated a flagrant, near-hostile disregard for conventions of dress or conversation, scientists who prided themselves on walking away mid-sentence. (Of course these scientists were never women. Women must continue to labor under the constraining, bland yoke of professionalism.)
