-ologist

But my lack of scientific training presents one distinct advantage: Because I don't know the scientific reality, I can conceive a story that a scientist might think outlandish, learn enough of the science in the fields that interest me to tell the story plausibly, and then people the novel with engineers and experts and every sort of -ologist and live vicariously through them.
