Richard Dawkins writes about science writing here. A couple of noteworthy comments:
“Prick your reader’s imagination with a stunning fact, or a fresh metaphor, or by turning a familiar fact dizzyingly upside down, or by filtering it through the alien lens of a Martian eye. However useful science may be, and however relevant to everyday life, that is the least important thing about it. Science is, above all, wonderful. You may write to inform. You should write to inspire.
No scientist has won the Nobel Prize for Literature. Why not? I suspect that it simply hasn’t occurred to the judges. “Literature” automatically conjures “novelist”, or “poet”. Yet, could there be a better subject for great literature than the spacetime fabric of the universe? Or than the evolution of life?”
