The Art of Science Communication: William Zinsser on How to Write Well About Science

This principle of science writing... teaches the writer to lead the reader, step by step, from knowing nothing about a subject to understanding enough to grow enchanted with its broader significance....
Imagine science writing as an upside-down pyramid. Start at the bottom with the one fact a reader must know before he can learn any more. The second sentence broadens what was stated first... you can gradually move beyond fact into significance and speculation ...
consider the importance of cultivating a layer of wisdom above the layer of “significance and speculation.”... when one reads the very finest science writing... one walks away informed... elevated and enriched and illuminated with a new appreciation of our “strange and shimmering world.”
