I recently took the Which Science Fiction Writer Are You? quiz and discovered that I'm Hal Clement. I subsisted entirely on a diet of science fiction from ages 13 to 16, but I don't recall reading any of his stuff. I came close to reading all of Arthur C. Clarke, Isaac Asimov, Poul Anderson and, yes, Edgar Rice Burroughs. But no Clement. So I got on eBay and bought a Book Club edition of Mission of Gravity (1954), and have just finished it. And now I know who I am.
The thing I like about Clement (or should I say Stubbs; Clement was his middle name), and the thing that readers who like him like about him, is the fun he has with scientific fact. He gathers together a set of physical properties for his locale and these provide the story logic. The setting for Mission of Gravity is a huge planet spinning so rapidly that it's about twice as wide at the equator as it is from pole to pole (see cover illustration), which means that the effect of gravity varies from latitude to latitude. The behavior of hydrogen, methane and ammonia under these conditions create plot points of their own. The physiology and psychology of the indigenous characters (caterpillars with a fear of falling) flow logically from the setting. He sets the rules, then follows them, making the book an enjoyable mental game. Which is what science fiction ought to be. Two quibbles though: wouldn't the air pressure vary from latitude to latitude? And would humans and caterpillars really get one another?
This is old school, "hard" science fiction, which I don't think gets written much anymore. But, with all these new exoplanets coming into view, maybe it's time for a second hard wave. Here's a title: Hot Jupiter!
