I just read a great short story that some of you might like. It's a combination detective story, hard science fiction, and the history of science called "The Weighing of Ayre" by Gregory Feeley. The link gives the various books it's appeared in; I have it in The Year's Best Science Fiction, vol. 14. It's about 20 years old, but it's new to me.
