prof_brotherton just announced the launch of a free SF anthology funded by the National Science Foundation. I hear the NSF pays pretty well, so there must be some good stories there. :)
Mike, a PhD in astronomy, edited the anthology, and the intention is that the stories, beyond sheer entertainment value, can be used in classrooms to teach astronomy concepts. How cool is that?
Stories by: Jerry Oltion, Alma Alexander, Wil McCarthy, David Levine, Jerry Weinberg, Mike Brotherton, Dan Hoyt, Mary Robinette Kowal, Valentin Ivanov, Jeffrey A. Carver, G. David Nordley, Kevin Grazier and Ges Segar, Alexis Glynn Latner and Geoffrey A. Landis
