Stellar mass vs. radius

Theoretical models are still systematically off in their predictions of the stellar mass-radius relation; see page 33 of http://arxiv.org/pdf/1211.2527.pdf

...but the discrepancies are probably just due to uncertainties in the input physics and approximations used, not to fundamental flaws in our understanding of the universe.

Science Communication Resources

From a "Journalism 101 for Scientists" workshop I attended here at York:

Science Media Centre of Canada (click on "For Scientists")

* Publications for scientists from the U.K. Science Media Centre

* Books to look for: "Escape from the ivory tower" and "Don't be such a scientist"
