The Steppenwolf: A proposal for a habitable planet in interstellar space
Rogue planets have been ejected from their planetary system. We investigate the possibility that a rogue planet could maintain a liquid ocean under layers of thermally-insulating water ice and frozen atmosphere as a result of geothermal heat flux. We find that a rogue planet of Earth-like composition and age could maintain a subglacial liquid ocean if it were ~3.5 times more massive than Earth. If a rogue planet had about ten times higher water mass fraction or a thick cryo- atmospheric layer, it would need to be only ~0.3 times the mass of Earth to maintain a liquid ocean. Such a planet could be detected from reflected solar radiation and its thermal emission could be characterized in the far-IR if it passed within O(1000) AU of Earth.

He asks the reasonable question; what fields would be necessary for fantasy writers?
I, on the other hand, wonder just how widely read in the field is anyone who gave the above advice? Did they think it took a Ph.D. in physics to write Honor Harrington or years of research in the field of biology to come up with Protector?

Then:
Now:
Randy McDonald drew the obvious parallel yesteryday.
Embattled Egyptian President Hosni Mubarak says he will stay in office until the scheduled presidential election in September, drawing the outrage of thousands of anti-government protesters demanding he resign after 30 years in power.
Now:
Egyptian President Hosni Mubarak has resigned on the 18th day of anti-government protests, and handed over power to the military.
