Graduated with BSc in Engineering Physics in 1953, then well after retirement, an MSc in Astronomy in 2009. I have a deep interest in the physical sciences and find the questions in this site to be a great learning experience.

comment How fast would body temperature go down in space?
Jkej,a nice analysis assuming no incoming radiation from Earth and Sun, which would increase your freezing time estimate.

comment Function for heating of a planet by its star
Clouds are not the only albedo factors. Checkout albedo on WIKI. The greenhouse factor is mainly determined by water on Earth, but other planets like Venus and Pluto have carbon dioxide and methane factors that dominate.

comment What determines the angle of the cushion on a pool table?
One factor that was likely considered was to minimize the likely hood of high speed balls bouncing off the pool table. Perhaps the current cushion angle was found to be optimal for this situation.
