My physics teacher takes the spherical roast beef as an example for heat convection.

One of the cool facts about gravity is that the gravitational field of a body 'feels' spherical at a distance, even if those bodies are not spherical themselves. There are higher multipoles but they are increasingly suppressed the further you are from the body. So at least for gravity the spherical approximation turns out to be good and justified.

Anna Cramling, women’s international chess master, should review this paper, having popularized the Cow Opening.
