understanding the average height of a unit hyper-semisphere
On a high-dimensional sphere most of the mass is concentrated around the equator, where the height is lowest. That's a heuristic explanation for why the average height goes to zero. |

What's the variance in the Six Degrees model?
This is one classic paper on the search problem: cs.cornell.edu/home/kleinber/swn.pdf ... and in general it's a good entry point into the literature. |

what-if.xkcd.com: stabbing (simply connected) regions on the 2-sphere with few geodesics
In the case of the US, which fits in a hemisphere, it might simplify things slightly to use gnomonic projection to reduce to the analogous problem with lines and plane regions. |

Dynamical properties of injective continuous functions on $\mathbb{R}^d$
Thanks! In light of your comment, I added your good point about a stronger downward component and made the wording overall a bit less tentative. |
