All astronomical bodies, from moons and planets up to galaxies, spin and have orbits. Spin is also a key characteristic of subatomic particles. Yet in our human world, we are relatively static.

Just before the start of totality, someone noticed that the shadows formed through this "pinhole camera" onto a white board were so sharp that the individual hairs on my arms were visible. How thin must the solar crescent be for the shadows to be this sharp, and how soon before totality would this occur? October 2. 01. 7. Recently, my wife's silver car became covered by a swarm of flying ants. This was odd because none of the other cars parked nearby had any on at all.

A friend mentioned it had happened to his silver car too and after searching online it seems it's a known phenomenon. Why is it that the swarm seems to be attracted to something silver? Watch The Honeymoon Killers Online (2017) here.
