Quick lesson in mine ventilation since a big YouTuber did a video about WIPP. Mines have different ventilation circuits to get fresh air where it needs to go. You learn a lot about these because you need to know where the bad air is if there's a fire.
A map of the WIPP underground with the different ventilation circuits crudely highlighted. Air comes in from an air intake shaft in the west, and goes to a north circuit as well as a construction circuit to the south. The north circuit goes around some drifts including where I worked then out the exhaust shaft. After passing through the construction circuit, air goes on to the disposal circuit, passing through the waste panels before exhaust out the exhaust shaft. There's also a tiny waste shaft circuit directly between the waste hoist and the exhaust shaft.

Some of my math art. It's a 3D printed lamp that stereographically projects a hex grid. It's actually customizable to project arbitrary patterns, and I have some plans to improve it that I haven't gotten around to yet.

A 3D printed lamp, spherical in shape, with legs on the bottom half and a pattern of hexagons on the top half. The light inside projects a grid of hexagons on the ceiling. The same lamp, off, shown from above on a table.
