They just want researchers in the enclosure to feel enriched and stimulated. ('The Enclosure' is what archivists call the shadowy world outside their archives in which so many people are trapped.)

As a first step, they can put in a secondary deck, to help drivers try it out and find out how fun the jumps are. After a while no one will use the old flat deck and they can remove it.

It was great until my thumb slipped and I accidentally launched my telescope into the air at Mach 8.

If only my ancestors had been fortunate enough to marry into the branch of the bacteria family that could photosynthesize, like all my little green cousins here.

Transcript:

[Cueball and Beret Guy, seen from afar in silhouette, are walking up a grassy hill.]

[They continue walking up the hill, reaching its grassy summit. Now with normal lighting. Beret Guy is a bit ahead of Cueball.]
Beret Guy: I learned something today.
Beret Guy: I went on one of those family tree sites and kept clicking back, and it turns out I'm related to stromatolites!

[Closeup on Cueball. Beret Guy's reply comes off-panel from a starburst on the right edge of the panel.]
Cueball: The bacterial mats?
Beret Guy [off-panel]: Yeah! A few billion years back, on my mitochondria's side.

[Cueball and Beret Guy standing on the top of the grassy hill facing each other. Berety Guy holding a hand out towards Cueball.]
Beret Guy: My Archaean ancestors absorbed some bacteria that were cousins of stromatolites. That's how I got mitochondria.
Beret Guy: Cell nuclei, too.

[Cueball is standing behind Beret Guy who is now sitting down in the grass leaning back on one arm with the other arm resting on his bent knee.]
Cueball: I think there are still living stromatolites. You could get in touch.
Beret Guy: Nah, they're probably busy. I don't want to bother them.

[Cueball is sitting behind Beret Guy who is now lying down, both again shown in silhouette from a far, revealing they are on the top of the grassy hill.]
Cueball: So what are you going to do with this knowledge? Nothing?
Beret Guy: Lying on a hill in the warm sun is an old family tradition.

It struggles a little with complex positions, like when there are an even number of moves and it has to round down, but when run against itself it's capable of finding some novelties. At one point I saw six knights on the board at once; Stockfish rarely exceeds four.

They should add a little sticker that certifies that the humidifier supports water conservation, but in the sense of energy conservation or momentum conservation.

They're continuing to search for a square with the same area as the circle, as efforts to construct one have run into difficulties.

Transcript:

[In a single panel, White Hat, Ponytail, Miss Lenhart, Cueball, and Megan are standing in a field. Ponytail is holding a notebook and taking notes, Miss Lenhart is kneeling and holding her hands on a circular object with the radius marked on it, Cueball is holding a large caliper-like measuring instrument, and Megan is taking a photo with her phone sideways.]

Math breakthrough: Dimensional analysts have discovered a real unit circle. Once they measure it, units can finally be added to all our geometry textbooks.

Can you pass the nackle?

Transcript:

[Cueball is holding a pointer and gesturing towards a whiteboard that shows the chemical formulas HCOOH and CH₃COOH. Below these, respectively, are classic diagramatic representations of formic/methanoic acid [with an apparently accidental doubled bond between the carbon and the hydroxy group] and acetic/ethanoic acid; being, in turn, a single- and double-carbon chain molecule with a double-bonded oxygen (carbonyl group) plus an oxygen-hydrogen (hydroxy) upon one carbon of each, to form the full carboxyl grouping, and hydrogens completing all other expected bonds.]
Cueball: The two simplest carboxylic acids are hakoo and chuckoo.
Off-panel voice: No!!

I wonder what surviving human held the record before balloons (excluding edge cases like jumping gaps on a mountain bridge). Probably it was someone falling from a cliff into snow or water, but maybe it involved something weird like a gunpowder explosion or volcano.

I don't dig pit traps and cover them with sticks and a thin layer of leaves nearly as much as I expected; I find a chance to do it barely once a month.

You may notice the first half of these instructions are similar to the instructions for a working nuclear fusion device. After the first few dozen steps, be sure to press down firmly and fold quickly to overcome fusion pressure.

The most important quantity for meteorologists is of course the product of latent pressure and temperostrophic enthalpy, though 'how nice the weather is' is a close second.
