  • Cooling by radiation is slower than convection or conduction, but it still happens. The James Webb went from room temperature to deep cryogenic in a few months, and it’s big. As for moisture, things cook off into a vacuum very easily. That’s the foundational to the whole concept of freeze drying, actually.

    Freeze dried wood is absolutely commercially available, if pricey. I have no idea if anyone has used it for musical purposes either. There’s a lot of audiophile-ish magical thinking in that space so it’s possible nobody has bothered.

    Edit: Although, since this is a research project, maybe not freeze drying it first was the point.










  • Yes. People seem to think the bends always happens on exposure to weird pressures, but it just doesn’t. I guess they’re understandably imagining it’s the same as hot or cold.

    (though no idea about the effects on the human body from such a sudden change)

    Well, enough delta p is entirely capable of squishing an entire person through a thumb-sized hole, and while there’s no hole here I image there’d still be some sort of shock wave, and the air already in your lungs returning to normal volume suddenly would be uncomfortable. Don’t go too deep the first time, definitely ease into it.

    Interestingly just 1 atm is fairly harmless. The first time someone got caught in a vacuum chamber they weren’t sure what they’d find, but the guy just got up and said his ears hurt.


  • So then I guess C is salamander. Also lays eggs and lives by a pool, but doesn’t do anything extra, and is a necessary step before most of the other modern languages.

    COBOL is a coelacanth. To everyone’s surprise, they’re still out there. We thought they were an old, very extinct example of a non-terrestrial lobe-finned fish, but they actually hung on in some odd environments. They cause massive indigestion to anyone that has to consume them.

    If Node is a mosquito, Javascript itself is another hymenopteran: the yellow jacket wasp. Just as hated, and with a tendency to injure handlers, but widely successful and defended as filling an actual useful role in nature. They build delicate, arguably pretty nests.
