@gsuberland I'm fairly sure high school physics is where I learned how compressible water is…

water's compression properties are admittedly *weird* due to having a variable bulk modulus that also depends on the pressure, but even without understanding the details it's trivial to look up that the same mass of water on the surface and bottom of the ocean differ in volume by about 1.5%


@gsuberland imho the weirdest thing about water is that it gets bigger when it freezes

@gsuberland I think I watched a YouTube explanation after Titan accident, and one of the explanation why the implosion is so violently rapid is because the water is somewhat compressed at that level of pressure.

@gsuberland I got schooled on this when optimizing an ocean circulation model. Computing the equation of state for sea water was a lot of the total computation... compressibility and salinity, mixing and advecting water packets up and down.

There there’s the bomb people who are like “oh sure let’s compress the plutonium so it becomes a critical mass” .. think about that, that’s not just water it’s a super dense heavy metal.

Anyway yeah, the more you know, the more “it depends” is the answer.


@acsawdey funnily enough the context for this was a shockwave travelling through water, and I didn't even mention water's compressibility (or otherwise) because I was talking about the water as a momentum transfer medium.

@gsuberland *nods* everything is compressible, if you’ve got enough force
