IT IS NOT INCOMPRESSIBLE PLEASE READ A BOOK PAST HIGH SCHOOL LEVEL
@gsuberland I'm fairly sure high school physics is where I learned how compressible water is…
by Jernej Simončič � ;
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 if i learned one thing from stockton rush, it's this

@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.

@gsuberland oof you answered the bucket direction thing? RIP 🪦

@gsuberland Here I made you a meme.

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