comment Would a sea level rise (on the other side of the Earth) if you would dip your finger into the ocean?
Pascal's law assumes the fluid is incompressible. It also requires the fluid be confined.

comment Why does a dielectric have a frequency dependent resistivity?
keeping with a classical treatment, I see it more as a voltage source reversed than a resistor. Either way, you do experience a voltage drop across the dielectric and its proportional to the polarization (so basically compute the potential generated by the polarization.) If you're ok with differential equations, you could model the capacitor and solve for V (t).

comment Mass is a stuff or not?
laymen language often uses mass for "stuff", but in physics it is a property describing inertia (resistance to change in velocity)

I mentioned only spatial decay, not temporal decay.

A formal treatment would rely on Navier Stokes and volume viscocity, but just thinking of the bulk modulus for simplicity as you draw large concentric rings around the point where you put your finger in. The expression (dV/V) dV is change in volume, V is total volume. As you consider larger and larger concentric circles, dV stays the same, but V is getting larger, so the ratio dV/V is getting smaller, thus dP (change in pressure) is getting smaller as you go further away from the perturbation point.

True, I assumed the question was about the steady state solution after all the transients have passed.

comment In a large city how much hotter on average is it outside due to the air conditioning of all the buildings?
good question. I speculate that it's not a significant contribution.
