What is the coefficient compressibility β here in the density formula?

25 August 2022 1 5K Report

The crust density can be described by this formula, which is the fuction of temperature and pressure. What value is the coefficient β?

Ulrich Deiters

It is probably the isothermal compressibility, usually called kappa_T = -1/V (d V /d p) = 1/rho (d rho/d p).

Is there a deep reason for using the squared modulus of the wave function as the probability density of the existence of the particle?

I think we were all surprised at the first time we got to know quantum mechanics that the squared modulus of the wave function is the probability density of the existence of the particle? The role...
