 So i modified the mean density to be 10, set [[latex($\alpha=-2$)]] so [[latex($\beta-1$)]] and strengthened the perturbation.

 In all of these, there was initial pressure equilibrium (so different temperatues), although I was using a gamma=1.001 which assumes an isothermal gas.  Consider what happens when a gas at a density of 1 and a temperature of 100 K mixes with a gas at a density of 100 and a temperature of 1 K.

+Unless the dense blobs are gravitationally confined.  But how to go from a power spectra of density fluctuations to a mass-size relation?  We have [[latex($\hat{\rho}(\mathbf{k}) \propto \exp^{A|k|^{\beta}}$)]]?  If [[latex($k << \lambda_k = c_s\sqrt{\frac{\pi}{G}} \rho^{-1/2}$)]] then the fluctuations should be jeans unstable - but \rho = }
