random noise term. One consequence of this approximation of the fast degrees of free-
dom by fluctuating forces is that the energy and momentum are no longer conserved,
which implies that the macroscopic behavior of the system will not be hydrodynamic.
In addition, the effect of one solute molecule on another through the flow of solvent
molecules is neglected. Thus, BD can only reproduce the dif
