    hey pf! can someone please tell me if my understanding of the material derivative operating over some scalar [itex]\rho[/itex] is correct? basically, from my understanding if we take [itex]\frac{ D \rho}{D t}[/itex] this will tell us how [itex]\rho[/itex] changes as time changes AND how [itex]\rho[/itex] changes as we move our little piece of [itex]\rho[/itex] through space. is this correct?

    Yeah, I would say that's pretty much correct.
