We can use phi for potential too, but in France it's used as a general label for scalar potentials, so that we have to use other letters when we define specific potentials (V for the electric potential for instance :) ). There's only one case when we use phi for a specific potential: in fluid dynamics for the velocity potential in non-viscous flows. But that's because it's not much used, so it doesn't need a specific label. And now everyone's looking at me with by big ununderstanding eyes :)) . Christophe. Take your life as a movie: do not let anybody else play the leading role.
