Hi there Griffiths uses a nice notation for the vector from the source point to the field point --a "squiggly r" -- in his E-M textbook. He calls it a "script letter". It makes many ugly expressions look much simpler. Anyway, nice as it is, does anyone who has used Griffiths know how to produce that "squiggly r", in LaTeX or using some standard symbol font? I'm trying to typeset some stuff and I've been stumped trying to find it! Thank you!
