No, Spiffor. It's a Math thing. 
Ok, Jon, here's one for you, One that I didn't solve.
We have an equation in the La-place (sp?) form:
d2u/d2x+d2u/d2y=0
find u(x,y) or u(r,teta)
outside the circle x^2+y^2=4.
with u(x,y) on the circle's edge u(x,y)=y
u(r-->infitnity)=0
write u as a function of (x,y) or as a function of (r,teta).
