I am using E-Tesla5 to try and figure out this distributed C thing and
early results look promising!!  Stay tuned..., there are still about 10
trillion calculations to go (that is not a joke!).

While waiting for the programs to crunch numbers I figured out the first
fudge factor.  The half plane to surface area constant 6.611 I fudged is
really 2/3 x pi^2 or 6.579725....  Which is 0.458% lower.

Now to find that statics book...

Cheers,
