Re: capacitance to free space

Hi Jared and Larry,

Be sure to check this out:

Like I think they got to the point of doing toroid free space capacitance 
to like 40 decimal places, if not "perfect"!!!

Sort of heavy math, but glad to know people are really getting a super good 
handle on this stuff ;-)))

Cheers,

         Terry
