RE: Let us know when...

While the math might be 8th grade, the concepts JN discusses are probably 12th grade physics. Up to the challenge?

As a starter, notice the following statement from the first paragraph of JN's post you linked:

    The relation between inductance, capacitance, and dielectric of a double braid coax is the following...
    L * C = 1031 * DC...

    L is in nanohenries per foot
    C is in picofarads per foot
    DC is the dielectric coefficient of the insulation between the braids.

Clearly JN is discussing a specific construction of a coax cable consisting of two concentric tubular conductors of different diameters separated by a dielectric. The relationship JN provides applies only to that configuration and not to the general case as you seem to imply.

I think you've misunderstood what JN was attempting to do back then.

Be well!
