The last time that I built an antenna I used the formula to get the

Did "the formula" take into account any insulation, conductor resistivity,
conductor diameter, height above ground, characteristics of the ground,
and objects in the near field including supports?

If not, what is your point?

The point is that those items are not part of "Antenna Theory: The
Science" but are a large part of "Antenna theory: The Art". Art has been
talking as if they are one and the same.

Science is fully accounting for all variables and their effects giving
you exact answers.

Art is experience and rules of thumb that get you close enough.

As I understand it, science is trying ideas out to see what happens in
the real world. That would involve "experience" to a certain degree, as
an "educated guess" is involved in the design of the experiment.
