Thanks Hans. Great historical context of a complicated domain "yet not even the beginning of a way to the goal had been made clear, for people simply played about with Maxwell’s equations, but not with the ideas of Maxwell or Faraday; it was a mathematical game and not scientific research that was pursued..." Theory before experimentation? Franklin and others vs the maths? Franklin said he could maybe explain how electricity might work, but not what it was.
I can give you a number of usefully precise mathematical descriptions of how gravity behaves but neither I nor anyone else on this planet can tell you definitively what it is.
As a species, but especially among the academic disciplines, we do not like to admit that we so often put labels on things we cannot explain, more as a pretense to understanding them so that we can then hide from ourselves, than as a measure of true understanding. Thanks for the quote!

Nice slide rule.
The reverse side (shown in that photo) has a bunch of custom RF functions.
