Good question! Are we in a vacuum?
Of more interest is that the interest in this topic has been dropping as well. I has halved at each new posting, and was not high to begin with.
As the Engineer said, paraphrased, "interest is close enough to zero for practical purposes".
---- caution politically insensitive matter below ---
For those not familiar with the joke it is a variant on zenos' paradox. There's a game show and they bring out a mathematician and an engineer, both male. They then open a curtain and a gorgeous lady stands before them, equal distances from each.
They both cheer up considerably.
The host says "I will ring a bell periodically, and each time, you will each move half-way to this beautiful lady".
The mathematician immediately looks distressed, and sits down and cries.
The host asks why -- he says "if I can only move half-way each time, at finite intervals, I can never quite get there. I quit".
The Engineer however is grinning and happy. The host now asks him "why are you so happy, did you not hear? Do you not understand math?"
The Engineer just smiles and says "but I can get close enough for all practical purposes".
--- we now return to this thread unfortunately probably still in progress, with interest at terminal velocity for sure ---
