“sometimes what works satisfyingly for a time is subsequently found replaceable

—“sometimes what works satisfyingly for a time is subsequently found replaceable by something that works even better — for example, the discovery that Newtonian mechanics is a special case of relativistic mechanics that holds exactly only in the limit of v approaching zero, but is “good enough” an approximation for most government work when v is << c)”— Frank Lovell

Posting to my site today, found this quote from Frank.

The interesting thing is that this also means “at human scale”.

In other words Human Scale is approximately equal to v, where v is approximately equal to zero.

We perceive the universe slowly.
