The periodic table of elements is a usual example.

There were holes in it placeholders for elements
or atomic species, later discovered.

The usual account since antiquity was that stringed
musical instruments could be made reproducible their
sound according to a theory of construction.

That physics or its science has got a ways ahead of
the mathematics, still has that there are tons and
tons of old-fashioned and considered obsolete the
physics, for example "Faraday Rotation", that simply
enough just need mathematics to bring them right back.

Otherwise though it's usual that only after the
un-attainable sort of theoretical results of the
fundamental physics of the 20'th century was it so
that experiment can't explain itself.

The motive power of steam engines definitely made
much for the study of aspects of the triple point
of water, yet as well, accounts of pneumatics and
the letter-tube delivery systems or even how a
train locomotive makes its way up the tracks,
for example from the World Factbook of 1846,
make for theory meeting practice.


Here are some podcasts or video essays I recently
recorded.

"Reading Foundations: double relativity"
"Reading Foundations: continuous quanta"

Some books looked at include "The Grand Contraption"
and "The Powers that Be".



Back to the idea of implementing a divider circuit,
it's kind of funny that there isn't really a great
example of an analog divider circuit that's sort of
ideal and efficient, besides as for usual accounts
of amplifiers and attenuators and so on. There are
integrators and the like, accumulators, there's a
place on the chart of ideal electrical components
looking to be filled with a rational divider.
