resistivity

Like maybe pH goes with the square of resistivity or something?

While getting a physics degree, I had a lab where we measured resistivity.

Carrots have a much higher resistivity than nice salty, juicy hot dogs.

If the ground has high resistivity and current flows through it there is a voltage difference from one point to the next.

While there's a mild difference there, I'm not sure it'd be easy to detect, particularly as it has a very low resistivity to begin with.

I wonder if Kamerlingh Onnes' rationale in 1911 to cool down mercury and measure its resistivity was simply: "I wonder what happens at low T?

Different manufacturers use different models to map resistivity data to BF%, so for the same person one can get rather different answers.

This resistivity is roughly equivalent to present-day efforts.

X-rays, neutrons, resistivity, clever weighing, optical techniques, microwaves, touch probes, three-year-olds, lemurs, optical imaging, you name it, it's probably cheaper, better, and faster.

Then they might conduct electrical resistivity tomography to directly measure and image the density of subsurface material to identify water pockets and narrow down good drilling spots.

"Standard" low-Tc superconductivity appeared "impossible" under the usual models of materials' resistivity, but even that was merely a violation of a well-tested model when it was extended to a previously untested very-low-temperature regime.
