Whenever I think about protecting the environment, I think about preventing the catastrophes that are wars.
Finding the thorium line is one of the most important open problems in precision/fundamental measurement.
Tides are largest at full moon and new moon, when their gravity gradients combine to enhance each other's tides. A week later, their gravity gradients interfere, decreasing the amplitudes of the tides.
As a consumer, I recently selected a new device in large part because its cloud-affiliated software (and bespoke operating system) was written, stored, and administered in countries with appropriate and ethical legal frameworks. The competition was more feature-complete, but I concluded that I couldn't trust any of those options.
Thus, it is impossible to perform the suggested procedure. We don't (and probably can't) know what zero potential looks like.
Furthermore, we would probably measure those potential differences using clocks that rely upon the SI as presently defined.
It even makes a voltmeter read incorrectly.
Moon-meters would be different from Earth-meters.
Careful.
Craigslist could make a lot more money, especially in the short-term, with different design and monetization choices.
pl 'data.dat' u 1:3 w p pt 7 lc 3 tit 'Interesting measurements'
flows from my mind like breathing. I miss that brevity and speed so much when exploring datasets quickly in other languages....It's not nearly as maintainable as more-verbose and well-specified languages, but it's far more readable than regex :).
Edit to add: simply plotting a two-column data file in Gnuplot is as simple as:
pl 'data.dat'
the above plots the third column against the first column with blue circular dots and applies annotated text to the key/legend, as I prefer to do when exploring data for the first time...It's a clever plan, until the LLMs do some adversarial training....
I might also self-host if residential ISPs didn't treat home servers as an aberration.
"You should be willing to take either side of the bet that confidence interval implies." (paraphrasing; he says it better).
For a concrete example, with a 95% confidence interval, you should be as willing to accept the 19:1 odds that the true value is outside the interval as you are the 1:19 odds that the true value is inside the interval.
Aside from being generally correct, this approach is immediately actionable by making the meaning more visceral in discussions of uncertainty. Done right, it pushes you to assign uncertainties that are neither too conservative nor too optimistic.
If the notion of letting your reader take either side of the bet makes your stomach a little queasy, you're on the right track. The feeling will subside when you're pretty sure you got the errorbar right and your reasoning is documented and defensible.
Edit for OP's explicit question: One standard-deviation errorbars are 68% confidence intervals. Two standard deviations are 95% confidence intervals. (assuming you're a frequentist, of course)

The MO is the same as described in the article -- a well-crafted email with a link to a file in a respected cloud host.
Is there a centralized place (FBI ?) to report these attacks? The bad actors will be obvious in aggregate.
