This is fascinating, but wasn't it still a bit of a conjecture to assume the oil would spread to a minimum thickness of one molecule? Did he have any doubts, like that surface tension might keep it thicker? Or other clues hinting it was indeed a monolayer?
there has to be some missing information on how he found the area of water that fully consumed exactly that amount of oil as it simply doesn’t make sense without that. for instance one can spread a teaspoon of oil over 1, 2, n square meters and at some point the oil goes from m later thick to one to less than one.
This is one of those “so cool yet so silly” brainstorms that I’m grateful someone was audacious enough to entertain. I’m both relieved and saddened that it never came to fruition.
There’s a word, chindogu, to describe things that are less than useless. In some sense this project engendered more problems than it solved. Like so many other attractive brainstorms.

Most SO answers were non-answers or word salads. Thankfully one of you added an answer explaining that the cursor is already straight given that it must be visible from the graphics coordinate origin (upper left) and is 45 degrees wide.

I don't know about others, but I can't help but smile when I read the detailed series of events in aviation postmortems. To be able to zero in on what turned out to be a single faulty part and then trace the entire provenance and environment that led to that defective part entering service speaks to the robustness of the industry. I say that sincerely since mistakes are going to happen and in my view robustness has less to do with the number of mistakes but how one responds to them.
Being an SRE at a FAANG and generally spending a lot of my life dealing with reliability, I am consistently in awe of the aviation industry. I can only hope (and do my small contribution) that the software/tech industry can one day be an equal in this regard.
And finally, the biggest of kudos to the Kyra Dempsey the writer. What an approachable article despite being (necessarily) heavy on the engineering content.
Hard agree. Civil & mechanical engineering have a culture and history of blameless analysis of failure. Software engineering could learn from them.
See the excellent To Engineer is Human in just this topic of analyzed failures in civil engineering.

Doesn't RSA typically settle for numbers that are probably prime?
Technically I think so, so there’s a tiny bit of faith for RSA but absolutely none for primality in general https://en.wikipedia.org/wiki/AKS_primality_test

If you just make up a number claim it’s prime and nobody disputes it, it’s prime apparently. I don’t think it’s really possible to have a very large prime number, because unless someone has tried every factor it’s really not prime yet, honestly that explains a lot about the elusiveness of the concept.
> If you just make up a number claim it’s prime and nobody disputes it
You can test if a number is prime in polynomial time, much faster than a sieve. There’s no need to test every divisor to know whether a number is prime or not.
Algos like RSA generate large primes millions of times every day—-there’s nothing to take on faith.

> Jain, a copper-sulfide expert
I would have never known that people are actual experts in one material. This is impressive.
He's probably a *-sulfide or copper-* expert. Or maybe just a physical chemist that the press is ginning up. Actually, the latter. His page doesn't even mention copper or sulfide; and makes only one mention of conductors.
