This is the first time hearing the term "kilobucks". I love it (and am stealing it for future conversations).

In French project management parlance, we use k€ all the time.

How do you pronounce that? Kilo-euro or K-euro?

Whenever I hear it, it is pronounced "keuro" (k-uh-RO). And "meuro" (m-uh-RO) for millions that are Mega-euros (M€).

I guess the french equivalent of kilobucks would be briques (bricks)

If you were born before WWII, yes.

(The only person I know that still used «briques» in these decades were my grand parents born in the 1920th)

I am mildly concerned about the "normalised deviance" of the siloxanes in the water. It's probably an acceptable amount and it's probably fine, but "eh, its only a bit worse than expected, what's the worst that could happen" is what lost 2 space shuttles

I still use « briques », typically « 10 briques » instead of « 100 k ». I think there is some poetry in sticking to the old obsolete term.

kha-euh-ro - including the "euh" impronounceable by non-French.

An interesting substory that is simultaneously reminiscent of the Fogbank story and how Hayek's "curious task" is much more broadly applicable: There is a good cautionary tale here from the Space Shuttle era. That vehicle had heat resistant tiles that had to be attached to the aluminum belly of the orbiter. A special cloth had been certified for wiping the aluminum clean before applying the primer that securely bonde…

The "curious task" full reference from Hayek:

“The curious task of economics is to demonstrate to men how little they really know about what they imagine they can design.”

Intended as a warning against command economies and centralized structures more generally, because the information-processing requirements are much larger than one might expect. But of course there are few things more central-planning than a space programme.

Indeed. "Grease peaks" we called them, they were always there in basically all NMR or MS spectra I took as an organic chemist. Like PFAS or microplastics, you just can't get rid of them.

I bet some of these modern environmental contaminants is causing the increasing age cohort cancer rates.

Look up the biocompatibility and safety profiles of siloxanes

Siloxanes contaminate everything. We routinely see them on various surfaces when doing X-ray photoelectron spectroscopy.

Apparently we also put polydimethylsiloxane in deep frying oil. Wonder what that does to our innards.

For antifoaming?

While this is all new to me, surprises like this are a big part of why I now think we should aim for the Moon first, and only consider Mars when the moon bases are nice and boring.

If there was any "we don't even know if this is an emergency" surprise interaction along these lines, a 3-day emergency resupply mission (or evacuation) is much, much easier than a 6-9 month trip when the planets align.
