So what is represented by the repetition count? Is it an intended weighing to compensate for something else or what?

The important part in the original post is that we're giving the two helium atom a choice of two _same for both_ states. If one of them is here~ish and the other is 1km~ish away, they are nearly perfectly distinguishable (which does not mean that they aren't identical).

Coming back to "atoms in the body are replaced", this is most obviously effectful for carbon: C14 is unstable, so as long as that replacement is going on you have around the same ratio of C12 to C14 as the environment around you. Once you die, as long as you don't decompose (and thus stop exchanging carbon with the environment), the amount of C14 will go down as it decays, which is what makes carbon dating possible.

Actually, how well known is Verne's Mysterious Island?

@mcc @johncarlosbaez @akkana

When I tried to make sense of reasonable doses (fwiw I take 1mg/day in a supplement and my milk, yoghurt, and cheese replacements are fortified to levels iirc similar to the originals) I've encountered descriptions of reasons for low levels. There is apparently an efficient food->blood transport that's broken in some people (in whom this is the reason for the low level in blood). There's also a ~100x times less efficient transport by, afair, just straight up diffusion, so one approach (but the least well studied iiuc) for those people is to give them absurdly massive doses orally (the better studied approach to treating those people is IM injections).

Related: "Are you sure you want to cancel" dialog, where in some localizations the "yes, cancel" and "no, cancel cancelling" buttons end up with the _same_ label, because the translator never saw them side by side (or maybe even the same translator didn't translate both, as the generic "cancel" one was likely translated way earlier).

@mcc @johncarlosbaez @akkana

YMMV, but I never found it hard to get supplements of B12 only in Poland or Switzerland (I mostly eat vegan, so I need to take them, eat things fortified with B12, or both), but had to specifically ask (and specifically ask for a nontiny dose).

Also, the aged username and password part and the not-so-aged port part.

TIL that work hardening during machining may have nothing to do with increased temperature (at least according to implications of wikipedia).

Ah, right, I confused the direction of electronegativity (I think; you chelate lots of other metals using sodium or potassium salts after all).

Ok, so this should be making the solution basic, so could be easy to disprove.

@_thegeoff @mcc

But what would happen with the sodium?

@_thegeoff @mcc

I remember getting something I believed to be water soluble (maybe I was very silly and was fooled by a very fine suspension?) by leaving a nail in a jar of brine on a radiator for a week. I guess I'll need to reproduce that and make sure (a) I remember everything correctly (b) it's actually a solution.

@_thegeoff @mcc

Hm, I must be wrong. Sodium is much more electronegative than iron, so it's extremely unlikely anything like that would happen (based on my directional intuitions only; I'm very bad at chemistry).

So what the heck is that soluble thing that you get when rusting iron in saltwater?

@_thegeoff @mcc

IIRC when you rust iron in saltwater you get partially water-soluble rust (in contrast to rusting it in freshwater). I always assumed that the soluble part is iron chloride (which is pretty well soluble and supposedly has a matching color of solution), and that you'd still get that in absence of dissolved oxygen. But maybe I'm wrong~~

@mcc

Even rusting that doesn't involve oxygen?
