Found an interesting view in Nature: Defining emergence in physics. It notes the disparity between the biological and physics views on the subject. It seems that a physics definition needs infinities to comply, according to them, whereas biology needs a very large but finite number. The authors propose this as a working physics definition: https://www.nature.com/articles/npjquantmats201624

Novel, in this context, means something completely different/new arises from a relationship that cannot be predicted from the parts... not to to do with chronological age.

The conditions necessary seem to be: irreducible, unpredictable and novel. It is a 'useful' descriptor for those phenomena that match that criteria, otherwise, what other word(s) shall we use?

I dunno, this concept is a work in progress for me. Just musing: could entropy have something to do with your examples not being emergent?

You can't reverse engineer an emergent phenomenon and, conversely, you can't predict the outcome of an emergent phenomenon from its component parts. Ultimately, emergence has a strong unpredictable element about it.

If you use photons to observe some particle, may they not change said particle's energy?

Or take a long walk on a short pier....

A spoonful of sugar.

I found this but way over my head. https://space.stackexchange.com/questions/284/why-should-the-james-webb-space-telescope-stay-in-the-unstable-l2 The maths seems to be here, as mentioned at the end of the first link: https://physics.stackexchange.com/questions/286642/why-are-the-lagrangian-points-l-1-l-2-l-3-unstable

@Janus might know.

I thought iOS users basically avoided adverts because they paid for much of the stuff... silly me. That's not advertising, that's spamming.

Perhaps the OP doesn't appreciate that the scientific community encourages an adversarial environment at research level. No one is going to give someone a leg-up to recognition, and apart from that, it is good for the pursuit of scientific fidelity.

uBlock Origin should sort it. They make it for different browsers.

I will invoke Newton: If I have seen further, it is by standing on the shoulders of giants. You can't create anything from a vacuum.

Could it be a response to the direction of the local current? How big that locale might be, I have no idea.

About 15 years ago, I heard Julian Byzantine's version on lute of this, and proclaimed to my guitar-playing friend that I wanted to play like that, and he responded with "Just buy the record"... way to suck my ego out.

@joigus Bach for lute on guitar:

"It's logical, Captain".

University is no longer a filter for the brightest in a subject. Opportunity should be equal to all, but ability isn't equally distributed. This is an example of how good intentions lead to mediocrity. Industry's job of finding the right candidates is made increasingly harder as time passes.

That figure was for bathing/showering water and transdermal absorption risk, as per OP. The OP's water is 1-2% of that figure, so it should be pretty safe for that use.

It seems up to 500ppb is safe.

This made me smile, from the leader of the China-leaning opposition party in Taiwan:
