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.

You can get that blocker for edge

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:

I was going to make a thread called "You couldn't make it up", with this as the subject. They contain thorium oxide, an alpha emitter. They are supposed to ionize the air but alphas don't do that.

Yes, I think the draconian measures needed to start there. Maybe they'll do that next time.

I think the way some in the US talk about freedom is way overrated, It's not to be at any cost.

There can be no freedom without civic responsibility. This needs to start with embedding it into schoolchildren from the beginning of their education.

Thanks. I remember that from someone here some years ago. Pretty spot-on I thought.
