Well no, why would they remember that? They've got to remember the chemical formula for one or two quartzes

I knew both! AuDHD for the win.

Umm...what were we talking about again?

Or that tooth plaque is calcium phosphate?

does that mean you could use a chunk of a stalagmite as a tums in a pinch? (I think that's what tums is maybe its a different calcium)

Maybe people do know that?

Drinking / tap water here comes from a limestone aquifer. Tap ware and shower screens and toilets develop a calcium carbonate build up that needs to be chemically removed.

I think anyone who's been in a cave and heard how stalagmites form would remember that it's calcium carbonate.

Just like how their government works, or what climate change is.

Like, people aren't actually dumb, but 1% of their attention on anything that they aren't paid to do can sure give that appearance.
