This is for strictly mildly interesting material. If it's too interesting, it doesn't belong. If it's not interesting, it doesn't belong.

This is obviously an objective criteria, so the mods are always right. Or maybe mildly right? Ahh.. what do we know?

Just post some stuff and don't spam.

They counted the atoms?
Didn't they just took the mol mass and calculated it? (Not sure if mol mass is the right term... School chemistry is a long time ago...)
And I don't see how we even should be able to count them.
Would be really interested, if it happened that way, how they did it.

Ironic how the US wants to define the kilogram while the majority refuses to use it.
