A place for majestic STEMLORD peacocking, as well as memes about the realities of working in a lab.

This is a science community. We use the Dawkins definition of meme.
What about convection? There's been at least some mixing, right? So I'd guess the average age of a nucleus from the core (ignoring fusion) would indeed be less than from the surface, but I would think it's less difference (on average) than the raw math. If there's enough mixing it could be very little difference at all.
