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.

I think point two may be wrong. The strength of a shell should be proportional to its thickness, which would scale linearly with its size (assuming the shell got thicker in proportion to the size). There's definitely a point where a self supporting egg requires very thick shells like you said, but the scaling law you gave uses the wrong change.
