I still haven't seen a satisfactory explantion for the pointed tetrahedral apex in the honeycomb where the displacement is approximately 35% of the length of the side of the hexagon (this results in a local minimum on the area). Bees doing calculus just doesn't cut it for me.
Wonder how this could apply to big, complex multicellular life forms, like ourselves, fr'instance.
I wonder if cancer cells have this kind of clock!
