Fractal equilibrium count
- How many times can one fold a piece of paper - 7, 8,9, maybe 13 - but not more (??)
- The food-chain: How many links between the top and the bottom of the food-chain. With whales and plankton, not many, but I have been told the max is 6. After that there is nothing to be gained, and what is comes at too higher cost.
