Scaling exponents:
- 0.9 for companies
- 0.85 for infrastructure of cities
- 0.75 for organisms
Why there are physical limits to size of things
- Area (and strength) increases with with the square of lengths.
- Volume (and weight) increases with the cube of lengths.
As length increases, strength can't keep up with weight, therefore a strcture collapses under the weight of itself.
- Relative strength systematically increases as size decreases
