Laws of design and manufacturing. The maker of a product has to be greater, more complicated, than the product. The equipment needed to make a bolt and nut is always far more complex than the bolt and nut. The designer of a product will always be more intelligent than the product. The manufacturer will inevitably be far more intelligent than the production methods.

We find not only physical laws, but also health laws and moral laws.
