In assembling the pattern, it is necessary from time to time, to examine the state of the pattern many atoms away, if one is to be sure of not making a serious error when putting the pieces together.

Penrose's statement about quasicrystal assembly, used as evidence that non-local action is required in natural morphogenesis

Non-Local Action in Assembly
supports
Penrose's claim that assembling quasicrystals requires examining the state of the pattern many atoms away, implying that global structure guides local assembly

Claims (1)

claim

Assembly of quasicrystals requires examining the state of the pattern many atoms away, meaning global structure must guide local assembly — a clear case of non-local action.
supports
Penrose's claim, endorsed by Alexander, that quasicrystals demonstrate non-local causation in morphogenesis
