"Deterministic Nonperiodic Flow" is an academic paper Edward Norton Lorenz, published in the Journal of the Atmospheric Sciences.
The paper was highly influential on the emerging science of chaos theory.
Description
Lorenz states in that paper:
Two states differing by imperceptible amounts may eventually evolve into two considerably different states ... If, then, there is any error whatever in observing the present state—and in any real system such errors seem inevitable—an acceptable prediction of an instantaneous state in the distant future may well be impossible....In view of the inevitable inaccuracy and incompleteness of weather observations, precise very-long-range forecasting would seem to be nonexistent.
