This paper reasons about the need to seek for particular kinds of mode
ls of computation that imply stronger computability than the classical
models. A possible such model, constituting a chaotic dynamical syste
m, is presented. This system, which we term as the analog shift map, w
hen viewed as a computational model has super-Turing power and is equi
valent to neural networks and the class of analog machines. This map m
ay be appropriate to describe idealized physical phenomena.
