…s could be found close together in the limit set. This behavior was called “sensitivity to initial conditions” by David Ruelle (1978; Ruelle and Takens, 19771). It is noteworthy, however, that over a range of values of the parameters, the overall pattern of the orbits of the Lore...

…ge onto an attractor which is neither a fixed point nor a limit cycle, thus the origin of the name “strange attractor” (Ruelle and Takens, 1971). It was James Yorke that first named these dynamics “chaos” (Li and Yorke, 1975). The necessarily statistical properties of the chaotic...

…otide dynamics was available. It is perhaps unfortunate that for finite length real data, “house keeping requirements” (Ruelle, 1990; Rapp, 1993;1994) and “warnings on the label” with various random sequence, random phase controls (“surrogate data”) have become so intimidating to...
