A week ago there was a post interested in putting together an exhibit on "change." I lost track of who originally wanted to information. Phyllis K. Leffler and Joseph Brent, in their book PUBLIC AND ACADEMIC HISTORY: A PHILOSOPHY AND PARADIGM (Krieger Pub. Co, 1990) discusses chaos and change. For example, they say "During the last two decades a third and equal controversial wave of innovation in physics has arrived called "chaos." Unlike particle physics which is involved with "micro-events" far distant from human expereince, chaos is con- cerned with the "macro-event" scale of everyday human life. Its grand question is how, in a universe governed by the Second Law of Thermodynamics and moving relentlessly toward greater and greater disorder, does order arise? How does order come out of chaos?" They continued, "The idea underlying the image is that very small differences can rapidly create large-scale effects--that the physical world we recognize is characterized by extremely sensitive dependence on initial conditions, so that tiny changes in particular elements of a system could lead to large and incalculable changes in overall behavior." (pp. 72, 73). Does this help? john John Martinson [log in to unmask] College Place/Walla Walla, WA
