This cite was not in the comments section moron. Here is the link to the C.V. of the poster who had stated the obvious concept, that positive feedback is an exponential formula. By obvious, I mean if you attended a scientific meeting and said that positive feedback was not an exponential formula, you would be like someone who attended a mechanics meeting and stated that the carburettor should be attached to the top of the radiator. The concept is that obvious. http://csiweb2.cite-sciences.fr/derosnay/english/cv.html Here is from economist Brad deLong. Note he adds the comment about positive feedback being exponential growth as an afterthought. That is: just a reminder of an obvious concept that anyone knowlegable about the math would already be aware of. excerpt Over time, (e(b1-b2)t) grows without bound: positive feedback produces rapid exponential growth, after all. http://www.j-bradford-delong.net/movable_type/2003_archives/001185.html Third hit brings up a management consultant, stating the obvious. excerpt The results of simulations of positive and negative feedback are shown in the figures. For positive feedback we see exponential growth. http://www.exponentialimprovement.com/cms/WhyExpImp.shtml Negative feedback can stop the positive feedback from being exponential, so that the overall effect is not exponential. For example, the exponential formula of compound interest can be alleviated by bankruptcies, which inject interest-free/debt-free money into the economy (albeit in an unpleasant way).
