 According to Moulines, in Balzer and Moulines (1996, 12–13), the specific notions of the Sneedean program are the following. We illustrate these notions by simplified examples, inspired by Balzer et al. (1987), which are based on a system of \(N\) classical point particles coupled by springs satisfying Hooke’s law. For a recent introduction into the basic concepts see also H. Andreas and F. Zenker (2014).
