A few highlights from reading All models are wrong: reflections on becoming a systems scientist; John D. Sterman. This is the paper form of a lecture held in 2002 by John D. Sterman, upon receiving the Jay Forrester award. What is System Dynamics? It can be seen through multiple lens, as: Science: the modeling process assumes hypothesizing, building a model, running an experiment - the simulation of the system through that model, and potentially invalidating the model.

I stumbled upon this paper while contemplating whether it’s possible (and valuable) to build a network representation of technology - eg. which tech requires which lower-level tech, which tech depends on which natural phenomena, how tech shifts over time, what feedback loops are present, … An ill-defined task that remains just a draft, a fun thought experiment; but let’s switch to the paper now.

The original article by Dijkstra can be found here (pdf). These notes are mainly to summarize my read of the article for future ref.
