4.7 Representing feedback through system dynamics diagrams
There is increasing recognition that the reductionist mindset that is currently dominating society, rooted in unlimited economic growth unperceptive to its social and environmental impact, cannot resolve the converging environmental, social and economic crises we now face. The primary aim of this unit is to encourage the shift away from reductionist and human centred thinking towards a holistic and ecological worldview.

5A Exploring positive and negative feedback through system dynamics modelling

Section 5 Activities

5A Exploring positive and negative feedback through system dynamics modelling

In this introductory activity the aim is to explore several simple system dynamics models as a means to visualise dynamic flows within a situation. What I love about system dynamics is that it uses a simple metaphor to capture how flows of energy, matter and information actually ‘work’ in reality. This metaphor is that of a bath with

Making Molecular Movies: 10,000,000,000,000 Frames per Second

Date of Lecture: Tuesday, December 12, 2006 at 7:30 PM

Movies have transformed our perception of the world. With slow motion photography, we can see a hummingbird flap its wings, and a bullet pierce an apple. The remarkably small and extremely fast molecular world that determines how your body functions cannot be captured with even the most sophisticated movie camera today. To see chemistry in real time requires a camera capable of seeing molecules that are one

Building Molecular Models of DNA, Protein, and Lipids
Molecular models of DNA, protein (alpha-helix and beta-pleated sheet), and lipids are built to scale. With a minimum of scientific jargon, these laboratory exercises effectively display the important aspects of three-dimensional shape and spatial orientation that are poorly presented in textbook illustrations and demonstrate how the shape of molecules and weak chemical associations like hydrogen bonds and hydrophobic/hydrophilic interactions combine to form the macromolecular associations fundam
