In addition to epidemiology where people are "down" with an illness, critical infrastructure such as supply networks or transport networks can have some of their elements "down" due to a failure or even a deliberate, targeted attack. A powerful way study of the manner in which systems break down is through percolation models in which vertices and/or edges are iteratively and systematically removed (possibly at random, possibly preferentially to some attribute or calculated structural property) and the effects of such repeated removal.
This module will help you do the following:
We also revisit competencies developed in previous modules to actively build upon them (such a visualizing a simulated phenomenon over time and plotting a time series extracted from the simulation).
This time, we start by reading a news article.
Having now learnt the scale of the impact of the actions of an old lady, scour the internet for a similar example from another context: a minor-seeming disruption (something misplaced, something broken, something delayed, or something deliberately attacked) that caused an unexpectedly significant impact. In your response, please include a URL to a text or a video documenting the example you found along with a brief text (a paragraph or two at most) of your thoughts on why the example you found is similar to the warm-up story of the lady and the cable.
After this module, you should be familiar with the following concepts:
Remember that you can always look concepts up in the glossary. Should anything be missing or insufficient, please report it.
