Motivation

Epidemiology is the important study of "why certain people are getting ill."

Background

John Snow memorial and pub.jpg

Imagine you are a physician in 1854 London in the midst of a cholera outbreak. Your theory that contaminated water is the cause meets resistance from the medical establishment which holds that it is spread via the air.

Imagine further that your friend Ada has left you access to computing.
