Simple models which help us to investigate how epidemics grow and die out.
Which countries have the most naturally athletic populations?
Use the computer to model an epidemic. Try out public health policies to control the spread of the epidemic, to minimise the number of sick days and deaths.

straight railway line. A very fast bee starts off in front of the
first train and flies continuously back and forth between the. . . .
