The "Butterfly Effect"
----------------------

The "butterfly effect" describes systems where a small change in the initial conditions can result in large differences in outcome at a later time. We examine this idea using the "Mayfly model" as an example, exploring circumstances in which nearby trajectories either converge or diverge.

Linear Least Squares
--------------------

The problem of finding a straight line which best fits a set of points arises naturally when we studied the "butterfly effect". We explore what a "good fit" means, and how to find one.
