Exploring the Mathematics of Cancer

By: James P. Dildine, with advice and calculations from Howard A. Silver.

This page is meant to provide an interactive sketch that you can use to explore the ratio of perimeter^2/a for the three figures shown.

Notice the crablike figure and the changes that are made in the ratio as you drag certain points around on the figure.

Notice also the regularity of the circle and the square like sketch. Can you modify the crab-like figure to have a more stable ratio of r?
