We've neglected the world of geometry for far too long and so this week we thought it time we brought you the latest developments in shapes. Most of the tracks on the show are about specific polygons and, because we like to order the world around us, the tracks about polygons are played with an increasing number of sides. We leave it to you, dear listener, to predict the upper limit to which we soar. WARNING: An assertion in the first part of this show could bring the world of mathematics crashing to the ground.
