100 things: Dinosaurs in Crystal Palace Park







  1. Topology! If there are no free standing walls (ie they are all connected) then they are topologically equivalent to a single loop. So, keeping your left hand (or right) on the hedge, you will always end up going through all the corridors of a single entrance maze, which means you will go through the centre at some point. Doesnt work if there is a piece of hedge that is not connected to any other part.

    It is roughly the same argument that tells you a teacup is the same as a doughnut, but different to a teapot.

  2. And yes, it would be me who not only knew that, but was pathetically keen to show you that I knew. :)
