MAA Found Math for the Week of October 31, 2011
MAA Found Math: Tom Leathrum (editor of Loci) carved "quasipumpkin" for MAA's Mathematical Pumpkin challenge.
Leathrum writes, "'quasipumpkin' includes a segment of the 2-rhombus Penrose tiling P3. I couldn't go much further around the pumpkin than what is shown in the pictures, because the curvature of the pumpkin introduces distortions into the Penrose tiling. The pumpkin itself is rather small, less than 1 foot (30cm) in diameter. Perhaps I could have fit more of the tiling onto a larger pumpkin..." Read more about 'quasipumpkin' with references here.
