Refection of Doolittle's article

The first idea I got from here, is the linking between geometry with gardening.  I think it might be interesting to do. A teacher can use the foods in class to introduce the concepts, properties of the different shapes, and students can cut and chop to make specific shapes they learn.
The second idea is the grid and mapping. In China, Beijing, Xi'an and Nanjing, the formal national capital cities most are grid in triangle blocks. other cities around the river will have some parallel streets along the river bank. This phenomenon matches Doolittle's theory- failure of the grid.
