When the kindergartener identifies some classmates he expects to run to “his” piece of candy and others he expects will run to other pieces of candy, he is drawing a mental Voronoi tessellation map. In this game, when a kindergartener scans the room and identifies the piece of candy-his site-to which he is closest, Buceta says the child is modeling the situation with a Voronoi tessellation.

The nonoverlapping shapes with straight sides-polygons-depict the regions in which kids may stand at the start are the tessellation’s “cells.” Any kid inside an individual cell is closer to the candy (the site) in his or her cell than candies (sites) in any other cells.įigure 3. The black dots, which depict the scattered candies, are the “sites” of the tessellation. His kindergarten Voronoi tessellation example might be illustrated with the diagram in Figure 3. Once the candy lands, tell the kids to run to the candy that is closest to them,” said Buceta. Throw some candy in a kindergarten classroom where children are randomly playing. “Even kindergarteners know how to make Voronoi tessellations. Imagine the researchers’ surprise, however, when their microscopes revealed that scutoid-shaped epithelial cells were pervasive in the human body, news they published last July in Nature Communications. The model indicated that epithelial cells should take the form of an unusual and previously unknown shape they named the “scutoid.” Of course, epithelial cells in nature were under no obligation to observe the model, especially as the oddly-shaped, not-previously-observed scutoid seemed like an unlikely candidate.
