Eric the mathematician amazes us once again by creating a geometric tessellation in the shape of his head! It's not magic ... it's mathematical! The pedagogical side: This segment presents complex patterns or tessellations (forms that are repeated many times and which are perfectly intertwined with one another), as well as geometric transformation (eg a slip, a reflection or a rotation ) to visually introduce the geometric notions of pattern placement, spatial relationship and the integration of mathematics into the visual arts.
