Tiling problems involving regular polygons

Dear Colleagues, Many tiling problems arise from looking at clusters of squares (polyominoes), clusters of equilateral triangles (polyiamonds) and clusters of regular hexagons (polyhexes). This site: http://www.squaring.net/ has a rich assortment of examples and enumerations including material about...

Pies and patterns

Dear Colleagues, The classification of symmetry patterns, including colored patterns, on a strip or in the Euclidean plane is one of geometry's many success stories. https://en.wikipedia.org/wiki/Frieze_group The fact that mathematics shows that all patterns of a particular type (rosettes, say) can ...

Women in mathematics

Dear Colleagues, Women show talent in mathematics at all ages but stereotypes about who has mathematical talent and accomplishment continue to persist. There is no doubt in my mind that the "system" still makes it hard for girls to realize that mathematics might be a good career choice for...

Mathematical insights into school choice

Dear Colleagues, Whatever the "true" motives may be in some cities implementing school choice programs there is no doubt that initial systems have been improved and understood better using mathematical tools. Two approaches that are being compared, contrasted, and tweaked are ideas related...

4-bar linkages

Dear Colleagues, If one makes a physical stick model of a planar quadrilateral with fixed length sides it will flex. When one studies the flexing of such geometric objects one is in the world of linkages. Linkages are often used to generate provable motions such as generating a straight line or more...
