Platonic solids in the next dimension
Frank Sottile
    While we are all familiar with regular polygons (equilateral triangles, squares, ...), and many of us know about the Platonic, or regular solids (tetrahedron, cube, octahedron,....), few are familiar with their analogs in dimensions four and higher. Of course, this is because we are not equipped to perceive four-dimensional space directly.
    Nevertheless, the description of the regular solids in all dimensions has been known for a long time. The purpose of my talk will be to introduce you to these objects, with an emphasis on how to think about them. This presentation will be spiced up with some models of four-dimensional regular solids, some of which you can build yourself.
