Topology is the Silly Putty of mathematics.  Indeed, sometimes, topology is called “rubber-sheet geometry” because topologists study the properties of shapes that don’t change when an object is stretched or distorted. 331 more words

Introducing Cube Knots

This movie introduces cube knots—a new way to represent knots in 3-dimensional space. Cube knots are special because there are two Reidemeister-like moves that take any cube diagram representation of a knot to any other cube diagram representation of that knot. 83 more words

Mildly wild knots

The objects of study: these knots will
1. Have exactly one wild point.
2. Be the union of two tamely embedded arcs which are joined at their endpoints; needless to say one of these selected endpoints, say , will be the wild point. 968 more words
