Knot Theory
In topology, knot theory is about the study of knots and their properties, where a knot is defined as a closed, non-self-intersecting curve embedded in three-dimensional space. Wolfram|Alpha has the ability to recognize a knot with multiple representations and compute its properties or to compare multiple knots.
