Knot theory

Knot theory is a branch of topology inspired by observations, as the name suggests, of knots. But progress in the field does not depend exclusively on experiments with twine. Knot theory concerns itself with abstract properties of theoretical knots — the spatial arrangements that in principle could be assumed by a loop of string.
