WebA knot is said to be chiral if it is not ambient isotopic to its mirror image. The words chiral and chirality come from physical chemistry and natural science. A knot that is equivalent to its mirror image is said to be achiral. (or amphicheiral in the speech of knot theorists). Many knots are achiral.
