"Tying Physical Theory into Stable Knots," by Ivars Peterson. *ScienceNews*, 3 May 1997, page 270.

This brief article describes recent work linking knot theory, which is a branchof mathematics, to field theory, which is used to describe many physicalphenomena. Researchers have for the first time found knot-like structuresarising in solutions to certain equations in field theory. This work hasconnections to string theory and liquid crystals.
