This DVD combines a lecture with an informal interview to bring out the fascination of the subject of knot polynomials as well as a personal view of the field from one of its leaders. In the interview portion of the tape, Birman discusses her role in the discovery of the celebrated Jones polynomial, how she got started in knot theory, and some of the changes she has seen in the field. Birman's lecture, widely praised at the 1992 Joint Mathematics Meetings in Baltimore as one of the best introductions to the subject, balances the intuition of pictures with the rigor of technical details. Because she starts with the basic definition of a knot and moves up to the developments involving Vassiliev invariants, this lecture will interest undergraduates and researchers alike.
