Interestingly, similar random-walk models play an important role in studies of protein folding, which is Fink's main research interest. Meanwhile, the researchers have novel knots to show off in Cambridge University dining halls, where jacket and tie are still required. Designing tie knots by random walks. Fountain, H. 1999. Peterson, I. 1999.
Simulations nab protein-folding mistakes.
Seife, C. 1999. It's style, but knot as you know it. Waldman, P. 1999. Comments are welcome.
