Zeroization

In 1997, these authors produced a paper regardinga mathematical model of possible necktie knots used to tie a necktie, in essence creating a “Theory of Tie Knots.”  Naturally a book followed. They discovered 9 aesthetic necktie knots and presented their finding in Nature. I found the site looking for the Pratt Knot, a unique necktie knot that produces a thicker and more symmetric knot than the traditional four-in-hand.
