But take it from Bill Menasco, a knot theorist of 35 years: This field of mathematics, rich in aesthetic beauty and intellectual challenges, and has applications. It involves the study of mathematical knots, which differ from real-world knots in that they have no ends. Each one is a string that crosses over itself a number of times, then reconnects with itself to form a closed loop. Today, we know the study of knots could have applications in surprising areas...
