Can Knot Be Unknotted

Did you know that there is an entire discipline out there dedicated to knots? The trefoil knot is one of the simplest ones to make. The difference between this knot and the one on your tennis shoes is that the trefoil knot cannot be unknotted. It’s a fundamental part of mathematical knot theory. If this is “knot” something you’re into, that’s okay, the trefoil knot is also kind of artsy and pretty as well. Buy it for yourself or give it as a gift. It makes an excellent present for knot mathematicians, knotty people, fans of knotty math, and those who do “knot” mind a good pun.
