When faced with an unsolvable problem, you are said to face a “Gordian knot,” a rope that is tied so intricately or tangled so completely that it is impossible to untie. If you dive a little deeper ...

What’s slice? It’s the umbrella term for two properties that this kind of mathematical knot can have. And a mathematical knot is a whole major field of study unto itself, inspired by regular knots ...

OVER the course of one week in 2018, Lisa Piccirillo cracked a mathematical problem that had gone unsolved for half a century. Posed by legendary mathematician John Conway in 1970, it concerns a ...

Conway’s knot, a famous mathematical problem, was a tricky one to untangle. Mathematicians have been arguing about how to solve it for more than 50 years—until 2018, when graduate student Lisa ...

For over 50 years, mathematicians have argued over the nature of a complex knot. The tangled problem, known as Conway’s knot, is so fabled among mathematicians that a depiction of the knot even graces ...

Fear not, fellow mathophobes: A new superheroine has arrived to rescue us all from innumeracy. Knot Man -- she’s “knot” a man -- and her canine companion, Knot Cat, are the stars of a comic book that ...

The first part of this article looked at trying to solve problems that appear to be impossible. The old saying “When all you have is a hammer everything starts to look like a nail” can be turned ...
