Polynomials aren’t just exercises in abstraction. They’re good at illuminating structure in surprising places.

The “sensitivity” conjecture stumped many top computer scientists, yet the new proof is so simple that one researcher summed it up in a single tweet.

In just three pages, a Russian mathematician has presented a better way to color certain types of networks than many experts thought possible.

A graduate student has helped illuminate a long-suspected connection between addition and multiplication.

People have known about magnets since ancient times, but the physics of ferromagnetism remains a mystery. Now a familiar puzzle is getting physicists closer to the answer.

A science fiction novelist and an internet commenter made breakthroughs on a longstanding problem about the number of ways you can arrange a set of items. What did they discover?

A new proof from the Australian science fiction writer Greg Egan and a 2011 proof anonymously posted online are now being hailed as significant advances on a puzzle mathematicians have been studying for at least 25 years.

How many colors do you need to color an infinite plane so that no points 1 unit apart are the same color?
