The math world is losing its mind over the new solution to an Erdős problem. This is what AI found, how we missed it—and why it matters.

ChatGPT's breakthrough is not what it seems.

In mid-May, OpenAI announced that an internal AI model had disproved the Erdős unit distance conjecture, a famous problem in discrete geometry that had stumped human mathematicians for the last 80 ...

Physicist Richard Feynman turned a lunch dilemma into a math problem. Researchers finally cracked his notes and found people approximate his solution on their own.

The second batch of “First Proof” problems is meant to evaluate AI’s usefulness for research-level math. The best model got six or seven of the ten questions right.

The transcript explores Goldbach’s conjecture, the simple-looking claim that every even number greater than 2 can be written ...

We've all been there: staring at a math test with a problem that seems impossible to solve. What if finding the solution to a problem took almost a century? For mathematicians who dabble in Ramsey ...

The bat-and-ball problem is a famous math puzzle that more than half of people—even Harvard graduates—get wrong. It's ...
