Catalan’s Constant: Inside OpenAI’s New Proof and Why Irrationality Was So Hard
A number can be easy to calculate and maddeningly difficult to understand. Catalan’s constant fits that description perfectly. Its defining series is simple enough to write on a napkin, yet deciding whether the result is a fraction resisted generations of mathematical work. OpenAI’s manuscript dated September 24, 2026, claims a proof of its irrationality. The … Read more
