The announcement has created a lot of buzz, as one would expect. But there’s an aspect of OpenAI’s work that I haven’t seen anyone talk about: they posted a Lean 4 formal proof at the same time as […]\n\nThe post", "url": "https://wpnews.pro/news/the-part-of-navier-stokes-no-one-is-talking-about", "canonical_source": "https://www.johndcook.com/blog/2026/09/09/formal-method-revolution/", "published_at": "2026-09-09 12:43:36+00:00", "updated_at": "2026-09-09 13:11:20.718554+00:00", "lang": "en", "topics": ["ai-research", "ai-products"], "entities": ["OpenAI", "Lean 4"], "alternates": {"html": "https://wpnews.pro/news/the-part-of-navier-stokes-no-one-is-talking-about", "markdown": "https://wpnews.pro/news/the-part-of-navier-stokes-no-one-is-talking-about.md", "text": "https://wpnews.pro/news/the-part-of-navier-stokes-no-one-is-talking-about.txt", "jsonld": "https://wpnews.pro/news/the-part-of-navier-stokes-no-one-is-talking-about.jsonld"}}
