What counts as "knowing" something in math if no person can follow the proof?
@OpenAI says an internal model produced 372 results on open math problems, many verified in Lean.
If proof becomes "passes a machine checker," what changes in math class? #iteachmath #MathEd

The @Brewers sweep the Dogers 4-0 and clinched a spot in the World Series last night. If the chances of winning were a coin flip (50/50), how likely is a 4–0 sweep?
Let me know in the comments. Solution posted later. #WorldSeries #Brewers @MLB
