How an 87-Year-Old Math Problem Finally Fell in July 2026

Jacobian Conjecture for Baby

I built a step-by-step guide to the Jacobian Conjecture, a famous math problem that remained unsolved for 87 years before a surprising partial solution emerged in July 2026. Using simple animations and zero prior math knowledge, I explain how polynomial maps bend grids and why reversing them is so difficult. You can verify the final discovery yourself with basic arithmetic, exploring a story where every previous proof failed until now.
