For what it's worth, the article posted here is not from 2024, but from this week: "Published : Jan. 4, 2026", and contains original reporting (quotes from the researcher). The mention of "Scientific American" in this article refers to something more recent: > US magazine Scientific American named the research by Baek Jin-eon among its top 10 mathematical breakthroughs of 2025 This is a reference presumably to https://www.scientificamerican.com/article/the-top-10-math-discoveries-of-2025/ https://www.scientificamerican.com/article/the-top-10-math-d... "The 10 Biggest Math Breakthroughs of 2025" (dated December 19, 2025). It's more recent than your link https://www.scientificamerican.com/article/mathematicians-solve-infamous-moving-sofa-problem/ https://www.scientificamerican.com/article/mathematicians-so... "Mathematicians Solve Infamous ‘Moving Sofa Problem’" (dated February 4, 2025). November 2024 is when he posted the preprint on the arXiv: https://arxiv.org/abs/2411.19826 https://arxiv.org/abs/2411.19826 "Optimality of Gerver's Sofa" (submitted on 29 Nov 2024). There has been other reporting since then, such as in Quanta Magazine: https://www.quantamagazine.org/the-largest-sofa-you-can-move-around-a-corner-20250214/ https://www.quantamagazine.org/the-largest-sofa-you-can-move... "The Largest Sofa You Can Move Around a Corner" (dated February 14, 2025). (Contains quotes from his adviser Michael Zieve, and from Gerver himself.) The paper is still under review at the Annals of Mathematics, so there will be likely be another round of reporting when it has finished peer review and is published.
