Mathematician Cracks the Enigmatic Moving Sofa Problem
Originally Published 1 year ago — by ScienceAlert

Mathematician Jineon Baek from Yonsei University has potentially solved the long-standing 'moving sofa problem,' which seeks to determine the largest two-dimensional shape that can navigate an L-shaped corner in a corridor. Baek's 100-page proof confirms that the maximum area for such a sofa is 2.2195 units, aligning with Joseph Gerver's 1992 proposal. This solution, yet to be peer-reviewed, could be the definitive answer to this geometric puzzle, aiding in better furniture design decisions.
