Dr. Jineon Baek's work reveals a new optimal sofa shape for maneuvering around corners, proving it's 2.2195 units wide. This had puzzled mathematicians for decades.
Baek's 100-page proof confirms that the maximum area of a sofa around a 90-degree corner is 2.2195 units, solving a problem first posed in 1966.
The solution not only aids in smaller living spaces but also conclusively lays to rest a 60-year-old mathematical problem, much admired by theorists.
Rather than a simple box, the ideal sofa shape resembles a telephone receiver, illustrating how complex real-world movement can be when solved mathematically.
