This mathematician proved the random walk theorem to clear his name as a lurker

Hungarian mathematician George Pólya repeatedly encountered the same student couple during solitary walks, appearing to lurk awkwardly. To clear his name, he mathematically proved that random walkers on a two-dimensional surface (like forest paths) are destined to cross paths repeatedly, while three-dimensional random walks allow escape. His theorem explains various real-world phenomena, from gambling bankruptcy to how molecules efficiently find cellular receptors by sliding along two-dimensional cell surfaces rather than wandering through three-dimensional space.
