Mathematician Paul Erdős had no home, no job, and no hobbies. Instead, for 60 years he wandered the world, staying with each of hundreds of collaborators just long enough to finish a project, and then moving on. In this week’s episode of the Futility Closet podcast we’ll meet the “magician of Budapest,” whose restless brilliance made him the most prolific mathematician of the 20th century.
We’ll also ponder Japanese cannibalism in World War II and puzzle over a senseless stabbing.
