Unsolvable Problems

Reader's Digest, Sept. 1990

During his first year of graduate study at the University of California at Berkeley, George B. Dantzig (later known as the father of linear programming) arrived late for a statistics class. He saw two problems on the blackboard. Assuming they were homework, he copied them and a few days later turned in his solutions. One Sunday morning six weeks afterward, the professor appeared at Dantzig's door, waving a manuscript. It turned out that the professor had merely written two examples of unsolvable problems on the blackboard. The manuscript was Dantzig's work readied for publication.
