A young college student was working hard in an upper-level math course, for fear that he would be unable to pass. On the night before the final, he studied so long that he overslept the morning of the test. When he ran into the classroom several minutes late, he found three equations written on the blackboard.
The first two went rather easily, but the third one seemed impossible. He worked frantically on it until — just ten minutes short of the deadline — he found a method that worked, and he finished the problems just as time was called.
The student turned in his test paper and left.
That evening he received a phone call from his professor. I must not have gotten the problems right after all. I discussed it with the class before starting the test. And you just solved it! One day InGeorge Bernard Dantzig, a doctoral candidate at the University of California, Berkeley, arrived late for a graduate-level statistics class and found two problems written on the board.
The equations Dantzig tackled are more accurately described not as unsolvable problems, but rather as unproven statistical theorems for which he worked out proofs. George Dantzig recounted his feat in a interview for the College Mathematics Journal: On the blackboard there were two problems that I assumed had been assigned for homework.
I copied them down. A few days later I apologized to Neyman for taking so long to do the homework — the problems seemed to be a little harder than usual. I asked him if he still wanted it.
He told me to throw it on his desk. I did so reluctantly because his desk was covered with such a heap of papers that I feared my homework would be lost there forever. He rushed in with papers in hand, all excited: Read it so I can send it out right away for publication.
To make a long story short, the problems on the blackboard that I had solved thinking they were homework were in fact two famous unsolved problems in statistics. That was the first inkling I had that there was anything special about them. A year later, when I began to worry about a thesis topic, Neyman just shrugged and told me to wrap the two problems in a binder and he would accept them as my thesis.
The second of the two problems, however, was not published until after World War II.
It happened this way. Around I received a letter from Abraham Wald enclosing the final galley proofs of a paper of his about to go to press in the Annals of Mathematical Statistics.
I wrote back suggesting we publish jointly. He simply inserted my name as coauthor into the galley proof. Dantzig also explained how his story passed into the realm of urban legendry: The other day, as I was taking an early morning walk, I was hailed by Don Knuth as he rode by on his bicycle.
He is a colleague at Stanford. Do you know that you are an influence on Christians of middle America? He told me his ideas about thinking positively, and I told him my story about the homework problems and my thesis. A few months later I received a letter from him asking permission to include my story in a book he was writing on the power of positive thinking.
The moral of his sermon was this: If I had known that the problem were not homework but were in fact two famous unsolved problems in statistics, I probably would not have thought positively, would have become discouraged, and would never have solved them.
He later worked for the Air Force, took a position with the RAND Corporation as a research mathematician inbecame professor of operations research at Berkeley inand joined the faculty of Stanford University inwhere he taught and published as a professor of operations research until the s.
George Dantzig passed away at his Stanford home at age 90 on 13 May.Free math lessons and math homework help from basic math to algebra, geometry and beyond.
Students, teachers, parents, and everyone can find solutions to their math problems instantly. Half of the math problems I have had, do not work with their program; 3) they say to email them the questions and they will provide the solutions, but it can take up to 24 hours, and sometimes that is too long to wait for an answer.
