George Dantzig: Homework / Domáca úloha


“I was a mathematics graduate student at the University of California, Berkeley. Arriving late to class as usual, I quickly copied the two math problems from the blackboard, assuming they were the homework assignment. When I sat down to work on them that evening, I found them to be the most difficult problems my professor had ever assigned. Night after night I worked, trying first to solve one then the other with no success. But I kept at it.

“Several days later, I made a breakthrough and solved both problems. I took the homework to class the next day. The professor told me to leave it on his desk. It was piled so high with papers that I was concerned my homework would get lost in the clutter. Reluctantly, I dropped it off and went on my way.

“Six weeks later, on a Sunday morning, I was awakened by a pounding on the door. I was startled to see it was my professor. ‘George! George! he was shouting, ‘You solved them!’

” ‘Yes, of course,’ I said. ‘Wasn’t I supposed to?’ The professor explained that the two problems on the blackboard were not homework; they were two famous outstanding problems that leading mathematicians so far had not been able to solve. He could hardly believe that in only a few days I had solved them both.

“If someone had told me that they were famous unsolved problems, I probably wouldn’t have even tried to solve them. It goes to show the power of positive thinking.”

George Dantzig is a professor of Operations Research and Computer Science at Stanford University.

aerodynamically the bumblebee shouldn’t be able to fly.
But the bumblebee doesn’t know that, so it flies anyway.”
