One night, it was very late. An elderly couple walked into a hotel and they wanted a room. The waiter at the front desk replied: “I’m sorry, our hotel is full, and there is no room left.” Looking at the tired expression of the old man, the waiter said, “But, let me think about it…” < br> Now that the story is here, do you expect a continuation of mathematics below, still willing to get a literary ending? But no matter what, math and literature will break up here.
The mathematics story grows like this: this kind waiter started to deal with room questions for the old man: he wakes up the tenants in the hotel who have fallen asleep, and asks them to change the location: the guests in room 1 change to In Room 2, the guests in Room 2 changed to Room 3… and so on, until every tenant moved from his room to the next room. Then a miracle appeared: Room 1 was empty. The waiter happily arranged the elderly couple in. No rooms were added, no guests were lowered, and when the two old men arrived, all the rooms were full of guests-but only by deciding to let each guest move to the next room, the first room was vacated, this is why? / It turned out that the two old people went into the famous Hilbert Hotel in mathematics-it is considered a hotel with countless rooms. This story is told by the great mathematician David Hilbert,
He used this to elicit the mathematical view of “infinity”. This point of view is of primary importance to this discipline. It can be said that without it, it is difficult to imagine how mathematics will exist. As long as everyone who knows how to count knows, every integer has a successor to infinity (so in the Hilbert Hotel, there will be one behind every house until infinity)… Mathematics is a science about infinity.
Well, let’s go back to the place where the waiter said “Let me think about the method”. The literary story continues this way. This literary waiter deserves to be more humane and caring, and of course he can’t bear to let the elderly go out and find another place to stay. And in such a small city, I am afraid that other hotels are already fully booked. Wouldn’t this tired old man live on the street late at night? So the kind waiter led the old man to a room and said, “Maybe it is not the best, but now I have to do it.” The old man lived happily in front of a neat and clean room. Down.
The next day, when they came to the front desk to check out, the waiter said to them: “No, because I just lent you my room for one night-I wish you a happy journey!” in this way. The waiter didn’t sleep for the whole night, so he was on duty at the front desk overnight. The two old people were very moved. The old man said, “Boy, you are the best hotelier I have ever seen. You will be rewarded.” The waiter smiled and said it was nothing. He took the old man out of the house, turned around, and was busy with his own affairs, forgetting about it completely. Unexpectedly, one day, the waiter received a letter, Open it, there is a one-way ticket to New York with a short postscript, hire him to do another job. He flew to New York by plane, followed the route indicated in the letter to a location, and looked up, a magnificent hotel stood in front of him. It turned out that in the late night many months ago, he received a billionaire and his wife. The rich man bought a big hotel for the waiter, and he was convinced that he would run and maintain this big hotel. This is the legendary story of the first manager of the world-famous Hilton Hotel.
Things start from the wisdom mind of a compassionate and caring waiter: “Let me think about the method…” To enter the field of mathematics, what is needed must be rigorous logic, reasonable inference and precise To prove; came to the world of literature, relying on the beautiful human nature, moving plot and unexpected and happy ending. But you don’t find it: whether it’s literature or mathematics, the ending is amazing—love plus wisdom turned out to be a miracle.
