HP's Chinese Parents

[-] million candy strands, white as snow and shaped like a waterfall, fluttered down from between the slender fingers, and were cut cleanly by sharp scissors. The length of them was neatly curled up in Nick's palm It became a dragon whisker crisp without filling.

Nick put this exquisite little thing on a beautiful porcelain plate and handed it to the person behind him: "Here, the afternoon tea I promised."

The voice with a smile woke up Alan Turing, who was inexplicably suffocated, and he realized that he had been holding his breath since he didn't know when.He coughed twice in embarrassment, reached out to take the plate, and admitted defeat uncomfortably: "Well, Mr. Riddle, I admit that you won, although I know that powers of 2 are nothing special, but you stretched the candy His whimsical ideas really amazed me. So, you can call me my name if you want."

In order to deliberately make things difficult for Nick, Allen set up two contradictory traps in the request before. Usually, no matter how small the size of the items that are convenient for counting and calculation is, they will definitely not be able to fit in the hand under the huge quantity.However, the number of things whose volume meets the requirements can usually only be estimated, and cannot meet the "accurate" requirement he put forward.Even if someone finds out that it is 2 to the 20th power, it is well known that the maximum number of folds of paper is difficult to exceed 9, and to get 1048576, the number of folds of paper must reach at least 20.

Unexpectedly, Nick would use such a clever method, and Allen admitted that he had changed his mind about him.

"My pleasure, Alan. Call me Nick if you like."

Nick put on an indifferent smile on his face, but secretly felt ashamed in his heart. It was a fluke that he realized that the garbled seven-digit number was 2 to the 20th power so quickly after Allen made the request.

He just thinks that a number like Alan Turing who is full of love for mathematics should be meaningful even if he said it casually. When approaching such a huge number, he instinctively thought of the number of powers, and then naturally I thought of stretched noodles and dragon beard crisps.

他一开始并不确定这是2的次幂数，只是尝试把这个巨大的数字拆分成几个2的次幂数之和，毕竟这样比较容易操作。再考虑到1048576是首位为1，末尾为6的7位数，所以他自然而然地用他记得的最大的2的次幂数——2的十次幂——1024做平方。

This mental calculation is actually very simple, as long as the junior high school mathematics simplifies the formula into

(1000+24)(1000+24)=1000000+48000+24*24，

then use

24 * 24

=24*25-24

= 600-24

= 576

Solve the only difficulty in it and you will get the answer quickly.

It's really a good luck that it just happened to happen, otherwise Nick, who used mathematics purely as a tool, would not be able to guarantee the correctness of his mental calculations, and ninety-nine out of ten would pretend to fail.

This also made him realize the difference between himself and a genius more clearly. The problem he struggled to solve at the same level may be seen by the other party at a glance.

He thought of an anecdote about von Neumann.

A riddle was once posed to von Neumann:

Two trains a mile apart were traveling toward each other at 1 mph when a fly was flying towards the other train at 30 mph.When it flies to another train it quickly turns back.Find out how far the fly has traveled until the two trains meet.

When people see this problem, they will first ask the problem of the encounter between the fly and a train, then get the positions of the two trains after the encounter, and then do the problem of the encounter between the fly and another train, and so on, it becomes an infinite series summation The problem.In Mathematical Olympiad, there is a separate chapter for it, which is called the problem of turning parts into wholes. Jumping out of the surface, according to the hidden condition that the train encounter time is equal to the flight time of the fly, the answer can be obtained by multiplying the encounter time by the fly speed.

But almost as soon as the man finished reading the question, von Neumann answered directly: one mile.

The man praised: "Most mathematicians have not thought of the trick of multiplying the total flight time of flies by their speed, but use infinite series to spend a lot of time to solve."

Unexpectedly, von Neumann was also puzzled: "What technique? I also use infinite series."

Nick lamented that all computing skills would be eclipsed in front of these giants whose computing power is comparable to computers, because they can directly and violently solve any complex computing problem.When Nick first learned binary, he used his fingers to recite from 2, 4, 8... to 512, 1024. Now that he thinks about it, if he were Alan Turing, he would probably wonder why this thing still needs to be recited. Bar.

The two guys with complicated moods went to the living room with piles of snacks made of scraps, and found that John was bending over and talking to Tom.Going up to ask, it turned out that Tom was caught by John when he was holding Nick and the map he drew and hung them all over the house.

"I remember that Alan liked to draw maps when he was a child!" John looked at the hand-painted version of the world map with a look of nostalgia, "At that time, other children were playing ball outside, so he just nestled in the room and drew his own map book .”

Allen put down the snack, looked at the map thoughtfully, and asked Tom, "Did you draw this?"

Tom eagerly wanted to get his precious map back from the hands of the two strangers. He fixed his eyes on the map and replied casually: "Nick drew the outline, and I filled in the colors."

John's eyes lit up when he heard it, and he praised himself for his good vision: "I'm sure what I said before is right, you guys can chat like this, you should keep in touch more!"

Nick was flattered to hear that.

Allen looked at Nick with puzzled eyes for a while, and let him go until he looked at Nick inexplicably, and muttered: "Interesting."

Nick:? ? ?

===============

In the following days, Nick, who found that his sweetheart became his neighbor, did not become happy. While tidying up the house, he was immersed in the anxiety of gain and loss.In the dream, he returned to modern times and posted on the Internet:

After successfully pretending to be coercive, the boss seems to appreciate me very much. How can I prevent the boss from finding out that I am a parallel importer?

The highest praise below is:

Thank you for the invitation, the answer is very simple, just stop appearing in front of the boss from now on.

When he wanted to reason with this man angrily, the doorbell rang, and he opened the door, and Alan Turing, whom he was thinking of, stood outside the door: "Mr. Riddle, you let me down so much, you know nothing about mathematics." know."

Nick: ...

He woke up straight away.

The author has something to say: Alas, is it too boring to do too much math?Fewer and fewer comments...

Recently, I suddenly fell in love with Doomsday Literature, and opened a Doomsday Literature.The protagonist is a real boss who has cheats but fights against the five scum.
