There was silence in the classroom.

Looking at the two cubic sum representations that Ge Juntian wrote on the blackboard, the students were shocked beyond words: Indeed, if you want to say that 7, 13, and 19 are prime numbers, it is estimated that everyone can hold back if you give some time; but if you want to say that this kind of addition of cubes, let alone 60 seconds, you will never be able to think of this for 60 hours! But some people have thought of this peculiar representation method within 60 seconds.

Perhaps, this is the difference between ordinary people and geniuses, right?

Ge Juntian enjoyed this shock very much, and asked for a long time, "Do you have any objections?"

"Teacher, it is too cruel to decide life and death in one question, and it is inevitably unfair. Let's make another one!" a classmate begged.

"Yes, teacher, give us another chance!" the other students immediately begged.

Jiang Shuiyuan also said: "Teacher Ge, everyone is right, this question just now is too weird, and it is close to the game, it is difficult to see everyone's true level." Why don't you retest everyone in a different way?"

"Hmm...... Since you say so, then I'll give you another question and test you in a different way!" Ge Juntian pondered for a moment and finally agreed to everyone's request. However, anyone with a discerning eye can see that the reason why Ge Juntian agreed to re-issue the question was for the sake of Jiang Shuiyuan's request, otherwise he would not have bothered to care about the life and death of those "ordinary students", and immediately ordered: "You all turn around and turn your backs to the blackboard, and you are not allowed to look around until I tell you to turn around, otherwise you will be directly expelled from the Osaysha! ”

The senior who helped hurriedly agreed: "Okay!"

Although the twenty students didn't know which game Ge Juntian was going to play, they turned around honestly, and then they heard him "creaking" on the blackboard and writing non-stop, and it took two minutes before he put down the chalk and said, "OK, before you turn around, let me talk about the test rules." I've written 150 Arabic numerals on the board, and when you turn around, you'll have 2 minutes to memorize them, and then turn around and write them silently, and the test will see how many digits you can remember correctly. Any cheating in the process will be regarded as cheating in the exam, and the whole school will report it and record it in the file. Do you understand?"

"Understood!" replied the students in a haggled manner.

"Now that you've heard it, turn around! ”

It can be said that as long as you have read books and gone to school, you must know that there is a drudgery called "memorization", and the content of memorization is all-encompassing, including ancient texts, poems, new words, words, definitions, formulas, ages, meanings, etc., and so on, involving almost all the knowledge points of all subjects. As for how to remember, everyone also kills pigs and butts, and each has its own knife technique. But in general, I have more or less suffered from poor memory, and I have also dreamed countless times about when I will have the ability to remember.

Memory is congenitally inherited and acquired, but generally speaking, it is more congenitally inherited and more dominant, because most of their memories are commonly referred to as "photographic memory", that is, all information is converted into an image, like a camera taking a picture, "clicking" into the brain to freeze into an image, which can not only quickly remember a large amount of information in a short period of time, but also permanently retain it in the mind, use it at any time, and be able to reintegrate the information as needed. It can be called the pinnacle of human memory.

The acquired training is generally associative memory, which is to use interesting things to package and connect boring knowledge points to help memory. For example, the famous Newster College does this kind of thing, such as the English word sanguine, and he will make up this story for you: Chen Yuanyuan has just finished bathing in the hot springs, walks out with a "ruddy face" in a bath towel, and asks coquettishly, "san, gui, ne?" - and then you memorize the word firmly.

Ordinary people's memory is usually 80% rote memorization plus 20% associative memory, which has poor effect and is easy to forget. After a few days of retrospect, I can only remember the things I associate with and the vague framework, and I feel that "I have seen this sister before", but there is nothing I can do about memorizing it. Therefore, most people are afraid of memorization, and even leave a psychological shadow.

After Jiang Shuiyuan's genes have been optimized and adjusted by the bracelet, his memory is naturally a model of photographic memory, so when he made a bet with Mr. Han Xianru Han in the bookstore to endorse the book, an ancient text by Zhang Yuzhao is hundreds of words large, and he can memorize it in minutes, not to mention this Arabic letter?

His shocking move immediately caused an uproar in the audience: Can he recite them all? How is it possible, we haven't even memorized the first 20 lines? Is he a one-glance ten-line so he has the chance to win? Or is he deliberately putting on a show to put pressure on everyone?

Only Ge Juntian looked motionless and nodded secretly: Sure enough!

A strong memory is the best helper for scientists to engage in research. Like the great mathematician Euler, he can memorize all numbers within 100 to the power of 1 to 6 in one night, he can recite the ancient Roman poet Virgil's epic poem "The Aeneid" in its entirety, knowing that the whole poem is 12 volumes and 9896 lines, and he can also recite the content of the notes taken decades ago in full. Another example is the great mathematician Poincaré, who read books at an astonishing speed, and was able to memorize what he read quickly, accurately, and persistently, and even tell what was told in the pages and lines of the book!

After two minutes had passed, everyone turned around and began to write silently, and the water source of the river had been completed. Ge Juntian was about to go over to collect the scroll, and the senior brother next to him couldn't wait to run over and take the note from Jiang Shuiyuan: "Teacher Ge, let me see how this junior brother is silently writing!" Obviously, he was incredulous that Jiang Shuiyuan could write 150 numbers silently after a few glances, and wanted to check it himself.

Ge Juntian had seen a lot of unforgettable geniuses in Jingshi University, and he had long been shocked and insensitive, and said softly at this time: "Do you want to witness with your own eyes what it means to be unforgettable?"

The senior brother smiled awkwardly: "The so-called unforgettable, I don't know how many times I've heard it since I was a child, but I really haven't met anyone with this kind of superpower in my life." Now seeing that this junior brother is so magical, it is inevitable that I am a little happy to see the hunt, so I want to witness it in person, so that I can know how big the gap between myself and the genius is!"

"What a big gap? The gap between you and him is the distance between you and him, close at hand; as for the gap in the future, just like you and the sun, you can feel his brilliance and energy, but you can never catch up with him!" Ge Juntian is always so poisonous tongue, that senior brother's glass heart was instantly poked with a thousand holes, so he had to turn his head and carefully check the numbers on the note of Jiang Shuiyuan, so as to soothe his wounded heart.

A few minutes later, the senior brother couldn't help but exclaim, "It's not bad!

Ge Juntian took it for granted: "That's natural, otherwise how can you tell that 1729 is a taxi within a minute? Besides, if you don't have a full grasp, who will turn around and write silently after a few glances? Those who dare to do this are either geniuses or idiots, do you think Jiang Shuiyuan could be the latter?"

This kind of silent number test is absolutely simple, yes yes, no yes no, no blindness. And as time passes, the memories will only become more and more blurred, and the ones forgotten will become more and more, until finally the head becomes water on the left and flour on the right, and the slightest movement turns into a pulp. After only five or six minutes, the students began to hand in their papers one after another, and almost everyone was depressed, obviously not achieving satisfactory results.

According to the statistics of that senior brother, among the remaining nineteen people, they can generally only write about 40 numbers silently, with only a few in their early 30s and nearly 60 in the most. Among them, Zhang Jinmo made 47, which is considered to be above average, while Li Zhili made 51 silently, which was able to barely squeeze out the top five. But no matter what they look like, the gap between them and the water source of the river is like a world of earth!

Li Zhili and the others had nothing to say, but they still couldn't help but complain: "Teacher Ge, shouldn't the selection of the Olympiad focus on breadth and depth?

"It's not boring, it's about testing your abilities and potential, so as not to waste your time and mine!" Ge Juntian raised his head and said, "In my opinion, knowledge won't work, just spend some time learning to make up for it;

Li Zhili and others had no choice but to take advantage of the excitement and return in defeat.
