Lin Bin played table tennis from elementary school to university Chumin Basketball University Zhu Wenwu's basketball from middle school to the present Zhang Qian's 400-meter hurdles and volleyball from middle school to college Physical training does not increase your IQ, but it can develop your potential abilities. ——Zhu Wenwu "Use your left hand," the coach yelled frantically at him. Zhu Wenwu ran on the basketball court, and this was the first time he tried to dribble with his left hand. This happened when he was just in college, he couldn’t remember exactly what day it was, but he still remembered his clumsy look at that time: “That hand didn’t seem to be his own, it couldn’t be stretched out, it couldn’t be turned back , still can't catch the ball, and even the movement of the feet is distorted."

Like most of his classmates, Zhu Wenwu is not "left-handed", and the clumsiness of his left hand seems to be born.The most distinctive thing he inherited from his parents was his size.The father is 1.8 meters tall and the mother is 1.7 meters tall.When he entered college, he was 1.85 meters tall. "It's a pity that your boss doesn't play basketball." Everyone said to him. He liked playing basketball from elementary school to middle school. When he entered the college basketball team, his basic basketball skills were quite good. But after all, they are all amateurs. Now, the coach of the team came from a professional sports team, and he saw through his left hand problem at a glance:

"People play with two hands, but you only have one. Can you win?" The coach trained his left hand according to the training procedures of professional athletes.The first goal is to make the left hand as flexible, strong, delicate, and elastic as the right hand; the second goal is to make the two hands cooperate with each other, open left and right, and penetrate each other, just like one hand. The training is three times a week, two hours each time, very formal, and with such high expectations, unconsciously, the blood in the whole body is concentrated in the left hand. Even if you are not a physiologist, you can know that the left side of the human body is dominated by the right brain.Therefore, the process of training the left hand is also developing the right brain.

This state has continued for four years.Wenwu attended classes in the morning, practiced in the afternoon, and studied in the evening, so he described his life at that time as "classrooms, libraries, and courts, three points and one line."Sometimes he will represent the school to participate in competitions, and the best result he and his teammates have achieved is the champion of the Central South Division of the National University Competition. His left hand has really grown, and it's becoming more and more like a right hand. "Although the ability of the right hand has not reached 100%, but it has at least 70% to 80%." He estimated himself in this way.

This is to be expected.Unexpectedly, not only did the intense training not become a mental burden on him, but it made him feel energetic, and he no longer felt tired like he used to. Whether listening to lectures, reading books, or writing papers, after studying for a long time, there will always be a heavy and tired feeling in the mind, but this is all a thing of the past.Now, after a game of basketball, he feels relaxed physically and mentally. He came to believe that basketball was not only exercising his physical strength, but also his mental faculties. The students wondered why he was so energetic.He said: "The best way to release the fatigue of the brain is to exercise. Of course, you can listen to music or something, which also has the same effect. Then you come to study again, and you will feel that your energy has returned."

The energy in the human brain, much like the energy of a battery, has a regenerative quality.If you use it continuously, it may be exhausted in only 10 hours, but if you use two brains alternately, you may use it for 20 hours without feeling tired.This is why Zhu Wenwu always feels energetic. But what is even more amazing is the phrase "use your left hand" that the coach shouted at the beginning.Wenwu clearly feels that the process of becoming more flexible with the left hand is also a process of becoming more flexible with the right brain.So he began to call playing basketball an education for "developing the other half of the brain", and unintentionally uttered the so-called "left-hand theory":

When we play basketball, the feeling of the ball with the left hand and the right hand, as well as the proficiency in controlling the ball, must be the same.I used to use my right hand, but my left hand is very stupid. Now I want to make my left hand as smart as my right hand.Using my left hand all the time, I feel that I have trained my right brain to some extent, so I am smarter, and I feel more and more confident when I go back to the classroom and library.It turned out that when I was in middle school, my grades were not so good, maybe my intelligence was not so strong before.But after going to college, I feel that my intelligence has improved significantly, and my reading has become more and more smooth.Four years later, I started to study for graduate school, and I really felt omnipotent.I guess it has something to do with playing.Of course it doesn't mean you get smarter just by playing.There is not much difference in intelligence between people, and physical training cannot increase your IQ, but it can develop your potential ability.

"The sea is bigger than the mountains, the sky is bigger than the sea, what is bigger than the sky?" Anyone who has read this chapter knows the answer: "It's your brain." Let's hear what the folks at Microsoft Research Asia have to say about the brain. Zhang Yaqin: The more exercises you do, the more your mind is imprisoned I think the problem is to do a little, but absolutely not to do too much.If you do too many questions, your thinking will be imprisoned.Just use a few exercises to crystallize your concepts, and then forget about it.Learning should be about simplifying complex things, not the other way around.To understand the most fundamental definition is to simplify it.It was originally 3 main points, but you have done a lot of questions, and when you do the questions, you divide them into points, and you don’t know how many points are divided.This is the process of making the brain more complex and, in the end, confusing itself.I find that many students overlook the simplest things.In fact, we should do the simplest things well, and then do other things.

Zhang Hongjiang: 95 points and 85 points are both A Chinese children may be able to complete these courses with only 50% of the time and reach the current level, and the other 50% of the time is actually wasted.All kinds of tangible and intangible pressures require him to spend more time on study.He must master all the details. For example, he can master 95% of the details in 50% of the time, but he has to use the other 50% of the time to learn the last 5% of the details.This "last 5%" will never be used by 99% of people in their lifetime. In terms of "input-output ratio", this "5%" is the most uneconomical.But it is this "5%" that decides the outcome of the exam, and the difference between success and failure is often one point, or even 0.1 points.How many children fail the university entrance examination by one point!So kids have to spend a lot of time just to improve a point or two.In American schools, both 95 and 85 are A, and everyone thinks this is a level.American children don't have to work hard to earn those few points, so they have more time to think about other things.

Gao Jianfeng: There must be some illogical concepts I have listened to countless classes in college, and only one class left the deepest impression.It was a design class that time, and the teacher said to us: "Open up your mind." He encouraged us to use various methods to complete the design and achieve our own goals, that is, we are not allowed to copy ready-made things.When I was in middle school, I never heard the teacher talk about these things, so I found them fresh and interesting.My classmates and I were circulating a book at the time, and there was a story in it that just proved the teacher's thinking.The story begins with a question: Please measure the height of a house.This was originally a physics experiment, give a student a stone and a stopwatch, you can use the principle of free fall to measure the height of the house.All the students knew to do this, but only one student took a different approach. He went to the building administrator to ask the height of the building. "This is also a method. You need to have this kind of concept in doing things," the teacher said, "not only logical concepts, but also some illogical concepts." Wang Jian: Imagine the things in the sky Shen Xiangyang told me that day that deriving formulas now makes students stupid.I can't think of many things.I also have this feeling, for example, I can't think of things in the sky.How to turn things in heaven into things on earth is even more impossible to figure out.A person's imagination, creativity and education are related.Just letting students know "right and wrong" is not good education, at least not imaginative education, and students should learn to think about things in a state of "distinguishing right from wrong".What's the point if your idea is definitely right, no one disagrees, but it's mediocre?Why even think about it? Liu Ce: Are you the master of knowledge or the slave of knowledge? There is no knowledge that should not be learned.Knowledge is useful.The key depends on whether you are its slave or its master. If you are its slave, then these things are useless. It always restrains you and restricts your thinking.If you are its master, you can control it, use it, it will be useful.Whether you are a master or a slave, there is actually only one step: do you really use it.If you use it, you are its master immediately. If you just learn it and don't use it, you are its slave. This problem exists from elementary school to university.Everyone knows that if you only learn English without using it, memorizing words will be a burden. If you want to use it, it becomes a tool for you to communicate with others, and you will not feel that memorizing words is a burden. In fact, all knowledge is important. Is such that. 1. Most children who don't seem smart enough are not "brainless", but let their brains idle. 2. Adding all the courses and exams in the school together actually only develops one brain of the students, which leads to the fact that most students will only use one brain in the long years to come. 3. The growth of the brain is not the same thing as the accumulation of knowledge.Good students measured by accepted standards, such as test scores Excellent students do not necessarily have excellent thinking ability. 4. Almost all "E students" have a wide range of interests, and consciously or unconsciously train their brains in an all-round way. It is a pity that most people only use a small part of their intelligence in their lives.This is true even for a very good person. --Kai-fu Lee As we mentioned earlier, Kai-fu Lee's "philosophy of elites" has been a topic of conversation on university campuses for the past few years.to 20 In the spring of 2003, he talked about this matter again: "It is a pity that most people only use a small part of their wisdom in their lives. Even a very good person is the same." That night he sat In the western restaurant of Beijing Kerry Center, holding a glass of mineral water in his hand, he looked out the window thoughtfully. There is a secret in his statement that remains unrevealed.This is the "discount of intelligence". We already know an astonishing fact: the average person may only use 10%-15% of the brain in a lifetime, and more than 85% of the brain neurons are always in a state of sleep.We also mention the Japanese educator and psychologist Taisaku Inada, a man of lofty optimism about human intelligence.He believes that those who always say "I can't do it" are "making myself worse".These facts must be boon to those who always feel that they are not smart enough.The difference in human intelligence does not lie in the level of talent, but in the extent to which you can awaken your talent. After some careful research, Inada Taisaku proposed the concept of "brain index".This is similar to the concept of "IQ", so most Chinese are not unfamiliar with it.In fact, the topic of IQ is talked about by all teachers and parents.But educators have overlooked a problem: the IQ that most people have and the actual performance of the IQ are not consistent. If there is a concept that can illustrate this situation, it is the "practical IQ index".In the case of the same natural intelligence, the higher the "practical intelligence index", the smarter the person.This regularity leads to our first formula: Practical Intelligence Index = Innate IQ × ​​Brain Use Efficiency A person's ability to adapt and solve practical problems usually depends on practical intelligence rather than natural intelligence.For example, although a person has an IQ of 200, but only uses 50% of it, so his intelligence index can only be "100".Another person's IQ is only 150, but he uses 80% of it, so his intelligence index will reach "120", which is actually smarter than that naturally smart person.This is the great value of Inada Taisaku's so-called "brain index". But what is affecting people's "brain efficiency"?It's an attitude. "Brain efficiency" is not only based on intelligence, but also on attitude.In fact, when you grow up, your attitude is more important than your talent, and it is more important than your teacher's coercion, your parents' persuasion, your school's brand, grades, rankings and everything else.As long as you experience it with your heart, you will find that attitude is the most invaluable wealth and the greatest power in your learning process.It can lead you to the "E-student" ladder. In the case of equal "innate intelligence", the key to improving "practical intelligence" is to change your learning attitude.This law leads to our second formula: Brain usage efficiency = intelligence × attitude In fact, most people's intellectual problems are caused by psychological problems.These people have a brilliant brain, but just don't know how to use it. Once you have a high "brain efficiency", you will be pleasantly surprised to find that you are smarter than before, your teachers will start to praise your performance, your parents will start to believe in your ability, and you will have more time to let yourself go. Relax your brain, play your favorite games, or as Zhang Hongjiang said, go to "enlightenment".The students would also ask in amazement: "What's the matter with you? I didn't see how hard you worked, how did you surpass us?" You can answer like this: "Because I use 1% more brain cells than you do." Now let's discuss some of the most important factors to improve "brain efficiency".include: Brain Concentration Index. Open Brain Index. Brain Active Index. The reason why I spend less time in my studies than others is simply because I believe that it is better to study one hour of concentration than ten hours of absent-minded study. ——Zhang Yaqin Concentration, or full concentration, can obviously be the most direct factor in improving the efficiency of brain use.It is not It is just a habit of learning and an attitude of learning. Over time, it becomes a kind of ability.If you want to make yourself use your brain more effectively, then focus your energy on one thing to the greatest extent. We can use the "brain concentration index" to measure how much a person's ability to concentrate is.It consists of two factors: First, the length of concentration; Second, the depth of concentration. In general, the longer and deeper you concentrate, the higher your brain concentration index, so: Brain Concentration Index = Length of Concentration × Depth of Concentration Most of the children will encounter the following situations: their mind wanders unknowingly during class, they suddenly wake up, and quickly listen to what the teacher said, but after a short time, they lose their minds again.As a result, the memory in the classroom has become an intermittent and incoherent cartoon.In the evening, I was sitting at the desk under the urging of my parents, and I was doing my homework, but I suddenly remembered an event that happened during the day. , but after a while, my mind jumped to nowhere.They are always worried about a certain thing in their hearts: Are the test scores good?Will mom criticize?Want to buy something can you get it?When I was studying, I always thought about the time. When I looked up at my watch, I found that I had been sitting at the desk for less than an hour.And parents don't seem to care about these, as long as they see homework books piled up in front of their children, they are satisfied. In fact, the depth of concentration and the length of concentration are the key. This is what people often say, "Don't let your mind wander".But cultivating this ability has a deeper meaning: it is the real drive that allows you to develop wisdom, and it makes your wisdom seem superior to ordinary people. When we study the growth experience of "E students", there is always a strong feeling that their success is not because they are smarter than others, but because they can use their smartness more.In them, you can see what a person can achieve with the depth and length of concentration. "If you don't be disturbed for 6 hours a day and do it continuously for three, five, ten, or twenty years," Shen Xiangyang said, "then you can definitely do something amazing." Talk about your experience of concentrating.In fact, when Shen Xiangyang is concentrating on one thing, he can often stay up for days and nights.This is a habit he developed while studying at Carnegie Mellon University: "It was the hardest time I have ever been, but it was also very exciting. Every day is prime time from 9 pm to 3 am. I am studying. I am very envious of that time now." But when it comes to the highest record of "brain concentration index", it seems that Xu Fengxiong and Li Kaifu set it at Carnegie Mellon University.Xu Fengxiong has only done one thing for 12 consecutive years, and that is "Deep Blue", which has caused a sensation all over the world.Kai-fu Lee studied and worked 16 hours a day for 4 years. This is the "length of concentration"; he played 40,000 sets of "Othello" continuously and compared 2.4 million different moves. This is "the length of concentration". depth". We have already described how Zhang Yaqin "jumped around" during elementary and middle school, and spent 6 years to complete 12 years of courses, so he was regarded as a "child prodigy" by the people around him.But if you ask him to explain the mystery himself, you will get another answer. "I'm a little smart. But I don't think I can be so much better than others in terms of talent alone." He said, "The reason why I spend less time than others in the learning process may be because I The learning efficiency is quite high.” If there is one remarkable ability he developed in childhood, it was his ability to concentrate: I think I usually do everything I need to do when my mind is clearer.My brain is often in a divergent state.Sometimes studying for too long doesn't work well.I won't be so stupid, and still sit there and learn when I can't learn.I just concentrate on thinking and figure out all the problems within a few hours, and that's it.In fact, the longer you spend studying, the more tired you will be, and your energy will be scattered when you are tired.The mind has been distracted, and people are still sitting there, of course they are not efficient.Sometimes even though you haven't lost your mind, you can't get in. You just circle around the surface or periphery of the problem, which doesn't work either.Because the length and depth of your concentration are not enough, which is what people usually say is absent-minded. Yaqin's middle school and college classmates all said that he was not the kind of student who worked hard.When he was in college, the teacher still talked to him and asked him why he always didn't go to class. "Sometimes I forget, sometimes I like to sleep late in the morning." He explained a little embarrassedly.He is very indulgent in life, he does what he wants, and is playful and mischievous like all boys.The difference between him and them is not in this, but in his ability to concentrate energy quickly, and very focused. "Once I sit down to do something, I am very serious." He said, which can also be seen from his current work situation.For example, he plans to write a 20-page English article.Others will see him watching TV and surfing the Internet for a while, seemingly doing nothing. In fact, he has been thinking about how to write this article in his mind, so much that he doesn't even know what to see with his eyes.After thinking about it, he sat at the table, concentrated his energy, and spent one night, from beginning to end, in one go. "Instead of studying for ten hours absent-mindedly, it is better to concentrate on studying for one hour." He concluded, "Whether studying or doing things, the brain must be coherent, just like a laser. Go out, this lethality is the strongest."
