Cheng Xu: Dear students, distinguished parents [microblogging], guests, good morning!

I have a lot of experience and feelings in the past 20 years, every year to give undergraduate and graduate students a big class. In the past, I read graduate [microblogging] students, but also will be on the 100 people, 300 people of the big class, I rarely take this kind of class at Peking University, I used to feel pressured, and now I really have to reflect on it. We all know how we understand liberal arts education, the word sounds relatively new, now it is the West has a lot of teachers and students to communicate and promote their interest. As soon as we checked the thesaurus we found that in 1941, the Republic of China translated this into Boya College, I do not know if there is any relationship with Peking University, also known as Yanjing University at that time, which has the Weiming Lake Boya Tower. We have to have our own unique personality and our own unique pursuit. Boya supported us to have our own independent power of thought. We especially advocate a small class, a kind of real exploration, equality.

My topic today is the love of Yanyuan, unrepentant youth. To talk about the Department of Computer Science and so on I still have the confidence to speak to the parents, to the future of the young people who will live here for four years, I know what any examination of the university means to a family. This is something that I have thought about and experienced, and it should be meaningful to everyone. I'll say it in these 8 words.

Why did you choose BYU? I want to pass on the differences I perceive in life for you to choose from, whether this is what you want, there are many reasons for choosing the place you want to fit in. there was a blog post on the Peking University admissions website in 2004 called 10 Reasons I chose Peking University. I want to say that Peking University has a lot of special things, there are a lot of people on the Internet will say that Peking University has a school motto, in fact, today in the internal Peking University, we still argue, Peking University motto in the end what, today there is not an answer to tell you, but I can tell you about our traditions.

In 1898, the darkness of our politics, the lack of people's livelihood, and more importantly, the country and the nation in the very important turning point of life and death. It is also this country and nation, hope that we can through a series of improvements, new practices can make us change. Yanjing University Hall, at that time, it is not only to introduce the Western system, it also has a major function, equivalent to the Ministry of Education to coordinate the modern education in China how to do, Peking University faculty and students and the destiny of the country tightly together, you can not find another university and the destiny of the country and the nation within such a long period of time so tightly together. Our tradition can be summarized as patriotism, progress, democracy, and science. If we have to choose between the eight words, the first two words cannot be chosen, that is, patriotism. What should we do about patriotism? Does it need to change? Change may be good or bad, but I hope that our change will lead to progress for the country and the nation. We cannot simply criticize, but we have to raise critical suggestions with a constructive mind, or make suggestions in the form of criticism. From the founding of the Republic of China in 1911 to the renaming of Peking University in 1912, the first president was Mr. Cai Yuanpei. Let us take out a passage with a history of hundreds of years. Peking University is supposed to encompass the great canons, to enlist all schools of thought, to be free in thought, and to be inclusive. It is often said that Peking University is free, and Peking University hopes that any flower can bloom to its fullest. Our faculty representative, Mr. Lu Xun, what is the spirit of Peking University? First, Peking University is always in the vanguard of a new and improved movement to bring China to a better and upward path. Secondly, Peking University has always fought against the forces of darkness.

The educator is not for yesterday, nor for today, but for tomorrow. At the end of the last century, UNESCO had a series of studies on how education should really go in the 21st century, which resulted in four important aspects, the first of which is to learn to seek knowledge. One of the most basic things to do in university education is to show you how to gain understanding, and this is something that is not simply taught in terms of counting, or 1+2=3, but in terms of a lot of applications, and a lot of different aspects, and it teaches you the way to learn. By learning in this way you are trained in a very good system, so that you have the confidence to learn for life, you can learn in an effective way as soon as possible, which is very important. Is that enough? Not enough. But also to learn to do, really know how to solve real problems, really know how to apply what you learn. Is this enough? Not enough. Then there is learning to **** with life, between human beings, between human beings and society, and between human beings and nature, and more importantly, learning the social role you want to be. It should have to be to promote the holistic development of each individual, physically, mentally, intellectually, interactively, with a sense of personal responsibility, leadership qualities, and spiritual values in more ways than one. Moral and physical fitness is not simply a matter of us wanting to pursue excellence, wanting to pursue a complete person, all aspects should be considered from a comprehensive perspective.

There are three kinds of ability to do things. 30 years ago to learn mathematics, science and chemistry, all over the world are not afraid. Now it does not work, can not use a single successful model to set of, the modern concept of education is to have respect, choice is so. The old 16-word policy, strengthen the foundation, dilute the specialization, according to the individual, streaming training, this is 20, 30 years ago, the education policy, is for our country in the construction of new China, the university is to learn the former Soviet Union is too divided into fine cases and said, but that time has a very important historical significance. Now called to strengthen the foundation, promote cross, respect choice, excellence in education [microblogging], and the original 16 words have a new change, before we have to go through the teacher, through the leadership, in the education system, the transformation of the concept of education, into today's real students as the object and center of teaching. Let the students participate in the whole teaching. Doing is a particularly respected thing, specifically to you, why the college entrance examination [microblogging] [microblogging] will have a lot of bad places, you can pass a number of several exams, can show that your ability to do things strong? Really useful? So we said, if the history of a lot of things are not put in it, a lot of people say this is useless. We are still a developing country, and many of our systems still need to be improved, and many of our mechanisms still have a lot of potential for further improvement and development. At this time may not simply abandon the college entrance examination on the line thing, we can not find what is fairer than the college entrance examination, can let everyone really feel, no matter whether your family is a high-ranking official or poor, or your family rich or my family is poor is very fair fact.

Beijing University we now also need to reflect the stage that we choose the people we need, there are more people who need Peking University, people who choose to join us. In terms of doing things, not much to say, we all do a math problem, so many of us in teaching, rarely ask, why do we do this math problem. Over the years I've done a lot of high school publicity around the country, and I often ask, why do you want to learn logarithms? The best answer I've heard is from Nankai Middle School in Chongqing, if you don't know why you're learning it, you probably won't get anywhere. The college entrance examination, the teacher let me do the problem so. We all say that learning math, a very important way of thinking, is that I want to transform the space in the middle of the more difficult problem to another space into a simple problem, if we quickly with positive and negative transformations to, the space complex problem solved. 17th century, when people first put forward the logarithm is to solve multiplication, division. Many of today's students ask are you right? Isn't it harder just to log and antilog? In fact, students who went to high school 30 years ago, this generation used logarithmic and antilogarithmic tables, look up tables, today students don't look up tables, it's all about calculators. 30 years ago everyone had a calculator. It won't work if you simply just tell him what logarithm means and don't use scientific reasoning to solve the problem.

The ability to navigate things is usually the ability to tell you one thing and give it to your buddies, to really see the strengths of others, to really let the collective **** with the completion of this character, the most efficient. We need a combination of competencies, but then you don't have that kind of chest, and the humanistic chest is important. You can't just harness it, you have to plan things. No one knows what kind of cell phone we will use tomorrow, and what kind of cell phone we will have in 2 years, do you know? I don't know, why do we need to make it like this, to meet everyone's needs, which is more important is to plan things. Speaking of a few simple examples, an old secretary of Peking University, how do you understand the high and distant? My old leader told me that it takes a real state of mind to climb to the top of the mountain and see beyond the horizon, and that it is not possible to see beyond the horizon once you have climbed to the top of the mountain. If we have climbed to the top of Mount Tai with great difficulty and we are concerned about the flowers and plants under our feet, how can you have the feeling of having a panoramic view of the mountains. These things are not simply a matter of teaching a certain skill, a specific small method. Ascension is precisely the relationship between intelligence and wisdom, China said smart, you can not play small smart, we usually say small smart, big wisdom, which is to harness their own smart smart smart. Know where you should go to put your intelligence to use, and where you should not count.

Look at another sailplane versus an aircraft carrier. Many of the parents and schoolchildren who have come here today must be excellent in a single way, and the family thinks my child is the best. We usually go to the beach, we are most envious of seeing people who like to windsurf, surf, how free, how relaxed. As we all know, life is a long road, though life is short, and the bumps encountered in the middle of it are no less than crossing the Pacific Ocean, can a windsurfer cross it? I don't know if it has ever been done in history? At least I don't know. How do you do it? It takes a team, really melting yourself into a collective, melting yourself into a community, to gain real strength. Teamwork is very crucial. How do you really work with more people, and how do you look at other people with appreciation?

I would like to talk about faith, as long as the faith does not slip, there are always more ways than difficulties, this is the mentality, you are trying to do things well mentality. Followed by the middle of university education, living environment, around these people, in fact I think and teach you the knowledge point is more important. Why did Mencius' mother choose her neighbors. Whether we are outstanding or not, it is to keep our individuality and to be able to pursue outstanding. Not only simple class, you go to class, grab the table, grab the chair partner, you have to know that they have power in them, very strong spirit. It's really about moving your brain without hurting your brain, and hard work without suffering your heart. This brings us to a revelation about bicycling. It snows heavily in September and October in the Northeast, so you have to be careful and cautious on your bicycle. There's a guy bobbing around on his bike in the distance, and you think he's going to fall, and if you're noble enough, you'll go over and help. Usually we are not noble enough in our hearts, the first thing we think is how we fell, the second thing we think is whether we hurt ourselves or not, he fell, if you don't push your car, you will surely fall too. Always look away, the road is naturally straight. The second point in the foreseeable danger, life do not fall the same heel.

Take a look at the data from Peking University again, after the reform and opening up, the mainland to the United States of America, the number of students studying [microblogging], in the United States to obtain the membership of the National Academy of Sciences, from 2004-2013, there are about 10, which is 10, there are four undergraduate master's degree students at Peking University, of which three are our undergraduates, and one master's degree, undergraduate in the China Agricultural University [microblogging] [microblogging], from the roots of the Agricultural University's is also 52 years of faculty restructuring from Peking University in the past. 2 of 2013 are alumni of Peking University. Why Peking University students go abroad to develop scientific research this item has achieved such good results, but also make us very proud. There are quite a few schools in this, undergraduate is not as outstanding as today, if it is the fathers and mothers must tell their children, 20, 30 years ago, the entire mainland a year enrollment of college students, including the third less than 300,000 people. In those days, the distance between universities and colleges was far from being as pronounced as the score gap is today.

What President Wang said on March 27 this year, "Some Peking University graduates are not engaged in their majors, but they can still make a career, which is the uniqueness and charm of Peking University, and Peking University is unrepeatable."

The world's best-known psychologist and founder of the behaviorist school, "What does it mean to educate? If when we forget everything we have learned, what is left at the end is the essence of education." Those of you who have read books will wonder which question in college you really remember. Do you remember the chemical equations? These things are not the most important. It's precisely the body of knowledge that allows me to learn it again, and I'm very confident in how to learn it faster. That kind of stuff is the most important. This is what we call asking people to be a more well-rounded person. Since the founding of Yuanpei College 20 years ago, we have general education, and we must choose a certain number of courses that increase your humanistic bosom, and humanistic students must choose courses in science and technology that increase your scientific consciousness. This is our basic requirement. Peking University said we certainly respect your choice, but more need to you these two in the middle, to arts and science must be balanced.

Like Wang Yazhang, he said I'm going to do something for Peking University, and I hope I can pick out the people that Peking University needs the most, the ones that are critical to Peking University's research and future. We know that one of the richest people in high-tech companies, Robin Li in Peking University for undergraduate study, reading is not computer information, called the Department of Information Management, in his time, the main do research and study is oriented to the library. But he was at that time in addition to their own disciplines, in addition to learning well, very much aspire to the computer, so he listened to a lot of computer classes, so to the United States to study [microblogging] [microblogging], see the huge potential of the Internet search, with a lot of colleagues began to talk, which has a very important patents, that is, before the study of library materials classification, the algorithms proposed, and got a great deal of success. His business is in the southwest corner of the west door of the small resource hotel a few people began to start business.

Peking University has too many things to say to you, we especially emphasize that if you especially want to focus on a specialty, there is no doubt that we can provide you with want to be the best in this specialty, but you have to know that this is not really you like, or really have the potential to do deep, this is a completely academic type of talent. There are also people who say, I want to put this learning into practice, something that can really be used, and feel accomplished and happy through the things that other people use the ideas that I have designed, and we have applied talents as well. There are also composite talents, and we provide an outlet for that as well.

Information and human civilization are inseparable, but why do people call the information society, insects are not called the information society, today we talk about information and the ancients talk about information is not exactly the same, early can say that the beacon transmission is called information. In the 1940s there are two important inventions, February 14, 1946 at the University of Pennsylvania, digital electronic computers, also 46 years to do out of the integrated tube, 57 years to do the succession of circuits, which at least four people won the Nobel Prize for science. Moore's law, 1951, there is the first commercial computer. 1996 to spend 1 yuan to buy the computer news. In 1951 it would have cost over 100 million. The computer is the least value-retaining things, from 96 years to today, still maintains the price-performance ratio of 1,000 times every 10 years, the future to go up to what time, today you see is not the result. In the past period of time, we just put a lot of computational things, inside the information society, with computation as the core and communication as the link, connecting the physical world with the new world. You can see, here today, if it is a parent comes, the child is outside did not come, you can use the cell phone to send him all kinds of short messages, 4G cell phone you can put the things that I speak, real-time to do visual intercom, these are what is the meaning of it? That is, we make the physical world immediately, there is a copy of the physical world is not felt, but really can be applied to the space of the net electricity. We especially want to be like the Monkey King, shorten the distance, the second shorten the time, but if the computer is done well, the subsequent digitization is done well, you want to go back to the work, you can really do, the simplest is that if the home installed video monitors, your home appeared what should not have happened, you can rewind to that time. The School of Information Technology includes a variety of computer situations, as well as the Department of Microelectronics, communications, radio and electronic information, including the future of technology quantum technology and so on. There is also the Department of Intelligent Science. Today's computer information, has been integrated and information technology, it is called information technology.

One is not felt today, the subsequent must have the big enough computer in support of you, voice computing. How big? A computer that is so big that a computer is more than twice as big as this house that you see today. Today our dependence on electricity and running water is the most basic of urban civilizations. If your house went a month without running water and electricity, I don't know how many people could survive if you were still not allowed to leave the house. But if you think about this 100 years ago, we wonder, then the dependence on material things, but today's information-dependent society, just like for electricity and tap water, later on the calculation is like a water meter, whether it's sent from the Three Gorges or Henan, you don't need to know. Tap water is the same, whether Nongfushanquan is produced in Zhejiang or Jilin, you do not need to see. The same goes for computing. Put a CPU small computer and pressure sensors all in 1 cubic millimeter inside, now we can do, follow up inside the camera can be made, this is not a myth, is a human can do things. We can see there's tons of ubiquitous computing, and in the future you don't have to worry about losing your keys. I don't necessarily have an identity, but I'm someone who has an ID. The ID card has a chip, and there's a CPU in the middle of the chip, it's just not being used right now. And so on, we can feel the future of information, we can relate to a lot of places from the human, in addition to the earth's mind, there is a can make information in a wide range of processing, so a new net electricity space.

The development of the science of computers from human life again. For thousands of years, quite a lot of human beings have relied on the science of exploring the world, which is really scientific experiments, repeating scientific experiments, and that's how it's been for thousands of years. It is only in recent centuries that modeling has been used, and models and generalizations have been widely used to make theories. From the 1940s, when digital electronics was invented it began to be simulated with computers, and now physics, math, chemistry, biology, materials, medicine, and a lot of other things have gone completely to scientific computation as the third article of exploring the unknown world of mankind. In the last ten years and out of the fourth, represented by big data, data exploration, we will integrate the integration of the three previous integration, scientific experiments, theoretical derivation and simulation methods, integrated these to explore the human world as the fourth road. Computers are also taking an increasingly important role in the status of science.

Not to say that we should not learn it later, you may really need to have an understanding of it, not only nature, is the humanities as well, the international business has a lot of universities began to really in a wide range of exploration of how to integrate the computer and the humanities intersection, so that the cultivation of education, especially in the undergraduate.

Before all the disciplines and technologies, from science to technology to industry, there is no one like the information technology industry, talking about the index, the first to put 1 grain of rice, the second to put 2 grains of rice, each put a multiply by 2, means that each increase in the number of the front of all the numbers add up to a smaller than the back. Sustainable growth is critical. There's a lot of new time coming to happen here, making it hard to know what the future looks like.

Everyone says there are GOOGLE glasses now, whether you remember me today or not, after all, so many people look at me alone, it's hard for me to remember someone. Today and you look at a side, the next time I look at you, the glasses will tell me in which place I have seen you. Many people go abroad, the only obstacle our language. The words you don't understand immediately become your language, and all these things are the charm of information, all the charm of information science. You can imagine how many sciences information science has to go and merge with in order to produce more important innovations.

From another point of view, it is very critical, from the Stone Age to the Iron Age to today's integrated circuits, integrated circuits use silicon, the size of a fingernail can put 11 transistors.

This picture shows the first classroom after the Wenchuan earthquake, Beichuan Middle School, where we made all the computers, from the CPU to the software. It's not just for the press, but these kids feel the world's concern for them and hope through their computers. Chairman Wu Bangguo went to the site at that time, and he was also smiling, and the Premier wrote about how difficult it is to prosper. Chinese education can feel the future in the children.

Many people ask you undergraduate also not read in Peking University, you and Peking University what relationship? I am a drop of water in the Lake of the Unknown, even a drop of water, but also to reflect the light of the sun, this drop of water only placed in the Lake of the Unknown not to dry up, the Lake of the Unknown connected to the five lakes and the four corners of the world. I really hope that people who have a destiny with Peking University will come to Peking University.
