Offside is a violation rule in football match, which means that the receiver stands closer to the goal than the second-to-last defender at the moment when the attacker passes the ball and tries to prepare for the attack.
The formulation of offside rules is a perfection of the rules in the development of football matches. In the football match in the 19th century, there is often a picture that the attacking players are all concentrated in the opponent’s restricted area or even in front of the goal, ready to start shooting after receiving the ball. Due to the high concentration of personnel, there is little wonderful cooperation in the football match, and the play is simple and boring.
In order to change this situation, mobilize the players to run actively, and increase the competitiveness and interest of the game, in 1870, the British Football Association formulated the rule of offside. At that time, it was stipulated that there must be at least three defensive players between the catcher and the baseline, otherwise they would be sentenced to offside.
In the following years, the rules of offside were constantly changed and improved. For example, in 1880, the rules of catching goal kick and corner kick were added, and in 1907, the rules of catching the ball in one’s own half were added.
In 1925, international football association board revised the offside rule again, changing the limit of three players to two. This change has greatly promoted the attack and development of football matches.
From the definition of offside, it is not illegal for a player to be offside, but if he is offside and participates in the attack, he will be sentenced to offside violation. Therefore, in the game, some players will choose to stand still after knowing that they are offside, indicating that they are not involved in the attack.
Of course, participating in the attack is not limited to catching the ball. Players who are offside will also be sentenced to offside if they have the following behaviors:
1. Get or touch the ball after passing or touching the ball by the team members, thus interfering with the game.
2. Interfering with the opposing team members, including: ① obviously obstructing the line of sight of the opposing team members, so as to hinder the opposing team members from handling the ball or affect their ability to handle the ball; (2) compete with the opposing team for the ball; (3) there is an obvious attempt to touch the incoming ball close to his position, and this move affects the opposing team members; (4) make obvious actions that affect the ability of the opposing players to handle the ball.
3. Touch the ball after the following situations, so as to gain benefits or interfere with the opposing players: ① The ball bounces or refracts from the goalposts, beams and opposing players; (2) The ball comes from any opposing player who intentionally saves the ball.
It must be noted that the following situations will not be judged offside:
1. Corner kick;
2. Directly connect to goal kick;
3. Throw a foul ball.
Football is a sport in which the feet are the mainstay, the ball is controlled and dominated, and two teams attack and defend each other on the same rectangular court according to certain rules. Football is called "the first sport in the world" because of its strong antagonism, changeable tactics and large number of participants.
The player of football is Cuju in ancient China, which spread to Europe through Arabs, developed into modern football in Britain and spread all over the world. At the second modern Olympic Games held in 1900, football was officially listed as a competition, while the first World Cup was held in Uruguay in 1930. After decades of development, it became the highest honor in football and the most famous and influential football event.
The highest organization of football is the International Football Federation, which was founded in 1904 and headquartered in Zurich, Switzerland. The highest organization in China is the Chinese Football Association, which was established in Beijing on January 3rd, 1955.
The above is an introduction about football.

Human intelligence begins with language, and artificial intelligence begins with words. The greatest wisdom of human beings is the invention of education, and intelligence is rooted in education. Education has changed the development of human intelligence from "present continuous tense" to "present perfect tense". Matter and energy in intelligent machines are real things in the physical level, while structure and time are abstract thinking in the cognitive level. Structure and time are parasitic on matter and energy, forming a hard structure; The information in the machine is a large number of soft structures, which shows that the spiritual world can be parasitic on hard structures or other soft structures, with virtual reality, virtual reality and self-reuse, and there is always at least the next time period, so that the machine can "think" again, and its order shows the ability to maintain its own thinking and produce orderly events. Human thinking and machine thinking are isomorphic in mathematics and homologous in physics, supported by energy and dependent on negative entropy for a living. The birth of intelligent machines has impacted all aspects and elements of education, from teaching "books" to teaching "learning" and then further to teaching "education", from how to possess knowledge, to how to use knowledge and then to how to create knowledge. The essence of education in the intelligent age is to cultivate the imagination and creativity of thinking. The core of human thinking is abstraction, association and interaction, and so is the machine. Machines use soft structures to extend and expand people’s thinking. More importantly, machines can think violently, and people and machines can learn from each other and complement each other, forming iterative intelligence. The problem of educational reform in the intelligent age has been urgently placed in front of all mankind. Reading changes one person and education changes all mankind.Let’s meet this learning revolution!
In recent years, many educators have embraced artificial intelligence with great enthusiasm and discussed how artificial intelligence can empower education, especially using the achievements of machine learning to improve teaching methods, improve learning efficiency and reduce teachers’ burden. As a long-term worker in the field of artificial intelligence, the author wants to look at education from another angle, from the angle of artificial intelligence, and explain why machines can think and how to think, and how to promote education to keep pace with the times after human beings have intelligent machines (people).
1. Natural evolution has laid the biological foundation of education.
Natural evolution does not care too much about human beings, so how did human beings suddenly stand in the global hegemony in such a short period of time [1]? Look at how osprey catches fish, how bees build nests, how ants dig holes, how spiders weave webs, how tigers move and catch, and how chimpanzees create and use tools. Their intelligence is amazing to human beings. Compared with other biological intelligence, the human eye can only see visible light, but the human ear can’t hear ultrasonic waves. The ability of pets to identify their owners is also better than that of their owners. The essence of natural evolution is the diversity of species, and the evolutionary law of survival of the fittest does not care too much about human beings. So, what is special about human evolution?
After millions of years, the uniqueness of human evolution is reflected in three aspects: first, in the process of human evolution from early reptiles to upright apes, human beings liberated their hands, learned to make tools and work, and compared with other creatures, human beings have a pair of dexterous hands; Secondly, human vocal cord pronunciation and cochlear hearing are exquisite and magical, and their language ability is strong. They can also distinguish who is speaking with complex and exquisite pronunciation. Third, human beings have a complex brain, first of all, the brain stem, which is the core of the whole body regulation and conscious. By the time it evolved into mammals, higher organisms had emotions. On the basis of the conscious and emotional areas, the outer cortex of the brain exploded, with a volume of about 300cm3 and a surface area of 2,200-2,850 cm2, containing nearly 100 billion active nerve cells and 900 billion colloidal cells, which became a unique human cognitive trait, as shown in Figure 1. Natural evolution has given the biological basis of education. There are only 3 billion base pairs in human genes, and genes determine the connection rules or patterns of neurons, but do not specify the connection strength of neurons. However, there are about 86 billion neurons in the human brain, with an average of about 1,000 connections per neuron, so genes cannot completely specify the connection mode and strength of each neuron, which leaves room for remodeling the day after tomorrow. Education, especially early education, shapes a person’s cognition. Compared with other creatures, natural selection, natural selection and survival of the fittest [2] have formed a complex and exquisite human brain, at the cost of taking a long time to evolve.It is to replace the generations of life and death for thousands of years, to preserve any individual who has favorable variation, and to destroy any individual who has any inappropriate deviation in structure.
Figure 1 Biological basis of education: three special features of human evolution
2. Human intelligence begins with language, and words extend outside the body to become artificial intelligence.
The history of human learning is almost as long as the history of life. It has experienced tens of millions of years of evolution from the monkey family to the Terran, and the organizational structure of the human brain has constantly adapted to human language ability. Human intelligence, knowledge, culture and civilization are acquired, supported by cerebral cortex, and the evolution of human brain organizational structure and acquired learning have made human intelligence, as shown in Figure 2. AI in the modern sense began with the attempt of classical philosophers to explain the human thinking process with the view of mechanical symbol processing. After the Dartmouth conference in 1956, AI was officially launched, and the research field of artificial intelligence was established at the conference [3]. In fact, the origin of artificial intelligence can be traced back to a long time ago. Before computers, there were abacus, slide rule, etc., which allowed thoughts, thinking and intelligence to exist independently from life. It began when humans invented languages and characters, which carried people’s thinking and intelligence. In turn, artificial intelligence promoted the evolution of human brain’s cognitive ability as a living thing, and machines could be used to simulate people’s intelligence.
Figure 2 The formation of human intelligence
Human intelligence begins with language, and language cannot be separated from context, pragmatics, semantics and grammar. The process of the invention of characters further gave birth to more human imagination, especially abstraction, association and interaction. Homo erectus, an animal hominid, created a stone culture 2 million years ago. After the long evolution of Homo sapiens 300,000 years ago and modern human characters 30,000 years ago, human communication changed from imitation, posture, gestures, spoken language, pictures to characters. The earliest cuneiform characters appeared in West Asia [4], and the earliest characters in ancient Egypt were hieroglyphics, which appeared about 6000 years ago. The hieroglyphics were ideographic and later evolved into pictographic hieroglyphics. Ancient Chinese originated 3,000 years ago, and Oracle Bone Inscriptions, which was found in the Yin Ruins of Shang Dynasty in China, has a rich pronunciation system, which distinguishes consonants from vowels.
The most essential difference between humans and animals is that humans invented writing.All species on the earth rely on the biological instinct of natural evolution, plus limited practical experience in their own life [5]. Only human beings are different in expanding intelligence. After a person has given birth, his or her biological contribution to the intelligence of human species is completed. However, in fact, if his or her intelligence is extended to form artificial intelligence in vitro, its contribution to the development of human intelligence still exists, and human beings pass on knowledge through language. Linguists estimate that there are more than 6,900 languages on the earth. The evolution of characters has a similar source, and later forms different branches. Pictures, cuneiform characters, hieroglyphs, pinyin characters, oracle-bone inscriptions, etc., are constantly evolving until the symbols of various disciplines (such as mathematics, physics, chemistry and music) and even the language symbols of computer programming are developed. Various abstract concepts are expressed in words, and human thoughts, thoughts, opinions, skills, decisions, problem solving, etc. are expressed in words, engraved on media and printed in books. Life has stopped, words still exist, the intelligence of a specific person still exists, and the intelligence of a group still exists, becoming artificial intelligence and human civilization. Artificial intelligence is an extension of human intelligence in vitro, starting with words. Characters are the discrete carriers of continuous language, and words are wordless, but they are not far away, and they are not long. The most basic feature that distinguishes human beings from other creatures is to express people’s thoughts, thoughts, emotions and intelligence in words, and to become the interpreter of our souls. Words can exist for a long time without life and become a part of the environment.It has become the ecology of human cultural civilization and the basis of digitalization of cognitive space.
Man is the most learning species among thousands of species on the earth.
Education began in prehistoric times, and the earliest schools in the world appeared in the ancient Babylonian civilization in the two river basins. In 3500 BC, there were a large number of textbooks and homework for clay tablet students at the ancient city site of Sulupo in Babylon Sumer, Cuba, which proved that there was a "clay tablet bookstore" for basic training such as reading, writing and arithmetic in the two river basins. In 2100 BC, there was a corridor and two rooms in the ruins of Mali City in the two river basins (20 people and 40 rooms respectively) The earliest schools appeared in four ancient civilizations (ancient Egypt, ancient Babylon, ancient India and China). There were court schools in ancient Egypt in 2500 BC. In China, there were special public schools such as preface, school and school in Xia Dynasty more than 2000 BC, as well as private schools of Confucius in the Spring and Autumn Period. The development of a person’s cognitive ability, especially his or her learning ability, can’t be separated from his or her educational environment. The communication and inheritance of education can spread human intelligence rapidly in time and space, which makes people’s cognition and intelligence leap into the fast lane. For the first time in the history of life on earth, the only species that can use swarm intelligence and social civilization to spread and inherit the existing artificial intelligence to future generations through language, writing and education has emerged.
Humans can not only talk about concrete and real things in words and characters, but also create abstract concepts in cognitive space that physical space does not really exist. The remodeling ability of the complex nerve tissue in the outer cortex of the human brain forms memory, which lays the foundation for the second cognitive expansion on the basis of instinct. It is full of imagination and creativity, and has the instinct of learning, and knowledge is acquired by the day after tomorrow. Therefore, human beings are the most learning species among thousands of species on earth.
4. Education makes people’s intelligence develop from "present continuous tense" to "present perfect tense"
Science and technology formed by human intelligence has become the main content of school inheritance learning, not only supervised learning, but also guided learning and collective learning of students, as well as intensive learning. Knowledge is the food of cognition, and learning cultivates human inheritance, cognition and creativity. No species can spend a quarter of its life in classroom education like human beings. The advantage of education is that any new knowledge and intelligence acquired by any place, any nation or any country can quickly become the common cognition of all mankind, and the dissemination, exchange and instillation of knowledge are efficient, without personal practice, and they can be used and shared quickly. This knowledge is a social civilization formed by more than 100 billion people who have lived on the earth in tens of thousands of years. Through education, the accumulated knowledge and spiritual wealth created by human beings are passed down from generation to generation, getting rid of the single channel that intelligence evolves from generation to generation simply through genes. The "present continuous tense" that originally relied on biological evolution intelligence has been added with a new and dominant cognitive channel, that is, the "present perfect tense" that relies on education to develop intelligence.
Reading can change a person, while education can change all mankind, and intelligence is rooted in education. The starting point of human cognitive revolution is the invention of language, characters and symbols, which creates culture and civilization. These cognitions are "imaginary realities", which enable intelligence to exist independently from life, thus inventing education. The second cognitive revolution of mankind is to explore the objective world, explore matter and energy, and invent various power tools, sensing tools and intellectual tools. At present, human beings are entering the era of artificial intelligence, that is, the third cognitive revolution. By the middle of the 21st century, we have developed unconscious brain-like intelligence by using the research results of brain science, and formed a new generation of artificial intelligence that can interact, learn and evolve. According to the intention given by human beings, we have consistently served human beings, and human beings have invented thinking machines, which can be educated and expanded intelligence. In the future, the iterative development of intelligent human beings and intelligent machines will change the environment and transform themselves. There may be a fourth cognitive revolution in the future, which will be cognitive life, involving bioethics, reacting artificial intelligence to all kinds of living things in nature, and then reshaping life, including human beings themselves.
1. Education reform that keeps pace with the times: training and nurturing the endogenous motivation of students’ innovation.
Why is human being human? It should be said that the biggest difference from other species is that human beings conform to the evolution of natural human brain, form the greatest invention-education, and reform education with the times [6]. Words are the carrier of thinking activities, knowledge is the crystallization of group intelligence, and education is the means of inheritance and learning. Individual intelligence obtains group intelligence through education, and it is accumulated through repeated iterations of individual and group intelligence through inheritance and autonomous learning, which makes human beings enter the era of rapid development of intelligence. Education includes inheritance learning and autonomous learning, and cultivates the ability to think in natural language and various professional languages. Inheritance learning is to cultivate the ability to accept and use knowledge, to use explicit knowledge, to adapt to ecological civilization, and to apply internal effects from the outside to the inside, which is mandatory and guiding; Autonomous learning is the ability to generate experience, skills and knowledge through one’s own practice, to use tacit knowledge and practice repeatedly, to become instinct, to be born from the inside out, to form memories, and to have strong subjectivity [6]. In education, inheritance learning plus autonomous learning, supervised learning plus unsupervised learning, and individual learning plus collective learning can cultivate individual general intelligence, with the methods and abilities to think, analyze, explain and solve general problems, and cultivate human inheritance, imagination and creativity. Teaching is to make students have knowledge, teaching is to use knowledge, and education is to create knowledge.
Human intelligence is constantly improved through education, learning new knowledge and forming new cognition. Schools and teachers should focus on inheriting learning and imparting knowledge, and expand to cultivate the cognitive ability of human brain. It is better to teach people to fish than to teach people to fish. Education in the intelligent age is to cultivate students’ learning ability in school and even lifelong learning, improve human cognitive level and control the robot "new human". In this process, teachers are also practicing lifelong learning. From teaching "books" to teaching "learning" and then to teaching "education", it is actually a process from possessing knowledge to using knowledge and then creating knowledge, which is the reform requirement of the times for education. In addition, in the intelligent age, lifelong learning will also be given as a feature to machines made by human beings, which will continue to learn and serve human beings like human beings, which is the core of the new generation of artificial intelligence. The form of learning is interaction; The core of learning is understanding, which can be explained and proved; The result of learning is memory, consolidating or micro-reconstructing the existing memory network; Learning has become the basis for a new generation of artificial intelligence to explain and solve practical problems. When virtual teacher robots and coach robots participate in educational activities, the coordinated development of human and machines will effectively promote the progress of social civilization.
2. The core of thinking is abstraction, association and interaction.
Education has cultivated our thinking, the core of which is abstraction, association and interaction. In people’s cognitive space, cultivating cognitive thinking ability through computational intelligence and memory intelligence is also what we often call "spirit"; In the physical space, through perceptual intelligence and behavioral intelligence, the ability of body interaction is realized. There is a continuous cycle between physical space and cognitive space, as shown in Figure 3. There are two important perceptions in physical space, namely, spatio-temporal recognition and target (pattern) recognition, and spatio-temporal recognition represents position, navigation and time synchronization; Target (pattern) recognition includes target recognition, face recognition and so on, which is direct perception. Learning is the ability to explain and solve preset problems. The presupposition problem is a subset of the real problem, which is recognized. When the problem is solved, knowledge is formed and passed on to the next generation in school. Machines can accept guided learning and learn independently at the same time, which is the basis of explaining and solving new problems, while explaining and solving real problems is the purpose of learning, and the two promote each other. Only after explaining and solving the preset problems will the ability to solve and explain the real problems be enhanced. Therefore, to solve the four problems of where, how, why and what, cognitive space is not only a warehouse for memorizing knowledge, but also a sky for flying imagination.
Fig. 3 Relationship diagram between cognitive space and physical space
3. Machines can be used as the carrier of thinking, which can enhance the imagination of human thinking and cognition.
Schrodinger put forward the physical view of living cells [7], so if the machine is life, there is the life view of the machine, which we call cognitive physics. Correspondingly, the physical layer of life corresponds to the material of the machine; The biochemical layer of life corresponds to the energy and clock of the machine; The physiological layer of life corresponds to the electronic circuit and machine instructions of the machine; The psychological layer of life corresponds to the operating system and middleware of the machine; The cognitive layer of life corresponds to the high-level software and data of the machine. Life depends on negative entropy. There are matter, energy, structure and time in the machine. Clock depends on energy, time depends on clock, and order depends on time. Time is the cornerstone of machine cognition. Structure and time are parasitic on matter and energy, forming a hard structure, filling the gap between matter, energy and information (structure and time), making information and matter inseparable; Structure and time are virtual beings in cognitive space, which we call soft structures. Soft structures are the elements of thinking, supporting image thinking, logical (linguistic) thinking and intuitive thinking, and reflecting people’s imagination and creativity. Machine bootstrap realizes thinking automation, self-reuse realizes cognitive self-growth, machine operation depends on program, program depends on time sequence, software depends on interaction, and time sequence and interaction produce negative entropy. The clock keeps on, interacting with the outside world, thinking and cognition. Human thinking and machine thinking are isomorphic in mathematics and homologous in physics, supported by energy and dependent on negative entropy for a living. Therefore, the machine can be used as the carrier of thinking.
One of the most important strengths of intelligent machines is violent thinking. To give a simple example, in 200 BC, Archimedes raised the precision of pi 1,700 years ago from 3.1 to 3.14, and in 500 AD, Zu Chongzhi got the pi value of 3.141,592, which took a total of 2,400 years. It took only 70 years to calculate it with a computer designed by Turing computable model, and raised pi to 1012 decimal places, as shown in Figure 4. Machine violence replaces infinity with large enough, and infinitesimal with small enough. Picosecond (10-12 seconds) can be used as time precision to control the time sequence period and execute recursively. As a biological human brain, its physiological response precision is only milliseconds (10-3 seconds), and it is beyond its power to solve the complex problem of exponential explosion. If a piece of paper can write 60 lines, and each line can write 17 digits, it will take 1 billion pieces of paper to finish. When the papers are stacked together, the stacking height will be 100,000 meters! Therefore, it is normal for machines to have more computing power than human beings. There is no need to make a fuss, whether it is protein’s folding prediction, AlphaGo’s program competition, or ChatGPT’s superior language understanding ability. From this point of view, machine violent thinking can complement human beings and greatly help human beings to improve their thinking and cognitive imagination.
Figure 4 Machine violent thinking helps human beings to improve their thinking and cognitive imagination.
The impact of artificial intelligence on society is all-round, but the impact on the industry should be educated first [8]. Artificial intelligence impacts prenatal education and preschool education, primary and secondary education and vocational education, general education of all kinds of majors [9], re-education after work, and all-round education, which is everywhere and ever-present.
Artificial intelligence also impacts all elements of education, including teachers, teaching environment and means, and teaching objects. In the era of intelligence, great changes have taken place in education. For teachers, we can replace teachers with virtual famous robots, and teachers no longer need to go back and forth for classes. For the teaching environment and means, textbooks and classrooms can be turned into virtual classrooms and personalized teaching platforms, where everyone can do different things; As for the object of teaching, it has also changed. Students can be robots, adding robot students-virtual digital people and physical robots. How to train robots to keep pace with the times? Should we train a machine teller in a bank or a person in a certain position in the customs in our education work? If 50 years later, 50% of the courses are taught by virtual masters, 50% of the students and 50% of the robots are listening, and the remaining 50% of the students are listening online, what is the scene? Therefore, the impact of artificial intelligence on education is all-factor.
The history of human cognition does not develop in a straight line, but is an evolutionary process of spiral cycle. Human cognition and artificial intelligence advance iteratively, develop together, learn how to learn and learn how to think [10], and human society has been cast into what it is today. Education is changing the fate of all mankind, and science and technology are the first driving force of human activities. With the iterative development of human intelligence and artificial intelligence, education has a new connotation.
Chinese literacy is thinking literacy, which is beyond discipline.Human beings bear the brunt of language intelligence. Humans use soft structures such as language, characters and symbols as carriers of thinking, so that thinking can be separated from living things and implanted into machines, simulating simple but cumbersome recursive calculation of living things, forming history, spirit, science and technology, culture and civilization; Under the hammer of words, philosophy, religion, law and human rights, state and politics have also been forged. Science and technology and humanities are of the same origin, so it is a misunderstanding to put Chinese teaching in liberal arts. Chinese carries thinking, and Chinese progressive thinking can be promoted. Everyone, especially intellectuals, will study for life, learn Chinese for life, expand their thinking and let their imagination fly.
Digital teachers teach by robots, and teachers become coaches and counselors.Some disciplines have made little progress in cognition for decades and tend to be mature and stable; In some disciplines, the cognition of several outstanding figures has greatly activated the frontier and development of the discipline. Therefore, the form of school classroom education with fixed time, place and personnel has been impacted for hundreds of years. The knowledge points of teaching materials of various disciplines can be flexibly loaded into machines, and classroom lectures are standardized and modularized. Virtual robot teachers are divided into famous teachers, which weakens the time and space walls of schools and disciplines, emerges "golden lessons", popularizes "micro lessons" and eliminates "water lessons". The scale of virtual classrooms and virtual simulation experiments can be too large or too small, and the lectures of virtual famous teachers will be rapidly popularized.
Teach machine learning and train machine successors to work.Take our research on unmanned driving as an example [11,12], there are three steps as follows, as shown in Figure 5. The first is driver operation and robot learning, which is guided learning; Then robot operation and driver intervention, which is semi/weak guided learning; Then there is robot operation and robot self-learning, which is autonomous learning, and the feedback from back to front is repeated many times, and the conversion is uncertain, sometimes it returns to supervised learning, and sometimes it returns to semi-/weakly supervised learning. Guided learning includes preconceptions, tasks, guidance, doubts, doubts, mutual cognition, supervision, etc. Autonomous learning is an important link to turn the results of guided learning into long-term memory. It can be seen that it is not an easy task to train machine successors. A few years ago, unmanned driving was paid too much attention to the automation level from L0 to L5, and automatic driving was regarded as an automation project, but the self-learning and self-growth of the robot driving brain were ignored. Only by continuous learning and iteration can it become a good machine driver.
Fig. 5 The learning process of training machine to replace people’s jobs-taking unmanned driving as an example.
Turing test of examination, assessment and evaluation [13] is normalized and personalized.Artificial intelligence has promoted the transformation of the traditional examination, assessment and evaluation mode. Taking Shang Tang "Yuanluobo" robot as an example, Turing test has built-in 26-level difficulty chess game, more than 100 pieces to deal with, independent observation of chess game changes, calculation of chess moves, taking chess moves, millimeter-level operation accuracy, second-level time response, "hand-eye" coordination, clean movement and compact rhythm. It has the authority certification of chinese xiangqi association of the State Sports General Administration, and supports the evaluation of chess grades of 16-13. In the future, all kinds of professional qualification examinations in the society will be changed, including the national college entrance examination.
Man and machine learn from each other and innovate together.The core of thinking is abstraction, association and interaction, and more is the creation and connection of soft structures. Machines are increasingly replacing many intellectual and technical jobs that human beings used to do. Teaching machine learning and homework, and studying and homework with machines will become the normal state of people’s life and work. The result of learning is to fine-tune the long-term memory in the machine, that is, to fine-tune the network topology of artificial intelligence trace cells. Autonomous learning is an important link to transform working memory into long-term memory. Fortunately, the machine can be copied in large quantities, and the machine itself can continue to learn. Interact with machines, people teach machines, machines teach people, and cooperate with innovation. One day, there will be a large number of famous machine teachers, digital people and human teachers, machine engineers create new material formulas, and machine scientists put forward new assumptions, which will drive new scientific discoveries.
Reading changes one person and education changes all mankind. We have developed "abstraction" from the symbolism school of artificial intelligence [14], "association" from the connectionism school, and "interaction" from the behaviorism school to create thinking machines. Therefore, intelligent machines are to human intelligence, just as books were to thinkers, telescopes to astronomers and microscopes to biologists. Machines use soft structures to extend and expand people’s thinking (memory intelligence and computational intelligence), which not only frees people from heavy repetitive work, but also better meets the standardization requirements of corresponding jobs (embodied intelligence). More importantly, they can think violently, teach and learn from each other between people and machines, and interact with each other to innovate. The problem of educational reform in the intelligent age has been urgently placed in front of all mankind. Let’s meet this learning revolution!

A few days ago, in the third "Love and Profession" activity in the first season of "Teacher Talk" in Guangzhou in the new era, held by the Bay Area Experimental School in Nansha District, Guangzhou, the digital twin wisdom teacher training meta-universe platform developed by Guangzhou Open University was officially released. This is one of the first practical projects of educational metauniverse in national colleges and universities, and it also marks an important step for Guangzhou Open University to comprehensively promote educational intelligence, explore the educational model of metauniverse, and promote the professional development of teachers in Guangzhou.
As the main implementation unit of Guangzhou’s "Pilot Area of Artificial Intelligence Boosting Teacher Team Construction of the Ministry of Education", Guangzhou Open University actively builds a regional teacher development big data center and artificial intelligence engine, expands the platform and resources of teacher education through multiple channels, builds a "smart teacher training" system for primary and secondary school teachers, and promotes the in-depth integration of new technologies and education and teaching. And through the collaborative innovation of enterprise alliance, we cooperated with China Telecom to research and develop the "Wisdom Teacher Training Metauniverse", which achieved remarkable results in the construction and application of Metauniverse. In 2022, the "5G+ Metauniverse Wisdom Teacher Training Construction" project won the third prize of the fifth "Blooming Cup" 5G Application Collection Competition of the Ministry of Industry and Information Technology. In 2023, the project "5G+ Wisdom Teacher Training Meta-Universe Platform Helps the Construction of Primary and Secondary School Teachers" won the third prize of the first "Xingzhi Cup" National Artificial Intelligence Innovation and Application Competition on Ecological Construction sponsored by the Ministry of Industry and Information Technology and the Ministry of Science and Technology.
Guangzhou Open University and China Telecom’s technical team set up a digital twin metacosmic scene platform for this activity for the first time. From the aspects of technology, adaptation, scene, function and other applications, the functional applications of learning, socializing, meeting, activities and other scenes in the metacosmic space were fully demonstrated, providing more than 40 online teachers and offline participants with an immersive experience of three-dimensional, virtual and real integration and multi-sensory interaction. On-site participants can not only roam the virtual venue through the big screens on both sides of the venue, but also wear VR equipment in the meta-universe experience activity area to experience the virtual venue space; At the same time, online participants who enter the teacher’s meta-universe space can choose digital virtual characters to sit down and listen to lectures, realistically reproduce the real scene of the venue, build a three-dimensional integrated space scene, and immerse the meta-universe venue with real-time online interaction.
In this activity, Guangzhou Open University showed the participants the application functions of the "Wisdom Teacher Training Metauniverse" platform, mainly in the following aspects:
In the technical application, through the wisdom teacher training the scene construction ability of the cloud platform in the meta-universe, the layout of virtual space scenes, characters and content elements is built; Engineering development of 3D content and business logic through the key technology and capability base of cloud platform in the meta-universe; Support flexible deployment methods such as public cloud, private cloud and hybrid cloud through the convergence ability of platform and cloud network in the meta-universe cloud; Through digital multimedia technologies such as VR and digital twinning, 3D modeling is carried out for teaching and training elements such as characters, environment and props to create a multi-dimensional immersive classroom; Using artificial intelligence, speech recognition and other technologies to enhance the interactive effect.
In the adaptation application, the digital twin wisdom teacher training meta-universe adopts communication technologies such as 5G communication and cloud network convergence to broaden the application dimension, and supports multi-terminal access experiences such as mobile phone, VR, PC and cloud rendering.
In the scene application, according to the original teaching and training scenes, the design innovation was carried out, and technologies such as 5G, VR, digital reconstruction, live broadcast and virtual digital were used to create a number of immersive online education and training scenes for the first time, namely: public service hall (customized classroom of Education Bureau), ladder classroom (meta-universe classroom) (classroom teaching theme), conference discussion room (meta-universe interactive room) (interactive discussion and training) and school auditorium (meta-universe).
In terms of functional application, the built scenes all support multi-person online collaboration in different places, and realize multi-person communication, discussion, interaction and other activities.
The event was broadcast live online to teachers in the city, and more than 400,000 viewers attended the event online, witnessing the application of the digital twin wisdom teacher training meta-cosmic technology, which was a complete success. In order to break the limitation of geography and time and space, realize the new format of online and offline integrated teaching and research in different places, and solve the problem of unbalanced educational development between regions, schools and urban and rural areas, a successful social experiment was carried out, which was an important practice for further promoting the construction of teachers’ team with new technologies such as artificial intelligence, empowering educational innovation, and promoting the modernization of education in Guangzhou with the high-quality development of "smart teacher training".
The remaining temperature of the 2022 Super League still exists, and the hot-blooded football season of Rizhao International Football Center reignited in 2023. The reporter learned from Rizhao Sports Bureau that the women’s Super League of China Football Association in 2023, the women’s U16 of the second China Youth Football League in 2023 and the men’s U19 of the second China Youth Football League in 2023 were settled in Rizhao.
It is reported that at 15: 00 on March 12th, in the third round of the Women’s Super League of China Football Association in 2023, Shandong Sports Lottery Women’s Football Team will play against Beijing Women’s Football Team at Rizhao International Football Center. Shandong Sports Lottery Women’s Football Team was established in November, 1983. It is one of the provinces that launched women’s football and established women’s football teams earlier in China, and it is also a key area for the development of women’s football in China. The level of women’s football in Shandong Province was in the leading position in the whole country, and it achieved excellent results in the national women’s football competitions for many times. The match between Shandong Sports Lottery Women’s Football Team and Beijing Women’s Football Team is the first home game of Shandong Team in the Women’s Super League this season (the other home games are held in Shandong Sports Center Stadium in Jinan).
The first stage of the women’s U16 Group of the 2nd China Youth Football League in 2023 will start on March 13th at the training base of Rizhao International Football Center and the football training base of Rizhao National Seaside Forest Park. Eleven teams from different cities in the country gathered in Rizhao to launch a wonderful confrontation in a ten-day competition.
The first stage of the men’s U19 group competition of the 2nd China Youth Football League in 2023 will start on March 26th, and the competition will last for 10 days. Eight 19-year-old men’s teams from different cities in China will participate in this competition. (Reporting by Ding Zhaoxia, a client reporter of Volkswagen Daily)

The key bottleneck restricting the development of advanced equipment is to meet the requirements of advanced resin composite materials with high strength, high temperature resistance and light weight. At present, such a difficult problem is expected to be solved. The reporter learned from East China University of Science and Technology that the first domestic polymer material genome research and development platform (AI plus polymer software platform) developed by Professor Lin Jiaping’s team was recently released in Shanghai.
The software is called "polymer version of ChatGPT", which contains the first database of resin structure and properties and chemical reaction between groups in China. Users only need to input the resin structure, they can quickly obtain its mechanical, thermal and dielectric properties, and can also make performance prediction and high-throughput screening through this software, so as to develop high-performance polymers and their composites with faster efficiency and lower cost.
"The research and development of new materials has entered the era of intelligent manufacturing from the era of trial and error of scientists." Lin Jiaping introduced that in the past, it often took 2-3 years or even longer for a new material to go from design, experiment to productization. Now, relying on this "polymer virtual laboratory", R&D personnel can find the optimal solution of structural design and formula optimization only through 2-3 iterations, and the experimental time is greatly reduced. The team will join hands with the industry to promote the development of AI plus polymer research paradigm to the whole industry chain.
Powerful database and forecasting system lead the industry.
What are the highlights of the AI plus polymer software platform? Lin Jiaping introduced that as an important achievement in the cross field of AI and digital technology and polymer materials, a powerful database is an important support of the platform and can be described as the cornerstone of material genetic engineering. The first database of resin structure and properties and chemical reaction between groups established by the team in China contains nearly 150,000 performance data of more than 34,000 polymers and nearly 1.4 million chemical reaction data of 58,516 basic reaction templates.
It is worth mentioning that these data mainly rely on dozens of graduate students and undergraduates in the past three years, especially during the epidemic, to standardize, enter and store them one by one. Based on the database, the team created a machine learning prediction model for more than ten properties of polymers, and built a research and development platform for polymer materials genome, which has multiple functions such as data retrieval, performance prediction and formula optimization.
The reporter saw in the team’s live demonstration that when users use the AI plus polymer software platform to predict the performance of polymer materials, they only need to click "Draw Structure" first, input the drawn strings of epoxy resin and curing agent into the corresponding input boxes, and then click "Start Prediction". After a few seconds, the page will return to the performance prediction data of epoxy resin calculated in the background.
So, how does this software compare with foreign counterparts? For example, Gao Liang, one of the team members and a special researcher at East China University of Science and Technology, has similar software in the United States and Japan. However, in terms of database richness, prediction accuracy and functional diversity, AI plus polymer software platform is superior. "Our goal is to seize the opportunity of digital and artificial intelligence to change the new material industry, develop high-performance polymers and their composites with faster efficiency and lower cost, and realize the original innovation and intelligent manufacturing of polymer materials." Gao Liang said.
The research and development of new materials has entered the era of "intelligent manufacturing" from the era of experience "trial and error"
The development of AI plus polymer software platform can be described as a sword after ten years. It is reported that since 2011, Lin Jiaping’s team has seized the frontier field of material research-material genetic engineering to start related work.
With the cooperation of gene combination screening and AI tools, the team developed a series of advanced composite matrix resins. For example, the curing temperature is less than 300℃, the 5% thermal decomposition temperature is more than 650℃, and the glass transition temperature is more than 600℃. For another example, a new type of high-temperature resistant and high-toughness poly (alkynyl imide) resin is superior to polyimide in processability, heat resistance and interface properties, and its mechanical properties are equivalent to polyimide. Related new resins have been evaluated by many aerospace institutes for the performance of composite materials and components.
"The AI plus polymer software platform is like a polymer virtual laboratory. The virtual design of the platform and the method of high-throughput prediction will greatly improve the research and development efficiency." Lin Jiaping introduced that at present, the platform has been tried in more than ten enterprises such as Shanghai Huayi Group Resin Factory, Shanghai Aerospace Eighth Institute, Jinfei Carbon Fiber Technology and Jinshan Petrochemical Institute, and will be used to the public.

Shen Zijie, 71.4%, with 10.5 points.
I believe that the low hit rate is only temporary, and hard-working fans can see it. Come on, everyone!
Netizen: National team players should be given more support and encouragement. They play for their country during the off-season. No matter what the result is, they have to face the influence of fatigue, injury and epidemic infection, and they have not systematically prepared for war with their respective teams. However, they are all the best players in China, and they will recover to their best level after several matches. Come on!
Netizen: Just looking at each person’s score when playing ball can’t explain his ability. Some of them rarely throw LAN but specialize in assists. Because he is too defensive to throw, he scores less. Just as a volleyball free man specializes in receiving and making fewer mistakes, can he say that he doesn’t score?
Netizen: After watching these national players, we understand a truth. The men’s basketball players in China have inherited the mantle of men’s football, and step by step they have slipped into the abyss of being spurned by Chinese people. Look at the women’s basketball team. Have a good reflection.
Men dressed into the sea, unexpectedly the sea of ??tide! He could not move directly on the stone! What is even more dangerous is the fluent water of men! Fortunately, the rescue team arrived.
At about 13:00 on August 29, the Fire Rescue Brigade of the Pudong New Area Diaoshuihu Fire Rescue Station received an alarm and said,In the waters near Nanhuizui Park, a person crosses the sea to prevent the flood dam, and the ocean will rise rapidly because the stones trapped in the flood.After receiving the report, the fire rescue staff rushed to the scene to carry out rescue.
After arriving at the scene, I found fire rescue workersAt this time, the tide of tide is extremely rapid. Who does not understand the water because of the trapped man, in order to prevent being involved in the wavy in the sea,On -site commanders immediately assigned a group of experienced underwater rescue teams to allow personal protection measures, paddle methods, planned to be trapped in advance, soothe their emotions, and see its state.After wearing a life jacket, the two players guided the trapped men to stun the paddle board, and the left and right sides of the slurry.Essence However, since the storm, in order to ensure absolute safety, the two team members have to slow down the beach.
(It has nothing to do with the figure)
Soon, the assault ship had been transported to the beach. Immediately, another group of fire rescue workers drove the fence and quickly drove to the difficult people. After two groups of consecutive words, the fire rescue personnel transferred the trapped personnel to the impression, and it quickly transported it to the shore.
Finally, it does not need 10 minutes. The trapped person successfully rescued. It is reported that the trapped person was not injured due to timely rescue. Return to sohu, see more

The latest news from Europe 5G communications is: 11 company CEOs, including German telecommunications, Vodafone and other European telecommunications companies, jointly vocal, they said: 5G construction cost is too expensive. They said: Large-scale technology companies have used a lot of traffic, which has been gains, but now the network cost is too expensive, so these scientific giant industries must pay some profit subsidies.
According to reports, after the United States, the US has begun to sell its own 5G network after the 5G technology of China Huawei. At the same time, "spectrum auction" as a shake money tree, and for this "use rights", each telecom company needs to pay 5-20 each year Billion dollar costs. However, now these telecommunications companies have begun "rebellion", requiring the US Science and Technology Giants to take part of the cost of European telecommunications networks.
Record 2018, the British Maogan announced the ban on Huawei, then Australia, Canada, New Zealand, Germany, France, Japan, South Korea, India, etc. Before Trump drove, Huawei’s family is not a bamboo to his 5G technology chest, thinking that Europe will not follow the United States to ban Huawei 5G technology, why? Because the world can meet the cost requirements of 5G commercial use.
Here is a technical problem, these countries can refuse Huawei equipment, but they cannot refuse Huawei patents, and to listen to the United States, give up Huawei equipment, it is necessary to pay technical patents to Huawei. Moreover, Huawei’s 5G network standard patent is basically basic and Qualcomm flat. Therefore, Europe may be taken to the ditch by the United States. But two or three years, "Report" is coming. The European large communications companies can not support the cost of distortion.
Also in 2018 to 2021, many big cities in China, as long as you have 5G mobile phones in your hand, almost no obstacles have no burden use 5G signals. Moreover, after the introduction of the first 5G mobile phone in 2019, the major mobile phone manufacturers have no longer release 4G mobile phones, no matter which level of mobile phones, medium, low, is 5G mobile phones.
What exhages China’s 5G network construction has developed? According to the information released by the Ministry of Industry and Information Technology, China has built 5G base station, more than 1150,000; almost all prefecture-level urban areas, and more than 97% of county urban and 40% township areas have achieved 5G network coverage. The number of all end users is 450 million. Is this a concept? According to statistics from well-known research institutions, the current global 5G base station is only 1.65 million, which means that China’s 50% of the global 5G base station accounts for more than 80% of 5G end users.
According to the "14th Five-Year Plan" planning, by 2023, the number of 5G base stations built in China will reach more than 2.5 million, 3.6 million in 2025, and 5G user penetration rate will reach around 60%. It can be seen, a big step in two years. This is also the key to China’s intelligent terminals, smart cars, etc.
According to reports, the reception of China’s 5G network construction is the efforts of three operators and 5G suppliers, but the main hero behind is Huawei. Huawei not only masters a lot of 5G patents, but also the only supplier of "5G-to-end technology" solution. Why can Huawei provide "5G-to-end technology" solution? Because Huawei’s product line is very rich, from wireless to wired, from access, exchange, data, transfer to the server, from hardware to software, Huawei has its own product. It is unfortunate that Huawei has been blocked in the international market, and abandoned Huawei countries, and its 5G orders were divided by Ericsson and Nokina. However, now they have begun to taste expensive tastes.
