At the meeting that nature liked, musk was bombarded by “the father of brain computer interface”: I didn’t agree with a word he said

Miguel Nicolelis, a neuroscientist at Duke University School of medicine, is the father of BCI. In the middle of this year, Miguel explained the original intention of BCI and its development. In addition to the “father of brain computer interface”, this year’s we conference also invited the top scientists in the industry to share the most noteworthy scientific breakthroughs and cutting-edge ideas in this year. Due to the epidemic situation, Miguel did not come to the scene to explain. However, this did not affect the experience of science communication in we conference. < p > < p > in short, it is to collect the electrical signals from the brain when the subjects are ready to move their bodies in real time, and then convert them into digital instructions that can be sent to the artificial execution device in less than 1 / 3 second. < / P > < p > through continuous training, Miguel team successfully let this monkey sit in a chair naturally, and just through “thinking”, successfully let the robot control the cursor, complete the “rules of the game”, and drink his favorite orange juice. After making such a discovery, Miguel and others found that the significance of BCI is far beyond the new brain research method they have been looking for for for 38 years: < / P > < p > therefore, they have created a computer electronic bypass, which will collect the EEG signals around the injury site and transmit them in digital form to a new wearable mechanical body. < / P > < p > they use flat sensors just attached to the surface of the patient’s scalp to record computer signals, and then let patients watch and train in a virtual environment. < / P > < p > after the patients are proficient in the virtual environment, Miguel asks them to use mechanical walking aids, and finally installs them with designed exoskeletons. At the opening ceremony of Brazil World Cup in Sao Paulo at 3:30 p.m. on June 12, 2014, Miguel’s brain computer interface made billions of audiences around the world boil. < / P > < p > that is to say, during the time Miguel trained for him, he had 7 vertebrae, which restored the function of perception, movement and motion control! During the dialogue with miguels, the safety of implantable protocols such as musk neuralink craniotomy was discussed. He thinks: < / P > < p > and musk neuralink’s experiment is to plant more than 1000 electrical levels on live pigs, all of which are very thin metal needles. If a needle goes in, along with these movements, there must be damage to the brain. Therefore, the next generation of brain computer interface electrode research and development, need to use similar metal with conductivity, and to have the same flexibility as human brain. The person who said this is Professor Bao Zhennan. She is the first Asian woman to serve as the dean of Stanford University, and she is known as the “material master” in the field of artificial skin. < / P > < p > the functions of mobile phones will be integrated into the clothes we wear, the electronic devices we attach to our bodies and the electronic devices we plant in our bodies. < / P > < p > the first problem is that the electronic materials used can no longer be rigid and fragile. They need to be soft, stretchable, self repairing and even biodegradable like skin. < / P > < p > the third problem is that the signals received by the artificial skin need to be combined with the human body. In other words, the skin feels different senses, but if the brain can’t process these signals, it still doesn’t feel. < / P > < p > from the molecular point of view to design, and then use chemical reactions to produce, using different sequences of molecules to give different properties. Based on this principle, Bao’s team proposed to use self-healing chemical bonds to make electronic materials. < / P > < p > finally, these signals need to be transformed into signals that the brain can receive – electrical signals, which are directly connected to the nerves and transmitted to the brain through the nerves. As a result, although there are still many problems to be solved, the concept of “artificial skin” has been proved, and even brought a lot of inspiration. < / P > < p > for example, in the past, doctors gave up blood pressure tests because newborn babies’ arms were as thick as fingers and lacked important information. < p > < p > artificial skin will change our life in the future. It can make us communicate with each other more and understand each other more. < / P > < p > in the future world, when you can really use electronic skin to feel the surrounding situation, it is possible to measure the person’s mood and know whether she is happy or sad. < / P > < p > and when people touch fruits, in addition to tactile and olfactory perception, they can also detect the number of bacteria in fruits and whether they have been washed clean. From the ancient symbol and language of “Homo sapiens”, to the emergence of books and paper, the “contention of a hundred schools of thought” between China and the west, and the first / second industrial revolution, the efficiency of information exchange has been improving step by step. Pan Jianwei first introduced the basic concepts of “quantum”, “quantum superposition”, “quantum bit” and “quantum entanglement”. < p > < p > when people have the ability to adjust and control the qubits individually according to their needs, a new discipline called quantum information science has emerged. Pan Jianwei said that quantum communication can be an unconditionally secure communication mode in principle, and quantum computing can provide very powerful computing power for the research of various complex systems. This is due to the indivisibility and uncertainty of quantum, so once a “eavesdropper” wants to “plot against it”, it will be found. In addition, quantum entanglement can also be used to transfer the quantum information of a particle from one place to another without transmitting the object itself. < / P > < p > if there happens to be a mass of entangled matter in the laboratories of two places, then pan Jianwei in Hefei can operate with the entangled material to entangle him. Of course, the current technology can not do such operations on very complex things, it can only be a system composed of dozens, hundreds or even millions of particles. < / P > < p > it takes about 150000 years to decompose a 300 bit large number with a trillion times of classical computer, but when you use a trillion times quantum computer, it only takes one second. It is proved that two entangled particles have the function of “strange interaction between distant places” as Einstein said. < / P > < p > after 10-15 years, it can completely develop a wide area quantum communication network technology system with the integration of heaven and earth, laying the foundation for the formation of the next generation of national information security ecosystem. In the field of quantum computing, we hope that through the coherent manipulation of hundreds of qubits, we can solve some practical problems, surpass the current supercomputers, and solve some important scientific problems. < / P > < p > we can develop general quantum computing prototypes with basic functions to preliminarily explore the related applications of cryptanalysis and big data analysis. < p > < p > this time, without applause or cheers, Tencent’s chief exploration official website Dawei opened the “Tencent Science Week” in the empty venue of the North exhibition. < / P > < p > this is an iconic picture of the earth: the dim blue dot. It always reminds us to protect the only home. Scientists and astrologers have been searching for earth like planets and intelligent life, and constantly remind us how special the earth is. As like as two peas in the interview, Li Hang, vice chairman of the

Youth Development Committee, said in a interview with the qubits that the same stage was set up in the United States, Switzerland, the United Kingdom and Canada in the same period. < p > < p > Li Hang shared an experience. When he filmed Professor Victoria Kaspi, the catcher of rapid radio bursts in Canada, the Beijing team of Shenzhen team, the production team of New Zealand and the director team of the United States were all online across time difference and distance. < p > < p > for the first time, “offline film watching” was held in Lanzhou No.51 middle school, Hengshui middle school, Guizhou Normal University and other places, inviting students and teachers to discuss cutting-edge scientific topics. < p > < p > in the interview, one of the most popular words mentioned by Li Hang is “no return”. After doing so much and investing so much, it is simply for the purpose of better holding the science popularization conference and making the “science popularization” experience better. For example, Professor Nakai Nakai, who shared the project “xenogeneic cultivation of human organs”. He flew to the United States from Japan. After 14 days of isolation, he came to the studio to record his speech. For example, Stephen Weinberg, 87 year old Nobel Prize winner in physics, was the first scientist to accept the invitation. < / P > < p > and astronomer Jane Greaves, who discovered signs of life on Venus this time, agreed to attend the we conference shortly after the breakthrough. You know, it’s very difficult to hire that scientist when a general scientific breakthrough comes out. In the past eight years, Tencent has hired 82 scientists in total. When inviting guests at the beginning, Li Hang said frankly that it was still difficult. But now, with the recognition of scientists, it is much easier than ever to bring a “circle of friends” effect. However, there are still so many enterprises and so many scientists who invest “regardless of cost” and are willing to take practical actions to promote science and popular science, so that basic science can be radiated to every young person. Steven Weinberg, 87, is still invited to the we conference. At the end of the speech, I would like to encourage the younger generation of scientists: < / P > < p > is like handing the baton to us, hoping that the next Steven Weinberg, the next Hawking and the next Nobel Prize winner in physics can be produced among us. < / P > < p > this article is the original content of the signature account of Netease News · Netease account featured content incentive plan.
