Nobel prize in chemistry： researcher of lithium battery. Domestic experts： three professors deserve the prize.

John Goodenough (American, born in 1922)

Stanley Whittingham (American, born in 1941)

Akira Yoshino (Japan, born in 1948)

　　The 2019 Nobel Prize in Chemistry was awarded to American solid-state physicists John Goodenough, Stanley Whittingham and Japanese chemist Akira Yoshino in recognition of their contributions in the field of lithium batteries. The three scientists will share the prize of 9 million Swedish kronor (about 910 thousand US dollars) equally.

　　The reporter interviewed many professors from Nanjing University and Nanjing University of Technology. All the professors interviewed were unanimous: the three professors were well-deserved, especially the 97-year-old American solid-state physicist John Goodenough. "We all think that he should have won this award long ago."

　　He set a new record for the oldest person.

　　Haruki Murakami in the scientific community: 97 years old, working every day.

　　This year’s Nobel Prize in Chemistry, besides the winning project "People-friendly", another highlight is Goodenough, a 97-year-old award-winning scientist. Previously, this record was held by arthur ashe King, an American scientist who won the 2018 Nobel Prize in Physics at the age of 96. Because of Goodenough in the name (meaning "good enough"), Goodenough was also humorously called "good enough" by the outside world.

　　For many years in a row, the "good enough" old man has been nominated, but he has been in a state of running with him. "Everyone thinks that the old man should have won this award long ago." Zhu Jixin, a professor at the Institute of Advanced Materials of Nanjing University of Technology, said that Goodenough has been nominated for the Nobel Prize many times, which is almost the "Haruki Murakami" in the scientific circle.

　　Previously, Goodenough has made outstanding contributions in the field of magnetic materials. For him at that time, electrochemistry belonged to the nature of "playing with tickets". "Early batteries had low discharge capacity and energy storage density. Goodenough found lithium cobaltate with layered structure as the anode of the battery, and used metal materials other than lithium as the anode, which can realize high-density energy storage. " In this way, rechargeable lithium batteries can be commercialized.

　　Now, the "good enough" old man who is over 90 years old still goes to work in the small office of the University of Texas at Austin every day. To this, he explained, "My work is not finished yet."

　　"Good enough" in Professor Nanjing’s eyes: All-rounder in arts and sciences with high output, especially loving home.

　　Many professors interviewed by this reporter are no strangers to Goodenough. Professor Jin Zhong from the School of Chemistry and Chemical Engineering of Nanjing University told the reporter that Mr. Good enough is still studying new energy storage battery systems, especially high-safety solid-state lithium batteries, which maintain high-quality scientific research output every year. At some meetings, there is no lack of him. "He is very kind and approachable. He has many new ideas and has been breaking through himself. When he speaks the report, the organization is very clear. The articles he writes not only put forward new concepts, but also explain the principles very clearly. " Admiralty said that he has also taught a group of masters of making batteries, and his disciples are all in academia and industry.

　　In academic circles, Goodenough’s "all-rounder" is also famous. From philosophy and other liberal arts disciplines to lithium battery research and other fields of science and engineering, Goodenough’s learning and scientific research stories across the liberal arts and sciences have become the benchmark for future generations to marvel at. Professor Zhou Haoshen from the Department of Energy, School of Modern Engineering and Applied Science, Nanjing University, told the reporter that Goodenough was still a "special family lover" and his life was very warm.

　　prize motivation

　　They make the use of lithium batteries "good enough"

　　"The Nobel Prize in Chemistry was awarded to three scientists, which gave a shot in the arm to the new energy field that has not won awards for many years." Professor Jin Zhong of Nanda University said that the Nobel Prize in Chemistry has been awarded to research in biochemistry and other fields for two consecutive years. This time, Mr. "Good enough" won the prize at the age of 97, which can be said to be widely expected. The award-winning research on lithium-ion batteries is a systematic research with traditional electrochemistry as the core and involving physics, chemistry, energy and materials.

　　A Professor Hao Shen from Nanda Zhou introduced that the early nickel-cadmium batteries and lead-acid batteries had low energy density. In 1970s, Stanley Whittingham, one of the winners of the 2019 Nobel Prize, made the world’s first new lithium-ion battery with titanium sulfide as the cathode material and lithium metal as the cathode material.

　　B This is undoubtedly a great progress of mobile power supply, but it has a lot of hidden dangers, because lithium metal is active, so the battery will be in danger of explosion. In order to solve this problem, Goodenough predicted that if the positive electrode was made of a metal oxide containing lithium instead of a metal sulfide, the battery would have a greater potential. In 1980, Goodenough invented the most important component in lithium batteries, lithium cobaltate cathode material. Nowadays, most portable electronic devices all over the world use this cathode material.

　　C Since then, Japanese scientist Akira Yoshino has discovered that the negative electrode can be made of carbon material and does not contain any metal. Matching the positive electrode discovered by Goodenough, he invented the first commercially feasible lithium-ion battery in 1990. Instead of using metallic lithium as the cathode, he used graphite, a carbon material that can insert lithium ions like lithium cobaltate as the cathode.

　　In 1991, the lithium-ion battery jointly invented by Akira Yoshino and Goodenough was put on the market by Sony, which marked the large-scale use of lithium-ion batteries. The original brick-like "mobile phone" no longer exists, and it is replaced by a thin mobile phone that uses lithium batteries and "slim down" the parts together.

　　At present, both electric vehicle technology and mobile electronic technology are based on the vigorous development of lithium batteries, which makes our life "good enough".

　　How to solve the problem of battery spontaneous combustion and slow charging?

　　"Super Battery" is on its way.

　　The cooperation between Akira Yoshino and Goodenough has made the lithium battery with high explosion risk safe, but readers will surely ask, why do the news of spontaneous combustion or explosion of mobile phone batteries still occasionally appear in newspapers? Admiralty explained that the fire and burning accidents of mobile phones and electric vehicles will be reported every once in a while in the news, precisely because the safety of lithium batteries is still not satisfactory. It can be said that people are still not completely satisfied with the performance of lithium-ion batteries, and further technological innovation is needed to develop a battery with high energy density, good safety, long cycle life and no pollution to the environment, which is exactly what people are looking forward to.

　　In addition, our common "complaints" about the lack of fast charging and large capacity of lithium batteries are also the future development direction of lithium batteries. Zhou Haoshen said that the "technological revolution" of lithium batteries is still on the road, and there are three main innovations: the energy density, power density and safety factor of batteries should be made higher. But there is a problem that you can’t have your cake and eat it. Therefore, Goodenough, a 97-year-old "good enough" old man, still insists on the front line of scientific research, just to solve these problems. Perhaps in the future, "super battery" will be successfully born, and new electrons with high energy density, such as lithium air battery, metal battery and lithium sulfur battery, will better change our lives.

　　A doctor from NTU has just become a "good enough" postdoctoral fellow.

　　In Nanjing University Institute of Technology, Zhou Haoshen’s lithium battery research group specializes in the research of new electrochemical energy storage materials and technologies, including lithium-ion batteries, and keeps in communication with Goodenough’s research group.

　　The reporter learned that a doctor who graduated from Nantah Institute of Technology also successfully applied for a postdoctoral position in Goodenough’s research group, officially went to the United States in September this year and began to follow Professor Goodenough as a postdoctoral position. Professor Zhou Haoshen revealed, "Yesterday, the postdoctoral fellow was still with ‘ Good enough ’ The old man discussed the work of NTU solid lithium air battery and agreed to cooperate.

Is Tesla FSD ＂Catfish＂ about to enter China？ Set a high-level intelligence to drive PPA head-on

Tesla FSD will enter China, can domestic car companies still fight? According to media reports, "Chen Kele, deputy director of the Intelligent Manufacturing Promotion Department of Shanghai Economic and Information Committee, said that in the next stage, Shanghai will further deepen its cooperation with Tesla, promote the layout of functional sectors such as autonomous driving and robots in Shanghai, and jointly build a technology industry cluster with core technological advantages and facing the global market."

This news has also been interpreted by the outside world as a signal that Tesla FSD is about to enter the China market. If so, then an overseas "catfish" is finally coming.

Tesla has been deeply involved in the field of autonomous driving for a long time, but can the late FSD still penetrate the smart car market in China? After all, during the absence of Tesla FSD, intelligent driving, including Tucki NGP, Huawei NCA, and even Jidu PPA, a company known as "automobile robot", has been accelerated, and China’s wisdom has changed.

The competition is raging, and the domestic intellectual drive is "anti-"roll"Tesla

Tesla is not only the leader of new energy vehicles, but also the promoter of autonomous driving. Since the release of Autopilot in 2014, Tesla’s assisted driving system has become a pioneer in assisted driving worldwide with its leading landing, rich functions and continuous OTA upgrade. When it comes to smart driving, Tesla is second to none.

However, times have changed. Standing in the smart car market in 2023, in the face of the fully blossoming domestic intelligent driving system, Tesla not only no longer occupies an overwhelming advantage, but even has the impression of being overtaken.

At present, almost all domestic smart cars already have very mature intelligent driving functions in high-speed and parking scenes, and are making efforts to assist driving in urban scenes.

For example, when Tucki launched Xmart OS 4.2 in March, it simultaneously released the first-stage capabilities of XNGP, and many of its models can open point-to-point city NGP (Intelligent Navigation Assisted Driving) in Shanghai’s high-precision map coverage area. In April, Huawei released the HUAWEI ADS 2.0 system. In the third quarter of this year, the urban NCA will realize the landing of 15 cities without maps, and in the fourth quarter, 30 cities without maps will be added.

When the limited edition of ROBO-01 lunar exploration was released in October last year, Jidu released the point-to-point navigation assistance PPA simultaneously. According to the official introduction, Jidu PPA has the high-level intelligent driving ability of "multi-domain integration" in high-speed domain, urban domain and parking domain. When ROBO-01 is delivered, the available scene coverage of PPA will reach the leading position in China. The proportion of cities in the scene of users using cars is much higher than that of high-speed and parking, so the "multi-domain integration" of PPA is the only way for high-level intelligent driving.

In addition, car companies such as Ideality, Weilai and even the Great Wall (mainly relying on its subsidiary) have similar promotion plans for urban intelligent driving.

It can be seen that Tesla, which once dominated, is full of uncertainty in the face of the competition in China’s smart driving market in 2023.

The competitive advantage of domestic intelligent driving is not only reflected in the localization of better understanding of China road conditions, but also in the leading hardware configuration. Take Tucki Expressway NGP as an example. By the end of August 2022, its accumulated mileage has reached 36.9 million kilometers. The concentration is backed by the technical empowerment of Baidu Apollo, which is not only the L4-level automatic driving ability, but also accumulated more than 50 million kilometers of test mileage. Complex "China characteristics" such as ghost probe, jam, and take-away riders all form a strong data advantage, which makes domestic intelligent drivers better understand the driving habits of China car owners and better adapt to the complex road conditions in China.

The hardware foundation determines the function of the upper software, and the domestic intelligent driver has been "armed to the teeth", and there are many volumes to be rolled. Among the representative brands of domestic smart driving, 500+TOPS computing power, 30+ sensors and laser radar are all embarrassed to take out their hands without being paired. For example, Aouita 11 is equipped with three lidar, Weilai ET7 and four Orin to pull the computing power to 1016TOPS. In addition to dual Orin X+ dual lidar, Qualcomm 8295 chip is the first to be equipped with the image convergence.

In addition to the efforts in configuration and function, the domestic intelligent driver has made multiple redundancies in safety. For example, two sets of automatic driving system perception schemes of "vision+laser radar" are applied in Jiji, which can work independently and be a safe backup for each other. In addition, the convergence has also achieved "cabin-driving integration". When the intelligent cabin domain control is extremely ineffective, the intelligent cabin domain control can take over the driving task, realize safe parking, and fully ensure the safety of intelligent driving. In addition to technology, it is the efforts made by China’s high-priced smart driving products in the popularization of science and technology.

Domestic intellectual driving technology equality,It is by no means a toy for a few people.

It must be said that Tesla’s software payment model has not only changed the business model of the traditional automobile industry, but has also been imitated by major manufacturers. However, Tesla FSD’s subscription price of 64,000 yuan is really not cheap.

The high price has discouraged many users. According to previous data, the opening rate of Tesla FSD in China is 1%-2%, and the opening rate in the global market is only about 11%, and it continues to decline. Moreover, at present, the domestic FSD is not a "complete body", which can be said to be a "castrated version" function.

Musk is also aware of this problem. In May this year, he released the news on his Twitter. Tesla will plan to provide all car owners in North America with a free one-month FSD fully automatic driving experience package, provided that the FSD is highly smooth and safe.

In fact, smart cars in China have also formed a relatively mature software payment ecology, and various optional packages for cockpit, software services and smart driving are extremely rich. At the same time, local smart car companies are also exploring new ways of playing, bringing leading functions to more users with the concept of universal technology.

Just like the limited edition of Jidu ROBO-1 lunar exploration, the official gave away many user rights and interests including high-level intelligent driving, charging and recharging, vehicle warranty, three-electricity warranty and so on for the users of lunar exploration, and they enjoyed it for life. Among them, the value of high-level intelligent driving is not less than 60,000 yuan, and it has achieved the first "following people but not following cars" mode in the industry, and you can continue to enjoy this right even if you change cars.

Xia Yiping, CEO of Jidu, even publicly stated that intelligence is standard in all departments, from the entry version to the high version, including laser radar and 35.6-inch integrated bottle. This move is tantamount to directly opening a new stage of high-level intellectual driving for science and technology inclusiveness in the domestic market.

In April this year, Ideality quickly followed suit, announcing that NOA software and services in the ideal AD Max 3.0 city will be free for life, and every AD Max user will upgrade the NOA in the AD Max 3.0 city and NOA at high speed for free.

The technology popularization of domestic smart cars is not the "backstab" of Tesla model, because technology should be popularized on a large scale instead of being lofty. With the hardware configuration and intelligent scheme of the centralized ROBO-01, there is no complicated "high-low matching" distinction. This uncomplicated and unconventional mode is not only completely different from other new domestic forces, but also a localized continuation of Tesla’s minimalist technology temperament.

Leading intelligent driving technology brings excellent driving experience to more car owners, which is the greatest significance of scientific and technological progress. At the juncture when FSD is about to enter China, a competition between local high-level intelligent driving and "overseas catfish" is also brewing.

Lingao Volleyball Championship ｜ Ding ‘an Team beat Haikou 3-1 to win the first game.

Original title: Lingao Volleyball Championship | Ding ‘an Team won the first victory with 3: 1 lecturing Haikou.

New Hainan Client, Nanhai Net February 18 th News (Reporter Liang Zhenwen) On February 18 th, the "Chinese Dream and Working Beauty"-"Witt Cup" 2024 Hainan (Lingao) Trade Union Elite Volleyball Championship was launched in Binjiang Park, Lingao County.

At the beginning of the third game, Haikou team continued the state of the previous game and led by 5:0. Ding’ an team can only call a time-out to make adjustments. However, because the whole team is not in the state, it still lags behind by 3:9. The Haikou team continued to maintain its state and continued to lead at 12:6 through blocking. Ding’ an team had no choice but to call a time-out adjustment again. By slashing and serving, they scored one after another and clinched the score at 13:15. Depending on the fierce chasing momentum of Ding ‘an team, Haikou team can only call a time-out for adjustment. On the 13th, Ding ‘an scored three points in a row by serving, and Ding ‘an led by one point at 16:15. Haikou team quickly adjusted its state and scored a 20:20 draw through smash. Entering the key points, Haikou team once again suspended the tactics, but the momentum of Ding ‘an team has started, and finally Ding ‘an team won the third game with a reversal of 22:20. Take a temporary lead with a big score of 2:1.

At the beginning of the fourth game, Ding ‘an team broke Haikou’s pass by serving and took a 5-1 lead. Continue to lead by 7:1 through smash. Haikou team can only call a 30-second short pause and rearrange tactics. Haikou scored 4:7 by spiking. Seeing that the Haikou team is gaining momentum, the Ding ‘an team is also called to suspend adjustment. Through the smash, the situation was stabilized with a lead of 9:6. Haikou team was full of momentum, scored successively by blocking and smashing, and overtook Ding ‘an team by 10:9. The Ding ‘an team called for a pause for adjustment for the second time, and the two teams tied for the first time at 12:12. Subsequently, at 16:16, 17:17 and 18:18, the scores of the two teams alternately led and tied. In the end, Ding ‘an team won by 21:18, with a total score of 3:1, and got off to a good start.

Table tennis World Cup： No.2 seed lost again! Olympic runner-up scored 2 empty games, and South Korea bombarded 8.

On December 7th, Beijing time, the contest of Chengdu table tennis mixed team World Cup quarter-finals kicked off on the second day. The first two games were Germany VS France and South Korea VS Slovakia. As a result, the second seed Germany lost again and lost to France 4-8. As for South Korea, it was a total victory, sweeping its opponents 8-0 and winning heartily.

At present, it seems that the No.2 German team is the weakest among the top four seeds. After all, the six main players didn’t participate in the war, and the rest of the people really couldn’t hold up the scene. The day before, they lost 4-8 to Sweden, and now they lost 4-8 to France. Shan Xiaona, the Olympic runner-up, is helpless!

Please see below for the detailed situation.

The situation of this game is relatively simple. Although Slovakia advanced to the quarter-finals, it was mainly because Germany and Portugal, the two strong rivals in the group stage, were short of a large number of core players. Even so, they made a thrilling pass, and now it is natural to play against the powerful South Korean team everywhere.

In the first set of mixed doubles, Lin Zhongxun/Shen Yubin beat Apras/Raposo Wa 3-0; In the second set of women’s singles, Tian Zhixi won Kukulova 3-0; In the third set of men’s singles, Li Shangzhu beat Wang Yang 2-0, and the Korean team ended the battle with a total score of 8-0.

The battle between Germany and France was the focus on December 7th. If all the main players of the two teams participated in the war, the German team was relatively superior. However, the four main players of the German men’s team, Ochalov, Qiu Dang, Francesca and Bohr, were absent, while the two main players of the women’s team, Han Ying and Mittham, were absent. Shan Xiaona was the only core player, which was really unsustainable. They lost to Sweden 4-8 the day before.

Compared with Sweden, the strength of France is obviously stronger. lebrun brothers and Pavard Ran Ran have risen, Simon is not old, Yuan Jianan is in his prime, and his strength can reach the top four in this World Cup. It is really difficult for Germany to win the other side.

Sure enough, the first set of mixed doubles German team fell behind, and meissner/Wanyuan lost to Alex/Yuan Jianan 1-2; In the second set of women’s singles, Shan Xiaona, the 40-year-old Olympic runner-up, won the 19-year-old Pavard 2-1; In the third set of men’s singles, European Games champion Felix beat Walter 2-1. Although the total score of the French team was 5-4, it still did not open the gap.

In the fourth set of men’s doubles, Walter/Steph lost to Alex/Simon 0-3, and the French team ended the battle with a total score of 8-4. The second seed Germany collapsed again, but it was really impossible.

Manchester United’s 29-goal striker returned to the training ground in the season.

Premier League Manchester United striker marcus rashford has returned from injury. Although I returned to the Clintons training ground and completed my normal training, the battle has not yet been decided. Manchester United will play the away game against the AFC Bournemouth team in the 36th round of the 2022/23 season in the Vitali Stadium in Bournemouth, England at 11pm on the 20th (Korean time). At present, Manchester United has played one game less than Liverpool, which ranks fifth. At present, Manchester United, which ranks fourth with 66 points, must play in the remaining three games in order to participate in the Champions League next season. The battle of Bournemouth, the first game of the last three consecutive games, is crucial for stabilizing the end of the season. Before the game, head coach Eric Teng Hach talked about the current situation of Manchester United’s available lineup. He said: "This is positive. Of course Raphael Balaam can kick. Scott McTomini also took part in the training. After seeing the training, I can completely participate in the competition. " If Balaam, who thought he was out of the season, returns, the weight of defense will rise. However, the main gun Rachford is still a question mark. Head coach Tenghahe said: "Rachford trained well all week. But in a bad state. I will observe for another day to see how much he has recovered, and then make a decision tomorrow. Rachford missed the 35th round match against wolverhampton wanderers last weekend. Whether Rachford can play is very important for Manchester United. This season, he scored 29 goals in all competitions, which is the team with the most goals.He scored 16 goals in the Premier League alone and played a central role in Manchester United’s attack. With fast speed as a weapon, he showed his excellent goal-scoring determination this season and spent the high season of his career. In addition, if Manchester United beat Bournemouth in the away game, they will be able to score four points with Liverpool ranked fifth and share equally with Newcastle United ranked third. Manchester United must win in order to get the fourth place in the Champions League. In addition, whether Rachford will play and lead the team to attack is also highly anticipated.

Lost again! Tuchel took office for a month and the third line was defeated. Bayern Sao swallowed the bitter fruit and the season was completely ruined.

For Bayern fans, it was a nightmare in the past month. It was originally thought that tuchel would lead the team to attack the Champions League as he did in Chelsea before, but unexpectedly, tuchel coached Bayern for seven games and lost three games and drew two games. As a result, the German Cup was out and the Champions League was out. After the 1-3 reversal of Mainz in this round, Dortmund defeated Frankfurt 4-0 in the later game, which meant that Bayern lost the top position in the Bundesliga again.

Although tuchel led Bayern to beat his arch-rival Dortmund 4-2 in the first game, tuchel’s team was not competitive in the next German Cup and Champions League because he took over the team for too short a time. We should know that Bayern, headed by nagel Mann, had maintained a total victory in the Champions League before, including the double win over Paris Saint-Germain, the double win over Inter Milan and the double win over Barcelona, but tuchel’s team was completely defeated by Manchester City 3-0.

The impact of the Champions League exit on Bayern is huge, which means that they only have the Bundesliga title to compete for this season, but the players seem to have not yet got out of the shadow of the Champions League exit. In this round against Mainz, Manet scored a goal in the opening 29 minutes to help Bayern take the lead in the away game. Unexpectedly, Mainz even scored three goals at home to complete a big reversal. Bayern’s last four games were unbeaten, with a record of 2 draws and 2 losses, which was disappointing.

Looking back now, it may be a very bad decision for Bayern to fire nagel Mann in the sprint stage of the season. Tuchel is not a god either. Although he once created miracles at Chelsea, it doesn’t mean that he can replicate it when he goes to Bayern. The change of coaches at Bayern’s top level ruined this season.

After the 29th round of the Bundesliga, Dortmund accumulated 60 points and 59 points of Bayern, taking control of the championship. There are five rounds left in the Bundesliga. Bayern’s opponents are Hertha Berlin, Bremen, Schalke, Leipzig and Cologne, while Dortmund’s opponents are Bochum, Wolfsburg, M? ncheng, augsburg and Mainz. If Bayern wants to win the championship, it needs to win the remaining games and expect Dortmund to make mistakes and lose points. If Bumblebee wins five consecutive victories, it will definitely win the championship.

GPT-4 is coming! Microsoft executives revealed that a new generation of artificial intelligence artifacts will be released next week.

If you are a technology enthusiast, you must have heard of the name GPT-3. It is a super-large language model developed by OpenAI, with 175 billion parameters, which can generate all kinds of text content, from novels, poems, news, dialogues to codes, emails, advertisements and so on. It is known as a milestone and revolution in the field of artificial intelligence.

But what you may not know is that GPT-3 is out of date. Yes, you heard me right. Just yesterday (March 9th), Andreas Braun, chief technology officer of Microsoft Germany, revealed in an activity called "AI in Focus-Digital Kickoff", "We will launch GPT-4 next week, which will be a multimodal model and provide completely different possibilities, such as video."

What? GPT-4？ Multimodal? Video?

These words make me feel both excited and confused. I immediately searched the internet for relevant information and found some interesting and important details.

First of all, what is a multimodal model? Simply put, it is a model that can handle different types of data (such as text, images, audio and video) and transform and integrate them. For example, you can describe a scene or a story in words and let the multimodal model generate corresponding pictures or videos; Or you can give a picture or video and let the multimodal model generate corresponding text descriptions or comments.

Does that sound cool? But it’s not easy to do. Because different types of data have different structures and characteristics, it takes a lot of computing resources and algorithm skills to map and understand them effectively. At present, some research teams have been exploring the multimodal field and made some progress, but none of them has been as comprehensive and powerful as GPT-3.

The GPT-4 revealed by Microsoft executives is a multimodal model, and it also contains video, the most complex and expressive data type. What does this mean?

It means that we may see more amazing and interesting artificial intelligence applications. For example:

You can enter any imaginary scene or story in words, and let GPT-4 generate corresponding video clips.

You can give a video clip and let GPT-4 generate a corresponding text description or comment, or give a different video style or theme, and let GPT-4 transform the content and form of the video.

You can ask a question in words and let GPT-4 generate a video tutorial or demonstration to answer your question, or ask a question in video and let GPT-4 answer your question in words.

You can input a lyric in words and let GPT-4 generate corresponding music and video, or give a piece of music and video and let GPT-4 generate corresponding lyrics.

Of course, these are just some examples I imagined at random. In fact, there may be more interesting and useful applications. Imagine if we can interact with artificial intelligence with natural language and multimedia data, then what powerful and convenient creativity and communication skills we will have!

However, before we are ecstatic, we should also pay attention to some potential risks and challenges. For example:

GPT-4 may be abused to create false or misleading information, such as fake news, fake videos, fake comments, etc., thus affecting public opinion and social order.

GPT-4 may threaten human originality and copyright, such as plagiarism, piracy and infringement, thus harming the interests of creators and consumers.

GPT-4 may exceed human understanding and control, such as unexpected or unpredictable results, behaviors or influences, which may lead to moral, legal and security problems.

Therefore, while we look forward to and enjoy the convenience and fun brought by GPT-4, we should also be vigilant and responsible, and use and supervise this technology reasonably. At the same time, we should also pay attention to and support those scientists, engineers, legal experts and ethicists who are committed to studying and solving these problems.

GPT-4 is a shocking and exciting technological progress, which will open a brand-new and colorful artificial intelligence world for us. I am very much looking forward to its official release next week, and see that it shows its infinite potential in various fields.

The reason of C Ronaldo’s bleak evening scene： mistaking the platform for ability

C Ronaldo has gone far away to the desert, so that the hot sunshine in the desert can cure the injury and pain of the defeated plum ball king!

At the age of c, he has gone to the desert, and his competitive career has been finalized.

Although there is a lot of wealth, it seems to be happy! But its heart is painful!

As we all know, Ronaldo is aloof and arrogant, and I am the only one!

I take the super plum ball king as my responsibility all my life, and pursue honor, glory and data all my life.

C Ronaldo has been a technical career for more than ten years, and his money has been free and his wealth has been satisfactory; It cares more about face, scenery and honor.

During C Ronaldo’s career, during his years in Real Madrid, he won four Golden Globes and four Champions League games, which strengthened his confidence and courage, boasted himself the first, second and third place in the world, was extremely inflated and self-mad.

C Ronaldo’s greatest misfortune is to regard the platform as an ability! It is the real Madrid platform and personal efforts that have made its real Madrid years dazzling!

C Ronaldo left Real Madrid, moved to Juventus and Manchester United, accomplished nothing, and never won the Golden Globe Award, Sir, or the Champions League again! 16 lang in the Champions League every year! Its juventus years are incomplete!

C Ronaldo’s national team was ruined, and fans said that it was lying in the European Cup. Although it was exaggerated, it was not groundless!

C Ronaldo’s World Cup achievement is hands-free, which is a stain on his life! Causing 10 zeros in the World Cup to be bleak. Single-core team leader has the best score in the top 16.

After the dark years after Real Madrid, nothing was achieved after the World Cup.

C Luo Fang understands that it is the Real Madrid platform and Lafayette that have made its brilliant Real Madrid era. I mistook the Real Madrid platform for my ability, woke up like a dream, and wanted to return to Real Madrid and relive the beauty. But the vicissitudes of life, powerless, was rejected by Real Madrid! I have to go to Saudi Arabia to waste the rest of my life!

Life is like this, when you miss the opportunity, it may be a lifetime of regret and regret!
