Among them, in 2020, the platform revenue was 4.896 billion yuan (RMB, the same below), the average monthly activity of online music service was 181 million, and the online music payment rate was 8.8%.  

Netease Cloud Music was officially launched in April 2013, focusing on music discovery and sharing. Netease is the controlling shareholder of Netease Cloud Music. According to the prospectus, the revenues of Netease Cloud Music from 2018 to 2020 were 1.148 billion yuan, 2.318 billion yuan and 4.896 billion yuan respectively, with year-on-year growth of 101.9% and 111.2% respectively in the past two years. Online music service, community entertainment service and others are the two major revenues of Netease Cloud Music. With the growth of community entertainment service and other business income, its revenue is gradually diversified. In 2019, they accounted for 76.6% and 23.4% respectively, and in 2020 they accounted for 53.6% and 46.4% respectively.  

The so-called online music service can be simply understood as paying for members. From 2018 to 2020, the monthly accounts of online music services of Netease Cloud Music were 105 million, 147 million and 181 million respectively, among which the number of paid members was about 4.2 million, 8.63 million and 16 million respectively.

At the same time, deepen cooperation with various partners and further expand the diversified business model of the platform. The sponsors are BofASecurities, CICC and Credit Suisse.  

Copyright war in the first half, refined operation in the second half  

In fact, Internet companies such as Tencent, Baidu, Ali and Netease have all laid out in the music field, forming the whole industrial chain layout of online music, online karaoke, offline performances and digital albums. However, with Baidu Music being managed by Taihe Music and Xiami Music shut down, Cool Dog Music, QQ Music and Cool Me Music under Tencent Music Entertainment and Netease Cloud Music under Netease Company have become one of the few players in the online field.  

The last round of stories in the online music market originated from copyright. Due to historical reasons such as "free download", Baidu Music did not buy more music copyrights, and QQ Music, Xiami Music Music and Cool Dog Music took the opportunity to rise. Although the market did not form an absolute advantage at that time, the copyrights in their hands were enough for them to gather a group of audiences.  

The advantage of copyright has also become a key turning point in the history of Tencent’s music entertainment. In 2016, Tencent merged its QQ music business with China Music Group. Tencent replaced its equity with resources and became the largest shareholder of the newly established Tencent Music Entertainment Group. It includes three online music platforms: QQ Music, Cool Me Music and Cool Dog Music, two live broadcast platforms: Cool Dog Live and Cool Me Live, and a national karaoke platform.  

Since then, most domestic online music platforms have a certain amount of exclusive copyright, forming a situation of "one super and many strong". There are also offensive and defensive issues in copyright resale, among which Tencent Music Entertainment, which has the most exclusive copyright, and Netease Cloud Music, the "upstart", are the most fiercely contested. Tencent Music Entertainment has asked Netease Cloud Music to remove songs on the grounds of copyright three times. In 2017, when the copyright issue was the most serious, Ding Lei, CEO and director of Netease, also made a speech.  

Finally, under the mediation of the National Copyright Administration, Tencent Music Entertainment and Netease Cloud Music reached an agreement on the cooperation of online music copyright, and the two parties will authorize each other more than 99% of their exclusive music works, and agree to carry out long-term cooperation in music copyright. Earlier, Tencent Music Entertainment had reached a copyright transfer cooperation with Ali Music. In other words, with the "entry" of the National Copyright Administration, domestic mainstream music platforms have carried out several rounds of mutual authorization, and finally the copyright libraries are basically similar.  

In recent years, Netease Cloud Music has also actively reached a direct authorization with record companies. On the day when Netease released its financial report this year (May 18th), Netease Cloud Music and Sony Music reached a copyright agreement. So far, Netease Cloud Music has collected the copyrights of the three major record companies. In this regard, Ding Lei, CEO and director of Netease, said that we are very active in cooperating with various upstream content providers to help them publish high-quality music content. This has always been our goal, and we will actively cooperate with more upstream content providers in the future. In terms of IoT, whether it is a car or a smart home, it is a music playback scene that Netease Cloud cooperates very closely.  

After the copyright war died down, refined operation became the consensus of all families. There are also differences in the ways of choice. Tencent Music Entertainment has made great efforts in the fields of live broadcast, karaoke and long audio. Netease Cloud Music tried short video, live broadcast and knowledge payment, and finally found the community positioning.  

After 90% of active users are 90, change the form of traditional music products. 

According to the prospectus, in 2020, the average daily listening time of Netease Cloud Music users is 76 minutes. Users who actively create UGC account for 25%. By the end of 2020, the total number of song lists created by Netease Cloud Music users exceeded 2 billion, ranking first in China, with the highest user participation. Netease Cloud Music also keeps leading the industry in the data of per capita daily usage frequency, new user retention rate and active user retention rate.  

Relying on the positioning of music community and music discovery and sharing, Netease Cloud Music has changed the form of traditional online music products. Users’ habit of listening to songs has changed from "search mode" to "recommendation mode". According to the data in the prospectus, at present, Netease Cloud Music users have 2.8 artificial intelligence recommendations from the platform for every 10 songs they listen to on average. Innovative functions such as music criticism fully release the value of music connecting people’s emotions. 48% users of Netease Cloud Music will watch music reviews.  

According to the consulting data, Netease Cloud Music is the most popular online music platform among young users born in 1990s in China. The unique community atmosphere makes the platform popular with a large number of young users and creators, who nicknamed Netease Cloud Music "Cloud Village". According to Mob Research Institute’s "Picture Book of Generation Z College Students", Netease Cloud Music has become the most popular entertainment APP for Generation Z college students with high active users and high TGI (preference). According to the prospectus, about 90% of Netease Cloud Music’s active users are post-90 s.  

According to QuestMobile2020“Z Insight Report on "Generation Z", the online consumption ability and willingness of Generation Z (post-95 s and post-00 s) are much higher than those of the whole network users; At the same time, Generation Z is also a heavy user of mobile Internet, and its depth and breadth of use are higher than the average level of the whole network. The famous "adolescent effect" in the music market shows that the songs you listen to when you are young will affect your musical taste all your life. The music community where young users gather has more profound emotional value, which also means that the platform itself will have longer vitality.  

In addition, Netease Cloud Music also actively supports original musicians. According to the data in the prospectus, as of 2020, Netease Cloud Music has more than 230,000 original musicians, and the original musicians’ works account for 45% of the number of songs played on the platform.  

According to reports, Netease Cloud Music is the first music platform supported by original music in China. On the day of its launch in 2013, Netease Cloud Music announced that it would "create the best communication channel and space for thousands of musicians in Qian Qian, China". Since then, the platform has successively launched the industry’s first systematic musician support plan "Stone Plan", the "Ladder Plan", which pioneered many music revenue models, and the first large-scale original musician’s annual festival in China, "Hard-ground Furnace Night" and many other initiatives, which helped the original music market to keep pace with mainstream commercial music from being neglected.  

The rapid development of original music in mainland China, on the one hand, has promoted the vitality of the music market in China. The landlord’s cat, Yan Renzhong, Vicky Genie Chen and many other new generation musicians became popular from Netease Cloud Music; Various music types, such as national wind, folk songs and electronic music, have also moved from Yuncun to the whole network, from the small crowd to the public. On the other hand, as an important part of the national tide, the rising original music has also become an important carrier of cultural communication in China.

Do you still need a flu shot when you feel that you have the flu? What is the current epidemic situation of respiratory diseases? The authoritative expert answered.

  The National Health and Wellness Committee held a press conference on the 10th to introduce the prevention and treatment of respiratory diseases in winter.

  It is still recommended to vaccinate against influenza if symptoms are not diagnosed and self-healing.

  Fever, cough, runny nose … After these flu-like symptoms appear, if you don’t go to the hospital to be diagnosed with the flu, do you still need to get the flu vaccine after recovery? When is the vaccination? Xia Gang, director of the Department of Health and Immunity of the National CDC, responded to the suggestion that this situation should still be vaccinated against influenza.

  Xia Gang explained that there are two main reasons. First, the symptoms of respiratory infection are not specific, and many pathogenic infections may have flu-like symptoms such as fever and headache. However, these symptoms are not necessarily caused by influenza virus, but also by other pathogens, the most common of which is the common cold.

  Second, there are many types and subtypes of influenza virus that can cause epidemic. After being infected with a certain type or subtype, you may be at risk of being infected with other types or subtypes. For example, if you have been infected with influenza A, you may still be infected with influenza B. The influenza vaccine is a multivalent vaccine covering many different types and subtypes, that is, the commonly used trivalent and tetravalent vaccines. If you are infected with a certain type of influenza and vaccinated with influenza vaccine containing other types of influenza components, you can still play the role of vaccine in preventing this type of influenza.

  In addition, in the same epidemic season, there are usually different types and subtypes of influenza viruses co-prevalent. At present, the main subtype is influenza A (H3N2), followed by influenza B.. In the past, in the same epidemic season, the dominant strains were gradually transformed from one type to another.

  Xia Gang stressed that even if there are flu symptoms recently, it is recommended to get flu vaccine as soon as possible after recovery.

  The overall amount of diagnosis and treatment of children’s respiratory diseases in medical institutions above the second level in China showed a downward trend.

  Mi Feng, spokesperson of the National Health and Wellness Commission, said that in view of the current high incidence of respiratory diseases, especially children’s respiratory diseases, the National Health and Wellness Commission, state administration of traditional chinese medicine and the National Bureau of Disease Control and Prevention have continuously strengthened monitoring and judgment, dispatched the supply and diagnosis of medical resources in various places, guided the overall deployment of medical resources within and between medical institutions, increased relevant consulting rooms and treatment areas according to the number of patients, and expanded ward resources. Guide secondary hospitals, maternal and child health hospitals, traditional Chinese medicine hospitals, and primary medical and health institutions to "open as much as possible", extend the consultation time, optimize the in-hospital diagnosis and treatment process, improve service efficiency, and effectively protect the needs of pediatric diagnosis and treatment.

  Mi Feng introduced that at present, the overall amount of diagnosis and treatment of children’s respiratory diseases in medical institutions above the second level in China has shown a downward trend, and the increase in pediatric diagnosis and treatment in some large children’s specialist hospitals and general hospitals has been alleviated to some extent.

  Judging from the overall situation of fever clinics and emergency departments, the number of patients with respiratory diseases in China has been relatively stable in recent days, especially in primary medical institutions. The overall normal medical services in the country have not been affected.

  Mi Feng stressed that it is necessary to give full play to the role of medical associations, medical associations, medical groups and Internet medical care, establish a mechanism for collaboration between general hospitals and primary medical institutions, expert sinking and patient referral, and divide patients into different levels to facilitate patients to choose medical treatment reasonably.

  It is necessary to give full play to the characteristics and advantages of traditional Chinese medicine and combine traditional Chinese and western medicine to improve the prevention and treatment effect.

  Primary and secondary schools, kindergartens, nursing homes, social welfare homes and other key places and crowded places should implement measures such as ventilation and disinfection, strengthen health science popularization and health monitoring, do personal protection, reduce the spread of diseases and reduce the risk of infection.

  We should continue to do a good job in vaccination and constantly optimize vaccination services.

For the first time in office! Biden leaves for Europe, German media: America and Europe can’t go back to the past.

  [Special correspondent of Global Times in Germany Aoki Special correspondent of Global Times Zhen Xiang] On the 9th, US President Biden will leave for Europe to visit Britain, Belgium and Switzerland to attend the Group of Seven (G7) summit, NATO summit, US-Europe summit and US-Russia summit. China and Russia will be the key topics of Biden’s trip to Europe, according to statements made by senior NATO and EU officials on the 8th. Biden hopes to use his first foreign visit since he was elected president of the United States to prove to his allies that "the United States is back." However, many western media and experts believe that the relationship between the United States and Europe can not go back to the past.

  China and Russia will be the key topics of the G7 and NATO summits.

  According to the "Deutsche Welle" report, Biden met with visiting NATO Secretary General Stoltenberg at the White House on the 7th. The two agreed that it is essential to strengthen transatlantic relations in today’s increasingly fierce global competition. They also discussed the possibility of strengthening NATO’s strength to meet new challenges. These challenges include global terrorism, climate change and tensions with China and the Russian Federation. Stoltenberg said that he agreed with Biden’s two-track strategy toward Russia, including "deterrence, defense and dialogue". The senior NATO official said that cooperation with China can bring economic opportunities to the West, but some problems also make it difficult for NATO to develop relations with China. According to the US political news network, Stoltenberg stressed that NATO should turn its focus to China, and the joint statement issued by the NATO summit will involve more China.

  European Council President Michelle hailed "America is back" on Monday. According to Reuters’s report on the 8th, Michelle said that Biden’s trip to Europe this week marked that multilateralism "survived" after the Trump administration, which means that the EU has a very strong partner to promote the multilateral model. He predicted that the G7 Summit would discuss the need for the West to take a more active approach to defend its values in the face of "China’s rise and Russian self-confidence".

  "The United States and Europe can’t go back to the past."

  The 78-year-old Biden will have the most intense itinerary since he took office. After their departure on the 9th, he and his wife will first arrive at Milden Hole Air Force Base in the UK, where they will meet with the US Air Force stationed in the UK. On the 10th, they will visit Cornwall, England, where Biden will meet with British Prime Minister Johnson and reiterate the special relationship between the United States and Britain. From 11th to 13th, the American president will attend the G7 summit, then fly to Brussels to attend the NATO summit on 15th and have a private meeting with Turkish President Erdogan. On the 16th, Biden will travel to Switzerland to meet with Russian President Vladimir Putin.

  Agence France-Presse said on the 8th that Biden’s current visit will "guard democracy" and "hold high the banner" for western countries at a "turning point". Biden wrote in the Washington post a few days ago that the "democratic alliances and institutions" that played a great role in the last century have the ability to deal with the current threats and opponents, and this week will prove this.

  "Biden will be warmly welcomed." According to the Associated Press reported on the 8th, when Biden arrives in Europe, he will find that all the hosts welcome him. For most American allies, Biden gave them a sigh of relief. Former US President Trump often creates chaos, accusing NATO of relying on the United States and insulting the EU. In contrast, Biden emphasized his support for international diplomacy. However, European countries are also wary of the United States. Trump has left them with an indelible shadow, and there are many differences between the United States and Europe. For example, although Biden has begun to rebuild relations with NATO, Washington still hopes that other NATO members will increase their defense spending, which is Trump’s previous position.

  "The United States and Europe can’t go back to the past." Germany’s "Focus" magazine commented on the 8 th that Biden hopes to open a new transatlantic relationship, but the United States has changed and Europe also hopes to gain more "strategic autonomy." Europe is worried that there will be a Trump-style president in the United States again, and the relationship between the United States and Europe will once again be cracked. Europe hopes to strengthen cooperation with the United States in key areas such as climate, vaccines, trade and security, but it will also have its own policies on relations with China and Russia. According to Washington post, experts believe that Biden has not appointed the permanent representative of the United States to NATO and the ambassador to the European Union, which shows that Washington is indifferent to this matter. European commentators also realize that no matter how friendly Biden is in London and Brussels, the United States increasingly regards Europe as a secondary partner in its increasingly fierce competition with China.

  Will the US-Russia summit go smoothly?

  The US-Russia summit will be the highlight of Biden’s trip to Europe. Many people in the United States believe that Biden should not meet with Russian President Vladimir Putin and that this meeting is a "reward" for Moscow. According to Bloomberg News, US Presidential National Security Assistant Sullivan said on Monday that holding a summit meeting is the best way for the United States to clarify the intentions of the Russian government. The summit will give Biden the opportunity to show Putin the intentions and capabilities of the United States and Putin the intentions and capabilities of Russia. He also believes that Biden’s "participation in this meeting will be smooth."

  However, Sullivan also lowered people’s expectations of the summit results on Monday. "If you have to wait for really important results, you may have to wait for a long time, which is conceivable." On the 8th, Agence France-Presse listed five key issues that will be involved in the US-Russia summit, including election intervention, arms control and diplomatic tensions, and believed that both sides complained about each other on these issues. Before the summit, politicians of both the United States and Russia expressed pessimism about the outcome of the summit.         

  According to media reports such as the US "Axios" news network, Biden spoke with Ukrainian President Zelensky on Monday and invited him to visit the White House this summer. Zelensky had hoped to meet Biden before the US-Russia summit, but this request was rejected by Washington. As the US-Russia summit approaches, Ukraine keeps putting pressure on NATO and the United States, hoping that Kiev can join NATO as soon as possible. Stephanie Hina, Ukraine’s deputy prime minister in charge of European and Euro-Atlantic integration, said that it was NATO’s "biggest mistake" for western countries to remain silent on Ukraine’s accession to NATO, and Kiev had been expecting a "historic response" since the NATO summit in Bucharest in 2008.

Mazda CX-70 announced its overseas price, and it was powered by 3.3T

Mazda officially released the CX-70 series in the North American market at the end of January 2024. As the second combat-capable CX-70 with a vertical rear-drive chassis in the North American market, it soon appeared on the sales market. North American Mazda, in late February, announced the complete price setting on its website. The price of the 3.3-liter turbine model entering the car series starts at $40,445 (without tax), while the price of the PHEV model starts at $54,400. According to the US Mazda website, the CX-70 is currently available in a total of two power and seven models.

The more interesting part is that the price of the CX-90 has been announced for sale in February 2023, and from the current North American Mazda website, it can be seen that the price of the CX-90 series starts from $37,845 to $57,450. From the price point of view, the price of the 5-seat CX-70 series is even more expensive than the three-row seat CX-90. Is it just like the price of a two-door sports car is higher than that of a sedan? The fewer doors, the more expensive it is, and the fewer seats, the higher the price!

Of course, the less the door, the more expensive the argument is a joke, and the price setting of the 5-seat CX-70 is higher than that of the 3-row CX-90, which is also a misunderstanding. After careful comparison, it will be found that Mazda in North America has programmed the CX-90 from the entry-level Select model, followed by Preferred, Preferred Plus, Premium, Premium Plus, S, S Premium, S Premium and other models, plus 3.3T and PHEV two power unit options, the CX-90 car series has a total of 11 models.

As for the seven car series of the CX-70, the entry is the Preferred model, and it is not like the CX-90 with the Select model as the entry configuration. The entire product positioning is quite different. After further comparison, it will be found that whether it is the CX-70 or the CX-90, the price setting of the same model is exactly the same. The 3.3 T Preferred model of the CX-70 is priced at $40,445 untaxed, while the 3.3 T Preferred model of the CX-90 is also priced at $40,445 untaxed, and the rest of the models are the same.

In terms of body size, the CX-70 and the CX-90 are actually not far from each other, with a length of about 5,100mm (inclusive). The similar size highlights the difference in the original intention of the product, which also means that the main product differences between the CX-70 and the CX-90 still lie in the differentiation of interior space application and vehicle demand.

The universe we live in is just a holographic projection?

#00958C
In the past few decades, with many of us spending a lot of time online, the real world seems to have become wider. However, in one field of theoretical physics, the situation seems to be developing in the opposite direction. In the past twenty years (although this article was written in 2009, it is still worth reading), string theorists have been discussing the view that the time and space we live in, including ourselves, may be just an illusion.Holograms produced by "some reality". And this reality lacks a key feature of the world we perceive: the third dimension. Professor Juan Maldacena of Princeton Institute of Advanced Studies has played a decisive role in the development of the idea of holographic principle. In the 1990s, Marda Sina proposed the first implementation.Cosmological model of holographic principle. Recently, he was interviewed by the author during his visit to Cambridge.
The holographic principle originated from one of the biggest scientific problems in the 20th century:There is incompatibility between general relativity and quantum mechanics..
At the beginning of the twentieth century, Einstein discovered thatTime and space are inseparable.He called the structure formed by the two space-time. His general theory of relativity points out that space-time itself willDistorted by a massive objectAnd gravity is the result of this distortion. It’s like putting a billiard ball on a trampoline, which will create a depression and make the nearby marbles roll into it; Similarly, massive objects (such as planets) will bend space-time and attract nearby objects by their gravity. According to Einstein, gravity is not something that propagates through space, but is caused by the geometric structure of space-time itself.
general theory of relativityThe main description isPlanets and galaxiesThe world, and quantum mechanics mainly focuses on the subatomic scale, that is, the basic particles that make up matter. At this scale, the mass is so small that gravity can be ignored. Quantum field theory is a quantum mechanical description of particle physics, which holds that elementary particles transmit force through messenger particles called gauge bosons:One elementary particle transmits force to another particle by sending some gauge bosons..
Figure 1. Huge objects distort space-time.
In the development of the 20th century, electromagnetic force, weak nuclear force and strong nuclear force are the four basic forces.Messenger particleAre all in the experimentBe observedYes. In order to maintain theoretical consistency, Einstein’s theory should also be able to be rewritten with similar messenger particles. Physicists willGravitational messengerParticles are calledgion(graviton), but we haven’t found its trace yet. Even more frustrating, tryingUsing quantum field theory to describe graviton meetinglead toinsignificance/meaninglessThe answer. Marda Sinar said: "Simply quantizing gravity is not feasible, which will lead to mathematical inconsistency. We need something new. "
So far, a much-anticipated new quantum gravity theory has not been discovered. A strong competitor isString theory, or "string theory family"-because string theory is actually a set of logically self-consistent.A collection of theories. The core point of string theory is to put the basicParticles are regarded as tiny vibrating strings.This provides a way for us to bypass the mathematical problems in simple quantum gravity. As a mathematical theory that has attracted many theorists with its beauty, the disadvantage of string theory is that it has not been given.A complete description of the worldMany physical quantities cannot be described yet. In addition, string theory has not been verified by experiments, and it can’t be verified in fact. However, it is string theory that provides Marda Sinar with a clue to solve the mystery of quantum gravity: regard gravity as an illusion produced by quantum holograms.
Figure 2. Quantum mechanics describes the subatomic world well.
The contradiction between general relativity and quantum mechanics will not bother most practical applications. What physicists usually study isLarge-scale worldHere it is.The quantum effect is not obviousOr a small-scale world, where particles are lighter and gravity has less influence. However, in a special case, the conflict between the two theories becomes particularly obvious: when a large amount of mass is concentrated in a small area of space, a black hole will be formed.. The gravity produced by a black hole is so strong that even light cannot escape.Therefore, when studying black holes, we can’t ignore the influence of gravity. At the same time,The small scale of black holes also means the existence of quantum effects.. Therefore, in order to explain the phenomena in black holes, we really need a unified theory of quantum gravity.
Black holes are the original holographic principle.Theoretical sources. They have a boundary that cannot be returned, which is called the event horizon. Once you cross this boundary, you will be sucked into the black hole and never escape. When you fall into a black hole, a lot of information will disappear with you. This information includes not only your DNA and one or two best ideas, but also countless combinations of blood cells in your veins and all the confused thoughts in your mind. However, in the world of black holes, things look much simpler. Classical physics assumes that nothing can escape from a black hole, and thinks that a black hole can be used only.Three messagesTo fully describe:Its qualityelectric chargeandspin velocity. Therefore, when you fall into a black hole, all the information needed to describe you will be sucked into these three parameters of the black hole-your fall makes the universe a little simpler.
Figure 3. A simulated black hole with the background of the Milky Way.
This reduction in complexity usually worries physicists because it violates one of the most basic laws of physics:second law of thermodynamics. The second law of thermodynamics shows that things will never get simpler. The total amount of information needed to describe a system is measured by a physical quantity called entropy. In classical physics, entropy is defined for thermodynamic systems, such as melting ice under the sun. Classical entropy measures the degree of heat (or energy) dissipation in a system.
However, energy is related to excited atoms (in ice, water molecules are arranged in a fixed lattice in order, while in liquid water, they move around), so entropy is also a standard to measure the disorder of the system. The disorder degree of the system is related to information: the periodic arrangement of water molecules in ice crystals can be described in one sentence, but for liquid water, you need to provide the exact position of each molecule, which involves a lot of information. Therefore, entropy is related to both thermodynamics and information.
The second law of thermodynamics shows that,Entropy will never decrease.. Under thermodynamic conditions, this means that the system will strive to reach the equilibrium state of complete energy dissipation. In the context of information, this means that things will not automatically become simpler. From the classical point of view, a black hole is not a hot object, and it is very simple to describe, so there should be no entropy. When you fall into a black hole, your positive entropy will become the zero entropy of the black hole, whichViolation of the second law of thermodynamics.
When this potential problem is noticed, some physicists can only accept the fact that the second law of thermodynamics may not be as basic as we thought. However, one physicist, Jacob Bekenstein, was unwilling to give up easily. In 1972, Beckenstein discovered the relationship between entropy and the properties of black holes discovered by Stephen Hawking. Hawking has been thinking about the horizon of a black hole. The event horizon wraps a certain space volume like an egg shell-it is a surface, and you can measure its area. Hawking has proved that,The horizon will never shrink.No matter what you do or put into a black hole, the area of the horizon will only increase, just like entropy.
Figure 4. The second law of thermodynamics paves the way for the holographic principle.
This analogy with thermodynamics was initially thought to be purely coincidental, but Beckenstein put forward a controversial explanation: "Beckenstein thinks you can putThe area of event horizon is regarded as a kind of entropy., "Marda Sina explained. "The idea was not clear at first, but when Hawking discovered that black holes couldquantity of radiant energy(now known as Hawking radiation), this idea became more clear. In other words, black holes are hot objects, so they must have entropy. "By combining Beckenstein’s original idea with Hawking radiation, we can calculate that the entropy of a black hole is indeed equal to the area of a black hole measured in a certain length scale-Planck unit. Because Planck unit is very small, soEntropy of black holeIs a considerable value. Although the black hole occupies the three-dimensional volume of space, its information content seems to be a feature of its two-dimensional event horizon.
You may think that black holes are very strange things, but physicists Gairal Us’ t Hofter and Leonard Susskind went one step further, and they considered those in ordinary space areas.information content. Whether it is the pages of books, neurons in the brain or photons transmitted through optical fibers on the Internet, information exists in physical form. This physical form involves energy. Since energy is equal to mass (recall Einstein’s E = MC), compressing information into a limited area of space is equivalent to compressing mass into it. If you try to put too muchQuality/information is compressed into it.You will get a black hole, so the information content in the limited space of non-black hole is limited. Hofter and Susskind calculated this limit, and found that it is measured in the same way as a black hole, which is measured by the surface area of the regional boundary.
Marda Sina said: "This may sound very simple and naive, but in all our other descriptions of the world, variables increase with the increase of volume. For example, if we want to describe the electromagnetic field in a space, we will divide the volume into many parts and describe the electromagnetic field of each part. " If you double the size of the area, you should also double the number of partitions, so the information required for your description should also be doubled. According to this intuitive idea, information should increase with the increase of volume, not with the increase of area as described by holographic principle. If the holographic principle is correct, then the three-dimensional method of our physics is wrong. We should be able to use a simpler version of physics, one that depends on area rather than volume. This leads to a puzzling question, that is, whether the third dimension really exists, or whether it is just an illusion, just like a three-dimensional image created in a hologram.
So far, no one has found an accurate formula to describe the two-dimensional version of physics in our three-dimensional world. However, in 1995, Susskind redefined string theory centering on holographic principle. Then in 1997, Juan Marda Sinar, who was only 29 years old, put forward a concrete description of the first holographic universe in history.
Marda Sina’s universe is not completely in line with the universe we actually live in: it is amodelA "toy" universe has its own complete set of physical rules. Because all the physical phenomena that occur in it can be defined by only.Physical theory on the boundaryTo describe, so this toy universe is aholograph. More importantly, in this universe, the problem between gravity and quantum mechanics has been completely solved: the theory defined on the boundary is pure quantum, which does not contain gravity, but the creatures living in it can still feel gravity. In this universe,Gravity is only part of the hologram illusion..
In order to understand the toy world of Marda Sina, we need to understand the world of map making first. In order to show the sphere on a flat piece of paper, we need to cut the sphere and flatten it, which will inevitably introduce some distortion. In the traditional Mercator projection of the earth, this distortion is the most serious near the poles. When you look at the map, Greenland looks as big as Africa, but in fact it is more than 14 times smaller. Besides, if you project the shortest path from London to Sydney on the map, you will get a curve instead of a straight line. On a map like this,A straight line does not correspond to the shortest path..
Figure 5. Mercator projection of the earth. The red disks actually have the same area, but their different sizes on the map illustrate the distortion of the map.
MC escher’s famous woodcut "Circle Limit III" shows a two-dimensional map of Marda’s Sina universe. Similar to Mercator projection, there are some distortions here. In escher’s map, the shortest route between two points is not a straight line connecting them, but an arc intersecting with the boundary circle of a disk at right angles.
Fig. 6. The Circle Limit III by MC escher. The shortest path is shown in white.
If you use this new metric to measure the size of fish, you will find that, contrary to their appearance, they don’t get smaller and smaller as they approach the boundary circle, but they are actually equal in size. Just as travelers walking on the surface of the earth will not realize the distortion shown by Mercator projection, people living in this so-called hyperboloid world will never notice any distortion in the size of fish. More importantly, in order to reach the boundary circle, the hyperbola must pass through an infinite number of copies of fish of the same size. In other words, it will have to span an infinite distance. For hyperbola, the boundary circle is infinitely far away.
Unlike a hyperboloid map, a "real" hyperboloid can hardly be drawn because it is severely distorted. Hyperbolic surfaces have what mathematicians call negative curvature. The small area of this "plane" looks like a saddle: along one direction, they look like the peak of a ridge; In the other direction, they look like the bottom of the valley.
For external observers like us, this strange two-dimensional world has an interesting feature: although according to new metrics, theirThe scope is infinite.But we can see their boundaries-this is exactly what we need to apply the holographic principle, which describes the interior of the space area according to the boundaries. In Marda Siner’s model of the universe, he used the three-dimensional simulation of hyperboloid plus the fourth dimension of time to form a model called anti-sitter space, which was named after the Dutch physicist William de Sitter.
Anti-de Sitter space is completely different from the world we actually live in.Where time and space are distorted in strange ways, but this does not prevent us from creating a set of physical rules for it. What you need is something.basic concept, such as elementary particles and forces, and the mathematical laws describing their interaction. Marda Sinar used a version of string theory to describe the physical phenomena in his model universe. As you remember, string theory includes quantum mechanics and gravity, so creatures living in Marda Sinar’s model universe will feel gravity in a way similar to ours.
Figure 7. A holographic universe
Marda Sinar’s key discovery is that the string theory describing the interior of the universe leaves a "shadow" on the boundary of the universe: you can define a quantum field theory on the boundary, so that every elementary particle in the interior has a corresponding particle on the boundary, and every interaction between elementary particles in the interior exactly corresponds to the interaction between boundary particles. Now you can completely describe it with the theory of boundary, for example, the action of throwing an apple inside. This means that you can even completely ignore the inner world without losing any information-this world is a real hologram.
From the point of view of quantum gravity, the key point is that the boundary theory is a quantum theory of particle physics that we are very familiar with, which is very similar to the theory used to describe the process of subatomic particles in nature. They only involve small scales, so they don’t include gravity. However, the quantum theory on this boundary can completely describe the mysterious quantum gravity theory in the internal world. This is the first time that we can completely describe a quantum spacetime.
So far, Marda Sina’s modelIt’s just a model. We don’t know whether the universe we live in is a hologram, and we still don’t have a consistent quantized description of gravity applicable to our world. The assumption of negative curvature in Marda’s Sinar model is very important, but our universe shows a slight positive curvature in the observation results. Marda Sina said: "We don’t know if there is a similar description in the case of positive curvature. People are exploring various ideas, but we don’t have a complete answer yet. "
But if it turns out that the holographic principle really applies to the world we live in, what will it mean? Does this mean that we and time and space are just an illusion? "Yes, you can say that we are an illusion or an emerging phenomenon," said Marda Sina. If we live in such a universe, then we are actually an approximate description in a sense. But this is not a new concept in physics. Take the lake as an example. It looks like a well-defined surface on which insects can walk. But if you look at it with a powerful enough microscope, you will find that there are molecules moving around and there is no clearly defined surface. For time and space, the situation may be similar. It is not clearly defined in absolute sense, but we are too big to realize it. Like insects on the lake, our eyes for observing the world are too rough to reveal the true nature of time and space. Ignorance is bliss. Although it is endless fun to discuss the philosophical aspects of things, from the perspective of daily practice, weWhether you live in a hologram or not may not matter.. "
However, for Marda Sina himself, does he really believe that the holographic principle is true? He responded: "Well, I regard this idea as a model, but it is a model that gives a complete mathematical description of quantum spacetime. Therefore, we should take it seriously until someone refutes it or comes up with a better idea. "

Live broadcast of materials science | When molecular design and experimental design have AI blessing: MaXFlow artificial intelligence application is upgraded again.

Lecture topic:When molecular design and experimental design have AI blessing, the new version of MaXFlow3.6.1 material will be released.

Lecture time:Thursday, March 16th, 2023, 15:00.

Speaker:Chuangteng Technology Lecturer

Enter the live room and remember to collect it after opening it.

It takes only 2 seconds to obtain a stable 3D molecular structure?

The generation of three-dimensional conformation of molecules plays a key role in the design of small molecules in materials science, life science and other fields. Traditional methods usually need to predict the distance between atoms, the gradient of distance or the local structure such as twist angle, and then reconstruct its 3D conformation.

In MaXFlow3.6.1, the DMCG component will be launched soon. DMCG is a method to directly predict the atomic scale, that is, to directly generate the three-dimensional coordinates of molecules without considering the intermediate value. This method can adaptively combine bond and atomic information, and refine the generated conformational coordinates through continuous iteration. This method has achieved good performance on both GEOM-QM9 and GEOM-Drugs data sets.

MaXFlow3.6.1 is about to launch the online molecular 3D coordinate generation module DMCG. DMCG can directly predict the three-dimensional coordinates of each atom without providing intermediate values such as bond length and bond angle, and visualize the optimized three-dimensional structure. This method automatically extracts bond and atom information from molecular SMILES, and obtains the lowest energy conformation through iterative optimization. DMCG has achieved excellent performance on both GEOM-QM9 and GEOM-Drugs data sets, and its intrinsic properties such as band gap of the generated conformation are consistent with the real values. This method will provide an effective basis for subsequent property calculation and molecular simulation.

With it, the optimization of reaction conditions will no longer make you "bald"

In the process of preparing new materials, many reaction parameters are usually involved. In order to find the best preparation scheme and obtain the best yield, a lot of experimental verification is often needed, which brings a lot of workload to researchers and is very time-consuming and labor-intensive. How to optimize the experimental design scheme by means of AI, so that researchers can find the best scheme only through a limited number of experiments?

MaXFlow, a molecular simulation and artificial intelligence platform, integrates machine learning algorithm with experimental design (DOE), which helps researchers quickly lock the optimal interval and greatly reduces the number of verification experiments.

In MaXFlow3.6.1, EDBO component will be launched soon, which integrates Bayesian optimization algorithm. Bayesian optimization is a global optimization algorithm based on iterative response surface, which shows excellent performance in the tuning of machine learning model. In recent years, Bayesian optimization has also been applied to the chemical field. Using Bayesian optimization method in experimental design can effectively help optimize process parameters, thus realizing data-driven decision-making.

At this conference, you will also learn about MaXFlow’s rich model building functions.

With the development of science and technology, what changes will artificial intelligence bring to our lives?

With the development and application of technology, artificial intelligence has gradually entered people’s lives, and more and more enterprises and organizations have begun to use AI technology in their business. In the future, with the further development of technology, the application prospect of artificial intelligence will be broader and will become an important driving force in the digital age.

At present, artificial intelligence has been widely used in many fields, such as medical care, financial services, transportation, education, entertainment and other fields. For example, in the field of medical care, artificial intelligence can help doctors diagnose and treat diseases quickly and accurately by analyzing and processing a large number of medical data; In the field of financial services, artificial intelligence can provide customers with more personalized financial services by analyzing and processing a large number of financial data; In the field of transportation, artificial intelligence can improve the efficiency and safety of traffic management and reduce the incidence of traffic congestion through vehicle networking technology; In the field of education, artificial intelligence can provide students with more personalized learning services through intelligent teaching systems; In the field of entertainment, artificial intelligence can provide users with entertainment services that are more in line with their needs through the analysis of users’ interests and preferences.

With the continuous development and innovation of artificial intelligence technology, its application prospect will be broader. For example, artificial intelligence will be more and more widely used in smart homes, smart cities, driverless and other fields. Smart home will provide people with a more intelligent, comfortable and safe living environment through the connection and cooperation of intelligent devices; Smart cities will improve the level and efficiency of urban management and services through big data analysis and intelligent management; Unmanned driving will improve traffic safety and reduce traffic congestion through technologies such as automatic driving and intelligent navigation.

Although the application prospect of artificial intelligence is very broad, it also faces some challenges and problems in the application process. For example, issues such as data security, privacy protection, interpretability of algorithms, and the impact of artificial intelligence on the job market require the joint efforts of all parties to promote the further development of technology and applications.

The application prospect of artificial intelligence is very broad and it will play an important role in the future economic and social development. At the same time, we should also note that the application of artificial intelligence technology needs to balance the development of technology and society, taking into account issues such as data security and privacy protection, so that it can be truly used by human beings and promote human development and progress.
