This is the first photo of the black hole at the center of the Milky Way released by astronomers on May 12. Xinhua News Agency

At 21:00 on May 12, Beijing time, the Event Horizon Telescope (EHT) cooperation organization held a press conference in seven cities around the world, including Shanghai, and announced the first photo of the supermassive black hole (Sagittarius A *) at the center of the Milky Way. For the first time in human history, the true face of the center of the Milky Way has been revealed.

This black hole photo was co-organized by the Event Horizon Telescope (EHT) and "taken" through a network of radio telescopes distributed around the world. Its release gives evidence that Sagittarius A * is the black hole in the center of the Milky Way, providing valuable clues for understanding this "behemoth" that is generally believed to inhabit the center of most galaxies. Its birth opened a new chapter in human exploration of the black hole in the center of the Milky Way.

Getting to know black holes for the first time

For the mysterious and vast universe, human beings are always full of imagination, and most of them come from the most primitive curiosity of human beings. With the development of science and technology, many imaginings have become scientific predictions, and through the unremitting exploration of generations of scientists, they have further become reality.

Modern astronomy tells us that the beautiful Milky Way we see at night is actually a flat disk-shaped spiral galaxy composed of hundreds of billions of stars. And our solar system, as an ordinary member of it, revolves around the center of the Milky Way 27,000 light-years away from the center of the Milky Way.

The "Galactic Center" was located in the direction of Sagittarius, which was covered with a large amount of gas and dust. It was difficult to observe in the visible light band, and the infrared and radio bands with longer wavelengths were less affected, which became the main way to study the "Galactic Center".

In 1933, when Carl Jansky of Bell Labs published a paper announcing the discovery of radio radiation possibly originating from the center of the Milky Way galaxy, it was the first time that humans had captured radio waves in the depths of space, but scientists at the time knew nothing about the secrets behind this intense radio radiation. Over the next three decades, Jansky’s findings were not only confirmed, but also traces of intense radio radiation were found in other, more distant galaxies.

Similar findings have led theorists to make bold predictions that galaxies harbor supermassive black holes at their centers, which are sources of intense radio radiation.

Black holes are cosmic celestial bodies that make many people curious. But few people really understand this cosmic "monster".

What is a black hole? "In layman’s terms, a black hole is actually the remains of a huge star," said Qin Ruiqiang, president of the Hebei Astronomy Amateur Association.

According to the introduction, the interior of a star is constantly undergoing thermonuclear reactions. When a star ages, it uses up the fuel in the center due to thermonuclear reactions, and there is not much energy produced by the center. At this time, it can no longer bear the huge weight of the shell. Therefore, under the weight of the shell, the core begins to collapse, and matter will inexorably "march" towards the center point. At this time, a supernova explosion will occur for a long time, until finally the star forms a star with a volume close to infinity and an almost infinite density, which is a black hole.

To fly from Earth to space, a rocket needs to reach a speed of 7.9 kilometers per second. As the mass of the Earth continues to increase, its surface attractive force will also increase, and the rocket will escape the Earth at an increasing speed. When this speed reaches 300,000 kilometers per second, nothing can escape the celestial body, including light.

A black hole is this celestial object that even light cannot escape, and this region is known as the black hole’s event horizon.

Inside, no light can escape, and all matter and mass gather at the singularity at the center of the black hole, where the curvature of space-time is infinite and the attractive force is infinite. Once inside the event horizon, all the laws of physics we know about the world break down.

In 1971, astronomers Nader Lindenberg and Martin Rees first predicted that there was a supermassive black hole at the center of the Milky Way. Because of the nature of black holes, it cannot be directly observed. But as the black hole swallows other matter, it forms an accretion disk, in which a large amount of matter rotates, rubs, and warms around the black hole, making the temperature here reach millions of degrees Celsius and appear very bright.

Black holes are one of the rarest cases in the history of science, developed to the point of exhaustion as a mathematical model without any observational evidence to prove their theory correct. In the early 20th century, black holes became widely known by Einstein’s general theory of relativity, but scientists did not discover the first black hole until 1970.

Although scientists have long simulated the appearance of black holes in supercomputers, they have long hoped to take a picture of them.

Photographing a black hole

With the continuous advancement of technology, humans can finally take pictures of black holes. Scientists chose two supermassive black holes as "models".

Released this year is Sagittarius A *, the supermassive black hole at the center of the Milky Way, 27,000 light-years from Earth and more than 400 times the mass of the Sun. The black hole image released in 2019 is from the galaxy M87, which is farther and larger, 55 million light-years away from Earth and 6.50 billion times the mass of the Sun.

"People observe these two black holes from the earth, they are very small, and the apparent diameter of the ring structure is only about 40 to 50 microarc seconds." Qin Ruiqiang introduced that a microarc second is about the size of the period at the end of an article on the earth when viewed from the moon. The two black holes seem to be a "doughnut" on the surface of the moon 380,000 kilometers away from the ground.

Such a small apparent diameter challenges the angular resolution of telescopes.

"Angular resolution is a term that describes the capabilities of a telescope," Mr. Qin said. The smaller the angular resolution, the better the telescope’s ability to distinguish distant celestial bodies, and the clearer the images we can obtain.

The optical telescope is affected by the lens process and the earth’s atmosphere, and its resolution is weak. Even the 39.3-meter European Extremely Large Telescope under construction has a theoretical limit angular resolution of only 1,000 microarcseconds, which is still far from 50 microarcseconds.

Therefore, scientists thought of radio telescopes.

The aperture of a single radio telescope can reach tens of meters or even hundreds of meters. Although the resolution is much lower than that of optical telescopes of the same aperture due to its longer observation wavelength, scientists can use a VLBI (Very Long Baseline Interferometry) technology to form two or more radio telescopes into a larger aperture radio telescope, and improve the resolution by increasing the aperture.

According to reports, the black hole photos released in 2019 were also contributed by the Shanghai Tianma Telescope. It formed the East Asia VLBI Network with several stations in South Korea and Japan to conduct observations. The addition of the Tianma Telescope has improved the quality of East Asia VLBI maps by 53%.

Although Sagittarius A * is closer to Earth, photographing it is much more difficult than M87 *. The achievement was achieved by the whims of more than 300 researchers from 80 research institutions around the world.

The EHT collaboration "combined" eight radio telescopes in six geographic locations around the world to form a so-called "Event Horizon Telescope" with unprecedented sensitivity and resolution.

In 2017, the eight telescopes, which travel north to Spain and south to the South Pole, cast a "big net" at selected targets to "retrieve" massive amounts of data to give us a picture of what a black hole looks like. But the observation window left to scientists is very short, only about 10 days per year.

In addition to the limitation of observation time, photographing black holes is also extremely demanding in terms of weather conditions. "Water in the atmosphere has a significant impact on this observation band, and water affects the intensity of radio waves, which means that precipitation can interfere with observations." As a result, experts say, the eight telescopes are located in areas with high altitudes, very little rainfall and a very high probability of sunny days.

In addition, successful imaging requires all telescopes to be fully synchronized in time. During observations, each radio telescope collects and records radio wave signals from the vicinity of the target black hole, which are integrated to obtain an image of the event horizon. To ensure signal stability, the EHT uses atomic clocks to ensure that the signals it collects and records are synchronized in time.

Chi-kwan Chan, a scientist at the Steward Observatory in the United States, the Department of Astronomy and the Institute of Data Science at the University of Arizona, has described the difficulty of observing Sagittarius A * this way: "The surrounding gas is rotating around Sagittarius A * and M87 * at a high speed at almost the speed of light. It takes a few days to several weeks for the gas to circle M87 *, but for the much smaller Sagittarius A *, the gas can circle once in a few minutes. This means that as the EHT observes Sagittarius A *, the brightness and pattern of the gas surrounding the supermassive black hole are also changing rapidly over time. Taking a picture of Sagittarius A * is a bit like taking a clear picture of a puppy chasing its tail."

In the future, EHT will make a black hole "movie"

Using existing images of two black holes with masses more than 1,500 times different, scientists can further examine the attractive forces in extreme environments.

The photo of Sagittarius A * was made from a combination of many photos extracted from the EHT observation data in 2017. Since then, in 2018, 2020 and 2021, the EHT cooperation organization has not stopped the pace of observation research. Moreover, the number of EHT stations continues to increase. In 2018, three new stations were added, including the Greenland Telescope, and the coverage of the observation array was further expanded.

In future plans, more telescopes will be used to expand the EHT observation array.

In addition to the increase in the number of telescopes, starting in 2023, the EHT will conduct observations in the 0.87mm band, which will improve the resolution by nearly 50% compared to observations in the 1.3mm band under the same circumstances. Sagittarius A * and M87 * remain the most important scientific targets of the EHT collaboration, and astronomers are exploring how they change over time and studying the surrounding magnetic field.

The continued expansion of the EHT population and technological innovation will allow scientists to share more compelling astronomical photos, and even "movies" of black holes.

"Using the next-generation EHT to film such a’movie ‘of the black hole at the center of the Milky Way is the pursuit of astronomers." Some astronomers said so.

Scientists in our country have long been concerned about high-resolution black hole imaging research. In this EHT cooperation, scientists in our country actively participated in the joint promotion of early EHT international cooperation, the joint application of EHT observation time, the observation operation of the Maxwell Telescope in Hawaii, and the post-data processing and analysis.

Scientists will also aim their telescopes at other sources to make more "doughnuts," experts say, a goal that could be achieved by building space telescopes because other "doughnuts" are smaller. (Wang Ludan, Hebei Daily reporter)

In order to find a companion on the trip, some people want to find someone to share the cost of accommodation and food. This year, it is quietly popular to find a "partner" to travel together. Searching on social platforms, you can find many posts looking for "travel partners".

However, it is not easy to find a suitable "travel partner". In addition to the same time and place, it is best for both sides to have the same consumption level. In addition, if you find a "partner" carelessly, you may also encounter fraud. Professionals remind you not to trust netizens too much. Money fraud is small and personal risk is big, so be cautious.

Guo Bin, a lawyer of Guangzhou Jinqiao Baixin Law Firm, reminded that when looking for a travel partner online, you must verify the identity information of the other party, keep the corresponding chat records, transfer records and other evidence, and ask the relevant departments for help in time if you encounter illegal and criminal acts.

"Travel partner" should find people with the same frequency.

Mr. Chen from Shanghai is 25 years old and just left his job. In July, he posted in Xiaohongshu looking for "squatting male travel partners", and soon hundreds of people privately believed him.

After some consideration, Mr. Chen finally chose Lin Si (a pseudonym), a boy who is similar in age and has basically the same travel goals, and is also willing to introduce his personal basic situation to him as a "travel partner".

In early July, they embarked on a journey to Guangdong and walked through the streets of Chaozhou and Shantou.

On the last day of the trip, the two settled the accounts of the trip and shared the expenses. During the trip, the two did not disagree on the cost. The "big accounts" such as hotel room money and train tickets were basically covered by Lin Si first, and then shared equally; For "small bills" such as eating and taking a taxi, the two take turns to pay. As for the more trivial drinks, neither of them cares too much.

For Mr. Chen, this trip with his partner was very enjoyable. Besides playing, he also made friends. They kept in touch, and then Lin Si traveled to Tibet and sent him a postcard. He said that he would try to find a tourist partner to play with later.

Not everyone can find a "travel partner" smoothly. In the little red book, the reporter found that many bloggers found no results in finding a "partner".

In April this year, Ms. Chen from Guangdong and her "travel partners" broke up before they left. Ms. Chen said that after she posted a post in Xiaohongshu looking for a "partner", two qualified female college students contacted her, hoping to accompany her. However, since the May Day holiday was approaching when the three of them were together, the source of train tickets was tight, and they didn’t grab the train tickets, so the travel plan could only be stranded.

Although she failed to travel together, Ms. Chen felt that she had no regrets. In the communication, she felt that she was not consistent with the other party’s consumption view. Both partners were college students and hoped to travel in poverty. And she has worked for two years and has a certain savings. If she always has to accommodate each other on the way out, she will not be too happy if she is wronged in accommodation and food.

In the little red book, there is also a lot of content in Tucao’s "travel partner". Some bloggers spit out the "travel partner" and regarded her as a "mother", always ordering people to do things, and even "erasing zero" for themselves when sharing the expenses, which made people feel disgusted. Netizens in the comment area have said that after reading the post, they feel that the quality of "tourism partners" is mixed, and it seems that they still need to polish their eyes.

Mr. Chen, who has successful experience, suggested that looking for a "travel partner" is actually looking for a person with the same frequency. This "same frequency" not only means that the time and place of travel should be consistent, such as identity, age, personality, spending power and so on. Therefore, it is necessary to fully understand and communicate beforehand.

Someone cheated in the name of finding a partner.

With the popularity of finding "travel partners" on social platforms, a new type of fraud has emerged to defraud money in the name of finding "partners".

In early September, Ms. Zhao and a friend planned to travel to Xinjiang, so they posted on Little Red Book, asking everyone to provide some strategies for traveling to Xinjiang. Many people believed her privately after seeing it.

A woman named Honghuaer (a pseudonym) claimed to rent a business car with her friends and invited Ms. Zhao and her friends to share the expenses.

Honghuaer said that she can book a room in Kanas, but because it is the tourist season, she needs to make a full reservation. The other party asked Zhao Nvshi to transfer a deposit of 3,000 yuan. Without much thought, Ms. Zhao chose to trust the other party and let it arrange, so she transferred the deposit to the other party.

After Zhao Nvshi transferred the money, Honghuaer didn’t tell her which hotel, when and at what price, and refused to show her plane ticket to Xinjiang.

Because she has never received the reservation information from the other party, Ms. Zhao realized that she might be cheated. When looking for Honghuaer to refund the deposit, she grinded for a few days. Honghuaer only showed the record of transferring 2860 yuan to the hotel and refused to refund the deposit.

Zhao Nvshi shared his experience of being "cheated" on the Internet. Some netizens said that they had encountered a similar situation and suspected that the other party might be a "child care" in a hotel or travel agency.

Ms. Luo, a senior tour guide from Henan, told Jimu journalists that regular travel agencies would never have such a problem, at least she had never heard of such an operation. "But it is not clear whether some low-cost groups or informal tour guides will do this."

Ms. Luo told the reporter that at present, among the tour group tourists she brought, she has never met a "travel partner", and generally she travels with relatives, friends and colleagues. She cautioned against trusting hotel or travel reservations made in one’s own name. "If even a regular tour group can’t book a hotel, let alone an individual?" Ms. Luo said that travel is no better than online shopping, money is cheated less and personal risks are greater, so be cautious.

Keep your eyes open when looking for a "travel partner"

Recently, the topic of "Little Red Book Travel Partner Post is accused of being involved in pornography" was posted on Weibo Hot Search. Some netizens found that "traveling with children, all-inclusive expenses" is becoming a code word. Extremely popular journalists searched on the platform of Xiaohongshu, and found that there are indeed many accounts with "gender as male" who limit the other party’s gender to female when posting posts looking for "travel partners", and some people call them "intentional private chat".

In this regard, Xiaohongshu officially responded that the platform attaches great importance to it. At present, it has carried out a full-scale review of the notes related to the "travel partner" in the station, and has not yet located the problems reflected by the users mentioned in the article. Once the illegal content is verified, it will be dealt with seriously according to the law. At present, the warning message of "travel, safety first" has been placed on the "travel partner" search interface of Xiaohongshu.

How to protect your rights and interests when looking for a "travel partner"? Guo Bin, a lawyer of Guangzhou Jinqiao Baixin Law Firm, told Jimu journalists that recently, the financial risks that often occur in "tourism partners" include falling into consumer traps such as black travel agencies and being defrauded of property; Personal safety risks include sexual assault and other risks brought by exciting projects. Therefore, Guo Bin suggested that after confirming the "partner" online, real-name registration system should verify the identity information of the other party as much as possible. For those involving financial expenses, try to confirm them in written form such as WeChat chat and SMS. If you encounter losses or criminal acts, it is recommended to save the corresponding chat records, transfer records and other evidence at the first time and ask the relevant departments for help in time.

　　BEIJING, Beijing, August 23 (Reporter Zhang Ni) Recently, a prospective college student in Zhejiang suspected that the monthly living expenses were less than 1,200 yuan, which caused a heated discussion. Many netizens felt that "the cost of raising a college student is too high now!"

　　From reporting to school with a kettle washbasin on his back in 1980s, to now, mobile phones, laptops and iPad have become the standard for freshmen. In the past few decades, the "entrance equipment" of college students in China has undergone earth-shaking changes, and the improvement of material conditions has witnessed the development and changes of the times. However, the increasingly obvious trend of comparison in university campuses has also caused people to think.

　　Entered school in 1989

　　— — Necessary is your own lunch box.

　　In 1989, Yang Jinsong, a young man from Guiyang, was admitted to Northwest Institute of Light Industry (now Shaanxi University of Science and Technology) and went abroad to study.

　　Recalling his college days, he said with a smile: "Life at that time was extremely simple, and the necessary thing for admission was his own lunch box, because there was no public tableware in the canteen."

　　Yang Jinsong told reporters that in those days, his living expenses were provided by his family, and he sent them to 80 yuan at home for one month, mainly for eating, and a small amount was used to buy books, daily necessities, etc. Basically, there was no off-campus entertainment expenses.

　　"In memory, at that time, everyone was very frugal. In addition to learning utensils, they were unable to purchase other items. A few families with good conditions have walkmen or guitars. " Yang Jinsong said.

　　During college, Yang Jinsong and his classmates played poker as a pastime, which basically cost nothing. He and his classmates occasionally traveled around together, which was also a poor tour. There were few cameras and basically no commemorative photos.

　　"It was not popular to go out to eat in those days, because there was no money, and everyone was honestly eating the canteen. Most students usually eat 4 cents of food when they are cooking, and they dare to eat meat once a week with a little diced meat, and a piece of sauce beef costs 8 cents! "

　　In terms of learning, in those days, tapes and books were very precious to Yang Jinsong and his classmates. Everyone would cherish them and listen and read them seriously.

　　"Silly, but very real, life is very thick, and I still feel nostalgic after the aftertaste." In Yang Jinsong’s view, the biggest difference between the life of college students now and before is that the material conditions have been greatly improved, and children have little sense of thrift and early self-reliance.

　　"In our time, we basically had to stand on our own feet immediately after graduation and no longer spend money at home. In addition to the basic living expenses, you rarely get extra money for entertainment and other consumption. Every time you go home on holiday, you have to buy a hard seat ticket, which takes 30 hours. " Yang Jinsong said that hard-working exercise is particularly beneficial.

　　Entered school in 1998

　　— — The communication tool is a BP machine

　　In 1998, Li Min (pseudonym) entered a university in Zhejiang to study business administration. As a college student in the 1990s, Li Min’s college life was much more comfortable at that time. As far as she can remember, the monthly living expenses were about 800 yuan, which were mainly used for eating and dressing, and the entertainment items were very limited.

　　"We reported to school with our daily necessities at that time, and there was nothing else." Li Min recalled that at that time, mobile phones were not popular, and there were no electronic devices. After he went to college, he bought a BP machine as a communication tool. At that time, learning English was also listening to tapes, so it would be nice to have a repeater or Walkman.

　　In the late 1990s, computers were not popular in colleges and universities, and online games and social software were not popular in schools. Li Min said that at that time, he was more focused on his studies, didn’t go out to play much, and spent most of his time studying.

　　"At that time, among the living expenses given by my parents, I had to find a way to save some for buying study materials and for some exams." She recalled that in college, students’ living expenses were basically provided by their families. Few people worked part-time to earn money, and there were few opportunities, and everyone didn’t have that consciousness.

　　In Li Min’s view, the comparison atmosphere in the school was not obvious. Students didn’t rush to pursue something, and life was simple.

　　Entered school in 2003

　　— — 10 yuan money can be eaten well in the canteen every day.

　　In 2003, Li Honghan entered Zhengzhou University to study. Recalling the scene of going to college more than ten years ago, he told reporters that many students around him were still relatively poor.

　　"Eating in the canteen is also very cheap. You can eat well for less than 10 yuan a day, plus the extra expenses of buying daily necessities. At that time, the living expenses of four or five hundred yuan a month will be enough." Li Honghan said that when he was at school, he could still receive a state subsidy of 50 to 60 yuan every month. In those days, the money was not too small, and he was very happy every time he handed it out.

　　"When I first went to college, mobile phones were not fully popular, and there were no smart phones. I remember that my first mobile phone was bought in 2007, and it was a Nokia bar phone." Li Honghan recalled that when he first entered school, everyone bought calling cards and contacted family and friends by telephone. The monthly communication expenses were not much.

　　"At that time, there was very little human expenditure, because everyone was a poor student. I felt very happy to have a meal together in the canteen. I didn’t say that I would go out every day. You invited me to invite you. Although I was poor, I was also very happy. This is our true life portrayal at that time." Li Honghan said.

　　When he was in college, Li Honghan’s first extra income was the money he earned as a tutor in his senior year. He was good at writing, and since then he has contributed to many newspapers and magazines, earning remuneration for his contribution. Although his income seems to be not much now, it was enough to make him feel excited and happy as a student at that time.

　　"I have been educated since childhood to be sensible and obedient as much as possible, and not to add too much burden to my parents, so I have always lived within my means and will not reach out to my parents in pursuit of some material enjoyment." Li Honghan said.

　　Admission in 2014

　　— — College students use Apple mobile phones.

　　Wang Jiazhen, born in 1996, entered the journalism major of Suzhou University three years ago. As a "post-95" college student, the living and learning conditions of Wang Jiazhen and his classmates have changed greatly.

　　At the beginning of her freshman year, Wang Jiazhen’s parents bought her a mobile phone and a computer, which are common among her classmates at present.

　　Wang Jiazhen said that his monthly living expenses are about 1,500 to 2,000 yuan, which is the average level in the class. "Eating accounts for the most of these expenses, and it costs about six or seven hundred yuan a month. The rest of the expenses include transportation, telephone bills, clothes and so on."

　　She told reporters that in addition to the necessary expenses for food and clothing, college students nowadays also have some personal expenses. Students occasionally eat out, and many students who are in love even send gifts to each other on festivals such as Chinese Valentine’s Day and Valentine’s Day. She quipped: "Students who are not in love at this time can save a lot of money!"

　　In Wang Jiazhen’s view, in the past few years, I have also felt that the comparison atmosphere in the school is relatively heavy. Everyone likes to compare the quality of mobile phones and cosmetics, and many people have used Apple phones.

　　"In fact, I think this should be based on personal needs. Not everything is the most expensive, so it is best. You can choose something better if you have the conditions, but you should do what you can." Wang Jiazhen told reporters that she will also earn money through part-time jobs now, and if there is something that needs to be bought, she should talk to her parents as little as possible.

　　"Nowadays, there are many opportunities for college students to work outside. I have done a lot myself, including training institution teachers, moderators, recording, etc. The school will also have scholarships. It is not a small income to save one." Wang Jiazhen told reporters that in recent years, she has also gained something through her own efforts. Now she has exchanged the money she earned for a computer and an Apple mobile phone, and bought a micro-single for completing professional homework, which makes her feel very fulfilled.

In the past year, many netizens have been there.The style of tucao costume idol drama is getting more and more lame.It is far less beautiful than the costume dramas of the 1980s and 1990s. No, at the beginning of the new year, when I saw this topic so interesting, bloggers immediately stood up.Taking stock of the main styles of men and women in costume idol dramas to be broadcast.

Among them, among the heroines, at first glance,In The Queen Liu Heipang, played by Yoko Spicy Eye, Liu Tianfeng is the most eye-catching.. The drama mainly tells the story that Liu Jinfeng, a flower from Xianpa village, made a mockery everywhere after she married into the palace, which led to the emperor being laughed at everywhere, but in the end, the "misfit" couple experienced another disaster and started a happy story.

With such a detached plot, the shape is naturally unique, coupled with the rich and clever expression of Yoko Spicy, so that everyone can lock it in an instant.

Yoko spicy eye can be seen by everyone at a glance, not simply because her style is really excellent and unique.It’s that Yoko Ayako is a different existence from other actresses, and now she is favored by people with great potential.

So, the reason why she has the potential to explode,To deus ex, mainly rely on the following aspects.

First, "non-mainstream" appearance, refusing appearance anxiety

In theory,Yoko Lamu has no facial features that strictly belong to the traditional aesthetic standards of China people.. The round fleshy face is covered with dense freckles, small eyes, and a nose that is not quite upturned. The only thing that stands out is that the mouth is still a small cherry mouth. What do all the female stars look like? Just follow the facial features of Yoko spicy eyes in the opposite direction, that is, beauty.

With the popularization of mass media, girls are looking at glamorous female stars and demanding more and more about their appearance.Appearance anxiety is getting worse.It also caused the mobile phone P-picture and the medical beauty industry to triumph all the way.

With such five senses, how does Yoko Spicy Eye treat the camera in this era? Self-confident, generous, overflowing, no stage fright.

When she was in high school, she wrote a shocking sentence in her diary: "I am not beautiful, but this one is out of print." A woman who has a clear understanding of herself before she is a minor,Refusing to "go along with the current aesthetics", Yoko Spicy has kept this mentality and played it to the present..

Second, the acting skills have emerged, and there is no sense of disobedience in Gu Li

In the hit variety "Actor in Place 2", Yoko Spicy challenged to play the role of Gu Li. Who is Gu Li’s character? Everyone is too familiar. Flashy and mean, delicate and fragile, the drama is gorgeous. After the film and television, the role of Gu Li was well recreated by Jing M.Guo, the original author of the novel, and the accent blessing of Guo Caijie Taiwanese accent. I’m afraid looking at the entertainment circle,I can’t find another actress who can challenge Gu Li.

However, Yoko spicy eyes became!

A female artist who at first glance had nothing to do with Gu Li’s setting, used a short scene to put the audience into the plot 360 degrees, and soon went out on the hot search.

Netizens are amazed and think that this actress is too powerful. In fact, as early as the first scene of Yoko Ramo’s performance "The Thief Family",Er Dongsheng directly decided that she would win the best actress in the future.With such high recognition from the great director, her future is very promising.

Third, contact Bole and connect with Shen Teng.

In the Golden Rooster Awards just past,Shen Teng and three other main pillars in Mahua FunAge recommended Yoko Ramo in the "Best Selection Plan for Young Actors in the Stars and Seas in 2021".

Yoko Ramo became attached to them in Me and My Father. In the unit directed by Shen Teng, Yoko Ramo played the role of the head teacher, which was not much, but in this regard, she hooked up with a group of actors in Mahua FunAge. Only when Yoko Mori has done well himself can he be appreciated by the Mahua FunAge team.

Fourth, diversification of resources, Disney dubbing+reality show

About to meet the audienceThe Chinese version of Disney’s latest masterpiece "Magic Room Full" will be dubbed by Yoko Ramo.. In the past, in order to match their princess phenomenon, Disney’s female stars were all popular young Hua Dan, but now they have also thrown olive branches on Yoko Spicy.

Not only that, in the reality show with the lowest threshold, Yoko Spicy appears frequently. I can’t forget the farm, Fifty Kilometers of Peach Blossom House and so on.

For many years, women who are ugly and confident at the same time can only be defined as comedians in the entertainment circle. I hope that Yoko Mori can get a completely different new image as an actress by virtue of her excellent acting skills.

　　According to 21st century business herald, the reporter noted that the Tianjin Municipal People’s Government issued the "Proposal on Further Promoting the Construction of Financial Innovation Operation Demonstration Zone" on January 8. The plan points out the overall goal of the future in three time periods: in the next three years, it will continue to maintain the leading position in the financial leasing and commercial factoring industries in China, and at the same time create a number of financial agglomeration symbol areas with themes and characteristics. In the next five years, the added value of the financial industry will account for about 15% of the regional GDP, and the overall asset scale of leasing will reach 2.7 trillion yuan. The scale of leasing and disposal of aircraft, international shipping vessels and offshore platforms will remain above 80% in the whole country, and the total assets and factoring financing balance of the commercial factoring industry will remain the first in the country. In 2035, a world-class national leasing innovation demonstration zone and a national commercial factoring capital will be built in an all-round way, which will provide a practical sample for China’s characteristic financial development.

As a commentator, Mr. Huang appeared on XXTV-5 in the early 1990s, and Huang and Liu and Zhang Sanjianke created the column of World Football, which made us look forward to every Monday when we were studying in Beijing. My last impression was that I co-hosted the 2002 Japan-Korea World Cup with Shen Bing in 2002.

Later, it is said that he joined the media and became the online celebrity of football. With his football level, he should be able to dominate one side, and entertainment football can flourish off the court. Should be blessed, although the age difference is not big, but after all, watching his program has a beard.

Another master’s corner, I really don’t know. I know it by chance because of a technical term of "protective response" That is, online celebrity, who wears sunglasses and bobs his head to catch and scold anyone on the Internet, is said to know the way and know the king better than the beautiful country and Sichuan.

Because of the big sunglasses, I knew that I had a football teenager. Frankly speaking, we are not football professionals. Although big sunglasses preached everywhere that he was engaged in youth training, we always felt that it was at best a football training class and an off-campus training class.

It seems that the relationship between the two is not bad, and they have been entertaining to death, and they are also connected to each other live. I don’t know about it recently, maybe Mr. Huang has seen through the scam; Perhaps the head of the new Football Association named the big sunglasses, and Mr. Huang wanted to raise his arms and shout for the sake of his inner conscience.

Mr. Huang finally decided that junior football is a performance class in online celebrity. Zhan Yan, it’s worse than us, and we also evaluate it as teaching and training.

Big sunglasses know the king, how can you stop? Come on, bully me, no way. Although we are not studying literature, we are studying inorganic materials. We’re not subtle. What do you think you came from? Leave that station, you’re nothing, and you’re a bitch.

Football in China, what is this situation? In a rural phrase, that is: dogs eat dog bones.

China football, when can you get clean and let a certain line really "do it"?

This time, I am optimistic about Mr. Huang, just because I follow my heart and my heart.

Generative AI is getting more and more popular. Is this really a good business?

Recently, AI painting is on fire.

By inputting some words, AI can generate an image that matches the words in a few seconds. These images are wild, and some are even bizarre. For example, people have extra fingers on their hands, and their fingers bend unnaturally. Even, AI can generate some meaningless billboards and alphabets that humans have never seen before.

Although AI painting is outrageous, it has set off a wave of science and technology: the spring of generative AI has come.

David Beisel, a venture capitalist at NextView Ventures, said that in the past three months, the word "generative AI" once became a hot word. Moreover, the generative AI technology has developed rapidly and the market enthusiasm is so high that many people even quit their jobs to start a business in this field.

There is no doubt that AI has been in a prosperous stage in the past five years or so, but most of these past advances have to do with understanding the existing data-for example, the AI model has been able to quickly and efficiently identify whether there are only cats in your mobile phone photos. However, the generative AI model generates something completely new that has never been seen before. In other words, generative AI is not just about analyzing existing data, but creating.

Boris Dayma, founder of Craiyon generative AI, believes that "generative AI is not only creating old images, but also creating many new things, which are completely different from what we have seen before."

Sequoia Capital also said in a blog post on its website: "Generative AI has the potential to create trillions of dollars in economic value." Sequoia Capital predicts that generative AI may change all industries that require human beings to create original works, from games to advertising to the legal profession. It is worth mentioning that Sequoia Capital also pointed out in its blog post that this message was partly written by GPT-3 (GPT-3 is a generative AI capable of generating text).

Working principle of generative AI

In the past, deep learning technology was widely used to train the model on large data sets. When the program understands the relationships in these data, the model can be applied to actual scenes, such as identifying whether there is a dog in a picture or translating text, and so on.

The working principle of the image generator is to reverse this process. For example, instead of translating English into French, it translates English phrases into images. Specifically, it usually has two main parts, one is to process initial phrases, and the other is to convert data into images.

At first, generative AI was based on a method called GAN, that is, the generative adversarial network. In essence, this method is to make two artificial intelligence models compete with each other to better create images that meet the target.

At present, generative AI is usually based on Transformer, such as image generator DALL-E and so on. DALL-E was first created by OpenAI in 2021, and in 2022, OpenAI released DALL-E 2.

Christian Cantrell, a developer who focuses on generative AI, said: "With DALL-E 2, we can really cross uncanny valley." (The Valley of Terror theory is a hypothesis about human perception of robots and non-human objects. It was put forward by Japanese robot expert Masahiro Mori in 1970. )

Another commonly used AI-based image generator is Craiyon (formerly known as DALL-E Mini), where users can enter phrases in the browser and see the illustrations it generates within a few minutes.

According to Dayma, since its launch in July 2021, Craiyon has produced about 10 million unprecedented pictures every day, which adds up to 1 billion. Earlier this year, the use of Crayon soared, and Dayma also took Crayon as its full-time job. In addition, Dayma has created a Twitter account to post the weirdest and most creative pictures generated by Craiyon. For example, ketchup comes out of the tap on the Italian sink.

In addition, Stable Diffusion has also received wide attention. The project was released in August this year and has been open source on GitHub. Developers can run the project on computers, not just in the cloud or through programming interfaces. For example, Stable Diffusion can be integrated into Adobe Photoshop by plug-in, allowing users to generate backgrounds and other parts of images, and use layers and other Photoshop tools to operate in applications.

Cantrell, the developer of the plug-in, said, "I want to meet these creative professionals, so that they can introduce artificial intelligence into their creative work, instead of destroying their work."

It is understood that Cantrell has worked for Adobe for 20 years. After leaving in 2022, Cantrell focused on the direction of generative AI. Cantrell said that Stable Diffusion has been downloaded tens of thousands of times, and artists told him that they used this plug-in in many unexpected places, such as making Godzilla animation or creating pictures of Spider-Man.

Start-up companies get together

Some investors regard generative AI as a potentially transformative change, just like the early development of smart phones or the Internet. This kind of transformation has greatly expanded the potential market of this technology.

"Before that, artificial intelligence was not unprecedented. Before 2007, we were not without mobile devices, "said Beisel, a seed investor." But at this moment, everything came together. The final consumer can experience and see something different from before. "

Cantrell believes that machine learning is similar to a more basic technology: database. "Machine learning is a bit like a database, which opens up a whole new world for network applications. All the applications we have used in our life are built on the database. But no one cares about how the database works. People only know how to use it. "

Michael Dempsey, managing partner of Compound VC, said that in the past, it was "very rare" for laboratory technology to enter the mainstream, but at present, generative AI has attracted wide attention of venture capitalists. Nevertheless, he warned that the current generative AI may be in the "curious stage" near the peak of the hype cycle, and the companies established at this stage may fail because they don’t focus on the specific uses that enterprises or consumers are willing to pay for.

Others in the industry believe that startups that can apply new technologies such as generative AI today may challenge technology giants such as Google, Meta and Microsoft in the future.

At present, many companies applying generative AI technology have already received large amount of financing, and their valuations have also risen. For example, earlier this year, Hugging Face was valued at $2 billion after receiving investments including Lux Capital and Sequoia Capital; OpenAI has also received more than $1 billion from Microsoft and Khosla Ventures.

In addition, according to Forbes, Stability AI, the developer of Stable Diffusion, is negotiating with investment institutions to raise up to $1 billion in venture capital.

Cloud vendors and chip vendors will benefit.

Besides start-ups, cloud service providers such as Amazon, Microsoft and Google can also benefit from it, because generative AI may require a huge amount of computation.

Meta and Google have also taken action and started recruiting talents. In September of this year, Meta released an artificial intelligence application called "Make-A-Video", which can generate videos, which makes the generative AI technology a step further.

"This is a great progress," Zuckerberg, CEO of Meta, posted on his Facebook page. "It is much more difficult to generate videos than photos, because besides correctly generating each pixel, the system must also predict how they will change over time."

Recently, Google matched with Meta and released a program code called Phenaki, which can also convert text into video and generate several minutes of footage.

This craze may also boost chip manufacturers such as Nvidia, AMD and Intel, because the advanced graphics processors produced by these companies are ideal for training and deploying artificial intelligence models.

At a recent meeting, Huang Renxun, CEO of Nvidia, emphasized that generative AI is the key use of the company’s latest chip, and he said that this kind of program may "revolutionize communication" soon.

At present, there are not many uses of generative AI that can generate commercial benefits. Many exciting breakthroughs today come from free or low-cost experiments. For example, some writers have tried to use image generator to generate images for articles. An example of Nvidia is to use a model to generate new 3D images, including people, animals, vehicles or furniture, which can be filled into the virtual game world.

Ethical issues can not be ignored.

While generating AI excites the industry, the ethical issues it brings are also worthy of attention.

The first is employment. Compared with professional illustrators, generative AI is obviously cheaper. Therefore, generative AI is likely to rob artists, video producers and other people engaged in creative work of their "rice bowls".

In addition, there are complex problems in originality and ownership of the content created by generative AI.

Generated AI is trained on a large number of images. Therefore, it is still controversial whether the creator of the original image has copyright requirements for the generated new image.

Some time ago, an artist won an art competition in Colorado, and his winning image was created by a generative AI named MidJourney. After winning, the artist said in an interview that he selected one image from hundreds of images generated by himself and post-processed it in Photoshop.

It is worth mentioning that some images generated by Stable Diffusion are watermarked, which indicates that some of the original data sets are copyrighted. Previously, Getty Images (a picture trading company based in Seattle, USA) announced that it was forbidden for users to upload generated AI pictures to its picture library, because the company was worried that there might be some copyright problems in such pictures. .

With the improvement of image generation software, generative AI may also deceive users, make them believe false information, or display images or videos of events that never happened.

In addition, developers must also deal with the possibility that models trained on a large amount of data may have biases related to gender, race or culture contained in the data, which may cause the models to show such biases in their outputs.
