You can also get a limited number of children’s membership annual cards when purchasing. You deserve it.

When I was a tour guide, I accidentally knew the truth of my life experience. Shi Ban Yu, who lives behind Zhou Xingchi, is the king

In mainland China, many people may hear Shi Ban Yu’s name, and the first reaction is Zhou Xingchi’s royal voice. In fact, long before Zhou Xingchi’s fire, steamed grouper was a specialty food in Taiwan in our country. Choosing this as his stage name, on the one hand, expresses Shi Ban Yu’s hometown feelings, and on the other hand, it is inseparable from his life experience.

Shi Ban Yu’s original name was Shi Renmao, and he was originally a recording engineer for a radio variety show. At that time, it seemed like an iron rice bowl. The TV station had regulations that it was not allowed to take private work outside. In order to prevent people around him from knowing that he was dubbing movies and TV dramas, Shi Ban Yu specially changed his name.

In fact, when it comes to Shi Ban Yu’s dubbing journey, it comes from this work experience in the radio station. The recording engineer is always a behind-the-scenes worker, requiring equipment debugging and countless contacts. Shi Ban Yu was very envious of the hosts who could be in front of the stage at that time.

It was not until 1985 that Shi Banyu studied with Chen Mingyang, who was known as the "dubbing emperor of Taiwan", that he entered the Tao. Chen Mingyang has many representative works, the most famous being Fat Cat Zheng Zeshi and Big Silly Cheng Kui’an, who arranged the dubbing of almost all their films.

The development of Master’s career was invisible, and it also affected Shi Ban Yu’s life. To this day, Shi Ban Yu and Zhou Xingchi are still the perfect partner in the eyes of the audience.

And when it comes to Shi Ban Yu and Zhou Xingchi’s karmic relationship, it is a coincidence in 1990. At that time, Andy Lau and Zhou Xingchi co-filmed the movie "Gambler". In order to find a voice actor who could be far different from Andy Lau’s screen voice, the production company Insein Company found Shi Ban Yu, a Taiwanese voice actor.

Shi Ban Yu’s personal voice was rather sharp, and before meeting Zhou Xingchi, it was always a small regret that he couldn’t cooperate with most actors. Before that, most of the dubbing was for some villains, such as eunuchs, traitors, etc. After Zhou Xingchi appeared, this kind of nonsense and a little strange voice got its use, and the dubbing Shi Ban Yu really became a king who used his voice to conquer the world.

When watching Stephen Chow’s films, many viewers were thinking that Stephen Chow and his voice actor Shi Ban Yu must have a very good relationship, otherwise how could there be such a close cooperation. In fact, the cooperation model between them is not as everyone thinks.

Generally speaking, it is Zhou Xingchi who prepares a Cantonese version of the work in advance, and then Shi Ban Yu reinterprets it in private with the other party’s performance. In particular, there are many languages in Cantonese that cannot be translated in Mandarin, which requires Shi Ban Yu to replace these words with a mouth shape and to be able to match Zhou Xingchi’s performance style.

It is worth mentioning that in movies, Stephen Chow and Wu Mengda are always a pair. In real life, the same is true for their royal voice actors Shi Ban Yu and Hu Licheng. Their cooperation has achieved a seamless integration of sound and form, and together they have created one classic image after another in the film works.

In addition to voicing Stephen Chow’s films, Mr. Shih has also worked sporadically for other actors, notably Chen Xiaochun in "The Confused 4," Jacky Cheung in "Rat’s Gall" and Tony Leung in "The Three Heroes of the Wind and Dust."

Dubbing actors are different from those in front of the screen. Although Shi Ban Yu has dubbed many film and television works, his income is still relatively small. In 2008, Shi Ban Yu started working as a tour guide with tour groups, just when he happened to meet his brother’s divorced wife during a work trip. It turned out that Shi Ban Yu was adopted by his adoptive parents shortly after birth, and he never knew his true background, but he did not expect the truth to come so suddenly.

Mr. Shi is rarely active in front of the stage, but in 2017 he made a rare appearance on a variety show called "Happy Comedian." In this episode, he teamed up with comedy genius Huang Cailun to bring a feast of performances, bringing many of Stephen Chow’s classic clips to the screen again.

It is difficult to say whether Zhou Xingchi achieved Shi Ban Yu or Shi Ban Yu achieved Zhou Xingchi. It is certain that mutual achievements have promoted each other’s development.

Ruan Jingtian exposes "shy" scenes in new drama, promises military service early next year


Ethan Ruan

    Ruan Jingtian is currently rushing to shoot Niu Chengze’s new drama "LOVE" and attended the car dealer endorsement event on the 8th. Ruan Jingtian revealed that there are many challenges in "LOVE" that he has never had before. He mentioned that there are many shy scenes in the play. When asked how shy he ****** it naked, or is it front and back? He pretended to be stupid and said: "I didn’t say anything." Then ask if he is with Chen Yanxi? He laughed and said: "No! I will know when the promotional video comes out."

    Ruan Jingtian is serving as the ambassador of the Golden Horse Awards this year. He recently took the Golden Horse Awards image advertisement to play against the little girl. He directly said that the little girl is very cute and has thick eyebrows that look like him, but he has no way of crying about the little girl. With the first experience of his father, he asked him if he wants a boy or a girl when he has a child in the future? He replied: "Girls! I like my daughter." Does it matter if the daughter is like a father? He replied: "I think I am very beautiful when I dress as a girl!" He also said that his daughter will be called "Ruan Mianmian" in the future, laughing at everyone. As for when he wants to get married? He was about to blurt out "three…", but he shrank back and said with a smile: "I can’t tell you the time, the pressure will be very high, and it will be counted down." Ruan Jingtian expressed the hope that it would not be too late and wanted to grow up with his children.

    Recently, major schools have opened one after another. Today, the media reported that Mingdao University had studied for 11 years and asked him if he knew about it? Ruan Jingtian said: "It’s hard not to see it, but it’s also hard to comment on other people’s affairs." Some media asked him if he didn’t come to school to choose courses on the opening day? He replied unhappily: "I haven’t started school yet." Then asked if he didn’t choose courses? He said: "I didn’t finish choosing courses until the 17th." He even told the media that he could go to the school for verification. He was asked about military service again, and Ruan Jingtian also promised to wait until the filming and promotion of "LOVE" was completed. It is expected that he will join the army in January and February next year.

Chen He and his wife Xu Jing are going to remarry? Reveal the top ten bloody events of Chen He’s divorce

Chen He

Stories of former lovers in the entertainment industry are frequent, and dramas such as turning against each other, catching rape, and scolding each other are staged one after another, but in terms of dog blood and excitement, they are far inferior to the Chen He divorce incident, and even the marathon-like "double yellow wrangling war" has been turned into slag in seconds. All kinds of revelations have emerged on the Internet, and of course, there are still some to be confirmed. Let’s put aside the truth or falsehood, let’s sort through one or two first, and everyone will take a look first.

Event one:When did you get divorced? Did you leave? Really leave or leave? It’s all Rashomon

In the whole incident, the most unpredictable estimate is Chen He’s so-called "divorce". When will the divorce be, whether the divorce will be completed, whether it will be a real divorce or a fake divorce, and it is still Rashengmen to this day. From the first time he was kicked out by netizens and divorced, then Chen He announced his divorce in August last year, and it was not until November last year that the divorce was agreed.They are still in an undivorced state,Then there is the "fake divorce" with his wife…It’s really confusing.

According to the inference of Mr. Huang, the person in charge of the "National talent scouting" app, Chen He and Zhang Zixuan only agreed to divorce with his wife after they fell in love with each other in November and December last year, not half a year ago as he said. Someone also told Mr. Huang that Chen He and his wife had a fake divorce at all, because he knew they were filmed.Do not sayleaveMarriage, then the result is infidelity within marriage"If you divorce in August according to what Chen He said, the relationship between the two people should still be at a freezing point at that time. It is impossible to publish a book and show their love on a show. The acting is too good, and it is not in line with human nature. So the time point in November and December is more believable. At that time, he and Zhang Zixuan were in love again."

Event two:If you want to play remarriage before you get divorced, the man agrees that the woman should consider it.

It was still unknown whether the divorce would be completed or not. There were rumors that a high-level official within Huayi had come forward today to help Chen He and Xu Jing remarry. The man actually agreed, but in comparison, the woman’s attitude was relatively cold.

Event three:Chen Heman Airport ran after the photographer and wanted to buy candid photos with money

As early as November 3 last year, Chen He and Zhang Zixuan returned to Beijing together after filming "The Laughing Biography of the Hospital" in Hengdian, and a studio photographer took a photo of Chen He. At first, the reporter did not find the identity of the heroine, and did not want Chen He to find out that the alarm bell was loud after being photographed, and he actually chased the photographer all over the airport. When the reporter saw the photo, he knew that Zhang Zixuan was actually photographed. Of course, Chen He was very polite when he found the reporter and asked why he wanted to shoot him. Later, the male and female protagonists also approached their public relations, hoping to solve the problem with money. Unfortunately, they were all rejected by them.

Looking back at the moment of Chen He Xu Jing's love v

Event four:The wife of the incident, Xu Jing, is 8 months pregnant and will give birth next month!

It is said that as early as the end of last year, some netizens broke the news that Chen He’s wife Xu Jing was 8 months pregnant.The due date is February this year.But in July last year, the couple also recorded the reality show "True Love is Lost". According to the revelations, Xu Jing was three months pregnant at that time, and the fetus was still unstable, but the show required the couple to travel outdoors together, and the degree of fatigue could be imagined. Therefore, whether Chen He’s wife Xu Jing is pregnant, whether she recorded the show during her pregnancy, and whether the due date is February this yearTo be verified

Event five:Chen He choked up and apologized to fans: I really hope you are all happy!

With more and more insider revelations, Chen He’s image as a good man in the hearts of fans was on the verge of disillusionment. It was said that at this critical juncture, Chen He uploaded an apology voice to the fan group, saying that he was really sorry for everyone, "I really hope each of you is happy and happy, I have let each of you downAlthough the recording was not long, Chen He’s tone was emotional, and his tears were touching. Some fans were very distressed after listening to Chen He’s apology with crying sounds, and called on the outside world not to hurt Chen He again, and not to comment rashly.

Event 6:Zhang Zixuan’s husband was detained for fighting and said he wanted to settle accounts with Chen He

Of course, the story of the heroine Zhang Zixuan is still exciting. According to netizens, her husbandYang Yiliu is a genius from BeiguangHe has written many TV series and movie scripts, and has been favored by many readers for his novel "Finding the Perfect World", and has also received high praise from Haiyan.This person is also a good hand in businessHe has run a clothing store, run a red hotel, and worked as a producer. However, according to Mr. Huang, the head of the "National Star Detective" app, Zhang Zixuan has not yet divorced, and her husband Yang Yiliu has been detained for fighting with others. I don’t know how long he has been detained and whether he has come out.But people have already said that they want to settle accounts with Chen He

Event seven:Both the male and female protagonists are absent from the release of the new drama, originally because they are afraid that Xu Jing will come to the trouble

Time to go back to the day of this fryer, when Chen He and Zhang Zixuan’s "Medical Museum Smile Biography" held a press conference in Anhui. But surprisingly, as the lead actorBoth are absentSo much so that after the incident, some reporters questioned whether this was a "foreplay hype" of a TV drama. In this regard, the whistleblower, Mr. S, revealed that the reason why Chen He and the others did not go to the scene should be that they were afraid that their daughter-in-law would find someone to make trouble. He even deduced that Xu Jing was the "mastermind behind the scenes". "In fact, Chen He kept this matter very secret, and many people didn’t know it. Today, someone suddenly broke the news on Weibo, probably also Xu Jing."

Reviewing the moment of Chen He Xu Jing's love

Event 8:Fans advised Chen Hehui to "run man" and were abused by fans

Earlier, it was reported that Chen He would continue to participate in the recording of the second season of "Run! Brothers". When his Weibo post admitted the divorce, a user named "Soft Persimmon Jampasg" left a message: "You can quit the positive energy show Running Man, I won’t scold you, but quit the show, okay?" Chen He immediately replied: "Okay, sorry."Crazy fans by Chen HeFlesh abuse

Event 9:Who betrayed Chen He? Who is the male artist surnamed Wang?

The source of this divorce incident was not initially captured by the media or paparazzi, but ratherThis topic was initiated on Weibo and WeChatThe industry said there was reason to suspect that it should be someone around Chen He who took him "Betray"Yes. The whistleblower also claimed to have exposed the inner circle of the Chen He incidentMale artist surnamed WangThe identity of the person is also thought-provoking,Wang Chuanjun,Wang ZulanandWang BaoqiangAll three were accused of being very suspicious. Chen Lizhi, a veteran in the circle, also suggested that Chen He was "thrown dirty water" by his friends, writing on Weibo: "The so-called brother is when he sees that you are more popular than him, he digs a hole and buries you with more false information in the semi-real. You ask the media to break the news and pay to use the marketing account, aren’t you afraid of being dug up?? "

Event 10:Zhang Zixuan’s bold photo was taken, and Xu Jing praised it "slippery"?

Whether Xu Jing and Zhang Zixuan have had a head-to-head confrontation is still unknown, but it is worth pondering that recently, the netizens "Entertainment Circle Revealed" took out a group of old photos of Zhang Zixuan and wrote: "Zhang Zixuan’s old photos were taken out. It is said that this woman has dated seven boyfriends, the first is Wang Ziyi; the second is Bai Jun; the third is Gu Nan, a small boss; the fourth is Zhao Ming; the fifth is an unknown male model, and it is said that he has also done a flow of people for him; the sixth is his former husband Yang Yiliu; the seventh is Chen He. Zhang Zixuan comes from the circle of young models, which is said to be mostly peripheral women, that is, business partners. It was also rumored that Zhang Zixuan had also interfered in the article Ma Yili Weibo… "Later, careful netizens found that Chen He’s ex-wife Xu Jing praised the Weibo" Secret of the Entertainment Industry ". Many netizens speculated whether this Xu Jing was" slipping "or did it on purpose?

Tong Mengshi’s "Qingyu Nian 2" finale, the perfect transformation of Wuzhu attracts the audience

 As the youngest of Fan Xian’s six fathers, Tong Mengshi played Wuzhu, and audiences have been eagerly anticipating his appearance since the broadcast of "Qingyu Nian 2". According to Tong Mengshi, in addition to makeup and rest, 90% of the time on the set is to wear blindfolds, which are almost completely invisible during night scenes, and need to rely on audible identification to complete the performance. During the day, you can follow the figure while filming blindfolded, but at night it is more troublesome and requires repeated shots. This extreme interpretation method and the difficulty of performing make Wuzhu’s role more engaging, but it also tests the actor’s acting skills.

  As a robot, Wuzhu itself is fundamentally different from humans in terms of emotion, cognition and behavior. When interpreting Wuzhu, Tong Mengshi is required to present the robot’s mechanical characteristics and artificial intelligence behavior patterns through precise body control, suppression of emotional expression and special processing of voice. In terms of body language, Tong Mengshi makes the audience feel the non-human characteristics of the character through repeated and meticulous practice. Every shot of Wuzhu is precise and decisive, like a sharp sword unsheathed, showing its sharp edge. In terms of language performance, Tong Mengshi’s feeling of language frustration in the corner of Wuzhu is also in place. The electronic voice and intonation of the character design enhance the character’s convincing power, allowing the audience to enter the play in one second.

  The segment that moved the audience was the mutual trust between Wuzhu and Fan Xian. On the wedding night, Wuzhu secretly sneaked into Fan’s mansion to give advice. Wuzhu, who was confused with memory, didn’t even dare to believe himself, but still chose to protect and trust Fan Xian. He was no longer the mechanical existence who would only follow orders and perform tasks, but a living individual with his own thoughts, emotions and choices. In terms of emotional expression, Tong Mengshi skillfully completed Wuzhu’s evolution from rationality to sensibility, not only maintaining the essential characteristics of the robot, but also showing its gradually awakening human face, adding human warmth to the cold and treacherous world of martial arts.

  Tong Mengshi’s portrayal of the character of Wuzhu in "Qingyu Nian 2" reflects a high degree of physical training and emotional regulation ability, and has a deep understanding and analysis of the role of Wuzhu, which is affectionately called "Xiao Zhuzhu" by the audience. Next, Tong Mengshi also has "National Color Youth", "Qianqiu Ling", "New God Condor Heroes", "Fox Demon Little Matchmaker King Power", "Young White Horse Drunk Spring Breeze" and "Real Warrior" to be broadcast, which is worth looking forward to.

Scientists in China and the United States have created the most accurate map of the structure of the Milky Way to date

 

 
For a long time, we knew very little about the Milky Way, and we didn’t even know the exact location of the sun in the Milky Way. However, astronomers have recently used some observational data to create a new "map of the Milky Way" that will refresh our understanding of the Milky Way and the formation of galaxies. And with this map, we also know that the sun is almost exactly on the central plane of the Milky Way’s disk.
Hundreds of years ago, explorers made detailed maps across oceans and uncharted continents. Over the past half-century, human space probes have photographed much of the solar system. But while we know our own astronomical backyard, we don’t know enough about our cosmic community, the Milky Way. The reason is obvious. Just as "we don’t know the true face of Mount Lu, we can’t leave the Milky Way and look back at the panorama of the Milky Way."
Maybe you could dream that we would launch a spacecraft, take it out of our galaxy, and then go back and take a panoramic picture of the galaxy, but a spacecraft would only be able to do this after a journey of millions of years, which is obviously impractical. We still have a lot of unanswered questions about the galaxy, such as how many spiral arms the galaxy has, whether a large structure closest to the sun can be counted as a single spiral arm, and where our solar system is in the galaxy.
Recently, however, scientists are working to map the Milky Way from the inside out, so that for the first time, accurate maps of the Milky Way’s structure can be made. This promising future is the result of the collaborative efforts of several advanced radio and optical large telescope projects, including our Bar and Spiral Structure Legacy Survey of the Milky Way (BeSSeL). We have obtained an unprecedented 5,000 hours of observation time for the Very Long Baseline Array.
The preliminary results of our project provide a new picture of the Milky Way. In addition to better understanding the overall image of the Milky Way, we are also beginning to clarify why galaxies like the Milky Way exhibit spiral structures and how our galactic home is integrated with the entire universe.
Cosmic Neighborhood
In the early nineteenth century, William Parsons, the third Earl of Rousseau, built a 72-inch telescope – a "gigantic" telescope by the standards of the time. He observed and drew the M51 nebula (which we now call the Whirlpool Galaxy) with a distinct swirling arm pattern. However, without knowing how far M51 is or the scale of the Milky Way, it is not clear whether the vortex galaxy is a small structure in our Milky Way or a galaxy similar to the Milky Way.
Debate about these issues continued until the early twentieth century. It was not until the American scientist Edwin Hubble used techniques developed by Henrietta Leavitt to measure our distances to some bright stars that we learned that spiral galaxies and other spiral nebulae are outside the Milky Way and similar to the Milky Way. This discovery overturned the idea that the Milky Way is the entire universe.
By measuring the movement of gas throughout the Milky Way disk, the pancake-shaped region that makes up the main body of the Milky Way, astronomers have discovered that we actually live in a spiral galaxy. The main common types of galaxies include spiral galaxies and elliptical galaxies. The Milky Way, seen from a distance, may resemble the nearby spiral galaxy NGC 1300 and the Pinwheel Galaxy (M101). At the center of NGC 1300 is a bright, elongated structure that astronomers call the bar structure of the galaxy. Two blue spiral arms extend from both ends of the bar structure and gradually extend outward around the central bar.
Most spiral galaxies have bar structures, which are generally thought to have formed as a result of the attractive force instability of the galaxy’s dense disk. The central bar structure then rotates, creating a stirring effect that in turn may promote the formation of spiral arms (other processes, such as attractive force instability caused by massive clumps in the disk or attractive force disturbances in nearby galaxies, may also contribute to the formation of spiral arms). Spiral arms are easier to see in the blue light band, because spiral arms are huge star-forming star-producing houses that are more prone to emitting blue light. The Pinwheel Galaxy M101 is another galaxy that may resemble the Milky Way. Although the Pinwheel Galaxy does not have the central bar of NGC 1300, it has more spiral arms.
Astronomers have long believed that the Milky Way may have the characteristics of two galaxies, NGC 1300 and M101: a distinct long bar structure like NGC 1300, and multiple spiral arms like M101. But beyond these basic conclusions, there is still much controversy. For example, infrared observations by the Spitzer space telescope more than a decade ago suggested that the Milky Way may have only two main spiral arms. And radio-band observations of atomic hydrogen and carbon monoxide suggest that the Milky Way has four spiral arms. In extragalactic galaxies, the gas is concentrated in the spiral arms. In addition to the spiral arm feature, astronomers are also debating how far the sun is from the center of the galaxy, and what the sun’s vertical height is relative to the galactic midplane, the plane of the center of the disk.
About 70 years ago, scientists calculated the distance from some bright blue stars nearby. If these stars were marked on a map of the Milky Way, they would be part of three adjacent spiral arms. We call these three spiral arms the centaur arm, the local arm, and the Perseus arm. Around the same time, beginning in the 1950s, radio astronomers observed atomic hydrogen gas, which emits a characteristic radio signal with a wavelength of 21 centimeters. As this atomic hydrogen gas moves relative to the earth, its characteristic radio frequency is shifted by the Doppler effect, allowing astronomers to use the frequency shift to measure the speed of the gas’s movement and then map its location in the Milky Way.
Using this measurement method, astronomers adopted a sun-centered coordinate system: similar to the longitude and latitude of a globe, the Milky Way longitude (l) is zero in the direction toward the galactic center and increases clockwise within the galactic "equatorial" plane (the Milky Way is seen from the northern celestial sphere); the galactic latitude (b) represents the angle perpendicular to the plane of the galactic disk. The 21-centimeter characteristic radio signal of the hydrogen atom gas shows a continuous structure in the galactic longitude-velocity diagram, which most likely traced the galactic spiral arm structure. Later plots of the galactic longitude-velocity of carbon monoxide molecular gases also exhibited similar characteristics. However, this indirect mapping method may be ambiguous and not accurate enough to clearly show the spiral arm structure of the Milky Way.
A New Horizon
One reason we know so little about the structure of the Milky Way is that there is a lot of dust in the Milky Way. Dust absorbs visible light so efficiently that it obscures our view in most line-of-sight directions, preventing us from seeing very far. Another reason is that the size of the Milky Way is staggering: light from stars on the other side of the Milky Way takes more than 50,000 years to reach Earth. Such a distance makes it difficult to even tell which stars are close to us and which are far away.
Now, new optical telescopes operating in space, as well as new radio telescopes around the world, could allow us to better answer all kinds of questions about the Milky Way. The Gaia mission, launched in 2013 to measure the precise distances of nearly a billion stars in the Milky Way, will no doubt revolutionize our understanding of the different populations of stars that formed our galaxy. But because Gaia observes in the visible light band, which is easily absorbed and scattered by interstellar dust particles, Gaia may be affected by interstellar dust when observing very distant spiral arms. On the contrary, because radio waves easily pass through dust, radio telescopes can probe the entire disk, allowing us to use observations from such telescopes to map the overall structure of the disk.
At present, the two main observational projects to map the structure of the Milky Way are using the very long baseline interferometry (VLBI) technique in radio astronomy. The VERA (VLBI Exploration of Radio Astrometry) project in Japan uses four radio telescopes, ranging from northern Japan (Mizusawa, Iwate Prefecture) to the southernmost Okinawa Islands of Ishigaki and the easternmost Ogasawara Islands, across Japan. The Very Long Baseline Array used by our BeSSeL sky survey program includes 10 telescopes, ranging from Hawaii to New England to St. Croix in the U.S. Virgin Islands, across most of the Western Hemisphere.
Because the distance between the telescopes that make up the Very Long Baseline Array is nearly the same as the diameter of the Earth, the array can achieve angular resolution that far exceeds that of any other telescope at any wavelength. The researchers must observe simultaneously with all the telescopes in the array, and use the world’s best atomic clocks to synchronize the data recorded by computers at each site. They then transport the recorded data to a dedicated computer, which processes the signals collected by each telescope. If our eyes are sensitive to radio waves, the calibrated image is an ultra-high definition digital image that we can see at radio wavelengths that is parsed by almost the entire width of the Earth.
Such images have incredible angular resolution (better than 0.001 arc seconds: if the entire celestial sphere is divided into 360 degrees, then 1 arc second is 1/3600 of a degree). By contrast, the human eye can only resolve structures for about 40 arc seconds at most, and even the Hubble Space Telescope can only achieve a resolution of about 0.04 arc seconds.
Using the VLBI, we can measure the position of a bright star in radio waves relative to a background quasar (which is actually a bright, active black hole at the center of a distant galaxy) with an accuracy of close to 0.00001 arcseconds. In this way, we can measure very far distances by measuring the triangular parallax effect. The triangular parallax effect is that when viewed from different positions, nearby celestial objects appear correspondingly in different positions in the background starry sky. You can extend your arms forward, raise your thumb, and simulate this effect by alternately closing your left and right eyes to observe the thumb. Because our eyes are a few centimeters apart, when we alternately observe the thumb at an arm’s length with our left and right eyes, the thumb will be offset by about 6 degrees relative to the distant background object. If we know the distance between the two observation positions, and the angular displacement observed, we can easily calculate our distance from the observation target. This is the same principle that surveyors use to map cities.
Ideally, astronomers who want to map the structure of spiral arms should observe young, massive stars. These short-lived stars are usually associated with violent star formation in spiral arms, and such stars are so hot that they can ionize the surrounding gas, causing it to emit blue light. Therefore, in theory, these stars can serve as beacons for observing the spiral arms of galaxies in the visible light range.
But because these stars are surrounded by the Milky Way’s dust disk, we cannot easily observe them throughout the Milky Way. Fortunately, water and methanol molecules outside the ionized regions of these hot stars can serve as very bright radio sources, because they emit large amounts of natural "masers" that are barely attenuated by galactic dust. The term maser is an acronym for "microwave amplification by stimulated emission of radiation," which means that a maser is actually a laser in the radio band. In an astrophysical setting, maser radiation comes from a solar system-scale gas cloud of mass comparable to that of Jupiter. Maser sources appear as very bright point sources in radio images. Therefore, the maser source is an ideal target for triangulation parallax measurement.
A new picture of the Milky Way
Using the BeSSeL and VERA projects, astronomers have used triangulation parallax to measure the distances of about 200 young, hot stars. The data spans the Milky Way, covering about a third of the galaxy and revealing four very long spiral arms.
The resulting "map of the Milky Way" also shows that the Sun is very close to the Milky Way’s fifth spiral arm, which appears to be an isolated spiral arm known as the "local arm". Previously, this section of the spiral arm was called the "Orion Arm Spine" or "Local Arm Spine", that is, this spiral arm resembles a small accessory structure extending from the main spiral arms of other galaxies. However, the interpretation of this "arm spur" may be wrong. In our BeSSeL data, this spiral arm is isolated, orbiting the Milky Way less than a quarter of a turn. Although the local arm is shorter in length, in this arm the star formation rate can be comparable to that of the Perseus Arm of the same length. Interestingly, astronomers once thought of the Perseus Arm as one of the Milky Way’s two main spiral arms (the other being the shield-centaur arm). However, we found that the star formation rate decreased significantly as the Perseus Arm moved away from the Sun and towards the Milky Way. This suggests that the Perseus Arm does not appear to be a very obvious spiral arm to outside observers.
By mapping the three-dimensional positions of a large number of young stars and measuring and modeling their velocities, we can calculate the basic parameters of the Milky Way. We found that the distance from the sun to the center of the Milky Way is 8150 ± 150 parsecs (or 26,600 light-years). This is smaller than the 8500 parsecs recommended by the International Astronomical Union a few decades ago. In addition, we found that the Milky Way rotates at 236 km/s at the position of the sun, which is about 8 times the speed of the earth’s rotation around the sun. Based on these parameter values, we found that it takes about 212 million years for the sun to rotate around the Milky Way. This also means that the last time our solar system was where the Milky Way is now, dinosaurs were still roaming the earth.
The Milky Way’s inner disk, which lies within the sun’s position, is so thin that it is almost a flat plane. But the sun’s vertical height relative to this plane has been controversial. Recently, some astronomers have measured that the sun is 25 parsecs (82 light-years) above the inner disk, but our measurements differ significantly from this estimate. By fitting the plane in which massive stars with precise distances and positions are located, we can determine that the sun is only about 6 parsecs (20 light-years) above the plane. This height is only 0.07% of the distance from the sun to the center of the galaxy, which means that the sun is very close to the mid-plane of the galaxy. We also confirmed the previously observed galactic warping, in which the outer disk of the Milky Way gradually deviates from the inner disk and begins to curve upward on the north side and downward on the south side, somewhat like a curved potato chip.
In order to describe observations, astronomers usually divide the Milky Way into four solar-centered quadrants. Using this coordinate, we found spiral arms in the first three quadrants. To map the fourth quadrant, we need observation equipment located in the southern hemisphere. We are conducting a southern hemisphere observation project and plan to use telescopes in Australia and New Zealand to make observations.
While we await these observations, we can use observations from atomic hydrogen and carbon monoxide to extrapolate the known spiral arms to the fourth quadrant. The structures revealed by these observations are consistent with previous theoretical conjectures of the Norma-Outer, Shield-Centaur, Sagittarius-Carina, and Perseus arms. It should be noted, however, that we have only made one observation of the star-forming region far from the center of the Milky Way. The distance of this region we observed, combined with its position in the galactic meridian-velocity map of carbon monoxide, gives us some confidence in how to "map" the spiral arms at the other end of the galaxy.
However, we need more observations to validate our model. We now have a clearer picture of our galactic home. We may live in a four-arm spiral galaxy with a bright and symmetrical central bar. Our sun is almost entirely in the mid-plane of the Milky Way disk, but the sun is far from the center of the galaxy, about two-thirds of the galactic radius. In addition to the spiral arms that can circle the galaxy almost once, the galaxy has at least one additional spiral arm segment (the local arm), and each major spiral arm may have many forks. These spiral arm features make our galaxy appear fairly normal, but certainly not typical. About two-thirds of spiral galaxies have a central bar structure, so the Milky Way belongs to the bar spiral galaxy that makes up the vast majority of spiral galaxies. However, the Milky Way has four clear, well-defined, and fairly symmetrical arms, which makes the Milky Way unique because most spiral galaxies have far fewer arms and are relatively messy.
More mysteries
Although we have some new answers, there are still many important unanswered questions. Astronomers are still debating how the spiral arms arose. There are two competing theories on the issue. One theory holds that attractive force instability at the galactic scale creates a persistent spiral arm pattern of density waves. Another theory holds that some spiral arm fragments will be stretched over time due to instability at small scales, magnified, and then connected to form longer spiral arms. In the former theory, the spiral arms can last for billions of years, while in the latter theory, although the life of the spiral arms is short, the new spiral arms will appear multiple times throughout the evolutionary history of the galaxy.
Since the Milky Way does not have a clear date of birth, it is difficult to determine its exact age. The current popular view is that as many smaller protogalaxies that formed first in the history of the universe collided and merged, they gradually merged to form what is now the Milky Way.
The Milky Way was already a large galaxy about 5 billion years ago, but at that time it may have looked very different than it does now, because the merging process is likely to break up any existing spiral structure.
We need more observations to improve our existing picture of the structure of the Milky Way, and the next generation of VLBI-enabled radio telescope arrays will facilitate this. Such arrays in the pipeline include the Square Kilometer Array in Africa and the Next Generation Very Large Array in North America. Both are giant radio telescope arrays spanning an entire continent, and they are expected to be fully operational by the late 2020s. They will have a much larger signal-gathering area than existing arrays, and will therefore be able to detect faint radio emissions from stars, allowing us to see farther in the Milky Way. Ultimately, we hope to clearly map the building structure of the Milky Way Home to confirm or disprove the theory of the formation of the Milky Way’s magnificent spiral arm structure.

Rebs becomes cat Booth, Pikachu becomes dog Kachu: Nvidia’s latest AI open source, all things change faces with only one picture | Demo

  Qubit, report | official account QbitAI

  Nvidia’s new AI can quickly turn a golden retriever in a video into a meerkat.

  Just show the AI two static pictures of meerkats:

  Before seeing these two images, the AI had never seen an animal like a meerkat, not in the training dataset.

  There were many other animals that the AI had never seen before. Just give it a photo or two to familiarize it with, and you can replace the golden hair with their faces.

  For example, ferocious big cats:

  In this way, the Golden Retriever’s relatives, such as huskies, are even more concerned:

  Although the same translation is from picture to picture, and the same is unsupervised, this AI is very different from the predecessors of the horse-turned-zebra. The predecessors can only translate between animals they have seen. During training, I have seen many horses and many zebras;

  And NVIDIA’s new contestant is equivalent to never seeing a zebra in training. Animals that are not in the training dataset, as long as they can see one or two pictures during the test, it is enough.

  The Few-Shot Learning algorithm greatly reduces the requirements for training data.

  The team has open-sourced the algorithm and launched a one-click face-changing demo. So, let’s play with it today and then talk about the principle.

  The wrong and correct way to open

  I tried the demo on the chicken freezer.

  The first question is to pass a cold meow up and select the head with the box.

  ?? Thank you to my old Si Xia

  Therefore, all kinds of animals have gained a cold side.

  The second question, passed a Rebs up, which was also half-sided:

  Unexpectedly, the orcs who generated the aura of nobility:

  AI’s artistic talent is upon us, but I still want to solemnly remind you:

  The demo application is called PetSwap. Please select the correct opening method. Here is the correct demonstration.

  The third question is to break through the dimensional wall. Go, Detective Pikachu:

  Everyone donned Sherlock Holmes hats, but only the hound in the upper right corner unlocked the sexy blush.

  What an elegant and fulfilling morning.

  Play enough, it’s time to see the principle.

  Never seen animals, just take a look

  As mentioned at the beginning, this is a small sample translator. It needs to replace a Content Image, such as a golden retriever, with a Class Image, such as a husky or a cougar.

  The model is divided into three parts:

  One is the Content Encoder, the pink part. It maps the input content map (Golden Retriever) to a Content Latent Code.

  The second is the class encoder (Class Encoder), the green part. First map each class map (Husky) to a code. Then take an average to get the entire class code.

  The third is the decoder (Decoder), the blue part. First map the category lattice code to the adaIN parameter, and then decode the content lattice code to generate the translation result map.

  When training, there are golden retrievers and huskies in the dataset. The AI is between these categories and cultivates the face-changing skill:

  However, there are no cougars in the training dataset. What should I do to generate cougars during testing?

  Here’s the secret: When the class diagram and the content diagram look the same, let the model generate a reconstruction.

  In this way, as long as you temporarily look at a cougar (or a few) during the test, you can turn the unseen moment into a seen one. It is not difficult for the AI to translate the dog in the training dataset into a cougar:

  You’re done.

  Go play, too!

  Such a (excellent) show of AI, you must also want to train it.

Make good use of digital technology and build a "big ideological and political course"

Make good use of digital technology and build a "big ideological and political course"

Peng Qinghong

  abstract The integration of digital technology and "big ideological and political courses" has given new vitality to the reform and innovation of ideological and political education in the new era. To make good use of digital technology and build a "big ideological and political course", first of all, we must fully understand the fit between digital technology and "big ideological and political courses". Secondly, we must identify the focus of the combination of digital technology and "big ideological and political courses" from the perspectives of subject connection, resource sharing, teacher-student interaction, scene reconstruction, and model innovation. Finally, we must deal with the primary and secondary relationships, red college relationships, external and internal relationships, public-private relationships, and new and old relationships that combine digital technology and "big ideological and political courses" to promote the development of high-quality connotations in the construction of ideological and political courses.

  keyword Great Ideological and Political Course; Digital Technology; Digitization

  Since the 18th National Congress of the Communist Party of China, especially since the Supreme Leader General Secretary personally chaired the school’s ideological and political theory teacher symposium, the status of ideological and political courses in the overall strategic situation of the Party Central Committee’s governance of the country has become increasingly prominent, and the construction of ideological and political courses has also made significant progress. The construction of "big ideological and political courses" is an important breakthrough point to promote the high-quality development of ideological and political courses during the "14th Five-Year Plan" period, and has also become a highlight of the reform and innovation of ideological and political courses in recent years. The General Secretary of the Supreme Leader has successively emphasized that "we must use new media and new technologies to make work come alive, and promote the high degree of integration of traditional advantages of ideological and political work with information technology." "The digitalization of education is an important breakthrough for our country to open up a new track for educational development and shape new advantages in educational development." Therefore, to promote the construction of "big ideological and political courses", we must also make good use of digital technology, so that digital technology and "big ideological and political courses" can be fully integrated and mutually promoted, and constantly cultivate new potential, open up new tracks, and shape new patterns for school ideological and political education in the new era.

  Comprehensive understanding of the fit between digital technology and "big ideological and political courses"

  To make good use of digital technology and build a "big ideological and political class", we must first fully understand the inherent fit between digital technology and "big ideological and political class". On the one hand, digital technology can promote the quality and efficiency of "big ideological and political class"; on the other hand, the needs and problems in the construction of "big ideological and political class" can also promote the continuous innovation and optimization of digital technology. The integration and mutual assistance between the two make the digital expansion of ideological and political class possible and produce good results.

  1. Digital technology can promote the effective construction of "big ideological and political courses"

  The development of digital technology has brought new opportunities and development space for the construction of "big ideological and political courses". In recent years, the construction of "big ideological and political courses" has achieved obvious results under the high attention of the party and the state, but it still faces some problems. The "big lessons of life" and big vision of the "big ideological and political courses" contained in the "big ideological and political courses" require "us" including all ideological and political teachers, all educators, and the whole party and society to make good use of them. At present, scholars have not fully agreed on the concept of "big ideological and political courses", but the industry has linked the construction of "big ideological and political courses" with big goals, big classrooms, big ideological and political courses, big patterns, big platforms, master resources, and big coordination. At the practical level, "big ideological and political courses" not only means that ideological and political courses should be expanded in depth, but also means that the breadth of ideological and political courses should be expanded – open the door to do ideological and political courses. In the construction of "big ideological and political courses", it is necessary to realize the upgrading and transformation of classroom teaching content, methods and management aspects, to mobilize the joint participation of various social resources, to open up theoretical classrooms, practical classrooms, online classrooms, etc., to realize the integrated construction of ideological and political courses in large, middle and primary schools, and so on. The realization of these tasks, especially the cracking of some difficult problems, requires the joint efforts of front-line ideological and political educators, the strong organizational guarantee of ideological and political course construction management institutions at all levels, and also requires strong digital technology support and services.

  The construction of "big ideological and political courses" requires the intervention and support of digital technology. Looking at the world, the digital transformation of education has become a consensus, and the digital construction of "big ideological and political courses" is imperative. On the one hand, the application of 5G, big data, Internet of Things, artificial intelligence and other technologies has made the educational environment of ideological and political courses continue to change in the direction of networking, digitalization and intelligence, and the experience of teaching practice has also changed from a static plane at the visual level to a dynamic interactive one at the audio-visual level. Driven by the digital wave, promoting the modernization of education is the general trend, the need for development, and the direction of reform, which can better meet the precise and efficient reform requirements put forward by the development of the times for ideological and political courses. On the other hand, the post-00s generation of students grew up with digital technology, not only has a demand for memorized learning of theoretical knowledge, but also hopes to immerse themselves in the educational effect of ideological and political courses to enlighten the mind and cultivate emotions. The teaching mode of ideological and political courses, which has been spawned by digital technology, provides a platform and breakthrough point for the innovation of the teaching content and methods of "big ideological and political courses", and meets the expectations of educational objects.

  2. The "big ideological and political class" can promote the development of digital technology

  Make good use of digital technology and build a "big ideological and political course". Digital technology is applied to the specific educational field as a means to achieve the purpose of changing the educational model and improving the educational effect. In this process, the number of schools involved in the construction of the "big ideological and political course", the large number of students, and the wide range involved have also continuously promoted the innovative application and development of digital technology.

  The construction of "big ideological and political courses" can accelerate the innovation and development of digital technology. On the one hand, the construction of "big ideological and political courses" has stimulated the innovation power of digital technology. In the digital age, the speed of technological update and iteration is dazzling. The deep integration of digital technology and ideological and political courses requires digital technology to continuously carry out self-innovation and iterative upgrading. It is necessary to summarize the development and utilization of historical resources, cultural resources and policy resources by existing VR (virtual reality) and AI (artificial intelligence) technologies in the construction of "big ideological and political courses", and create a teaching model with diverse styles and stable structures; it is also necessary to constantly explore the application of artificial intelligence, big data, virtual reality and other emerging technologies in the field of "big ideological and political courses" construction, and continue to tap the potential of technology to change education development. On the other hand, the construction of the "Great Ideological and Political Course" is conducive to the construction of the digital technology system. "Digitalization" is an overall system supported by a variety of technologies, which needs to be applied to a variety of technologies such as big data, cloud computing, Internet of Things, blockchain, artificial intelligence, etc. A single unit or team cannot support its overall operation. Therefore, riding the east wind of the construction of the "Great Ideological and Political Course", a composite system project involving multiple subjects and multiple forces has been built, and the support system of digital technology has also involved schools, society, enterprises, governments and other forces. " The multi-department, multi-field, and multi-level cooperation in the education work pattern provides support for the integrated development of digital technology, which is conducive to the joint construction of cross-field digital technology.

  Identify the focus of combining digital technology with the construction of "big ideological and political courses"

  The combination of digital technology and "big ideological and political courses" is not a simple "1 plus 1 equals 2", but a mutual integration and internal unity between them. In practice, we must identify the focus of the combination of digital technology and "big ideological and political courses", promote the high degree of integration of traditional advantages of ideological and political work with information technology, enhance the sense of the times and attractiveness, and create a new pattern of digital development of "big ideological and political courses".

  1. Use digital technology implementation of the main body connection of the "big ideological and political course"

  The "big" of the "big ideological and political course" requires fully mobilizing the rich resources and strength contained in the social big classroom, building a "big classroom", building a "big platform", and building a "master resource". This requires the strength of the whole society, collective efforts, and joint creation and construction. In the construction of the "big ideological and political course", the multiple subjects involved in education and teaching should form a good organizational relationship of collaborative participation and common construction, so as to truly realize the effective combination of the ideological and political "small classroom" and the social "big classroom".

  Different from the traditional single teaching method, digital technology can enrich the ways and means for multiple subjects to participate in the construction of "big ideological and political courses" online and offline through system sharing, resource co-construction, information exchange, network connection, etc., break the time and space restrictions and information barriers, and promote cross-regional, cross-departmental, and cross-school information flow and linkage and collaboration. The use of digital technology implementation of "big ideological and political courses" is connected to the main body, which not only reduces work costs, but also greatly improves work efficiency. For example, in recent years, many schools have cooperated with the forces of the Marxist Institute, the Propaganda Department, the Ministry of Students and Workers, the Youth League Committee and other functional areas of business, contacted brother colleges and universities, the "big ideological and political class" practice teaching base, various venues and other institutions to cooperate, and established the virtual teaching and research room of ideological and political classes, digital teaching platform, etc., to help the teachers of ideological and political classes in various schools to communicate and share resources in real time, and give full play to the different resource advantages of society, government, family, enterprise, community, etc., so that ideological and political classes can effectively enhance the teaching effect of theoretical teaching and practical education, knowledge infusion and situational experience in the connection between inside and outside the school, online and offline.

  2. Build a digital platform to promote the sharing of resources in "big ideological and political courses"

  Open sharing of digital educational resources is a key move to narrow the digital divide and education gap. With its scalable, distributed, and advanced technologies such as multimedia large file storage, management, and resource retrieval and call, digital technology automatically stores and intelligently sorts large amounts of data, eventually forming a large-capacity, accurate, and callable virtual data resource library. Building a digital platform to promote the resource sharing of "big ideological and political courses" can collect and integrate rich social resources and life materials, and realize the co-construction and sharing of resources in classroom teaching to improve the allocation and use efficiency of "big ideological and political courses" teaching resources.

  The establishment of a digital teaching platform is conducive to the sharing of resources for "big ideological and political courses". First, share teaching resources. Relying on the digital teaching platform, integrate policy information, research results, case materials, practice test questions and other resources of various schools at all levels, realize the collection and construction of digital resources, and form a teaching resource library that integrates high-quality teaching materials such as courseware, handout drawings, course analysis, and auxiliary documents for ideological and political courses. Secondly, expand the dissemination of resources. Encourage teachers and students to create digital teaching resources such as micro-movies, animations, music, and short videos around the teaching content of ideological and political courses. Collaborative lesson preparation and experience sharing are carried out through online MOOCs, live courses, special seminars, and heterogeneous courses. Continuously promote the dissemination and update of teaching resources and information exchange. Finally, optimize the supply of resources. Facing diverse needs, the data resources of the digital teaching platform can be quickly retrieved, freely combined and flexibly called modules and functions for teachers of ideological and political courses according to user requests, so as to realize personalized supply and service of resources, and effectively improve the efficiency and business level of teachers in lesson preparation. For example, the construction of the National Smart Education Public Service Platform, the National Ideological and Political Theory Teacher Network Collective Lesson Preparation Platform, and the Digital Horse Academy have all built a better online platform that spans time and space for ideological and political course teaching, aggregating higher-quality, more systematic, and more types of digital educational resources, and promoting the sharing and co-construction of high-quality resources.

  3. Use digital tools to promote teacher-student interaction in "big ideological and political classes"

  In the construction of "big ideological and political courses", while innovating the big social classrooms, the role of the main channel of ideological and political "small classrooms" must be guaranteed. At present, the lack of interaction is an important reason that affects the effectiveness of ideological and political courses, and solving this problem is also the focus of ideological and political course reform and innovation. As a means and method, digital technology can provide new interactive methods and emotional experiences for ideological and political course teaching, effectively enhancing the vividness and effectiveness of teaching.

  With the help of digital tools, promote the interaction between teachers and students in the "big ideological and political class". First, with the help of digital tools to enhance the pertinence of teaching. Ideological and political class teachers use digital technology to effectively grasp students’ learning habits, thinking characteristics, psychological dynamics, etc., analyze the information fed back from the teaching process and result data, and grasp the learning situation in a timely manner. Scientifically arrange lesson preparation, adjust teaching progress and class management will also effectively help students review teaching knowledge online, record experiences in class, exchange views and ideas, and complete practice assignments. Second, with the help of digital tools to create a good atmosphere in the classroom. In teaching practice, more and more ideological and political class teachers pay attention to promoting student interaction through the creation of red micro-movies, ideological and political talk shows, virtual reality experiences, drama role-playing and other diverse forms. Through the presentation of digital means, from static pictures to dynamic pictures, from silent words to sound voice, stimulate students’ interest, so that they can actively explore classic theoretical ideas, red history and culture, and contemporary development reality. The third is to manage classroom order with the help of digital tools. Ideological and political class teachers use digital means to name, ask questions, answer questions, and evaluate in a timely manner in classroom teaching. Homework arrangement, homework correction, and interactive Q & A before and after class are all good ways to further consolidate and expand the effect of teacher-student interaction.

  4. Use digital virtual innovation to recreate the scene of "big ideological and political class"

  The teaching of ideological and political classes requires relying on and creating situations to better achieve the effect of enlightening the mind and moisturizing the mind. "Great Ideological and Political Classes" expands the space of ideological and political classrooms from schools to the space of various fields of society. Through technical means such as smart classrooms, 5G, virtual simulation, and holographic teaching in digital technology, social development scenes, historical and cultural scenes, and family life scenes can be introduced into ideological and political classrooms. Teachers can call all kinds of video information and network data at any time, and use animation, video, VR glasses, and other products to create real-time shared and immersive classroom scenes. On the one hand, digital technology is used for virtual presentation of real scenes. Digital technology breaks the constraints of spatial boundaries on the teaching scene of ideological and political courses. Using digital twin and other technologies, in the form of live broadcast, scene simulation, VR panoramic images, etc., the materials and scenes of revolutionary old sites, historical memorial pavilions, and museums can be virtually presented, so that students can be immersed in the classroom and realize "cloud visit", "cloud classroom" and "cloud interaction". Ideological and political course teachers can also interact synchronously with heroic models, advanced role models, venue commentators, etc., and extend the classroom to educational bases such as fields, factory workshops, scientific research institutes, and old revolutionary base areas, further expand the new field of education and teaching, save the cost of ideological and political classroom teaching transition, and improve the educational effectiveness of "big ideological and political courses". On the other hand, digital technology is used to recreate virtual scenes. Some historical events, revolutionary ruins, historical figures, etc. cannot be presented through VR panoramic shooting, but digital restoration, 3D modeling, virtual people, etc. of digital technology can also be used to restore and reproduce these virtual teaching scenes, making the "big ideological and political class" more vivid.

  5. Deepen digital transformation and realize the model innovation of "big ideological and political courses"

  As a leading force in the world’s scientific and technological revolution and industrial transformation, digital technology has brought about changes in "big ideological and political courses", not minor repairs, but profound changes in the education and teaching methods of ideological and political courses. It is a systematic model innovation. From resource supply, information sharing to interactive models, teaching methods, to evaluation systems, feedback mechanisms, etc., the combination of digital technology and "big ideological and political courses" will bring about a deeper transformation and development of ideological and political education in the new era.

  In terms of resource construction, the "Great Ideological and Political Course" digitizes the ideological and political elements and social resources, matches the teaching content and methods according to the actual needs of students, and takes into account all aspects of resources to form a top-down, collaborative and cooperative platform, which subverts the previous traditional teaching resources supply and dissemination methods. In the interactive mode, teachers of ideological and political courses make full use of MOOCs, live broadcasts, short videos, etc., to make the theoretical ideas in the course "live", character events "move", and historical and cultural "light up", and continuously enhance the affinity and appeal of ideological and political courses, which helps to break people’s stereotypes of ideological and political classroom teaching in the past. In the evaluation feedback, the use of digital technology to empower the whole section, the whole process, with the help of teachers and students digital portraits and visualization technology, monitoring the process and results of education and teaching, prompting the evaluation method from the score-oriented small data evaluation to the whole-process literacy assessment of the big data evaluation, from the test-type result evaluation to the real-time performance-type process evaluation, to achieve the ideological and political course teaching evaluation system and feedback mechanism optimization innovation.

  Handle the relationship between digital technology and the construction of "big ideological and political courses"

  Technology is a "double-edged sword", and whether it can play a positive role depends on how it is used. In the construction of "big ideological and political courses", the appropriate use of digital technology to empower the teaching of ideological and political courses can effectively enhance the sense of the times and attractiveness of ideological and political courses; on the contrary, it will deviate from the original intention and goal of ideological and political course reform and innovation. To grasp the development direction of "big ideological and political courses", we must properly handle the multiple relationships between digital technology and the construction of "big ideological and political courses".

  1. Primary and secondary relationship: The digital construction of "big ideological and political courses" should adhere to the leading position of the classroom

  In the digital construction of the "Great Ideological and Political Course", the status and attributes of the ideological and political classroom have not changed. In other words, in the relationship between primary and secondary, classroom teaching is still in a dominant position, and digital technology is an auxiliary means. Digital technology is a tool to promote the digital transformation of ideological and political courses and improve the quality of ideological and political education. The value of technology in the reform of ideological and political courses lies in the transformation, expansion, and enrichment of educational content and methods, and is a means to serve the improvement of classroom teaching quality. No matter what the form of technological innovation is, all technological means must fall on the improvement of teaching quality, and digital technology cannot be blindly superimposed on the classroom in order to follow the trend and compare. Adhering to the content of classroom teaching as king, and constantly improving the quality of ideological and political courses to build morality and build people, is the purpose of the construction of the "Great Ideological and Political Therefore, the participation of digital technology in the construction of "big ideological and political courses" should also be subject to the fundamental task of Lide and cultivating people, and cannot become a "dazzling skill" or "whole job" at the pure technical level. No matter where the space-time field of ideological and political courses is broadened, we must always adhere to the central position of the main channel of the classroom in the construction of digital ideological and political courses, respect the main position of teachers and students in classroom teaching, and consolidate the main channel of classroom teaching to ensure the coordination of the overall classroom content.

  2. Red College Relationship: Digital "Great Ideological and Political Course" Must Adhere to the Value Leadership of Mainstream Ideology

  The construction of "big ideological and political courses" uses digital technology to condense more educational resources, but diverse teaching resources do not mean diversified value orientation. As a direction of ideological and political course reform and innovation, "big ideological and political courses" have the attributes of ideological and political courses to be firmly maintained, we must grasp the red college relationship in the construction of "big ideological and political courses". The "red" here refers to the clear political and ideological attributes of ideological and political courses. As a key course to implement the fundamental task of building people with morality, it is necessary to strengthen the orientation of socialist ideology to the construction of "big ideological and political courses". The "special" here refers to the professional level of digital technology itself, that is, sufficient professional standards can empower the ideological and political class to increase efficiency, otherwise it will be counterproductive. The digital transformation of the "big ideological and political class" should adhere to the principle of political orientation, and appropriately infiltrate the mainstream ideology into the design and application, evaluation and reflection of digital technology, strengthen the mainstream ideology through technology, and at the same time use technology to block the interference of wrong ideas and vulgar information on the classroom, and guide students to form ideological values that meet the requirements of the mainstream socialist ideology.

  3. Relationship between the outside and the inside: Digital technology should deeply empower the education and teaching innovation of "big ideological and political courses"

  The integration of digital technology and "big ideological and political courses", technology is only an appearance, its essence is still a classroom revolution, emphasizing the realization of the teaching effect of ideological and political courses and the effectiveness of classroom teaching. The use of digital technology in "big ideological and political courses" is not for formal teaching performance, but to let technology truly empower the revolution of the teaching mode of ideological and political courses. The most fundamental thing is to reshape the classroom, so that "big ideological and political courses" can take into account the depth of theory, the thickness of history, and the validity of policies. The application of digital technology deeply empowers the education and teaching innovation of ideological and political courses. It is necessary to make full use of learning analysis systems, adaptive systems, AI teaching assistants and other auxiliary teaching technologies to promote the transformation of teaching and learning models in classroom teaching, and promote the transformation of teaching models from the traditional "teacher-student" binary structure to the "teacher-machine-student" multi-structure; also through the collection and sorting of learning and public opinion, accurately analyze the knowledge points that students are interested in and are still confused, scientifically and rationally create teaching scenes, allocate educational resources, and change teaching methods. Realize the "big ideological and political class" model in which teachers "teach" in a targeted manner and students "learn" proactively.

  4. Public-private relations: The digital transformation of the "big ideological and political class" should balance private space and public sphere

  With the rapid development of digital technology, a large amount of data is stored and widely disseminated in the cloud in the form of pictures, videos, animations and other information, and a series of digital ethical issues have arisen. For example, the digital field of ideological and political courses has not only the collection of a lot of private information, but also a transparent public field that needs to be shared. With the embedding of digital technology into classroom teaching scenes, it is more convenient to collect and quantify the identity information and behavioral characteristics of educational subjects. The acquisition and collection of private information and personal data of educational subjects by third-party institutions is easy to infringe the privacy of teachers and students’ private information, personal opinions and other privacy risks, resulting in the privacy and security risks of teachers and students in the digital transformation of "big ideological and political courses". At the same time, those public spaces that need to be shared in the digital world also have issues of fairness in the use of digital technology and information openness. Therefore, in the digital construction of "big ideological and political classes", on the one hand, it is necessary to standardize the management system of technology use in classroom teaching, and integrate ethics into the practice framework of classroom teaching with the operating principles of transparency, credibility, controllability, and security. On the other hand, it is also necessary for ideological and political class teachers to strengthen digital social responsibility in operation, improve their digital literacy, clarify the awareness of rights and responsibilities in the information age, prevent bad and even illegal behaviors such as spying on privacy and leaking information, do a good job in privacy management up and down the classroom, and consciously maintain the ethical order of digital space.

  5. New-old relationship: promote the digital construction of "big ideological and political courses" according to the time, people and circumstances

  In the face of the ever-changing digital wave, the digital reform of "big ideological and political classes" needs to consider and deal with the tolerance limits of teachers of different age groups for new technologies and the appropriate transformation of old and new classrooms in technology. For teachers, to master digital technology, ideological and political class teachers need to mine the educational elements contained in it and integrate it into classroom teaching. However, the speed of digital technology update, the amount of resources provided, and the variety of operation methods can easily cause teachers to be overloaded with technology. Especially for older ideological and political class teachers, some of them are difficult to integrate into the digital world in a short time, so the use of digital technology becomes a burden and shackle for their teaching, and the classroom effect will be counterproductive. For colleges and universities, some schools do not seek teachers’ opinions, do not understand students’ needs, and promote MOOCs, online classes, and virtual simulation ideological and political classes regardless of the actual situation when the preparation of teachers, funds, and technologies is not yet mature. Finally, there may be problems such as teaching content that does not meet students’ needs, or the image quality of the digital link is rough, the operation is inconvenient, and the system responds sluggishly, or the classroom teaching shows the "self-talk" of teachers and technology, which affects the original effect of classroom teaching, reduces the experience of teachers and students, and then arouses the emotional resistance of teachers and students to the digital transformation of "big ideological and political classes". Therefore, to promote the digital construction of "big ideological and political courses", we must combine the teachers’ affordability and actual level, and according to the school’s own development orientation and actual situation, deepen and gradually innovate at every level.
