Tech Hammer

"Is it really that difficult to build a holographic stage in the Beehive Stadium?" Tian Yanzhen asked as soon as Director Chen left.

"It's still possible in one year, but it's only possible. In four months, it's absolutely impossible! It's too big. There is no laboratory data to support whether the existing materials can support such a large site. The light test may require two , three months. If it doesn’t work, you may have to study new material ratios or redesign a new frame structure. This year may not be enough. And it also involves the transformation of the entire Honeycomb Stadium lighting system..."

Ning Wei nodded and explained simply.

You don’t need too many words, these things can be understood by a scientific person.

"Oh, then think of another way. Everyone can carry the sedan chair. It's a good thing to have friends from all walks of life. If anything happens in the future, there will be more people to help you speak out." Tian Yanzhen said casually, and then used inquiry He looked at Ning Wei.

"Ahem, Director Tian, ​​if there's nothing else to do, I'll leave first. Now I'm going to help Director Chen find a solution."

"Okay, go ahead! Don't mess up this big project."

"Don't worry, Director Tian, ​​at least so far, I still have a 0-defeat record."

Well, when you should be confident, you still have to be appropriately arrogant and don't lose your reputation.

…

"Director Tian asked me to meet Chen Wenwen..." Ning Wei said to Liu Wei beside him on the way back to his office.

"I know, I saw him when he left." Liu Wei replied.

Ning Wei asked curiously: "Do you still know Director Chen?"

Liu Wei glanced at Ning Wei and said helplessly: "Strange? I have always paid attention to the Olympics. The most solemn event in the world, probably only those weirdos who are full of formulas will not care at all, right?"

Ning Wei nodded and responded: "If you are talking about strange words, it means handsome, knowledgeable, promising, broad-minded, successful in career, courageous, extraordinary conversation, talented, outstanding, etc. If that’s what it means, it’s probably right.”

Liu Wei thought for a while and found that although the other party was shameless, he could not refute, so he asked: "Director Chen came to you to use yesterday's three-dimensional display technology at the opening ceremony?"

Ning Wei nodded and said helplessly: "Yeah, but it's not realistic. The stadium is too big."

Liu Wei said: "Change the idea, how about splicing several stages together?"

Ning Wei shook his head and said: "It's not worth it. The lighting system needs to be modified, and a major project needs to be carried out on the stadium. It needs to be dismantled and restored to its original appearance, and then there will be games inside. In short, even if the technical difficulties are overcome, It is also a very wasteful approach. The application scene of the specially made large light source is too narrow and too wasteful. At least before the technology is updated, I will reject this plan."

This involves professional knowledge. Liu Wei couldn't get in the way, so he asked, "So you refused?"

"Why……"

Ning Wei sighed deeply and said: "That's the problem. I wanted to refuse, but Director Tian felt that I was very capable and could definitely think of ways and find innovations, so he still asked me to help. Director Chen came up with an idea to promote the achievements of China's scientific and technological progress over the years. Director Tian made sense, but I couldn't think of an excuse to reject it! So I still have to worry about it. The ancients said it well, the greater the ability, the greater the responsibility. The bigger.”

"Oh! What do you think?" Liu Wei responded. There was nothing wrong with Ning Wei's boasting.

If you want to make something different for the opening ceremony of this Olympic Games, Ning Wei is indeed a good choice. Time is too tight, and it is difficult for ordinary ideas to support such a big scene that attracts global attention.

"I don't have any ideas yet, and my brain is like a mush. What Director Chen means is that he came to me to show the great development of China's science and technology field in recent years, and to do something different from before. It's a pity, that boy Chen Diancheng He has told me many times that he wants to work in the direction of humanoid robots in the future. If he waits for results, the entire opening ceremony will be completed by robots, which will definitely be a good highlight. Now I can only start in other directions."

After saying that, Ning Wei asked casually: "I think the greatest scientific achievements in these years are our artificial intelligence platform, Ningxin and three-dimensional display. What else do you think?"

Liu Wei thought for a while and replied: "Don't just think about your one-third of an acre of land! Doesn't the perfect operation of our Huaxia Palace Space Station count as technological progress?"

Ning Wei couldn't refute these words and nodded: "Indeed, but you can't just drive the Tiangong directly to the hive to entertain the whole world, right? By the way, Experimental Cabin No. 2 also uses the system that my students participated in and connected It has joined our March smart platform, so you still can’t say that I only focus on my three-thirds of an acre of land.”

Liu Wei smiled: "Okay! I also know that the space station can't drive to the Bird's Nest, let alone other military technologies. But according to me, there is nothing we can do in such a short time. If I were As for Director Chen, he should just concentrate his resources on creating a grand scene at the opening, which will shock everyone first. Even if the quality of the rest of the performance is slightly worse, no one will care about it."

Ning Wei thought for a while, then nodded and said: "It's a plan, but our award ceremony yesterday was also very successful. We can also consider that it was mediocre before and there were a lot of scoldings, and then there will be a big turnaround in the end. As long as there is one Once everything is done, the opening ceremony should be considered a success. And this is actually the best choice. It will not cause any conflict with the already prepared plan, and it will be sufficient in time."

After listening to this suggestion, Liu Wei smiled even more happily and asked: "You just said that the holographic display cannot be used, so what did you use to flip it at the last moment? A huge Ning Xin model fell from the sky?"

Ning Wei frowned and thought, and asked: "By the way, generally speaking, what is the most important step before the opening ceremony ends? Is it over after the athletes enter the stadium?"

Liu Wei glanced at Ning Wei in surprise: "You really haven't paid much attention to the opening ceremony of the Olympic Games. Generally speaking, after the athletes enter the stadium, the next step is the Olympic torch relay, and finally the Olympic flame is lit. If conditions permit, you will still do it. Set off fireworks, and the opening ceremony will end after the fireworks."

"Oh, space station, light the sacred fire, space station, light the sacred fire..."

Repeating it over and over again, Ning Wei suddenly stopped and said, "Hey, Brother Liu, you said that Director Chen's request is to experience the sense of technology and have a big scene. Let's light the space station and the torch. How about combining these two pieces? Doesn’t it look taller immediately?”

This proposal - Liu Wei was completely stunned. Tong Ning, who really didn't want to think about how he connected these two unrelated things, frowned and asked: "What are you - mean?"

Ning Wei said slightly excitedly: "What do you think about using the space station to light the torch? Think about it, the torchbearer running on the field suddenly threw the torch in his hand into the sky during the last stretch before reaching the torch, and then the camera turned to In our space station, the astronauts inside press the sacred button at this moment, the laser transmitter starts, and a laser falls from the sky, falls on the prepared sacred flame, and ignites the torch directly."

"This idea is not only creative, but also has a good meaning! The Olympic spirit that represents mankind is not only on our earth. Human beings will one day be able to enter the infinite space and travel in the universe! So this space relay Is it eye-catching enough?! Wait, let me do the math. If you want the laser to be ignited from 350 kilometers away, it can still maintain the energy level required for ignition... No, no, such a laser generator consumes too much power. , it is impossible for the space station to be equipped with such a big thing, it is not realistic."

Fortunately, Ning Wei denied it, which allowed Liu Wei to take action.

"But if it's just an ordinary visible laser, it doesn't need that much power. As long as it's visible light that can be sensed by the laser. Brother Liu, think about it. Is this okay? We are in China along the coastline and in the border areas. Set up a batch of lasers. The first beam of light from the space station activates the first ground laser, and then the first laser lights up. Then in a certain order, the outline of China is drawn, and finally it is transferred to the capital, and then from the Bird's Nest. The laser lights up the sacred flame. How big of a scene will it be? If you add a signal from a satellite shot to the scene, it will definitely be very impressive, right?"

Liu Wei turned his head and looked at Ning Wei inexplicably. He admired the calm tone in Ning Wei's mouth...

"Based on my knowledge, the laser travels in a straight line, right? And there can't be any obstruction in the middle..."

"This involves a calculation problem, which happens to be the strengths of March and I. As long as there is enough height, it is completely achievable. However, it requires the cooperation of the surrounding provinces and cities. As long as we have the specific altitude of the highest building , and then after calculation, it’s not a big problem.”

"What about the issue of accuracy? The distance between each laser is often hundreds of kilometers, so a difference of just a few centimeters is a thousand miles, right?"

"Precise calculations happen to be the field we are best at. All lasers are angle-controllable and are uniformly controlled by March. Moreover, they must be tested before. Testing and collecting data during the day will have no impact at all."

"This cost issue..."

"It's not that high. It means setting up a dozen lasers. What a good meaning. Let's frame China and no one will be greedy! Don't worry, I personally don't think it's a big problem. I'll simulate it when I get back to the office. If possible, we can Do it!”

"Oh..." Liu Wei thought for a while, and then said sincerely: "Academician Ning, I want to ask you a favor."

"It's not Brother Liu, why are you so polite all of a sudden? What are you asking for?"

"No, I really have to beg you for this, can you promise me?" Liu Wei stopped and looked at Ning Wei very seriously and said.

Ning Wei looked at Liu Wei in surprise and replied angrily: "Okay, you say it!"

Liu Wei cleared her throat, and then said word by word: "You can report this yourself, but don't say anything about what we talked about on the road today. Don't be told that I reminded you of the space station, let alone what I told you. The final stage of the Olympic Games opening ceremony is the lighting of the torch. In short, when you propose this plan, you must say that everything was your own idea and has nothing to do with me, okay?"

Ning Wei blinked. Really, he had never seen Liu Wei so sincere.

"Is this so terrible?"

"Haha... It's nothing to you. If any boss thinks that you can have such a terrible idea, it's me who is fanning the flames behind your back. It will have a huge impact on me. If you don't want me to be transferred directly from my post, If so, just promise me that when you go to discuss it with Director Chen, you will never say that you discussed it with me!"

In front of the building where the office is located, Liu Wei warned him very calmly.

Ning Wei nodded thoughtfully, then smiled and said: "Brother Liu, I understand, I probably understand what you mean. In fact, I also understand that the world in each of our eyes is different. I and I Director Tian sees the world differently. The world in the eyes of scientists and ordinary people is different. The world in the eyes of science and engineering students is different from that in the eyes of liberal arts students. The world in the eyes of politicians and writers is even different... No one can see the world clearly. , of course including me..."

"So I understand what you mean. Don't worry, this matter has nothing to do with you. It's just that things have come to me, so I have to do this well. This is just an idea. It doesn't matter if it can be accomplished or not. Isn’t it a loss?”

Liu Wei smiled bitterly and said, "Mr. Ning, you are good at everything, but you are too courageous."

Ning Wei smiled and said: "Brother Liu, I just think you are complimenting me!"

…

The conversation with Liu Wei made Ning Wei feel that this should be done.

So when he returned to the office, Ning Wei called up March, and then began to use March's huge computing power to simulate the feasibility of the entire idea. About three hours later, Ning Wei got the results. If the whole process was controlled by March, there wouldn't be a big problem. Keeping the network open is the key, but the cost is not high. Of course, there are also requirements for the sensitivity of the laser. Three Monthly recommendations were also given.

By the way, March also gave a number of optical connection patterns to choose from. Simply put, it is a matter of setting up several lasers. Setting a few more can make the pattern look more delicate, and setting a few less can highlight the grandeur. Of course, different plans require different costs. Ning Wei took a quick look and found that they were all within control. According to Chen Wenwen, such expenses are probably ignored.

At least it's much lower than the cost of buying a set of holographic equipment for the opening ceremony. The key point is that it requires a high degree of cooperation from the space station. It must arrive at specific coordinates at a specific time and at a set angle, and then emit that light.

In addition, the shooting angle of distant views is also a problem. However, you can directly connect to satellite signals during live broadcast. In areas with too thick clouds, you can use drones or helicopters to shoot. In general, although there are many problems, as long as there are two months The time is enough to arrange everything clearly.

The biggest advantage is that Ning Wei does not need to study the opening ceremony plan that has been prepared before, because it has no conflict with the original plan, but only changes the final step of lighting the torch.

So Ning Wei was too lazy to waste time and ordered: "In March, make this into a plan and then upload it to my mobile phone. I will send it directly to Director Chen."

A simple and direct way to deal with it. After all, he has to have dinner with Tim Cook in the evening. It takes a lot of brains to discuss things with the elderly while eating. This matter should be over quickly. He still has to take the students to the future city for vacation, which is related to his credibility.

As for the plan if it doesn’t pass...

Then let's wait until he's on vacation before trying to figure this out. After all, he's not a god, right?

…

When Chen Wenwen received the document from Ning Wei, he was stunned.

How long has it been? Less than four hours, right?

Sure enough, what scientists need to think about is indeed different from what ordinary people need to think about.

I opened the document with great longing, read it carefully, and then closed my eyes.

As Ning Wei said, the world in everyone's eyes is different, and each plan is also different in the director's eyes.

With such a macro plan, when each light is on, which angle should be used to shoot to show the best effect? ​​How many cameras are needed, how many helicopters or drones are mobilized, what will be the shooting effect, and what should be chosen? BGM is more suitable...

Then go through the scene after the successful presentation in your mind.

As for whether it's a big problem to play like this...

Well, this is the plan given by Academician Ning. Since Academician Ning thinks it is feasible, he has to report it to everyone first and ask for everyone's opinions, so Chen Wenwen immediately replied: "Received, we will discuss it in a group this afternoon and report it. But Academician Ning, is there really no technical problem?"

"We did a rehearsal and there were no major problems. Three months is enough time to set up all the equipment and complete debugging."

"Thank you! If possible, you will be the commander-in-chief of this link!"

…

After temporarily settling Chen Wenwen's request, Ning Wei received a call from Tim Cook.

The place for dinner in the evening has also been arranged. It is at the Western Restaurant of Boya International Conference Center. It is very close and does not take too much time to get back and forth.

According to Liu Wei's suggestion that you should have a certain amount of exercise every day, it would be a good choice to take a walk there and then back home. It was almost time to set off.

There are so many messy things, Ning Wei has the illusion that he is either eating or on the way to eat every day.

When he walked into the restaurant, Tim Cook and his friends were already there.

"Ning, please sit down. It seems like we haven't had a face-to-face chat like this for a long time, right?"

"Haha, Tim, if you want to chat with me often, you can consider settling in the capital after retirement..."

"I will consider it if necessary. Okay, we all know each other, so don't be polite. It's almost time to serve the meal. Let's chat while eating. Mark specially brought a bottle of wine that is said to be very expensive..."

"Yes, the red wine produced by Lehua Winery's Musigny Grand Cru. Believe me, drinking it is really a pleasure..."

"Ha, um, Mr. Zuckerberg, is this wine sweet?"
