Tech Hammer

This is exactly what happened.

This global live broadcast has been going on for about ten minutes, and countless extremely important phone calls around the world are ringing one after another.

God knows how many big names quickly turned on various devices and started watching the live broadcast after receiving the call. There are more people who have to rush to work after get off work because the next tasks are actually very heavy. Some people want to check the authenticity, some want more information, some people feel that they may not be able to sleep well if they read this at night, and they also have to make others unable to sleep well...

Of course, the biggest emotion is shock.

Shocked by these pictures and the unknown details hidden behind these pictures.

High-rise buildings cannot be built in a day. The taller the building, the more stable the foundation needs to be. What can be put on display for everyone to see is far from the scariest thing. The really scary things are those things that are hidden and hidden from others.

Taking a step back, in this era where countless disciplines are related, the technology involved in sending a large platform comparable to an aircraft carrier into the sky is terrible. As long as you have received nine years of compulsory education, you know that the earth is round and understand gravity. Anyone with an acceleration equal to 9.81m/s^2 can think of it as long as they use their brains.

Just like that, under the eager anticipation of everyone, the live broadcast screen finally switched to the Mir.

…

"Hello everyone, I am Tan Shuang, the ship's reporter for this live broadcast. I am standing on the Mir, which is undergoing its first trial voyage. This is the crew rest area of ​​the Mir, and it is also the layer closest to the deck. Everyone You can see that the space here is very huge, and there are no common load-bearing columns inside, but a large open place.”

The camera began to slowly pan through the interior of the fifth-floor ship. At this time, the reporter's location was indeed very large, as large as a football field. It is divided into several leisure areas. The whole space is still an open space. There are already some internal staff sitting at the place where drinks are provided and drinking coffee, but more people are still looking out at the railings at the edge of the ship.

"I am really excited at this time. Because before boarding the Mir today, I did not expect that this aerial mobile operating platform would be so huge! Please forgive me, I can only use the word huge to describe it. There is no real You can't experience the shocking feeling standing up here. Now we are cruising at an altitude of about 6,000 meters, and you can see that Mir is surrounded by clouds..."

The camera was focused on the outside of the cabin. It was actually similar to what you saw on the plane. There were stacks of white clouds below. But it’s not like you can only look at the sky through a small window on an airplane. The overall transparent outer wall allows people to have an unobstructed view of the high-altitude scenery.

The broad field of vision makes people feel relaxed and happy, as if they are really in the sky.

"I have noticed that netizens on the live broadcast have many questions, but unfortunately Mir is about to conduct a rescue exercise. As the chief designer of Mir, Professor Luo Zhiqiang needs to personally direct the exercise, so he is not available to accept us for the time being. An on-site interview. However, we are fortunate to invite Dr. Cheng Xiaolu, a student of Professor Luo and the publicity ambassador of Mir, to popularize some basic information about Mir. You can also ask questions in the barrage, and valuable questions will be Select it, and then Dr. Cheng will answer your questions."

After the words fell, the camera began to move back, and then Cheng Xiaolu and the reporter appeared in the shot. At this moment, Cheng Xiaolu gained enough exposure that many people would envy. Even though the live broadcast did not attract such a large amount of attention at the beginning, it is no exaggeration to say that at least one fifth of the people in the world are paying attention to this live broadcast at this moment, and at least the group of people at the top of the pyramid in various industries around the world are paying attention to it. Ninety percent of it is deep attention.

This kind of treatment is really not something that an ordinary doctoral student can enjoy.

"Hello, Dr. Cheng."

"Hello Reporter Tan, just call me Xiaolu."

Cheng Xiaolu, who was on camera for the first time, flipped up her hair in order to relieve her nervousness.

"Okay, Xiaolu, you should have seen it on our live broadcast just now. Our netizens were very excited to see Mir take off. Now everyone is very concerned about some basic conditions of Mir. You Can you briefly introduce it to our netizens?”

"Okay, Reporter Tan. Now let me introduce to you some basic parameters and first-hand data of Mir."

I have to say that Cheng Xiaolu is still very photogenic, especially because she has a good psychological quality and does not have any stage fright when facing the camera: "Our Mir is up to 1,776 meters in length, the available deck sliding length is 1,667 meters, and the widest point is 583 meters. , the maximum height from the bottom to the top of the command tower is 46 meters, with an average height of 38 meters. In the words of netizens, he is a real big guy."

"The maximum load capacity of Mir is 65,000 tons, which is roughly equivalent to the displacement of a medium-sized aircraft carrier. But our Mir is actually very different from the aircraft carrier. I used my teacher, Professor Luo, who is also the chief designer of Mir. In other words, Mir is actually an empty frame. Academician Ning, Mir’s chief scientist, also agrees with this statement and said that the most advanced thing about Mir lies in the main materials it uses.”

"For example, Mir's power system is actually a very common electric drive technology in the laboratory. At the same time, Mir's simulated gravity system is also very crude and can only affect the area inside the control tower. Therefore, Mir does not have the ability to stay in space for a long time and realize space exploration. The ability to transport over long distances…”

"Ah, wait, Xiaolu, I'm sorry, let me interrupt. What you just meant is that our Mir still has the ability to travel into space?"

"Yes, Reporter Tan. Mir can stay in space for a short period of time. According to current standards, the maximum stay time in space is recommended to be no more than 100 hours. In extreme cases, it can stay for 135 hours, which is about six days. Look."

"Oh my God, do we have any plans to enter space today? To be honest, this is really exciting. After all, being able to enter space is still very desirable for an untrained ordinary person. I believe that the majority of netizens It must be the same for us, right?"

Cheng Xiaolu smiled and said: "Well, today's live broadcast plan includes a plan to enter space orbit. We will return to the atmosphere immediately after orbiting the earth once in low-Earth orbit. This is part of this voyage test. But unfortunately, For safety reasons, all staff, including myself, who have not been trained in the weightlessness of space will be evacuated by aircraft before Mir enters space."

"Ah, this is such a pity. Well, then you go ahead, Xiaolu."

"Well, I just mentioned that the Mir serves all mankind. Academician Ning Wei specifically mentioned this during the video conference. The biggest difference between our Mir and the aircraft carrier is that the Mir is a civilian ship. In addition to constantly testing performance, the most important role is to improve the happiness level of all mankind for the benefit.”

"So the most important missions Mir will undertake in the future are rescue, transportation, scientific research, and space services. Rescue is mainly for civil aircraft when they encounter emergencies in the air. Our Mir can provide air rescue; transportation is mainly for ground and air. Transportation, as we just said, Mir has the ability to stay in space for a short period of time, which gives Mir the ability to deliver satellites."

"Based on the maximum stay in space of one hundred hours, combined with Mir's load capacity, we have the ability to deliver hundreds of satellites into predetermined orbits at one time. At the same time, we can also provide a repair and maintenance platform to complete satellites, space stations, and The task of transforming and repairing telescopes can greatly extend the use time of various space satellites. At the same time, we can also provide old satellite recycling services."

"In addition, the most important function of Mir is to serve as a large-scale international responsive disaster relief platform for the future. The ultra-long endurance and support capabilities give Mir the ability to respond ultra-fast and deliver globally. The specific performance is in receiving After receiving disaster information, it will arrive at the disaster scene as soon as possible, no matter where the disaster occurs. After Mir arrives, it can establish a temporary but reliable communication network for the disaster area as soon as possible, and by exploring the surrounding area, it can determine possible disasters as soon as possible. Secondary damage and providing early warning.”

"At the same time, the Mir itself can also provide emergency relief supplies and crisis rescue centers to disaster areas during emergencies. If conditions are favorable, it can also transport the injured to the Mir for emergency medical treatment and transfer services. These are also the things that Academician Ning and The original intention of all the staff of our Qingshan Research Center in designing and building Mir. Of course, we will seek local consent before providing these services to countries and regions outside China."

"It's so amazing. Some of our netizens asked, the moment Mir took off, it was like clouds and mist steaming. Is there any explanation for this?"

"Oh, because Mir is a large-scale civilian aerial work platform. Under normal circumstances, we will not carry weapons on voyages, so we need to have certain self-protection capabilities. Therefore, Mir emphasized its stealth function at the beginning of its design. In During the live broadcast just now, everyone saw a cloud rising from the mountains, which is actually one of Mir's stealth capabilities. At the same time, its body can also filter multi-band radar waves."

"In this way, Mir can avoid unnecessary troubles during its daily patrol. These are all security efforts to better serve people around the world. Of course, even if we encounter a real threat of force, we will Don’t be afraid. In an emergency, we can quickly enter space to avoid some possible attacks."

"Of course, netizens please rest assured. Although our Mir mainly serves everyone, we also have comprehensive considerations in protecting our own safety. There are not many weapons on this planet that can really pose a threat to Mir. . And even in the most dangerous situation, all personnel on Mir will have enough time to safely evacuate with the vehicle, and have the ability to independently choose the crash site under any circumstances."

"Um...choose the crash site on your own?"

"Yes, in fact, if Mir is decommissioned normally in the future, it will enter space and fly towards the sun under automatic control according to the original design, which will not cause any burden to the earth. But if it crashes in the atmosphere due to an accident, because of the material of Mir itself, Due to its particularity, the consequences may be dire. Fortunately, according to our deductions, Mir's self-protection ability allows it to use its intelligent mode to ensure that the crash site it chooses will minimize the loss to China no matter how critical the situation is."

how to say……

This is really a very high level statement. As for where the crash will cause the least damage to China, that is a matter of opinion...

There are many directions for understanding. However, this question is actually very similar to a brain teaser that has been circulated among student groups for many years. Are you not afraid of where pimples appear?

Basically, the most standard answer is probably that I am not afraid at all if acne appears on other people.

"Woo..."

Just as Cheng Xiaolu finished speaking, the alarm in the cabin suddenly sounded. Everyone immediately started moving and gathered towards the stern of the ship. Cheng Xiaolu was not in a hurry when she arrived, and continued to speak to the camera calmly: "This is an alarm signal that today's rescue drill is about to begin. Notify everyone and the crew to get back to their positions. We just We need to rush to the relatively safer control tower within ten minutes."

"Of course, this rescue exercise is mainly to simulate the aerial rescue operation carried out by Mir after receiving a business jet facing double engine failure in the air. The whole process will also be broadcast live to all viewers. Next, everyone will see the entire rescue process."

"Okay, thank you Cheng Xiaolu, then please continue to pay attention to the Mir rescue operation. Thank you for your attention."

When Reporter Tan finished speaking, the signal simultaneously switched to the picture of Mir flying through the clouds.

…

International Mathematics Research Center, Yanbei University, Beijing, China.

Ning Wei, who was sitting at his desk, raised his hand and turned off the synchronized live broadcast after seeing the screen change.

We came to the conclusion that the child Cheng Xiaolu performed well. Therefore, there is no need for him to watch the next rescue drill. It is meaningless. The entire rescue process has gone through many animation simulations in March. He has watched it many times. Basically, all possible emergencies have been considered. Here we are, the probability of something going wrong is really low.

Not to mention that this exercise is somewhat of a performance. The rescuers, pilots, and crew members participating in this exercise are all carefully selected professionals with top professional abilities and extremely strong psychological qualities. Ning Wei even doubted that even if the two engines stalled in the air, the pilots in the exercise could successfully make an emergency landing.

Not to mention that for the sake of safety, the aircraft used for this exercise was a Gulfstream series of business jets, so there was almost no difficulty. If Ning was given a choice, he would prefer to go directly to Boeing.

It's not interesting anyway, and he has to go to the Centennial Auditorium, and he will have to face questions from a group of curious babies later.

Picking up the phone, I glanced at it and saw more than a dozen missed calls. Ning Wei smiled and ignored it. After all, he didn't know what to say now. So he naturally put his phone in his pocket and slowly walked out of the office.

The weather is fine today in Beijing. Even Comrade Xiao Yuan who is waiting outside looks quite handsome. Perfect!

"Let's go!" Ning Wei waved to Xiao Yuan and took a step forward with great satisfaction.
