Today is Saturday, and the freshmen in the Department of Aerospace Engineering are very excited, not because it is another weekend, and there is time to play. 35 As the most outstanding students from all over the country, there is still self-control. Besides, just entering the university gate, these students still have a beautiful yearning for the future, not like those old people in their junior year and senior year, who have seen through the world.

These students were happy that a great man would come to give them a lecture. This is indeed a powerful and inconsistent figure. As the chief engineer of manned space flight in China, for these students who are likely to engage in aerospace in the future, it is an unattainable existence. For students in this major, he is the existence they most look forward to.

As the first batch of freshmen in the aerospace majors to be admitted to China after the manned space flight, these students have too many imaginations about the future. In the past, they could only envy Uncle Sam and the polar bear for being able to send people into space. However, in mid-October last year, yesterday a year ago, after China successfully realized manned space flight, their dreams were no longer only imagination, but also examples to follow.

It was originally the lecture that started in the afternoon, but at 2:30, everyone could not wait to arrive at the stairs classroom where the lecture was about to be held and waited.

Not only are freshmen from the Department of Aerospace Engineering coming, but some students from other grades and even majors who have received the news also followed. Even at Tsinghua University, it is very rare to give lectures by a great man like Academician Wang. No one who has received the news will miss such an opportunity.

Therefore, when Zeng Lingfeng accompanied Academician Wang to the classroom, he saw that the person sitting in the classroom was not just the Jiusheng in their department, but the full of people in a classroom, with two or three hundred people.

Although he was a little surprised, Zeng Lingfeng still understood it. He had seen such a situation before. No matter what, he was a graduate of a prestigious Chinese university like the University of Science and Technology of China in his previous life, and such a hot scene is not uncommon.

Academician Wang was not surprised by such a scene. He naturally walked to the seat left in the front row of the classroom and sat down. It was not yet time for the lecture to begin.

When the two class teachers saw Academician Wang coming, they came over to say hello to the old man, and the old man also answered politely to the two young men.

When we were three minutes away..., the head teacher of Class 1, Zeng Lingfeng, walked to the podium, held the pre-tuned microphone and said to the students in the classroom: "Dear students, good afternoon, today is the first lecture for our freshman in the Department of Aerospace Engineering. We are honored to invite our Academician Wang to give us such a lecture. This is not only our first lecture, but also our admission education. I hope everyone can listen carefully, understand and understand Academician Wang's lecture. At the same time, we also warmly welcome the students of other grades and even foreign departments who came to participate in this lecture. I hope everyone can abide by the order of the venue. Okay, I won't say much. Let us welcome Academician Wang to give us a lecture with warm applause, everyone welcomes you."

Amid the warm applause, Academician Wang walked to the podium.

"Students, I am very happy to be invited by everyone to give you such a lecture. In fact, this is also an opportunity to communicate with you. The students are the sun at breakfast and their thoughts are active. This is very rare for us old people, so this is also an opportunity for me to learn from you. What I want to talk about today is not a profound knowledge, or some ideas I just had not long ago. I gave it a nice name called "The Imagination of Wandering the Stars". Traveling around the universe is something that every human being is very envious. In fact, this is not an impossible wish. When we have enough fuel to support us in long-distance aerospace, this dream is no longer a dream. Today, the lecture I gave was held on the premise of assuming that we humans have mastered such an energy." Academician Wang said slowly on the podium.

Academician Wang's lecture was indeed very easy to understand, without any profound theoretical knowledge, it was just some imaginable practical things, some things that humans would travel in the vast universe in the future.

The lecture was not very long, just one hour later, Academician Wang ended his lecture and entered the stage where everyone asked questions and discussed freely.

Regarding the series of imaginations mentioned by Academician Wang, Zeng Lingfeng knew that the energy he mentioned was fusion energy. As what humans have learned today can provide the largest source of energy, nuclear fusion is undoubtedly the most practical.

Although it has only been less than a day, Academician Wang seems to have been thinking deeply for a long time. The lecture was full of passion and affection, which is very attractive.

When they entered the free questioning session, the most enthusiastic questioning was not the protagonists of Zeng Lingfeng and others, but the seniors in the senior year, whether from the department or from the outside, the frequent questions they asked far more questions than those of Zeng Lingfeng and others.

"Academician Wang, I am a junior in the Department of Aerospace Engineering. What kind of energy is the magical energy I mentioned many times in your lecture? Is it the energy provided by stars in interstellar space?" A very nice girl's voice was the first to remember. Zeng Lingfeng looked down the sound and said that he was a very beautiful girl, tall and almost 1.7 meters tall. This senior sister Zeng Lingfeng didn't know, but he knew the girl sitting next to her, which was the beautiful senior sister Yang Suqing he met when he registered.

"Haha, this classmate, the energy provided by stars in interstellar space you mentioned can indeed be considered as an energy source. However, this energy is a bit unstable, because in many universes, there are very likely no stars within a long distance. The energy provided by stars in such universes is very low, which is not suitable for interstellar space. In addition, even if we assume that stars in interstellar space are evenly distributed, we also face a big problem, that is, the speed of space tools will be very slow during the initial acceleration. And we all know that interstellar navigation is extremely long-distance, which is very difficult." Academician Wang said.

"What kind of energy is Academician Wang talking about?" the beautiful girl asked.

"Haha, in fact, the energy that this classmate said is essentially the same as the energy I assumed. You may have thought of it, that is fusion energy. Maybe everyone wants to say that the possibility of mastering controlled nuclear fusion is very small, and it cannot be achieved in the expected time. However, our interstellar space is not possible in a short period of time, which is also a long-term plan. So, when we plan interstellar space, why not imagine its energy as controlled nuclear fusion?" said Academician Wang.

"In fact, we humans are a race that is good at creating miracles. Look, we humans have experienced hundreds of thousands of years from the original primitive society to the steam era, but from the steam era to the current highly developed information era, it only lasted two or three hundred years. This tells us a fact that when we humans open a door, everything will develop rapidly beyond imagination. When humans create the first steam engine, no one can imagine that in three hundred years, humans can enter the highly intelligent information era? Similarly, how can we be sure that our humans are in the distant future of mastering controllable nuclear fusion?" Academician Wang looked at the people in the room and said in a affirmative tone.

At this time, another boy stood up and said, "Academician Wang, I am a junior in the Department of Engineering Physics. As Academician Wang said, humans may realize controllable nuclear fusion in a very short time, but as far as I know, some research projects on controllable nuclear fusion in the world, whether international cooperation or individually carried out by some countries, are extremely unobjective, unlike those that can achieve controllable nuclear fusion in a short time. Does Academician Wang have some special channels and know some other news?"

Academician Wang smiled and said, "Student, I can't give you an accurate answer to your questions. This involves state secrets. Before you have enough confidentiality levels, it is better not to ask such questions."

It would be fine if Academician Wang did not answer, but this answer even further uplifted the curiosity in the hearts of the teachers and students present. This question involves state secrets and cannot be asked? Isn’t it very likely that the country really has some secret plans in this regard? And its progress is progressing more smoothly than those known controlled nuclear fusion plans?

This is a question that many people here have.

Zeng Lingfeng smiled bitterly. The old man looked a little like a show-off child, but he was a little bad. This was just to cheer everyone up.

Many students asked some questions later, but with the previous lessons, no one asked whether the country had a secret plan to conduct controlled nuclear fusion research, but they all involved interstellar space or manned spacecraft. As the most outstanding person in China in this regard, such questions naturally would not make Academician Wang too embarrassed. Even for some very rare questions, Academician Wang gave very clever answers.

Soon, an hour passed again, and it was already five o'clock in the afternoon.

The head teacher of Class 2 stood up and said to everyone: "Okay, although everyone is very reluctant to let go, I have to interrupt everyone. It is already five o'clock in the afternoon. Academician Wang has been communicating with everyone for two hours, and must be very tired. Besides, it is already very late now, so this lecture ends here. If you have any questions, you can find an opportunity to communicate with Academician Wang again. Now, let us all give warm applause and thank Academician Wang for this wonderful lecture for us."

There was a wave of applause in the classroom again.

With everyone's applause, Academician Wang bowed to the bottom of the podium, then packed up his things and left the classroom.

After Academician Wang left, other students from other grades and foreign departments also left, leaving behind freshmen from the Department of Aerospace Engineering, and the two class teachers still have some things to arrange.
