The auditorium of Tsinghua University was full, and the fresh faces were looking forward to it, Lin Han could sneak out from a corner of the backstage, and the overwhelming crowd made him a little nervous. Pen, fun, pavilion www. biquge。 info

"Pursuing progress and academic listening, welcome everyone to Tsinghua Auditorium. Before that, we are sorry to inform you that Professor Zhai Zhilin was hospitalized due to acute appendicitis and could not arrive at the lecture site, and we wish Professor Zhai a speedy recovery.

Today's speech is Mr. Lin Han, a famous science fiction writer and film director, whose science fiction novels have taken the world by storm and has just won three nominations for the Hugo Awards, so let's welcome Lin Han!"

As soon as the host's words fell, the group of intellectuals in the audience exploded in an instant, is this teasing them?

Professor Zhai can't come, but he can't just find a science fiction writer to save the day, it's like going to a French restaurant and ordering foie gras, and the spicy noodles are served.

The overwhelming boos rang out, and the relatively closed environment of the auditorium suddenly became extremely noisy, and it seemed that intellectuals also liked to express their feelings in this way.

The students in the back row were all surprised, "What is this about, let science fiction writers give us speeches and teach us how to write novels?"

"You still don't listen to this lecture, I want to leave. Any garbage can come to our Tsinghua side to give a speech, and it doesn't depend on whether you have the strength to do so. ”

"It's all here, just wait and see what he wants to say. ”

"Wow, it's really Lin Han! I especially like to read his novels, I rarely write soft science fiction, I always write hard science fiction, didn't I just read "The Martian" a few days ago? That's what he wrote, I'll go to him for an autograph later, will you go?"

"Science fiction writers give speeches, and the audience is physicists and astronomers, which seems to be a bit reversed!"

Li Wenyuan naturally heard very clearly in the audience, and he looked at the people in the popular science writers association not far away with some annoyance, everyone is from the same association, even if they don't help each other, they actually hurt people with secret arrows.

That group of guys was waiting to see Lin Han make a fool of himself with Erlang's legs crossed, and he really didn't hide it at all, and he looked like a scum.

The smile on Zhou Qi's face couldn't be hidden, "That kid thought that he could write two science fiction novels and go to heaven, but his mind was too impetuous, and now he actually ran up to give a speech without his own strength, and some of them looked." ”

"I don't have any self-knowledge, and I'm going to lose the face of a science fiction writer. ”

"That's not it, it's a young man after all. ”

Li Wenyuan silently drew a clear line with this group of people in his heart, it was obvious that these people stabbed Lin Han out, but now it has become Lin Han's, and his posture is disgusting!

The original boos reached their peak when Lin Han appeared, and a handsome young guy actually stepped into the position of the speech!

Although he didn't shave his beard in the morning and deliberately walked in the direction of maturity, he looked like he was about thirty years old, and the scientists were all old.

It seems that Lin Han, who walked on the wrong set, stood on the podium, he didn't have any manuscript on the table, and everything had to rely on himself.

"Good morning, I was actually just here to listen to the speech, but now I am standing on the stage. I mean, hey, I've got a seat on row 7 in row 14, and you can sit down with the student crouching at the back. ”

As soon as Lin Han came up, he complained briskly, and did not directly say anything at length, the atmosphere eased slightly, and a burst of laughter made the student blush.

With Lin Han's words, everyone turned their heads to glance at the figure who trotted from the back to the front and sat down, this was actually Lin Han narrowing the distance between the two sides: See, we are here to listen to the speech like you, but there was an accident.

"Actually, the topic of my talk today is not advanced physics, but 'How Humans Will Survive on Mars?' and some of you may know that I wrote a novel called 'The Martian', which tells the story of an astronaut who is trapped on Mars and saves himself. In 20 years, will we be able to land on Mars and live there?"

"Now everybody get ready, we're going to Mars! It's not just astronauts, it's thousands of people who are ready to colonize Mars, and believe me, it's going to happen in the near future. Perhaps some of you will stay on Mars to work, and I guarantee that your children will have the opportunity to stay there as well. It may sound ridiculous, but I'm going to share with you how and when it happened!"

Lin Han's choice of speech topic is closely related to his novel, which will not go too far beyond his knowledge level, if you directly take Hawking's speech about black holes and a brief history of time, it will directly cause a sensation.

Half a step ahead is a genius, and then it is a madman, everyone knows that a film director cannot have such a profound knowledge of physics, and he will definitely doubt Lin Han's identity and bring him a lot of unnecessary trouble.

Talking about the survival of Mars, others will not have any doubts, they will think that it is the knowledge and ideas he accumulated when writing novels, and he can also advertise the novels by the way.

Using Tsinghua University's speech to advertise is probably the most high-end.

In front of such a large audience, Lin Han did not show timidity, he said eloquently: "First of all, I want to discuss an obvious question: why do we do this? Our earth is really incredibly fragile in front of the whims of the universe, and a single slightly larger asteroid can make us disappear forever. In order to survive, we must have a backup planet. There's another reason why we should do this, because we're born with the courage to explore, and it's the genes that are in our DNA.

……

As you can see, Mars is not like Earth, but it is the most inhabitable place in the entire solar system except Earth. But there is a problem here, the distance to Mars is a thousand times the distance between the Earth and the Moon.

Mars is 400 million kilometers away from the Earth, and it takes us a full eight months to reach it, and we only have two opportunities a year to land at a special time on this special day when the Earth and Mars are in a line, because this is when Mars travels the shortest distance. ”

Lin Han's speech was subdued, but he rushed into battle without preparing suitable demonstration pictures, otherwise the audience could feel the meaning of his words more intuitively.

Originally, the audience who were shouting to leave the venue had quieted down, and began to seriously think about the content of Lin Han's speech, and devoted themselves to thinking.

As for the foreign physicists in the front row, they were wearing translation headphones, and they were very surprised and said to the Chinese scientists around them: "Wow, are all your Chinese science fiction writers so powerful? It's unbelievable!"
