Open an aircraft carrier to fight against Japan

The sound of the erhu, yes, the sound of the erhu.

Lin Yuan looked at Zhang Yi in surprise, pointed to the castle piled up with books and manuscript papers and said, "Is the person inside Einstein?"

"That's right, Einstein."

"When did Einstein play the erhu? In our era, didn't he play the violin?" Lin Yuan lowered his voice, for fear of being heard by Einstein. In Lin Yuan's time, Einstein was not only a big A scientist, and a violin master.

Zhang Yi shrugged his shoulders and said with a smile: "No one plays Western musical instruments now, but there are many talents who play Erhu, Pipa, and Sanxian." Zhang Yi is right. Under the influence of China's strong national power, there are very few musical instruments in Western culture. Some people have played it, and Chinese traditional culture has the widest audience.

The whispering between Lin Yuan and Zhang Yi was heard by Einstein in the "castle". He stopped his erhu and poked his head out, his eyes just collided with Lin Yuan.

The Einstein in Lin Yuan's impression is full of wrinkles, with a big back and a mustache. His hair and beard are both white. This is the standard portrait of Einstein in Lin Yuan's era, but the love that Lin Yuan saw at this time Einstein, however, has a neat cropped cut and a fair face.

It turned out that the portrait of Einstein that Lin Yuan saw was left after he was 50 years old. Now Einstein is only 23 years old, and Lin Yuan is 36 years old. He looks much older than Einstein.

When Einstein saw Lin Yuan, he didn't recognize him. The person Einstein recognized was Zhang Yi. He stood up, stepped out of the castle, walked up to Zhang Yi, and called out "Hi, teacher. ", speaking fluent Chinese. In this era, all scientific and technological materials are in Chinese. If you want to learn, you must first be proficient in Chinese.

Zhang Yi pointed at Lin Yuan, and said with a smile, "This is Lin Yuan."

Lin Yuan smiled and nodded, and was ready for Einstein to scream, tremble, or even kneel down. Most people do this when they first see Lin Yuan, because Lin Yuan is a god in their hearts, but But Einstein said indifferently, "Hello Lin Shuai", then turned his head to look at Zhang Yi, and said coldly, "Teacher, if it's okay, I'm going to study."

Einstein was about to leave after speaking, but Zhang Yi hurriedly stopped him, "Don't leave, Shuai Lin is here to listen to your report on the research situation."

Einstein glanced at Lin Yuan contemptuously, and said disdainfully, "Does he understand?"

Zhang Yi frowned, "Don't be rude to Lin Shuai."

Lin Yuan laughed, "Don't be angry. I think Mr. Einstein has a very good personality. Geniuses are like this. Mr. Einstein, tell me about your research results. I should be able to understand you."

Einstein snorted coldly, took out a book from the castle, opened a page, handed it to Lin Yuan, pointed to the page and said, "Solve this problem, and I will tell you."

Lin Yuan looked in the direction of Einstein's finger, and saw that his finger was a math problem, in the category of functional analysis. Lin Yuan's math level is quite high, so he took the book and said with a smile: "This problem It's not complicated, it's just that the calculation is a bit cumbersome, without a calculator, hand calculations are very troublesome."

"Just tell me the solution."

Lin Yuan explained the solution again, and then Einstein smiled a little, "It seems that you are not scientifically blind, very good, what do you want to know, just ask."

"I heard from Zhang Yi that you are studying time travel?"

"To be precise, what I study is time and space. If you insist on time travel, you can barely do it."

"Well, let me ask the first question first, what conditions do you think allow a person, or a group of people, to travel through time and space and go back to the past."

Einstein shook his head with a smile, "Going back to the past is wrong in itself. You can't go back to the past. If someone can travel through time and space, then he will go to another brand new time and space."

"Parallel time and space?" Lin Yuan asked tentatively.

"It can also be said that according to my calculations, time and space can be multiple, and a person can enter another time and space from one time and space."

"Then what conditions can complete this kind of time travel?"

Einstein shook his head sadly, "I don't know, I really don't know. I have made many conjectures, but none of them can be confirmed by experiments. Those hypotheses can only be hypotheses."

Lin Yuan sighed softly. For so many years, Lin Yuan has always wanted to know what it was that made them travel through in the first place, but this matter surpassed the sum of the knowledge of Lin Yuan and all the experts of the Beijing Ship, and Lin Yuan was really helpless.

Lin Yuan thought of another question that he was very concerned about, that is - he and the Beijing ship traveled through time and space, whether the Beijing ship can return to the original time and space, the Beijing ship is impossible for China in Lin Yuan's era Indispensable strategic force, not to mention that there are a large number of experts in various fields on board the Beijing ship. The Beijing ship disappeared with so many experts. What will China do in Lin Yuan's era.

Even if Lin Yuan doesn't consider such big issues as what the country should do, he still has to consider personal issues. For example, all the people on the Beijing ship have families, and their sudden disappearance must be unacceptable to family members.

Lin Yuan then asked: "If a person travels through time and space, is it possible for him to return to the original time and space?"

Einstein's expression darkened suddenly, and he shook his head silently, "I don't know about this. In the universe model I established, it may or may not be possible to return to the original time and space."

Lin Yuan was most concerned about the two questions, one was the reason for time travel, and the other was whether he could go back after time travel. Unfortunately, Einstein did not give a satisfactory answer.

Einstein was a little annoyed when he saw Lin Yuan asking two questions that he didn't know. He said anxiously, "Shuai Lin, do you have any questions? If not, I'm going to study it."

Einstein's tone is very urgent, and the voice-over is - Lin Yuan, you should go now, don't bother me, I don't want to talk to you anymore.

Lin Yuan was not angry, but just smiled lightly and said, "Well, you should hurry up and study."

Einstein pointed to the door of the room, and said coldly: "You are in my laboratory, please leave my laboratory, otherwise I cannot study."

Lin Yuan cheerfully took Zhang Yi out. Zhang Yi looked back at the closed door, sighed, and sighed: "When I look at Einstein, I see myself at the age of 20."

Facing two lunatic-like geniuses, what else could Lin Yuan say. He didn't say anything, but changed the subject: "Let's go, let's go to the Institute of Genetic Weapons."
