Qin Guan was stunned for a while, and Dr. Bull actually pointed out that this Star Wars is a hoax?

Now, who has the courage to say that Star Wars is a hoax? Even the Xiong people took it seriously and began to intensively formulate a plan to fight each other. Dr. Bull is too eloquent, right?

"Back then, in order to land on the moon, Eagle Country launched more than a dozen Saturn Fives in one go. What was the result?" Dr. Bull said: "After that, no one is interested in the moon, or it is simply not worth the loss. The investment is too high. If it continues, it will severely drag down the country’s economy. Now, if they want to deploy so many space weapons, they may have to launch more than ten Saturn five-level rockets a year. The U.S. economy will definitely suffer. The actor president will certainly not do that if it is worn down, unless he is really stupid."

Dr. Bull looked out the window: "If I use my super cannon to launch it, it's almost the same. Compared with this chemical rocket, my cannon is much cheaper."

Qin Guan said an electromagnetic gun, and Dr. Bull thought it was impossible. The weapons in Star Wars were all too science fiction.

Qin Guan shook his head: "Doctor, the advancement of science and technology develops exponentially, just like a technological explosion. You can imagine what the world was like a hundred years ago, when cars were sluggish. Like a snail, there is no current airplane or rocket. Our technological progress in this century is equivalent to the technological progress of the past two thousand years, or even more!"

What Qin Guan said, let Dr. Bull put down his pen and poured it seriously. It sounds like, yes, the development of technology is quite fast. Compared with a hundred years ago, this is definitely an unimaginable era.

Now, it seems to me that those Star Wars plans are all science fiction, and they are all flickering, but who would have thought that in ten or twenty years, these technologies will not break through?

"The energy of gunpowder is limited, and it has basically developed to the limit now, just like bows and arrows and crossbows in ancient times. When they develop to the extreme, they will inevitably call for the emergence of new technologies and the use of gunpowder. Ending the bow and arrow and the crossbow machine, maybe in the future, the electromagnetic gun will end the current artillery, Dr. Bull, if you want to realize a super cannon, do you say, gunpowder and electromagnetic gun, which one has more potential?"

Qin Guan said it seriously.

Electromagnetic gun, is it science fiction? It sounds like science fiction now. After all, although the principle of electromagnetic guns has existed since the last century, there is a big difference between theory and practice. During industrialization, many problems will be encountered.

During the Second World War, some countries were conducting research, but they all failed without exception. The final result was that Hansley of Hansland accelerated the 10-gram projectile with electromagnetic guns to a muzzle velocity of 1.2 km/s.

After that, various countries were still developing it. Until the 1970s, Yangbei Guo accelerated the 3g projectile to 5.9 km/s. This achievement proved experimentally that it is feasible to use electromagnetic force to push objects to ultra-high speeds.

After that, the military of all countries around the world paid attention, and the Eagle State Ministry of National Defense established the "Electromagnetic Gun Joint Committee" to coordinate the scattered research work of electric guns conducted by the army, the Ministry of Energy, the National Defense Atomic Energy Agency and the Strategic Defense Initiative.

In 1980, the experimental electromagnetic cannon built by Westinghouse for "Star Wars" accelerated a 300-gram projectile to about 4 kilometers per second, and in a vacuum, this speed could be increased to 8-10 kilometers per second.

Although Star Wars has many fake projects, this electromagnetic gun is definitely real.

The research and development of electromagnetic guns will also lead to many technological advances, such as the research and development of superconductors, and so on. In this way, it will also bring results to other industrial applications, such as high-speed railways, which require this superconductor technology.

Qin Guan was fooling around. Such a genius would be a pity if he only came to study chemical guns. If he could transfer his interest to electromagnetic guns, it might be possible for Han to make electromagnetic guns practical.

In later generations, it was not until 2020 that these technologies gradually developed. Both the Han and the Eagle countries have already had the first batch of electromagnetic guns into service. This is a huge development.

The principle of the electromagnetic gun determines that it can be easily converted into an electromagnetic catapult, and after it is enlarged, it can even launch a spacecraft, and so on.

Dr. Bull didn't speak, he used a pencil to write down the electromagnetic cannon solemnly on the paper just calculated. Now, he has begun to be interested in this type of cannon.

That's right, Qin Guan's words moved him.

Qin watched that Dr. Bull had been persuaded, and finally felt relieved. If Dr. Bull was willing to work **** the electromagnetic gun, he would of course invest a large amount of money to provide support. Anyway, he has a weapon cemetery.

Watching Dr. Bull's input, Qin stood up and walked towards the back. In the economy class behind, many people were already asleep, and his parents, who were cuddling together, were already asleep.

Chen Yutong was in the seat behind his parents, watching Qin Guan come over, and said, "Are you finished?"

"Yes, there is a lot of work." Qin Guan sat next to Chen Yutong. Even on the return flight, he still needs to work. After returning to China, there are still many things waiting for him.

"Brother Guan, our children have also grown up gradually. I think I should also be at work. After I return, I want to study heart transplantation with my parents."

Chen Yutong studied medicine. In the past, he could only be a little doctor in the factory's health clinic and do some preliminary medical treatment work. It would not work if it was too complicated. However, after all, he had the foundation to study medicine. Now, Qin Guan's parents are going back to China. After they return, they will definitely become the country's authority on heart transplantation. Chen Yutong will be able to learn first-class medical skills with them.

Qin nodded his head: "Yutong, thank you very much."

Of course Qin Guan knows Yutong's true purpose of studying medicine. For a couple, if both of them are busy with their careers, then the education of their children is a big problem. Therefore, one person will take the initiative to sacrifice his career to take care of the family.

Qin Guan is a busy man. In these years, Chen Yutong has been responsible for almost all his family. Chen Yutong has hardly worked properly in these years, just doing miscellaneous tasks for Qin Guan’s company. Now, Chen Yutong is going to work. There is a purpose.

How many years can the mother's heart transplant survive? How to maintain the best? Is there a better specific medicine? Chen Yutong said to learn medical knowledge in this area, in fact, to help her mother.

Otherwise, she would not have to step into this field at all.
