Elsa really believed in evil, and after leaving the Liangjiang area, she first took an empty boat to Kaifeng. Pen? Interesting? Pavilion wWw. ｂiquge。 InfoAt this time, Kaifeng was still one of the world's largest cities with hundreds of thousands of permanent residents, and the people Elsa was looking for were called blue hats by the locals. People who live in Kaifeng all year round know it.

After the meeting, although both parties could only communicate in Chinese, the scriptures in the same Jewish script in their hands could not deceive people. The elders here told Elsa that it had been a thousand years since their ancestors moved here. Because no one here discriminated against and persecuted the Jews, their ancestors lived like this.

Regarding the establishment of the state of Israel, the people of Kaifeng were also very happy to hear about it, and the people who have wandered for thousands of years always want to go home. Although the Jews here will not all go back, they can send a group of young men back, and the new Israel will always have to be a soldier.

After a week in Kaifeng, Elsa took an airboat to the school city in Aizu, Japan. Reinforced concrete high-rise buildings, wide highways, huge windmill generator sets, trams shuttling back and forth, and self-cleaning robots. Even the free automatic racking machines for various drinks and snacks along the way, the huge airboat floating in the sky has only one function, telling the time and the weather.

Although some things have spread outside, not every country has capacity building in a modern metropolis of this size, even in the 21st century, - South Africa has not built a single tall building or a decent building since Mandela came to power.

If the construction of the city alone made Elsa feel like she had come to the City of God, what the students discussed here made Elsa even more incomprehensible.

Recently, Lin Haiyang donated a carrier rocket to Gakuen City on behalf of the Japanese government, and the students of Gewu Advanced Class are discussing whether to use this carrier rocket to launch a satellite or engage in the first manned space flight of mankind.

It is still somewhat difficult to launch satellites, after all, satellites need to communicate and be ready to change orbits at any time, etc., and it is expected that it will take several years to build the first artificial satellite. The difficulty of manned spaceflight is relatively low, just design a manned warehouse, and finally recover the landing point of the manned compartment may be difficult, but as long as it is calculated and landed on the sea, it can still be recovered.

Historically, the world's first artificial satellite was successfully launched into space by the former Soviet Union in 1957. The first artificial satellite of the Americans was in 1958. The first Soviet cosmonaut Gagarin went into space in 1961.

The rest is not very credible, and the Americans, 11 years after the launch of the first satellite, sent astronauts to the moon. What is left to the world is a weird video of you not jumping even in the low gravity of the moon.

As for the success rate of the Saturn V launch vehicle back then, it is astonishing, but not a single drawing of the Saturn V satellite jointly developed by hundreds of universities and thousands of enterprises has been left.

According to the speed of the United States, in fact, China and the former Soviet Union, which have a national system, can more easily land on the moon, which was the time when the former Soviet Union landed on the moon in 1960 and China landed on the moon in 1981.

In fact, in 1991, the former Soviet Union, which spent too much money on the space race, collapsed, and Da Mao and Ermao did not have a moon landing plan for the time being, and after sending its first astronaut in 2003, China decided to spend 30 to 50 years playing manned landing on the moon -- a period when China had replaced the United States as the world's factory. Although the level of scientific research at some of the top levels is not as good as that of the United States, it definitely surpasses the level of aerospace of the Americans 50 years ago -- just a small computer was unbelievable in the fifties and sixties.

According to Lin Haiyang's view, it is now 1870, and according to the speed of the United States, whether it is the launch of the first satellite or manned space flight this year, there will be no problem in landing on the moon in 1880 ten years later -- as long as the carrier rocket that surpasses the Saturn V can be designed, the industrial ship can be built, and it is not much difficult.

In another ten years, about 1890, astronauts will be sent to Mars to take a look, and it is really not advisable to stop the development of aerospace as the Americans did. It is necessary to go forward step by step firmly, which is the correct path for the development of aerospace.

The total amount of resources on the earth is limited, and even if it is a recyclable resource, once it is exploited in a predatory and destructive way, it is no longer a recyclable resource. If new colonies are not opened up in advance, future generations will inevitably embark on the road of suffering and poverty.

Only by going to space and embarking on the path of colonization and plundering of other planets can humanity avoid wars for the limited resources of the planet.

Of course, Elsa doesn't understand such a deep truth, but she can still understand sending someone to the sky or sending an artificial moon to the sky, although she doesn't quite understand what the earth's orbit and other professional terms are. It just made Elsa feel that she and these people were no longer on the same level in thought. Everyone is the same human being, why is the gap so big.

In fact, the launch vehicle is not as high-end as Elsa thinks, and in the 21st century, North Korea is still using solid fuel to put satellites. Fire. Medicine as propellant to build a super-large three-kick can also play manned spaceflight or put satellites, provided that you can figure out how to get this three-kicker into Earth orbit, and how big each layer of this three-kicker should be.

At this time, Elsa remembered Song Haiping's words, now that the rise of the Chinese nation is unstoppable, Israel can now make a lot of money to join.

As for if someone accuses Song Haiping and Lin Haiyang, now the Chinese Federation is ready to release satellites, but there are still many people in the Chinese Federation who are still eating grass. Then Song Haiping and Lin Haiyang will definitely say: "We have already given them a chance, and now they go to the United States, go to Nanyang (Australia), go to Europe, and even rob abroad with the Eight Banners, which one can't eat meat." Who is to blame for their own unwillingness to change and their willingness to eat grass. ”

Even in Japan, which was the first to carry out reforms, there are still many mountain people who are reluctant to go down the mountains, although the government has generously exempted these mountain villages from all taxes, but there is no land in the mountains, and poverty is almost a helpless thing. But in this way, there are also people who are willing to guard the old houses in the mountains and the terraced slopes in the mountains handed down by their ancestors and are unwilling to go down the mountain. Social change is a terrible and terrible thing for them, and they would rather live in the same life for the rest of their lives than try to change, which is out of fear of the unknown and the sadness of ignorance.

For such people who are afraid of change and willing to suffer poverty, Song Haiping and Lin Haiyang only hope that in a few decades, they will be able to develop these primitive villages by engaging in eco-tourism -- today's Japanese have just eaten a few years and are full, and if you let them go to the village to suffer twice, they will definitely scold their mothers. A new generation of children growing up in the city may enjoy the natural scenery of the mountain village and the poor natural food they have never seen.
