Chapter 565

Seeing the students excited and eager to boast in front of others, Zhang Yuan quickly changed a topic: "well, students, although this secret is not a top secret, it should be kept as much as possible. It's not appropriate to make it known. "

"We have a strategic partnership with the TOS civilization. If things go well, curvature spacecraft from the interstellar trading market will take us away in the future."

"But if those ships don't arrive on time, we have to rent large ships of the TOS civilization. After all, they have six motherships. In order to save time, we don't have to build one ourselves... In this way, the two civilizations have to exchange a series of benefits."

If a civilization wants to develop for a long time, it must consider all the big and small things.

The final stage of the whole neutron star collision plan needs the help of the power of the interstellar trading market, but it can not completely rely on the trading place

If the trading market breaks the contract, the whole plan will have to be carried out.

The Planetary Fortress, which already has basic power, is currently moving at a distance of about 1.6 astronomical units from the two neutron stars, and its orbit is similar to an ellipse.

The planetary engine above is only 20% turned on, and engineers have made a final safety inspection.

Talking about this topic, all the students were even more excited. They had not been in contact with the so-called interstellar trading market. They looked forward to it and doubted it.

Zhang Yuan looked at the students below and said, "if the spacecraft from the interstellar trading market arrive on time, these planetary engines will start on time, cut into the three body movement, and everyone will flee this star field. This is certainly the best solution. "

"As for the worse scheme..."

"There is no cosmic string in this star field. If it is propelled by an ion engine, it will take 300 years of navigation, which will undoubtedly affect the best observation time. Our probability of obtaining curvature technology will be several percentage points lower. "

Seeing that the class time was almost up, Zhang Yuan said, "well, that's all for today's course. Let's finish class, sort out what we have learned, and be interested in taking a look at the literature in this regard. Although the development in recent years is not too great, the next promotion work depends on ourselves."

"Class is over."

"Goodbye, teacher!"

Several students turned around and waved to him.

Zhang Yuan sorted out the documents in his briefcase and was relieved to see that all the students had left the classroom.

It's the first time to be a professor or something. Sometimes I feel very stressed.

This course is very difficult. These students are carefully selected, and their education is at least master's level... However, compared with the extra perceived difficulty, a large number of people will be eliminated.

In Deep Space University, he not only teaches masters and doctors, but also is responsible for undergraduate content, mainly mathematics and new civilization history.

Teachers teach not only knowledge, but also the exporter of values.

Now children's primary and secondary education is completed by robots. Generally, there will be no big problems. The whole process of classified education has been quite mature, and robot teachers can complete this work.

However, college is different.

University is an important link from school to society. Students will get higher freedom after graduating from high school. How to adapt to this higher freedom is an important issue. For example, in the past earth civilization, many excellent students degenerated in college. They did well in high school, but the University couldn't keep up; There are also some students who rise again in the University, that is, their subjective initiative has played a great role.

In addition, with the increasing difficulty of learning, the allocation of social work and other important tasks, university teachers are still human teachers.

Well, this kind of human teachers, of course, the better their moral character is, and the higher their role model is, the better.

Even the requirements for moral character are greater than academic requirements.

If the teacher's ass is crooked, the more knowledge, the more reactionary. Of course, the group of students taught will become social trouble.

Zhang Yuan doesn't have much task now. In addition to teaching, communicating and discussing cooperation projects with TOS people, he will work hard to learn new knowledge in his spare time, which is also very pleasant.

"... the real research task has not really started yet! Hey, I don't know if the spacecraft in the trading market can arrive in time. "

Zhang Yuan stretched out, came to the "big bucket canteen" and ordered a "golden spicy chicken roast Rice Burger".

The large screen in front is broadcasting the development of the whole civilization in recent years.

In the past 1400 years of new human civilization, the vast majority of resources have been inclined to the construction of planetary engines. There are not many resources and population for scientific and technological innovation, but the progress in science is not nothing.

The experience accumulated from long-term practice has made a great qualitative change in the field of human engineering. Many spacecraft have been upgraded, including transportation spacecraft with large carrying capacity, more powerful engines, etc. these experiences are not useless.

It can be seen from TV that countless spaceships come and go above a wooden planet to collect a large amount of nuclear fuel.

The purpose of collecting nuclear fuel is to manufacture various Super equivalent hydrogen bombs.

There are also various military spaceships with powerful mobility. These spaceships were made in large quantities when the relationship with TOS civilization deteriorated

Even if the curvature technology is not obtained in this activity, the performance of these spacecraft can be called the peak of three-level civilization!

Of course, there is a big gap between class III civilization and class IV civilization.

If the spaceship of class IV civilization is compared to a "supersonic stealth aircraft", the spaceship of class III civilization is only a propeller aircraft during World War II. The spaceship of the second civilization is equivalent to a wooden plane that can barely fly.

Level 4 civilization and level 3 civilization are hanging attacks, or even direct zero loss.

However, although the third civilization and the second civilization are also sling attacks, they do not necessarily achieve zero loss.

This is also the main reason why some four level civilizations are unwilling to popularize curvature technology in large numbers. They even concluded some treaties in the trading market.

Curvature technology has brought too much improvement in military strength and mobility.

If humans acquire curvature technology and are promoted to level IV civilization, they may also sign a leap in this regard.

As for the rest of the trades and professions, although there has been no significant qualitative change, they have also developed. Each industry has expanded a little achievements, and the science and technology tree has naturally grown many buds. Just waiting for an opportunity can quickly flourish.

"This period of time is not deserted, but it's ok... Up to now, it should make slow progress. Where can we make great strides forward?"

On the whole, Zhang Yuan felt quite satisfied after browsing the scientific and technological achievements roughly.

"Hey, Lao Zhang, where's dinner!"

Thinking like this, a capable man's voice came to my ears. It was engineer Ye Kaifu, who was the first pioneer to leave the earth like Zhang Yuan.

When Zhang Yuan was still the captain of the Kunlun Mountain fleet, ye Kaifu was his capable general, specializing in mining and other logistical work.

Of course, this kind of talent who specializes in mining has been forced out.

Seeing this guy, Zhang Yuan also smiled happily, "it's rare. Is today your holiday? I'll treat you to Golden Chicken and rice! "

They chatted casually while eating.

Perhaps because of the influence of the times, among the 500000 pioneers who left the earth at the beginning, the proportion of becoming extraordinary is faster and higher than those in the rest of the years.

Suffering can really promote people's growth.

Zhang Yuan felt that the proportion of middle-aged and elderly people in this era who did not leave with the last spaceship should also be very high.

In other times, it will be relatively lower.
