I Build an Aircraft Carrier in the Ming Dynasty

After a trip to the palace, Wu Changqing certainly wouldn't go back immediately.

He wants to stroll around Nanjing city and inspect the things he cares about.

In the university hall, he has not come to teach students for a long time.

Compared with teaching students, it is more important to deal with political affairs.

Today's Daxuetang has entered a healthy stage of development, and the top group of people are conducting various scientific researches while self-studying.

A group of people who have learned a little less are acting as teachers in the school, imparting basic knowledge to others.

Their abilities are limited and they cannot be expected to teach how well or how deeply.

Most of the time, they can only teach a little, and stuff those theories into the heads of other students.

As for whether they can understand and be inspired by it, it all depends on the student's own talent.

If you want to learn the essence, you mainly rely on self-study by talent and hard work.

Those who are talented and willing to work hard will be trained by the academy.

Ordinary teachers can't answer their questions, they can go to the top people to ask for advice, and if they are lucky, they can also be their assistants and learn by doing.

Of course, this mechanism for cultivating talents is not as efficient as schools in later generations.

However, this is the most efficient way at the moment.

Relying on this mechanism, Dahua has cultivated more than ten talents equivalent to the undergraduate level of later generations in less than two years, and there are more than two hundred talents equivalent to the high school graduation level.

There are more than a thousand at the junior high school level.

Having a high school level is actually quite remarkable. This level, coupled with the fact that the imperial court has provided funds for them to study, can already produce some results.

Coupled with Wu Changqing's direction, providing ideas and even technical support when necessary, the current research and development speed of these people is quite amazing.

At present, there are several strategic R\u0026D projects in the university hall.

The first is the steam engine project. The steam engine still needs to continuously improve its performance, requiring more power and a smaller volume.

The second is the material research project, which studies various alloys, ceramics and other basic materials.

The steam engine has been unable to achieve a major breakthrough, and the fundamental reason is the lack of suitable materials.

Ordinary steel can't withstand that kind of high temperature and high pressure, and even if a high-power steam engine is built, it won't run for long.

At this time, it is necessary to add a certain amount of other rare metals to the steel to make special steel that can withstand high temperature and high pressure.

In the original history, this process was not easy. It depended on countless people to try little by little, and after countless trial and error, some rules were ended.

The process of getting to know other rare metals alone takes an inexplicable amount of time.

Now Dahua doesn't need to work so hard to study materials. Most of the metals are listed in the textbook. They just need to search according to the textbook.

Today, more than ten metals have been discovered and confirmed by Dahua.

However, the production of other rare metals is still a big problem for the time being.

The third study of rubber application.

This is the direction Wu Changqing personally pointed out. He bought a batch of natural rubber from Western merchants, and then asked the people in the university to study how to use it.

Rubber is a very important material in human history, and can even be called a strategic material.

In transportation, rubber is used in all kinds of tires.

In industry, rubber is required for tapes, hoses, belts, etc.

In military terms, a tank needs at least 1,000 catties of rubber, and a 30,000-ton warship has 50-60 tons of rubber.

Even Dahua still can't build tanks and large warships, but rubber is used for tents, raincoats and leather shoes are excellent.

In the future, I will attack the places where it rains all the year round in Southeast Asia. Without a pair of long rubber shoes, the soldiers' legs will fester within a few days.

Not to mention the current technology, even in the 1960s and 1970s, soldiers from foreign forces who were not used to the local climate would suffer in this environment.

In such a place, a pair of dry socks and a pair of leather boots are more important than a rifle in hand.

Construction field, medical field, electrical communication...

In short, the status of rubber is irreplaceable.

"How is the research on rubber going now?"

Wu Changqing asked Fei Yufeng, the person in charge of the next project.

Fei Yufeng is also one of the top students, and his talent is comparable to Feng Xianzhong and others.

"Students are ashamed that they have not been able to solve the properties of rubber's stickiness and breakability. If these two problems cannot be solved, the rubber becomes soft when heated, and becomes brittle and hard when cold, which is not practical. "

Fei Yufeng said depressedly that several other projects are now in full swing, and the lack of progress in his project made him very anxious and anxious.

"You can try adding some sulfur to this rubber. As far as I know, there will be some kind of reaction between the sulfur in the rubber and the sulfur, and the vulcanized rubber after the reaction will become elastic, resistant to high temperature, and increase the tensile strength.

However, how much to add and how to add it is something you need to explore. "

Wu Changqing only knew that rubber needs to be vulcanized before it can be practical.

But he didn't know how to vulcanize it.

road.

Of course, he could go directly to the system mall to exchange this technology, but he didn't.

After all, Dahua's demand for rubber is not so urgent for the time being.

More importantly, Wu Changqing needs talents and needs these people to grow up by their own research and exploration.

Telling the other party directly about everything can only cultivate the other party into a skilled worker, but cannot cultivate it into a talent with research ability.

And talent is what Wu Changqing attaches the most importance to.

Without hundreds of thousands of talents to implement it, his technology is useless.

Unless he does not deal with major political affairs every day, and concentrates on scientific research.

That way, it won't be long before those powers fall into the hands of others. In the end, he may be helping others build a better society.

"Vulcanization, students try it immediately."

Fei Yufeng said.

As for Wu Changqing's words, these emperor's disciples unconditionally believe it.

Wu Changqing said that vulcanization is useful, and he decided to vulcanize rubber.

After all, Wu Changqing has created too many miracles. In their opinion, Wu Changqing is omniscient and omniscient.

Their admiration for Wu Changqing is much higher than others.

As the saying goes, the more people know, the more ignorant they feel.

Those of them who know a lot know how great the inventions and theories Wu Changqing made.
