In the courtyard, under the shed, the telescope like a giant cannon immediately attracted the attention of young people.

There are paper and pen on the workbench next to the telescope, and there are many drafts on the table.

Gries didn't care about the young man's curious eyes, so he walked over and took a picture, signaling him to sit down and write his own problem-solving process.

The young man looked at the three-meter-high astronomical telescope next to him and was slightly stunning.

However, at Glace's reminder, he quickly came back to his senses, looked at him awkwardly, and sat down quickly.

Holding paper and pen and brewing for a few seconds, the young man buried his head and began to concentrate on describing his ideas in words and graphics.

After waiting for about ten minutes, Gress, the young man who had written four pieces of paper, put down his pen and rubbed his sore wrists.

Martin, who appeared at some point, stood behind the young man, looked at the words on the paper, had a smile on his face, and nodded slightly.

Although the description process is mixed with a lot of irregular terms, the overall idea is OK.

The final result is also correct.

This seems to be a very complicated problem-solving process, and the idea of ​​sequences is also used.

Moreover, the first half of Martin's derivation process is basically the same as him.

Gress didn't have time to pay attention to the young man on the table, but looked at the paper in his hand intently.

That's the answer Martin just gave him.

【1/4π=1+1/3-1/5+1/7…The process is as follows…】

Looking at this simple result, Gress was a little intoxicated.

Martin remembers that many mathematicians deduced expressions of pi in the Middle Ages on Earth.

Newton, Euler, Leibniz, etc.

This concise expression seems to be derived by Leibniz.

"May I have your name?"

Seeing the young man put down his pen after writing, Martin asked.

The young man was startled by Martin who suddenly appeared behind him, but he still stood up respectfully and replied: "Sir, my name is Farrell."

"Where did you learn math?" Martin asked again.

"Uh... I'm just thinking about it all." Farrell hesitated for a moment, and then gave this answer.

Martin raised his brow and looked at him in surprise.

Self-taught!

Such a talent is really rare.

If you train it, it should be no problem to be a teacher.

"Very good, are you interested in joining us?" Martin invited with a smile.

"Wasn't that... there is a reward?" Farrell asked embarrassedly.

He is very difficult at the moment and urgently needs this reward to completely improve his life.

Besides, he came for the bonus.

"Don't worry, the reward will not be reduced." Martin said confidently.

A few minutes later, Farrell, who received the gold coins, was very happy to sign a labor contract.

The reward and his previous job were simply from heaven and from earth to earth, which he never dreamed of.

"So, Mr. Martin, what do I need to do?"

Farrell also saw from the conversation that Martin, who was younger than him, was the one in charge.

"Grace, give him a math textbook. It's not what you learned, but the introductory textbook I specially wrote." Martin instructed.

Gries nodded quickly and pulled out a book slightly thicker than a magazine from the table.

"Your first priority is to learn mathematics. This is an introductory textbook. You must learn it within a week. There will be an exam in a week. If you fail, it may affect your salary!"

Farrell took the textbook in a daze, but when he heard Martin's last words, his heart immediately raised, and then nodded heavily, saying that he would definitely study hard and pass the assessment.

After Farrell left with his teaching materials and gold coins, Martin took out another document.

This is a drawing.

Very important drawings!

Glace looked nervous, too.

After class two days ago, Martin asked him something.

About the steam engine of Coretta.

A long time ago, Martin saw news about the steam engine in the newspaper.

From Gressna, Martin learned that the steam engine was the work of a bishop of the Temple of Craftsmen of Coretta.

The drawings in Martin's hand are also a steam mechanism that he restored based on memory.

“Is there any problem?”

More than ten minutes later, after Gress finished reading the drawings carefully, Martin asked.

Gress suppressed her excitement, calmed down and thought for a while before saying, "It's not difficult to make, as long as there is enough iron. But can it really generate such a large thrust?"

Glace was excited and couldn't help but feel a little confused.

Although he trusts Teacher Martin very much, the motivation marked on this drawing really makes him feel a little exaggerated.

Martin is actually not sure.

Because the steam engine in his memory burned coal, and he had never heard of coal mines around Faralin.

So you can only settle for the second best to burn wood.

However, the efficiency of wood is relatively low, so this steam engine should still need to be improved to maximize the combustion rate and heating rate.

In the specific situation, we still need to make the test samples and continuously debug them, so that the best solution can be obtained in the end.

"Its principle is not complicated. You can do it first and then slowly improve it according to the problem." Martin reminded.

Gress nodded deeply with consent, and then said excitedly: "Then I'll prepare some materials. If nothing unexpected happens, I should be able to make it tomorrow."

This machine cannot be too small to provide sufficient power.

So there are a lot of steel materials needed.

Making is the easiest step.

After all, after the advancement, Gladys made these things more handy.

Besides, Martin didn't think his drawings could directly create steam engines that could be put into production.

This is just a prototype.

A lot of experiments and exploration are also needed to transform it step by step into the driving force of the industrial revolution.

The steam engines in history have also gone through decades of development and evolution before they can be put into practical use.

It was a story a hundred years later when the steam engine was brought onto the means of transportation.

Fuel and efficiency are the biggest problems of steam engines.

Martin originally wanted to build a drawing of a steam locomotive through the temple, but after consulting the Count, he gave up this idea.

The Count told him that the inventions of craftsmen are personal secrets, and most of them will not be willing to share them with outsiders.

Therefore, his steam engine production plan can only depend on himself.

In addition, we have to try to find coal mines that can be developed around Faralin.

It is impossible to burn wood all the time.

Martin feels that time is not enough now.

In addition to fixed class hours and occasional case investigations, he often writes textbooks and explores mystical knowledge.

Although the main work of the steam engine research and development has been handed over to Gress, many times it still needs Martin's guidance to avoid detours.

In addition, there is municipal reform.

The Count basically talks to Martin to discuss some details every week, and many questions need to be carefully considered before answering them.

He has become a consultant in this regard.

No salary.

As soon as things get a lot, it's a bit overwhelming.

However, since reform is needed, these are essential steps.

The road still has to be walked step by step!

I read some novels in my previous life, but I only felt that everything was so relaxed and freehand, but after actually experiencing it, I realized how many difficulties there were.
