Joseph knew that Cullen was quite skeptical about his so-called independent research on "geometry", perhaps because the real pioneer of "geometry", Monge, was a child prodigy himself, so he was less skeptical about other child prodigies who had created similar techniques at a similar age as himself.

Joseph had indeed studied painting geometry in his previous life, and he believed that after centuries of development, the painting geometry of later generations must have evolved more than the painting geometry of this time. However, he did not know how far Monge's original geometry had developed. After thinking about it, Joseph thought that some of the techniques of projection transformation were probably developed in later times, so he recalled them carefully in his mind and then added some of them to the content and talked about them in detail.

The Duke of Orléans listened with great interest until Joseph finished one part of his speech and stopped for a while, then he asked Monge, "Mr. Monge, how does Joseph's method compare with yours?

"More or less the same," Monge said. After he finished, he looked at the group and suddenly realized that his words might have implied that Joseph had not made the geometry of the drawing himself, so he hurriedly added: "But there are still some differences, for example, the projection transformation he used in how to handle the map is very interesting, which I had not thought of before. This way the map will work better. The method that Mr. Bonaparte created is the same as mine in principle, but it is even better than mine in terms of practicality. You are a genius in mathematics, Mr. Bonaparte!

The geometry of Monge's drawings had been kept secret, so even those who were next to him had not been exposed to much of it before, and when they heard what Monge said, they naturally dispelled their doubts.

"Joseph, I didn't expect you to be a mathematical genius. Well, last time I heard you were still in high school? In ．．．．．．" Duke Charles suddenly couldn't remember which high school he was in.

"The school is Louis the Great, Your Highness. Joseph and my nephew Amand were classmates. Lavoisier added with a smile.

"That's right, that's right. I saw him with Amand last time. Duke Charles looked at Joseph with admiration, "It's a blessing for France to have such young people popping up all the time. However, it is unfair that they are not given the honor they deserve for such achievements and even live in poverty. I think we should give Joseph some compensation for this.

Condorcet nodded and said: "I think that Joseph's essay is at least very controversial and should win the prize of six hundred francs.

Because the Duke of Orléans mentioned compensation, even Cullen and Monge did not object.

"This is too little." The Duke of Charles was not satisfied.

"Don't worry, Your Highness, such talent won't be buried," said Condorcet. When this paper is published and the light speed experiment is completed, I think Joseph will be able to get a teaching position at the University of Paris or even a position here," Condorcet said. Well, Joseph, I heard that you're going to graduate soon. How about it, are you interested? I can give you a letter of recommendation."

Joseph hadn't had time to say anything, but Monge jumped in front of him and said, "Joseph is very talented in geometry, but it's a secret skill. If he goes to the University of Paris, he won't be able to study it very easily. It would be a shame. The Paris Military Academy is looking for a teacher who can teach geometry, and they have asked me to recommend an expert to them. Why don't I recommend him, together with Mr. Laplace, to teach mathematics at the Ecole Militaire de Paris? I think it would be better. And I can get him more allowances and more income than at the University of Paris. What do you think, Joseph?

In terms of prestige alone, the University of Paris is certainly more prestigious. But in terms of income, it is true that, as Monge said, teaching at the École Militaire de Paris would be more profitable. In addition, Joseph knew that the revolution is about to break out, in the revolution, the various forces you sing and I take the stage, today in the street lamp post hung with the royalists, tomorrow the guillotine on top of today's revolutionaries. And the University of Paris, is the convergence of various political schools, if you go here, you may be uncontrollably involved in the political struggle for whatever reason. In contrast, the Paris Military Academy was much safer. And after entering the military system, he could also do some necessary preparation for the future.

The narrative has been illicitly obtained; should you discover it on Amazon, report the violation.

Thinking of this, Joseph said to Monge: "Mr. Condorcet, thank you very much for your recommendation. But I think I still prefer Mr. Monge's suggestion. My father has just died, and I have several younger brothers in school, so I need money now. And my brother Napoleon happens to be at the Ecole Militaire in Paris. He is a troublemaker, and I think I can keep a better eye on him by going there.

Hearing this, everyone laughed together. Duke Charles said while laughing: "It seems that all brothers always think that the brother is a troublemaker. Well, I can imagine what it's like to be the brother who enters the classroom and finds out that the teacher above is his brother ．．．．．．"

"The first thing you need to do is get back to the light speed experiment. Lavoisier said.

"Okay, let's continue ．．．．．．"

．．．．．．

Two days after this visit, Joseph received an official letter from the French Academy of Sciences by courier, informing him that he had won a prize for his thesis and a prize of six hundred francs.

The prize money made Joseph's life a lot richer. After two more days, he received another letter from Monge. In this thick letter, Monge told Joseph that the Academy had finished preparing the experiment on the speed of light and was going to conduct it in the evening of ten days later - there was no moon that night - at a castle of the Duke of Orléans.

At the end of the letter, Monge told Joseph that he had recommended him together with Laplace. It was believed that in a few days he would receive an official letter from the Ecole Militaire in Paris. As soon as he graduated, he could report to the military academy in Paris.

Joseph was very proud to get the letter, but it was a pity that Napoleon was not around to show off to him. However, it would be better if he could suddenly appear in Napoleon's classroom in his uniform. Well, you can also point Napoleon to the blackboard to do difficult questions. This is really, think about it all makes people feel happy.

In addition, with money in his hand, Joseph immediately remembered the classic line of the "Water Margin" by Master Lu: "The mouth is faded out of Neo! Joseph calculated that if he went to the restaurant, for two francs, he could have a big meal and eat a lot of oil. But considering that Napoleon was not there, Joseph could not leave his brother and go to eat alone. So he had to continue to endure a little, but the next weekend is only a few days away. When the weekend, you can take Napoleon out to eat a big meal.

It's just unfortunate that there are several restaurants on Joseph's way to school. The restaurants were not high class, and the prices were not particularly expensive-at least, not in the eyes of Joseph, who now had several hundred francs in his pocket. In the old days, when Joseph passed by here on his way to school, he often smelled the smell of meat soup coming from these restaurants. But at that time, Joseph didn't even have a coin in his pocket, so the smell of the broth didn't seem to be particularly tempting, but at most, Joseph swallowed, held his breath, and quickened his pace. But this time, the situation was a little different. With money in his pocket and the possibility of a real meal, the aroma of the broth became more and more irresistible. Joseph tried to pick up his pace, but the broth seemed to turn into an elastic cord, binding him and pulling him backward with great effort. It took Joseph a lot of effort to break free, and when he arrived at school, he was late for class for the first time in his life. Luckily, the teacher didn't notice him because he was too nearsighted, giving him a chance to sneak into the classroom.

Thus, it was easy to get through the weekend, and generally speaking, Napoleon would walk to Joseph after school - it was less expensive. Given the walking distance, it would be about 5:00 p.m. when he arrived, just in time for a meal at the restaurant. Joseph told Father Jean-Jacques early that tonight when Napoleon arrived, they would go out together for a good meal, so that today, including Father Jean-Jacques, there would be no need to eat black bread.

However, it was not until almost seven o'clock that Napoleon came slowly to Joseph, and at this time, all the restaurants on the street were already closed - this was not a time of rich nightlife after all. Father Jean-Jacques, who was too hungry to wait, made himself half a loaf of leftover dry bread and ate it with water.

"Why are you so late? Joseph asked with displeasure.

"A man invited me to a meal," Napoleon said. Napoleon said.

"Damn it, you ate?" Joseph, who was starving, could hardly contain his anger, "Wait a minute ．．．．．． You were invited to dinner? I heard that you're not very popular at school?"

"I helped him finish his math homework. I helped him with his math homework," Napoleon said smugly.

"But I'm still hungry. ．．．．．．" Because of his hunger, Joseph was not even interested in showing off his prize money to Napoleon.

"You are waiting for me to finish eating together? Napoleon was shocked, "It's just two black bread? What's the point of waiting?

"Well, tomorrow you will eat black bread! Joseph said through clenched teeth.
