Joseph showed an excited expression and greeted them all. But in the face of Laplace, he could not help but quietly clench his fist, and in his heartbeat he up - this is also the latter-day students of science and technology in the face of the difficult questions on the paper, helplessly looking out the window, but also happened to see a meteor flying through the time, a wish will be made in a hurry.

Joseph did not have the opportunity to beat Laplace, and now this damned guy actually stood in front of his eyes, but Joseph still can not beat him, can only welcome him with great enthusiasm: "Mr. Laplace, I have read some of your writings, those things have given me a lot of inspiration. I'm so lucky to meet you! He said, "I'm so lucky to have met you." While saying that, he put both hands out and took his hand, just as President **** had taken Macron's hand, first squeezing it hard and then pulling it violently toward him, causing Laplace to stagger and almost fall.

"Mr. Laplace, it is a great honor to meet you, I have many questions to ask you, such as ．．．．．．" Joseph said this with a smile on his face, gritting his back teeth while using all his strength to squeeze Laplace's hand with both hands.

"Ah ．．．．．． Mr. Bonaparte ．．．．．． Mr. Bonaparte ．．．．．． You are really ．．．．．． Or sit down first, then ．．．．．． And then slowly ．．．．．． Take your time and talk ．．．．．．" Laplace's right shoulder was raised high, and he said intermittently as he struggled to pull his hand back.

"The first thing you should do is to sit down and talk. You are so enthusiastic that you may have hurt Pierre's hand. Seeing Joseph's enthusiasm, and Laplace's face distorted by the pain of his hand, Lavoisier felt like laughing, but he called out to Joseph.

"Ah?" Joseph made a shocked look, and quickly released Laplace's hand, and kept apologizing: "Mr. Laplace, I'm sorry, I'm sorry, I'm too excited to see you ．．．．．． This is really ．．．．．． You're not hurt, are you? ．．．．．．"

Laplace moved his right hand a little and said, "Mr. Bonaparte, how did you get so much power?

"Pain and hatred give me strength." Joseph thought, but said, "I often help Father Jean-Jacques with his carpentry work, so I may have a little more strength in my hands.

"That's not a little bit stronger," Laplace said. Laplace said, "But we're not going to talk about that now you know, we saw your paper, and Mr. Lavoisier and Mr. Condorcet both appreciated it, but you know your paper tries to disprove a theory that has general support and is supported by a lot of experimental phenomena, and that's a big thing. So Mr. Lavoisier and Mr. Condorcet, along with some other gentlemen, would like to talk to you face to face about this paper. ．．．．．．"

"To be honest," said Condorcet, smiling gently at Joseph, "your paper, Mr. Bonaparte, is one of the few papers of a high standard in these years. However, some people do not agree with your conclusion. Well, at least Cullen and Monge don't like your conclusion. They're on their way over here, and maybe they'll have a bunch of questions for you. Be prepared."

"Mr. Condorcet, you can call me Joseph," Joseph said. I thought about this before I wrote this article," Joseph said. To be honest, when I came to this conclusion, I was worried that I had gotten it wrong. And I wrote this paper so I could discuss it with others.

"Ha, ha, ha. It's nice to be young these days," Lavoisier said. Joseph, you mean you're ready for this? Well, you don't have to be nervous．．．．．．"

The door of the small living room was pushed open.

Joseph saw a few more people come in, so he hurriedly stood up.

The others also stood up with them. The one who led the way in was His Royal Highness Louis-Philippe Joseph of Orleans, whom Joseph had met once before in the café. He was followed by two men in military uniform, one older, about fifty years old, the other slightly shorter, with a bronzed face, and a pair of thick eyebrows and gleaming eyes.

"Your Highness, what brings you here?" Condorcet said.

"I came to visit Monge and heard him talk about this place, and I found that the Bonaparte who started the controversy seemed to be a child named Joseph whom I know, so I came to see him. The result is ．．．．．． Joseph, it's you. The Duke of Charlie said, while walking over, reached out his hand, and took Joseph's hand. Laplace stared at their hands with wide eyes, but ．．．．．．

"The last time I met you, I thought we had another playwright in France, but I didn't think we had a mathematician. However, Mr. Monge seems to disagree with some of your views. I would like to discuss with you, of course, I do not know anything about these things. I'm just here for the fun of it. The Duke of Orléans let go of Joseph's hand and added: "By the way, Joseph, let me introduce you to these two friends of mine.

He pointed to the older one and said, "This is Mr. Cullen, he is an electricity authority. Then he pointed to the shorter, younger one and said, "This is Mr. Monge, he is an authority in geometry.

Joseph rushed forward and greeted Cullen and Monge. Duke Charles found himself a chair and sat down: "As you know, I don't know much about science, but I'm very interested. Monge, you have a lot of questions to ask Joseph, now you can start.

Monge was a crisp person, and when he heard this, he immediately opened his mouth and said, "Mr. Bonaparte, you have identified light as a transverse wave in your paper, and your mathematical derivation is impressive, but you should know that any and waves are propagated in a medium, and if the light is a wave, what are the characteristics that this medium, this light ether, needs to have, have you thought about it?

Joseph was prepared for this question because, in later history, the various doubts about the "light-ether" were the main weapons used by the proponents of particle theory to oppose the fluctuation theory.

"Here's what I think about this issue ．．．．．．" Joseph opened his mouth.

Joseph knew that the so-called "light-ether" had been abandoned by scientists in later times. But at this time, he could not directly say that the Ether does not exist, because it requires a very large number of scientific discoveries and scientific experiments to do the front foundation. So he could only put some conjectures of the proponents of fluctuation to cope with the problem of Monge.

"The question of the hardness of the Ether also involves the speed of light, and I have designed an experiment that can be used to measure the speed of light more precisely. Considering that the Earth is in constant motion, it should also be in constant motion relative to the Ether, so the speed of light measured from different directions may be different ．．．．．．"

"A more accurate way to measure the speed of light?" Condorcet became interested.

"We use an eight-sided mirror that rotates ．．．．．．" Joseph said. The method he was referring to was the Michaelson rotating prism method. It is a relatively simple and accurate means of measurement.

Joseph introduced the experimental design while handing over a piece of paper and a pen, and began to draw the experimental equipment required for the design of the diagram.

Joseph habitually used the way of drawing three-sided projections to depict the equipment, which is common in the later world. But when he saw the drawings, Monge's eyes widened.

"Mr. Bonaparte, where did you learn to draw in this way? Monge asked.

"Ah?" Joseph was taken aback. He had thought that this kind of drawing should be an uncommon skill, but when he heard Monge's question and saw the extraordinarily serious expression on Monge's face, he immediately realized that perhaps this kind of drawing did not exist in this era.

"I think this is a more intuitive and easy-to-understand drawing. What, is there a problem here? Joseph said.

Monge thought about it and replied, "Mr. Bonaparte, you probably, no, you certainly don't know that I started to use a similar drawing method almost twenty years ago. But because of the military significance of this kind of drawing - I think, with your intelligence, it is not difficult to understand this - this kind of drawing is strictly confidential. It could only be taught in military academies, and all officers who learned it had to take an oath not to pass it on. As I said above, it may not be long before someone else develops a technique similar to this independently, just as Newton and Leibniz invented differential calculus. However, since your method of painting is so similar to that of secrecy, I am afraid that this result of yours will also need to be kept secret. Mr. Bonaparte, you have not taught this method of drawing to anyone else, have you?

"I have only taught it to my brother Napoleon, who is now in his first year at the École Militaire in Paris. Well, he's also good at mathematics.

"The first grade, the first grade is not exposed to the geometry of drawing. Monge said, "Monsieur Bonaparte, you must remind him that such skills must not be passed on.

"Is there such a thing?" Duke Charles was interested, "Monge, science should belong to all mankind. It's not a good idea to keep it a secret."

"Duke, it is not my intention, it is the decision of the kingdom government. I can only obey it." Monge replied. He turned to Joseph and said, "Monsieur Bonaparte, this discovery should have brought you honor and status, but now you must keep it hidden. I hope you understand that this is a necessary sacrifice for the sake of France.

Joseph nodded: "I understand that science has no borders, but scientists have nationalities.

"Just as there is a difference between Leibniz's calculus and Newton's calculus. Mr. Bonaparte, I think there should be some differences between your painting method and Monge's painting method, too. Cullen suddenly said, "Can you tell us about your painting method?
