Joseph looked excited and greeted them one by one. However, when facing Laplace, he couldn't help but quietly clench his fist and beat him in his heart - this is also a wish that later generations of science and engineering students will make when they are faced with the problems on the test papers, helplessly looking out of the window, but just seeing a meteor flying from there.

Joseph didn't have a chance to beat Laplace back then, but now this damn guy is actually standing in front of him, but Joseph still can't beat him, so he can only greet him with great enthusiasm and say: "Mr. Laplace, I have read some of your writings, and those things have inspired me a lot. What a blessing to meet you! As he spoke, he stretched out both hands and held his hand, just like the president of *** held Macron's hand, first squeezed it hard, and then pulled the other party's hand to his side, causing Laplace to stumble and almost fall.

"Mr. Laplace, it's such an honor to meet you, I have a lot of questions for you, such as ......" Joseph said as he gritted his back molars with a smile on his face, and with all his strength, he squeezed Laplace's hand with both hands.

"Ah...... Mr. Bonaparte...... Mr. Bonaparte...... You're really ...... Or sit down first, and then ...... Slowly ...... Talk slowly......" Laplace's right shoulder rose high, and he stumbled as he tried to pull his hand back.

"Ah, Monsieur Bonaparte, let us sit down and talk. You're so enthusiastic, you may have hurt Pierre's hand. Seeing Joseph so enthusiastic, and Laplace being held by his hand, his face was a little distorted in pain, Lavoisier couldn't help but want to laugh, but he stopped Joseph anyway.

"Huh?" Joseph made a look of surprise, quickly let go of Laplace's hand like an electric shock, and kept apologizing: "Mr. Laplace, I'm really sorry, I'm really sorry, I'm so excited to see you...... That's really ...... You're not hurt......"

Laplace moved his right hand for a moment, and then said, "Monsieur Bonaparte, how can you have so much strength?" ”

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

"That's not a little bigger." "But we're not going to talk about it now — you know, we saw your paper, and both Mr. Lavoisier and Mr. Condorcet admired it, but you know that your paper is trying to overturn a theory that is universally supported and supported by a lot of experimental phenomena, and that's a big deal, and everybody thinks it's better to be cautious, so Mr. Lavoisier and Mr. Condorcet, and some other gentlemen, would like to talk to you face to face about this paper......"

"Honestly," said Condorcet, smiling mildly at Joseph, "Monsieur Bonaparte, this paper of yours is one of the few high-level papers of all these years, and if nothing else, the few mathematical tools in the paper alone will be enough to win you the competition." However, some people disagree with your conclusion. Well, at least neither Cullen nor Monge liked your conclusion. They're on their way over, and maybe they'll have a whole bunch of questions for you. You have to be mentally prepared. ”

"Monsieur Condorcet, you can just call me Joseph." "I thought about this before I wrote this. To be honest, when I came to this conclusion, I was also worried that I was mistaken. And I wrote this paper precisely so that I could discuss this issue with others. ”

"Haha, young people are really good now." Lavoisier said, "Joseph, you mean you're ready?" Well, you don't have to be nervous, actually, ......"

He was only halfway through his sentence when he heard the door of the small living room being pushed open.

When Joseph saw a few more men coming in, he quickly stood up.

The others followed suit. Leading the way was His Royal Highness Louis-Philippe Joseph of Orleans, whom Joseph had met once in the café. He was followed by two men in military uniforms, one of whom was older and looked to be in his fifties; The other was slightly shorter, with a bronzed face, a pair of bushy eyebrows, and a pair of piercing eyes.

"Your Royal Highness, why are you here too?" Condorcete Road.

"Ah, Monsieur Condorcet, I was passing by here to-day, and I had come to visit Monge, and when I heard him talk about the things here, I found that the man who had caused the controversy, Mr. Bonaparte, seemed to be a little friend of mine who was like Joseph, and came to have a look. Outcome...... Joseph, it's really you. As he spoke, Duke Charles came over, stretched out his hand, and took Joseph's hand. Laplace's eyes widened, staring at their hands, however......

"Ah, Joseph, the last time I met you, I thought we would have another playwright in France, but I didn't expect there to be another mathematician. However, Monge does not seem to agree with some of your views. I'd like to discuss it with you, but of course, I don't understand any of these things. I'm just here to see the fun. The Duke of Orleans let go of Joseph's hand and said, "By the way, Joseph, I have come to introduce you to these two friends of mine." ”

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

Joseph hurried forward and greeted Cullen and Monge. Duke Charles found a chair for himself and sat down, saying, "You know, I don't know much about science, but I'm very interested. Monge, you have a lot of questions to ask Joseph, and now you can begin. ”

Monge was a simple man, and when he heard this, he immediately spoke: "Mr. Bonaparte, you have identified light as a transverse wave in your paper, and your mathematical derivation is impressive, but you should know that both Ren and wave propagate in a medium, and if light is really a wave, then what characteristics of this medium, this light ether, need to have, have you thought about it?" ”

Joseph had been prepared for this question for a long time, because in the historical development of later generations, various doubts about the "light ether" were the main weapons used by the proponents of particle theory to oppose the wave theory.

"That's how I think about it...... Joseph began.

Joseph knew that the so-called "light ether" was abandoned by scientists in later generations. But at this point, he can't directly say that the aether doesn't exist, because it requires a lot of scientific discoveries and scientific experiments as a prerequisite. So he could only deal with the problem of Monge with some of the conjectures of the proponents of the fluctuation theory before that.

"On the question of the hardness of the ether, and also about what the speed of light is, I envisioned an experiment that could be used to measure the speed of light more precisely. Considering that the earth is constantly moving, 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 came interested.

"We use an eight-sided ......mirror that can be rotated," Joseph said. The method he is talking about is the Michael Ersun Rotating Prism Method. It is a relatively simple means of measuring with good accuracy.

While presenting the experimental concept, Joseph took a piece of paper and a pen in his hand and began to draw a design of the equipment needed for the experiment.

Josephus habitually depicted these devices in the same way that was common in later generations to draw three-sided projections. But as soon as he saw the pictures he had drawn, Monge's eyes widened suddenly.

"Monsieur Bonaparte, where did you learn this way of drawing?" Monge asked.

"Huh?" Joseph was taken aback, he originally thought that this kind of drawing method should be a very common technique, but when he heard Monge's question, and saw the expression on Monge's face was extremely serious, he immediately realized that perhaps, in this era, this kind of drawing method did not appear at all.

"I did it myself, and I think it's more intuitive and easy to understand. What, is there a problem here? Joseph said.

Monge thought for a moment, and replied, "Monge, you may, no, you certainly don't know, that I began to use a similar drawing method almost twenty years ago. But because this drawing method is of great military significance, I think, with your cleverness, it is not difficult to understand this, so this drawing method is kept strictly secret. It may only be taught in military academies, and all officers who have learned it must take an oath that this skill must not be passed on. As I said back then, it might not be long before someone else would independently study a similar technique, just as Newton and Leibniz invented calculus. However, since your drawing method is so similar to the secret drawing method, I am afraid that this work of yours needs to be kept secret as well. Monsieur Bonaparte, you didn't teach this method of drawing to anyone else, did you? ”

"I only taught this technique to my brother Napoleon, who is now in the first year at the École des Officers in Paris. Well, he's pretty good at math too. ”

"In the first grade, the first grade has not been exposed to drawing geometry." "Monsieur Bonaparte, remind him that this technique cannot be passed on. ”

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

"Duke, that's not what I meant, it's a decision of the Royal Government. I can only obey. Monge replied. He turned to Joseph again and said, "Monsieur Bonaparte, this discovery should have brought you honor and status, but now you must hide it. For the sake of France, this is a necessary sacrifice and I hope you can understand. ”

Joseph nodded and said, "I understand that although science has no borders, scientists have nationality. ”

"Just like Leibniz's calculus and Newton's calculus, there are still a lot of differences. Mr. Bonaparte, I think there are some differences between your way of painting and that of Monge. Cullen suddenly said, "Can you tell us about your drawing?" ”
