If Louis was to some extent handsome, almost like Prince Paris who handed over the golden apple to Aphrodite, walked out of the myth, or like an archangel who sounded the horn of the judgment of the end of the day, landed in the clouds with flames and thunder; the next friend Arman introduced to Joseph was almost the same as another extreme in appearance.

This is a thin short man. He has a waxy face, two eyes, one small, and a big nose, but very flat, just like someone slapped it hard, so he slapped it flat. His forehead was also flat, his jaw was very thick, and protruded outward. This made his mouth look particularly big, and when he looked over, he looked like a toad. In addition, he was thin, but his finger joints were somewhat prominent, and his black and yellow skin looked particularly dry due to skin diseases, and it looked like a monster that slipped out of a nightmare.

"Joseph, this is my friend Mr. Mara."

"I'm glad to see you." Joseph nodded and stretched out his hand.

Mara also stretched out his hand and held Joseph's hand. However, he held it very shallowly, and almost just gently pinched Joseph's fingers with the tip of his fingers. Joseph found that Mara's hand was quite cold.

"Mr. Bonaparte, I've read your paper. Do you think light is a wave?" Mara said slowly, his voice was equally cold.

"This is not what I think, but the existing evidence makes me more inclined to this judgment. I have no prejudice about whether light is a particle or a wave," Joseph replied.

"Why don't you dare to support your point of view clearly and use such a weak statement to cover up your position? Is this because you don't have confidence in your judgment?" Mara said in a sarcastic tone.

Joseph couldn't help frowning, and a sentence suddenly popped up in his heart: "Emperor people make trouble!"

Indeed, "ugly people make a lot of trouble." Generally speaking, people with too low appearance are easily discriminated against in society. These discriminations often make their hearts full of anger and make them full of aggression. In Joseph's view, Mara is a typical example.

However, Joseph didn't want to offend Mara at this time, because it was too dangerous to offend this guy. Although Joseph was not very clear about the history of the Great Revolution (after all, this was foreign history before traveling through time, wasn't it? To be honest, knowing Mara's name also means that he didn't doze off when he was in history and art classes). But he also knew that Mara might be responsible for many horrifying atrocities in the Great Revolution. There are probably no fewer people who have revenge in this, and Joseph was unwilling to get into such a mad dog.

"Anyway, this guy won't live long, let him go first." Joseph suppressed his retorted plan and said to himself.

"I really have no prejudice about whether light is a wave or a particle. As for my point of view, my point of view is that what it is depends on experimental phenomena and mathematical explanations. If I can explain interference phenomena from the perspective of particles in mathematical ways, I will be very happy. After all, the world is so complicated, and only mathematics can be truly trusted." Joseph explained.

"Ah, Joseph, your point of view is a bit like Pythagoras." Dandong smiled and said, "Is everything counted?"

Pythagoras was a famous mathematician in ancient Greece. He and his disciples formed an important school of Pythagoras. One of the basic concepts of this school is "everything is counted". They believe that mathematics is the only thing that can be used to describe the entire world and is also the true essence of the world.

"I'm not as fanatical as them." Joseph smiled slightly, "At least, I wouldn't throw someone into the sea just because he discovered an unreasonable number. But, my friend, you think about it too. Is our vision reliable? That's not necessarily. For example, I found that some people see different colors than others. I think..."

"Wait...what did you say just now? You said that some people see different colors than others? Are you sure there is such a person?" Mara suddenly interrupted him.

"Yes, what's wrong?" Joseph asked.

"It may be a new disease that people have not noticed before," Mara said. "Can you tell me how you discovered it?"

"When I was a child, a friend suddenly came to tell me one day that he found that the geranium flowers in my house would appear in different colors during the day and in the evening. The geranium flowers during the day were sky blue, but the geranium flowers in the evening were bright red. However, in my opinion, at any time, those geranium flowers were pink. When I told him this, he was very surprised and even suspected that there was something wrong with my eyes. So we asked a few more people, and in the end, everyone agreed that the geranium flowers should be pink. Later we found that his uncle also thought that the geranium flowers were blue during the day and bright red in the evening. But I was still envious of them at that time because they could see two colors of geranium flowers."

"Can your friend come and let me see?" Mara asked again.

"He is from Corsican, and he is in Corsican, and he can't find him now." Joseph spread his hands.

"Ah..." Mara curled her lips harshly, "Mr. Bonaparte, do you know that I have a friend who is amazingly bouncing and can jump directly to the moon."

Joseph quickly said to himself several words in his heart, "Don't be as knowledgeable as this guy", which suppressed the urge to retort directly. But at this time, Dandong said:

"Is it possible that the color of the zodiac flowers has not changed during the day and in the evening? Is it just that I misread it? Is there something wrong with my vision?"

So everyone turned their attention to Dandong together.

"Why are you staring at me like this?" Dan Dong said.

"Dandong, in your eyes, will the color of the Tianzhu flowers change during the day and evening?" Mala asked, staring at Dandong with the same eyes as she admires and cherishes animals.

"Yes...what you saw isn't like this?" Dandong asked back.

"Look at what color this is?" Mara asked suddenly pointing to Louis's hair.

"Linse color, shouldn't it?" Dandong was a little unsure.

"Well, that's right, no problem... Well, what color is Aman's hat?" Mara asked again.

"It's green." Dandong replied immediately.

"Look at it again?" Mara said.

Dandong opened his eyes wide, stared at Aman's hat for a while, and then said, "It's green."

"God! The color you see in someone's eyes is different from others! Armand's hat is obviously light red!" Mara clapped his hands, and then he turned his head to Joseph and said, "Mr. Bonaparte, look at how dull you are. Don't you know that this is a major medical discovery?"

"I'm not a doctor after all," Joseph smiled. "I'm almost entirely illiterate in medicine."

"Don't you plan to study this issue seriously?" asked Mara.

"No, this is not a field that I am familiar with and interested in. There are still many mathematical problems to be studied." Joseph replied, "Let's go back to the topic at the beginning. I think our vision is unreliable, and our hearing is the same. Some people claim that they can hear some voices that others cannot hear..."

"That's just a trick for the charlatans to deceive people." Mara interrupted.

"Ordinary people also have this kind of times," said Joseph. "For example, when dreaming, we can hear many sounds that do not exist, and see many things that do not exist at all. Our vision will deceive us, our hearing will deceive us, and even our imagination can deceive us, such as 0.9999... is equal to one. But mathematics cannot. Well, I remember a priest who said: "When the sky turns over, the cross stands." I don't comment on whether the cross can stand, but I am sure that even if the entire solar system is over, I am sure that two points can still determine a straight line. So, when other things are unreliable, the only thing I can trust is mathematics. Since mathematical calculations show that light is likely to be a wave, I admit this possibility."

"What if your mathematical calculations show that light is often like particles?" Mara asked again.

"Then it could be a particle," Joseph replied.

"The hopeless believer of Pythagoras." Mara shook her head, "Mr. Bonaparte, truth is not only presented through mathematics, it has other, higher ways of presenting it."

"What's the way?" Joseph asked.

"From the intuition of the soul," Mara replied, "Have you read "On the Soul of Man" and "Philosophical Papers on Humanity"? I think some of the views here make sense. For example, the colors seen by different people in their eyes must be related to their souls..."

"On the Soul of Man" and "Philosophical Papers on Man"" Lavoisier mentioned these two things when talking about Mara:

"That Mara, in his nonsense paper, also quoted two nonsense articles, such as the nonsense rumor in "On the Souls of Man" and "On the Philosophical Papers on Humanity". With that chaotic way of thinking, I am sure that the two anonymous things were written by him."

Now it seems that Lavoisier's guess should be very reliable.

"I really didn't expect that in this era, I could meet Minke." Joseph couldn't help but sigh in his heart.
