Ruby is a physics teacher, and the whole school is doing so at a super fast pace, and the students who have only learned magic since birth are like opening the door to a new world, and Luby can solve many phenomena that cannot be explained by magic in their daily lives.

"What? You don't understand what physics means, then you're stupid enough to see that I don't have this apple in my hand, it's because gravity hits your head, what? If you don't know what gravity is, why don't you listen to a magical physics lesson? ”

In this way, word of mouth is close to a pyramid scheme, and by the time the second Friday comes, the self-study classroom is already overcrowded, and those who can't sit stand and those who can't get in are crowded in the corridors.

"Ladies and gentlemen, I'm glad you're interested in science, but remember that you're here to learn magic, and remember to focus on magic."

Looking at so many students in the audience, Lubi always felt that he had done something very strange, he felt that he needed to be a little more restrained, in this world it is enough to be addicted to science, people are here to learn magic, when the students go home to meet their parents after a semester, the parents find that the child has learned a lot of physics knowledge and are afraid to come and strangle him.

Ruby's lessons have nothing to do with magic, but they make the students understand many unknowns.

"Mr. Lubi, I have a question, do you have any evidence that the continent under our feet is round?"

The people who came to listen to the lecture were not all students who were eager to learn, at this time Swart, who was sitting next to Teacher Bai Yu, opened his mouth and asked, it is intolerable that there are teachers on campus who are more prominent than him, and the Teacher Bai Yu he has been pursuing is also interested in listening to the class, which makes him feel that he has to do something, although the knowledge that Ruby said makes sense, but it cannot be ruled out that he just said something to make the students feel unaware so as to achieve the purpose of wanting to be noticed.

"To be precise, it's a planet, but you don't have such a concept, so you didn't give a decent name to the planet you live in, as for the evidence, if the planet under your feet is flat, the sea level will not be arc-shaped, and the students who have been to the beach should have seen the appearance of a ship coming from afar, and the students who don't understand it should simulate it with water balloon by themselves."

"It's... You can't prove that these two things are related. ”

Swart was stunned by Ruby's words, but he still asked unrelentingly.

"Then I'll say one more thing, you should know if you stand high and see far away, if the planet is flat, no matter how high you stand in the case of nothing blocking your view, you can see the same far, if Mr. Swart can find a completely flat planet, you can verify my statement."

Ruby said a big argument about the fact that the earth is round, and Swart no longer questioned it after listening to it, what Ruby said was justified, and it was his fault if he continued to dwell on it.

"Ruby, I still have a problem!"

Eve, who was sitting in the first row, stood up decisively, because she herself had argued at home that the continent was round, and it was also from the point of view of sea level. The pink-haired girl was happy for no reason, but she still had many questions to ask to see where the end of Luby's knowledge was.

"Just ask."

"Well, why does the sky and sea look blue?"

If the continent is round, Eve can still do her best to verify the sky and the sea, she has no way, if Ruby can even answer these questions, then it is really invincible.

"The sky looks blue because of an optical phenomenon called Rayleigh scattering, I won't talk about it for you, if you're really interested, you can come to my office after class."

Ruby only said it at the beginning, not because he was lazy, but because of the particles, and if he said something like a light wave, he would only get a bunch of Akua faces.

"As for the sea, it's simply because the water absorbs some of the sun's color..."

"Stop, wait, does sunlight have colors?"

Eve interrupted Ruby's words with a surprised face, because his answer was beyond the cognition of the otherworldly, everyone knows that sunlight is a good thing, and it is impossible to understand it when it comes to color, and the Holy Light of the Holy See can be seen to be conspicuously white, but sunlight and Holy Light are two different things.

"The color of the sun is the rainbow you see, and it's very easy to verify."

Ruby nodded, and as he spoke, he took out a piece of transparent glass and placed it on the podium, just outside there was a beam of sunlight shining into the classroom, and through the glass, the students could see the projection of seven colors.

"This should be easy to understand, sunlight is composed of red, orange, yellow, green, cyan, blue, violet seven colors of light, seven wavelengths... Let's talk about penetrating power, light with strong penetrating power is easily absorbed by water molecules

In the end, only purple and blue are left in the seven colors, and the human eye is not sensitive to purple, and will automatically choose to see blue in comparison, which is why the sea water is blue. ”

"Oh, oh!"

Every sentence Ruby said was human words, but in the eyes of Eve and the students, it was a nonsense, and in the face of Ruby Eve, who had said so much, he subconsciously applauded, and few of the other students understood it, and applauded together with an unaware mentality, so the whole classroom applauded.

The self-study class was originally a whole day, and the students were willing to listen to Luby and talk about it, and in a blink of an eye, it was time to get out of school, even if they wanted to continue to listen to Luby talk about some strange knowledge, but there was so much knowledge of the earth, and they could only agree to talk about it next week, and it was obviously the most idle self-study class in the academy but it unexpectedly became the most attended class.

"What's the matter, Eve-san."

After the lecture ended, Lu Bi saw a small pink shadow secretly follow, this pink hair is still very recognizable, and the whole school is a person with such hair color.

"Didn't you say you were interested in going to your office and asking questions?"

Eve began to treat Ruby completely as a baby, for so many years, she had not met a person who could be like-minded with her, and now there is such a person in the world, so it is natural to keep an eye on it.

"I'll just say it in passing, I didn't expect anyone to be interested, aren't you afraid that your brain won't be enough?"

Ruby is still a little strange, although those students are quite interested in physics, but it is also the knowledge at the elementary level, and the knowledge behind it can be said to be extremely brain-burning, he does not recommend that students learn such knowledge, or that sentence, magic is what they really need.

"I'm not afraid, I've been interested in these things since I was a child, and I made them myself."

Eve followed Ruby all the way to the office, and threw a number of self-made props onto his desk.

"Is this a telescope? You can make such a thing. ”

Ruby picked up the prop that Bard had said was worthless before, looked at it, and praised it heartily, obviously a farsighted magic can solve the problem, but she is willing to spend time and effort to make such a prop, it seems that this little girl is really interested in science.

"You know what? This is very powerful, but my father said that this is not as good as magic, which really me off. ”

The props made by yourself are favored! Unlike the flattery of her family, Eve could feel that Ruby was genuinely praising her, which made the smile on the pink-haired girl's face even brighter

In the next few hours, Lubi told Eve a lot of orthodox physics knowledge, and even took some dry food to deal with it, Eve's dedication to science was beyond Ruby's imagination, such a rich lady was willing to eat dry food with him, should it be said stupid or cute.

"Miss Eve, take the liberty of asking, is your surname Einstein?"

Rubi was amazed by Eve's scientific talent, he could understand it by simply saying a word, and if it was a little more difficult, he could be sure that such a person would definitely be a Newton and Einstein level person on Earth, but unfortunately he was born in another world, if she was given more basic physics knowledge, maybe she would be able to figure out nuclear weapons or something by herself in a few decades.

"No, my surname is Starry Night."
