Roman Slave Owner

Director, I want to ask a question too.

At this time, Mr. Metellus raised his hands and shouted.

This roar really shocked everyone and stunned everyone else.

Su La looked at this old guy viciously, how dare you rush to ask questions.

Mr. Metellus raised his head unceremoniously. This is an academy, not a place for you to show off your prestige.

Li Wei felt a little pain in his head, Okay, I have questions one by one, and the voice should be quieter next time.

Dean, why can glass see things that our naked eyes can't see? And what do you think light is? Is it moon atoms or sun atoms or something else? Do you agree with Democritus' atomic theory?

Good man, Mr. Metellus asked four questions like a cannonball.

Well, there are a lot of questions, let's first talk about what is light? I partially agree with Democritus' atomism, but I don't think light is composed of moon atoms or sun atoms, but photons. This It is another special particle besides atoms.

For example, the reason why we can see this table is because photons are irradiated on the table and then reflected. Some of the photons are reflected into our eyes, and we see the table. The reason why glass allows us to see things that the naked eye cannot see What you get is because of the phenomenon of refraction.”

Levi said.

What is reflection? What is refraction?

Dolabela didn't raise her hand, but stood up and asked.

His behavior of rushing to ask questions attracted other people's glaring looks, why is this guy so unruly.

Li Wei had a terrible headache, if he didn't do anything about it, the classroom discipline would be over.

In the future, if you ask questions, you must raise your hand first, otherwise you will be deemed to have given up the qualification to ask questions.

Levi said.

Dolabela sat down triumphantly, as if she had won a big battle, which attracted the unanimous contempt of others.

A bunch of shameless guys, Li Wei complained.

What is reflection and refraction? This question is more complicated. I have a detailed description in the textbook I distributed. It is in the last chapter of the first volume.

Levi said.

Textbooks? Where are they?

Dorabella asked.

Li Wei has the urge to scold your mother, you are not my student, why should I send you textbooks.

Only then did they realize that the students sitting behind them were all holding a roll of papyrus with densely packed text written on it.

Su La turned to a doctor behind her, stretched out her right hand and looked at him lightly.

Seeing this, the doctor was in a cold sweat, so he obediently offered the papyrus in his hands.

Dorabella bluntly snatched the papyrus from the person behind, seeing that Li Wei wanted to hit someone, so she would definitely not let this guy come next time.

Pompeo turned his head and smiled, his handsome face made the heart of the midwife behind him thump like a deer.

so hot!

She blushed and handed him the papyrus in her hand.

thanks.

Pompey said with a smile.

The midwife almost lowered her head into her chest, and said yes like a mosquito ant.

A bunch of bandits.

Seeing that those generals borrowed textbooks from his students one after another, including some veteran knights behind him, Li Wei couldn't help cursing.

As the book says, when a photon hits an opaque object, it will reflect. In a completely ideal environment, its angle of incidence waits until the angle of reflection. What is the angle of incidence and angle of reflection is introduced in the book, this is not What we're talking about in this class, what we're talking about is the refraction of light.

Levi said.

He took out a wooden basin half filled with water, and put a sword in the basin.

Is this sword straight?

Levi asked.

yes.

His students said one after another.

Then take a look, isn't it bent in the water?

Li Wei signaled Duilius who was next to him to walk towards those students with a wooden basin.

Duilius blushed with excitement. At first he thought Li Wei was just a playboy, and running a school was just for fun.

I didn't expect to speak so well, he can still tell if someone really has the goods.

If Li Wei really became a great philosopher of a generation, would he become his disciple and become famous in history.

Just like Socrates and his disciple Plato.

Just when Duilius let himself go, he looked at Li Wei suspiciously, what was he talking about just now? He didn't hear clearly.

Li Wei looked at this guy angrily, what the hell is this guy doing.

Show this to the students.

Li Wei said holding back his anger, there were too many accidents in class today.

Duilius immediately understood what Li Wei meant, and he walked towards the students with the basin of water.

It really is curved.

Some students said after reading it.

They may have seen this kind of thing before, but they never seriously thought about why.

After Li Wei reminded them, they found that this was indeed the case.

After all the students had observed it, Li Wei asked, So is the sword really curved?

Those students shook their heads one after another, how is it possible?

Li Wei asked Duilius to take out the sword, and the sword was indeed straight.

This is the phenomenon of refraction of light. When light passes from one transparent medium to another, light will be refracted.

Fake! Absolutely fake!

At this moment, a roar suddenly sounded in the classroom.

Li Wei looked at the source of the sound angrily, and found that the bastard Dorabella was holding the roll of papyrus and shouting loudly.

Tell me what's wrong?

Li Wei held back his anger and said.

How can sunlight be composed of seven colors of light, it's impossible!

Dorabella said loudly.

That's impossible! How could sunlight be composed of seven colors of light?

someone asked.

How can it be impossible? It's written on it.

Dorabella pointed to the papyrus and said.

A group of heads immediately moved over.

Yes, it does say that sunlight is composed of seven colors of light.

How is this possible? How can sunlight be composed of seven colors?

...

Everyone discussed and said, and then looked at Li Wei with doubts. Could it be that this guy is lying.

Dorabella raised her head triumphantly, as if grabbing Li Wei's sore foot.

Tullius breathed a sigh of relief, he was indeed lying, and Li Wei had no skills at all.

Duilius looked at Li Wei worriedly, but nothing should happen.

Li Wei looked at Dorabella with a look of a fool, which made Dorabella feel quite uncomfortable.

Is there anything wrong with what I said?

Dorabella asked.

Can you read the last sentence of that sentence?

Li Wei said lightly, a group of ignorant idiots, let you know how powerful modern people are today.

Just read it, there is nothing to be afraid of.
