"Oh?!" Fan Qi was shocked, "Is this... this is also your idea?"

"It's not me, it's Tan Ying. Why is the shadow northerly? It's also the first problem that Tan Ying came up with."

"Tan Ying? Who is Tan Ying? Is this here?"

While searching the whole audience, Huang Er wiped his sweat and bowed his hands first and said, "Si Ye, the student has already explained that this statement was realized when talking to his friend. His friend was Ying Yue and his companion to read Tan Ying."

But a deafening roar came.

"Don't let your mother go!!!"

Ying Yue's case became angry and pointed at Huang Er's throat and scolded:

"Dog thief!! How dare you hang over the market here? Are you afraid of breaking your eggs?!!

"Talk with you? What to talk about? It depends on your boasting baby?

"Stealing is a thief! I use all my guarantees, Huang Er is a thief!

"You are the only one who bullies Yue, but you are the one who bullies Ying, and you are the only one who can do this in your Chunshen family?!!"

Once this scolding came out, the audience was immersed in silence.

But my mind is full of voices-

The city is singling over the city...

Boasting the eggs and boasting the eggs...

A bachelor's degree who can scold such harsh words will probably not be too bad...

On this side, it was too late to pull Tan Ying, so she had to cover her head.

Indeed, it's time to stand up and grab the place.

But in the face of so many academic experts, I swung my shit, pee, butt, so I was so out of control...

Brother, you're afraid...

"Good curse!! OK!" But when Pang Mu got up, he attacked the case and praised him, "If you really want to repay your grudges, you will be angry. This is a true gentleman! This is a real man! What I said!"

In fact, it's not just him.

Others who have studied hard can feel inexplicably sour.

Maybe it's because it's so impressive.

When I heard Ying Yue’s extremely rough street scolding, even my meridians became much more unblocked.

The market has been lifted and the eggs collapsed...

Is my Daqin's spraying technique so perfect?

On the other hand, Si Qinghuang then said: "The problem of shadow was the first to Tan Ying figured out, but he only cared about his own understanding and was unwilling to share it with others. Such a person who cherishes his loyalty, the students really don't believe that he would tell Huang Er generously."

Huang Er was already sweating profusely at this time, but he still stood sideways and said, "You leave first during the conversation, how can you know what happened next?"

Bang!

"Dog thief!" Ying Yue lashed out with anger and pointed, "Reduce eggs!!!"

"You...you are crazy...I won't argue with you..." Huang Er didn't dare to look at him at all, and just bowed to Fan Yi, "Si Ye will naturally observe the twists and turns of right and wrong."

"No need." But seeing Fan Ji shook his head gently, "This is only talented."

After saying that, he turned to the handsome man behind Ying Yue who could not even be covered.

Tan Ying hurriedly stood up and saluted: "Student Tan Ying, I have met all the teachers."

In fact, he didn't need to say much, everyone at the scene had already peeped at his appearance countless times.

But when Tan Ying stood up at this moment, she saw her nearly eight feet tall figure, like a horse, and the scholars couldn't help but exclaim.

Even Fan Ji was slightly shocked.

The way of heaven... Such a great way of heaven... can actually create such a handsome masterpiece.

But he still held his airs down and asked slowly: "If Huang Er really stole your theory, why didn't he point it out just now?"

"The teacher did not say that he could speak freely, so the students only listened respectfully." Tan Ying replied respectfully.

"Aren't you afraid that Huang Er will steal your things?" Fan Qi asked.

"There is no new theory under the way of heaven. Students who were heard by Huang Er thieves were only to inherit the understanding of the ancestors. Therefore, Huang Er thieves were not students, but ancestors." Tan Ying replied calmly, "Further, students believe that the teacher will have their own discernment."

"Mr. Tan, if you speak too respectfully, it sounds like a scent. Instead of crafting beautiful sentences, it is better to set your goals and show others." Fan Yi seemed not very satisfied with Tan Ying's answer, and just said with a look, "And my way of distinguishing right from wrong is to ask you the question I had asked Huang Er again, how about it?"

"Please, teacher."

Fan Yi immediately calmed down.

A brief conversation in a brief conversation begins here.

Fan Ji: "Why are there any change of day and night?"

Tan Ying: "Besides the earth revolves around the sun, there is a spin like a top. Therefore, every place on the sphere will take turns bathing in the sun, and the direction of rotation is from west to east. One week is a day."

Fan Ya stopped here.

The audience also fell into thought.

It is normal for students to not understand this model for a while, but teachers already have the foundation they just did, so it is not difficult to figure it out.

It is difficult to prove the theory of astronomy, so it has always been self-consistent.

Although it is difficult to accept intuitively by spin, it is a barely enough to explain the change of day and night.

At least Tan Ying really considered this matter, but Huang Er didn't.

As Zhu Xuebo nodded, Fan Qi spoke again.

Fan Yi: "How do you know it is from west to east?"

Tan Ying: "The sun rises and sets in the east."

Fan Ji: "Why can't I feel the spin?"

Tan Ying: "A baby was born in a carriage that was moving forward at a constant speed forever, and he spent his entire life in a carriage. Can he still feel that the carriage is moving?"

Fan Ji: "He can look outside the car and tell the car is moving at a glance."

Tan Ying: "Then the teacher can also look up at the stars, and after watching for a long time, you will know that the earth is spinning."

Fan Ji: "...Well, it's very good... Can I continue to ask?"

Tan Ying: "Please, teacher."

Fan Ji: "Why does the spin start?"

Tan Ying: "It can only be said that it has been there since the beginning, and the depth of students is only here."

Fan Ji: "It's enough. The next question is why there are four seasons."

Tan Ying: "Because the ecliptic and the equator do not overlap, there is an angle."

Fan Ji: "You might as well explain in detail."

Tan Ying: "The ecliptic, that is, from the earth, the trajectory that the sun has taken in a year is also the orbital plane of the earth's orbit around the sun.

"The equator, that is, the trajectory plane with the longest perimeter in the spin of the earth, is also the boundary plane of the northern and southern hemispheres.

"These two sides do not overlap, there must be an angle, otherwise the sun will always hit the equator directly, and the light will be the same all year round, so there will be no four seasons.

"Evolving it into a figure means that when the earth is spinning around the sun, it is like a gyro that always falls to the ground.

"With this figure as an illustration, it is not difficult to imagine that as the earth changes with the position of the sun when it revolves, the point directly hitting the earth will also change around the equator, and the light obtained from various places will also change again and again.

"During this period, the day with the most light and the longest day is the summer solstice, and the day with the least light and the shortest day is the winter solstice.

"This is the cause of seasonal change. Although it is the cause of fantasy, it is also the only cause that students can think of.

After the Tan Ying was released, the sound of abruptly stopped.

The audience was full of thoughts and speechless for a long time.

Equator, ecliptic, circumference.

Trajectory, location, geometry.

It takes too much knowledge and imagination to understand the principles mentioned by Tan Ying.

Not to mention the students present, even those who are studying, there are very few people who can build a picture in a moment.

They even felt that Tan Ying was bluffing people and deliberately used some complicated descriptions to cover up the flaws of the theory.

Until Fan Yi suddenly became stunned and raised his arms and shouted:

"I see!

"When I was still young, a South Vietnamese told me that their shadows were sometimes north, sometimes south, sometimes noon, and I still couldn't understand this matter.

"But he guaranteed the head, and he wanted to hit the wall to show his ambitions.

"I see!!
