Isekai Nonbiri Nouka

Lou was roaring when he was eating.

Research on the metastasis has not been successful.

In the last few days, wrinkles have moved between the eyebrows.

It is unwilling to make such a face while eating precious chestnut rice.

But I can't help.

He couldn't understand Lou's research at all.

The hurdles are too high for me, the flow of magic, the interference of spirits, the position of the stars.

But can I just leave my wife worried?

Is there anything I can do as a husband?

I talked to Lou after eating.

"Lou. Could you explain to me what you're having trouble with?"

"Huh? But ..."

"I don't think I can understand or come up with any solutions, but I can put my ideas together by explaining it to others."

What I can do.

It is to be a listener.

"So, these two numbers seem to be based on the sun, but the amount varies depending on where they are installed. I don't know why."

"How is it different?"

"Um, in a nutshell, in the first place, the criteria are ten and they increase one by one. So in the second place, the criteria are eleven and two by two. Let's go "

"Houho"

"In the third place, the standards are increased by three at eleven .... In the fourth place, the standards are increased by two at ten. There are two things that I do not understand Oh, actually, there are more and more numbers, because one or two are just for clarity. "

"Thank you. Two numbers based on the sun that changes depending on the installation location ... Ordinarily it is rotation and orbit when thinking as an element."

"……e?"

"No, rotation and revolution"

"what is that?"

"e?"

……Ah.

This is a fantasy world.

The sun could move, and the ground could be flat.

Anyway, there are two moons in the night sky.

"Sorry, forget me"

"No. Details"

Lou's eyes were a bit scary.

I taught Lou about rotation and revolution.

Rotation is the movement of the earth.

Revolution is the movement of the earth around the sun.

I taught it very easily.

Because there is a seasonal change, it is because of the rotation with inclination to the sun and the elliptical orbit slightly shifted from the sun.

"I want to be such an idiot, but I can explain various things that I could not explain so far."

Was good.

The same ground motion theory as in the previous world passed.

In other words, the earth is spherical.

However……

"Is it not known that the earth is spherical?"

"Sometimes it was said that, but nobody could prove it. Now it's a common belief that the earth is a loose hemisphere."

......

I asked Hakren as a representative of a dragon flying around the sky.

"The earth is spherical."

Lou collapses from her knee.

"By the way, do you teach the children?

There's nothing wrong.

But I'm chasing Lou.

Lou, are you OK?

Can you get up?

No?

I sleep today.

all right.

From the next day, Lou did not growl at the meal, but began to look a little farther away.

"I'm gonna go to Hakuren's class too."

I didn't know how to respond, so I decided to eat silently.

I'm sorry.

I am powerless.

It took about ten days for Lou to be in good shape.
