“Hahahahahahahahaha!!

"He didn't lie to me, it can be like this!

"Hahahahaha! It's amazing!"

Fan Ya was laughing wildly, unable to stop laughing wildly.

The white beards, like weeping willows, danced like a strong wind passing by.

At this time, he was still like a clever boy who had been holding back for ten years before he could get avenge.

Others looked even more confused.

I haven’t figured out the principles of the Four Seasons yet, so why did I rewind?

Sometimes it is northerly, sometimes it is southerly, sometimes it is shadowless at noon? What kind of hell is this on earth?

But even if they still couldn't understand, Fan Jian's pleasure as if he was revenge was not able to deceive others.

More importantly, he is Fan Yi, Fan Zi, the supreme emperor of the Mo family in Qin, and the leader of mathematics and physics in the world.

Such a person has a problem that has troubled him throughout his life.

Just then, I solved it.

And the one who solved him...

Zhu Xuebo couldn't help but be shocked by Tan Ying.

Their feelings at this time were just like the one who learned from the King of Learning at that time—

Although I don't understand the principle, I was shocked.

Even Han Sun didn't realize that he had lost his laziness and desolation, focusing his dissipated gaze here.

But Tan Ying's face was solemn and she didn't notice this at all.

It is because of Fan Ji that he has realized the existence of the Tropic of Cancer.

Previously, Tan Ying told Ying Yue that the shadow of the northern hemisphere was northerly and the southern hemisphere was southerly, which was of course inappropriate. Fan Yi naturally found the loophole and refuted Huang Er.

The correct statement about shadow is: except for the North and South Poles, north of the Tropic of Cancer, the shadow is always north, south of the Tropic of Cancer, and the shadow is always south.

As for the two, because the earth is "rooked and rotated", the point where the sun directly strikes the earth will move back and forth within this range.

Therefore, the sun is sometimes southerly, sometimes northerly, and sometimes right in the sky.

In this way, whenever the sun shines directly on the Tropic of Cancer, it is the winter solstice and summer solstice.

Whenever the direct point passes across the equator, it is the vernal equinox.

There is no doubt that the latitude of these two regression lines is the angle at which the earth is tilted, and it can only be the angle between the ecliptic and the equator.

23°26′.

ah……

At this point, the sandalwood looks like a different life.

Come back.

All the geographical knowledge buried deep in memory and under the trivial matters in the world have come back.

Why is the shadow northerly?

It was just such a simple question at first.
