The sun is setting in the west.

All I can say is......

Coming out of the Princess's Mansion.

Zhang then realized how shallow his previous research was.

Although the views and conclusions put forward by Mr. Li may not be completely correct.

But......

Obviously!

In the experiment, he is indeed inferior to Li Lao.

Especially each of the experiments documented here.

Moreover......

Subsequently......

Li Lao also said about particles, putting forward a hypothesis.

That is, charcoal is also used, but why, for example, if you say that the ancients smelted copper and iron, there was a particularly obvious difference in the times?

So Li Lao speculated that there was also a difference between the hands of the particles holding hands and arranging them closely.

For example, copper ore may just be held by one hand, so it only takes a little heat to make the copper.

As for iron ore, two hands are holding two hands, so naturally, the heating temperature will be a little higher.

This is one of the reasons why bronze appeared earlier than iron.

As for why copper should be simpler and iron harder.

Li Lao also explained that it was possible that copper only combined with one particle.

As for iron, maybe two irons are combined with three particles.

The combination of iron and copper is much more complicated, and it is precisely because of this complexity that more external forces are needed.

And why it is heated, there is a change.

Li Lao also explained that heating is conducive to disconnecting the previous connection, and then forming a new connection.

Or is it......

On the one hand, heating is good for disconnection, and on the other hand, the friendly relationship between particles is also different.

After heating, the particles that were originally bound to iron may run away with the new particles and no longer play with iron, so they ...... Eventually, iron was ruthlessly discarded and reverted to iron composed only of iron particles.

For this set of theories of Li Lao.

Zhang Sui could only say that he would be suspicious.

Anyway......

Because I look at the picture and speak, and I make up the story when I have the facts, there must be nothing too wrong with the logic.

Now the problem is......

How can it be proved that these are all right or wrong.

In fact.

After Zhang Sui left, Li Chong was also thinking about this problem.

After all......

Nor can he say nothing.

Of course!

That is, I simply thought about it for a while, and then ......

Soon he hugged the waist of the Silla maid and went happily.

Because as far as Li Zhong knows, even in later generations, it will not be possible to observe the structure of molecules and atoms with the naked eye, let alone now.

……

After going back.

Zhang Sui also fell into a bottleneck all of a sudden.

In fact......

He didn't want to believe everything Li Chong said, after all, he was a scholar, and he wasn't the kind of stupid person who didn't know what he asked, and he would believe whatever the teacher said.

If you want to convince a top student, unless, you can give him convincing evidence.

Since Zhang Sui didn't have any ideas himself, and even, when he came back this time, he was actually a little hit by Li Chong.

No way......

can only follow Li Chong's experiments and try them one by one.

Anyway......

Now he doesn't have any other new ideas.

Moreover, if you want to refute Li Lao, you should start from Li Lao's experiment to find out the flaws.

The following month......

Zhang then began to follow the experiments proposed by Li Chong and restored them one by one.

And Li Chong used this month to start thinking about how to measure the speed of light.

Let's be honest.

He'd seen it, but forgot.

And......

Since it involves cycles, Li Zhong can only say that he is not very sensitive to cycles.

Why is it possible to measure the speed of light by knowing the rotational period?

This really puzzled him.

Of course!

Wanting to measure the speed of light is just a hobby.

In fact......

Even if it was to let Datang know how fast the speed of light was, it seemed that it was useless.

……

In the small courtyard of the Silla maid.

Li Chongcai would not admit that it was because Silla was so popular with him, so he deliberately set up a separate courtyard for her.

Now, Li Chong is studying how to measure the speed of light.

He knew that one way to do this was to pass light through the gaps in the rotating gears and then calculate the speed of light.

But the question is......

Why is it possible to measure the speed of light by allowing light to pass through the gaps in gears?

At least, no matter what, it will take some time.

Li Zhong is really not very good at this kind of spinning thing.

The arc, the angle or something, I can only say that it is a headache to watch.

When Li Chong frowned and thought about these things, this Silla maid also spontaneously came to rub Li Chong's scalp.

Li Chong looked at the Silla maid.

I thought to myself: Be reasonable, you crossed the line!

Because it's something that only Lishi can touch.

But think about it, Li Lizhen is also seventy-eight this year, almost eighty years old, of course, it is impossible to give him this again.

Think about it this way......

He thought it was better to forget it.

Well!

There is no need to make such a fuss.

But no matter how good she behaves, this treatment can't be improved.

If you think about it now......

He did have a little bit of affection for the Silla maid, which surpassed his previous rules of doing things on an average basis and everything on an average basis.

But......

He didn't see that she was a Silla person, and it was indeed not so easy to play with those widows.

Besides, people have their own small circles, and whether they play with you or not has to say another thing.

This is perhaps the most important reason why Silla is so close to herself.

The main words......

Those widows are all of the same race, so no matter what they do or what they talk about, they can do it and talk about it.

And you're a Silla man......

Of course!

It's not that those widows reject her very much, at least Li Chong didn't see such a situation.

It's just that......

Compared with mixing with those widows, she obviously chose to mix with Li Chong in the end.

】

Li Chong is basically with her now unless he wants to go to someone else's.

And she's obvious!

In such a situation of being unaccompanied, it seems that there is only one person who can rely on Li Chong.

"Rotation Period."

"Time."

"Radian."

"Distance."

I saw Li Chong muttering to himself while enjoying the other party's head massage.

And the other party also repeated Li Chong's words, and then asked without pretentiousness at all, and even asked with a little innocence: "What do these mean?" ”

Li Chong said: "I don't know either. ”

Let's be honest......

With such a beautiful woman by his side, he really couldn't calm down.

Of course!

Actually, these are all excuses.

He just wasn't good at it, so he chose to escape.

Hugged Silla from behind into his arms, beautiful appearance, and quite good figure, at least d, hey, how is this speed of light calculated?
