This is nothing new for many officials in the Tang Dynasty and the students of Guozijian.

Li Chong's idea naturally attracted a lot of discussion.

This Li Zhong dares to propose a unified weights and measures today, and tomorrow he will dare to be His Majesty.

This is the idea of the eldest grandson Wuji.

Of course!

More people are looking at this free-fall movement, and ......

In the end, Li Zhong also came up with a small problem, saying that if a larger stone and a smaller stone fall from the same height at the same time, who will fall faster.

Then a short story was also assumed, "Two Children Debate the Stone".

To this end......

The students of Guozijian, who were idle and painful, also moved the escalator, climbed onto the roof, and started the experiment themselves.

Since at the beginning, there was also some argument between the two sides.

So in the end......

When the experiment was done and the results came out, some people couldn't help but come back to their senses. Li Chong seems to be scolding them for being children.

Although Li Chong does not necessarily mean that.

But......

The students of Guozijian themselves have turned themselves into those two children.

And......

Many of them really think that it should be bigger, and the heavier one should land first, there should be no doubt about it.

But in the end, when it was made, I found that the difference between the two didn't seem to be very big.

Even......

It should be said that there is no difference.

All I can say is......

This problem is not good, you only give two options, but there are three answers, isn't this digging a hole for people?

And then......

Some people began to complain, after all, this is because some people said that if it wasn't for the heavy one falling first, he wouldn't wash his hair for two months, who would have thought that this was not an answer at all.

But......

For the sake of his reputation, he can only really not wash his hair for two months.

After all, in ancient times, if a person had no credit, it was really difficult to move an inch.

If you follow the rules, you might even be able to earn yourself a good name, right?

Although this is an inconspicuous matter, it may not even be considered a serious thing in the eyes of the ancients. However, it is undoubtedly quite interesting, and it also adds some fun to the otherwise boring reading life.

As for the teacher of Guozijian......

For this kind of chaotic thing, you can only turn a blind eye, besides, Datang is relatively open.

It's not a good thing to think about it and see more.

And......

To tell you the truth, they didn't know it would be like that.

After doing the freefall experiment.

Next......

Li Zhong did another Magdeburg hemispheric experiment.

Of course, it is certainly impossible for the students of this experimental country to prepare the required experimental materials themselves, so they ......

This time, the experiment was mainly carried out by Li Chunfeng.

All I can say is......

….

On the day of the experiment, many people in Chang'an City also gathered around to watch the excitement.

Because the location of the experiment was outside Chang'an City.

So......

It can be seen that many people in the Tang Dynasty are holding hoes with both hands, pouting their buttocks and watching curiously.

At the beginning, the iron ball didn't need to be broken by hand at all, and it would be split into two halves.

Then, after all the gas in it was pumped out, a dozen horses had to be used together

Pull to pull away.

What does this mean!?

Li Zhong then used the paper to make some 'reasoning,'.

At last......

The concepts of atmospheric pressure and gas pressure were then proposed.

The third month.

The experiment was conducted in a vacuum to see if a pebble landed first or a feather landed first.

It is a beautiful transparent glass tube that is worth at least a million in the eyes of outsiders, or is worth no price.

The result of the experiment is also to refresh everyone's cognition again.

No one would have imagined that the fluttering feathers could fall as fast as pebbles in that tube.

Thereupon......

It seems that slowly, it has become a routine.

That is, at the end of each month, the Academy of Sciences will conduct some experiments for the students of Guozijian in Chang'an.

And the specific content is to be idle and hurt, and to do something that seems to be useless.

Luoyang.

After Li Chong handed over the experiment to Li Chunfeng, of course he was not idle.

It's not ......

Ever since he saw Kang Xinggan's steam turbine, Li Chong began to think about the idea of power generation.

The main thing is that this steam turbine wants to make it yourself, not too easy.

Even more simple than a piston steam engine.

Now there are small steam turbines, and then the natural magnetite is also obtained from a friend of Sun Simiao's monastics.

Let the craftsman polish the magnetite into the shape of a generator, although Li Chong has never made a generator himself, but he has never eaten pork, has he never seen a pig run.

After some attempts, it is basically finished, and now the question is, how to make this light bulb?

Because if you can't make a light bulb, then there is no way to test whether you have actually succeeded in generating electricity.

Do you want to use your own hands to try electricity?

However, not to mention that the current should be very small, even if it is very large, what if you give yourself electricity?

If it's another funny protagonist, it's estimated that the servant has been asked to take the wire to try the effect.

However......

Li Chong is certainly not the kind of funny.

The other party also quickly sorted it out, and then looked at the pile of things on Li Chong's table.

"Not done yet?"

Although Wu Meiniang didn't know what Li Chong was doing.

Li Chong said, "As we all know, the wick of this light bulb is made of tungsten wire, but where can I find tungsten wire now? I wonder if I can do it with other metals?"

As he spoke, Li Chong stared at the other party's three thousand green silks.

Speaking of which......

Can this strand of hair conduct electricity?

Li Zhong still remembers that when he was very young, he heard the story of Edison's invention of the light bulb. In the end, it was also after thousands of experiments that I finally found a suitable material for the filament.

Also, if Li Chong remembers correctly, the light bulb should be filled with nitrogen or some kind of gas.

But......

It shouldn't be a big problem, after all, he also knows that it is like filling this inert gas just to not react with the air.

It plays a role in extending the life of the bulb.

However, he is not in a hurry to prolong his life now, and it is already good for him to be able to do it.

Thinking about it, and then Li Chong planned to pull out a hair of the other party.

"Ah! What are you doing pulling my hair out?"

"Ahem! I'll borrow it."
