In the history books of later generations, the first Datang Academic Exchange Conference was given extraordinary significance.

There are even many scholars who believe that this is the beginning of the modernization of the Tang Dynasty.

All those who attend the academic exchange meeting today will leave a mark in the history books.

As for Chen Dali and Tong Zhou, who stood on the stage, not to mention.

"Everyone must be curious, what is going to be done at today's academic exchange meeting?"

Although Li Kuan gave the two most important reports to Chen Dali and Tong Zhou, it was impossible for him to really care about everything.

So when everyone was seated, he first stood on the podium and made a cameo as the host.

"Actually, today's content is not so complicated, just show you an item called a microscope, and then introduce you to the microorganism observed with a microscope. Finally, please go outside the door to watch an experiment. ”

Li Kuan spoke lightly on the podium.

However, many people in the audience immediately talked about it.

Although he didn't know what a microscope was, since Li Kuan dared to say that he had observed microorganisms with a microscope, the meaning of this matter was different.

Thinking of the boiling "microbe" controversy in Chang'an City during this time, many people have a trace of expectation on their faces.

Because of the "Chang'an Evening News" and other newspapers, few of the people present had never heard of the word microorganism.

Many people have even been personally involved in discussions about microbes.

Looking at what Li Kuan means now, this is the final conclusion for this matter.

If he could really prove the existence of microorganisms, then this academic exchange meeting would be very different.

"Okay, I think you're really interested in seeing what this microscope looks like. Why do you use it to see microorganisms that you can't see with the naked eye? Next, we will ask Chen Dali, a seventh-level worker in the glass workshop and the maker of the microscope, to explain the situation of the microscope. ”

After Li Kuan finished speaking, he turned around and motioned for Chen Dali, who was standing next to him, to come over and start speaking.

In this era, there are no projectors, and it is not so convenient to give a speech.

Fortunately, Guanshishan Academy has made a lot of preparations for today's exchange meeting.

Just as Li Kuan finished speaking, some students came to the podium with a few large blackboards with microscope images drawn.

At the same time, some students moved a row of microscopes to the front of the podium.

"Aye, this Li Kuan doesn't take everyone seriously, right? For such an important meeting, even His Majesty came, and he arranged for a craftsman to come to the stage to make a report? ”

Changsun Chong muttered a little dissatisfied.

With the exception of the first two rows, there is no fixed position on who sits where.

Therefore, Changsun Chong has the opportunity to sit next to Changsun Wuji, otherwise, the difference in status between the two of them will naturally lead to the situation where Changsun Wuji sits in the front row and Changsun Chong sits in the back row.

"Chong'er, don't you think Li Kuan arranged it like this, maybe he has ulterior motives? Even if he didn't know that His Majesty would come back beforehand, but the ministers of the court would participate, he should have known about it. In this case, he still arranged for a craftsman to come to the stage to give a report, do you think this will be his mistake? ”

An old fox like Changsun Wuji, the angle from which he looks at the problem is naturally not comparable to that of Changsun Chong.

Although he didn't dare to be completely sure, Li Kuan's arrangement must have wanted to improve the status of the craftsman in Datang.

Shinong industry and commerce, this saying has been passed down for thousands of years.

Li Kuan wanted to elevate the status of craftsmen, so that there would no longer be a difference in priorities between Shinong and industrialists, but it was not something that could be done overnight.

"In Chang'an City, the status of craftsmen has been greatly improved compared to before, isn't that enough? Could it be that he Li Kuan, he really wants craftsmen to be on an equal footing with scholars? ”

Eldest Sun Chong had a surprised expression on his face.

Obviously, Li Kuan's approach is beyond his comprehension.

"The place with the most craftsmen is the various workshops in the Chu Palace, and Li Kuan naturally hopes that the higher the status of the craftsman, the better, so that his influence will be greater."

The eldest grandson Wuji speculated on Li Kuan's plan according to his own thoughts.

"The most critical components of this microscope are two specially ground lenses that magnify objects by more than 20 times. When we put these two lenses together on the microscope......"

The people in the audience talked a lot, but Chen Dali on the stage was attentive to explain the principle and production method of the microscope.

He is not worried that after someone learns this principle, they will copy it.

Not to mention that glass making skills are the exclusive secret of the Chu Palace, even if you can produce glass, you may not be able to produce glass that meets the requirements of microscope lenses.

Taking a step back, even if you can produce glass that meets the requirements of microscope lenses, it does not mean that you can polish the lenses to the standard.

If you give him a hundred pieces of original glass, there is no way to make a qualified lens.

At this point, Chen Dali is still very confident in his craft.

"Doctor Chaozheng, I think this lens is just a piece of glass? This microscope can simply assemble a few pieces of glass together to see the so-called invisible microorganisms? ”

In the lecture hall, Hua Yunnei was a little confused and talked to the nest side beside him.

"There is something called a magnifying glass in the Gewu Academy of Guanshishan Academy, which I have heard of before. But that magnifying glass is said to only magnify things a few times, and this microscope should have some similarities with the principle of this magnifying glass, but it is very different. Otherwise, it would be impossible to see the microorganisms. ”

The nest did not doubt the authenticity of the microscope.

After all, Li Kuan dared to let people explain the principle of the microscope on such an occasion, and there seemed to be a sample of the microscope on the podium, so it was impossible to be so bold as to fake it there.

"Doctor Nest is you believing that you can see microorganisms with this microscope? Does this microorganism really exist? ”

Hua Yunnei is not proficient in surgery, and he does not recognize the term microbiology.

"Although many people in Chang'an laughed at the articles published in the journal Science, I think it is very likely that microbes actually exist. Why do you think that wind chills are so easily contagious to each other? Is it because there are microorganisms that play a role in the transmission? There is also the point of view of wound infection and wound disinfection mentioned in their previous article, if there is a microorganism that will make the wound inflamed, and then alcohol can kill this microorganism, then the principle of alcohol disinfection can be properly explained. ”

Although Chao Fang majored in internal medicine, he was also involved in surgery.

He naturally knew that the School of Medicine of Guanshishan Academy used alcohol to disinfect wounds and could effectively prevent wound infection.

"Unless I can see the so-called microbes through the microscope for a while, I still don't believe that there is anything in this world that the eye can't see."

Hua Yunnei does not hit the south wall and does not look back, and it is difficult to accept what Chen Dali is saying.

……

"I know that everyone must be very interested in the microscope that Chen Dali just mentioned, and there will be many microscope samples here for you to use. But before that, please listen to me a little bit more about microbes. ”

When Chen Dali finished his speech, Tong Zhou stepped onto the podium.

At this time, it is naturally not popular to applaud.

Therefore, in the lecture hall, except for the buzzing discussion in the audience, there was no other atmosphere of encouragement.

However, Tong Zhou didn't expect so many bigwigs in the lecture hall to say anything encouraging to him, and directly started his lecture according to the previous arrangement.

With the cooperation of the students of the Institute of Microbiology, the blackboard was constantly replaced on the podium.

Many pictures seen through the microscope are displayed in front of everyone.

These portraits were drawn by students who were proficient in painting based on information observed in the microscope.

No way, if you want a camera these days, it's impossible.

This is the only way to experience the charm of the lecture.

"This picture is based on the microorganisms in the water droplets observed by the microscope, don't you think it's incredible? Why are there so many microorganisms in the clear water droplets? Does this mean that we also have a lot of microbes in our stomachs? ”

On the podium, Tong Zhou slowly found his senses.

"I'm sorry to tell you that everyone's stomach is made up of many microorganisms. Of course, there is no need to be afraid, these microorganisms are not necessarily harmful, and some microorganisms may even play a role in assisting the digestion of physical objects. ”

It took Tong Zhou almost an hour to finish introducing his microbe-related content.

This time, there was a rare silence in the lecture hall.

Although Tong Zhou had published similar articles in Science magazine before, now he swears that he will be able to speak from the podium and let everyone observe microbes through a microscope for a while.

Even if everyone had doubts in their hearts, they didn't dare to raise them immediately.

Before attending this lecture, there was no problem with how everyone ridiculed the unreliability of microbial theory.

If you ridicule it again in this situation, you may be slapped in the face on the spot.

"Thank you, Your Majesty, thank you to the princess of Chu, thank you to all the ministers and all the gentlemen who participated in today's exchange meeting, after listening to the first two lectures, everyone must be eager to take a look at this microscope and see what microorganisms look like. Then for the next half hour, you can take turns to come up and watch these microscopes, and we have arranged special students to guide you on how to operate the microscope. ”

Li Kuan walked to the podium again and announced an exciting decision to everyone.

However, the number of microscopes on the stage was only twenty, and today there were more than 500 people attending the meeting.

Some people don't necessarily have the opportunity to see it in person today.

"Ayah, how's it going? Isn't this microscope as amazing as it was just said? ”

When the eldest grandson Wuji finished using the microscope and calmly let the next person use it, the eldest grandson Chong hurriedly stepped forward to ask.

There are a lot of bigwigs who came today, and Changsun Chong still didn't have the opportunity to try the microscope so soon.

In this case, basically no one needs to organize, and everyone will spontaneously decide who will try it first according to their status.

Of course, Li Shimin had a microscope presented by Li Kuan in the Xuanzheng Palace, but he didn't join in the fun with everyone.

"It seems that our decision to set up the Gewu Academy in Weishui Academy is correct. This microscope looks ordinary and doesn't have anything outstanding, but it can magnify things hundreds of times, allowing us to see things that we don't normally see. ”

The eldest grandson Wuji looked at Li Kuan, who was standing not far away and talking to the princess of Chu with a complicated face.

As soon as this academic exchange meeting of Guanshishan Academy was held, no one in Chang'an City dared to jump out and say that microorganisms did not exist.

Li Kuan invited so many bigwigs to attend today, and he also wanted to let these people endorse microscopes and microorganisms in disguise, right?

"So, this microscope and microbes are real."

Changsun Chong was a little disappointed, and even his voice became lower.

Although he already had a premonition when he listened to the lecture, now that he heard the confirmed news from his own ayali, the situation was a little different.

"The microbiology research institute of Guanshishan Academy has only been established for a long time, and we are not without the opportunity to surpass. This microscope is the key to studying microorganisms, and you will see if Guanshishan Academy sells this microscope in a while, if it does, then you can directly make the decision to buy a dozen or twenty units for Weishui Academy. ”

Now that it has been discovered that microorganisms do exist, what the eldest grandson Wuji is thinking about at this time is how to maximize his own interests.

Although it is not yet known what direct benefits studying microorganisms can bring to oneself.

But seeing that Guanshishan Academy was so active in promoting the research of microorganisms, the eldest grandson Wuji knew that Weishui Academy needed to follow up immediately.

Sometimes, you move slower than others, and it doesn't matter much, just catch up.

But if the vision is worse than others, then it will be troublesome.

……

"What? How much does a microscope cost a thousand dollars? Why don't you grab it? ”

In a corner of the lecture hall, Wang Fugui was in charge of the sales of microscopes with a smile.

Everything has already been made, so naturally more people need to use it.

Therefore, Li Kuan did not think of letting Guanshishan Academy monopolize the microscope.

However, during this time, so many people are splashing dirty water on Guanshishan Academy crookedly, and they always have to collect some interest to come back, right?

After today's exchange meeting, everyone has seen the extraordinary microscope.

But anyone who has some ideas in medical research can't help but buy a microscope.

"Eldest grandson Langjun, our microscope also has cheap ones. For example, if you have a magnification of 200 times, you only need 500 yuan. If you still think it's too expensive, we have cheaper ones too. No, this magnification of a hundred times only costs a hundred yuan. ”

Wang Fugui has also seen a lot of noble families now, besides, with Li Kuan's support, he is not afraid of being questioned by others about selling things expensively.

Dislike expensive?

You don't have to buy it.

This thing is not food, so the court will not care if you sell it expensively or not.

Besides. High-tech things, if the price is not high, how to reflect its forced style?

"Can this hundredfold microscope see microorganisms?"

Eldest Sun Chong asked with anger held back.

"Only these 400 times the microscope can see microorganisms, and a hundred times the nature will not work."

Wang Fugui has one thing to say, so naturally he will not lie about this kind of thing.

"So what's the use of me buying it?"

Changsun Chong felt a mouthful of blood and wanted to spit it out.

"It won't be useless. For example, if you want to see what your hair looks like, you can use a 100-fold microscope. There are also things that look very small to the naked eye, and you can see her specific appearance with this microscope. ”

Wang Fugui also made some preparations for today.

Therefore, when it comes to the function of the microscope, it is also the head.

"The microscope that can see microorganisms clearly, a thousand times, is too expensive. I buy ten, can it be cheaper? ”

Changsun Chong was very depressed, when did he actually bargain with others like a trader?

"I'm sorry, this microscope is priced at the same price, and there will be no counteroffer. You don't look at this microscope as simple, it's not simple at all, the lenses are very, very complicated to make, and the scrap rate is very high, and the yield is very low. If you don't buy it today, and someone else buys it first, even if you want to buy it again, you will have to wait a month for delivery. ”

Eldest Sun Chong: ......

"Shopkeeper Wang, I'll buy five! The kind that can see microorganisms. ”

Just when the eldest grandson was entangled, there were already people from Qujiang Academy next to him who began to place orders.

Everyone heard the conversation between Wang Fugui and Changsun Chong.

They don't think that their face can be bigger than that of Changsun Chong.

In this case, the production capacity of the microscope is tight, so if you don't hurry up, when will you wait?

"I want one too, the thousand-thousand-run kind."

"I just want a hundred-thousand."

"I want two thousand units."

Someone started, and someone immediately followed.

No one is stupid, this microscope is a unique business, unless you are not interested in it.

Otherwise, if you don't want to take this knife, you will have to suffer.

This feeling has left many people with a deep memory.

Indirectly, this has also fueled enthusiasm for new equipment.

Everyone thinks that one day they can get stuck with others like this.
