Future Star Kindergarten has just opened, so there is no big turmoil for the time being.

Although it aroused heated discussions among the nobles in the first few days, everyone gradually became accustomed to it.

However, Li Kuan discovered that Gewu Academy had actually brought him a surprise.

"Yan clan, this Tong Zhou, if I remember correctly, is a not-so-distinguished professor in the medical school, right?"

Li Kuan flipped through the article to be published in the latest issue of "Science" and read it with relish.

“When you observe various things through a magnifying glass designed jointly with the glass workshop, you will find many interesting things. For example, when you look at a smooth and continuous straight line that we usually draw with a quill pen under a magnifying glass, you will find that it is actually very smooth.

Rough, isn’t it surprising? These straight lines are actually discontinuous dotted lines composed of many small black dots!”

"Some women who love beauty always want their skin to be extremely smooth, but when you look at this smooth-looking skin under a magnifying glass, you will find that the pores under the skin are large and uneven, which is completely different from beautiful

It has nothing to do with it, you can even see some dark things in the skin obviously mixed in."

Li Kuan did not expect that the magnifying glass was not fully utilized in Gewu Academy, but was first developed in the medical school.

Of course, if this article was just an introduction to magnifying glasses, he wouldn't find it particularly strange.

After all, reading glasses and myopia glasses have been developed, and magnifying glasses themselves are not that difficult.

"These things that we usually take for granted show a different world under a magnifying glass. So, I was thinking that when we sutured the wound, we did not use alcohol to disinfect it, and the wound would most likely become inflamed.

If it becomes inflamed, it will most likely not be cured."

"Why is there less inflammation after disinfection with alcohol? Is there something we can't see on these wounds? Although it seems that nothing can be seen with the current magnifying glass. But we are bold

Hypothesis, if the power of this magnifying glass is ten times or a hundred times that of the current one, can you see something?"

"I think this result should be positive. There must be some very small things in this world that we can't usually see with our glasses. I think whether it is inflammation of a wound or food spoilage, we should look at these things

It’s the little things that don’t come that matter.”

When Li Kuan read this, he completely decided to add fire to this teaching called Tong Zhou, so as to raise everyone's understanding of the world to a higher level.

"Your Majesty, although this article has not been confirmed yet, several members of the review committee of "Science" think this article is very imaginative and may provide a new way of treating diseases for our medical school, so I am prepared

Put it in there for publication.”

Xu Jingzong saw Li Kuan reading the article written by Tong Zhou with such interest, and also made some explanations on the side.

"The new issue of Science will be officially published in five days, right?"

"Yes, it normally takes five days to publish."

Although I don’t know why Li Kuan asked this question, Xu Jingzong is obviously very familiar with these basic contents.

"In this case, you go and call Tong Zhou over. I have an idea to verify the 'little thing' mentioned in his article. When the time comes, I will revise this article and directly give the inferred 'little thing'

Once implemented, the sensation caused will definitely be different."

Li Kuan felt that in order for medicine to have a breakthrough development, things like bacteria and viruses must enter the vision of Guanshishan Academy Medical College, otherwise no matter how hard they try, they won't be able to achieve much success.

…

"I have met His Royal Highness the King of Chu."

Although Guanshishan Academy is not small, Li Kuan still needs to meet someone very quickly.

"Tong Zhou, I find this article of yours very interesting. Can you bring your magnifying glass with you?"

Li Kuan did not mince words with Tong Zhou and went directly to the topic.

"Yes, this is it."

Tong Zhou was slightly excited and took out a small wooden box from his arms.

It was obvious that he cherished this magnifying glass.

Because this magnifying glass is packed in a delicate sandalwood box and wrapped with a piece of woolen cloth to avoid damage.

"Approximately how many times can this magnifying glass magnify an object?"

Li Kuan took out the wooden frame from the box, with a magnifying glass in the middle, and turned it around curiously.

"Your Highness King Chu, this magnifying glass can magnify things about twenty times. It is the best lens currently ground by the glass workshop."

Li Kuan was a little disappointed after hearing this, but he thought it was normal.

A simple magnifying glass, even in later generations, can generally only do about thirty times, and if it is larger, it will have to be turned into a microscope.

Now that Tong Zhou can take out a magnifying glass with a magnifying glass of about 20 times, it is already a great achievement.

"Have you ever considered fixing the lens of this magnifying glass on a frame, and then using other lenses to see what is under this lens?"

Li Kuan has used a microscope after all, and the principles of a microscope are often tested, so he still has some impressions.

Now that medical schools are ready to study bacteria and viruses, the emergence of microscopes is also necessary.

Although he could also exchange a microscope directly from the system, the plastic material of those lens holders was not available in this era, and it would be quite troublesome to explain it at that time.

It would be better to redeem a technology yourself and directly guide Tong Zhou to study the microscope, which would be more reliable.

As for now, I just want to communicate with him first.

"I have never tried the method you mentioned, His Highness King Chu. I will go to the glass workshop when I get back and discuss it with Chen Dali to see if we can make this kind of magnifying glass."

"Yanzu, you can ask the academy to cooperate with the glass workshop to set up a special research institution to study how to make the magnifying glass more powerful. This is of great significance to the development of the medical school. For Gewu Academy,

Maybe it also has unique uses."

As a very common piece of equipment in scientific experiments, the microscope is naturally indispensable.

"Don't worry, Your Majesty, I will go to the glass workshop later to finalize this matter."

Xu Jingzong saw that Li Kuan seemed to be very interested in these things, so he was naturally prepared to deal with them as soon as possible.

"Going back to this article, Tong Zhou, why do you firmly believe that there are still some 'little things' in this world that cannot be directly seen by the human eye?"

Li Kuan pointed to the manuscript in his hand and waved it in front of Tong Zhou.

"Bold assumptions, careful verification. I remember what His Royal Highness King Chu said in the academy lecture. There are things in this world that our eyes cannot directly see. This is based on my research on wound inflammation and food decay.

Hypothetically, now I am working hard to confirm the existence of the 'little thing'."

Tong Zhou is a bit dull, but on the contrary, he makes people feel very stable.

"Then do you have any ideas now?"

"Not yet." Tong Zhou just finished speaking and quickly continued, "But I believe we will find an idea soon."

"If you don't have any ideas, I do have some ideas. Take food rot as an example. According to you, some small things should have fallen on the food and then multiplied there, eventually causing the food to rot. Then we won't

Can you design an experiment so that small things in the air cannot easily enter the food, and then leave it for a few days to see if it will rot?"

Li Kuan explained the experimental method step by step.

"But there is no way we can prevent small things in the air from entering the food? Even if it is sealed in a box, the food will still rot."

"That's because there are still 'little things' inside the sealed box."

"Then how can we make the 'little thing' not exist? Otherwise, there is no way to carry out this experiment."

When it came to specific academic issues, Tong Zhou no longer regarded Li Kuan as a prince.

The conversation between the two people was getting faster and faster, and Xu Jingzong on the side was slowly unable to understand.

"So, don't there be flasks in the medical school's laboratory? These flasks are all open. If they are used to hold food, they will definitely allow 'little things' to enter easily. I will draw another gooseneck bottle to allow this kind of

The mouth of the flask is curved like a gooseneck.

Then we fill both flasks with broth, and then use fire to heat the broth until it boils. According to my understanding, most living things cannot survive in a boiling state, so the '

The little thing must have been killed after being treated like this.

Then we put these two types of flasks in a warm room to see if they start to rot and deteriorate at the same time. If, I mean if, the broth in the gooseneck bottle has not changed after a few days

It's bad, and it hasn't gotten bad even after a month, so does that prove that there are 'little things' in the air that we can't see?"

In order to let Tong Zhou understand what he meant, Li Kuan was rarely verbose.

"Your Majesty, if the little things in the air can move on their own, then even if the broth in the gooseneck bottle goes bad, it doesn't prove that the 'little things' don't exist."

Tong Zhou said tangledly, "However, if the broth in the two flasks has deteriorated, it doesn't prove the existence of the 'little thing'."

"That's right, if the broth in both flasks has gone bad, then it neither means that the 'little thing' does not exist, nor does it mean that it exists. But if only the broth in the gooseneck bottle has not gone bad, then basically

It can be seen that there are unknown 'little things' in the air, and even in the water we drink and the food we eat, there are such invisible 'little things'."

Pasteur's gooseneck bottle test itself was not used to prove the existence of bacteria, but was used to prove that living things can only originate from living things, and non-living substances in nature can never spontaneously produce new life at any time.

However, Li Kuan felt that no matter how to prove the existence of the "little thing", it would be convincing.

Of course, the best way is to quickly produce the microscope and let everyone see what the "little thing" looks like.

As the saying goes, facts speak louder than words, then everything will no longer be so entangled.

"My lord is wise, this method is really good, I'm going to prepare for the test now."

After listening to what Li Kuan said, Tong Zhou stood there thinking for a while, then slapped his thigh and cheered loudly.

"Wait a minute, I already have some ideas for this goose-neck bottle. I will draw it directly, and then ask you Xu Canjun to send someone to the glass workshop to start firing the goose-neck bottle today."
