Into Unscientific

Although the nitroglycerin was given hastily, there was no other way, and there was not much time left for Xu Yun.

After all, angina pectoris caused by coronary heart disease is a sudden illness with uncertain onset time and intensity. It may only be chest tightness for a few seconds, but it may also lead to sudden myocardial infarction death.

It is now the end of 1850, and there is no mobile phone or WeChat to guarantee the first contact, and Darwin is not an employee of the school, so it is hard to say when the next meeting will be.

Under such circumstances, it was not easy for Xu Yun to slowly build up the relationship - anyway, he was the descendant of the mysterious Fat Fish, and he was also a student at Cambridge University, so his identity was relatively reliable.

Even if Darwin had doubts in his heart, he would not turn around and throw away the medicine he needed, at most he would not use it as a last resort.

Once Annie was in an extremely dangerous situation, and there was no medicine to treat her, he would naturally think of these nitroglycerin.

In his previous life, Xu Yun wrote a similar plot when he was writing a novel. As a result, a reader posted a comment: This practice is not advisable in reality. After nitroglycerin is in contact with air, a film will form, which will affect the efficacy of the medicine.

how to say

This approach will definitely affect the efficacy of the medicine, which is unavoidable.

But first, drug failure and film formation are irrelevant things.

Secondly, as long as it is tightly wrapped with cloth and not exposed to high temperature and light, the efficacy of the medicine will not be affected too much.

Nitroglycerin tablets do form a thin film with air, but that's because of the polyvinylpyrrolidone and has nothing to do with the nitroglycerin ingredients.

The reason why the efficacy of nitroglycerin decreases in the air is actually because of its instability, it will volatilize under high temperature and sunlight - the last three words are recommended to read the last three words several times.

That's why its bottle is brown.

As for cloth wrapped in nitroglycerin, this is a very primitive and effective way of preservation.

For example, William Merrill used cloth sheets for preservation at the beginning, because the sheet pressing technology was not stable at that time, and nitroglycerin had a certain risk of explosion.

It’s just that under the modern background, our technology and preservation conditions are already sufficient, so the doctor will order it to be sealed and preserved in one step, and there are not many patients who can understand the ingredients such as polyvinylpyrrolidone, which will waste time and money. energy.

Still the same sentence, maybe this practice will lose some of the efficacy of the medicine, but in 1850, Xu Yun did not have the ability to do it honestly according to the procedures of later generations-he only had such a bottle on him, and it was impossible to take this medicine. A bottle of nitroglycerin is given to Darwin, isn't it?

Loss of drug efficacy by 10% or 20%, sometimes the impact is not that big-not to mention that the effect of nitroglycerin lozenges is to relax vascular smooth muscle, and the released nitric oxide is actually higher than the model dose.

As long as it does not volatilize more than 30%, it will be effective for angina pectoris.

Hey, this is water. Have you learned 700 words of popular science?

Keke, let's get back to business.

After handing over the nitroglycerin to Darwin, Xu Yun temporarily separated from Lao Da, ending this unexpected meeting.

He checked some information later, and guessing that it was almost time, he went to the first floor to find Mai, and the two returned to the dormitory together.

In the next four days, the two of them went back and forth to and from the library with blank eyes again and again, Mai Mai previewed the text, and Xu Yun had a more detailed understanding of the current timeline.

There are gains and disappointments.

It goes without saying that Xu Yun has basically mastered the changed European timeline.

Disappointment is.

Perhaps because the means of shipping are still underdeveloped, there are not many oriental documents that can be consulted in the Cambridge library. Even if there are, most of them are introductions from India or neon, and there are very few books about China.

You know, since 1707, the Cambridge Library can be regarded as one of the most complete libraries in the UK.

Book collections that don't even exist here, probably can't be found in the whole of England.

However, although there are not many reference books, Xu Yun is sure of one thing: that is, the local history has hardly changed.

For example, the Northern Song Dynasty was still flattened by a wave in 1126. Zhu Yuanzhang rose a hundred years later, the Ming Dynasty reopened the Great Song Dynasty, Li Zicheng broke through Yanjing in 1644, and Chongzhen died for the country by hanging the southeast branch on the old crooked neck tree.

Originally, Xu Yun thought that the reason why the mainland could not survive the increase in Western productivity might have something to do with what he did in the old Su dungeon—although it could not be the original 1100 dungeon timeline, but Probably in some fields there is a certain association similar to easter eggs.

For example, breakthroughs in weapons or metal smelting have strengthened the local defense to a certain extent, and so on.

But now it seems that there is no connection between the mainland and itself in this world line, and the reason that the mainland can last so long is purely due to other reasons.

There are good and bad conclusions to this conclusion.

The good thing is that you don't have to worry about the divine punishment of historical nihilism, and you can live your little life in peace and security.

The bad thing is that there are no countermeasures in the local area, and that painful history of modern humiliation is doomed to be inevitable.

Three days later, Avelyn delivered the schedule to Xu Yun and Mai Mai as promised.

Another day passed.

Cambridge University officially opens.

The number of students admitted to Cambridge in the class of 1850 was about 200 more than before, and the number of students enrolled in a single class was around 700, which is not a small increase.

According to Thomson, the UK is now preparing to make a big splash in the Far East, so it has conducted a round of enrollment expansion for fresh graduates and is preparing to cultivate more reserve talents.

In fact, Cambridge University is not bad, and Oxford this year is even more outrageous-it has recruited more than 600 people in one breath. (This is the real situation that happened in 1840, and it was used until 1850)

Among the 700 people recruited by Cambridge University, the number of graduate students is about 220.

At the same time, because some colleges do not offer postgraduate courses, after subdivision, for each college with postgraduate courses, the number of newly recruited graduate students is about 25-35.

The number of postgraduate students assigned to Trinity College was neither too many nor too few, and there were about 29 of them.

As for undergraduate freshmen, there are more, and 67 people have been allocated.

However, unlike many schools in later generations, the entrance ceremony of Cambridge University was not held uniformly by the whole school, but by each college. It is not difficult to see that the degree of autonomy of each college is similar to that of Jiangsu in later generations.

So by coincidence, the entrance ceremony of Xu Yun and Mai Mai happened to be held in the same classroom.

In the early morning of this day, Xu Yun and Mai Mai woke up early.

"Mr. Luo Feng."

After washing, Mai Mai took out a suit from the suitcase, dressed neatly, straightened the cuffs of the cuffs, checked it up and down, and said to Xu Yun:

"Does this suit fit me?"

Xu Yun stroked his chin and looked at it for a moment, then nodded:

"Not bad, quite handsome, it shouldn't be a big problem to talk about a girlfriend."

Mai Jian said that she scratched her thinning hair shyly, and smiled:

"This is my dad's lawyer's suit that just retired—actually, according to my original idea, I wanted to re-customize a suit with the scholarship prepaid by the college."

"However, my dad said that his suit won many lawsuits with him and would bring good luck to others, so he gave it to me."

Hearing this, Xu Yun couldn't help but see a picture of a loving father and a filial son, and nodded approvingly:

"What a good father, by the way, what if he doesn't have a suit in the future?"

The movements of Mai Mai's hands paused, she glanced at Xu Yun in surprise, and said:

"Who said he didn't have any suits? He used my scholarship to order a new one."

Xu Yun: "."

Something seems wrong?

Then Xiaomai took out the square-toed leather shoes that Lao Mai made for him, and rearranged his hairstyle.

If he didn't speak that strong Scottish accent, he would still look seventy-third as handsome as the readers.

Compared with Mai Mai's solemnity, Xu Yun's is much simpler—whatever clothes he wore when he time traveled, he is dressed in what he is now.

After packing up the outfit.

Xu Yun and Mai left the dormitory together.

"perfomie lecture theater"

Xu Yun and Mai Mai held the necessary "Bible" of Trinity College in one hand, and in the other hand held the classroom information given by Avelyn to search for it according to the map. They co-authored the memory left by the exchange student year, and the two quickly found it. This lecture theater on Hamill Avenue.

The perfomie lecture hall of Trinity College ranks first in the entire Cambridge University and can accommodate about 500 people.

In his previous life, Xu Yun had taught several times in the perfomie classroom. At that time, this lecture theater was equipped with modern equipment, very advanced, and even VR, AR equipment and a lifting platform on the ground.

Therefore, Xu Yun always thought that this classroom was built in modern times, but he did not expect that it had already existed in 1850.

When Xu Yun and Mai Mai came to the classroom, there were four student union cadres with armbands checking their student cards outside the door.

The four cadres, two men and two women, had different college badges on their chests, and Xu Yun only recognized two of them:

The tallest boy went to Trinity College, and the school badge of his own college must be unforgettable.

Another girl wears the emblem of Peter College on her chest.

Xu Yun recognized this academy emblem mainly because of its high degree of recognition:

It was a shield icon with an all-red background, eight crowns surrounded the inside, and five yellow vertical strips in the middle. With a fort, it was almost like Arsenal's team emblem.

As for the remaining two pieces, Xu Yun is not too sure. His awareness of the courtyard emblem is indeed limited.

After arriving in front of the three of them, Mai Mai and Xu Yun obediently handed over their student cards.

The tall boy with the emblem of Trinity College took the student card, glanced at the roster, and suddenly raised his eyebrows:

"James Clerk Maxwell, are you the fee reduction student brought back by Thomson?"

Mai Mai nodded and stretched out her hand:

"Senior, I am Maxwell."

The tall boy's gaze rested on Mai Mai's outstretched hand for a few seconds, and finally he shook hands with him:

"Frederick Agar Ellis, a third-year graduate student in the mathematics department of Trinity College, maybe we will meet again in the future."

Then he glanced at Xu Yun again, an inexplicable look flashed in his eyes, and said:

"Two students, you can enter the classroom now, and your seats should not exceed the first six rows. I wish you a happy stay in Cambridge University."

Mai Mai opened his mouth, as if he wanted to say something else, but Xu Yun pulled him back, and bowed slightly to Ellis:

"Please take care of me from now on, Ellis-senpai."

After speaking, he dragged Mai into the classroom.

There are about forty people sitting in the classroom at this time, discussing some content in twos and threes. It seems that the professor and the college leaders have not arrived yet, and Stokes has disappeared, but the seat in the first row has been reserved. up.

He saw Mai Mai and Xu Yun entering.

Many people subconsciously turned their heads to look at the two, wanting to see if they were handsome women or acquaintances.

Ever since.

Swish——

Xu Yun instantly felt a lot of eyes land on him, and he could faintly hear a few cold snorts in his ears.

Xu Yun: "."

no way.

The oriental faces are still too conspicuous.

Oriental + a Scottish blond boy = back door + Fei Jiansheng, this formula has almost spread throughout the University of Cambridge.

Then he took Mai Mai to find a relatively rear seat and sat down, intending to wait for the leaders to arrive.

As a result, as soon as he was seated, Mai Mai seemed to hold back for a long time, and said to Xu Yun impatiently:

"Mr. Luo Feng, why do I feel that Senior Ellis's attitude seems a bit strange?"

In the past few days, the size of wheat can be considered a celebrity. On the way to the library or to eat, I often met Cambridge students who were surprised when they heard their names.

Some of these people are friendly, some are skeptical, and some are jealous.

all in all.

Wheat can clearly judge whether the other party's attitude towards him is good or bad from the words and expressions of these people.

But only the Ellis he met just now gave Xiaomai an indescribable meaning.

It's definitely not friendly, but hostility doesn't seem to be that extreme.

Thinking of the man's half-smile expression, Xiaomai felt a chill in the back of his head, as if someone had put a cold palm on his neck.

Then Xu Yun raised his eyelids and glanced at him, withdrew his warmed palm from his neck, and said meaningfully:

"Why, didn't you find out?"

Mai Mai blinked, and a question mark appeared on her face:

"Discover? Discover what?"

Xu Yun nudged towards the entrance with his chin, reminding:

"Graduate student in the Department of Mathematics, third-year qualifications, and the mention of Mr. Thomson, haven't you realized anything?"

Mai was taken aback for a moment.

This Scottish youth is honest and honest, but it doesn't mean he has an elm head, so he quickly widened his eyes:

"No way, Mr. Luo Feng, you mean."

Xu Yun nodded affirmatively and said:

"That's right, he must be one of Mr. Thomson's contenders for the president of the Student Union!"

At the same time, the second half of Mai Mai's sentence also spread over:

".You mean that senior Ellis likes Mr. Thomson, who is in the same grade, and got jealous when he saw him go to Ireland to pick me up?"

After a while.

The two of them suddenly widened their eyes and narrowed their eyes: ".?"

Note:

I didn't want to make up my own names, so I checked the alumni list of Trinity College, Cambridge University in 1850, and I checked the alumni of Trinity College, Oxford University for an hour.

A screenshot of the alumni page is attached to the easter egg chapter. I can guarantee that everyone who appears is a real person in history. For the sake of being so real, give me a monthly ticket.

This month's monthly pass is really very important. I can't really say clearly about some issues related to the direction of our book, but it is much, much more important than previous months.
