In Berlin in September, the weather is already starting to get cooler. \\

After a long vacation, the campus of the University of Berlin is once again bustling with activity. Not only are German students returning to campus, but so are international students from other countries. Of course, international students like John from across the ocean never left.

Classrooms are once again full of life.

“…… In view of the results of the above research, and based on a certain amount of speculation, Mr. Pasteur completed a great project twenty years ago. Many of you may have heard of it, and that is the gooseneck flask ......"

On the podium of a trapezoidal classroom, Associate Professor Fogel spoke to dozens of curious second-year students about the famous Shiyàn from twenty years ago. With the wave of his right hand, a rough solid device appeared on the blackboard with three strokes and two strokes. In this era, most of the teachers of medical schools have quite good sketching skills, especially some anatomists are proficient in this way. John is also secretly glad that he put a lot of effort into this, otherwise if he wants to be a teacher or write a book in the future, he will be completely blind without this skill!

Most of the students in the audience also listened attentively.

For people who do not communicate well in this era, even though Pasteur's reality has been completed for nearly twenty years, it is still so new to them. In Associate Professor Fogel's speech-filled narration, everyone seems to have seen the magical sight of the gooseneck flask Shiyàn - the broth that has been left for several years is still clear and transparent, completely subverting people's common sense!

John was the only one in the last row who was not interested, and his mind had already flown to Java.

These things from more than 100 years ago will be very interesting to listen to at first, after all, most of them will listen directly to the final theory in later generations, and rarely pay attention to the current process, and it is very good to listen to the story. But when he listened to and watched too much, it gradually became boring. Some simple theories were told over and over again, giving John the feeling of going back to elementary school after college. This is because the German medical schools now talk about this, and if they stay in the United States to study at the university, I am afraid that they will not even have to listen to these things.

"Mr. Huntelaar!"

Just as John was staring at him, Associate Professor Fogel on the stage suddenly frowned and called his name: "Can you talk about your understanding of the gooseneck flask...... Mr. Huntelaar! ”

In the last sentence, Associate Professor Fogel raised his voice and tone a lot more.

"Uh......"

Under the gaze of many classmates, John was slightly stunned, and then stood up a little helpless. Just now, he was so focused that he didn't even hear Associate Professor Fogel's question clearly, and he felt embarrassed for a while.

"Mr. Huntelaar, please talk about your understanding of the gooseneck flask!"

Shaking his head with some hatred, Associate Professor Fogel repeated the question he had just asked.

"Understood."

After hearing the question clearly this time, John's heart was suddenly relieved, but he still bowed slightly apologetically and said, "I'm very sorry sir, I was a little distracted just now...... Not next time. ”

"Oh?"

After listening to John's apology, Associate Professor Fogel remained silent and just made a gesture of please.

Fogel was unfamiliar with Huntelaar, an American student, who in fact taught these second-year medical students. Of course, he put a lot of thought into it before class, and the first lecture at the beginning of the lecture proposed the gooseneck flask real yàn because this real yàn is more interesting and can arouse the interest of the students. But I didn't expect a student to be so inattentive in the first class, how could he not be angry?

It's definitely going to give you a dismount!

Feeling Associate Professor Fogel's knife-like eyes, John secretly smiled bitterly, did not dare to slack off, and hurriedly said aloud: "Sir, Mr. Pasteur's gooseneck flask has ostensibly confirmed that bacteria reproduce by themselves, not naturally generated, which overturns the natural growth ** and gives birth to the theory of biogenesis. But from the point of view of a medical student, I think the most important thing for us is the indicative significance for the medical field, such as infectious diseases, embalming and surgical disinfection techniques, etc......"

"Buzz ......"

As soon as John's voice fell, there was a slight commotion in the classroom.

The classrooms are all second-year students of the University of Berlin Medical School, most of them have just heard of this reality, and few people think about anything, not to mention that it is now the 19th century, and the truth that ordinary people in later generations understand is still "profound" at this time.

So when you hear John say a series of "technical words", many people are unaware.

Professor Fogel's pupils also shrank slightly, and his gaze at John suddenly changed, he frowned, and said in a deep voice, "Mr. Huntelaar, can you elaborate on your opinion?" ”

"Yes, sir!"

John, of course, did not flinch, and after a slight smile, continued: "First of all, in terms of infectious diseases, everyone must know that in addition to Mr. Pasteur, Mr. Robert Koch of the Royal Health Service is also an authority in the field of bacteriology. He had identified Bacillus anthracis a few years earlier, and had completed in vitro culture, and then understood the methods of bacterial staining and animal rubber dish culture,6 and continued to develop the bacteria that cause tuberculosis and cholera, and proposed the relevant Koch principle......"

As he listened to John's eloquent talk, Professor Fogel kept nodding his head.

As a loyal follower of Koch, Professor Fogel naturally knew the German medical giant very well, and John was talking about some of his most important achievements.

Slowly, Professor Fogel's gaze at John softened.

Although what John said was out of the scope of the gooseneck flask, and it was not the same as what he had originally said, he would certainly feel relieved as a teacher to hear that there were students who were so diligent and learned so much in advance.

“…… As a corollary, I think that many of the world's diseases may be caused by bacteria or other tiny organisms, and the exhibition of bacteriology may provide doctors with solutions to these diseases! ”

John slowly realized that his answer was a little bit of a donkey's lips, and he didn't dare to say too much, but only said some of the fur in general terms that he had so far.

"Not bad!"

After listening to John's narration, Fogel couldn't help but applaud lightly, smiled and nodded repeatedly: "That's a very good point, it seems that you have a pretty good understanding of bacteriology...... Mr. Huntelaar, I heard you mention surgical sterilization techniques, are you interested in surgery? ”

"Of course!"

John nodded heavily and smiled, "Sir, I visited Mr. Liszt last year, and I became interested in surgery. And I chose to enroll in the University of Berlin Medical School because I wanted to be a good surgeon! ”

"Oh? Why do you want to become a surgeon? ”

With a frown, Associate Professor Fogel asked with some puzzlement. Although the status of European surgeons is now significantly higher than before, it is still inferior to that of traditional physicians, so Fogel was slightly puzzled by John's crisp answer.

"Because I think surgery has a future!"

After a moment's hesitation, John decided to say something more. Originally, he had planned to start making a name for himself after completing his understanding of the "modern" knowledge system, and he certainly did not retreat at this time.

But even so, John had to carefully consider what he said, and then continued: "Sir, I think that as far as the current technical exhibition is concerned, the three problems that limit the surgical exhibition will soon find solutions, so there is a lot of room for the future exhibition of surgery......
