"Gotcha! Get! ”

The low knock on the door was particularly clear in the quiet hallway.

But after waiting for a while, John didn't get the response he wanted, and the room was silent. Frowning slightly, he raised his right hand again.

"Sir, who are you looking for?"

At this moment, a voice suddenly sounded from behind John, making his hands tremble. It was class time, and the corridor was dim and quiet, and he couldn't help but be startled by the sudden sound.

Turning to look at the somewhat guarded young white man in front of him, John smiled and said, "Hello sir, I'm looking for Wilm. Conrad. Mr. Röntgenium. ”

"The new Professor Roentgen?"

The young white man's brow furrowed, and he looked John up and down.

John was a little puzzled by others, and couldn't help but ask, "Sir, is there anything strange about me?" ”

"Oh, nothing."

Waving his hand, the young white man said angrily, "If you are looking for Professor Roentgen, it is really not the right time, he should be in the laboratory now...... If you're willing to wait, he'll be back by noon. ”

Without waiting for John's response, the young white man turned around and left.

"There's something wrong with this guy, right?"

Opening his mouth, John looked stunned.

After looking around, he couldn't find a second living person, so John had no choice but to walk out of the building and wait patiently in the shade of the tree at the door.

This year is a very important year for the German physics community. With the official opening of the National Institute of Physics and Technology in Berlin, Helmholtz, a leading figure in the field of physics, stepped down from his post as professor of physics at the University of Berlin to become the first director of the institute.

This person is the experimental physicist Kong Tuo.

As a result, the University of Würzburg lost its physics professor. Fortunately, there has always been an equally outstanding experimental physicist by his side, and he successfully took over the position of Kongtuo.

This person is Roentgen.

Speaking of Roentgen, most Chinese in later generations may not be too familiar with it, including the most important achievement in his life, Roentgen Ray, I am afraid that not too many people will know. But when it comes to X-rays. Or go to the hospital to "take a film", I'm afraid most people know what's going on.

Roentgen rays, that is, X-rays.

When he wanted to study the history of medicine on a whim, John had always been convinced that Roentgen was one of the most important figures who changed the course of medicine. Although he was a physicist, Roentgen and Liszt were in the same position in his eyes as Pasteur and Koch. This may be a bit of a subjective judgment, but it also speaks volumes about the importance of the Roentgen ray.

For the first time, this miraculous ray allows people to observe the situation inside the tissue non-invasively.

Although after Helmholtz invented the ophthalmoscope. Examination tools such as laryngoscopy and cystoscopy were also invented in the second half of the 19th century, but in the final analysis, they only examined the condition of human body cavities, but the appearance of X-rays allowed them to directly observe a deeper layer, such as muscles, and bones, which is self-evident for diagnosing diseases.

On the other hand, the advent of X-rays has also brought patients from their homes to hospitals.

Traditional diagnostic tools are nothing more than stethoscopes, thermometers, and blood pressure monitors. These simple, convenient tools are very easy to carry around and can be taken to the patient's home in a small case. But with the advent of X-ray machines. Such large equipment is not easy to use, so many times those distinguished patients have to come to the hospital in person to seek help from the current diagnostic methods.

Until 100 years later, X-rays were one of the six major imaging methods in medicine.

John asked his fiancée, Anna, to help him find out about Roentgen, so that he would naturally work with the physicist, if all went according to history. Röntgen would have discovered X-rays by accident in 1895 after he became rector of the University of Würzburg, but now Johann is staying in Würzburg in order to be able to detect them early......

……

It was originally a somewhat cold campus. It gradually became lively.

John, who was a little bored, hurriedly took out his pocket watch and saw that it was already noon, and at this time, a middle-aged man in his forties was holding a few books and hurriedly walked to his location. After seeing the middle-aged man's appearance clearly, John's heart suddenly moved. The middle-aged man is about medium height, and his figure is very ordinary, but the beard that almost hangs down to his chest is particularly conspicuous, and the resolute eyes under the high raised eyebrow bones also make John feel very familiar.

"Thank God!"

Overjoyed, John couldn't help but thank the God he had never believed in.

The welfare of the traverser has brought her too many benefits, as long as he has studied in his previous life, and even as long as he has seen things, he can basically clearly appear in his mind, such as the middle-aged man in front of him, and soon overlapped with the image in John's mind.

After recognizing the identity of the person who came, John did not hesitate, took two steps forward to block the path of the middle-aged man, and asked respectfully, "Excuse me, are you Professor Röntgen?" ”

"Yes, I am."

The conditioned reflex was general, and the middle-aged man immediately stopped, but the eyes that looked at John quickly became a little puzzled: "May I ask if you are ......?"

"It's an honor to meet you, Professor Roentgen!"

A happy smile immediately appeared on John's face, and he stretched out his right hand and said, "I'm John, an associate professor at the University of Berlin?" Huntelaar, please forgive me for taking the liberty of visiting. ”

"University of Berlin?"

Röntgen's eyes lit up, and he quickly put the book in his hand in the armpit, and enthusiastically stretched out his right hand: "It's a pleasure to meet you, Mr. Huntelaar." ”

That's why John pulled out his name as an associate professor at the University of Berlin again, and it was hard to imagine that Röntgen would look at him directly if he had told him that he was an American and a surgeon. Maybe because of busy work or other things, you just throw yourself aside. But with his title as an associate professor at the University of Berlin and the factor of Contortion, Roentgen may have to pay attention to it.

In those years, the University of Berlin was the center of German scholarship.

Otherwise, after Helmholtz left the University of Berlin, Konther would not have taken over his position, and Roentgen, who had been with him for more than ten years, was offered the opportunity to be a professor of physics in Würzburg. So as soon as he heard that Johann was from the University of Berlin, Röntgen subconsciously thought that the other party was an associate professor of physics, and that he knew Conto.

So although he was a little puzzled, Röntgen immediately invited John to his office.

After coming to the office and sitting down, Röntgen quickly asked his doubts: "Mr. Huntelaar, may I ask you what is the matter with me?" Did Mr. Condo commission you? ”

"No, no, I don't have anything to do with Mr. Conto."

When he got to the office, there was no need for John to continue to hide anything, and he shook his head with a smile and said, "Actually, I'm not a physicist, but a physician...... Well, to be precise, I used to be an associate professor at the Faculty of Medicine at the University of Berlin! ”

"Doctor? Faculty of Medicine at the University of Berlin? Once? ”

After hearing this answer, Röntgen was dumbfounded! (To be continued......)
