"I'm sorry, Mr. Huntelaar."

Staring at a pair of eyes, Röntgen asked with a blank face: "I think I didn't seem to understand just now, you mean that you stumbled upon a strange physical phenomenon and couldn't figure out what's going on, right?" ”

"Yes, sir."

Smiling slightly, John nodded earnestly.

Accidentally discovering a strange physical phenomenon or something, of course, John is talking nonsense, he just wants to "retell" the process of Roentgen's discovery of X-rays to the client, the purpose is naturally to hope that the other party can discover X-rays seven years in advance, and then contribute to his medical career.

Röntgen was stunned for a moment, and his gaze at John became more and more strange.

But without waiting for the other party to ask anything, John explained with a smile: "Professor Röntgen, when I was a student at the University of Berlin, I was very interested in physics, especially cathode rays, and I had conducted many experiments in the laboratory. After returning to the United States last year, I did not give up this interest in my spare time, and I have been researching it intermittently, and I also made a few Crookes cathode ray tubes for this purpose, and then I discovered this strange phenomenon by chance! ”

"Hmm......"

Professor Röntgen raised his eyebrows when he heard this, and his gaze at John softened considerably.

At first, when he heard John's identity, he thought that the other party was joking with him, but now listening to the other party's sincere tone, it seems that it is not the case.

And......

It seems that it is not impossible for a surgeon to study cathode rays.

Didn't Helmholtz, a giant of German physics in the second half of the 19th century and now a leading figure in science, first obtain a doctorate in medicine? After doing well in physiology, he turned to the law of conservation of energy, and then to physics. He achieved even higher achievements and worked his way up to the positions of Rector of the University of Berlin and Director of the State Institute of Physics and Technology. And in addition to these two directions, Helmholtz also has outstanding achievements in psychology, mathematics, etc......

That's right, scientists are so good these days!

This is of course also related to the characteristics of the times, such as Helmholtz, which happened to be in the early stage of the explosive development of science and technology in the 19th century. Both medicine and physics are quite "simple", which can make him so beautiful in so many fields. If it were placed more than a hundred years later, it would take ten or eight years just to get a doctorate, and the huge amount of knowledge would not allow him to be proficient in all fields of medicine......

While Röntgen was pondering these things, John took out his pocket watch and looked at it, and then said with a smile: "Professor Röntgen, you see it's lunch time, and I happened to have an appointment with Mr. Stavto, a professor of surgery at your university, could you please have lunch with you?" ”

"Professor Stavto?"

After hearing the name. Röntgen's heart moved.

Although he never paid much attention to medicine, Professor Roentgen knew about it and met several times. Since the other party knew Professor Stave, he should not be a liar or a prank, so for a while Röntgen became interested in the strange phenomenon that John was talking about.

After hesitating for a moment, Röntgen nodded and said, "Well, Mr. Huntelaar, it's a great honor to have lunch with two medical professors!" ”

Heard Röntgen promise to come down. John laughed.

It wasn't nonsense that he knew Professor Stavto, in fact the two had met before. There were also several letters to discuss the issues of surgical sterilization, local anesthesia and appendicitis surgery. The reason why he wrote a letter to the professor of surgery before he left New York was that at this time, after all, with the testimony of a professor at this university, Roentgen must have paid more attention to it, right?

Thinking of this, John immediately stood up and warmly invited, "Professor Roentgen, the appointed time is almost up." We'd better go now......"

……

Three days later, Johann got on the train out of Würzburg again.

For the past three days, he has spent most of his time in medical school, giving a lecture and then having a broad and lively discussion with the surgeons. One of the nights. In Röntgenium's laboratory, he "recounted" the physicist's great discoveries seven years later.

Sure enough, Professor Röntgenium's interest was thoroughly aroused by him.

Unfortunately, because Roentgenium was very busy with his work at the moment, and had reached a critical point, there was no way to carry out John's so-called experiment immediately. However, the physics professor also gave assurances that the experiment would be completed within the next month, and informed him of the specific results.

With this guarantee, it is enough.

After getting the results he wanted, Johann got on the train and rushed to Berlin, the capital of Germany.

A month is not a long time, John will stay in Europe for nearly half a year at the longest, so he can naturally wait patiently for the results of the other party, and even have time to further improve it. You must know that the structure of the early X-ray machine is very simple, and the gas-containing cold cathode ion X-ray tube with very low efficiency is extremely simple, with low efficiency, weak penetration, and low imaging clarity. What's more, this kind of X-ray machine often takes dozens of minutes to take a picture!

Exposed to the radiation for dozens of minutes, the patients dare not dare!

Not to mention the damage of radioactivity these days, no one knows, and even the radioactivity itself has not yet been discovered by scientists, but John knows very well how powerful they are!

So after Roentgen discovered the X-ray, John had to find ways to increase its imaging quality, shorten the imaging time, and reduce the harm to people. It's not that it's not very difficult, at least John knows the tungsten lamp X-ray tube, the filter grid and the cadmium tungstate phosphor screen, and even knows the general principle of the bifocal X-ray tube, and then he can leave it to the physicists to study. Although these things only appeared ten or even thirty years later, they are not particularly advanced in terms of physical principles, and I believe that it will not take too long to invest a large amount of money......

"Woo! Woo! ……”

With the high-pitched whistle of the train, it slowly drove into the Berlin train station.

Standing up from the bed in the box, John's heart thumped faster as he peered out the window.

Berlin, he finally came again.

It's only been a little over a year since I left, but everything in Berlin seems like it happened just yesterday: the University of Berlin, Charlotte Hospital, Heinz Medical Devices, Heinz Pharmaceuticals and, of course, Anna? Brister ......

Looking at the slowly retreating platform, John was full of anticipation.

Before leaving Würzburg, John sent a telegram to the Brister family, informing them of the approximate time of his arrival, presumably they had already sent someone to pick him up, right?

Who could it be?

Chamberlain? Coachman? Or some servant of the Brister family? Or is it ......

Slowly, the train stopped on the platform. With a chaotic thought flashing in his heart, John and Henry, who had already picked up all the salutes, walked out of the carriage with the crowd.

"Sizzle......"

Stepping out of the relatively stuffy carriage, John took a long breath of fresh air, and the whole person felt much more comfortable. For those who haven't been on a 19th-century train, it's hard to imagine what it would be like to be in it for hours or even a dozen hours: bumpy, dreary, and forever so long and unbearable. Even if John was in the best carriage, it still didn't make him more comfortable. From his arrival at the port in France to the present, John misses the days when he traveled in the Northern Lights, even if he had to deal with the unbearable problems of waking up early every day.

After a brief moment of relaxation, John and Henry immediately walked out of the station.

In the midst of the crowd, John looked around at the exit as he walked, looking for his familiar faces. However, relatively speaking, his height of 1.9 meters was more conspicuous in the crowd, and soon a voice came from afar: "Mr. Huntelaar, we are here!" "Huh?"

Vaguely hearing his name, John immediately turned his head to look.

A man in his thirties was tiptoeing loudly, was it the Brister housekeeper or the coachman or something? John couldn't remember it clearly, but at this time he didn't have the heart to recall this inconsequential question, because beside this man, a slender figure was looking at him with joy on his face.

"I'm here!"

A happy smile instantly bloomed on John's face, and he couldn't care about Henry, who was carrying a lot of things behind him, and rushed quickly in the direction of the figure...... (To be continued......)
