Chapter 277 Summer Vacation

After finalizing the plan, Zhang Xingjiu immediately made a precise timetable. He didn't need to be too far ahead of his competitors. He just needed to get the results out one or two months ahead of them and then use the paper to establish indisputable evidence.

According to this schedule, the main task this year, 1897, was to invent the cathode ray tube and, based on the results of the last blackbody radiation experiment, continue to conduct new experiments to improve the existing Wien formula.

Wien's formula actually has great potential to be tapped. Later, Rayleigh, Jeans and Planck successively improved this formula, and finally Planck came to the correct conclusion, which is also an achievement worthy of winning the Nobel Prize.

Since he was going to copy, he didn't mind copying more. Zhang Xingjiu planned to come up with their formulas before Rayleigh and Jeans, and then come up with the final formula before Planck, so that he would have five Nobel Prize achievements in his hands.

In the future, no matter who wants to study blackbody radiation, they cannot avoid these formulas. Unless the Royal Swedish Academy of Sciences does not intend to award the Nobel Prize for research in the field of blackbody radiation, it will have to award one to itself first before it can be the turn of others. This is the status of the founder of a certain branch field.

Now Zhang Xingjiu no longer has to attend classes every day like other students. Professor Lippmann recognized his abilities and gave him a lot of freedom. All Zhang Xingjiu has to do is pass the final exam, which is not difficult for Zhang Xingjiu at all.

Zhang Xingjiu was at his own disposal for the rest of his time. When he wanted to do experiments, the Sorbonne University gave him the greatest support. They provided him with money, equipment and people. Many students who had completed their undergraduate studies wanted to do experiments with him. As long as they could have their names listed in the paper, even as the third or fourth author, it would be of great help to them in obtaining their doctoral degrees.

He wanted to write a paper, so Lippmann arranged for people to help him collect information and test data.

If he wants to take a rest, he just needs to tell him. Even if he wants to go on vacation nearby, the school will not interfere. The school will arrange for a few students or staff to help him with transportation, accommodation and other trivial matters. He just needs to relax and feel at ease.

Lippmann and others had realized that Zhang Xingjiu was an absolute genius who could bring supreme honor to the Sorbonne University. Perhaps the school could use his talent to become a European physics research center. With such a temptation in front of them, which school leaders and scholars could resist it? What was the point of providing a little convenience?

Some people even came to find Zhang Xingjiu and persuaded him to join the French citizenship. As long as Zhang Xingjiu agreed, they would immediately take care of the rest for him.

Although they were all students of the Sorbonne University, the identities of Chinese students and French students were very different. They even offered the Nobel Prize to tempt Zhang Xingjiu.

Nobel settled in Paris in 1873. Although he was forced to leave in 1890 due to persecution and moved to San Marco, Italy, over the past 18 years, many French people became friends with Nobel and his family members.

Now that Nobel has passed away, his influence remains. These people can still use their influence to strive for the Nobel Prize for Zhang Xingjiu. If Zhang Xingjiu is willing to obtain French citizenship, they will help him make it happen.

Zhang Xingjiu believed in what they could do. Becquerel, the Curies and Lippmann were able to win the award, and perhaps these people also played a certain role. However, he would never become a French citizen. This was a matter of principle and was not negotiable.

After the new semester began, Zhang Xingjiu immediately started a new experiment. He divided the people assigned to him by Lippmann into two groups. One group continued to conduct blackbody radiation experiments and collected as much valid data as possible to modify and improve Wien's formula.

Another group tried to make a cathode ray tube based on his plan, and German physicist Karl Ferdinand Braun completed this great invention that year.

You may feel unfamiliar with the cathode ray tube. If we change the name to CRT, commonly known as picture tube, everyone will understand that this thing is very useful. It is an important component of television, radar and electron microscope, so it cannot be made too quickly.

Zhang Xingjiu told the team members that the Germans were also conducting research in this area. These French students immediately became excited and wanted to stay in the laboratory 24 hours a day so that they could invent the cathode ray tube the next day.

In this case, when we see those Germans at international academic conferences, their expressions will definitely be very interesting, right?

Zhang Xingjiu was startled by this scene, and he quickly tried to comfort them, telling them that the Germans' research progress was still a long way to go. Only then did they relax for a moment.

After several months, Zhang Xingjiu came up with the final plan after learning that Braun was close to the correct answer. The experimental assistants immediately made the electrode grid, anode, deflection coil, heater, cathode, electron beam, focusing coil, and fluorescent screen according to his ideas, and then put these components together in the correct way. In this way, the first cathode ray tube in human history was born.

This cathode ray tube is perfect. It has only one cold cathode, and the tube is not completely vacuum. It requires a high voltage of 100,000 volts to accelerate the electron beam so that the motion trajectory affected by the deflection can be recognized on the fluorescent screen. In addition, the electromagnetic deflection also has only one direction.

Therefore, there is still a long way to go before it can be put into practical use. In fact, this is the case with any new thing at the beginning. Theoretically speaking, this invention is already relatively perfect, and all that can be done in the future is to improve it. The identity of the first inventor is indisputable.

Sorbonne University once again held a press conference to announce this great invention, and Zhang Xingjiu's paper was published in Nature, once again causing a sensation in the global physics community.

It is said that Braun was silent for a long time when he saw this paper, because his ideas were very similar to Zhang Xingjiu's, but he was a little slower, so Zhang Xingjiu got there first. He now experienced what Professor Thomson of the Cavendish Laboratory felt last year.

After the final exam, Zhang Xingjiu found Lippmann and asked for leave. "Professor, I have been studying in Paris for a year since I left Shaoxing. I miss my hometown very much, so I want to go home and have a look."

The latest novel is published first on Liu9shuba!

"As you know, this trip is very long. Even if we take the fastest cruise ship, it will take two months just to go back and forth. So I would like to take a month off and report to the school in October."

"Haha, only at this moment did I realize that you are still an eighteen-year-old child. Well, kid, go home with peace of mind. I will arrange someone to prepare a boat ticket for you!" Lippmann readily approved the leave.
