Just out of the dragon pool, he entered the tiger's den again. After just enduring the "torture" of the vacuum pump for five hours to take a picture, Chen Muwu entered the laboratory next door again, following Stoner, irradiating different atoms with X-rays every day, observing their Different states between different energy levels.
We obviously know the results of the experiment, and we also know what the theory behind the experiment is, but we can't say that the feeling of being forced to keep secret is really uncomfortable.
After hanging out in the laboratory for more than half a month, Chen Muwu felt that he really couldn't wait any longer.
After finally completing another experiment on potassium atoms and obtaining the same results as before, he advised Stoner to try writing a thesis.
At this time, it was time to leave for Belgium. Chen Muwu asked Stoner for a copy of the experimental data. He planned to take advantage of these few days of travel to write a first draft, and then go to the Solvay Conference to announce his own This new paper.
Because Chen Muwu and Rutherford talked about the graduation thesis, Rutherford initially asked him to use electron diffraction experiments to do his doctoral thesis. However, because this paper had a collaborator out of thin air, and as the funder, Deb Luo Yi also wanted his name to appear in large physics journals.
Therefore, Chen Muwu could only write this paper that verified that electrons are also wavelike after the electron diffraction experiment was completed, and then submitted it to British and French journals.
Now these two papers with the same content but different languages have been published in the corresponding journals in April. Some physicists have already got them, while others are still on the road.
But Rutherford disagreed with Chen Muwu's idea and used a theoretical paper explaining the electron orbit (that is, the exclusion principle) as his graduation thesis.
He even said to Chen Muwu, half jokingly and half angrily, that it was enough to have a theorist Fowler in the Cavendish Laboratory. If Chen Muwu wanted to be a theorist, he would have to at least wait until Fowler retired, or let Bo I became the director and transformed the laboratory into the Cavendish Institute for Theoretical Physics.
There is no other way. If Chen Muwu wants to graduate this summer, he can only come up with another experiment.
So after thinking about it for a few days, Chen Muwu came up with two ideas about the new experiment.
The first is to repeat the Davidson-Germer experiment in which low-speed electrons were used to bombard a metal surface to prove the wave nature of electrons.
But as Zweig said in "The Great Tragedy", the first to arrive has everything, and the second to arrive is nothing.
Although the first arrival was also himself.
But since he had already conducted an electron diffraction experiment using high-speed electrons, doing another experiment with low-speed electrons would be the icing on the cake, but it would not add much.
Moreover, the Davidson-Gemmot experiment had lower accuracy and larger errors. In the original space-time, Thomson did the high-speed electron diffraction experiment just to reduce the error after learning the results of this experiment.
Second, since electrons have been proven to be wavelike, we can use electrons with wavelengths shorter than light to develop electron microscopes with higher resolution than optical microscopes.
Of course, it is unlikely that Chen Muwu can make a real thing with his bare hands in a short period of time, but he should write down the principles, draw structural diagrams, develop a small component, such as an electronic lens or something, and then apply for a patent. no problem.
Although the vacuum pump was not paid for by Chen Muwu, the Yankee still made tearfully $6,000 from his experiment.
He must also get this money back from them hundreds or thousands of times.
Of course, these are just ideas that exist in his brain now, and Chen Muwu did not immediately start preparing for experiments.
Because de Broglie invited them to leave a few days early to visit Paris, France, and then join his teacher Langevin and other French scientists there, and then it would not be too late to set off for Belgium together.
Anyway, it’s only a four-hour drive from Paris to Brussels by train.
They were accompanied by Blackett, in addition to Rutherford and de Broglie's servants.
Because with the help of Chen Muwu, Blackett discovered the process of nuclear transmutation and oxygen-17 in photos at the end of last year in advance, which allowed him to successfully obtain the Moseley Scholarship.
Henry Moseley is still a graduate of Trinity College. He is also a British physicist whose main research direction is X-rays.
However, his life was not very good and he died young when he was less than twenty-eight years old.
But it was not disease that killed Moselay, but war.
In 1914, he had just resigned from the University of Manchester and planned to teach at Oxford University.
Then, when World War I broke out, Moseley responded to the British government's call to the battlefield. In the summer of 1915, in Gallipoli, Turkey, he died after being shot in the head by a Turkish sniper.
Compared with Moseley, Eddington, who refused the British government's military service because of his religious beliefs, was undoubtedly much luckier.
If Moseley had not signed up to join the army, but stayed in the laboratory and continued to do experiments, then he would most likely have won the Nobel Prize in Physics in 1916 (the award had a bye that year, and he would not have won the second prize in 1916). Reissued annually).
His death forced the British government to adjust the scope of conscription.
In order to commemorate him, Moselay's family also spent their own money to establish a scholarship named after him.
Blackett is the second person to receive this scholarship. The money can support him to conduct a one-year exchange activity at a foreign university or research institute.
In the end, Blackett chose the University of Göttingen in Germany. The reason why he came here was to study the energy levels of atoms with Professor James Frank.
Frank and Gustav Ludwig Hertz in 1914, because the Frank-Hertz experiment named after their two surnames proved the quantum nature of atoms, in original space and time, which would lead them to obtain the Nobel Prize in 1925. Bell Prize in Physics.
The Hertz above is not the Hertz who experimentally proved the existence of electromagnetic waves and had the unit of frequency in the International System of Units named after him, but his nephew.
Because whether you are going to Germany or Belgium, you must first cross the English Channel and arrive in Calais, France, so Blackett also chose to go with them.
Chen Muwu is happy that his good friend can get this scholarship to study abroad.
However, it can only be said that he was happy too early, and he never thought that if Blackett left so early, he would be the one to suffer for him next.
De Broglie, who was not short of money, waved his hand and asked the servant to buy a full set of first-class carriage and cabin tickets and boat tickets for everyone to Paris.
Although Blackett was also a shy character who didn't like to talk much, with Dirac in front of him, de Broglie's impression of him suddenly became much better.
After staying in Cambridge for more than a month, de Broglie could not escape the temptation of mahjong. After Kapitsa taught him, he soon fell deeply into it.
Now that we finally had enough time, as soon as we boarded the ship from Dover, de Broglie pulled everyone to the bar on the ship, and the four of them built up the Great Wall around the card table.
After playing a few rounds, Chen Muwu found that although he was Chinese, his poker skills were far inferior to those of the foreigners who had to play one or two rounds every day. The few pocket coins he had in his hand were losing less and less.
Ce Na, who has been winning glory for the country in the field of physics for so long, did not expect that he would lose his place in the national quintessence.
Chen Muwu just planned to use the excuse of being tired from the journey to leave the card table after finishing the game. Unexpectedly, a hand stretched out from behind, pointed at the two in front of him, and said in fairly standard Mandarin: "Play. this."
