Chapter 188 Determining the plan to return to the UK; Can you win the Nobel Prize in Physics?
After the time entered October, Li Qiwei was dismissed from his post and became unemployed.
Shi Mei is basically solely responsible for the affairs of Guangdong University.
He himself is stationed at Huangpu Institute of Technology, taking classes during the day and studying the detailed planning of the City of Science at night.
Every Saturday and weekend off, he would take a boat up the Pearl River and return to his home in the city, where he would work hard and sow seeds.
On Saturday it was Wang Luyao and on Sunday it was Xiang Lan.
After traveling through time, Li Qiwei was worried that his physique would be changed. He was afraid that he would not be able to have children, which would be a pity for him.
And next, he will go to Europe again to think of ways to plan land.
If nothing else happens, Li Qiwei has decided to leave the country and go to Britain at the end of 1908 or early 1909.
It just so happens that he can lead the first batch of Huangpu Polytechnic undergraduate students and accumulate rich experience for the school.
This time, he didn't want Wang Luyao and Xiang Lan to struggle with him. It would be better to wait until he was stable and move them all to the City of Science.
So, he wanted his second daughter to get pregnant as soon as possible so that he could take care of the child in China so that he would not be alone.
He is a man who wants to build a scientific family, and he must have as many children as possible.
And in China, with huge family resources, the living conditions and safety of children are much better than abroad.
Li Qiwei is 24 years old, Wang Luyao is 23 years old, and Xiang Lan is 21 years old.
In this era, 23 years old is already an older woman. Girls from ordinary families usually get married and have children at the age of seventeen or eighteen.
So Li’s mother often urged Li Qiwei not to be busy with his career all the time. The continuation of the family was the fundamental plan.
Li Qiwei agreed very much with this, which made Li's mother very happy.
In the bedroom, Li Qiwei is accompanying Wang Luyao tonight, and the two are talking about each other.
Li Qiwei confessed to Wang Luyao that he would leave the country in four years and build a science city.
He told Wang Luyao all his plans without reservation.
"Lu Yao, I don't want you to suffer at all."
"When I go to Europe again this time, I want to lay a foundation that will last forever and leave it to our children."
“I hope you can understand me and support me.”
Wang Luyao did not show the expected surprise. She just gently touched Li Qiwei’s cheek and said, “Mr. Work hard.”
"I don't want any foundation, I just want peace."
"No matter what you do, I will always support you."
When Li Qiwei heard these words, he felt Worth it.
"I'm sorry for you and Xianglan, I want you to wait for me."
"Don't worry, it can be as short as 5 years or as long as 10 years. Regardless of success or not, I will always be with you. Together.”
Wang Luyao smiled and said: "Then I want to get pregnant as soon as possible and give birth to a child. I can take the child to see you in the future."
Li Qiwei teased her: "How can one child be enough? I want you to give birth to a litter for me." ”
Li Qiwei knew that the little witch must feel lost in her heart, but she was unwilling to show it in front of herself.
So, he wanted to use his fiercest love to make up for the other party.
Thirty minutes later.
"Ms. sir, is your method really effective?"
"It's been three minutes, I'm so tired."
At this moment, Wang Luyao was holding his thighs with both hands. , with pillows underneath.
Since getting married, Wang Luyao has called Li Qiwei Mr. Qiwei instead of brother Qiwei. This is a change from a girl to a young woman.
“Don’t worry, this is a technique I learned in my physiology class at Cambridge University.”
"Just hold on for two more minutes and it will be fine."
Li Qiwei started to lie. Online classes were also classes. He had studied the curriculum styles of universities in various countries in his previous life.
Wang Luyao blushed with embarrassment, "Bah, Westerners are really not ashamed. Such things can be studied openly."
Li Qiwei chuckled, "Okay, the time is up, let's start. Let’s do the next exercise.”
Wang Luyao couldn’t resist and finally fell asleep.
——
In mid-October 1904, Science Weekly took the lead in reporting the 1904 Nobel Prize winners as quickly as possible.
Thanks to Li Qiwei’s educational reform, science and engineering teachers and students in domestic universities now regard the Nobel Prize as a benchmark.
The Nobel Prize in Physics, the Nobel Prize in Chemistry, and the Nobel Prize in Physiology or Medicine represent the highest honors in the field of natural sciences.
At the same time, they also represent the cutting-edge research directions in these fields in the future.
This year’s Physics Nobel Prize winner is also Ridgway’s acquaintance, John Strutt, also known as Lord Rayleigh.
The reason for his award is: the measurement of the density of hydrogen, oxygen, nitrogen and other gases, and the discovery of argon due to the measurement of nitrogen.
After seeing the report, students from the School of Physics of Huangpu University of Technology found it incredible. They thought this result was too simple.
Measuring the density of a gas is just mass divided by volume. I think I can do it.
In class, some students questioned this.
Li Qiwei is very pleased. He is happy to see young men dare to question authority, but they must also correctly understand the strength of their seniors.
So, he explained patiently: "Lord Rayleigh is my mentor's mentor. After all, he is in the same lineage as our Huangpu Institute of Technology."
"Evaluating a Physicist The achievements of the scientist must be substituted into the physical environment he was in at that time."
"Gas density measurement is just one of Lord Rayleigh's many achievements."
"As early as 1815. In 2000, the British chemist Plaut published a paper "
"He believed that the density of various gases is exactly an integer multiple of the density of hydrogen."
"It can be deduced that hydrogen atoms may be meta-particles of various elements, that is, any element is composed of different numbers of hydrogen atoms "This is Plaut's hypothesis about the hydrogen parent material of the element"
"Now of course we know that this hypothesis is wrong, but at the time, physicists and chemists were wrong. Scientists could not find strong evidence to falsify it."
"In 1882, Lord Rayleigh spent ten years accurately measuring the densities of hydrogen and oxygen."
"Because the scientific instruments at that time were very crude, and this kind of experiment required high precision, it took Lord Rayleigh so long."
"The experimental results showed that the ratio of the atomic weights of hydrogen and oxygen Not 1:16, but 1:15.882.”
“This strongly proves that Plaut’s hypothesis is wrong.”
At this point, the students in the classroom were extremely excited. I admire Lord Rayleigh's perseverance.
To solve a problem, I have been conducting experiments for ten years.
No one would have lasted that long without a true love for physics.
Only at this moment did they realize the gap between themselves and the top physicists. People here thought that it would be difficult to persist for ten years.
Li Qiwei took in the students' expressions, smiled slightly, and continued: "Of course, this is not over yet."
"Lord Rayleigh later accurately measured the density of nitrogen. ”
“He used two methods to obtain nitrogen ”
"The first is to fractionate nitrogen from liquid air, and the second is to separate nitrogen from ammonium nitrite."
"Lord Rayleigh was very careful, and he found that the nitrogen obtained in two ways There is a very small difference in density. "
"The density of nitrogen in liquid air is 1.2572, while the density of nitrogen in ammonium nitrite is 1.2505."
"If it is young physics. Scholars or students may take it for granted that this is caused by experimental errors."
"But the experienced Lord Rayleigh is very confident in his experiments."
"He firmly believes that this result must have unidentified reasons at work."
"Nitrogen obtained by chemical methods must be pure, so the nitrogen in the air must be mixed with other substances."< br>
“For this reason, he put forward a hypothesis that there is an allotrope of nitrogen in the atmosphere.”
At this time, several students were confused and didn’t know what the same form was. What does metamorphosis mean?
Seeing this, Li Qiwei directly ordered, "Yan Renguang, you have also taken a chemistry course. Come and tell us what allotropes mean."
Yan Renguang did not expect that Li Qiwei would nod at him. The envious looks from his classmates made him extremely proud. He immediately decided to take another life science course tomorrow.
“Allotropes refer to two or more substances. The elements that make up them are the same, but the properties of the substances are different.”
“For example, oxygen and ozone, both It is composed of oxygen elements, but they are two different substances."
Li Qiwei smiled and nodded, "Yes, very correct"
"I suggest that everyone can learn from Yan Renguang. Students, if you have enough spare time, take a few courses in other majors.”
"This is very helpful in broadening your thinking."
"Okay, let me continue."
"Lord Rayleigh believed that nitrogen also has an allotrope. He modeled it on ozone O3 , named it N3."
"Later, the British chemist Ramsay saw Lord Rayleigh's paper, and he was very interested."
"So the two scientists collaborated. , after rigorous experiments, it was finally determined in 1894 that N3 was not an allotrope of nitrogen. ”
"It is a special monatomic gas that has never been discovered. Its properties are very inactive, and its content in the atmosphere is only 0.93%."
"Lord Rayleigh and Ramsay put it It was named [argon], which means inactive in Greek.”
“The first inert gas was discovered”
“Later, in Lord Rayleigh’s work. With his help, Ramsay discovered several new noble gases."
"Now, do you still think that Lord Rayleigh's achievements are ordinary?"
A heated discussion suddenly broke out in the classroom.
It turns out that there are so many unknown stories behind a simple experiment.
At this time, they understood the greatness of physicists.
It took more than ten years to finally figure out a problem.
Physics is indeed profound and profound.
At the same time, the students were impressed by Principal Li's talent of being knowledgeable and knowledgeable about ancient and modern times.
That’s too much to understand.
Li Qiwei smiled and said nothing. He would not tell these rookies that he had come thousands of times to do this.
“These stories were told to me personally by Lord Rayleigh.”
“The real situation is actually dozens of times more difficult than this.”
"Physics research requires not only talent, but also hard work, opportunity, cooperation, care, platform, etc."
"The platform is the most critical, it can enhance your horizons."
"So, now that you have such good conditions, you must study hard."
"In the future, I will select the outstanding ones and send them to Cambridge University for further study, so that you can see how the world's top physicists are like Doing research.”
After giving some education, Li Qiwei did not forget to draw a pie.
It made these students scream in excitement, and at the same time, it also subtly changed their ideas.
Li Yaobang: Doing business? What a crap business!
Zhang Yihui: Be an official? Be a shitty official!
Yan Renguang: Add another math elective course tomorrow!
