There are several young people at Eton who are quite outstanding, such as a man named Moseley.
Many people may not know this name, but he was the key figure who first discovered the atomic number.
After that, Moseley worked as Rutherford's assistant and also worked with Bohr.
But it is a pity that Moseley died young. During World War I, he went to the front line as a signal soldier despite his family's objections. As a result, he died on the battlefield at the age of 27.
If he could live one or two more years, he would have a good chance of winning a Nobel Prize.
Moseley also admired Li Yu, and his favorite subjects at Eton were mathematics and physics.
For this kind of young genius, Li Yu could only encourage him as much as possible.
From ancient times to the present, both at home and abroad, there have been many young people who are very talented in science.
Li Yu was quite touched and decided to go back and dig out the young people in the country.
In his past era, the country did not have such good conditions due to years of war. Now that he has traveled through time, he must save a few more geniuses buried in history and time no matter what.
Of course, it is in the field of science. During the Republic of China, there were countless masters in social sciences.
It took Wilson more than ten days to barely build a cloud chamber that could take pictures, but it was still very crude and the sensitivity was average.
The development of experimental instruments must be a big trouble, so we can only make do with it for now.
Anyway, it will take many more years for the Cloud Chamber to be truly effective.
While Wilson was improving the cloud chamber, Li Yu was not idle and completed underwater testing with Rutherford.
Since it is only for the discovery of cosmic rays, there is no need to consider too many phenomena that are already known in Li Yu's mind.
When the electroscope was placed fifteen meters underwater, the radiographic signal could still be received, which already revealed a big problem.
In order to eliminate the influence of water bodies, they drove their cars to many places, even water bodies in caves.
Rutherford studied radioactivity very deeply, and he knew that this was enough to explain the extremely high intensity of the unknown rays.
Rutherford exclaimed: "Where did it come from! What in the universe has such powerful ionizing radiation?"
Rutherford is quite professional. To put it bluntly, cosmic rays are actually ionizing radiation.
But as for where the cosmic rays come from, well, it was an unsolved mystery even before Li Yu traveled through time.
The reason is easy to explain, because most of the cosmic rays are electrically charged (except for gamma photons and neutrinos), and most celestial bodies in the universe have magnetic fields.
Those who have studied middle school physics must understand that magnetic fields will affect the trajectory of charged objects, so when cosmic rays travel through the universe, their trajectory will be affected by various massive celestial bodies.
By the time they finally reached the Earth, they had no idea where they came from, and even their most basic direction could not be determined, so how could they talk about their origin.
Therefore, it is possible to determine the source of uncharged gamma photons and neutrinos. However, their content in cosmic rays is very small, and very precise instruments are needed to detect them.
——This is not an issue that should be considered at the beginning of the twentieth century.
In fact, Li Yu wanted to study cosmic rays because they are quite special. They can be said to be in the field of pure physics and have minimal impact on industry.
But the importance of cosmic rays is not low. After all, it involves the very critical field of particle physics in physics, especially the discovery of antimatter, which is directly derived from cosmic rays.
The energy of cosmic rays is really high. Even the most advanced collider in future generations cannot reach the energy of cosmic rays.
Therefore, cosmic rays were later used as natural colliders to study antimatter particles.
Faced with Rutherford's question, Li Yu spread his hands and said, "I'm afraid it's a bit difficult to know where they come from."
Rutherford asked: "Next time we raise the height of the hot air balloon to the maximum height of 5,000 meters, maybe we will make new discoveries."
Li Yu said: "I just brought Yunshi up. With the photos, they can be used as effective evidence."
To be honest, 5,000 meters is not very high and is within the controllable range of amateur flying enthusiasts. Any higher than that, the requirements for hot air balloons and flight control will be very strict, and only professional meteorologists can achieve it.
But after getting the underwater data, they are definitely looking forward to the high-altitude data.
Because of the new equipment, Li Yu and Owen Richardson did several more sets of data.
Lu Bicheng thought it was fun and wanted to go on a hot air balloon ride.
This was her first time to be so high in the sky, and she was extremely excited after riding in a hot air balloon.
It’s quite exciting within one or two kilometers, and if the weather is good, you can even see the European continent in the distance.
But if the height goes up, it's another concept.
The final goal was 5,000 meters. It was midsummer, so Li Yu and Owen Richardson prepared thick clothes.
Lu Bicheng didn't know why: "What are you doing with leather clothes?"
"At an altitude of 5,000 meters, the temperature will drop by almost 30 degrees, which can basically be regarded as winter," Li Yu said, "otherwise you should not follow."
Lu Bicheng was playing enthusiastically and immediately said: "What is there to be afraid of in winter?"
Owen Richardson said: "5,000 meters is not a particularly dangerous height."
After hearing what he said, Lu Bicheng wanted to go up even more, because riding in a hot air balloon was really exciting.
There was no other way, so Li Yu had no choice but to say to Richardson: "We can only go up to 5,000 meters. Don't go any higher."
Richardson said: "I understand that Glaisher's story is legendary throughout the meteorological community, but it is also a warning that I am not that good at technology."
The Glaisher whom Richardson was talking about was a British meteorological researcher more than 40 years ago. He and another assistant flew to an altitude of 12,000 meters in a hot air balloon without oxygen supply or protective clothing protection.
It was also this experience that allowed humans to know how the temperature changes as altitude increases. There was a movie in later generations dedicated to this dangerous adventure.
And 5,000 meters is still a relatively mature height for now.
After getting ready, a few people started to take off on a sunny morning.
Everything was fine in the beginning, and the data recording went relatively smoothly.
For example, when the ionization degree drops around 700 meters, the ion pairs in the cloud chamber obviously begin to decrease.
It can be seen as a reduction in radiation from the earth's surface.
But at 800 meters, the ionization degree begins to increase again;
At 1,000 meters, the ionization degree is basically no different from the surface.
Most of these have been sensed with electroscope before, but not so obvious.
However, this trend has shown that the radiation does not come from the surface.
The next step is to climb to the highest altitude of 5,000 meters.
It was quite pleasant at first, especially when passing through some clouds, which was quite exciting.
But when the altitude reaches four or five thousand meters, it's a completely different concept. You need to put on thick clothes first.
This was fine, but Lu Bicheng suddenly began to suffer from hypoxia.
The oxygen content in high altitude is not low, but the air pressure decreases, resulting in less oxygen inhaled each time, so symptoms of hypoxia will occur.
Lu Bicheng didn't understand this, but felt a little dizzy and became very heavy, while Li Yu and Richardson on the side were still collecting data carefully.
When she persisted to an altitude of 5,000 meters, she vaguely heard Owen Richardson saying excitedly to Li Yu: "Look, the ionizing radiation is much stronger than that on the surface, it's several times stronger!"
Although Li Yu had known it for a long time, and even knew that the data would be more obvious when it reached 10,000 meters, the results of the experiment by himself were still much more wonderful than seeing them directly from books.
The two were busy recording data and taking photos.
Lu Bicheng gasped for air, finally couldn't hold on anymore and fainted on the side.
Li Yu turned around to see her and was shocked. He rushed over to hug her and asked Owen Richardson to lower his height.
Lu Bicheng's face turned pale and she had difficulty breathing.
Li Yu immediately performed cardiopulmonary compressions on her, while Owen Richardson controlled the hot air balloon and said: "She is suffering from hypoxia and needs artificial respiration!"
Li Yu couldn't care less, held her head, pinched her lips and started blowing.
Owen Richardson was still shouting instructions from the side: "It's too fast! Just 10 times per minute, pay attention to her breathing rhythm!"
Li Yu continued to blow for a long time, and the height of the hot air balloon dropped to two or three thousand meters.
Lu Bicheng finally came around. She slowly opened her eyes and saw Li Yu kissing her...
She instinctively raised her hand to push him away, but she didn't have any strength in her hand. She just touched his face lightly and then dropped it.
Li Yu said happily: "You finally woke up!"
The temperature also increased at this time, and Li Yu reached out to help her unbutton her coat.
Lu Bicheng said feebly: "Taking advantage of others' danger...you...don't..."
Owen Richardson smiled and said: "What you just did was called artificial respiration. If he hadn't helped you recover, it would have been very dangerous."
"Is it dangerous?" Lu Bicheng murmured, and then seeing that Li Yu really had tears in his eyes, he tilted his head and tried to sit up.
Owen Richardson has a lot of experience in high-altitude flying: "It's all our fault for not paying attention to your situation in advance, otherwise we would have lowered our altitude after two or three thousand meters."
Lu Bicheng said softly: "Did I delay your work?"
Li Yu comforted him softly: "There was no delay. It has been completed and the data has been recorded."
Lu Bicheng held her still heavy head and said, "That's good."
The hot air balloon descended slowly. When it reached the ground, Lu Bicheng had recovered somewhat. In terms of physical condition, she was actually not bad.
Of course, altitude sickness is not necessarily related to a person's physical condition. Some very strong people may have much stronger altitude sickness than children.
Li Yu helped her get off the hot air balloon. Lu Bicheng was a little embarrassed when outsiders were around, but it was true that her head was still dizzy.
Li Yu picked her up and put her in the passenger seat of the car, and took her to the hospital first.
Fortunately, the situation was not serious and the doctor just asked her to rest for a day or two.
On the way back, Lu Bicheng didn't say a word and sat quietly in the passenger seat. In her mind, she vaguely saw Li Yu doing artificial respiration while in the sky.
My face began to turn red unconsciously, and my breathing became a little heavier.
Li Yu quickly asked: "Are you still feeling unwell? How about we stay in the hospital for a day?"
Lu Bicheng quickly turned her head: "No... no need... I, I'm fine."
Li Yu asked: "It's all my fault. I forgot to tell you about the changes in temperature and air pressure as the altitude increases. The smell will drop by about 0.6 degrees for every 100 liters of altitude, and the air pressure will also drop. This is harmful to the lungs and
Hemoglobin will be affected..."
Lu Bicheng said: "I understand, I don't blame you, I went up myself."
Li Yu said: "I was really scared just now. You suddenly fainted at such a high place, and you didn't bring any oxygen equipment or treatment equipment. You were totally helpless."
Lu Bicheng whispered: "You don't seem to be so at a loss..."
Li Yu said: "Forget it, this is my first time to give artificial respiration to someone. If it weren't for Mr. Richardson's guidance, I would have done it wrong."
Lu Bicheng asked: "He... didn't do it, right?"
Li Yu said: "No, I did it all. I was the first to notice that I hugged you and never let go."
"That's good..." Lu Bicheng turned her head and said, "Thank you..."
Li Yu laughed and said, "I have nothing to thank you for, as long as you are fine!"
Lu Bicheng grabbed the corner of her clothes: "It's okay, of course it's okay, and..."
"And what?" Li Yu asked.
"It's nothing." Lu Bicheng bit her lip.
Li Yu didn't dare to ask any more questions. He couldn't figure out the mentality of girls in the late Qing Dynasty and the early Republic of China. Anyway, it would definitely not be like that of later generations.
They were currently staying at a hotel in London. Li Yu helped her back to her room. The person who opened the door was Konoe Akiyuki. They were still staying in the same superior suite.
Konoe Zhaoxue saw Li Yu holding Lu Bicheng tightly, while Lu Bicheng still had a large blush on his face. He was shocked and asked: "You guys..."
Li Yu explained: "I just came back from the hospital and the doctor said she needs to rest."
"Hospital?" Konoe Akiyuki was even more confused.
Li Yu had no choice but to say: "She followed us for a high-altitude experiment and developed symptoms of hypoxia. By the way, she needs more care from you in the past two days."
Lu Bicheng pushed Li Yu away: "Sister Zhaoxue is enough. Go back and see Mr. Richardson. Don't you still have important data to sort out?"
After Lu Bicheng finished speaking, she hurried into the house.
"=I will come and continue to see you tomorrow!" Li Yu said, and then looked at Konoe Aoyuki, "Thank you, Miss Aoyuki."
What else could Konoe Akiyuki say, so she agreed: "Don't worry, I've also learned medical knowledge."
After Li Yu finished explaining, he turned and left.
Konoe Akiyuki immediately came to Lu Bicheng's room, where she was putting her hand to her lips in deep thought.
"Sister, are you okay?" Konoe Aki asked softly.
Lu Bicheng came back to her senses: "I'm fine, I just have a headache."
Konoe Aki thought of how they looked when they arrived, and coupled with Lu Bicheng's demeanor at this time, something was obviously wrong. Could there be any substantial progress?
Konoe Akiyuki was also a little nervous, wishing she didn't get on the hot air balloon with her.
Looking at Lu Bicheng's rosy cheeks at this time, even she felt that she had a kind of touching beauty that I felt pity for.
Konoe Akiyuki had always thought that she had a chivalrous style, but at this time, the womanly scent she naturally revealed was something that a vigorous young man could not resist.
Konoe Aki suddenly felt that her advantage was no longer so obvious.
She still had a strong sense of observation. Looking at Lu Bicheng's lips, she seemed a little swollen, so she asked, "Sister, do you need some cold water for you?"
Lu Bicheng said quickly: "No, sister Zhaoxue, I just want to have a good rest."
Konoe Akiyuki asked: "Is it really unnecessary?"
Lu Bicheng said: "It's really not necessary."
Konoe Aki had no choice but to exit the room: "I'm in the next room. My sister can call me anytime if anything happens."
