Chapter 145 1905 years

[Due to an accident, Boeing's Starliner spacecraft was originally scheduled to leave the space station and return to Earth on June 6, but the voyage has been delayed again and again, from the 14th to the 14th, then to the 18nd, and now it has been postponed to the 22th. It is hard to say whether it can return on the 26th.]

[When the passenger spacecraft was rendezvousing with the space station, five of the spacecraft's 28 thrusters failed, but fortunately four were successfully restarted]

[The spacecraft's five helium leaks have not been resolved. After finally successfully rendezvousing and docking with the International Space Station, a new problem has arisen: another oxidizer separation valve of the spacecraft is stuck.]

[The problem is serious now. Not only can the astronauts who have exceeded their service terms not come back, but the two astronauts who have gone up now are also likely to have one-way tickets.]

[After investigation, it was found that the direct reason why the new spacecraft continued to leak helium was that the follow-up throttle solenoid valve installed on it was a substandard product. It was an exaggeration to say that it was substandard. It was simply a counterfeit and shoddy product. This accessory was produced by San Ge’s company.]

[For traditional aerospace powers, the attitude adjustment follow-up throttle solenoid valve is not an absolutely high-tech product, but for countries that have never made such products, it is naturally a super high-tech that is more difficult than climbing to the sky.]

[There are only two companies in the world that can produce this type of titanium alloy throttle solenoid valve, namely Rabbit and Goose. Coincidentally, both of them have been sanctioned by the United States, and NASA has also been banned from cooperating with the two space agencies.]

[Boeing's industry was hollowed out and they couldn't produce anything anymore, so they had to let India do the manufacturing. Why India? Because their CEO is of Indian descent. It's human nature to support fellow countrymen. Of course, Boeing's initial idea might have been to let India be a middleman.]

[I didn't expect that Brother San was either too proud or too greedy. If there is no titanium alloy, is there no aluminum alloy? Haven't you made an aluminum alloy throttle valve, or aluminum alloy doors and windows? Then it looks like this.]

[Now they say that the power is not enough to return safely, so NASA has been trying to find a solution. From the repeated delays in the return date, we can see that this is obviously not an easy problem to solve. 】

[I have to say this, I never dreamed that I would encounter such counterfeit and shoddy products in the aerospace field. It turns out that this world is just a huge makeshift team.]

Jinling City.

"This is really... audacious, but didn't they inspect the parts when they were delivered?" Liu Ji and others were all holding back their laughter. They were obviously amused by this farce. It was no exaggeration to say that this was murder for money.
"So what are CEOs? Isn't acceptance just a process?" Everyone didn't know what the CEO position was, but it was obvious that the position was not low in status, because it could influence the purchase of parts for such a major project, and control the acceptance process to prevent counterfeit and shoddy parts from being introduced.

According to my estimation, one must be at least a shopkeeper to have this right.

Everyone nodded. This practice of supporting fellow villagers could not be said to be wrong, but it was obvious that if one's virtue did not match his position, he would suffer disaster. They had also seen many videos complaining about the unreliability of the third brother before, and they thought it was prejudice.
It turns out that there is no most outrageous thing, only more outrageous things.

"This is what it means to make a mistake by an inch and then have a huge disaster." This vivid farce also taught everyone a lesson, that is, aerospace is extremely rigorous, and a small mistake can lead to a serious accident, especially in the field of materials.

Think about it, at that height, there is really no one to cry out to. If something happens, they can't fall down, they just keep circling around the earth, and even death can't be peaceful. It's impossible for the people on the space station not to panic.

“If this electromagnetic throttle valve is not considered high-tech, then what is high-tech technology?” Zhu Biao and others are yearning for it. Although they have always known that aerospace is difficult, without a standard to measure it, it is difficult to have an intuitive experience.

Now let's start with a solenoid throttle valve, which is not a high-tech accessory. There are only two companies in the world, almost two hundred countries, and there are only three companies including the hollowed-out country of M, that can produce it.

What is dominance?

“A discontinuous lead.”

Zhu Yuanzhang and his ministers were all amazed and shocked, and perhaps even a little proud of it.

Because this is just a point that Tianmu mentioned briefly. Few companies can produce these non-high-tech accessories, let alone other higher-level technologies.

From the first landing and sampling on the back of the moon, we can see that China will definitely be at the leading level in the aerospace field in the future, and other countries will not be able to catch up even if they put eight horses into it.

Hexing Tea and Snack Shop.

"So it was the accessories made by the third brother. That makes sense."

"These astronauts are unlucky to have run into Brother San."

Shopkeeper Wan lowered his head and laughed when he heard this. This was really not prejudice.

From the Ganges, the "king of the periodic table", to the clean and hygienic food, to the people of Jiji confidently saying that SH is a small Mumbai, to the captain of Taiwan complaining about the local air, to the law that can be amended at any time to hit foreign companies hard
Anyway, no one has a temper about this country. It is like a dog-skin plaster. Although it does no harm, it is disgusting.

"Is this considered shooting oneself in the foot, haha?" The man surnamed Chen laughed heartily, not trying to hide the gloating in his smile.

The original International Space Station specifically excluded future generations, and then carried out a series of disgusting actions to suppress and prohibit cooperation.

This is like a snobbish neighbor or relative who is afraid that you will laugh at you.

"This situation is so refreshing now."

"Hahahaha" everyone laughed and didn't stop.

Shopkeeper Wan was in a very good mood and quickly ordered the servants to deliver some free snacks to the diners. For a moment, the store was filled with a happy atmosphere.

"Don't we have the Dragon spacecraft? Even our own people don't believe in it. Go ask Master Ma for help [dog head]"

"Brother, the rocket exploded in front of the two astronauts, directly refusing to cooperate. Which astronaut in the world would dare to board their spacecraft?"

"The titanium alloy valve, the technician of San Ge had a bright idea and changed the material to aluminum alloy [covering face] It's really too outrageous, even novels don't dare to write like this"

[Throughout the history of physics, there have been only two miracle years: Newton’s miracle year in 1666, and Einstein’s miracle year in 1905.]

[At the time, Einstein was still a small clerk at the Swiss Patent Office. He used only his spare time to write 6 heavyweight papers, each of which had the strength to win the Nobel Prize. It can be said that he shocked the world with one battle]

[First, on March 3, Einstein published a paper on the "photoelectric effect", which became one of the cornerstones of quantum theory. This is also the principle of solar panels generating electricity.] [On April 18, Einstein published a paper on measuring the size of molecules, which earned him a doctorate.]

[On May 5 and December 11, he published two papers on Brownian motion, which became milestones in molecular theory]

[On June 6, he published a paper titled "On the Electrodynamics of Moving Bodies". This inconspicuous title was later given a well-known name, called "The Special Theory of Relativity". This paper was so strong that even the Nobel Prize did not dare to comment on it casually, and could only deliberately avoid the theory of relativity when awarding the prize.]

[On September 9, Einstein attached another paper to explain the special theory of relativity, and proposed the famous mass-energy equation: E=mc. Everyone knows the story of this equation later.]

[All of this was created by Einstein alone with pen and paper in the Patent Office. Oh, by the way, in the same year, the Qing Dynasty abolished the imperial examination system that had been in place for more than 1300 years.]

In front of Fengtian Hall.

Zhu Yuanzhang and others were really scared. Unlike their previous ignorance, they knew that only major scientific discoveries could win the Nobel Prize, like the artemisinin that had just been awarded.

Einstein published 6 papers in one year. What a gifted person!
"We already know the mass-energy equation. It only explains an equation in the special theory of relativity." Everyone was stunned by Einstein's arrogance. It was like a poor boy suddenly discovering one day that rich people's cats were picked up and dropped off by private planes, while he had never even been to the airport.

This is the working principle of the most powerful weapon ever invented by mankind, and it was just thrown out like cabbage without even a separate article being published about it.

"Solar power generation has opened up another way of utilizing energy and its significance is very significant." A group of people began to analyze. To be honest, in the six papers, apart from the photoelectric effect and the mass-energy equation, which they could think of as application scenarios, they did not know what the other applications such as measuring molecular size, Brownian motion, special relativity, etc. were.

Tianmu has mentioned quantum mechanics many times before, but he has not been able to gain entry, so it is difficult to comment on quantum mechanics for the time being.

However, judging from the praise from the sky, these discoveries are of great significance.

In the same year, the Qing Dynasty abolished the imperial examination system.

"No wonder it is said that the Qing Dynasty misled China for 300 years." Hu Weiyong said that from a chronological perspective, this land would have to go through nearly 50 years of invasion and war.

"The gap is too big," Liu Ji also said. They have learned so much from Tianmu and deeply understand the gap between the two. Just like the Ming Dynasty today and the Ming Dynasty last year are two completely different empires. The Ming Dynasty, which has various technologies as a backup, has much stronger war potential and economic recovery capabilities than the Ming Dynasty last year.

Therefore, even if people in the science department knew the applications of the photoelectric effect, they still couldn't quite understand its principles.

". Electric current is actually the directional movement of electrons, this is what Tianmu said. At the same time, the outer electrons in the atom have different energy levels. If they receive energy, a hierarchical transition will occur, and it is not impossible for them to even break free from the constraints of the nucleus." Du Ping from the Science Department searched out the relevant knowledge points from his mind. He didn't know if it was correct or not, he just combined the two points together for the time being.

Everyone in the science department's eyes lit up. This was really possible. At least all the knowledge points were correct.

"If light shines on a solar panel and the atoms on the panel absorb energy, electron escape will indeed occur." Zhu Biao paused, "In other words, if the electrons move in a certain direction, then an electric current will be formed. Is this light-generated electricity?"

After Zhu Biao said this, the people in the six ministries understood and praised His Highness for his wisdom. Zhu Biao did not take any credit for it. All of this was Du Ping's idea and he just stated it again.

[The photoelectric effect refers to the phenomenon that when light shines on the surface of certain materials, the electrons on the surface of the materials absorb the energy of the light beam and are excited to generate electric charge. This effect is the basis for solar panels to convert light energy into electrical energy.]

[According to the principle of the photoelectric effect, when a certain type of material is illuminated by light, photons (particles of light) interact with atoms or molecules on the surface of the material. The energy of the photons is transferred to the electrons in the material, causing the electrons' energy levels to rise, causing them to dissociate from the solid.]

【In this way, free electrons and positive ions are formed. Free electrons can move freely, just like a charged particle. 】

[Electrons need a certain amount of energy to break free from the constraints of the nucleus. After an electron absorbs the energy of a photon, part of the energy will be converted into the electron's work function, and the rest will be converted into the electron's initial electrical energy. Then we get E = hv - W0, which is the photoelectric effect equation.]

[However, in reality, solar panels are actually semiconductor pn junctions, which use the photovoltaic effect to convert light energy into electrical energy.]

[As we know, light is composed of a series of light atoms of different colors, red, orange, yellow, green, cyan, blue, and violet. The shorter the wavelength, the higher the frequency, and the higher the energy. In addition to red and violet, there is also some invisible light.]

In front of Fengtian Hall.

"That's true!" Everyone was amazed at Du Ping's level, but Tianmu's explanation was much more detailed. Not only did he complete some basic knowledge about light, but he also systematically explained some details of the photoelectric effect.

In particular, the photovoltaic effect and pn junction were proposed, which confused most people, but the part about light was interesting.

"Light can be decomposed into monochromatic lights of red, orange, yellow, green, cyan, blue and purple through a triangular prism? Can this triangular prism be made of glass?" Because it only flashed across the sky, a demonstration picture was given, and everyone only saw a triangular object made of transparent material, a bit like glass.

"You'll know after you try it."

"We can tell after decomposing visible light, but how were invisible light discovered?" Everyone was very interested, because everything Tianmu mentioned was incredible.

The clerks hurriedly wrote down the photoelectric effect and its equation, as well as the equation for the frequency and wavelength of light.

In fact, people in the science department have summarized some phenomena about light. For example, a wooden stick is half in the water and half on the water surface, and it looks like it is dislocated and broken when viewed from the outside.

For example, I heard that experienced fishermen usually stab the fish from below when catching fish.

But before they could come up with a theory and verify it, the mystery was revealed: the two phenomena were based on the same principle, called refraction of light.
"The photoelectric effect is a high school physics course and is not within the scope of the nine-year compulsory education. Users who don't know about it don't need to feel inferior."

"Electives 3 to 5, a very exciting physics book, which also includes nuclear fusion and nuclear fission, etc. The photoelectric effect should be in the chapter on the wave-particle duality of light."

"If I had listened to this in high school, I would have gotten full marks in physics long ago"

"You're overthinking. The photoelectric effect is worth at most 3 points, and it may not even be tested."
