Readers who have been kept by a rich woman in this life should know this.
The only disadvantage of having a self-propelled ATM around you is that it easily consumes steel balls...
Wrong, wrong.
It is easy to develop a lazy mentality.
But on the other hand.
It’s really cool to have money...
Although Xu Yun is not taken care of by Aveline now, he does feel the pleasure of being surrounded by a rich woman.
It was only a week after the party broke up.
Evelin followed Xu Yun's previous request and prepared a simple Michelson interferometer on time.
Next weekend.
The members gathered again in the activity room of the Gewu Club to prepare for the Michelson-Morley experiment.
be honest.
This set of interferometers is much simpler than the official version of the Michelson interferometer. It is at most a youth version.
"The Point Guard Is Here"
Not to mention the arm length, it is only one-tenth of the official version.
In addition, there is neither plated spectroscopic film nor glued compensation film.
The entire set of equipment looks more like a weaving machine tool than a scientific research instrument.
But on the other hand.
For most members of the Gewu Society who come from poor families, this is already a very rare set of instruments.
After seeing the youth version of the interferometer placed in the activity room.
Except for Hubert Airy, a 'second-generation researcher' who had been surrounded by instruments since he was a child, almost everyone couldn't help but screamed and rushed forward to take a look at this set of equipment.
Xu Yun and Aveline sat at the back of the activity room, watching the members go crazy with a calm expression.
A few more minutes passed.
Feeling that the time was almost up, Xu Yun stood up, walked to the podium table, and clapped his hands towards the audience:
"Okay, classmates, please be quiet and listen to what I have to say."
The scene suddenly became silent.
Then Xu Yun looked around, looking at the many members whose faces were still blushing, and said with a smile:
"Dear students, as you can see, what is in front of you is a simple 'fat fish' interferometer."
"Although it is still a billion points away from the full version, it is enough for everyone to conduct an initial experiment."
"So without further ado, let's start preparing for data calculation."
After speaking, he paused, picked up the sign-in form from the table, and added:
"Well... our club has a total of 32 members. Today, Pinto, a student from King's College, took leave due to illness, and Mr. Thomson was busy with student union affairs and did not attend."
"That is to say, after deducting the two vice-presidents, Aveline and I, there are now a total of 28 people left."
"These 28 people can be divided into four groups, respectively responsible for the observation of light sources, m1 mirrors, m2 mirrors and interference fringes. What are your intentions?"
The members looked at each other and answered:
"no problem!"
five minutes later.
The 28 members were divided into four groups and prepared for the experiment according to their respective division of labor.
Introduced earlier.
There are only two key points in the Michelson-Morley experiment:
The first is to find the direction of the horizontal light path, which is the direction of the earth's revolution.
The second is to adjust the length of the light arm so that the light reflected by m1 and m2 produces qualified interference fringes.
Other than that.
The rest is pretty much common sense.
For example, the bright area of the interference fringe is when the optical path difference is equal to 0 or an integer multiple of the wavelength, and the dark area is when the optical path difference is equal to 1/2 wavelength or an integer multiple of the wavelength plus 1/2, etc...
This is also one of the characteristics of many early physics experiments:
The production and assembly of the equipment is not complicated, but the plan is very sophisticated.
So it only takes a few minutes.
The activity room was filled with the sounds of discussions and exchanges among various groups:
"Harle, where is the direction of the earth's rotation? Is it clockwise or counterclockwise?"
"It's from west to east, you idiot, but you are still a descendant of Magellan!"
"...The light arm is 1.0 meters, Senior Homo, do you need to be more precise?"
"No, can someone pass me the protractor?"
"The m2 mirror can be moved a little further to the left. The angle seems to be less than 90 degrees..."
The Michelson-Morley experiment was first conducted in 1887. As of 2022, it has been repeated countless times by countless scholars.
The related accuracy has reached an extremely terrifying level in terms of numbers.
Although at the time of Xu Yun's time travel, the Michelson interferometer had been gradually replaced by new equipment such as the dual-frequency heterodyne interferometer in front-line experiments.
But in essence, it is just similar to Jay Chou. It seems to have faded out of the music scene, but its influence still continues.
Don't say anything else.
The LIGO interference device that measures gravitational waves actually uses the principle of the Michelson interferometer.
It's just that LIGO's core technology is relatively advanced and can observe interference through changes in the metric tensor, which involves deeper concepts and algorithms.
For example, there is an "old antique" Michelson interferometer from 2003 on the campus of the University of Science and Technology, with an accuracy of 5.29x10^-11 in terms of △δ. Xu Yun tinkered with this thing once.
However, even with the above-mentioned precision, the measurement results in the ether are all from a plane overlooking Chengdu - 0 and 1 are everywhere and nothing is found.
So for Xu Yun.
The results of today's Michelson-Morley experiment are a proper open-book examination, and no other results are possible.
So after explaining the relevant matters.
He handed over the scene to the four groups and took Aveline to the door:
"Eveline-san, what happened to the things I asked you to prepare for the second experiment?"
Aveline looked up at him and confirmed:
"You mean beryllium tubes and hollow solenoids?"
Xu Yun nodded:
"That's right."
After hearing this, Aveline took out a piece of paper from her pocket. When she flattened it out, she found that it was the one Xu Yun had given her last week.
However, what is different from a week ago is that there are some more labels at the end of the dozen or so parts.
Aveline then handed it to Xu Yun, pointed to the label on it and explained:
"Parts marked with [√] that have been fired, and those marked with [X] mean that we haven't found a craftsman who meets the skills yet, so we may have to wait a little longer."
"[O] refers to projects where the technicians and equipment have been prepared, but the production materials are still on the way, so construction has not started yet."
Xu Yun nodded to indicate that he understood, took the piece of paper, and read it carefully.
Xu Yun previously listed a total of fourteen items of parts, but now there are eight items marked with [√], four with [O], and two with [X].
Among the two parts that Xu Yun regards as the most important, one has a √ behind it, which means that construction has started.
The other one is marked [O], which means the furnace can be started after the materials arrive.
See here.
Xu Yun couldn't help but let out a sigh of relief.
Very good, everything went well.
Then he handed the paper back to Aveline, glanced through her hair, and said:
"Thank you for your hard work these days, classmate Aveline."
Aveline nodded with deep sympathy:
"It's true that signing checks is so tiring."
Xu Yun: "......"
Then he suddenly thought of something, looked at the rich woman up and down, and asked:
"By the way, classmate Aveline, did those so-called Newton Jazz fanatics say anything after you skipped class last week?"
Aveline spread her hands towards him, with an expression on her face that said, "You still have to ask?"
"Of course. Didn't you see those weekly articles printed by the Royal Society the day before yesterday?"
Xu Yun touched his nose, shook his head and said:
"Um...Sorry, I didn't subscribe to those weekly magazines. What did they say?"
Aveline put her index finger on her chin, thought for a moment and then uttered a few words:
"In a nutshell...the end of the world?"
Then she lowered her left shoulder slightly, slid down her backpack, took out a few more newspapers, and handed them to Xu Yun.
Xu Yun reached out and took it.
As soon as he bought it, he noticed several huge titles:
"So depraved that the only descendant of Sir Isaac Newton actually skipped class in public!"
"Anija Folger's critical commentary: It's not too late to return to the classical teaching model"
"It's over! The descendants of Newton have torn off the fig leaf of emerging mathematics!"
"Xu Qian, the watchman at Westminster Abbey: Wails were heard in Newton's mausoleum at night, and the coffin shook, apparently crying to shame future generations."
.........
Looking at these scary titles, Xu Yun couldn't help but whistle:
"Good guys, now you can report to the UC shock department."
Then he handed the newspapers back to Aveline, looked at the girl's thin figure, and asked:
"Classmate Aveline, it's only been a week and this has happened...will you still be able to bear it next?"
Aveline met his gaze for a few seconds and shrugged:
"If I choose to retreat, then your next preparation will be meaningless. Then wouldn't I become a traitor?"
"The Escu family does not have Gallic ancestry and will never surrender casually when encountering difficulties."
"I have already contacted Prince Albert a few days ago. At least until the end of this year, I can be myself without worrying about those people's glassy hearts."
Xu Yun blinked.
Good guy.
Judging from what this girl means, she is completely betting on herself.
But it's normal to think about it, after all, he is a descendant of Lilani.
In the original deduction, Lilani, that naughty kid, dropped out of school at the age of 15 to work outside because of his childhood obsession. After saving up enough travel expenses, he ran off to the Netherlands alone.
Even going a little further.
William Askew was also a fool, and he ended up in the situation he was in because he refused to engage in human trafficking.
The ancestors were like this, let alone the descendants like Aveline.
And while Xu Yun was talking to Aveline.
Lao Tang's figure suddenly appeared at the corner of the woods not far away.
Now that he has become the president of the Federation of Students, Lao Tang is really addicted to officialdom, and his aura also takes on the color of a person in power.
He walks like a dragon and a tiger with a strong posture.
But Xu Yun noticed.
Although Lao Tang's aura was strong today, his face was slightly solemn and he looked like he was in a hurry.
After Lao Tang came to the two of them, Xu Yun greeted him naturally and asked curiously:
"Good morning, Mr. Thomson, didn't you say you had a meeting to hold today?"
"Well, good morning, Luo Feng, Aveline."
Lao Tang hurriedly said good morning to him, and then explained:
"The meeting has ended. The main discussion is about some matters at the Cambridge exhibition area at the World Exposition - although your analytical engine is a big killer, the school also has some other exhibits at the exhibition, and all aspects must be prepared and discussed."
Hearing this, Xu Yun nodded with understanding.
There are thousands of students and teachers at Cambridge University, and its history spans hundreds of years. Naturally, it is impossible to bet all the money on yourself.
Although judging from the current situation.
Apart from the Analytical Engine, it is basically impossible for Cambridge University to make a comeback with anything else.
But whether it can be done is one thing, and whether it can be done is another.
So in the past period of time, Lao Tang has been busy tinkering with these tasks.
It can be regarded as the first test he faced after becoming the president.
If he can pass this test, he will at least be able to securely enter the House of Commons in the future.
Then Lao Tang glanced at Aveline who was side by side with Xu Yun, remained silent for a moment, and said:
"Classmate Luo Feng, I learned some news not long ago, and I feel I should tell you."
Aveline picked up her backpack very wisely and asked generously:
"Do you need me to avoid it?"
Lao Tang did not speak, but turned his attention to Xu Yun.
The implications of this move are obvious:
What he is going to say next involves a certain amount of secrets. It is best not to let too many people know, but it is not exaggerated enough to keep it absolutely confidential.
Whether to keep Aveline or not depends on the person involved, Xu Yun.
Of course.
If Aveline is left behind, the corresponding responsibilities will also be borne by Xu Yun.
So Xu Yun simply shook his head:
"No, Aveline is not an outsider. Mr. Thomson, if you have anything to say, just say it."
Lao Tangjian said he looked around and led the two of them to a more secluded place.
Then he took a deep breath and said slowly:
"Classmate Luo Feng, according to the news I got not long ago..."
"About a week ago, several bodies were found in Scotland."
"Corpse?"
Xu Yun didn't expect this word to come out of Lao Tang's mouth. He was slightly stunned and asked subconsciously:
"Mr. Thomson, what does this news have to do with me?"
But the next second.
He suddenly thought of something, and without Lao Tang's explanation, he asked:
"Wait a minute, Mr. Thomson, are those corpses... Orientals?"
Lao Tang's brows were knitted tightly into a ball, and the expression on his face was a little solemn:
"I can't tell for sure. Those corpses were badly damaged. Judging from their skin color and clothing, they should all be Orientals."
"These corpses are scattered in different areas, there are about seven or eight in total."
"According to time estimates, their death date was about four to five months ago, that is, September or October 1850."
"Because the place where the bodies were dumped was very hidden, they were not discovered until recently - spring is coming soon, and some hunters will go into the mountains to set traps, and these remains were discovered."
"At the same time, the areas where these corpses are distributed are connected together, which happens to be from Aberdeen Port to the British territory, among which..."
Speaking of which.
Lao Tang suddenly paused.
His eyes were tangled and he stopped making any sound.
But Xu Yun continued what he said:
"That includes the forest where we first met, right?"
Lao Tang nodded slightly.
Xu Yun took a deep breath and forced his face to calm down as much as possible:
"Mr. Thomson, you mean... that I am related to those dead Orientals?"
Lao Tang was silent for a moment, then suddenly turned his head and looked into the distance, and said leisurely:
"The House of Commons today sent an Inspector to inquire of me about the matter, and I told him that I met you on the way to Falkirk, when you had been in Glasgow for several months."
Xu Yun was stunned subconsciously, and then a warmth surged in his heart.
The Aberdeen that Lao Tang mentioned is a port located in the northeast of Scotland.
Both Glasgow and Falkirk are in the west of Scotland, and their routes have no intersection at all.
To know.
Due to technical limitations these days, there is no means of locating or recording journeys for future generations.
Except for the wealthy and powerful who carry waist cards, it is very difficult to lock down the action trajectories of civilians.
In addition, Lao Tang is here as the president of the Cambridge University Student Union, so what he said is still very weighty, at least in the current situation.
This approach undoubtedly has a strong emotional tendency and can be regarded as "covering up".
And by saying this, Lao Tang basically avoided the abnormal attention Xu Yun might have encountered.
After all, he and Xiaomai can be said to be the only parties involved.
Oh, by the way, wheat.
Thinking of Xiaomai's name, Xu Yun realized another reason why Lao Tang looked in a hurry:
"Mr. Thomson, you rushed here as soon as the meeting was over. Could it be because..."
Lao Tang nodded heavily and moved his chin in the direction of the activity room:
"Well, in addition to informing you of this matter, I also want to give Maxwell an instruction."
"After all, no one knows whether the inspector will ask him to find out the situation. If that stupid kid tells everything without knowing the inside story, all the efforts will be in vain."
After saying that, Lao Tang exhaled a long breath, and a cloud of white mist instantly gathered in the air.
He looked at Xu Yun solemnly and said:
"Luo Feng, you saved my life and Maxwell's. After coming to Cambridge, I, a senior, didn't help you much. Instead, I received a lot of favors from you."
"So there are some things that Maxwell and I will keep in mind, so you don't have to worry."
"It's just that you have to know the unknown Easterners yourself, because I heard..."
"Some of the corpses had bullet marks on their bodies."
Xu Yun's pupils suddenly shrank.
Then Lao Tang patted Xu Yun on the shoulder and strode towards the activity room.
it is more than words.
After the old soup disappears.
Xu Yun was silent for a long time, then suddenly turned to look at Aveline and asked:
"Classmate Aveline, can I trust you?"
Aveline stared at him for a few seconds and smiled:
"What do you think?"
Xu Yun just nodded, quietly approached her ear, and whispered:
"Aba Aba...Aba Aba..."
After listening to Xu Yun's request quietly, Aveline readily agreed:
"No problem, leave it to me."
Xu Yun breathed a sigh of relief.
be honest.
In fact, from the very beginning of the dungeon, Xu Yun noticed the anomaly of his ‘time travel’:
His body is injured.
Also based on the description of wheat.
When he and Lao Tang found him, he was no longer breathing and was completely a "corpse" - just without gunshot wounds.
That's why Wheat dug a hole and planned to bury himself in it.
After learning this information at that time, Xu Yun realized that he might have some identity in this timeline.
This identity does not necessarily have to be high, and there is a high probability that the halo directly affects the settings added to the timeline:
In other words, there are no moral issues caused by the so-called "soul travel". Xu Yun is still Xu Yun, and the so-called past is just an added character.
But there must be some story about ‘himself’, or it may involve some people.
Otherwise, there is absolutely no need for Halo to come up with such an appearance.
This vigilance reached a whole new level after realizing that it was now after 1850.
1850.
This can be said to be an important period in the history of modern science. The real big guys gathered together, and you can see a dream lineup just by looking up.
Look at the people who appeared during this period:
Xu Yun alone has dealt with people such as Wheat, Lao Tang, Faraday, Gauss, Riemann, Darwin, Joule, Weber, Stokes, Lister, and Babbage.
Others who have not come into contact with include Helmholtz, Nightingale, Pasteur, Mendel, Schleiden, Clausius, Avogadro, and Charlotte Bo, the author of "Jane Eyre"
Ronte wait...
During this time period, Xu Yun was able to come into contact with too many well-known figures in the history of science.
In later game terms.
This is a sandbox-like copy.
Physics, chemistry, biology, mathematics and even literature and music can be chosen at will, with great freedom.
In addition, the halo also provides an unprecedented multi-stage mission, so Xu Yun has always been paying attention to the possible impact of his identity.
now......
The unexpected happened.
Although the information brought by Lao Tang is a bit vague.
But just the words corpse and bullet marks were enough to make Xu Yun wary.
Bullet marks...
Although firearms seemed to be very developed in 1850, the main stage of firearms was still on the frontal standard battlefield.
Nowadays, even the police in London can only use sticks.
In this situation.
An unknown number of people will attack Easterners. The danger level of enemies armed with firearms is at least five stars.
Therefore, he made some impromptu arrangements and made some arrangements through Aveline.
be honest.
This is actually a very risky gamble.
Because certain things were obviously not suitable for appearing in this timeline and were forbidden weapons, Xu Yun had never thought of using them before.
If it weren't for Aveline's identity and the things he had experienced before, Xu Yun would never have spoken at this time.
He wanted to ensure that this thing would only appear once and be destroyed after use. At the same time, the production process would not be passed down to the world.
But there is no way.
After all, once the mission fails, the punishment will be an increase in male ketone favorability. Xu Yun doesn't want to be a big man when he returns to reality...
ten minutes later.
Listening to the commotion in the activity room such as 'the stripes really didn't move' and 'how is this possible', Xu Yun couldn't help but take a deep breath:
"The rain is about to come and the wind is blowing all over the building..."
...........
With the emergence of the experimental results of the simple Michelson interferometer, the atmosphere in Gewu Society changed as Xu Yun expected:
Although many people still firmly believe that the instrument is too simple and the sensitivity is too low, thus affecting the final calculation results.
But there are also many people who have doubts about the existence of ether.
Under this mentality.
Many members met frequently to discuss experimental plans while also completing the craft work required by Xu Yun.
As for Xu Yun...
Although nothing happened after Lao Tang sent the notice, he still did not dare to relax.
We are always alert to sudden events.
that's all.
Four months have passed by in a flash, time has come quickly...
The opening day of the International Industrial Exposition.
at the same time.
Another piece of news reached Xu Yun’s ears:
The Qing delegation has arrived in Britain.
.......
Note:
It was supposed to be 10,000 words today, but as I was typing, I suddenly broke out in a cold sweat, my heart was beating so fast, and I put my hand on the cap of nitroglycerin. Fortunately, it was fine in the end, but I didn’t dare to continue typing.
I have been coding all night every day since the 24th. I overestimated my health a bit, and the shortfall of 2,000 words will be made up in two days.
On the last day of the month, I want 5,000 votes, so please don’t keep your tickets...
