Chapter 282 Should I not need to eat an axe... What a slot? (8.2K)
"What?"
In a small shed.
William Whewell was flipping through the observation records in front of him, and asked Xu Yun and others with curiosity:
"Professor Gauss, classmate Luo Feng, is this the 'Conan Star' you are looking for?"
I only see this moment.
On several of the observation records in his hand, a small dot was drawn with a circle.
Only a few traces of these small dots can be seen with the naked eye. They can definitely be found if you look carefully, but they are likely to be ignored at ordinary times.
Xu Yun smiled and nodded. He had simply checked the image just now and could confirm that Gauss had found Pluto:
"That's right."
William Whewell seemed to be a little confused. He compared the two black and white photos and muttered:
"But in these two photos, one is on top and the other is on bottom. How can we tell that they are the same star?"
Xu Yun curled his lips at Gauss when he saw this, and both of them showed a hint of helplessness on their faces.
no way.
Many times, front-end scientific research projects are like this.
The results that scientists have worked so hard to achieve are somewhat inexplicable and confusing to some people.
However, those people are not necessarily malicious denials or brainless arguments, but there are real cognitive barriers.
When seeing some data that exceeds common sense, the question will arise subconsciously: "Can modern technology achieve this kind of accuracy?"
For example, LIGO in later generations.
Everyone knows that it has detected gravitational waves, but few people know how incredibly accurate this thing is.
Its arm is 4km long, and the light path is reflected 400 times inside, so the laser light path length reaches 1,600km.
This isn't the end yet.
The gravitational waves it detects are essentially fluctuations coming from more than a billion light-years away with an amplitude of one thousandth of the proton radius.
This is like a typhoon raging in the Pacific. You throw a stone on the shore of Shanghai, and he detects the ripples caused by the stone on the beach in California.
How many ordinary people can avoid being confused?
Therefore, some practitioners Xu Yun knew would explain something to others in WeChat Moments or Weibo at first, but then they simply stopped caring about it.
Broken.JPG.
This is still the case in 2022, let alone 1850, when the modern scientific system was just established.
For a philosopher like William Whewell, the logic of finding an inner planet through calculation is indeed outrageous.
Of course.
Fortunately, besides William Whewell, there were still many understanding people at the scene.
Such as Faraday.
Such as Riemann.
Such as Weierstrass.
Another example is those students majoring in mathematics and natural sciences.
With these people present, Gauss's efforts would not turn into a question: "Is this thing real?"
Then Xu Yun looked at Gauss. Seeing that the little old man was in good spirits, he said:
"Professor Gauss, please start positioning."
position.
This concept is not difficult to understand.
It is to lock the position of Pluto at this moment through the previously calculated orbit.
This is also the last part of today's observation mission.
As we all know.
Planets and stars are in motion all the time. Planets revolve around stars, and stars revolve around the center of a galaxy or star cluster.
However, due to the different orbits and distances.
Most stars are basically stationary to humans, while planets often appear in different positions at different times.
For ordinary people, the four stars that are easier to find among the four seasons are metal, wood, fire and earth.
Because they are basically in the same orbital plane as the Earth, if the Earth's orbital plane is used as the reference, the difference in orbital inclination angle between them is even less than 5 degrees.
This orbital plane is the ecliptic.
That is to say.
If you want to find metal, wood, fire and earth, just look for it in the sky area near the ecliptic.
As for the locking of the ecliptic, there are many ways.
For example, you can use your mobile phone to download an electronic star map, and you won’t be able to click on the wrong place, so you no longer have to worry about your studies.
You can also use your own eyes to infer the ecliptic plane by looking for constellations near the ecliptic.
Among them, the most recognizable ones in spring are Leo and Virgo.
The line connecting the constellations in front of Leo forms a sickle shape. The brightest one at the bottom is Regulus, and the area next to it is the ecliptic.
Summer is Scorpio and Sagittarius.
The ecliptic passes between Scorpio's pincers (Falcon) and the heart (Antares).
In autumn, Pegasus is the constellation. The two stars on the east side extend about double the distance to the south, which is the position of the ecliptic.
In winter, it is the constellation Taurus, and the ecliptic is between Aldebaran and the Pleiades star cluster. (I suggest you give it a try. It’s quite interesting. I taught a buddy this method, and later he used this method to pick up a girl at a barbecue stall.
, real people and real things)
Planets other than metal, wood, fire and earth are more difficult to locate.
For example, Mercury can only be barely observed after sunset or before sunrise, and Uranus and Neptune require the assistance of MATLAB scripts.
As for Pluto?
This thing is really outrageous.
Its orbital inclination is 17.1405 degrees, and its axis of inclination is close to 120. It can almost be said to be spinning while lying down.
Even in 2022, not many people can calculate Pluto's orbit with bare hands.
Under normal circumstances, a polytechnic university probably only has two or three.
However, people's abilities are different. For Gauss, this step is all he needs to do.
I saw him picking up the pen and quickly calculating on the paper according to the calculated orbit formula.
five minutes later.
A set of data appears:
Right ascension 06h42m10.38726s, declination 08°23′22.4764″.
Angular diameter 0.065″-0.115″.
The oblateness rate is <1%. (This is the coordinate of Pluto on November 17, 1950. It cannot be calculated in 1850. I don’t know why the VSOP87 module crashes as soon as it is turned on. Is i3 already like this now?)
Xu Yun then took the piece of paper to the astronomical telescope and handed the piece of paper to Hubert Airy's father, George Bedell Airy, the current director of the Greenwich Observatory.
This was the condition Xu Yun negotiated with Hubert Airy in the cafe that day, and it was also one of the reasons for persuading George Bedell Airy to help.
In other words, the discovery of Pluto was used to eliminate the pressure of public opinion exerted on George Bedell Airy.
Therefore, the final star search process naturally fell to George Beadle Airy.
And to be honest.
The astronomical telescope in 1850 had many small parts. You could ask Xu Yun to operate it roughly, but he really didn’t have the ability to do micro-operation.
George Bedell Airy took the note, looked at Gauss, and then looked deeply at Xu Yun.
The time has come to decide whether your choice is right or wrong.
Or to be precise
It's time to decide whether everyone is tired tonight, or whether they have worked all night in vain.
Under heavy pressure.
Even though George Bedell Airy had rich experience, he still felt a little uneasy at this time.
Then he took a deep breath and came to the telescope.
The star position was corrected based on the coordinates.
Pluto in 2022 is retrograde in Capricorn, while Pluto in 1850 was still wandering near Orion.
Of course.
The words "retrograde" and "wandering" here both refer to the picture from the perspective of the earth. On the scale of the universe, their actual distance is more than thousands of light years.
Following the coordinates given by Gauss, George Bedell Airy quickly found one of the targets:
Orion B molecular cloud complex.
This complex had a very domineering name in later generations, called "Cosmic Lightsaber":
One of the adolescent stars released two jets into space, like a laser sword, showing powerful and terrifying power.
Other than that.
There is also a nebula called NGC2068 within this complex.
Of course.
Compared with the number NGC2068, its other name is a little more well-known:
M78 Nebula.
That's right, it's the M78 where the Kingdom of Light is located.
M78 looks like a patch with a small telescope, and has two stars with visual magnitudes 10 and 11, so it is easy to find.
Unfortunately, Ultraman Gauss is not a native of the Kingdom of Light.
Otherwise, Gauss should feel a special sense of joy when he sees Gauss's hometown.
After locking this star area.
George Bedell Airy controlled the worm to fine-tune it, then calibrated the polar axis and tightened the screws.
In less than half a minute, the starry sky was completely locked.
Some astronomical telescopes in later generations will be equipped with digital display screens, but the technical level these days is not up to standard, so when faced with the right ascension and declination to two decimal places, there is only one method:
Use rulers to segment the finderscope.
I saw George Bedell Airy, a tall man, taking out a caliper from his body and turning it with a crunching torque.
Then he bent down and took measurements on the finderscope like a brown bear gnawing on a honeycomb.
In 2022, the Greenwich Planetarium once exhibited a longitude and latitude scale from the early 20th century. The accuracy can reach about five to six decimal places, and the accuracy is relatively good.
"10.3853610.38542"
ten minutes later.
George Beadle Airy, who had been mumbling data, suddenly let out a loud sigh, dropped the longitude and latitude scale, and rushed to the eyepiece to observe.
A few seconds passed.
He raised his head ecstatically and said loudly to Xu Yun, Gauss and others:
"I found it, I found Conan!"
Hear this.
The scene with hundreds of people watching was silent at first, and then a burst of noisy discussion broke out.
Upon seeing this, Gauss looked at Xu Yun and quickly came to George Bedell Airy's side:
"Director Airy, you have found Planet Conan? Are you sure?"
“One hundred percent sure!”
George Beadle Airy patted his chest and gave up his position at the same time, giving up the observation point to Gauss.
Gauss nodded to him in thanks, walked to the observation position, and began to look into the eyepiece.
George Biddle Airy stood respectfully beside him, providing guidance for Gauss's observations:
"Conan's star is located in the upper right corner of the viewing angle. There are no other celestial objects around it. There are two stars with vertical angles close to a straight line in the three fields of view on the left."
Following the prompts from George Bedell Aire, Gauss soon found the planet:
This is a planet that is not particularly bright. It occupies a corner of the starry sky alone, with no stars around it.
as if
grim Reaper.
Then Gauss slowly raised his head from the eyepiece and gave up his position to Faraday.
Another half minute passed.
Faraday was replaced by Xu Yun.
After Xu Yun leaves the observation point.
He turned around and looked at Faraday and Gauss, and the three of them nodded at the same time.
Gauss puffed up his chest, looked around with sharp eyes, and said loudly:
"Professors and classmates, all look at me. I have something to announce!"
"That is"
"Not long ago, we successfully discovered the ninth planet in the solar system!"
"Tonight is a miracle night worthy of being recorded in the history of science!"
The voice fell.
Wow
There was a burst of cheers at the scene.
Faraday and Gauss are currently the first people in the fields of physics and mathematics in the world, and because mathematics is the core of the classical education system, Gauss's influence is even greater than that of Faraday.
With these two big guys as guarantees, there is obviously no need to question the authenticity.
As for Faraday and Gauss, who forcibly identified a certain celestial body as Conan's star to save their own face?
joke.
This is a discovery that is enough to shock the European scientific community. There will definitely be a large number of astronomers observing the trajectory.
If it is a lie, within three to five days, maybe an astronomer in London will expose it tomorrow night.
In fact, it is the same in every era. A lot of people yearn for the top spot in their respective industries.
Therefore, if this kind of thing is achieved, it will be successful, and if it is not achieved, it will be unsuccessful.
There is no such thing as covering up failure for the sake of so-called face.
Seeing the tense atmosphere at the scene, Xu Yun glanced at Lao Tang covertly.
Lao Tang nodded towards him and waved to the side knowingly.
soon.
GuluGulu
A student federation cadre came to the scene with several telescopes.
It was mentioned in the Northern Song Dynasty copy.
Pluto's apparent magnitude is between +13.6 and +14.03, making it a dark star.
There is an empirical formula for the aperture of the telescope, which can easily calculate the limit magnitude ml of the telescope.
This formula is ml=2.1+5lgD, D is the diameter of the telescope in millimeters, and lg is the logarithm.
It is not difficult to calculate according to the formula.
As long as it is an astronomical telescope with an aperture of 288 mm or more, you can see Pluto under good weather conditions, provided that the light pollution is not too serious and it is not at aphelion.
Although Cambridge University does not have many astronomical telescopes of this size in stock, there are still five or six in actual number.
According to Xu Yun and Lao Tang's plan.
After Pluto is discovered, these telescopes can be moved to the site to allow as many students as possible to observe Pluto with their own eyes.
Thus.
The students' sense of participation will be much higher than that of the photoelectric effect, which is very beneficial to the observation itself, the Gokumon Society and even natural science.
as expected.
When these telescopes arrived at the scene, the atmosphere immediately reached the climax tonight.
A large number of students gathered at the telescope eyepiece, hoping to see the ninth planet in the solar system with their own eyes.
"Let me be healthy!"
"You stepped on my foot!"
"I saw it, I saw it! Didn't you say that Conan's star is very dark? Why does it feel so bright to me?"
"You see a barren, then it is Rigel, the star discovered 19 years ago! Can the star not be bright?"
"Classmate, do you want to join our Gewu Club? It doesn't cost any money, just add whatever you want."
Just as the scene was bustling with excitement, George Beadle Airy also came to Xu Yun's side.
I saw the director of the Greenwich Observatory looking full of emotion at this time, and said to Xu Yun seriously:
"Classmate Luo Feng, thank you very much this time."
George Bedell Aire's words were really not polite. Looking at tonight, there were only two people he was most grateful to.
One is Gaussian.
Now he can be said to have both reverence and gratitude for Gauss because he is also an astronomer and knows how difficult it is to lock a planet through mathematical calculations. In other words, it is not something humans do at all.
I am grateful because with the discovery of Conan Star, the pressure on myself will be reduced drastically!
He will change from a slow person who missed the discovery of Neptune to a positive figure who supports emerging disciplines and has the courage to explore the universe!
Even in the past little while, he was thinking about finding connections and getting relevant reports out as soon as possible.
And another person for whom George Bedell Airy was grateful was Xu Yun.
From a process perspective, tonight's observation can be divided into several links.
Such as manpower mobilization, equipment debugging, data calculation, file classification and final observation, etc.
If evaluated from a single stage, Xu Yun may not be the person who made the greatest contribution at each stage.
For example, the manpower mobilization is attributed to Faraday, the equipment debugging is attributed to the Greenwich Observatory, and the quantity calculation is attributed to the mathematical team.
But if all stages are integrated, then Xu Yun is undoubtedly the well-deserved first contributor.
to some extent.
This young oriental man is the real driving force in creating this miracle.
Opposite him.
Looking at George Beadle Airy who looked much more relaxed, Xu Yun smiled and waved his hand:
"Mr. Airy, you praise me too much. I just rely on my ancestors."
The words are not finished yet.
Xu Yun suddenly felt an itch on his neck.
He subconsciously turned his head and found Aveline looking at him with a smile not far away.
""
Xu Yun was frightened by Aveline's gaze. He quickly shrank his neck, gave in decisively, and changed his words:
"Mr. Airy, I'm not being modest. I just did a small amount of work. It's just words on paper, but I can't count it. I can't count it."
George Bedell Ally looked at him deeply, without going into too much detail, but changed the topic and said:
"By the way, classmate Luo Feng, have you decided on Conan's alias?"
Xu Yun was slightly startled:
"Alias?"
"Yeah, another name."
George Beadle Airy, bit by bit, explained:
"For the discovered stars, in addition to the standard name, we will also assign an alias to it."
"For example, Mars is Mars, the god of war in Roman mythology, Mercury is Mercury, Europa is Europa, etc."
"Mr. Fat Fish was the first to formulate the derivation process of Conan's star, and Mr. Gauss and Professor Faraday also expressed their intention to give up the right to name it."
"So the task of naming it falls on you. After all, you are the only descendant of Mr. Fat Fish."
Xu Yun nodded clearly.
Giving nicknames to celestial bodies is a common custom both at home and abroad.
For example, Mars is called Mars in Europe and Yinghuo in the East.
Another example is that Venus is called Aphrodite in Europe, Taibai or Morning Star in the East, etc.
There are countless similar examples.
And because of that humiliating history in modern times, Europeans have always taken the initiative in naming rights.
In later generations, many stars were named after European mythological figures.
But the current Faraday or Gaussian.
Even George Bedell Airy, the future president of the Royal Society, has a pretty good reputation in history.
In addition, in this timeline, the status of the 'fat fish' has surpassed the differences in race.
Therefore, George Bedell Airy generously gave up the naming rights to Xu Yun.
As for Xu Yun?
Naturally, I am happy to accept this kind of kindness.
He had seen a lot of weird things in his two lifetimes, but he had never had the experience of naming a celestial body.
But what nickname should I give Pluto?
How about calling it Su Song to commemorate Lao Su, the pioneer of Eastern astronomy?
Not good, not good.
Old Su is not dead yet.
Pluto's original semantics are a bit unlucky, and the planet's environment is extremely cold, not to mention that it will be downgraded in the future, so it is inappropriate to use Lao Su's name.
Otherwise
Choose a name that can form a CP with Conan?
For example, Hattori Heiji, Kidd or Genta?
Doesn't seem appropriate either
Who should I call?
Between thoughts.
Xu Yun suddenly caught a glimpse of Frederic Agar Ellis and his father Vittorino Ellis who were hurriedly retreating out of the crowd with a livid face.
See this situation.
Xu Yun's eyes suddenly lit up.
I saw him turning his head, smiling and saying to George Beadle Airy:
"Mr. Airy, maybe Conan's nickname is 'Ellis'."
"After all, this star was discovered under the 'care' of Earl Ellis."
"I think future generations should be reminded of the contribution of Count Ellis when they mention Conan. What do you think?"
George Bedell Aire blinked and raised his eyelids and glanced at Vitorino Ellis.
His son Hubert Airy was also a student in the Department of Mathematics, so after the meeting, he naturally repeated Vittorino Ellis's remarks to him.
be honest.
George Bedell Aire was somewhat dissatisfied with this statement...
Because he was also one of the "whimsical people" mentioned by Vittorino Ellis, he was inexplicably bombarded by the map.
At the same time, as supporters of natural science, nobles such as George Biddle Airy and Vittorino Ellis also had certain differences in their positions.
Therefore, facing Xu Yun's proposal, he agreed without much hesitation:
"Okay, I also think the name Ellis is good. Its real name in Greek is Valis, which means cold lowlands. It is obviously the most suitable name to describe the planet Conan."
Although the exact distance to Pluto is not yet known.
According to the Titius-Bode rule, Pluto is about thirty astronomical units from the sun, so the temperature of that planet must be extremely low.
Using Valis to describe it is quite vivid.
Then George Bedell Airy chatted casually with Xu Yun for a few words, then turned and left the scene.
Seeing the retreating figure of George Bedell Aire, Xu Yun couldn't help but touch his chin.
Poisson's spot had been discovered by Mavericks in advance because of the letter he wrote to Mavericks, and his name was changed to Newton's spot.
That is to say.
Due to my own reasons, this timeline lacks a slap-in-the-face allusion.
So now that I have given the world a new allusion, I can be considered to be in peace.
Reasonable.JPG.
Then Xu Yun suddenly thought of something again, lowered his head and touched the ax at his waist.
Feeling the hard edge of the axe, Xu Yun breathed out lightly:
"Very good, it looks like you don't have to talk anymore this time."
As a result, the words were not spoken.
From a small shed not far away, a somewhat familiar voice suddenly came:
