Chapter 721: Civil And Military Officials: My Head Is Itchy And I Feel Like I Am About To Grow A Bra
After visiting the newly named [Ban Heng's Solar Furnace], Yan Changqing continued to lead Zhu Yuanzhang and others to a high platform in another area.
As soon as they boarded the high platform, Zhu Yuanzhang and a group of civil and military officials saw people standing on the ground, with a tripod as a support below and a cylindrical thing about one meter long and 150 millimeters in diameter above. .
"What is this?!!"
Zhu Xiongying asked, looking at his teacher who was wearing a Saint Banheng family vest.
Yan Changqing smiled and said:
"Remember the telescope?!!"
Zhu Xiongying nodded. He naturally remembered the telescope. When he and Yan Changqing were surfing the sea in Haizhou City two years ago, Yan Changqing asked the craftsman to make him a telescope.
Of course, not only he had it, but Zhu Jixi, who was also in Haizhou City with him at the time, also had it.
Later, Zhu Gaochi, who also became a disciple of Yan Changqing, was also given a telescope by Yan Changqing.
In addition to these little guys, the senior generals of the Ming Dynasty were also given a telescope by Zhu Yuanzhang.
For example, during the Northern Expedition, Liang Guogong Lan Yu was able to avoid letting go of any of the Northern Yuan barbarian tribes he encountered. The telescope was the primary contributor.
During the Northern Expedition, the scouts always used telescopes to observe the distance. Once they discovered the traces of the Beiyuan barbarians, they immediately sent the news back to the army, and then the army began to disperse and encircle them dozens of miles away.
By the time the Beiyuan Manzi discovered the traces of the Ming Dynasty's Northern Expeditionary Army, the Northern Expeditionary Army had already surrounded the Beiyuan Manzi tribe, and then took advantage of it.
"This object is called an astronomical telescope. Its principle is basically the same as the binoculars you used before: the objective lens is used as a convex lens to condense the light to form an inverted and reduced real image, which is then magnified through the eyepiece to observe the details of distant objects."
“It’s just that ordinary telescopes can only see objects that are hundreds of meters away, or thousands of meters away, but they cannot see objects that are farther away.
"And this is mainly related to the diameter (D), focal length (f), and focal ratio (F) of the telescope "847"!"
"Aperture (D) is the diameter of the objective lens. The size of the aperture determines the resolution of the optical system, that is, the resolution of the telescope."
"The larger the aperture, the stronger the resolving power of the telescope."
"Focal length (f) is the distance from the telescope objective lens to the focus, which determines the size of the image formed by the optical system on the image plane."
"For astronomical photography, the object distance (distance of the observed celestial body) can be considered to be infinite, so the image distance is equal to the focal length, so the image plane is also called the focal plane."
"The longer the focal length of the telescope, the larger the image formed on the focal plane; vice versa."
"Focal ratio (F) is the focal length of the telescope divided by the clear aperture of the telescope, that is, F=f/D. It determines the number of photons received per unit area per unit time on the focal plane.
It is also used as an important indicator of exposure efficiency. "
"The smaller the focal ratio, the more photons are received per unit area on the focal plane; vice versa. In other words, the smaller the focal ratio, the higher the exposure efficiency of the mirror."
"So in order to see the specific appearance of the stars millions of miles away, we need to gather more light, increase the diameter of the objective lens, increase the magnification, and lengthen the length of the lens barrel."
"For example, an astronomical telescope with an objective lens diameter of less than 80 millimeters can generally achieve a magnification of about 100 to 160 times.'
"Under such a magnification, there is no pressure to observe the moon closest to us, and the specific appearance of the moon can be clearly seen.
"An astronomical telescope with an objective lens diameter between 90 millimeters and 150 millimeters can have a magnification of between 180 times and 300 times."
"Under such a magnification, it is not a big problem to observe Venus (Venus) and Yinghuo (Mars) which are closer to the planet below us but smaller in size."
"If it is used to observe the moon, local details can be magnified by more times, and the observation effect will be more shocking."
"The effect will also be better when observing the year star (Jupiter) and the ruler star (Saturn) at the same time."
"The astronomical telescopes we have in front of us now are all astronomical telescopes with an objective lens diameter of 150 millimeters.
Yan Changqing explained the relevant principles of astronomical telescopes in great detail.
But underneath, Zhu Yuanzhang and all the civil and military officials once again showed a stupid look called clarity.
[Hiss, my head is itchy, and I feel like my brain is about to grow!]
[It’s over, Saint Ban Heng seems to really want to teach us, but we really don’t understand it at all!]
[Fortunately, fortunately, it turns out that I’m not the only one who can’t understand it, and no one else can understand it either, so I feel relieved!]
【Is this the knowledge of Saint?!!】
[Obviously I understand every word that Saint Ban Heng said, but when these words are combined together, I can’t understand it at all!]
[Is it true that my whole life’s knowledge is all false?!!]
[Otherwise, why can’t I even understand what Saint Banheng said? 】
[It’s rare to meet Saint giving a lecture, but I can’t understand it. I really have to encounter a treasure mountain but come back empty-handed!]
All civil and military officials, you look at me, I look at you, no one is embarrassed to speak.
Oh, no, there are still people who dare to speak out.
"Dare to ask Saint, you just said that through this astronomical telescope, you can clearly observe the specific appearance of the moon, Qiming, Yinghuo, Suixing and Zhenxing, is it true?!!"
Jian Zheng, the fifth rank of Qin Tian Jian, squeezed in front of the crowd of civil and military officials, looked at Saint Heng with care and asked respectfully.
In addition to the supervisor, there are deputy supervisors of the fifth rank, Chun Guanzheng, Xia Guanzheng, Zhongguan Zheng, Qiuguan Zheng, Dong Guanzheng of the sixth rank, and Wuguan Lingtai Lang of the seventh rank.
The ten people also pushed aside the other civil and military officials unceremoniously, and squeezed to the front together, following behind their boss, Superintendent Zheng, and looking at Saint Ban Heng with the same expressions of anticipation.
The other civil and military officials who were pushed away just wanted to see who was so disrespectful and disrespectful of etiquette, and when they were about to refute a few words, they immediately became silent when they saw that it was a group of officials from Qintian Prison.
Qin Tian Jian is a small department in the court.
On weekdays, most of the time, thousands of Qin Tianjian officials standing in the court are no different from clay carvings and wood sculptures.
Under normal circumstances, they would not speak out, and similarly, the six ministries of the court and other civil and military officials would not involve them in court affairs under normal circumstances.
It's like the officials of the Qintian Prison are standing above the court, but they are alone outside the court.
However, this does not mean that Qintian Prison is unimportant.
Because the authority of Qin Tian Jian is to observe celestial phenomena, calculate calendars, and determine the four seasons!
The celestial phenomena, the four seasons, and the calendar are often related to the farming season. In addition, everyone previously believed that changes in the celestial phenomena directly corresponded to personnel changes, so the status of Qinweijian can be said to be extremely important.
Of course, changes in celestial phenomena and personnel changes directly correspond to this point, which mainly comes from the Confucian "Theory of Influence between Heaven and Man".
Since Yan Changqing won a great victory with the Confucian "Debate on the Theory of Influence between Heaven and Man", this point has basically been abolished.
But even so, in the current era when all people need to farm according to the farming seasons set by Qin Tianjian, the important status of Qin Tianjian still does not decrease by half.
In addition, the Qin Tianjian officials themselves were responsible for observing the sky, calculating the calendar, and determining the four seasons, which sounded extremely mysterious, high-end, grand, high-grade, and important knowledge.
Leaving aside other aspects, if any of their sons or daughters need a wife or get married, they may have to ask officials from the Qinwei Prison to help select ten Yudian hours.
After all, when it comes to knowledge in this area, the officials of Qintianjian are definitely much better than most folk Feng Shui masters.
Moreover, they usually do not have any political conflicts of interest with the officials of Qintianjian in the court.
After all, everyone’s development direction is different.
Therefore, under normal circumstances, all civil and military officials are not very willing to provoke the officials of Qin Tianjian.
After all, if you offend the officials of Qintian Prison, it will be very troublesome if they give you the name of a monster of some kind, or choose a very unlucky day for you or your heirs to get married.
Yan Changqing was a little surprised when he looked at the officials who crowded in front of him, but after recognizing them as officials from the Qintian Prison, he understood.
After all, one of the powers Qin Tianjian holds is the observation of celestial phenomena.
It's just that in the past, the Qintian Prison's observation of celestial phenomena relied on the naked eye. It was impossible to see the specific appearance of the moon and other stars with the naked eye.
And now I heard Saint Ban Heng say that the specific appearance of the stars in the sky can be clearly observed through an astronomical telescope. It is impossible not to be excited and curious.
If there is really a Qintian prison official who is not interested in the specific appearance of Zhou Tianxingchen, it must be a fake Qintian prison official who will turn around and expel him from the Qintian prison.
"It's indeed true."
"Through these astronomical telescopes, we can indeed clearly observe the specific appearances of the moon, Qiming, Yinghuo, Suixing and Zhenxing."
"For example, the moon is actually a sphere whose surface is covered with impact craters that may have been formed by the impact of various small celestial bodies.
"Also, there is no Jade Rabbit, no Chang'é, and no Lunar Palace on the moon."
"At least for now, I'm not aware of their existence."
Yan Changqing looked at Jian Zheng in front of him and the other officials of Qin Tian Jian, and spoke in a gentle tone.
For those who are pious, humble and eager to learn, he will never hesitate to teach them.
After receiving Saint Ban Heng's affirmative answer and a detailed description of the moon, Jian Zheng, the Qin Tian Jian, could no longer resist his curiosity about the astronomical telescope. He immediately bowed to Saint Ban Heng and said:
"I beg you, Saint, to allow me to use an astronomical telescope to see the exact appearance of the stars in the sky!"
The rest of the Imperial Heavenly Supervisor officials, because they worshiped the government:
"I beg you, Saint, to allow us to use an astronomical telescope to see the exact appearance of the stars in the sky!"
For thousands of years, no official of the Qintian Prison has been able to truly see the specific appearance of the stars in the sky.
Now the opportunity is in front of them, if they can't take a look for themselves.
Then they really will not die in peace.
Yan Changqing nodded and then agreed:
"...
"It's just that if you want to observe the specific appearance of the moon and other stars, now is not the right time."
"Because the sun's light is too strong during the day, and other stars either don't emit their own light, or their own light is not as bright and dazzling as the sun.'
"For example, the moon itself is actually a star that does not emit light."
"The reason why you see the moon glowing at night is mainly because it reflects the light that the sun shines on it, so it appears to glow at night."
"Just like now, the moon is actually reflecting the sun's light and shining."
"It's just that the current sun is too bright, covering
The light reflected by the moon is blocked, so you can't see the moon shining at this moment.
"But when night falls gradually and the sun's light gradually dims relatively speaking, you can gradually see the shining moon again."
"So if you want to observe the specific appearance of the moon and other stars, it is best to wait until night to observe, so that you can see more clearly."
"If observed during the day, sunlight will hinder the observation of other stars with the naked eye and astronomical telescopes."
Yan Changqing taught the officials how to use astronomical telescopes while telling the story.
The use of astronomical telescopes is not difficult, at least the officials of Zhongqin Tianjian learned it quickly.
However, as Yan Changqing just said, if you observe during the day, the sunlight will hinder the observation of other stars with the naked eye and astronomical telescope, and you will not be able to see them clearly.
The specific appearance of the moon and other stars.
But then some officials from the Qin Tian Jian thought that the moon and other stars could not be observed for the time being because the sunlight was too strong, so why didn’t I just observe the sun first?!!
The sun is so big and bright. You can definitely see the sun clearly with this astronomical telescope.
So as soon as Yan Changqing turned around, several officials from Qintian Prison covered their eyes and screamed loudly:
"ah!!!"
The commander of Jinyiwei was so frightened that Mao Xiang drew his sword out of its sheath and shouted:
"There are assassins!!!"
At the same time, within a few breaths, Zhu Yuanzhang, Queen Ma, Zhu Xiongying, Zhu Jixi, Zhu Gaochi and Yan Changqing were all escorted by a group of royal guards, patrolling all directions with vigilant expressions.
All other civil and military officials, especially the Dukes and the Six Ministries and Nine Ministers, also tried their best to block Zhu Yuanzhang, Empress Ma and others at the first opportunity.
Yan Changqing, who was urgently escorted by a group of Jinyi guards, looked at the Qintian Prison officials who were covering their eyes at the source of the screams. When he understood what was going on, he immediately pushed away
A group of royal guards said angrily:
"No assassin!"
"There are just idiots!"
Hearing Saint Ban Heng's words, Zhu Yuanzhang, Empress Ma, and all the civil and military officials all looked at him.
"When the sun is at its peak at noon, people can't even raise their heads and look directly at the sun."
"It's a good thing that you actually use an astronomical telescope to look directly at the sun [What's the difference between this and using your eyes to see the sun's rays which are better than those in the prime of life?!!"
"Hurry and send them to the Wanmin Medical College next door and let the ophthalmologists see if their eyes can be saved!"
"If I can't save it, I will be blind after 4.5 years."
After hearing Saint Ban Heng's explanation, all the civil and military officials and the commanders of the royal guards present made Mao Xiang relieved.
If someone really wanted to assassinate the emperor here, I don't know how many of the officials and guards present would lose their heads.
When they thought of this, all the civil and military officials and imperial guards looked fiercely at the Qintian Prison officials who were covering their eyes and wailing.
I was almost scared to death by these fools!
Qin Tian Jian Jian Zheng and other Qin Tian Jian officials on the side also secretly breathed a sigh of relief.
What a risk, they almost had to use an astronomical telescope to observe the sun.
Fortunately, he and others were a step slower, otherwise they would be the ones who might want the eyes at this moment.
However, when he thought that the one who had just made a mistake was an official of their Qintian Prison, the Qintian Prison immediately knelt down and said:
"Please forgive me for disturbing Your Majesty!"
All the other Imperial Heavenly Supervisor officials also knelt down and said:
"Please forgive me for disturbing Your Majesty!"
After figuring out that it was an accident, Zhu Yuanzhang also waved his hand and signaled all the royal guards and civil and military officials to disperse. At the same time, he once again said for a rare moment:
"Forget it this time, if there's another time, I won't let you go!"
"According to what Ban Heng said, take them to the Wanmin Medical College next door!"
Today is the day when Yan Changqing's Wanmin Academy of Sciences is completed and visited. Zhu Yuanzhang did not want to be stained with blood today if it was not necessary.
Lest it be recorded in future history books that when the Academy of Sciences was completed and visited, some officials were killed because of their ignorance and disturbing the emperor.
This is not a good look for Yan Changqing and the Academy of Sciences.
