Chapter 300 Fish: I have endured pressure that I shouldnt have to bear (6.4K)
Ten minutes after the image was exposed.
The eel Kirchhoff bought back had been disemboweled, its head drooped to the side, and a strange light shone in its eyes.
Riemann took the ring he took out from the belly of the fish and walked to the faucet to clean it a few times.
After the blood stains and stains have been cleaned away.
Riemann held the ring between his index finger and thumb, put it in front of his eyebrows, looked at it, and said to Gauss:
"Teacher, this is a metal ring. It seems to be made of silver... Hey, it has words engraved on it."
Gauss raised his head and glanced at him, put down the water glass in his hand, and asked:
"What is it written about? Great Chuxing King Chen Sheng or the Supreme Lord of the Rings?"
Li Manxu stared at it for a long time, and finally shook his head:
"The words are too blurry to see clearly."
Gauss didn't pay much attention to this, but turned his head and asked Faraday:
"Michael, it is indeed a metal ring. How did you think that the ray could produce such an image?"
When Faraday heard this, he exhaled a long breath with emotion on his face.
Then he pointed to the vacuum tubes lined up on the table and said to Gauss:
"Friedrich, do you remember the various props we just tried?"
Gauss was startled when he heard this, but he quickly replied:
"of course I remember."
Faraday stood up, motioned for everyone to follow him to the operating table, pointed to the metal he had tried and said:
"You see, the steel plate is completely light-blocking, the wooden board and the book are completely light-transmitting, and the thin aluminum sheet is light-transmitting to a certain extent."
"So I was thinking about a problem just now..."
"Is there anything in the world that contains a small amount of metal and is also doped with other substances?"
"The answer is yes, that is..."
As he spoke, he looked around, pointed at Gauss and others with a smile, then pointed at the fish, and said:
"vertebrate!"
After hearing this, Gauss was silent for a moment, thought for a moment, and then a word came out of his mouth:
"calcium?"
"Bingo!"
Faraday rarely snapped his fingers, and it could be seen that the electrical giant was a little excited at this time:
"That's calcium!"
Speaking of calcium, many people subconsciously think of calcium carbonate.
That is, limestone, the main component of marble.
On this basis, some people will regard calcium as stone foam, thus creating the illusion of non-metallic content.
But actually.
It is easy to see from the gold characters it contains.
Calcium is not a non-metal, but a metallic element.
It is located in the 4th period, Group IIA, in the periodic table of chemical elements, and appears as silver-white crystals at room temperature.
The most abundant metal element in the human body is calcium.
at the same time.
The discoverer of calcium was none other than Humphrey Davy, who introduced Faraday:
In May 1808.
David mixed moist quicklime and mercury oxide in a ratio of 3:1, placed it on a platinum sheet, and connected it to the positive electrode of the battery.
Then a hole was made in the mixture, mercury was poured in, a platinum wire was inserted, and connected to the negative electrode of the battery, a larger amount of calcium amalgam was obtained.
Then he distilled the calcium amalgam and obtained silver-white metallic calcium.
And in the human body...or the bones of vertebrates.
Calcium is mainly present in bones and teeth in the form of crystals, accounting for 1.5% to 2% of the total body weight. It is an extremely abundant mineral in the human body.
So as David's deputy.
After Faraday discovered that there were differences in the penetration effects of mysterious rays on different metals, he naturally thought of the concept of bones.
But it was mentioned earlier.
In today's timeline, the scientific community has a relatively deep understanding of the particle properties of light.
They know that the particle flow will carry a large amount of energy, and the energy may have an impact on the human body.
Just like raindrops, hail, and sandstorms in the macroscopic world, it will hurt if they hit your face.
Therefore, after careful consideration, Faraday chose eels as his experimental subjects.
The eel doesn’t have any objection anyway, right?
Then Faraday put the negative on the table and analyzed it carefully with everyone:
"Look, this is the brain and pharynx...the jaw arch is very obvious, and the lingual arch is blurry..."
"In addition, the spine and ribs are also very clear..."
"Is this the intermuscular bone under the fin? You can photograph such small spines clearly..."
"Look at its mouth. It's round, deep and moist. If the teeth are pulled out, I have a bold idea..."
after awhile.
Gauss raised his head thoughtfully, looked around, and concluded:
"Based on the imaging results, it seems that the calcium in the bones will absorb this mysterious ray, and the internal organs will be penetrated by it."
"Therefore, when light of the same intensity is injected, different image results will be presented on the film according to the distribution of bones and internal organs."
"As for whether other substances in animals' bodies will affect the mysterious rays, we don't know yet."
"I think with everyone's intelligence, it shouldn't be difficult to understand the significance of this situation, right?"
As Gauss said these words.
The atmosphere in the laboratory suddenly became quiet, and the sound of a needle dropping could be heard for an instant.
Everyone present today has an unusual background. They are either stable versions of big bosses or youthful versions of future big bosses.
So for them.
The deeper meaning of Gauss’s words is not difficult to understand:
This ray can produce images for fish, so naturally it is also applicable to the human body.
If the conditions are right, transfer this ray from the eel to the human body...
So at least in the field of medicine, there is the possibility of breakthroughs in many difficult and complicated diseases!
For example, a fracture, a lump in the body, or trying to remove the bullet after being shot...
This is undoubtedly an epoch-making discovery for modern medicine.
In addition, its characteristics such as wavelength and frequency are bound to cause a major earthquake in physics!
Think of this.
Weber, who was standing next to Gauss, was excited in his heart and could not help but feel a sense of deep joy.
This chapter is not over yet, please click on the next page to continue reading! He was glad that he was not absent from such an experiment today.
Today, whether it is the measurement of cathode rays, the calculation of the charge-to-mass ratio of the particles composed of rays, or the discovery of unknown rays, any of them has a status and value that will be recorded in history.
If one person is like this, let alone all three together.
It can be said like this.
Every one of these people present today, including the eel and the fisherman selling fish, will definitely be recorded in the history of physics.
To some extent.
The achievement of everyone today is not that they discovered something, but that they worked together to open a door to a whole new world.
Even just looking at the light coming from the door is enough to imagine the magnificence and vastness inside.
At this moment.
Weber, who was regarded as the top electrician in the world and even in the history of science, could not help but think of four words:
What a blessing.
Weber couldn't help but look at Gauss, rolled up his sleeves, and said excitedly:
"Friedrich, in that case let's try it on the human body, and I'll be a volunteer!"
However, Gauss waved his hand towards him and stopped him:
"Edward, don't worry, let me check something first."
After saying that, he turned around and came to the sink where the eels were.
This was originally a cleaning tank for chemical equipment, but now it is temporarily used as a shelter for eels.
After arriving at the pool.
Gauss put on his gloves, picked up the knife that Riemann used to kill the fish, and continued to dissect along the eel's abdomen.
Two or three minutes passed.
Looking at the scene in front of him, Gauss's breathing stagnated slightly, and he waved to Faraday and others:
"Michael, come here and take a look!"
Upon seeing this, Faraday put down the film, quickly came to Gauss, and asked:
"What happened? Friedrich?"
Gauss took the cut eel to the platform of the washing pool, pointed at the edge of the knife and said:
"Look."
Faraday and others took advantage of the situation and took a look.
I only see this moment.
On the belly of the eel cut open by Gauss, some parts of a certain piece of fish that should have been pink and tender suddenly turned black!
Then Gauss took a knife and picked out the fish meat, revealing the fish liver underneath.
Generally speaking.
An eel will have a liver and gallbladder in its body. The gallbladder can be used as medicine, but the liver is not recommended for consumption.
Fresh eel liver is navy blue, a transitional color between blue and black.
But at this moment.
More than one-third of the liver in front of Gauss and others has become...
light yellow.
Then Faraday tried to touch it twice, and then tentatively said to Gauss:
"Has the protein and fat inside gone bad?"
Gauss took off his gloves with a solemn expression, turned on the faucet, rinsed his hands, and replied at the same time:
"Yes, if I guessed correctly, that mysterious ray should be very destructive."
"If you are exposed to it for too long, the fat and protein in your body are likely to be severely denatured."
"Fortunately, we are not in a hurry. Let's try it with this eel first. If you and I were to do it ourselves, I'm afraid our human body would suffer some irreversible damage."
It's a coincidence.
At this time, the eel's nerve cells were not completely dead, so it suddenly flapped its tail twice, startling everyone.
In the corner where Gauss didn't notice, Xu Yun also nodded.
The concept of protein was proposed by the Dutch scientist Gerrit in 1838. It is not surprising that Faraday knew the concept of denaturation.
And as everyone knows.
X-rays and ultraviolet rays are very energetic and can easily damage fats and proteins under long-term exposure.
In Xu Yunlai's later generations, some people liked to raise exotic animals.
For example, the red dragon centipede is twenty centimeters long, and the spider is about the size of a palm, etc.
Even cockroaches like Dubya and Cherry are kept by people...
There are also some people who like to raise ants, such as native, Huangqiong, Xiaoyueben, etc.
One way to identify whether the queen ant has laid viable eggs is to turn off the lights and shine a UV lamp on the eggs for a few seconds.
baimengshu.
The protein of insect eggs is extremely sensitive to ultraviolet light and will soon squirm, so the activity of the eggs can be determined.
This is also one of the intuitive evidences of the properties of high-energy rays on proteins.
Eel is a typical high-protein fish.
On average, every 100 grams of eel contains 18.6 grams of high-quality protein.
In addition, the liver of eels also contains a large amount of fat. In later generations, there was a health product called cod liver oil, which is a fatty oil extracted from the liver of fish.
Although most of the fish used to extract cod liver oil in later generations is cod, there is also a lot of fat in eel liver.
Therefore, under X-ray exposure for up to fifteen minutes.
The eel bones were successfully displayed on the film, and the proteins and liver at its main irradiation points were also denatured.
Then Gauss paused, pointed to the film not far away and said:
"Based on the situation of eels, the exposure time of fifteen minutes is obviously too long - at least if we want to successfully apply this ray to the human body, we must reduce the exposure time of the film."
Faraday followed Gauss's gaze and looked at the film, and nodded in agreement:
"Indeed, the exposure time of fifteen minutes is indeed a bit long, but it seems that fast-exposure films have not been released yet..."
Speaking of which.
Faraday suddenly thought of something, blinked, and turned to look at Xu Yun.
"...."
Xu Yun looked at him with an innocent expression and asked cutely:
"What's the matter, Professor Faraday?o(*≧▽≦)ツ"
Faraday looked at him deeply and asked aloud:
"Classmate Luo Feng, I wonder if Mr. Feiyu has left any manuscripts related to the negatives..."
As a result, before he finished speaking, Xu Yun interrupted him:
"Sorry, Professor Faraday, our ancestors did not leave any manuscripts about the negatives."
This chapter is not finished yet, please click on the next page to continue reading the exciting content! Faraday was still unwilling to give in and continued to ask:
"Really? I can trade Friedrich's manuscript with you!"
Gauss on the side: "??"
However, to Faraday's disappointment, Xu Yun still shook his head:
"Really not."
Then Xu Yun paused and explained:
"Professor Faraday, don't forget, the camera was only invented in 1839."
"No matter how talented our ancestors were, they couldn't have studied the film before the advent of cameras. Do you think so?"
"This is not a problem of technology or ability, but a difference of the times, which cannot be solved by manpower."
When Faraday heard this, he blinked quickly.
This seems to be the truth...
So he sighed with regret, a trace of disappointment flashed in his eyes.
Looking at Faraday, who was in a somewhat depressed mood, Xu Yun couldn't help opening his mouth, but in the end he remained silent.
After all, it follows the normal historical trajectory.
Just one more year...that is, 1851.
A photographer named Frederick Scott Archer would invent the collodion wet plate photography method.
Its principle is to mix collodion containing bromide, iodide and diluted with ether and apply it evenly on the glass. The glass plate is immersed in silver nitrate solution to form a sensitive silver iodide photosensitive layer.
Then take it out from the silver nitrate and quickly complete the exposure while the photosensitive layer of the collodion is still wet.
This exposure method only takes 15 seconds to half a minute and has been the leader in the photography industry for more than 30 years.
Of course.
Seeing this, some students may ask:
No, then why didn’t Roentgen use this method?
The answer is simple.
Roentgen actually tried the wet plate photography method, but in the end the development was not successful, so he could only continue to use the ancient daguerreotype method.
But what he didn't know was.
In fact, as long as he removes the ether link, X-rays can eventually be imaged on the film...
However, this step seems simple, but in fact it has troubled the photography industry for fifty years.
Of course.
For Xu Yun, who traveled through time in later generations, this question was an extremely simple matter.
Therefore, rather than doing something to attract attention at this time, it is better to follow the trend of history and wait for Archer's invention to appear.
At that time, he only needs to pretend to accidentally add less ether, and he can successfully resolve this barrier.
And at this time, he...
Just make it a mascot.
After all, his presence in front of Faraday and others seems to be a bit high-profile now - although a large part of it is due to Wheat's two attacks.
However, Faraday did not know the future direction, so he could only sigh quietly:
"Hey, the film..."
He never expected it.
At this point, the issue of film exposure has actually become a stumbling block.
But many times scientific research is just like this.
Accuracy issues often become a fetter that limits your progress.
This was true in 1850, and it will be true in 2022 - the latter will be even more cruel.
In fact, for Faraday and the others, today's harvest can be regarded as a fruitful return.
Then Faraday led everyone to the operating table, ready to pack up the equipment and call it a day - Kirchhoff had bought two fish earlier, and the remaining one was just right for lunch.
Xu Yun, Xiaomai Riemann and others had been working on the atmosphere team all morning, so naturally they were very sensible and wanted to help.
Mai and Riemann were responsible for packing the coils, while Xu Yun handled the vases and negatives.
But just when Xu Yun picked up the vase.
Suddenly, a voice came to his ears that made his heart tremble:
