Into Unscientific Chapter 302

  Chapter 302 Octopus I have suffered pressure that I shouldn't have (6.4K)

   Ten minutes after image exposure.

  The eel that Kirchhoff bought back had been disembowelled, with its head drooping and hanging aside, with a strange light shining in its eyes.

  Riemann took the ring taken out of the belly of the fish and went to the faucet to clean it a few times.

   Wait until the blood and stains are cleaned.

   Riemann pinched the ring with his index finger and thumb, put it in front of his eyebrows and looked at it, and said to Gauss:

   "Teacher, this is a metal ring. It seems to be made of silver. There are words engraved on it."

   Gauss glanced up at him, put down the water glass in his hand, and asked:

   "What is written? Great Chuxing King Chen Sheng or the Supreme Lord of the Rings?"

   Riemann looked at it for a while, and finally shook his head:

   "The words are too blurry to read clearly."

  Gauss didn't pay much attention to this, but turned his head and asked Faraday:

   "Michael, it really is a metal ring. By the way, how did you think that the ray could take such an image?"

  Faraday heard the words, 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 tried just now?"

  Gauss was taken aback when he heard the words, but quickly replied:

"of course I remember."

  Faraday stood up, beckoned everyone to follow him to the console, pointed to the tried metal and said:

   "Look, steel plates are completely light-blocking, wood boards and books are completely light-transmitting, and thin aluminum sheets are 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 mixed with other substances at the same time?"

   "The answer is yes, it is."

   As he spoke, he looked around, pointed to Gauss and the others with a smile, then pointed to the fish, and said:

   "Vertebrate!"

  Gauss was silent for a moment when he heard the words, after a little thought, a word came out of his mouth:

"calcium?"

   "Bingo!"

   Faraday snapped his fingers in a rare way, and it can be seen that the electrician is a little excited at this time:

   "It's calcium!"

  Speaking of the substance calcium, many people subconsciously think of calcium carbonate.

   is the main component of limestone and marble.

  On this basis, some people will regard calcium as stone foam, thus creating the illusion of non-metal.

   But actually.

   It is not difficult to see from the gold lettering it contains.

   Calcium is not a non-metal, but a metal element.

  It is located in the 4th period, group IIA in the periodic table of chemical elements, and it is a silver-white crystal at room temperature.

   One of the most abundant metal elements in the human body is calcium.

at the same time.

  The discoverer of calcium is none other than Humphrey David who guided Faraday:

  In May 1808.

  David mixed wet quicklime and mercury oxide in a ratio of 3 to 1, placed it on a platinum sheet, and connected it to the positive electrode of the battery.

   Then make a depression in the mixture, pour mercury, insert a platinum wire, and connect with the negative electrode of the battery, and obtain a relatively large amount of calcium amalgam.

   Then he distilled the calcium amalgam to obtain silver-white metallic calcium.

   And in the bones of the human body or vertebrates.

  Calcium mainly exists in bones and teeth in the form of crystals, accounting for 1.5% to 2% of the total weight of the human body. It is an extremely abundant mineral in the human body.

   So as David's second-in-command.

  Faraday naturally thought of the concept of bones after discovering that the mysterious rays had different penetration effects on different metals.

   But mentioned earlier.

  In the current timeline, the scientific community has a relatively deep understanding of the particle properties of light.

  They know that the particle flow will carry a lot of energy, and the energy may affect the human body.

  Like raindrops, hail, and sandstorms in the macroscopic world, it hurts when you hit your face.

  So after thinking about it, Faraday chose the eel as the experimental subject.

  Anyway, the eels have no objections, do they?

   Then Faraday put the negative on the table, and seriously analyzed it with everyone:

   "Look, the cranial and pharyngeal cranial arches are very obvious, and the image of the lingual arch is blurred."

   "In addition, the spine and ribs are also very clear"

   "This is the intermuscular bone under the fin, right? Such a small spine can be photographed 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:

   "According to the imaging results, the calcium in the bones seems to absorb this mysterious ray, and the internal organs will be passed through by it."

   "So after the same intensity of light 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 the animal body will affect the mysterious rays, it is temporarily unknown."

   "Presumably with everyone's IQ, it shouldn't be difficult to understand the meaning of this situation?"

   Following Gauss' words.

  The atmosphere in the laboratory was suddenly quiet, and a needle could be heard in an instant.

  The backgrounds of everyone present today are not ordinary, they are either the stable version of the boss, or the youth version of the future boss.

   So for them.

  The deep meaning of Gauss's words is not difficult to understand:

  This ray can visualize 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 area of ​​medicine, there is the possibility of breakthroughs in many difficult and miscellaneous diseases!

  For example, a fracture, for example, a tumor in the body, or for example, wanting to retrieve the bullet after being shot.

   This is undoubtedly an epoch-making discovery for modern medicine.

  In addition, its wavelength, frequency and other characteristics are bound to cause a big earthquake in physics!

  Think here.

   Standing beside Gauss, Weber couldn't help feeling deeply grateful while he was excited.

  He was glad that he did not miss such an experiment today.

  Today, whether it is the measurement of cathode rays, the calculation of the charge-to-mass ratio of particles composed of rays, or the discovery of unknown rays, any one of them has the status and value to be recorded in history.

  If this is the case with one, let alone the gathering of the three.

It can be said like this.

  Every one of these people at the scene today counts as one, and even the eel and the fish-selling fisherman will definitely be recorded in the history of physics.

   In a way.

  The achievement of everyone today is not to discover something, but to work together to open a door to a whole new world.

   Even just looking at the light coming out of the gate is enough to imagine the magnificence and vastness inside.

   Right now.

   Weber, a top electrician in the current world and even in the history of science, could not help but think of four words:

   How fortunate.

  Weber couldn't help looking at Gauss, rolled up his sleeves, and said excitedly:

   "Friedrich, since this is the case, let's try it with a human body, and I will be a volunteer!"

  However, Gauss waved his hand at him and stopped him:

   "Edward, don't worry, let me check something first."

   After speaking, he turned around and came to the sink where the eels were placed.

  This was originally a cleaning tank for chemical utensils, but now it is temporarily used as a shelter for eels.

   After coming to the pool.

  Gauss put on his gloves, picked up the knife that Riemann used to kill fish, and continued to dissect along the eel's abdomen.

   After two or three minutes.

  Looking at the scene in front of him, Gauss's breathing stagnated slightly, and he waved to Faraday and others:

   "Michael, come and have a look!"

   Seeing this, Faraday put down the negative, walked quickly to Gauss, and asked:

   "What happened, Friedrich?"

  Gauss took the cut eel to the platform of the sink, pointed at the edge of the knife and said:

   "Look."

   Faraday and others followed the trend.

  I saw this moment.

  On the belly of the eel that was cut open by Gauss, a small part of the meat that should have been pink and tender suddenly turned black!

   Then Gauss picked up the fish with a knife, exposing the fish liver below.

  Generally speaking.

  An eel will have a liver and a gallbladder. 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:

   "The protein and fat inside have gone bad?"

  Gauss took off his gloves with a solemn expression, turned on the tap and washed his hands, and replied at the same time:

   "That's right, if I'm not mistaken, that mysterious ray should be very destructive."

   "If it is irradiated for too long, the fat and protein in the body are likely to be severely denatured."

   "Fortunately, we were not in a hurry. We took this eel up for a try first. If you and I played in person, I am afraid that the human body will suffer some irreversible damage."

   Coincidentally.

  The nerve cells of the eel were not completely dead at this time, so it suddenly flapped its tail twice, which shocked everyone.

   At the corner that 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 well known.

  X-rays and ultraviolet rays have a lot of energy, and under long-term exposure, they can easily damage fats and proteins.

  In Xu Yunlai's later life, some people liked to raise exotic animals.

  For example, the red dragon centipede with a length of 20 centimeters, and a spider that is about the size of a palm, etc.

  Even cockroaches such as Dubia and Cherry are raised.

   There are also some people who like to raise ants, such as Yuan Yuan, Huang Qiong, Xiao Japan and so on.

  One way to identify whether the queen ant is laying live eggs is to turn off the light and shine a UV light on the eggs for a few seconds.

  The protein of the eggs is extremely sensitive to ultraviolet rays, and will soon produce wriggling, so that the activity of the eggs can be distinguished.

   This is also one of the intuitive evidences for the properties of high-energy rays on proteins.

   As for eel, it 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 eel also contains a lot of fat - there is a health product called cod liver oil in later generations, which is a kind of fatty oil extracted from fish liver.

  Although most of the fish that extract cod liver oil in later generations are cod, there is also a lot of fat in eel liver.

  So under X-ray exposure for up to fifteen minutes.

  The fish bone of the eel was successfully imaged on the negative film, and the protein and liver at the main irradiation point were also denatured.

   Then Gao paused, pointed to the film not far away and said:

   "According to the situation of the eels, the exposure time of fifteen minutes is obviously too long—at least to apply this ray to the human body smoothly, we must reduce the exposure time of the film."

  Faraday followed Gauss' gaze and looked at the film, and nodded in agreement:

   "Indeed, the exposure time of 15 minutes is indeed a bit long, but the negatives of the rapid exposure seem to 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 innocently, and asked with a cute face:

   "What's the matter, Professor Faraday? o(*≧▽≦)ツ"

  Faraday took a deep look at him, and asked aloud:

   "Student Luo Feng, I don't know if Mr. Fat Yu left any manuscripts related to negatives"

   As a result, Xu Yun interrupted him before he finished speaking:

   "Sorry, Professor Faraday, the ancestors did not leave any manuscripts about negatives."

   Faraday was still not reconciled, and continued to ask:

   "Really not? I can exchange 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 that the camera was invented in 1839."

   "No matter how powerful the ancestor of Fat Fish is, he couldn't have studied negatives before cameras appeared, do you think so?"

   "This is not a problem of technology or ability, but a difference of the times, which is beyond the reach of human beings."

  Faraday blinked quickly when he heard the words.

   Seems to be the truth.

  So he sighed with some regret, and a trace of disappointment flashed in his eyes.

  Looking at Faraday, who was a little depressed, Xu Yun couldn't help opening his mouth, but he still didn't speak in the end.

   After all, follow the normal historical trajectory.

   Just another year. That is, 1851.

  A videographer named Frederick Scott Archer would invent the collodion wet plate photography method.

   Its principle is to mix the collodion containing bromide, iodide and ether diluted and spread 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 of the silver nitrate, and quickly complete the exposure while the photosensitive layer of the collodion is still wet.

  The speed of this exposure method only needs 15 seconds to half a minute, and it has been the leader in the photography industry for more than 30 years.

Of course.

  Seeing this, some students may ask:

   No wow, then why didn't Roentgen use this method?

  The answer is simple.

  Rontgen actually tried the wet plate photography method, but in the end the imaging was not successful, so he could only continue to use the ancient daguerreotype method.

   But what he didn't know was.

  In fact, he only needs to remove the link of ether, and finally X-rays can be imaged on the film.

  However, this step seems simple, but it has actually troubled the photography industry for fifty years.

Of course.

  For Xu Yun, who traveled through later generations, this question was so simple that it couldn't be simpler.

  So instead of 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, as long as he pretends to accidentally add less ether, he can successfully resolve this barrier.

   And at this time, he

   Just need to be 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 ahhh.

   But Faraday didn't know the future direction, so he could only sigh faintly:

   "Hey, negatives"

   He never expected it.

  At this point, the exposure problem of negatives will actually become a stumbling block in front of us.

  However, scientific research is often like this.

  Accuracy problems often become shackles that restrain you from moving forward.

  As it was in 1850, so it will be in 2022—the latter will be even crueler.

  In fact, for Faraday and the others, today's harvest can be regarded as a rewarding experience.

   Then Faraday led the crowd 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 could just be used for lunch.

  Xu Yun, Mai Riemann and others made an atmosphere group in the morning, and naturally they were very knowledgeable and wanted to come up to help.

  Wheat 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 there was a voice in his ear that made his heart tremble:

   "Ah, this is also very strange"

Note:

   Can I have a monthly pass?
