Into Unscientific Chapter 149

  Chapter 149 Li Qingzhao whose painting style has completely collapsed (6K)

   From a domain perspective.

  Although the Song Dynasty in 1100 had not yet established a complete scientific training system, let alone the so-called scientific research literacy.

  But it is in this relatively ignorant and chaotic era.

  Old Su still made the most suitable choice the first time he observed the appearance of the cells:

   Rubbing patterns.

no way.

   After all, in the past few decades.

  Whether it is drawing star maps, compiling "Ben Cao Tu Jing" or writing "Xin Yi Xiang Fa Yao", diagrams are an indispensable core link.

  In terms of JOJO memes of later generations.

   Draw a picture.

   This is already an instinct engraved in Lao Su's DNA.

   After a quarter of an hour.

  Xie Lao Duguan returned to the courtyard with a small box, and handed it to Lao Su:

   "Master, here comes the pen and paper."

  Old Su nodded and took the pen and paper.

   While instructing Mr. Xie to take care of the ink, he spread the paper on the stone table. .

  Due to the relatively short schedule, Xu Yun hasn't had time to rub the ballpoint pen these days.

  So Lao Su can only use a fine-point brush this time. Compared with a ballpoint pen, drawing is a little more difficult.

  However, from the official to the prime minister, the old Su is still very solid in terms of culture.

  For example, in "Xin Yi Xiang Fa Yao", there are many pictures by him, which is much higher than Maverick's soul painter.

   He stared at the magnifying glass for a few moments, then left the eyepiece, and began to draw on the paper with a fine pen.

   After drawing a few strokes, I returned to the magnifying glass again, and repeated this many times.

  Xu Yun and others didn't say much when they saw this.

   He didn't even complain that Lao Su occupied resources by himself, asking him to step aside or something.

  In terms of Lao Su's status, even if he tinkered with the microscope all night alone, it was nothing.

that's it.

   Half an hour passed in a blink of an eye.

   Half an hour later.

  Lao Su put down the brush, exhaled a little tiredly, and a little sweat was faintly visible on his forehead.

  I saw that the drawing paper in front of him was filled with a large number of weird shapes.

   There are rectangle, square, ellipse.

   There are also long strips and triangles similar to tadpoles, and weird special shapes like mutant neon people, etc.

  Afterwards, Old Su took a breath, and took a teacup from the hand of Old Duguan Xie beside him.

   Taking a sip, he gave up his seat to Xiao Li who couldn't wait.

  He himself picked up the drawing paper and blew it, and asked Xu Yun:

   "Xiao Wang, many particles in the microscope have already been drawn on paper. Are these particles microbes?"

  Xu Yun thought for a while, shook his head and said:

   "Strictly speaking, your sentence is only about 70% correct."

  Then he glanced at Lao Su who had a face of "Why is it only 70%", and continued to explain:

   "Master, there are many types of particles in the dung water, hundreds or even thousands of types may be possible.

   For example, there are muscle fibers, red blood cells, white blood cells, Campylobacter, E. coli, yeast, and so on. "

  He walked to the edge of the drawing, pointed to one of the larger particles and said:

   "This substance is starch granules, which, together with muscle fibers and fat, are one of the normal metabolites in feces.

   Hmm. But the number of particles in this sample seems to be a bit too much.

   It is estimated that the donkey's stomach may not be very good. You can let it do more work and exercise its stomach.

all in all.

  These starch granules cannot be regarded as life, but matter. "

  Old Su nodded his head half-understood, the concept of matter was introduced by Xu Yun when he was in Allicin:

"I see."

   Then Xu Yun moved his finger and pointed to another small dot.

  Although the images drawn by Lao Su are not colored, it is easy to distinguish its origin from the quantity and appearance:

   "This is a white blood cell, a type of cell commonly found in animals.

  According to the handwriting of Fenglingyue Shadow Sect, this cell is a key protective barrier in the human body, and can swallow some sick bodies.

   But if the amount is too much, it may also cause a blood disorder.

  Patients suffering from this disease often have fever all over the body, and blood oozes easily from all parts of the body, and it is difficult to cure with medicine."

  emia.

   It is also a kind of saying of ancient leukemia.

Of course.

  Due to cognitive problems, ancient medicine basically classified all blood-related diseases into blood disorders.

   Strictly speaking.

   Leukemia and blood disease belong to the relationship between subsets and collections, and cannot be equivalent.

  But Xu Yun didn't deliberately correct this point, after all, it's better for Lao Su or his descendants to discover some concepts by themselves.

  Anyway, with the artifact of the microscope, the development of future medicine can be predicted with the naked eye—at least in the short term.

   It is only a matter of time before symptoms such as leukemia and bacteremia are discovered and classified.

   While Lao Su was trying to accept these concepts.

  Wang Yue, who was always silent on the side, looked at Tuo Tu, his cheeks twitched twice, and he couldn't help interrupting:

   "Xiao Wang, according to what you said, there are a lot of pathogenic bacteria in the feces, right?"

  Xu Yun nodded:

   "Yes, feces can be regarded as the living substances with the highest number of pathogenic bacteria."

  Wang Yue asked again:

   "" Then Xiao Wang, what kind of bacteria caused the disease that Wang contracted back then? available on the map? "

  Wang Yue never took his eyes off the drawing paper when he spoke, wishing to pull that germ out of it and fight with it for 300 rounds.

  Xu Yun couldn't help being dumbfounded when he saw this, and explained aloud:

   "Lord Zhonghou, what you got back then was bacteremia, and there are many possible pathogenic bacteria.

   But if nothing else, there is a high probability that it is some kind of Gram-positive bacteria, such as it and it. "

  Students who have studied medicine or biology in college should know.

  Bacteria can be divided into Gram-positive bacteria and Gram-negative bacteria by Gram staining.

  After the former is stained, the bacterial cells still retain the blue-purple color of the first dyed crystal violet.

  After the latter is stained, the bacterial cells lose the color of the initial crystal violet, and take on a complex saffron or sand yellow red.

   As for the difference between the two bacteria is also obvious:

  Positive bacteria produce exotoxin, and negative bacteria produce endotoxin.

   Therefore, Gram-positive bacteria generally cause purulent lesions.

  Among them, the typical ones are the bacteremia that Wang Yue suffered at the beginning, and the sepsis that will inevitably appear in the normal trajectory.

  As for negative bacteria, although they can also cause bacteremia and sepsis, they usually appear in the abdomen, biliary tract and hissing tract.

Of course.

  The two types of bacteria need to be stained by Gram staining when they are classified. It is not difficult to see certain types of bacteria under a high-power microscope.

   Then Xu Yun pointed to several bacteria with obvious appearance, such as staphylococcus and streptococcus.

  The shape is basically recognizable at a glance.

   After all, although Lao Su draws very seriously, hand-painting is hand-painting after all, and the degree of restoration is an unavoidable problem.

  Especially compared with the images of later generations, the images painted by Lao Su are indeed not clear enough, so we can only give priority to the introduction of bacteria with obvious characteristics.

anyway.

  If you have a chance, you can make a pencil and develop a sketch.

   After all, compared with traditional ink painting, the degree of restoration of sketch painting is obviously much higher.

  If the skills are exquisite, the picture quality may even be infinitely close to the restoration.

   "Staphylococcus."

  Wang Yue repeated the noun, staring at the image on the drawing for a while.

  As if to burn it in my heart.

   then turned his head.

   He exchanged a glance with his younger brother.

  Although they are only military generals, their vision is limited, unlike Old Su's mastery.

   It is even more impossible to judge the value of microscopes from the perspective of the times.

  But as witnesses of bacteremia and front-line generals, they are very clear about one thing:

  Dung water is an almost irresistible ultimate killer on the battlefield.

  During encounters, feces are often wiped on swords, guns or arrows, and the effect is stronger than many poisons.

  The enemy is basically certain to die, and in the best and best case, he will become a disabled person after recovering from illness.

  In the battle of defending the city, the defender will heat up the excrement and urine in a pot, and fall down with the rolling stone.

   There are many high temperature resistant bacteria in feces and urine, which can survive for more than 30 seconds under Baidu, and some will continue to exist in the form of spores.

  Thus, those in the middle will be scalded first, and then have a festering attack. It is a miracle that one out of ten people can survive.

   This dung weapon also has a very famous name:

  Gold juice.

   By the way.

  Gold juice, this is also one of the special weapons in the history of Chinese civilization.

   Most of the asphalt is used in Europe, the purpose is to scald the enemy through the heat conduction of the iron armor, without subsequent biological damage.

all in all.

  If the Bureau of Military Weapons can further explore the characteristics of E. coli through a microscope, maybe better drugs can be prepared!

   After all, although the effect of allicin is excellent, its storage time is still too short.

   Occasionally, it is okay for emergency response, but it is difficult to achieve large-scale popularization and emergency use.

  If the imperial court can develop more efficient drugs, it may even have an important and even decisive impact on the battle situation on the Western Front!

   Then Xu Yun became a teacher again, and briefly introduced some basic concepts to Lao Su and others.

  And the same as when making the lens before, he chose to play dumb again for some concepts.

   Either the manuscript has been lost, or even Feng Lingyue Shadow Sect didn't study it too deeply.

  As for the deeper observation inside the cell.

  He is going to go again in two days.

  One is that knowledge is too much to chew, and too much indoctrination at once will not necessarily result in good results.

  Secondly, the internal observation of cells also requires some dyes, and the preparation also takes time.

  The staining agents of later generations generally use acetate carmine or gentian violet, but in fact hematoxylin is also a good staining agent.

   More critically.

  Hematoxylin does not require sophisticated equipment, just find the materials.

  Its precursor component is called hematoxylin, which is extracted from the trunk of logan.

  Hematoxylin is oxidized to form hematoxylin, which can be used as a dye.

  The parts with more DNA and RNA in the cell can be stained blue with hematoxylin, which will be much easier to observe and interpret.

   And the other side.

   After getting off the microscope.

  Xiao Li quietly pulled Xu Yun aside, and said mysteriously:

   "Wang Lin, I want to ask you something."

  Xu Yun blinked:

   "What's the matter?"

  Xiao Li looked around a few times and asked:

   "Let me ask you, how much did you spend on this microscope?"

   "How much silver?"

  Hearing what Xiao Li said, Xu Yun was taken aback for a moment.

  What is this little bean sprouts asking Yinzi for?

   But doubts belong to doubts, he still touched his head, and answered truthfully:

   "The material is about one hundred yuan, if it is not silver-plated, maybe it can be reduced to less than one hundred?

  But it's hard to say if the labor cost is included, the price of asking Master Qi to sell it should not be very low. "

  In fact, from an objective point of view.

  The most valuable part of the microscope should actually be the calculation of curvature, which can even be regarded as a technical barrier.

  However, when Xu Yun estimated, he subconsciously omitted his contribution.

   After all, from the perspective of future generations, he just did a little work, and it would be good if he didn't get another expert.

  Xiao Li nodded thoughtfully and said:

   "I've heard about Master Qi's craftsmanship. Last year, there was a chamber of commerce in Hebei Road that reforged water wheels, and they hired Master Qi at a high price.

  The president of that chamber of commerce is my father's classmate, and I vaguely heard from him when I visited the house in the past few years, that Master Qi's salary is almost three times a day, and there are miscellaneous things, etc.”

  Xiao Li held his fingers and counted for a while, and finally said:

   "In other words, the cost of a microscope is about 150 yuan?"

  Xu Yun thought for a while, then nodded:

   "About this number."

  Xiao Li stopped talking after hearing the words.

   After a while.

   Just as Xu Yun was thinking about whether to speak, Xiao Li seemed to have made up his mind and asked:

   "Wang Lin, if I can spend two hundred coins, can you design another microscope?"

  Xu Yun was taken aback for a moment:

"Clam?"

   Seeing the surprise on his face, Xiao Li gently nudged the people who were watching the microscope with his chin, and explained:

   "Wang Lin, the microscope earlier was poorly crafted and not worth much, so I had the audacity to ask Uncle Su to take it home.

   But this microscope is expensive, and it would be too impolite to ask for it for nothing.

   But if I share this mirror with others, not to mention the complicated daily exchanges, it is impossible for me to use this mirror every day.”

  Looking at Xiao Li who was babbling about a bunch of reasons, Xu Yun's expression became more and more subtle.

  Mom!

  The painting style of Lay Yi An is not only getting more and more crooked now, it seems that the tmd is still unable to hold back, what should I do?

   Continue to develop like this.

  In the future, the Yi'an layman may have to be changed to the imamamycin layman

  If the fans of Xiao Li in the future knew about this, he would probably be hanged and beaten

   But soon.

  In Xu Yun's mind, the image of Xiao Li tinkering with the microscope appeared again.

  As a researcher of later generations, Xu Yun is very clear about one thing:

  Scientific research talent is actually a very mysterious but real honey attribute.

   Some people don't know anything about physics, but they are well-organized in conducting biological experiments, and their efficiency is several times that of others.

   Judging from Xiao Li's current mastery of biological concepts.

   Not to mention that she has 100% biological scientific research talent, at least the relevant probability is not too low.

  If she is really provided with enough resources, coupled with Xiao Li's background and the relatively high social tolerance of women in the Northern Song Dynasty.

  Bao Buqi, is it really possible for this girl to become the Grandma Tu of the Song Dynasty?

  Think here.

  Xu Yun couldn't help looking at Xiao Li, and pondered:

   "Miss Li, it's not difficult to design a microscope. I'll just redesign the radius of curvature, but what about the master?"

  Xiao Li heard the string song and knew the elegant meaning, and quickly said:

   "There's no problem with Uncle Su. I've snooped on him yesterday. If it wasn't for that, I wouldn't have come to find you first."

  Xu Yun nodded:

   "That's no problem, but Miss Li, this money is not a small amount, you"

   "You can rest assured."

   Before he could finish speaking, Xiao Li, whose eyes were shining because he was looking forward to the microscope, waved his small fist at him, and said in an incomparable way:

  "I just wrote three poems a few days ago, and originally planned to surprise my father with a nickname at the moon worship lantern festival in August and a half.

  But now I have changed my mind. After all, the lamp can write words. How can it be interesting to look at a microscope?

  So I'm going to sell them to Huafang in the city. With my current reputation, it's not difficult to sell them for two hundred coins, not to mention three poems. "

  Xu Yun:

Note:

  On the last day of the month, ask for a monthly pass.

   An-225 is gone, what a pity

   Push this friend's book, "Father Han Gaozu" by Lao Langju. When I picked up a copy of Three Kingdoms, I read it for several nights. The old author, the quality is guaranteed, and the key is also very rigorous...~
