Accompany Da Vinci's Super God Day

The heart is really a small one, as big as a fist.

It's located just below the middle left of the ribcage and has a smooth surface.

Thanks to the good natural ventilation in the basement, otherwise I would be fainted just by the smell.

The coffin itself is well sealed, no insects or anything can get in.

Heidi herself had the courage to do these things. While explaining to him what the lungs are and what they are used for, she took out the heart intact.

Da Vinci didn't know this crop very well, and asked while drawing the pattern: "And then? Why are there four chambers?"

They all know that a person will die without a heart, but what exactly does the heart do and how does it work? In fact, their minds are blank.

"So." Heidi deliberately kept the main blood vessels coming in and out, fetched a glass of water, and poured the water into it in front of him.

The left and right atria do not communicate with each other, and the left and right ventricles cannot communicate with each other.

That handful of clear water flowed from the atrium into the ventricle, but it couldn't flow back.

"Why is this again?"

"Because of the valves."

Heidi originally thought that she came to the Ducale Palace to be an alchemist, but she didn't expect to go to the basement to take an anatomy class with Da Vinci by lighting candles.

This ordeal lasted from the afternoon to midnight, and a servant came to deliver the meal in the middle.

——People put down the food and ran away after a long distance, but only Da Vinci could eat it.

After explaining the general function of the heart, he also had to explain what is the sternocleidomastoid muscle, where are the main veins and the spine. Although what was said was actually just modern common sense, it also made Da Vinci fill a whole notebook.

Heidi searched for the knowledge she had learned when she was studying, and was tired and hungry at the end of the talk.

She's been through the wars, the games of power and politics, and she's been around Hollywood's Vanity Fair for far too long.

A living person is more frightening than a dead body.

"You continue to study, I went back to the house to rest."

She washed her hands by the side, and suddenly remembered something, turned to him and said, "After you send this body back to the grave, remember to wash your hands first."

"why?"

Heidi froze for a moment, subconsciously said: "Don't you know why you wash your hands?"

Da Vinci was also at a loss: "If there is something dirty, just wipe it off."

generation gap.

This is the generation gap her granddaughter has mentioned before.

Heidi wanted to muddle the subject, but felt something was wrong.

"I remember, Florence had a caesarean section now, right?"

She went to the party at Christmas and was relieved to hear the gossip of the women.

But now that I think about it, this matter is simply terrifying.

Da Vinci was waiting to hear her explanation, but she suddenly brought up another question: "Yes? What's wrong?"

When she cut open her heart just now, she didn't feel too much fear and panic.

But when I heard this sentence, I shuddered inside.

"Those doctors, don't they wash their hands when delivering babies?"

"So why wash your hands?"

"Is the death rate high?"

"...It's very high. The traditional method of delivery is still basically used now. When there is really no other way, a caesarean section will be chosen."

Da Vinci was originally studying which muscles were changing when the palms were opened and closed. At this moment, he stopped the movement of his hands and turned to look at her: "What's going on?"

Heidi had unknowingly washed her hands four or five times. She took a deep breath and warned, "Don't tell me about this right now. I'll tell you in two days."

Penicillin can be put aside for a while, and other things can also be temporarily put aside.

She wants to make the microscope first.

Only when people know the concept of microorganisms can they further understand viruses and bacteria and understand all aspects of knowledge.

Right now, she has been paid a month's salary in advance, and she is finally allowed to leave the palace. The next morning, she took the blueprints and went to the optical shop on Square West Street.

Italy's glass manufacturing technology is quite excellent, and it was famous all over the world until hundreds of years later.

With the advancement of craftsmanship, more and more mosaic decorative glass has been replaced in the church, allowing the sun to cast different light and shadows.

People in this era like to wear single lenses, thinking that it is a symbol of status and elegance.

As long as you find a suitable lens and a flexible enough frame, you can restore a similar microscope.

"what is this?"

When the craftsman took over the blueprint, he was obviously a little surprised.

There is a '【'-shaped strange thing drawn on the drawing, with a wooden strip in the middle that can adjust the distance, and two lenses in the upper and middle parts.

"This is the meaning of Master Medici." Heidi said briefly, paid him the deposit, and only quickly ordered the delivery period and specific requirements, then turned and left.

Say too many mistakes, don't explain other things.

Taking advantage of the time she came out, she took the maid around for a while.

Florence is too big, and the houses are arranged in a square shape. In fact, it is not easy to know the way.

When she was Da Vinci's maid in the past, she only dared to wander around a few streets nearby, and it took her a long time to find her way to the suburbs.

Now that I have more Dejo by my side, it is actually a good thing for her to act as Medici's eyeliner to monitor me, after all, we must make full use of any conditions.

The Church of the Holy Cross and the Cathedral of the Flowers are east and north, the Arno River is wide and long in the south, and the Royal Palace of Ducale is in the north.

Going further north from the Ducale Palace, about 500 meters away, is the historic Florence Academy.

Dejo obviously didn't know why she came to such a place, and only pointed to the guard at the door.

Women can't come to this kind of place casually, let alone go in for training.

Heidi only looked at the university from a distance across the street, and asked after a while, "What are they studying in the university now?"

"I heard from people in the palace that there are civil law, religion, literature, and there seems to be pharmacy." De Qiao said uncertainly: "If you really want to go and see, I can ask the adults for instructions."

"no need."

She might be the smartest person in Florence right now.

They stayed in the street for a while, then turned back to the palace.

I heard the servants said that Da Vinci sent the corpse back overnight, and set up a new cross and flowers for the poor man.

Heidi originally wanted to chat with him, but when she turned her head, she saw Dejo brought back the cleaned glass dishes.

That's right - an experiment that wasn't done before!

All the moldy and hairy ones were scraped off and thrown away. It took her a long time to explain to those people that it wasn't some evil witchcraft.

Now that I have helpers at hand, many things are much easier to handle.

Moldy orange peel, a spoonful of thinner beef broth, and the pus scraped from the inflamed wounds of patients in the hospital.

All it takes is one command.

De Qiao stood by with a suspicious expression on his face, obviously still a little worried.

Heidi mixed the agar powder with the beef broth in front of her, and waited for it to set into a jelly after mixing well.

The experiment now is to confirm the lytic effect of Penicillium on the bacteria after culturing Penicillium and Staphylococcus aureus.

If the colonies of Penicillium continued to expand and Staphylococcus aureus decreased in the Petri dish, she could confirm that the colonies in the glass dish were the life-saver she needed.

——But it doesn't seem to be enough to just toss around like this.

After Heidi finished two or three petri dishes, she belatedly realized a problem.

How to kill other colonies in this petri dish first?

If she cultivated it for a long time, the glass dish was filled with other irrelevant colonies, it would be a waste of effort.

This culture medium must be sterilized first and then sealed, but obviously it cannot be scalded with boiling water.

alcohol?

No alcohol either...wine doesn't seem to work.

De Qiao watched from the side as she suddenly froze in the middle of her work, thinking that she was bewitched, so he cautiously reached out and poked her.

Heidi came back to her senses and subconsciously asked, "Do you have a steamer?"

It won't work to scald directly with boiling water, but it should be done with high-temperature steam.

So the maid followed her to the kitchen again.

The three servings of beef soup have turned into jelly, and they are put into a steamer and steamed with boiling water for 10 to [-] minutes. After they come out, they are immediately covered and sealed.

Three petri dishes, one for the mold on the orange peel, one for the pus, and the third for storage in a cool, clean place, until the first two colonies are cultured before proceeding to the next step.

After Heidi finished her work, she took the time to visit Da Vinci again.

The place where she lives is really far away from him. Although she spent seventy or eighty euros to visit here in her previous life, she still can't recognize the way now that she really lives in the palace.

In this gap, she caught a glimpse of many beautiful and beautiful paintings, and vaguely heard the melodious sound of a violin.

Da Vinci was sitting on a wicker chair in the backyard, looking through a contract.

As soon as he heard the sound of footsteps, he knew that Heidi was coming, so he waved his hand and said, "I've washed my hands three times."

Heidi raised her eyebrows lightly, and nodded in approval.

"What are you studying?"

"The monastery's contract." Da Vinci stroked his chin and said, "This is a bit of a test of my math ability."

Although he is now a painter sponsored by the Medici family, this status only gives him a fixed residence and investment.

Just like Botticelli, he can still run a studio independently and receive orders for various sculptures, portraits and even bronze statues.

Mr. Piero da Vinci came to him today, still carrying two chickens bribed by the monastery for this contract.

As long as he signed it, he would help decorate the clock face of the monastery, plus draw a whole "Doctor Comes to Worship".

"This contract sounds pretty good," Da Vinci raised his eyebrows, picked up a pen and was about to sign the contract.

"Wait—" Heidi reached out and took the contract, obviously worried: "I'll read it first."

The former employer expressed some dissatisfaction: "I understand very well."

Heidi silently read all the terms, and frowned at him.

"Which line do you see—it's not wrong??"

The author has something to say: Da Vinci: Ha OAO?

Heidi: You are really going to be sold by your own stupidity...

【January 1, manuscript deposit notes】

What exactly did the medieval aristocratic etiquette look like that has been misunderstood by everyone for many years?

Source: Baima Aesthetics

Misconception [-]: Paying homage to each other is only for acquaintances.

In fact, no matter if they are acquaintances, strangers or enemies, salute is required.

Women usually hold up skirts with both hands, knees slightly squat and nod at the same time, while men hold their right chest with their left hands, take off their hats with their right hands and bow slightly in salute.

Etiquette on horseback: Both parties are on horseback, the men's etiquette remains the same, and the women only need to nod to salute.As long as a man is wearing armor, he doesn’t have to take off his hat and put his hands on his chest. If he doesn’t wear armor, he should immediately dismount and salute when he sees a man or woman with a higher title than himself. You can see the two young men in the movie "Cinderella" When they met for the first time, the prince didn't wear armor, and Cinderella didn't know the identity of the prince. They just nodded and saluted each other.

This is probably because wearing armor is cumbersome and inconvenient to get on and off the horse and bowing down to salute, while the man wearing the armor represents the strength of the country and bears the honor of going out for the country.

Misunderstanding [-]: All unconvinced men can meet for a duel.

First of all, only men of the two classes of aristocrats and priests have the right to initiate a duel, and those of a higher class cannot challenge those of a lower class (such as the industrial, peasant and commercial class without titles) to a duel.Nobles cannot challenge priests to duels, but priests can challenge nobles to duels; secondly, duels are conditional.

When there is a dispute between men, you must first give the other party a chance to explain satisfactorily. If the other party touches your heart or realizes his mistake and apologizes to you, you cannot duel. If the other party speaks rudely or the explanation does not satisfy you, you Only then can a duel be proposed.

Third, both sides must use the same weapons. As long as one side is unable to fight or voluntarily gives up, the other side will win, and there is no need to fight to the death.But the general nobles or priests are more concerned about face and family reputation, and they will fight until the moment before they fall.

Myth #[-]: Medieval men often kissed women's hands.In fact, the etiquette in the Middle Ages is that a man’s mouth is not allowed to kiss a woman’s hand casually. Only nobles can kneel and kiss the hands of the king and queen. The king and nobles will also kiss the hands of the bishop, but the kiss is the bishop. The big gemstone ring on the left hand represents the status of the bishop.

Not all occasions give priority to women. For example, in church services, admission is in order of knighthood. For people with the same knighthood, men prefer women, and old people give priority to young people.

Men are obliged to hold holy water for any woman, and women can go out first when they go out at the end of the service.So not all men in the movies we see will kiss the back of the woman's hand first when they see a woman.Ordinary people were not allowed to kiss hands in the Middle Ages.

(But the small barrel in this article is considered a very special existence in the Medici family + the personality is relatively outgoing and unrestrained.)

Misunderstanding [-]: Nobles cannot carry weapons when they invite guests to dinner, nor can they talk to each other.

Medieval nobles often held various banquets and invited friends to attend. Neither the host nor the guests would wear armor. Wearing armor means that the place to eat is not safe, and it is always necessary to prevent the invasion of assassins and enemies.

However, both the host and the guests can eat with weapons. They can discuss business or chat and sing while eating and drinking. The higher the interest of the guests, the more successful the banquet held by the host, and the higher the satisfaction of everyone with the banquet.However, guests are not allowed to quarrel and make trouble during the meal, no matter who is right or wrong, please come out of the scene.

Therefore, the aristocrats do not eat elegant and crepe-like delicacies, nor do they sip alcohol. Generally, guests drink up after toasting to express their gratitude to the host.Before going out after eating, a full set of etiquette and etiquette should be performed to thank the host.
