Yang Pingfan and Li Lan were a little surprised, but Su Yu didn't say anything, and it was not easy for the two of them to ask what conflicts they had between the husband and wife.

Li Lan continued the topic just now, "But that gangster named Zixuan seems to have some background, he dares to blow up the stab in the experimental elementary school, directly kidnap people in broad daylight, and let the sisters and brothers go to school there, I'm afraid there will be trouble next." ”

Su Yu sneered, "What can I do if I go to an experimental primary school, my identity is still a bit convincing, and I will ask the education department to let him transfer tomorrow." ”

There are too many elements, it seems that being an ordinary person is just a pretense, Dr. Su is powerful.

Yang Pingfan heard something in Su Yu's words, and asked tentatively, "Dr. Su, what's going on between you and Liu Yuan?"

"It's nothing, it's a bit of a conflict of ideas with the child's father, don't mention it, eat vegetables, this Cantonese cuisine is famous. ”

Su Yu refused to elaborate, Yang Pingfan and his wife didn't want to ask much, during the banquet Su Yu asked about the purpose of the two of them returning to Suzaku, Yang Pingfan roughly said, Su Yu pondered, "If you need anything, just tell me, I can help if I can." ”

Yang Pingfan nodded and said no more.

——

After separating from Yang Pingfan and Li Lan, Zuo Ci first walked around the local area, logged on to the local life website, spent money to rent a secluded basement, bought a set of instruments and equipment, and then used spells to change a new image for himself.

During this period of modern society, Zuo Ci has figured out the aesthetic standards of modern people, and his current style fashion is a standard small fresh meat that integrates the image of a number of Internet celebrities, simply put, the face is white and beardless, the lips are red and the teeth are white, male and female, full of neutral colors, exuding feminine beauty.

With this appearance and a height of more than two meters, Zuo Ci easily blended into a nightclub, looking at the men and women on the dance floor who were crazy about the railing with the hot DJ, Zuo Ci ordered a glass of mojito, sipped it slowly, and waited for the prey to take the bait.

But it didn't take long for his eye-catching image to attract a lot of men and women who came up to talk, and the last genetically modified person with a height of two meters was favored by Zuo Ci and drove away the other partners, he was wearing a Little Red Riding Hood, full of manliness, and the modified person's body shape made it difficult for other competitors to retreat, shaking a glass of champagne in his hand, which was very eye-catching.

Zuo Ci glanced at it, "Drinking champagne in the bar is very tasteful." ”

Little Red Riding Hood couldn't hear the sarcasm in Zuo Ci's words, and was proud, "Champagne is not only a cold wine region in northern Gaul, but also the name of a class of sparkling wines, but not all sparkling wines are called champagne, according to local laws, only sparkling wine produced in Champagne can be called champagne." ”

"Oh, do you know how champagne is made?"

Zuo Ci took a sip, with a hint of provocation in his tone, and Little Red Riding Hood's eyes lit up, "Of course, I still have a lot of research on wine, but the Champagne region was a "ominous place" three or four hundred years ago.

At that time, every year in early spring, when the weather warms up, the wines bottled in the cellars of the Champagne region will explode like a curse and scare the winemakers out of their own way.

At that time, people were not aware of the existence of sparkling wine, and the Champagne region mainly used Pinot Noir grapes to make static red wines, however, the Champagne region in the north was not a good red wine region. Due to the cool climate, the grapes grown here are not too ripe to produce the full-bodied red wines of the Burgundy region.

What's even stranger is that the wines of the Champagne region always explode en masse when the following spring arrives.

Fortunately, due to the proximity of Champagne to the Seine, the geographical advantage made the sales and reputation of the wine here quite good, but the problem of the collective explosion of wine bottles still caused great distress to the local convent responsible for wine production.

Gradually, through investigation and summing up experience, people explored the cause of the collective explosion of wine bottles in the Champagne region:

When the temperature and oxygen content are right, the yeast will obtain the glucose in the grape juice and metabolize it into alcohol and carbon dioxide, and at the same time produce energy to maintain its own life activities, which is the principle of winemaking, in which carbon dioxide will be excreted in time as an additional product.

Fermentation is terminated when the yeast has exhausted all the glucose, and in the case of grape juices with a high sugar content, the yeast will continue fermentation until the alcohol content is too high, around 16%, and the yeast will be poisoned by the alcohol produced by its own metabolism, at which point the fermentation will also be terminated.

Once fermentation is terminated, the winemaker can further process the wine, bottle it, put it in the cellar, and wait for it to be sold or aged in the cellar.

However, in the cold Champagne region, the process does not go so smoothly.

After the onset of winter, the temperature in the Champagne region continues to drop. When the temperature drops to a certain level, the yeast pauses fermentation and enters a dormant-like state.

At this point, the winemaker mistakenly believes that fermentation has stopped, so he bottles the wine.

However, the wine at this time had both surviving yeast and residual glucose.

The following spring arrives, the weather warms up, and the yeast wakes up and begins fermentation again. At this point, the wine has been bottled and sealed, and the carbon dioxide produced by fermentation cannot be released, but can only accumulate in the bottle, and the air pressure inside the bottle continues to rise, and when it reaches a certain point, it will cause an explosion.

After figuring out the principle of the explosion, the winemaker only needs to grasp the degree and rhythm of fermentation, and then he can perfectly solve the problem of frying the bottle, and brew a still wine that does not explode the bottle and has no bubbles.

However, in the 17th century, before the Industrial Revolution began, it was not easy to strictly control the temperature and accurately monitor the degree of fermentation.

Instead of preventing bubbles from forming after bottling, the locals invented a method for making sparkling wine, the secondary fermentation method, and designed a stronger, less explosive bottle for sparkling wine, and sparkling wine was born.

So, how exactly is the second fermentation and how is the sparkling wine made?

First, at the end of the first fermentation, the winemaker gets the "base wine", to which a fermentation broth consisting of glucose syrup and yeast is added, and then the wine is sealed.

After the following year's warm-up, the yeast undergoes a secondary fermentation directly in the bottle, producing delicate carbon dioxide bubbles.

The selection of yeast varieties, the dosage control of sugars and the aging time are the key to the success of the secondary fermentation.

Winemakers generally choose specially cultivated yeast strains that can withstand high alcohol, high carbon dioxide concentrations, and high pressures of 5-6 atmospheres.

In order to prevent the fermentation temperature from being too high and the fermentation too fast to volatilize the resulting ester aromatic substances, the secondary fermentation of yeast strains can also achieve continuous fermentation at a lower temperature of 10-12 °C.

Secondly, the dosage of syrup added to the fermentation broth must also be strictly calculated, and if the sugar content is too low, the carbon dioxide produced will not be enough to achieve a satisfactory foaming effect, which will also affect the taste of the wine.

If the sugar content is too high, as the fermentation progresses, the air pressure in the bottle is too high, there is a risk of explosion, in addition to the above components, ammonium diphosphate needs to be added to the fermentation broth as a nitrogen source for the growth and reproduction of yeast.

Zuo Ci nodded, with a sudden realization and admiration on his face, "I didn't expect that there is such a scientific principle behind this fine wine, every kind of fine wine is really hard to come by." ”

Little Red Riding Hood beckoned, the bartender directly handed over a bottle of champagne, and Little Red Riding Hood poured a glass for Zuo Ci, "Taste this, taste the taste of history and science." ”

Zuo Ci drank the mojito and arched his hand, "Then thank you." As he spoke, he picked up his wine glass and drank half a glass, and burped.

Little Red Riding Hood secretly despised in his heart, saying that champagne is a fine taste, not like Zhu Bajie eating ginseng fruit without distinguishing the taste, and at the same time secretly happy, the cocktail itself has great stamina, you still drink it with champagne, wait a minute, I will definitely make you want to die.

Zuo Ci smacked his lips, the taste was not bad, much better than that Sprite, glanced at the wine bottle, and was immediately attracted by the strange-looking cork, "Hey, why is this cork different from what I saw before?"

Little Red Riding Hood explains with a smile, "Unlike ordinary wine corks, sparkling wine corks are mushroom-shaped, wide at the ends and narrow in the middle, but this is not its original shape, the champagne cork that has just been made is actually a standard cylindrical shape, composed of two parts from bottom to bottom, the outer part of the bottle is made of cork strips and cork chips, and the part that enters the bottle and touches the wine is made of two to three whole pieces of natural cork.

The porous and elastic cork disc absorbs the carbon dioxide in the bottle, expands slowly, and presses tightly together with the mouth of the bottle to maintain a stable air pressure inside the bottle and achieve a good sealing effect.

Once the champagne is opened, the cork tray filled with carbon dioxide naturally stretches and becomes large and wide.

The part of the cork bar in the middle that connects to the cork plate is tightly bound by the mouth of the bottle, and at the same time, this part hardly absorbs gas, so it becomes thinner and thinner, so that the champagne cork becomes a mushroom shape with two thick ends and a thin middle. ”

Zuo Ci showed an expression of adoration, and pointed to the metal mesh on the wooden stopper, "What's the use of this?"

Little Red Riding Hood said that you have so many problems, but the imminent movement of the third leg still made him patient to explain.

In addition to its cute mushroom-like shape, champagne corks are often covered with a layer of metal mesh.

This metal mesh is like a cage and a protective cover for the champagne stopper, which is used to prevent the air pressure inside the bottle from being too high, and the cork will suddenly erupt from the mouth of the bottle, causing danger.

Studies have shown that the speed of the champagne cork when it flies out after vigorous shaking can reach 40 kilometers per hour, and the pressure inside the champagne is about 5-6 atmospheres, and the pressure can be even greater if you add the effects of shaking during transportation.

In the early days, Gallic winemakers wore a mask made of wire mesh and gauze to prevent injury, and even in today's champagne-making process, champagne has a 3%-6% bottle explosion rate.

In addition to the stoppers and metal mesh, Champagne is also unique in its shape with thick walls, sloping shoulders and a sunken base.

This kind of bottle is fatter and stronger than ordinary wine bottles, with a gentle slope of the shoulder, a relatively large stopper, a stable bottle body as a whole, strong pressure-bearing capacity, and will not be blown up by the internal air pressure, and can also slow down the entry of oxygen and prolong the preservation time of wine.

In addition, the deep groove of the champagne base is not only designed to be stable, but it also better withstands the carbon dioxide pressure inside the bottle than a flat base, equalizing the air pressure and reducing the risk of breakage.

Zuo Ci sighed after hearing this, "I didn't expect that today's well-known champagne would originate from explosions. ”

Little Red Riding Hood also echoed: "In fact, many scientific inventions around us come from accidents, and only by observing carefully and daring to create can we get inspiration from accidents and create more beautiful things." ”

As he spoke, he put on an expression of looking up at the starry sky like constipation, as if he was a great philosopher of erudition.

A sneer appeared at the corner of Zuo Ci's mouth, shaking the empty wine glass, "Speaking of the history of champagne, I have another thing, the sense of time is a very strange thing, people in the past, some will think that the distance is very close, and some will feel a long time away, but they are people of the same era."

For example, in the year when Emperor Guangxu came to power, Nintendo was founded, and in the same year that Einstein published his special theory of relativity, we abolished the imperial examination system......"

Little Red Riding Hood was stunned when she heard this, "No, it's such an exaggeration?"

Zuo Ci smiled, smacked his lips, felt that the champagne tasted good, and filled himself again, "Isn't there a feeling that the space-time dimensional wall has been broken?"

Seeing Little Red Riding Hood nodding, Zuo Ci spoke eloquently, "Speaking of which, these historical events that are "beyond time and space" are really too numerous to mention.

There are really endless people and things in history about people and things that feel very far apart, but in fact they are not very different.

Qin Shi Huang and Archimedes were contemporaries, and three years after Qin Shi Huang's birth, Liu Bang, the ancestor of the Han Dynasty, was born in Zhongyangli, Palpa Feng Eup. Another overlord who competed with him for the world, Xiang Yu (, but twenty-four years younger than him.

Tang Bohu and Leonardo da Vinci, one of the three masters of the Renaissance, were contemporaries, the two of them, one had an excellent memory when he was young, and his reading speed could "finish one volume every night", and his paintings had high attainments in various subjects such as figures, landscapes, flowers and birds;

A man who has made great achievements in painting, architecture, music, mathematics, engineering, literature, anatomy, geology, astronomy, botany, paleontology, and many other fields, and is recognized as one of the greatest painters the world has ever seen.

The two shine in different countries, like the twin walls of Eastern and Western art in the same period.

In addition, when Oxford University was founded, the Ming Kingdom was in the Northern Song Dynasty, Cambridge University Press began to print books when Nurhachi invaded Dong Ebu, and when Harvard University was founded, the Central Plains was in the late Ming Dynasty, and in the same year, Huang Taiji changed the name of the country "Houjin" to "Great Qing".

In 1928, when a cartoon of Mickey Mouse, created by Walt Disney and his collaborator Woody Ewaux, appeared on American televisions, the land of China was a land of civil strife and warlordism.

In the fifth year of the reign of Ming Hong, under the governance of Zhu Youzhang, the Ming Dynasty appeared a short and brilliant "ruling the world" situation, and in the same year, Columbus discovered the American continent, which changed the course of world history.

In the first year of Jiajing in the Ming Dynasty, superstitious magic, Zhu Houxi, who was obsessed with cultivation, succeeded to the throne of Ming Shizong, and also created a situation of "Jiajing Zhongxing" in the early part of his reign, but in the later period, because of his belief in Taoism and favor traitorous ministers, it led to corruption in the government, and in the same year, Magellan's fleet completed the circumnavigation of the world and opened up a new route, which also proved the theory of the circle of the earth. As a result, the ties between the countries of the world have been strengthened, and the era of the "global village" is about to arrive.

In the fourth year of the Kangxi reign of the Qing Dynasty, British scientist Robert Hooke discovered plant cells when he used a microscope made by himself to observe plant tissues. Nine years later, Leeuwenhoek, a Dutch microscopist and pioneer of microbiology, invented the world's first optical microscope and used this microscope to observe red blood cells for the first time, ushering in an era of human beings using instruments to study the microscopic world.

In the 26th year of the Kangxi reign of the Qing Dynasty, Newton, who was 11 years older than Kangxi, published "The Mathematical Principles of Natural Philosophy", in which he systematically expounded the three laws of motion and the law of universal gravitation, summarized the basic laws of mechanical motion, and established a complete system of classical mechanics. ”

Little Red Riding Hood was dumbfounded when she heard this, and her title changed unconsciously, "My dear, I didn't expect you to be so knowledgeable, I have learned all these things, but I never thought that the contrast would be so strong when put together, and when we look at it this way, we are still lagging behind after all." ”

As an ancient man who traveled to modern times more than 1,700 years ago, Zuo Ci was naturally very interested in the history of the future compared to himself, so he studied it in depth and listened to Little Red Riding Hood's sycophants, but he did not have a smug expression.

In fact, the difference between the "old and the new" in this part is not as strong as the aforementioned events that feel long apart but do occur at the same time. The reason for the difference here is that the Celestial Empire and Europa have different definitions of modern and modern historical chronology.

In 1957, mankind discovered the "last piece of land" on Earth's "Berkna Island" in Antarctica, and in the same year, mankind launched the first artificial earth satellite, Sputnik 1.

Two events marked the end of geographical discoveries and the beginning of the space age.

The wheel of history never stops, and only time knows whether human beings are omnipotent or will eventually achieve nothing.

But you don't have to be presumptuous, when the Celestial Empire was civilized and began to eat with chopsticks, the Europa people still used their hands to grasp it, and they still use knives and forks to this day. There are many examples of such a comparison between the strong and the weak in the west, and there are a lot of them in the "History of Chinese Science and Technology" in science and technology, not to mention the humanities, the key is to see which aspect you want to look at. ”

Little Red Riding Hood nodded, and found that Zuo Ci had drunk the champagne in the wine glass again at some point, and poured himself another glass, a bottle of champagne had bottomed out, and he had already leaned against Zuo Ci in the small talk just now, and the third leg was as hard as steel, Little Red Riding Hood couldn't hold it back, and said unabashedly, "Honey, do you want to go to the bathroom?"

Zuo Ci was drunk, and the stamina of the depth charge began to attack, staggering, "Okay, I'm a little dizzy, you can help me go." ”
