Who invented soup?

If it is.

In the Neolithic Age of China (6000- 2000 years ago), people have been able to master the techniques of using fire and making different pottery. At that time, there were bowls, plates, cups, bowls, pots, beans and other tools, and the food culture was greatly improved. The appearance of pottery provides conditions for the emergence of boiling methods such as steaming and boiling. At first, most ancestors heated food with water. So, soup should be discovered at that time.

There are many theories about who invented the origin of the Lantern Festival. It is said that there was a maid-in-waiting named Yuanxiao in Emperor Wu of the Han Dynasty, and jiaozi did a good job. Yuanxiao missed her parents and sisters at home and moved Dong Fangshuo. Dong Fangshuo invented a story, saying that the Jade Emperor wanted to burn Chang 'an and requested the approval of Emperor Wu of Han Dynasty. On the 15th day of the first month, every household made glutinous rice balls and lit lanterns, and at the same time allowed the queen and ladies-in-waiting to go out of the palace to enjoy with the people and ward off evil spirits. On that day, Yuanxiao wrote the word "Yuanxiao" on the lantern, took jiaozi with his own bag out of the palace, and successfully reunited with his parents and sisters. Since then, jiaozi has also been called Yuanxiao. On the other hand, after Li Shimin proclaimed himself emperor, he was constantly harassed by foreign enemies, so he sent general Guo Ziyi to war. When I won the battle and returned to Li, it was already the Spring Festival. Li Shimin decided to give Guo Ziyi a new year on the 15th and 16th of the first month and treat Guo Ziyi with a fresh meal. The royal chefs in the palace are all bitter, and finally came up with a kind of food that grinds rice into flour and then fills it in; Li Shimin, Guo Ziyi, Wei Zheng and other ministers agreed to eat this food and asked what it was called. The cook had a brainwave and said it was called "white dough". Wei Zhi said: "These white doughs are round, symbolizing the unity of the world and the reunion of people. Let's call them dumplings! " Li Shimin was overjoyed and told everyone to eat glutinous rice balls on this day. The common people said that after the sound, it became glutinous rice balls; The fifteenth day of the first month was originally the Shangyuan Festival of Taoism, and later it was renamed the Lantern Festival. According to netizen Bei Qiang, it is said that Zhao, the king of Chu, sailed across the Yangtze River on the 15th of the first month and saw some sweets floating on the river. After asking Confucius, Confucius said, "This duckweed fruit is also a sign of the resurrection of the Lord." In fact, the above statement just shows that the origin of Yuanxiao has long been forgotten. I can't remember which year it was. The author read Su Shi's "Huanxisha", "Who cooks cocoons and smells like a village?" It suddenly occurred to me at that time that the image and taste of boiled cocoon were too similar to those of boiled Yuanxiao. In fact, China people first invented the technology of sericulture, spinning and weaving silk fabrics, which can be traced back to 7000 years ago and left many legends. For example, the story of Lei Zu, Princess of the Yellow Emperor, raising silkworms, the story of Matou Niang's silkworms and horses, and the Classic of Mountains and Seas also recorded the content of "spinning field". In the early days, before sericulture began every year, Queen Gong Zheng (the first lady of the country) presided over the ceremony of offering sacrifices to the silkworm god (the emperor presided over the ceremony of plowing the fields, which was in line with the practice of men plowing and women weaving). Generally speaking, offering sacrifices to the gods is like the presence of the gods, that is, the activities of offering sacrifices to the gods should simulate and reproduce the relevant scenes. Therefore, the author speculates that one of the scenes of offering sacrifices to the silkworm god is to simulate the image of boiling silkworm cocoons in order to wish the sericulture a bumper harvest that year. So, what is the symbol of cocoon? It is estimated that many kinds of food have been used, but the last one handed down is Yuanxiao or Tangyuan (probably because it is particularly resistant to cooking). Snow-white rice flour symbolizes cocoon silk in the outer ring, and the reddish-brown stuffing inside represents silkworm chrysalis, which should be said to be lifelike. Interestingly, the divination in the Book of Changes is interpreted by the author as "the behavior and precautions of sericulture" in the book "The Magical Gossip Culture and Games" (published by China Foreign Translation and Publishing Company) (the Book of Changes is actually a manual of behavioral knowledge norms). Among them, the "bed" at the beginning refers to the silkworm bed for raising silkworms, that is, "peeling" means peeling cocoons and spinning; In the sixth five-year plan, it is said that women are the leading role in sericulture. In recent nine years, "not eating fruit" refers to eating silkworm chrysalis (of course, it may also refer to eating the substitute of silkworm chrysalis-Yuanxiao). A nation with a long history, every kind of ancient food or decoration may be the product of "cultural integration", believe it or not? Note1:At noon on the Lantern Festival, 20065438+0, I posted a sentence in the reading forum, "According to my research, Yuanxiao originated from the ancient people cooking cocoons" to celebrate the Lantern Festival. In the afternoon, I am going to continue to create a fairy tale of Shan Hai Jing. Unexpectedly, I glanced at BBS, an overseas netizen and Mr. Symbol, and asked to write relevant research quickly. I had to come to an urgent chapter to let netizens enjoy the Lantern Festival. Note 2: On the Lantern Festival in 2002, the above words were re-posted on BBS, and some netizens raised some questions about this view. First, I think it's a little early to sacrifice to the silkworm god on the fifteenth day of the first month. In such a cold day, there are neither mulberry leaves nor silkworm babies. In fact, the first day of the first month is regarded as the Spring Festival, which indicates that the arrival of spring in that era was earlier than today. Moreover, it is understandable that the time for offering sacrifices to the silkworm god is a little ahead of schedule. In fact, it is somewhat similar to the mobilization order for sericulture production, and of course it should be released in advance. Another point of view is to analyze the problem from the etymological point of view, and think that Yuanxiao refers to Yuanxiao, that is, the night of the full moon in the first month of each year, just as people call the first day when the sun rises every year New Year's Day, so it has nothing to do with offering sacrifices to the silkworm god. The mistake of this view lies in completely separating the name of time from the name of food, and replacing the cultural connotation of food with the cultural connotation of time. In fact, the ancients cooked silkworm cocoons with the symbol of cooking Yuanxiao, in order to achieve the function of offering sacrifices to the silkworm god, which did not prevent this day from being Yuanye (it is estimated that the time for offering sacrifices to the silkworm god was not fixed at first, and then Yuanye was chosen because it was a time that everyone could easily master). In my opinion, in ancient times, people rarely went out to work, so the spherical shape of Yuanxiao didn't mean reunion at first; As for symbolizing the full moon with Yuanxiao and cooking it, it is a nondescript view imposed on the ancients. In fact, if the food Yuanxiao really has any cultural connotation, I'm afraid there is nothing more suitable than symbolizing the sacrifice of cooking Yuanxiao to the silkworm god. As for the position of the silkworm god in people's minds at that time, it can be proved by the invention or improvement of sericulture technology by Princess Zheng of the Yellow Emperor, and it can also be proved by the stripping divination of sericulture knowledge in the ancient behavior manual Yijing. One way to interpret the Book of Changes is to explain the structure, shape and relationship of hexagrams, one way is to explain the divination function of hexagrams, and the other way is to explain the social and cultural connotation of hexagrams. I have adopted a third perspective in the interpretation of the Book of Changes, that is, I think the Book of Changes is a code of conduct manual in the early Zhou Dynasty. The key to stripping hexagrams is how to explain the "bed" and why the ancients stripped the bed. My explanation is that the "bed" here refers to the silkworm bed, that is, the place where silkworms put their cocoons on the shelf and peel them from the silkworm bed. Because silkworms are prone to illness, there are many taboos in raising silkworms. Stripping hexagrams is about the taboo and possible consequences of sericulture.

Who invented Meng Po Tang? Don't think about it until then. The world is full of miracles. Maybe it does exist. I don't think it tastes, even if it does, you should forget it the moment you drink it. Since you asked this question, I suppose you believe these things exist? Are you reincarnated now? Do you remember its taste? The answer is no, so live every day well, don't miss all the ups and downs, and don't waste your life. I hope you can understand!

+,-,×, Who invented it? The invention and use of mathematical symbols are later than numbers, but they are much more numerous. Now there are more than 200 kinds in common use, and there are more than 20 kinds in junior high school math books. They all had an interesting experience.

For example, there used to be several kinds of plus signs, but now the "+"sign is widely used.

+comes from the Latin "et" (meaning "and"). /kloc-in the 6th century, the Italian scientist Nicolo Tartaglia used the first letter of "più" (meaning "add") to mean add, and the grass was "μ", which finally became "+".

The number "-"evolved from the Latin word "minus" (meaning "minus"), abbreviated as m, and then omitted the letter, it became "-".

It is also said that wine merchants use "-"to indicate how much a barrel of wine costs. After the new wine is poured into the vat, a vertical line is added to the "-",which means that the original line is erased, thus becoming a "+"sign.

/kloc-In the 5th century, German mathematician Wei Demei officially determined that "+"was used as a plus sign and "-"was used as a minus sign.

Multipliers have been used for more than a dozen times, and now they are commonly used in two ways. One is "x", which was first proposed by British mathematician orcutt on 163 1; One is "",which was first created by British mathematician heriott. Leibniz, a German mathematician, thinks that "×" is like the Latin letter "X", so he opposes it and agrees to use "×". He himself proposed to use "п" to represent multiplication. But this symbol is now applied to set theory.

/kloc-In the 8th century, American mathematician Audley decided to use "×" as the multiplication symbol. He thinks "×" is an oblique writing of "+",which is another symbol of increase.

""was originally used as a minus sign and has been popular in continental Europe for a long time. Until 163 1 year, the British mathematician Orkut used ":"to represent division or ratio, while others used "-"(except lines) to represent division. Later, in his book Algebra, the Swiss mathematician Laha officially used "∫" as a division symbol according to the creation of the masses.

The square root number was once represented by the combination of the first and last letters of the Latin "root". /kloc-At the beginning of the 0/7th century, the French mathematician Descartes used "√" for the first time in his Geometry. "R" is a variant of the Latin word line "R", and "-"is a closed line.

/kloc-in the 6th century, the French mathematician Viette used "=" to indicate the difference between two quantities. However, Calder, a professor of mathematics and rhetoric at Oxford University in the United Kingdom, thinks that it is most appropriate to use two parallel and equal straight lines to indicate that two numbers are equal, so the symbol "=" has been used since 1540.

159 1 year, the French mathematician Veda used this symbol extensively in Spirit, and it was gradually accepted by people. /kloc-In the 7th century, Leibniz in Germany widely used the symbol "=", and he also used "∽" to indicate similarity and ""to indicate congruence in geometry.

Greater than sign ">" and less than sign "

Who invented perfume and how? The word perfume comes from the Latin word "per fumum", which means "penetrating smoke". The perfume mentioned in the Old Testament usually refers to the formation of a spice, which is consistent with the Latin definition. Egyptian history shows that essence and ointment are used in bathing and after bathing. They are usually kept in exquisite containers, which are found in the tombs of ancient Egypt. In the Middle East and other parts of the Far East, as well as China, people have long learned to use the fragrance of spices to realize the pursuit of beauty. In BC 1500, the use of perfume became more and more common. Cleopatra often bathes with 15 kinds of perfume and sesame oil, and even soaks the sails with perfume. The ancient Romans liked to spray perfume everywhere, on horses and even in the mortar for building walls. In ancient Egypt, it was illegal not to wear perfume in public places. After the death of the ancient Egyptians, the corpse was wrapped with spices to make it last forever (mummified). Ancient Greek women also put perfume on religious ceremonies. Some people think that Persians discovered how to extract the essence from flowers by distillation; The Arabs created religious ceremonies using perfume. It is their use of exotic spices that laid their important position in the perfume development industry in the next few centuries. Asians have a great influence on the development of perfume use. They think that perfume can not only make people more beautiful, but also make people live longer. Later, with the decline of the Roman Empire, the development of perfume was divided into two different fields. On the one hand, German priests invented distillation technology; On the other hand, the perfume kingdom-a unique perfume introduced by France from the East, explores its aromatic characteristics. As a result, European perfume technology began to enter a prosperous period. /kloc-the first batch of modern perfumes was born in the 0/4th century. It is a mixture of essence and alcohol, and was developed at the request of Queen Elizabeth of Hungary. From15th century to the end of19th century, Italians widely used perfume. /kloc-In the 6th century, there was a strong smell of animal fat, which soon spread to France, Britain and other European countries. 1709, Italian Johann Maria Farina made a magical liquid with a strange smell in Cologne, Germany, which was called Cologne water. When Catherine de medici married Henry II of France, she came to France with her perfumer and opened her first perfume shop. French people who love clothes and cosmetics show unusual enthusiasm for perfume and are eager for it. Louis XIV was addicted to perfume and became "the emperor who loved perfume". He even called on his subjects to wear different perfumes every day. In the period of Louis XV, Madame Pompadou and Madame du Barry had a special liking for perfume just like clothing, and they did the same thing from top to bottom in the palace. Therefore, everyone's ornaments and clothing, and even the whole court, were full of fragrance, and they were called "the palace of perfume", and the whole Paris became the "perfume capital". Marie Antoinette, the queen of Louis XVI, especially likes a perfume with viola and roses as the main raw materials. At this time, the trend of perfume bathing was once again set off, and the luxury that had never been seen since Roman times was restored. At that time, perfume was considered to have the functions of relieving fatigue, relaxing nerves and treating diseases. At that time, people sprinkled perfume on handkerchiefs and carried it with them to make the whole body smell. Later, because Marie Antoinette was hanged during the French Revolution, she was named "The Essence of Hanging". Another perfume fan is Napoleon. During the election campaign, he used 65,438+02 kilograms of perfume ("fagonard") every day. When he was exiled to the island, he made mint perfume, called eau de toilette, which became a model of perfume in the future. Queen Josephine has a special liking for musk, so that she left the good name of "Musk Queen". With the development of perfume industry, flower planting has become an important industry in the south of France18th century and continues to this day. With the development of perfume industry and the increasing particularity of perfume, the demand for basic perfume increases. Therefore, flowers, fruits, trees and anti-volatile agents used to make perfumes are produced all over the world. /kloc-Since the second half of the 9th century, volatile solvents have replaced the early distillation method, especially the birth of French synthetic perfume. Perfume is no longer limited to a single natural fragrance, and the perfume family has also grown rapidly, laying the foundation for modern perfume industry. At the beginning of the 20th century, Europe was permeated with an atmosphere of freedom and independence. After the First World War, people were liberated from the Victorian era, and perfume just reflected the brand-new atmosphere of freedom at that time. At that time, because of the war, the female population was nearly 2 million more than the male population. /kloc-women in the 1920s were romantic models, and they chose the floral fragrance with feminine charm from a limited choice to show their charm. With the evolution of the times, women have broadened their horizons towards society, so the fragrance of perfume is a little less rich and sweet, mixed with dry and moist quaint fragrance. In the 1920s, women's clothing, perfume and image all changed from classical to modern. All this is attributed to the French fashion master Chanel, who created the world's first perfume containing acetaldehyde-chanel no.5. This classic perfume has a refreshing and elegant fragrance, which embodies the self-reliance and rational spirit of women in the new era and makes women wearing professional clothes solemn and charming. Another perfume, ar Peng, contains acetaldehyde and brings together more than 60 kinds of flowers, fruits and woody plants. Its fragrance is elegant, fresh and refined, which makes people fondle it. With the expansion of women's social activities, women began to use different perfumes on different occasions. Guerlain, a famous French cosmetics company, launched the first oriental perfume, showing its unrestrained * * * and mature charm. Since then, perfumes with oriental spices and exotic scents of oriental plants have been deeply loved by women.

Please accept it, thank you!

+Who invented it? 1. When did the symbol of addition, subtraction, multiplication and division begin to exist? Which symbol in "addition, subtraction, multiplication and division" was first invented? For a long time after the birth of numbers, people only knew how to count, but could not write the process of calculus. Until more than 500 years ago, German mathematician Wei Demei realized in the practice of calculus that addition and subtraction operations must have literal symbols and be simple and clear. So according to the writing law of the capital letter T, he first wrote it horizontally, and then added a vertical line in the horizontal direction to indicate the increase, which became the current "+". Before long, he invented the minus sign. According to the definition of subtraction, he thinks that removing a vertical line from the "+"sign means less than the original. About 300 years ago, the British mathematician Audley thought multiplication was a special form of addition, so he rotated the "+"invented by his predecessors by 45 degrees, and "×" came out. 2. When was the division symbol in addition, subtraction, multiplication and division invented? It was more than 300 years ago that Swiss mathematician Hana invented "Xi Xi". He thought division was to decompose a number, so he cut a whole thing with a horizontal line to indicate demarcation. About 400 years ago, British scholar Colder invented the number "=". According to the habit that people liked to regard the things that were balanced as equal at that time, he thought that the most vivid way to write balance was to use two parallel lines with the same length, so the equal sign "=" was born.

Who invented the school? Who invented the exam again! Look at ancient history and you will have the answer. If you really want to find out.

But I think you seem to be in a bad mood. Calm down and do what you have to do.

Who invented the abacus? When was it invented? Abacus, also known as abacus, is a simple calculation tool invented and created by Han working people. It was invented by Xu Yue more than 2600 years ago.

China is the hometown of abacus. Today, computers have been widely used. The ancient abacus has not been abandoned, but it is in the ascendant in many countries because of its convenience and accuracy. Therefore, people often compare the invention of abacus with four great inventions of ancient china. There is an abacus in Zhao Taicheng's medicine cabinet in the famous painting "The Riverside Scene at Qingming Festival" in the Northern Song Dynasty. Because of its convenient operation, abacus has been widely used by working people of Han nationality for thousands of years, and even the most advanced modern electronic calculator can not completely replace the role of abacus. UNESCO has just passed in Baku, the capital of Azerbaijan, and abacus has officially become the intangible cultural heritage of mankind. This is also the 30th non-legacy project in China.

The abacus is a traditional calculation tool in China. It was invented by China people on the basis of long-term use of calculation. It was a great and important invention in ancient China. Before Arabic numerals appeared, it was a widely used calculation tool all over the world.

The origin of abacus can be traced back to the late Han Dynasty and three generations, which was invented by Guan Yu. It is said that there was a "computing board" in China at that time. The ancients strung 10 abacus beads into a group, arranged them in groups, put them in boxes, and then quickly set aside the abacus beads for calculation.

According to public information, the word "abacus calculation" was first seen in Shu Shu Ji Yi written by Xu Yue in the Eastern Han Dynasty.

Among them, there is a cloud: "The abacus controls the four seasons, and the latitude and longitude are three talents." Zhen Luan of the Northern Zhou Dynasty made an annotation to this effect, to the effect that the board was carved into three parts, the upper and lower parts were used to block the beads and the middle part was used to locate them. Everyone has five.

Beads, the upper beads and the lower four beads are distinguished by color, which is what is later called "file". There are five beads on the top and one on the bottom. Today's explanation is that the abacus is rectangular, with thin sticks embedded in the wooden frame and numbers on the sticks.

Disc beads and abacus beads can move up and down along thin rods, and arithmetic operations can be completed by moving abacus beads by hand. [2]

In ancient times, people used small sticks to calculate. These sticks are called "computing chips", and calculations with computing chips as tools are called "calculations". Later, with the development of production, the calculation with wooden sticks was limited, so people invented a more advanced calculation tool-abacus.

In the Ming Dynasty, abacus can not only add, subtract, multiply and divide, but also calculate the area of land and the size of things of various shapes.
