How did symbols come about, and what is the origin of operational symbols?

Any kind of symbol is made up of two aspects: content and meaning.

Any kind of symbol is composed of two aspects, that is, content and meaning, it can be understood in this way, on the surface, it is indeed a visually visible image thing, but the symbol represents a certain meaning.

Symbols contain two aspects, form and meaning, and the two are inseparable. Language symbols are composed of the combination of sound and meaning, sound is the material expression of language symbols, and meaning is the content of language symbols. Language symbols themselves have many characteristics, mainly sound, accidental, hierarchical, and unique, and their uniqueness mainly includes linearity, arbitrariness, immutability, variability, and generativity.

Linguistic symbols include spoken language and written language in the form of written symbols; Non-verbal symbols include images, colors, light, human body language, and so on. Linguistic symbols are a tool for communication between people, and they are one of the most important communication media in human society. People use language symbols to express ideas, convey feelings, and communicate knowledge.

In a philosophical sense, ideas are expressed through language. Thinking is the core of language, and symbols are the shell of language.

The symbols "and" were first used by the German mathematician Wietmann in his 1489 book Simple and Quick Calculations. In 1514, it was used as an algebraic operation symbol by the Dutch mathematician Heck, and later by the French mathematician Veda.

It was not until 1630 that it was recognized by everyone.

The multiplication sign " " is a multiplication symbol that denotes multiplication. In 1631, the English mathematician Ottshind proposed the use of the symbol " " to represent multiplication. Multiplication is another way to indicate an increase, so slant the " sign.

Another multiplication symbol "? "It was the German mathematician Leibniz.

Use it first.

Division. " is a division symbol that represents division. The use of this symbol to represent division first appeared in the Swiss scholar Rennes.

A clear algebra book published in 1656. It was only a few years later that the book was translated into English, and it was gradually recognized and accepted.

History of plus and minus signs:

The French use the method of plus and minus signs.

Frenchman Xu Kai.

1484), the Italian Pacioli (1494), and most scholars of the sixteenth century used the initials of the Latin words plus (plus) and minus (minus) as plus (or p) and minus (or m), respectively.

The Italians use the method of plus minus signs.

From the end of the fifteenth century to the whole of the sixteenth century, the Italians continued to use plus and minus signs. It was not until 1608 that the German Clavius adopted the " symbol in his book Algebra in Rome, which was published in a round edition, and the Italians began to adopt these two symbols, but by the time of Cavalieri they were already proficient.

Dear, I'm glad to answer for you, how the symbol came about is as follows: The purpose of the first invention of the symbol zui is to facilitate recitation. In the past, there were many illiterates, and a small number of literate people had to read the words to others on a regular basis.

In order to facilitate recitation, the text began to have a "dot" sign. The word puntuation is derived from the Latin puntus, which means "point". These "points" let the reader know that **there needs to be a pause, ** the tone needs to be strengthened, etc.

Pro, a symbol is first and foremost a symbolic object that is used to refer to and represent other things. Secondly, the symbol is a carrier, which carries the information sent by both sides of the communication. "Signs" is one of the basic concepts of semiotics.

Symbols generally refer to words, languages, codes, mathematical symbols, chemical symbols, traffic signs, etc. But the range of symbols in semiotics is much broader, and the constituent elements of social life such as greeting actions, rituals, games, literature, art, mythology, etc., are all symbols. In short, everything that can be used as a sign of something can be called a symbol.

The origins of chemical symbols can be traced back to ancient Egypt. Ancient Egypt is one of the earliest birthplaces of chemistry, and the word "chemistry" in modern Western languages is ** from the ancient Egyptian country name "chēmia".Egypt was metallurgical long before 3400 BC (First Dynasty).

From its relics, it was found that the ancient Egyptians were very good at working with metal. The earliest exploit was gold, which existed in the form of a natural metal and was striking for its brilliant color. The second thing to know was copper, and soon bronze (copper-tin alloy) was invented

During the period of 3400 BC (pre-dynastic), the Egyptians also knew about metals such as iron, silver, and lead. The Egyptians also perfected the process of making glass, glazed pottery and other materials, and later developed techniques for extracting natural dyes. Originally, these techniques were passed down orally from father to son or between master and apprentice, leaving little written record.

With the production of writing and the need for technological development, it is necessary to record some chemical formulas and processes for reference and future generations. In order to keep the technology secret so that it does not fall into the hands of outsiders, some key substances, equipment and processes cannot be expressed in common words, but need to rely on some specific symbols that only one's own people can understand. Among them, the symbol that represents the substance is the earliest chemical symbol.

It can be seen that there are two prerequisites for the production of chemical symbols: first, the development of chemical processes has reached a certain stage of maturity, so that something is worth recording; The second is the generation of words, which makes it possible to record information, and is inspired by words to formulate some specific symbols. However, due to the age and backwardness of the recorded materials, it is difficult for the world to know what the chemical symbols used in ancient Egypt looked like.
