Top 10 historical events that influenced the development of chemistry

The history of the development of chemistry is:The historical origin of chemistry is very ancient, and it can be said that the earliest chemical practice began when humans learned to use fire. Our ancestors drilled wood to make fire, used fire to bake food, kept warm on cold nights, drove away wild beasts, and made full use of the glow and heat phenomenon when burning.

At the time, it was just an accumulation of experience. The formation of chemical knowledge and the development of chemistry have gone through a long and tortuous road. It develops along with the progress of human society and is the inevitable result of social development.

Knowledge and Skills:1. Master the basic theories and basic knowledge of mathematics and physics.

2. Master the basic knowledge, basic principles and basic experimental skills of inorganic chemistry, analytical chemistry (including instrumental analysis), organic chemistry, physical chemistry (including structural chemistry), chemical engineering and chemical drawing.

3. Understand the general principles and knowledge of similar majors.

4. Understand the national policies and regulations on science and technology, chemistry-related industries, intellectual property rights, etc.

It can be broadly divided into three stages:

1. Ignorance stage: from alchemy to iron smelting in the Spring and Autumn Period, batik screens and wine-making processes in the Tang Dynasty all belong to this stage. People's knowledge is practiced through labor, and there is a lack of theoretical summary.

2. Modern Chemistry: Dalton and Avergadro's molecular atomism laid the foundation for modern chemistry.

3. Modern chemistry: New materials and new technologies are the characteristics of modern chemistry.

1. Embryonic period.

From ancient times to 1500 B.C., human beings learned to make pottery from clay in a blazing fire, to burn metal from ore, to make wine from grain, and to dye silk and linen and other fabrics.

2. The period of pills.

From about 1500 BC to 1650 AD, chemistry was controlled by alchemy and alchemy.

In order to obtain the elixir of immortality or the ** symbolizing wealth, alchemists and alchemists began the earliest chemical experiments, and then books recording and summarizing alchemy also appeared one after another.

Although the alchemists and alchemists all ended in failure, in the process of refining the elixir of life, they realized the mutual transformation of substances by artificial methods in exploring the method of "turning stones into gold", accumulated many conditions and phenomena for chemical changes in substances, and accumulated rich practical experience for the development of chemistry.

3. Phlogiston period.

This period, from 1650 to 1775, was the gestation of modern chemistry.

With the accumulation of metallurgical industry and laboratory experience, people summarize perceptual knowledge and carry out theoretical research on chemical changes, making chemistry a branch of natural science.

The beginning of this phase was marked by the British chemist Boyle pointing out the scientific concepts of chemical elements.

Subsequently, chemistry was liberated from alchemy by phlogiston.

Although the phlogiston theory holds that combustibles can be burned because it contains phlogiston, and the combustion process is the process by which phlogiston is released from combustibles, although this theory is wrong, it unifies a large number of chemical facts under one concept and explains many chemical phenomena.

4. Development period.

This period, from 1775 to 1900, was the period of the development of modern chemistry.

Around 1775, Lavoisier expounded the oxidation theory of combustion with quantitative chemical experiments, which ushered in the period of quantitative chemistry and brought chemistry on the right track.

At the beginning of the 19th century, the British chemist Dalton put forward the modern atomic theory, which prominently emphasized that the mass of the atoms of various elements is its most basic feature, and the introduction of the concept of quantity is a major difference from the ancient atomic theory.

5. The modern period.

Chemistry in the twentieth century is a science based on experiments, and experiments and theories have always been two aspects of chemical research that depend on each other and promote each other.

Since entering the 20th century, due to the influence of the development of other disciplines in natural science, the theories, techniques and methods of contemporary science have been widely applied.

Chemistry has made great progress in understanding the composition, structure, synthesis and testing of substances, and has made many important achievements in theory.

On the basis of the four sub-disciplines of inorganic chemistry, analytical chemistry, organic chemistry and physical chemistry, a new sub-discipline of chemistry has emerged.
