From the late 19th century to the early 20th century, what were the developments of science and tech

1. The development of new energy and the use of energy - everything that can provide energy can be called energy. Let us recall that during the first period of the industrial leather wheel preparation for the early life, due to the hydraulic engine machine was subjected to natural bars.

An important feature of the development of science and technology in the 19th century is (d).

a.Integration of science and technology.

b.Science and technology synchronized.

c.It's technology that gets ahead of science.

d.It is science that goes ahead of technology

In the late 19th century, the development of science and technology was manifested in three aspects: the development and application of new energy; the creation of new machines and vehicles; Invention and application of new messaging technologies and devices. Features: Electricity as the core, extensive.

China's science and technology history has a long history, China's science and technology, in a long historical period have been in the leading position in the world, the vast scientific and technological achievements, for the development of world civilization has made outstanding contributions.

The greatest achievements are in agriculture, astronomy, mathematics and traditional Chinese medicine, and many scientific and technological achievements such as the "Four Great Inventions" have been born that have influenced the course of world civilization.

The embryonic period of Chinese science and technology includes the Paleolithic and Neolithic periods. China is one of the birthplaces of the world's early human civilization, and is one of the first regions in the world to use fire, invent bows and arrows and pottery, appear agriculture and animal husbandry, observe astronomical spikes, and pioneer medicine. And at this time, silk also began to be used.

China's science and technology development strategy is divided into two parts: one is directly oriented to the current economic development, and the other is to serve the development of the national economy at the end of the 20 th century and the beginning of the 21 st century.

The main content of China's science and technology development strategy during the Seventh Five-Year Plan period is to transform traditional industries with emerging technologies and form a systematic and supporting scientific and technological capability for transforming traditional industries.

We should do what we can, selectively develop high technology, and serve the formation of new industries. Vigorously develop and popularize applicable supporting technologies to serve the revitalization of the local economy. Strengthen support for applied research and basic research that have a far-reaching impact on the development of the national economy.

The science and technology of the 20th century also created television, nylon, and plastics, which greatly changed people's lives.

1. TV. The birth of television is one of the greatest inventions of mankind in the 20th century. In modern society, life without television is no longer conceivable.

Black-and-white and color TVs of all models and functions are miraculously and rapidly changing people's lives from assembly lines to factories, schools, hospitals, and homes around the world.

2. Nylon. Carothers, an American organic chemist, made a polymer from adipic acid and hexamethylenediamine in 1935, which was called polymer 66 at that time because these two components contained 6 carbon atoms. He melted the polymer and pressed it out with an injection needle, where it was stretched under tension called a fiber.

This fiber, polyamide 66 fiber, was named nylon after industrialization in 1939, and it was the earliest synthetic fiber variety to achieve industrialization.

3. Plastics. In the 60s of the 19th century, due to the shortage of ivory in the United States and the lack of raw materials for making billiards, the earliest artificially manufactured plastic celluloid was patented in 1869. Although celluloid is the earliest artificially manufactured plastic, it is a man-made plastic, not a synthetic plastic, the first synthetic plastic is a phenolic resin heating mold, which was made in the early 20th century, in 1910 by the American-Belgian chemist Beckland.

The significance of the invention of plastics

Plastic products are too common around us, you need plastic bags when you go to the supermarket to buy things, the packaging bags of snacks are also plastic, the crisper boxes you use to put food are also plastic products, and the silicone you use for smartphones, household appliances, cars, and even breast augmentation all contain plastic materials.

Plastic alone has saved the lives of countless elephants, so many environmentalists have no reason to hate plastic products, not because plastic pollutes the environment, but humans pollute the environment.

Plastic has also left valuable audio-visual materials for our human history, in the past, it was difficult for us human beings to leave any ** information except painting, and those who could afford to hire painters were rich, and the poor naturally could not leave anything.

In the 20th century, the main achievements in the field of science included the theory of relativity, quantum mechanics, quark elementary particles, the double helix structure of deoxyribonucleic acid, the theory of the expansion of the universe, and the emerging complex science. The technical fields include various means of transportation, aerospace technology, mass production technology, chemical synthesis technology, atomic energy technology, semiconductor technology, laser technology, wireless communication technology, electronic computers, digital technology, etc.; In the field of life science and biotechnology, there are pathogen discovery, drugs to resist pathogens, organ transplantation, genetically modified technology and cloning technology of animals and plants, as well as medical instruments such as computerized chromatography devices, nuclear magnetic resonance machines, and ultrasound diagnostic instruments.

Summary. Hello, here for you to find out, the rapid development of science and technology in the 20th century is based on the major scientific theoretical achievements of the 19th century, such as the theory of thermodynamics and electromagnetism, the theory of chemical atomism, the theory of biological evolution and the theory of cells.

Hello, here for you to find out, the rapid development of science and technology in the 20th century is based on the major scientific theoretical achievements of the 19th century, the theory of thermodynamics and electromagnetism, the theory of chemical atomism, the theory of biological evolution and the theory of fine vertical cells.

Is it okay to ask questions quickly? I ask you, how far did science and technology come in the 20th century?
