The four revolutions in history have promoted the rapid development of the huge wheel of social progress. How much do you know about the revolutions?
The pot lid of boiling water will lead us into the steam age

In 1785, inspired by the pot lid of the boiling water, the improved steam engine made by Watt was put into use, it has provided a more convenient driving force for production and has been rapidly promoted, which greatly promoted the popularization and development of the machine. As a result, human society has entered the "steam age".

The development of machine production has promoted the innovation of the transportation industry. In order to transport goods and raw materials quickly and conveniently, people tried their best to transform the means of transportation. In 1807, the steam-powered steamboat made by Fulton, an American, was successfully tested. In 1814, the Englishman Stephenson invented the "steam locomotive". In 1825, Stephenson personally drove a train with 34 small carriages to test the car and then succeeded. From then on, the transportation page of human beings entered an era of steam power.

This great revolution in the history of technological development has created an era of replacing manual labor with machines. This is not only a technological reform, but also a profound social change, which has promoted the development leap in the economic field, the political field, the ideological field, the world market and so on.

Electricity not only lights up the lamp bulb, but also brightens the whole world

In the last 30 years of the 19th century and the beginning of the 20th century, the advancement of science and technology and the rise of industrial production were called the second industrial revolution in modern history. The world entered from the "steam age" to the "electrical age."

During this period, the total industrial output value of some developed capitalist countries exceeded the total agricultural output value; the industrial focus shifted from light textile industry to heavy industry, with the emergence of electrical, chemical, petroleum and other emerging industrial sectors. Since the 1970s, generators and motors have been invented successively, and the emergence of long-distance transmission technology, the electrical industry has developed rapidly, and electric power has been widely used in production and life.

An epoch-making computer that makes the world a whole

Since the 1940s and 1950s, human beings have made major breakthroughs in the fields of atomic energy, electronic computers, microelectronics, aerospace technology, molecular biology and genetic engineering, marking the arrival of a new scientific and technological revolution. This technological revolution is known as the Third Technology Revolution.

It has produced a large number of new industries, and the tertiary industry has developed rapidly. Among them, the most epoch-making significance is the rapid development and widespread use of electronic computers, which opened up the information age. It also brings a new type of economy—the knowledge economy. The degree of development of knowledge economy has become the key to the success or failure of the comprehensive national strength competition of various countries.

This scientific and technological revolution has not only greatly promoted the transformation in the social, economic, political, and cultural fields of human beings, but also affected the way of life and thinking of human beings, and enabled the development of human social life and human modernization to a higher level.

Intelligence, take you into a whole new world
The fourth industrial revolution is a technological revolution based on artificial intelligence, clean energy, robotics, quantum information technology, controllable nuclear fusion, virtual reality, biotechnology, and blockchain.

The first three industrial revolutions have brought human development into an era of unprecedented prosperity. At the same time, it has also caused huge energy and resource consumption, and has paid a huge environmental cost and ecological cost, which has dramatically expanded the contradiction between human beings and nature. In the 21st century, human beings are facing an unprecedented crisis, so economic and social development needs a comprehensive transformation.

Blockchain technology, as an important part of the fourth industrial revolution, has experienced ten years of development and has been recognized by more and more countries. In the new era, the old order and old ideas of the industry will also be baptized by the revolution.
