What changes have taken place in the previous technology and modern technology?

Science and technology are the primary productive forces, and the development and change of society cannot be separated from scientific and technological innovation. China's science and technology has gone through a long process and detours from behind closed doors to gradually connecting with the world's development direction, from concept change to attaching importance to culture, science and technology education, from micro-investment, fixed investment and learning to macro-orientation, development and innovation.

At present, some technologies in China have reached or surpassed the world level, and many of them are high-tech independently developed and have intellectual property rights. Today, with the rapid development of global science and technology, people's morality and quality should also progress together. In this respect, we still need improvement, not retrogression.

Expand the achievements of the information technology revolution

I. Revolution

Cotton textile: the invention of a series of textile machines

Power: Watt improved steam engine (1785)

Transportation: Fulton-Steamboat (USA,1807); Stephenson steam locomotive (UK, 18 14)

1. It first happened in Britain, with Britain as the main body;

2. Taking light industry as the leading factor;

3. Taking steam power as the main symbol;

4. Technological inventions mainly come from the practical experience of workers and technicians.

Second, the second revolution

Wide application of electric power (Siemens generators, Gram motors)

Invention of internal combustion engine and new means of transportation (Karl Benz-car driven by internal combustion engine, Wright brothers-plane)

The invention of new means of communication (Bell telephone, Marconi wireless telegraph)

1. Science and technology began to be closely integrated.

The invention of new technology happened in several countries almost at the same time.

In some countries, two industrial revolutions crossed.

Three or three revolutions

The wide application of computers

Science and technology promote the development of productive forces and accelerate the transformation to direct productive forces.

2. Science and technology are closely integrated and promote each other.

3. Various fields of science and technology permeate each other.

Four or four revolutions

The wide application of the internet

The systematic science and engineering research of cells and molecules has formed an all-round bio-industrial revolution of bio-energy, bio-information and bio-materials, which will bring technological breakthroughs and industrialization of bio-solar energy, bio-computers and bioreactors.

Five or five revolutions

The wide application of robots
