Examples of modern scientific and technological achievements:

1. Computer

Computer is a modern electronic computer used for high-speed calculation, which can be used for numerical calculation, logical calculation and memory storage. It is a modern intelligent electronic device that can run according to the program and process massive data automatically and at high speed.

consists of a hardware system and a software system, and a computer without any software installed is called a bare machine. It can be divided into five categories: supercomputers, industrial control computers, network computers, personal computers and embedded computers. The more advanced computers include biological computers, photonic computers and quantum computers.

II. Nuclear Power Plant

A nuclear power plant refers to a facility that converts nuclear energy into electrical energy through appropriate devices. Nuclear power plants use nuclear reactors to replace boilers in thermal power plants, and nuclear fuel is burned in nuclear reactors in a special form to generate heat, so that nuclear energy can be converted into heat energy to heat water and generate steam. The systems and equipment of nuclear power plants are usually composed of two parts: nuclear systems and equipment, also known as nuclear islands; Conventional systems and equipment, also known as conventional islands.

III. Satellites

Satellites refer to natural celestial bodies that orbit around a planet and run periodically in a closed orbit. Artificial satellites can also be called satellites in general. Man-made satellites are devices built by human beings and launched into space by space vehicles such as rockets and space shuttles, and orbit the earth or other planets like natural satellites.

gas planets often have many satellites. Nine planets * * * have 61 satellites. Except Mercury and Venus, all other planets are surrounded by satellites. According to the number of satellites, the ranking order is Saturn 18, Uranus 17, Jupiter 16, Neptune 8, Mars 2, Pluto and Earth 1 each. The size and mass of different satellites vary greatly. There are seven satellites with a radius greater than 1111km, and the moon is one of them.

IV. Submarines

Submarines or submarines are ships that can run underwater. [1]? There are many kinds and shapes of submarines, ranging from fully automatic or small civilian diving detectors operated by one or two people for several hours to Russian typhoon-class nuclear submarines that can carry hundreds of people and snorkel continuously for 3-6 months. According to the volume, it can be divided into large (mainly military), medium or small (pocket submarines, submersibles) and underwater automatic mechanical devices.

v. artificial intelligence

artificial intelligence is a branch of computer science, which attempts to understand the essence of intelligence and produce a new intelligent machine that can respond in a way similar to human intelligence. The research in this field includes robot, language recognition, image recognition, natural language processing and expert system.

since the birth of artificial intelligence, the theory and technology are becoming more and more mature, and the application fields are constantly expanding. It can be imagined that the scientific and technological products brought by artificial intelligence in the future will be the "containers" of human wisdom. Artificial intelligence can simulate the information process of human consciousness and thinking. Artificial intelligence is not human intelligence, but it can think like people, or it may exceed human intelligence.
