What is an analog computer?

Analog computers refer to computers that use a continuously changing analog quantity as the object of operation based on the principle of similarity. Analog computers use electronic circuits to form the basic computing component, which is composed of computing components, control components, layout boards, input and output devices, etc. The analog computer is based on parallel computing and has fast calculation speed; and it appropriately combines arithmetic units with fixed functions, so the program is relatively simple, but the flexibility of problem solving is relatively poor.

What is an analog computer

An analog computer is a computer that uses a continuously changing analog quantity as the object of operation based on the principle of similarity.

Analog computers use electronic circuits to form the basic computing components. It consists of computing components, control components, question setting boards, input and output devices, etc. The concept of simulation is included in the solution using the principle of similarity, so it is called an analog computer. It is based on parallel computing and has fast calculation speed. It appropriately combines arithmetic units with fixed functions, so the program is relatively simple, but the flexibility of problem-solving is relatively poor.

Application:

The input and output quantities of each main component are continuously changing physical quantities such as voltage and current. . Analog computers are composed of several integrators, adders, multipliers, function generators and other components with different functions and quantities. According to the mathematical model of the problem to be studied, the output terminal of one component is interconnected with the input terminal of another or several components, so that the mathematical relationship between the output and input quantities of the entire computer simulates the objective process of the problem under study. The solution to the equation y(t) is obtained at the output end; the interconnection relationship between the simulated computer components varies with the problem. Some people call the design of this connection relationship a problem-solving program.

#According to foreign media reports, the Milky Way we see today evolved over billions of years. What began as a loose mass slowly grew into a massive, spiraling disk of stars. Faced with such a complex galaxy, astronomers have been trying to gain a deeper understanding for years. Now, thanks to the most detailed computer simulations ever produced, we can glimpse how the Milky Way formed in just seconds.

Previously, astronomers have also tried to use computer simulations to solve the problem of dwarf galaxies - known as the "missing moon" problem - but until now there has been no final answer.
