Computers are well-known to represe

Computers are well-known to represent a relatively new branch of science, the first of them having appeared less than 60 years ago. Although still new, these machines are already brining about a real revolution in science, technology, statistics and automatic control.

The reason for this lies in the fact that a mathematical formula can found for almost all scientific and technical problems. They can be solved without a computer but would require millions of arithmetical operations. No wonder that many problems of exceptional importance remained unsolved for long time, the volume of the calculations required being above human possibilities.
With a high speed electronic computer can carry out several thousands arithmetical operations in one second. A calculation, which would have several years of intense human work in the past, is now done in a few minutes or hours.

A number of various complicated problems have already been solved with the help of computers.
The principle of this wonderful machine lies in counting electric impulses. Numbers are represented as a sequence of such impulses, and a radio-technical scheme counts them carrying out additional, subtraction, multiplication and division, all higher mathematical calculations being reduced to these four operations.
