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. 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. 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. Electronic machines work according to a programme, prepared in advance, which determines the sequence of operations. They have a very efficient electronic “memory” which stores the initial data, the intermediate numbers and final results as well as working commands given to the machine. The electronic machine can also be used for controlling automatic production. Signals given by measuring instruments and controlling devices are introduces into the machine which sends the necessary commands to the control panel according to the programme. All the instruments invented up to now have served to save mains labour. But it is electronic computers the importance of which cannot be underestimated that come to the help of the human brain, thus opening boundless possibilities.
