Modern space flight would not be possible without computers. Just think of the launch of a moon rocket. Long before they are launched, tens of thousands of important pieces of data are stored in the memory of a huge computing facility: precise information about the planned speed and direction of the rocket and the space capsule, about the necessary flight characteristics, about all the preconditions for the functioning of the electronic devices and the supply system, about breath, Heartbeat, astronaut body temperature and much more. It's time to start, the computer system is "fed" with all the information about the current state of the rocket system and the astronauts. The computer compares them with the stored data within a few seconds. All agree, a lightbulb lights up, which indicates: “All conditions for the start are fulfilled!’ Later the missile deviates only slightly from the course, an electronic device indicates it immediately and calculates the course correction. No human arithmetic can compete with computers in terms of speed. And quick calculations are often vital, when it comes to decisions, on which the fate of the astronauts depends. Electronic machines can do calculations and comparisons for humans – but not the scientific one, mathematical thinking.
