When working with a set of instruments outside the space station, assume that the astronaut accidentally disconnected from the station and found himself at a short distance from it. How can he get close to the station?
The astronaut pulls out a pistol-like device, aims at the opposite side of the rocket and releases the hook. Compressed air escapes from the barrel of the “pistol” and the reactive force returns the astronaut to the station.
Remember: The process of learning a person lasts a lifetime. The value of the same knowledge for different people may be different, it is determined by their individual characteristics and needs. Therefore, knowledge is always needed at any age and position.
