Engineering – interesting development of human beings called engineers. In the beginning, in prehistoric times, there was only ore, coal, limestone and fire. Throughout ancient times, engineers made metal tools, weapons and simple mechanisms (water wheels, screw pumps). In the Middle Ages, engineers built (not that they built or replicated themselves) the first mechanisms such as mechanical clocks, weaving looms and so on. And in modern times, we already have mechanical computing devices, typewriters, precise pendulum clocks, right down to high-precision atomic clocks.

All tools, devices, devices over the ages (from swords and knives to various mechanisms and processes to high-precision atomic clocks) did not happen randomly. They didn’t just happen by the way. But they were created by a big effort, a painful and joyful experience of a few people called engineers. It doesn’t matter what you are, if you’re an engineer, scientist, artist, craftsman, carrier, economist, hairdresser, pilot, doctor, teacher or something else. One should be something – to reach the fullness of humanity. Live out the painful experience with following immense joy of the obtained abilities. And so still.

The devices were built not by themselves, but by experienced and capable people. Watchmaking is a beautiful example. The accuracy of clocks increased through the ages to the current level of atomic clocks. These instruments did not self-construct, they were built by engineers. In fact, the machine with given accuracy produces another machine (even itself) with a given original accuracy – no more! A machine production with a given accuracy cannot produce, for example, more accuracy gears than the given accuracy of the machine.

At first glance, a mystery of increasing accuracy of products. How to achieve with a given accuracy of the production machines a much higher accuracy of products.
