Mechanics and Technology

Where was an artwork (in the same way every product) before it was created? In the beginning there was a movement of Wisdom (mind), after that there was the artwork. What’s going to happen to the artwork through its entire existence? What happens to the artwork...

Physics of energy conversion

From definition of base units follows – the time is equal to the frequency of oscillation of electromagnetic waves, these oscillations need a space, the volume. Matter is a special form of “frozen or bounded” oscillations. There is no so big...

Measurement and Regulation

Where is the right value N? We are unable to measure directly right value N of something – diameters of balls or anything else. We are only able to measure a certain amount of values that, in effect, when plotted, resemble Gauss’s distribution curve of...
