ABSTRACT

Typical velocities of elementary particles are close to the light velocity, angular momenta represent multiples of ~/2, while energies even if they reach the order of 10−5 J, are ranked among a category of superhigh ones. Consequently, when we are trying to imagine the elementary particles world visually, one of the troubles in our consciousness is caused by the fact that constants, whose values cannot be laid in macroworld standards, present in the microworld physics formulae. On the other hand, it is easy to appreciate their values compared with each other. So, as the natural step, we should break off the connection with macroworld. It is achieved by the transition to the system of units where the fundamental physical constants of microworld are used as the basic units. Such systems are called natural system of units (NSU). The first to suggest one of NSU kinds was M. Plank. He chose ~, c, G, and k (the

Boltzmann constant) as the basic units. Under the NSU construction the fundamental constants, taking as the basic units, are formally assumed to be equal to 1. So, the Plank NSU is defined by the relation:

~ = c = G = k = 1.
