The article entitled “The strange world of quanta” tries to explain, in a very general and selective way, the physics theory known as the quantum mechanics. In opposition to the classical modern theories – the classical mechanics and the mechanism – the quantum mechanics has been characterized as the new revolutionary theory which changed the scientific method and the way the reality was perceived in the XXth century. The title of this article is inspired by the apparent divergence between the everyday world and the world described by the quantum mechanics. The quantum physics is a theory which has been confirmed empirically multiple times and which greatly influenced the technological development in the XXth century. It is also hoped that it will help the humanity in the future. However, as the theory which describes the micro-scale world it stands in opposition to another influential theory of the XXth century – the general theory of relativity – which describes the macro-scale world. The problem is that these two theories can not be both fundamental and true at the same time, as they describe the two aspects of the same world. This incoherence of the laws of the universe is especially disturbing when we take into account the fact that according to the Big Bang theory the universe emerged from the micro-world. Therefore, the science community awaits the emergence of the so-called “theory of everything” which could unify both theories and explain the processes taking place in the micro- and macro-scale equally well.

This paper comprises an experimental data determining turbulence time and space macro- and microscales of liquid, in agitated vessel equipped with PBT impeller. The values have been determined on the ground of velocity autocorrelation function obtained from liquid velocity measurements in agitated model vessel, with help of LDA (Laser Doppler Anemometer) measurement system.

W pracy przedstawiono wyniki badań doświadczalnych, których celem było określenie czasowych i przestrzennych makroskal i mikroskal turbulencji cieczy w mieszalniku z mieszadłem turbinowym o łopatkach pochylonych. Wielkości te wyznaczono, opierając się na funkcji autokorelacji prędkości pobocznych, uzyskanej na podstawie wyników pomiarów prędkości przepływu cieczy w mieszalniku. Pomiarów chwilowych prędkości przepływu mieszanej cieczy dokonano za pomocą dwukanałowego anemometru laserowego.

In the paper the results of investigations determining the time and length macro- and microscales of turbulence of the liquid in a mixing vessel with the pitched blades turbine are presented. These quantities were determined on the basis of the velocity autocorrelation function obtained from the measurements of liquid velocities using the LDA method.

In the future, the crucial element of organizations, will be good organized teamwork. A succes will belong to such business units, which have a big intellectual capital used everywhere effectively. Good ideas are, in such situations, initial points for further progress The necessity of integration into better and more compact organizational structures is obvious. It is possible to distinguish the micro-, then macro-, and finally the global scale of this performance. The demonstration of problems and challenges are here discussed.
