There is a vast theoretical background for evaluation of scientific works and there are a lot of ways how to, if possible, objectively evaluate the significance and quality of individual theses, authors and researches. Various evaluation elements are more or less objective in different branches of research and it is necessary to consider suitability of their use and "justness" of the final comparison. Then it depends on each metric, how it uses these and other parameters and how many iterations it logs. Elementary ways of calculation of these indicators of quality, their properties and scientific power evaluation of an researcher are briefly explained in this article.
