The article considers the evolution of some branches of modern economic theory from the perspective of the authors biography as a scientist and his professional formation. It describes problems of econometrics, general equilibrium theory, uncertainty, economics of information, and growth. It is shown how different authors representing various fields came to similar conclusions simultaneously and independently, what were the problems, in response to which economists of the second half of last century developed their theories, and what were the contexts of such development.

This paper discusses the experimental examination of anisotropic steel-made samples subjected to a static stress load. A nondestructive testing (NDT) measurement system with a transducer, which enables observation of local hysteresis loops and detection of samples’ inhomogeneity, is proposed. Local hysteresis loops are measured on two perpendicular axes, including one parallel to the rolling direction of the samples. The results confirm that the selected features of the local hysteresis loops provide important information about the conditions of ferromagnetic materials. Furthermore, it is shown that the selected parameters of the statistical analysis of the achieved measurements are beneficial for evaluating stress and fatigue changes induced in the material.
