let's look back at the history of the discovery of NMR. 1946, Harvard scientists (Purcell, Pound and Torrey) along with Stanford scientists (Bloch, Hansen and Packard) discovered the ability of proton and phosphorus-31 (1H and 31P) nuclei to absorb radiofrequency energy when they were affected by a magnetic field with the strength typical of all atoms. At the moment of absorption, the nuclei began to intensify, with both chemical elements having their own frequency. In view of this observation, it became possible to conduct a detailed study of the structure of the molecule. Since then, NMR has been introduced for kinetic and structural analyses of bodies in the three aggregate states, resulting in six Nobel Prizes.

Implementation of the roadmap, as conceived by the developers, should provide significant growth of the engineering industry and the formation of the domestic industrial design industry. Approval of the road map entailed the development of the target subprogram on engineering development, which should stimulate the development of instruments of state support of engineering and industrial design; preparation and introduction of profile standards, regulations and rules; creation and implementation of priority projects in the field of engineering and industrial design with the use of state support.

Every day we have to deal with mathematics. It's no wonder, because it's no coincidence that it's called the queen of the sciences. Numbers follow us everywhere and without them it is impossible to imagine the modern world.
Programming Help
There are many things I wish I had known when I started my journey as a programming student. It's been almost 10 years since then, and unfortunately, I can't share my experiences and knowledge with my past self, only with my younger colleagues. This post consists of some helpful tips that I wish I had heard when I was 18 years old.
