There is an ancient oriental tale about three smart, beloved by fate, lucky princes, wandering around the world and sometimes by chance, and more often due to their intelligence, dexterity and ingenuity, they found wonderful and useful things that they, in general, were not looking for. Princes came from the Serendip principality (as the Arabs in ancient times called the island Ceylon). There was even the term "serendipnost" - the gift of finding valuable or pleasant things that are not looking for. Serendipnost characteristic of a true scientist. In science, they are often looking for one thing, and due to chance, a happy coincidence of circumstances and insight, they find something completely different, sometimes even more important. True, the history of science testifies that this gift, as in the ancient fairy tale, inspired and deep minds are rewarded, that only brilliant insight and excellent preparation make it possible not to indifferently pass by a happy event, but to translate it into a discovery. Thus, the case, as it were, is no longer a case, and the serendipnost is not just a happy coincidence ...
