Problem solving is one of the main stages in the assimilation of the system of mathematical knowledge by students, in particular, geometric concepts and connections between them. Solving geometric problems, students develop creativity, independent thinking, acquire skills in the practical application of the theoretical provisions of geometry. Pedagogical practice shows that solving problems that are not united by general methods does not give good results and causes great difficulties for students.

When planning a lesson, the teacher needs to draw the students’ attention to the theoretical material necessary for solving the problem, to rethink its content in practice. Such a…

The discovery of new elements of Mendeleev’s Periodic Table has always aroused interest among the general public. The point is not so much in the scientific significance of these discoveries, but in the fact that at school everyone passed the Periodic Law, and some even remember the symbols denoting the elements. This is understandable, familiar. But now these discoveries are backed by complex research in nuclear physics and radiochemistry, about which many are unaware.

chemical elements

At present, new elements are produced only at heavy ion accelerators. (Previously, they were found in terrestrial minerals, products of nuclear reactors and nuclear explosions.) Heavy…
