-The "Logic" course. A very popular and useful course for children aged 9 to 18 (the programs are different, of course). The course lasts at least one academic year, classes 1-2 times a week. Logic is the basis for the formation of critical thinking and the study of all scientific disciplines. - Special courses in physics (astrophysics, chemical and biological physics, etc.), mathematics (differential and integral calculus, numerical modeling, etc.) - «Advanced Mathematics and Physics». A separate course that I have been teaching for 3 years in Riga for students from different schools. We study using MIPT-MIT materials. Classes 1-2 times a week.
