The 11th graders of secondary school No. 201 of Minsk made a journey from school classrooms to the world of big science. High school students visited the United Institute of Informatics Problems of the National Academy of Sciences of Belarus with an educational excursion. The visit was initiated by geography and astronomy teacher Mikhail Vladimirovich Asadchii, who sought to help his students consolidate complex topics in astronomy and see how the theory works in practice. The schoolchildren's visit became part of an important work on the popularization of science. The purpose of the excursion was to get acquainted with the practical achievements of Belarus in the field of remote sensing of the Earth and supercomputer technologies. First, the high school students got acquainted with the work of the Geoinformation Systems enterprise, then they visited the research department of the Republican Supercomputer Center for Collective Use, about the work of which the chief designer of the project Alexander Rymarchuk told the children in detail. The excursion to OIPI destroyed the stereotype of science as something exclusively theoretical. For the institute, such meetings are an opportunity to show that science can be exciting and accessible, and for schoolchildren, it is a chance to decide on a future profession at the intersection of high technologies and research of our planet. Thank you to the 201st school for your interest in exact sciences. OIPI NAS of Belarus is always glad to open its doors to those who want to build the country's digital future.
