On February 24, everything changed not only for Ukraine, but for the whole world. Russia's invasion of the territory of the sovereign state of Ukraine made it clear that no one can be immune against attack in the XXI century. Millions of Ukrainians were forced to leave their homes because of the "russian peace". Thousands of Ukrainians died, including children. The war had a negative impact on all spheres of Ukraine's activity, including science and education. It will take years, decades to restore everything with world anti-war coalition support.
