- I continued to practice the method I had set for myself. In addition to following its rules for all my thoughts generally, I set aside certain hours specifically to apply the method to solving mathematical problems or even to questions from other sciences.

- Russo-Ukrainian War (Wikipedia)
The Russo-Ukrainian War is an ongoing international conflict between Russia and Ukraine, which began in February 2014. Following Ukraine’s Revolution of Dignity, Russia annexed Crimea from Ukraine and supported pro-Russian separatists fighting the Ukrainian military in the Donbas war. The first eight years of conflict also included naval incidents, cyberwarfare, and heightened political tensions. In February 2022, Russia launched a full-scale invasion of Ukraine and began occupying more of the country.
