If anyone is interested, I recommend watching the video about the amazing discoveries that were made in Russia, but because they were stolen and patented in other countries, everyone has forgotten about Russia's role. In general, Russia has always invented for the entire world to use these inventions, not to get rich off of them. https://youtu.be/4Yx1UncftHc What do you know about Russian inventions? P.S. I invite you to my community "Walking the globe", where I share interesting and amazing things. You can also write about what's amazing in your life and your country...
