Microplastics were scientific discoveries and set to practical use by humans. What humans invented that will endure even during their inevitable absence from the planet is music. This is not my conclusion, though I agree with it, but comes from an abstruse book on music by Cyril Scott which I read over forty years ago when I studied the effect of largo movement passages in concertos inducing hypermnesiac mental ability. The concept came from a doctoral dissertation completed at the University of Kharkov. You’ll notice I write Kharkov in the Russian transliterated form rather than in Ukrainian inasmuch as the city will soon be annexed by Russia, and was never known globally as Kharkiev until Ukraine became a country. I do the same with Zaporozhye which of course is the name of an Oblast and its capital city but also the name of a popular automobile manufactured in Russia.
Manufactured in Ukraine actually, but what do facts matter in your rants?
