Karl Schwarzshild: astronomy, artillery, black holes
One hundred years ago, Karl Schwarzshild , the 42- year-old director of the astrophysical observatory in Potsdam and an artillery officer of the German army, made important calculations in the front-line hospital in Russia and, thanks to Albert Einstein , published two articles that paved the way to create the theory of black holes. In May 1916 , he died of bubbles. Alexei Levin read fateful texts in the original and decided to share the conclusions with readers of the TRV- science.
