Black hole by ramanujar

While on his deathbed in 1920, Ramanujan wrote a letter to his mentor, English mathematician GH Hardy outlining several new mathematical functions never before heard of. In his own words – “While asleep, I had an unusual experience. There was a red screen formed by flowing blood, as it were. I was observing it. Suddenly a hand began to write on the screen. I became all attention. That hand wrote a number of elliptic integrals. They stuck to my mind. As soon as I woke up, I commited them to writing.” In the last 90 years, nobody understood what his theorem was, but they knew it was something tremendous. Only in 2010 did they find out that this theorem describes various behaviors of black holes. Ninety years ago, no one was talking about black holes, the term did not even exist, but Ramanujan made a mathematical impression for it sitting on his deathbed and he said ‘my Devi’ gave it to me. When Ramanujan says, ‘Devi gave it to me’, for him Devi i...
