►modernbrain: https://modernbrain.de (advertisement) In the 19th century there lived a mathematician who was so brilliant that even the great genius Albert Einstein would never have become so famous without his preparatory work. His name was Bernhard Riemann. Not only did he develop the theory of curved spaces, without which Einstein would probably never have been able to develop his theory of relativity, but he was also a genius in almost all other areas of mathematics. Riemann's work was so brilliant that today a million US dollars prize is awarded for proving or disproving the so-called Riemann conjecture about the distribution of prime numbers. Riemann also studied the nature of mathematical infinity in depth. In doing so, he discovered something absolutely paradoxical. He showed that if you subtract infinity from infinity, you get exactly pi. How can that be? Where does this strange connection come from and how can you subtract infinities from each other? It is the Riemann rearrangement theorem. ►All videos: http://bit.ly/1fa7Tw3 ✚Snapchat: SekundenPhysik ✚Facebook: http://on.fb.me/YJFlNt ✚Subscribe: http://bit.ly/10jgdi2 More on the topic: Riemann's rearrangement theorem: https://de.wikipedia.org/wiki/Riemann... 100SekundenPhysik: this is science in a simple, concise and entertaining form.
