ABSTRACT
From infinitely many numbered balls, those numbered with the labels ‘1’ and ‘2’ are thrown into a room at half a minute before noon and ball number 1 is thrown out. At a quarter of a minute before noon, balls 3 and 4 are thrown in and number 2 taken out. At an eighth of a minute before noon, 5 and 6 are thrown in and number 3 taken out. And so on ad infinitum.
