Si algunos matem\u00e1ticos no quieren ver esa necesidad de conexi\u00f3n con la realidad, deber\u00edan hacerlo aunque fuera por una mera raz\u00f3n de supervivencia. La exploraci\u00f3n de las fronteras internas de las matem\u00e1ticas es esencial, para expandirlas, para interconectar unas \u00e1reas con otras, lo que siempre ha llevado a moverlas hacia delante.
