Here is the fastest of my proved formulas for p (3 digits per term) written in a popular form. I proved it in 2002 by the WZ-method.

 

 

 

 

 

 

 

 

 

 

And here is the fastest of all my formulas for p (5 digits per term). It has not been proved yet. I found it in 2003 using the PSLQ algorithm.

Para descansar podemos entretenernos con alguno de los estupendos videos de divulgación científica que podemos ver en Redes.  

Otra posibilidad aún más relajante puede ser ver las bonitas fotos de los viajes de mi sobrina en  La web de Guru y Jota.
