Abstract<\/h4>\n

Are the digits of pi \u00abaleatory\u00bb numbers? Probably yes… but it is not known: it constitutes an important open problem. It is not even known whether of not, for instance, numbder 3 appears infinitely many times in the decimal expansion of pi. In this talk we will show how to represent any real number in any base as an \u201caleatoy path\u201d. This representation allows us to visualize any number and measure the \u201caleatoriness of tis digits\u201d. Among the many images to be shown, we point out which probably is the larger mathematical image produced until this moment: a path created from a hundred billion digits of pi in base 4. The image has a resolution of 108 gigapixels and is receiving an important attention from the media.

Brief Bio<\/h4>\n

Francisco Javier Arag\u00f3n Artacho is graduated in Maths from the University Alicante (Spain) in 2002 and Ph.D. from the University of Murcia (Spain) in2007. He has performed predoctoral visits at the French Antilles and the USA. After working for a business, he got a post position at the University of Alicante supported by the program \u201cJuan de La Cierva\u201d, and since 2011 he is Research Associate in Australia. He is interested in optimization and variational analysis, not forgetting the computational aspects. <\/h4>\n

Resumen<\/h4>\n

\u00bfSon los d\u00edgitos de pi n\u00fameros \u00abaleatorios\u00bb? Probablemente s\u00ed… pero no se sabe: se trata de un importante problema abierto. No se sabe, tan siquiera, si por ejemplo el n\u00famero 3 aparece un n\u00famero infinito de veces en el desarrollo decimal de pi. En esta charla mostraremos c\u00f3mo representar cualquier n\u00famero real en cualquier base como un \u00abcamino aleatorio\u00bb. Esta representaci\u00f3n nos permite visualizar cualquier n\u00famero y medir la \u00abaleatoriedad de sus d\u00edgitos\u00bb. Entre las muchas im\u00e1genes que mostraremos estar\u00e1 la que probablemente sea la mayor imagen matem\u00e1tica producida hasta este momento: un camino creado a partir de cien mil millones de d\u00edgitos de pi en base 4. La imagen tiene una resoluci\u00f3n de 108 gigap\u00edxeles y est\u00e1 recibiendo una importante atenci\u00f3n medi\u00e1tica.
