[Todos] conferencia sobre matematica y musica (recordatorio)

[Pablo Amster]

El proximo martes 26 de agosto a las 15 hs el Dr. Michael Winter
(compositor/Ph.D. in Media Arts and Technology) dara una conferencia
titulada "Algorithmic Information Theory, Metabiology, Music" en el
aula 9 del pabellon I. Estan todos cordialmente invitados.


Algorithmic Information Theory, Metabiology, Music

Epistemological concerns can quite naturally be framed in an artistic
discourse. The problem of reconciling the limits of
knowledge/computation with our current technological limits extends to
the practical world of making art (e.g. the current inability to
approximate Chaitin's Omega beyond a limited number of digits because
of a lack of computational resources). However, just as Algorithmic
Information Theory and Metabiology challenge the very way we explore
mathematics, they also provide a new, alternative context in which to
create and analyze art.

In this talk, I will discuss the intersection of mathematics and music
in my work focusing on how epistemological ideas influence my
practice. The talk will have a trajectory going from the generative to
the analytical and back. I will start by discussing how several of my
musical problems could be solved by graph theoretical analogs followed
by my attempt to transform these techniques for musical analysis. By
exploring the limitations of computer models developed to compare
musical structures, I draw conclusions that correspond directly to the
incompleteness results of mathematicians such as Kurt Gödel, Alan
Turing, and Gregory Chaitin. My survey of structural metrics reveals a
fundamental tradeoff of objectivity for practicality in structural
analysis. Nonetheless, these ideas provided me a totally new artistic
perspective and have been a great inspiration for several recent
pieces such as 'for gregory chaitin' (a musical setting of Chaitin's
Omega), 'Approximating Omega' (a musical setting of an adapted text by
Chaitin and the computer program that approximates Omega), and
'quieting rooms' (an installation where a genetic algorithm attempts
to put two signals out of phase and quiet a room). By discussing these
pieces and others, I will elucidate the practical and aesthetic
challenges of integrating these ideas artistically.
