15:00  Mathematical Quasicrystals And Inductive Rotation Tilings
Dirk Frettlöh, Mathematician, Technische Fakultät - Universität Bielefeld

Abstract: The discovery of aperiodic tilings (Berger 1966, Penrose 1974) and of physical quasicrystals (Shechtman et al 1984) initiated the development of a mathematical theory of aperiodic tilings ("mathematical quasicrystals"). Today this is an active field where many mathematical disciplines meet.
In 2010 the artist Hofstetter Kurt suggested a new method for generating aperiodic tilings, the Inductive Rotation Tilings. This method is of artistic interest: after a few iteration steps, fascinating novel patterns arise, and hidden patterns are generated. We applied the theory of aperiodic tilings to this new examples and obtained several results, e.g. on diffraction properties or model set properties of these tilings (F-Hofstetter 2015). This talk gives an overview on the theory of mathematical quasicrystals and how Inductive Rotation Tilings fit in.

16:00   On the Event Horizon of Order
Hofstetter Kurt, Conceptual & Media Artist, Musician and Mathematician, Vienna

Abstract: Addressing mathematics in the artistic work I have discovered new construction principles as well as new recursive methods in the field of discrete geometry. This lecture gives an overview of my artistic research work and my way of thinking and seeing, addressing the following topics. (1) Parallelism and circulation: the infinite pendulum; (2) The Sunpendulum project; (3)  New algorithms for constructing the Golden Ratio; (4) The principle of Inductive Rotation (IR): new methods for generating aperiodic and asymmetric tilings; (5) Artistic materialisations of IR tilings; (6) Moebius Sounds – Audiovisual installation dream’sdreams.

17:00   Con Espressione! Towards a New Level of Music Understanding in Computers
Gerhard Widmer, Computer Scientist, Johannes Kepler University, Linz, and OFAI Vienna

Abstract: Research in Sound and Music Computing (SMC) and Music Information Retrieval has led to some spectacular successes in recent years. However, we have barely scratched the surface of what music really is, and what it is in music that moves and speaks to us -- let us call this the expressivity of music. Computers cannot tell whether a performance expresses playfulness or ennui, solemnity or gaiety, determination or uncertainty; they cannot predict how a piece will be perceived by listeners, nor can they produce or play music with a specific expressive quality.  I will look at some of the things that computers can already do with music, and why this is still far from real musical 'understanding'. I will introduce (performance-related) expressivity as an important dimension of musical communication, will discuss and demonstrate what it means to quantify, characterise, and predict this via computer; will review recent work on computational models of performance expression; and will identify some of the big challenges that need to be solved on the way to machines that can recognise and interpret musical expressivity in useful ways.

18:00   Gotthard Günther and the Digital Revolution
Peter Weibel, Artist, Curator and Theoretician, Director of ZKM | Center for Art and Media Karlsruhe

Abstract: Recently in media theory an operative ontology takes ground. Therefore it can help to remember the more or less forgotten work by Gotthard Günther and his "Cybernetic Ontology" (1962). Already 1957 he published a book "The Consciousness of Machines" and later contributions to a Non-Aristotelian Logic.  My lecture tries to prove, how his operational dialectic could help us to understand better the contemporary digital revolution.   In addition to his talk, Peter Weibel will exhibit his installation ‘Vulkanologie der Emotionen’.

Wolfgang Pauli Lecture by Peter Weibel - ARTEMATICA 2015


The Wolfgang Pauli Lectures are Organized by the Wolfgang Pauli Institute in co-operation with Künstlerhaus Wien ; co-sponsors: TU Wien, Informatics Europe,  Zentrum für Informatikforschung.

ARTEMATICA 2015  also comprises the exhibition Body Interference (3.9. - 18.10. 2015) curated by Laura Carlotta, showing works by five artists among which Hofstetter Kurt and Peter Weibel. The exhibition will be open to the lecture attendees.
