Berechnende Kunst

Architektur (l.) und Komposition (r. unten) bedienen sich mathematischer Strukturen (r. oben). Ein Team der Uni Graz arbeitet nun an Systemen, die für die KünstlerInnen besser zu handhaben sind.

Architektur (l.) und Komposition (r. unten) bedienen sich mathematischer Strukturen (r. oben). Ein Team der Uni Graz arbeitet nun an Systemen, die für die KünstlerInnen besser zu handhaben sind.

MathematikerInnen der Uni Graz entwickeln Inspirationsquellen für Musik und Architektur

„Die Kunst bedient sich schon seit Jahrzehnten mathematischer Strukturen, um neue Formen zu finden“, erklärt Univ.-Prof. Dr. Klemens Fellner vom Institut für Mathematik und Wissenschaftliches Rechnen der Karl-Franzens-Universität Graz. Größen wie Zaha Hadid benützen algorithmische Design Software, um ihre spektakulären Gebäude zu entwerfen. Komponisten wie Jannis Xenakis oder György Ligeti bedienten sich der Mathematik, um ihre Klänge zu kreieren. „Manche der verwendeten Modelle sind allerdings so unkontrollierbar komplex, dass sie die Gestaltungsfähigkeit schon wieder einschränken“, schildert Fellner. Im Team mit seiner Kollegin Univ.-Prof. Dr. Karin Baur und Univ.-Prof. Dr. Gerhard Eckel vom Institut für Elektronische Musik und Akustik der Kunstuni Graz werden nun verschiedene Systeme mit hoher künstlerischer Inspirationskraft analysiert, die sich gezielt regulieren lassen. „Wir orientieren uns beispielsweise an Gleichungen, die beschreiben, wie sich Fischschwärme arrangieren“, so Fellner. „Manipuliert man das Verhalten einzelner Individuen, ergibt sich immer noch eine große Bandbreite an verschiedenen Ausdrucksformen, sie wird aber kontrollierbarer“, ergänzt Karin Baur. Trotz eingebauter Kontrollgrößen bleibt also die Palette an kreativen Möglichkeiten breit.

Das innovative Projekt soll nicht nur die Kunst fördern, sondern auch der Mathematik weiterhelfen. „Wir erwarten uns durch den Dialog mit MusikerInnen und ArchitektInnen neue Perspektiven und Erkenntnisse, die auch das Verständnis komplexer mathematischer Strukturen erleichtern“, erhofft sich Baur einen Mehrwert.
Das Vorhaben wird als unkonventionelle Forschung von der Karl-Franzens-Universität Graz für drei Jahre mit rund 180.000 Euro gefördert.

Learning better: Can science experiments in group settings help children with autism?

How can pupils with autism spectrum disorder (ASD) have positive learning experiences and improve their social skills? Researchers at the University of Graz are investigating how science experiments in group settings can contribute to this. Initial results from the project, which is funded by the Austrian Science Fund FWF, show that children react differently depending on the kind of neurodiversity, but that experimentation classes with the right setting definitely have potential. "Pupils with ASD can do more than is currently expected of them in many cases," says project leader Uwe Simon.

Sustainability Award 2024 for two projects of the University of Graz

How do major international conferences reduce their carbon footprint? And what can maths lessons contribute to education for sustainable development? Two questions that were answered at the University of Graz. The corresponding projects were awarded the Sustainability Award 2024 in silver on 26 November in Vienna. This award for Austria's universities and colleges is presented by the Ministry of Science and the Ministry of Climate Protection.

Bees under observation: University of Graz provides unprecedented insights into the hive

What is going on in the combs? How many eggs is the queen laying? How much honey is there? Autonomous robots and AI algorithms provide important data and high-resolution real-time images from inside a beehive. "As part of an international team, we have developed a game-changer technology for a new type of digitalised behavioural research," reports biologist Thomas Schmickl from the Artifical Life Lab at the University of Graz. The publication, which has just appeared as the cover story in the journal "Science Robotics", describes the wealth of information that can be obtained from this unique research facility.

Research for healthy aging: FWF funds Cluster of Excellence "MetAGE" with 18 million euros

Six researchers from the Field of Excellence "BioHealth" at the University of Graz, together with colleagues from the Medical Universities of Graz and Vienna, have acquired an FWF-funded "Cluster of Excellence". Now a newly formed center of excellence will be created under the leadership of the University of Graz. The aim is to gain a better understanding of healthy aging. The findings will flow directly into clinical research.
