Episode #27: Volcano Voices

11.06.2026•41:08

Volcanic eruptions can affect the Earth’s climate system, and climate variability occupies an uncomfortable place in historical enquiry. Even though human demography and history are closely connected with environmental conditions and change, most historians and archaeologists have been reluctant to consider climate for understanding political, economic, social and cultural transformations. Much of the scholarship addressing these complex relationships continues to be constrained by the disciplinary limits of individuals and institutions.From November 2021 to January 2024 volcanologist Clive Oppenheimer and Ulf Büntgen, professor of Environmental Systems Analysis, were part of the ZiF long-term research group “Volcanoes, Climate and History”. The research group engaged with the interface of climate and history in a new way, beginning with the premise that exchange and dialogue across disciplinary and epistemological divides should be habitual practice. The research process was not only documented in scientific publications, but also in a film, entitled “Volcano Voices. From Ashes to Archives and Art”. In this Film Clive Oppenheimer leads a journey through time and ideas, where scientists and artists come together - united by curiosity and the joy of collaboration - to explore how volcanic eruptions changed climate and history.In this episode, Clive Oppenheimer and Ulf Büntgen talk about film as a means of science communication and the challenges of making complex research accessible for a wider audience.

Episode #26: The Lush World of Random Matrices

13.05.2026•48:16

Random Matrix Theory (RMT) stands out as a unifying framework at the core of seemingly unrelated fields ranging from signal processing, theoretical ecology, economics and finance, to the theory of learning and the statistical physics of disordered classical and quantum systems. Far from being a mere set of computational tools, RMT provides deep theoretical insights and a foundational understanding of various complex systems. It is key to understand the stability or fragility of complex systems with numerous interacting agents, providing a theoretical framework to capture their responses to perturbations, that may lead to significant changes in the system’s configuration with substantial rearrangements in the state of the individual components (thus describing scenarios of crises or extinctions).In this episode physicist and capital fund manager Jean-Philippe Bouchaud Paris), quantum physicist Valentina Ros and Tobias Galla from the Institute for Cross-disciplinary Physics and Complex Systems (IFISC) at Palma de Mallorca talk about their research group at ZiF and discuss the potential of Random Matrix Theory and the challenges of interdisciplinary collaboration.

Episode #25: Robust Decision Heuristics for Natural and Artificial Intelligence

15.04.2026•1:08:45

Since September 2025 the long-term research group “Robust Decision Heuristics for Natural and Artificial Intelligence” is working at ZiF. The group seeks to bridge the study of decision-making under uncertainty in natural systems and the design of robust AI systems. Here, "natural systems" is primarily a reference to humans but we will also consider insects because they have simpler decision processes. The goal of the researchers more specifically is to explore the design of algorithms for robust and transparent AI systems by drawing on models of decision processes under uncertainty in natural systems; and to explore the design of AI systems driven by decision heuristics to gain new understanding about decision-making in natural systems.In this episode the conveners of the group, Mohan Sridharan (Chair in Robot Systems, Edinburgh), Özgür Şimşek (Professor of Computer Science, Bath) and psychologist Gerd Gigerenzer (Berlin) talk about the many facets of their research, covering human decision making as well as robot soccer. They also discuss the necessity and the challenges of interdisciplinary collaboration.

Episode #24: Täter:innen in der Literatur

11.03.2026•1:09:59

In der Literaturgeschichte hat die Einfühlung in Täter:innen mit den Mitteln der Kunst eine lange Tradition. Dies bedeutet jedoch nicht, dass die literarische Auseinandersetzung mit Täter:innen zwingend zur Anerkennung von Unrecht, Entschuldigung, Entlastung oder gar zu einer Täter-Opfer-Umkehr führen muss. Gerade Marcel Beyers Roman Flughunde über die Familie des NS-Propagandaministers Goebbels und Nora Bossongs Reichskanzlerplatz, der Magda Goebbels ins Zentrum stellt, verdeutlichen, dass die Annäherung an Täter:innen in der Literatur auf eine Weise möglich ist, die eine komplexere, über Einzeltäter:innen hinausgehende Perspektive auf Schuld und Verantwortung ermöglicht. Aber warum erzählen wir uns überhaupt Geschichten über Täter:innen, welche soziale und moralische Funktion erfüllen sie? Was ist die ‚Aufgabe‘ der Literatur in diesem Zusammenhang? Und wie weit reicht ihre Autonomie? Der Literaturwissenschaftler Sebastian Schönbeck moderiert die Lesung der beiden Autor:innen und führt das anschließende Gespräch mit ihnen. Die Lesung war Teil des Workshops "A Case for Empathy? Facing the Perpetrator in Literature, Culture, and History", den die Literaturwissenschaftlerin Saskia Fischer (Hannover) am ZiF veranstaltet hat.Links:Marcel Beyer Nora BossongSebastian SchönbeckSaskia Fischer Workshop "A Case for Empathy?"

Episode #23: AI Risk and Safety Landscape

18.02.2026•46:22

With the increasing adoption of artificial intelligence (AI) methods in society, discussions about associated risks and how to mitigate them have also intensified, as evidenced by efforts to regulate AI applications in the EU and industry attempts to provide “safe AI”. However, while there appears to be a general consensus that AI-supported systems ought to be safe, we also observe fierce disagreement about which risks should be considered and what constitutes viable mitigation strategies. In other words: there is an urgent need to understand what both risk and safety mean in the context of AI.In this episode cognitive scientist Benjamin Paaßen (Bielefeld), computational neuroscientist Elizabeth Herbert (München) and Olle Häggström, Professor of Mathematical Sciences at Gothenburg University, talk about the difficulties of defining risk and safety, about the range of risks that should be considered, as well as strategies to enhance AI-safety across technical, social and legal dimensions. They also reflect on the necessity and the challenges of interdisciplinary collaboration to make progress with this endeavor.Links:Olle HäggströmElizabeth Herbert Benjamin Paaßen ZiF-Workshop "AI Risk and Safety Landscape"

Episode #22: Auf eigenen Wegen in die Moderne

15.01.2026•44:47

Der Aufstieg Europas aus dem Mittelalter in die Moderne wurde in den Geschichtswissenschaften lange durch eine besondere Veränderungsdynamik erklärt. Inzwischen sehen Historiker*innen auch Länder aus anderen Weltregionen auf eigenen Wegen in die Moderne. In dieser Folge erklären Franz-Josef Arlinghaus (Professor für Geschichte des Hoch- und Spätmittelalters an der Universität Bielefeld), Ulla Kypta (Professorin für die Geschichte des Hoch- und Spätmittelalters an der Universität Münster) und Masaki Taguchi (Professor für Rechtsgeschichte an der Juristischen Fakultät der Hokkaido Universität in Sapporo/Japan), wie sich der Prozess der Eigendynamik in Ostasien und Europa entwickelt hat. Für das Intro danken wir Niklas Schönfeld, für die Einsprecher Molina Panzner und Erica Shires und für das Podcast-Cover Corinna Mehl.
