In his talk, which will be in German, Prof. Beutelspacher will explore how simple materials can be used to create objects and experiments. The event is organized by the Research Station Geometry + Dynamics, with support by the STRUCTURES Cluster of Excellence.
Abstract:
Ausgehend von der Formel des Pädagogen Pestalozzi, die das Lernen "mit Kopf, Herz und Hand" thematisiert, werden aus einfachsten Materialien Objekte und Experimente hergestellt ("Hand"). Wenn man diese Objekte sorgfältig gestaltet, treten automatisch Fragen des Zusammenpassens und der Übereinstimmung von Kanten, Flächen und Winkeln auf ("Kopf"). Und da jedes dieser Objekt ein Erfolgserlebnis verspricht, entstehen auch positive Gefühle ("Herz"). In dem Vortrag werden Experimente zu Körpern (etwa zum Tetraeder und Dodekaeder) und zu Zahlen vorgeführt und auf den mathematischen Hintergrund und das didaktische Potential eingegangen. Ein Vortrag, der für alle Altersgruppen geeignet ist und sowohl Erkenntnis als auch Unterhaltung bietet.
The talk is free of charge, a registration is not necessary.

About Scientific Machine Learning
Scientific Machine Learning is a collaborative initiative by the Interdisciplinary Center for Scientific Computing (IWR) and the STRUCTURES Cluster of Excellence. Its mission is to foster interaction and exchange within the local machine learning community, and to support its development by consolidating activities and resources that might otherwise remain scattered across individual institutions or disciplines. The initiative aligns closely with the objectives of STRUCTURES, which aims to advance fundamental research, and with IWR’s focus on applying machine learning to address long-standing challenges in the natural and life sciences, engineering, and the humanities.

From Massive Stars to Gravitational Waves: Michela Mapelli Secures ERC Advanced Grant to Decode Black Hole Origins
Michela Mapelli, STRUCTURES Professor of Computational Physics, receives an ERC Advanced Grant
An ERC advanced grant has been awarded to Michela Mapelli, Professor of Computational Physics at the Centre for Astronomy of Heidelberg University (ZAH). Her project “IMBLACK: Intermediate-Mass Black Holes in the Era of Gravitational-Wave Astronomy” aims to study the formation of intermediate-mass black holes with a mass ranging from 100 to 10'000 times the mass of our Sun.
“Black holes in this mass range are the most enigmatic.” – says Michela Mapelli – “We need them to explain the formation of supermassive black holes lying at the center of most galaxies, but their observational evidence is still scant, and their origin is puzzling. Gravitational-wave and electromagnetic measurements are starting to probe this mass regime, and the next-generation gravitational-wave detectors (Einstein Telescope, Cosmic Explorer, and LISA) will capture their mergers across almost the entire Universe. But even if we had such data tomorrow, we would not be able to interpret them, because theoretical models are still too uncertain.”
To gain insight into the formation of such enigmatic objects, IMBLACK will generate an ambitious set of models of very massive star evolution, runaway stellar collisions, and hierarchical mergers of binary black holes in dense star clusters across cosmic time. The new models will be compared against the data from ground-based gravitational-wave detectors (LIGO-Virgo-KAGRA) and electromagnetic candidates, including the one recently discovered by Heidelberg researchers in the Galactic globular cluster Omega Centauri.

The European Research Council (ERC) has granted STRUCTURES member Wolfram Pernice an ERC Advanced Grant.
Physicist Wolfram Pernice works in the field of photonic computing on artificial neural networks, which use light instead of electrons for data processing and data communication. His current research aims to link these new technologies with processes of probabilistic computing. It involves machine learning models which, unlike determinist approaches, work with probability statements and use noise as a resource.
The project aim is to develop hybrid integrated photonic circuits that use physical randomness for ultrafast computing. This is expected to enable optical computers performing at operation rates well beyond the limits of conventional digital computing. For his ERC project “Probabilistic Photonic Computing” (PICNIC) Prof. Pernice is to receive just under 3.5 million euros in funding. The scientist has been Professor of Experimental Physics at Heidelberg University since 2021 and heads the working group on neuromorphic quantum photonics at the Kirchhoff Institute for Physics (KIP). For his research on information processing and rapid computation using light he was awarded the German Research Foundation’s Gottfried Wilhelm Leibniz Prize for 2025. The Advanced Grant marks the second time he has received funding from the ERC, after having been awarded a Consolidator Grant in 2016.
