STRUC­TURES Short Film 4: How can we efficiently and reliably identify structures in large datasets?

Click on the image to watch the video on YouTube.

In a data-abundant world, the challenge of discerning meaningful patterns becomes ever more crucial. One of the four key re­search questions of STRUC­TURES is how to reliably and efficiently uncover structures in large datasets. Our team of researchers trains specialized unsupervised neural networks to tackle the complexity of structure discovery. These AI algorithms autonomously construct what we term as feature spaces — an abstraction that comes to life through a relatable example: How do people's handwriting styles differ? Our networks possess the ability to learn and interpret distinct handwriting styles. The foundational concepts underlying these abilities can be applied to various structure discovery tasks in diverse fields, including disciplines such as medicine.

"This is a coffee mug. But for a scientist, it is so much more…" Join us on a fascinating tour through the world of geometry & topology, where intriguing links emerge between physics & mathematics. The study of these connections from an interdisciplinary angle allows us to advance understanding in both disciplines, surpassing what each discipline can achieve independently. The STRUC­TURES Cluster in Hei­del­berg offers a unique environment for scientists from diverse backgrounds to interact and collaborate. Together, our researchers synergize their expertise to drive rapid advancements, pushing the boundaries of knowledge and understanding.

STRUC­TURES Short Film 2: Understanding Complex Structures

Complicated structures emerge from simple laws applied to very general conditions. Mathematics plays a unifying role in providing very similar methods for cosmology and quan­tum fields. Our latest film, available on the STRUC­TURES YouTube channel, underlines the unique interdisciplinary collaboration within the STRUC­TURES Cluster of Excellence, in which theo­re­ti­cal and experimental methods are linked:

We are delighted to announce the first anniversary of the STRUC­TURES Science Outreach Blog and our social media channels. Under the motto What's that Structure?, the STRUC­TURES blog has been a source of knowledge, and inspiration for a broad, scientifically interested audience passionate about understanding how structure, collective phenomena, and complexity emerge from the fundamental laws of physics. Launched in August 2022, the STRUC­TURES Blog has become a platform for the exchange, transfer and discussion of scientific ideas and knowledge across diverse disciplines, including physics, mathematics, astronomy and computer science. Complementing this, we provide an extensive offer of news, information, and science communication through our active and engaging social media channels aimed at the public, members, students and colleagues.

We are proud that over the past months, in addition to gaining many new authors and presenting exciting articles, we have achieved a steady growth in visitor numbers. Our blog articles are currently accessed more than forty times a day (median over three months). The STRUC­TURES blog has found a big positive resonance also on our Social Media channels, where we count 160 Twitter and 193 Instagram followers as of July 31. In addition, with the beginning of STRUCTURES' Public Talk Series Akademische Mittagspause 2023, the STRUC­TURES Cluster has launched its new YouTube channel as a new content offer, on which you can already find a large amount of content related to the talks.

Throughout August, we will celebrate the Blog's and Social Media anniversary with various posts, movies and a special blog article . As a beginning, and to inaugurate our recently launched YouTube channel, we present one of four upcoming short movies about the STRUC­TURES Cluster of Excellence, titled "We Are STRUCTURES":

On the occasion of this anniversary, we would like to warmly thank all of our blog authors, colleagues, visitors and everyone involved behind the scenes. The STRUC­TURES Blog would not be possible without you, and the efforts of many!

Workshop: Human Intelligence Meets Artificial Intelligence, Oct 4-5, 2023

We are happy to announce the workshop Human Intelligence (HI) Meets Artificial Intelligence (AI) jointly organized by the STRUC­TURES Cluster of Excellence and Field of Focus IV (Self-Regulation And Regulation: Individuals and Societies). The workshop will take place from October 4 to 5, 2023 at Marsilius Kolleg, Hei­del­berg.

The registration is open until September 15. The link and the programme can be found at:
https://structures.uni-heidelberg.de/workshop_HI_meets_AI.

About the Workshop: Human intelligence (HI) emerges through the coordinated activity of a highly intricate and interconnected neural network, our brain. Understanding HI thus rests on understanding how this network implements cognitive processes, a question tackled by cognitive and neuro-scientists for decades. On the other hand, in the field of artificial intelligence (AI), the past few years have witnessed considerable progress in developing and understanding artificial deep neural networks. These models share common principles with the brain, sometimes even borrowing ideas from neuroscientific principles, although they also differ in important ways. As it stands, using modern AI tools to improve our understanding on HI, and vice versa, is a scientific field still in its infancy.

This workshop brings together experts on HI and AI to highlight recent progress in these areas and stimulate novel ideas bridging both fields. Our overarching questions are: How can AI help to better understand HI, how can we leverage deep learning models to explain neural mechanisms underlying HI and how can HI inspire the development of AI? Our invited speakers have focused and are currently focusing on these questions. We hope that this workshop will connect researchers on HI and AI, and identify novel collaborations between the fields.

Research: The Universal Sound of Black Holes

An international team of researchers led by STRUC­TURES member Fabian Schneider predicts that black hole mergers produce chirp sounds in two universal frequency ranges.

They are mysterious, exciting and inescapable – black holes are some of the most exotic objects in the Universe. With gravitational-wave detectors, it is possible to detect the chirp sound that two black holes produce when they merge, approximately 70 such chirps have been found so far. Based on the frequency evolution of this chirp signal, scientists can infer the so-called “chirp mass”, a combination of the two individual black hole masses. So far, it has been assumed that the merging black holes can have any mass. In their new study, published in The Astrophysical Journal Letters, STRUC­TURES Member Fabian Schneider (Hei­del­berg Institute for Theo­re­ti­cal Studies, HITS) and his team, however, predict that in this “ocean of voices”, chirps preferentially occur in two universal frequency ranges. The team's simulations align precisely with observations of the "stellar graveyard" – a collection of all known masses of the neutron-star and black-hole remains of massive stars – which reveal intriguing peaks at approximately 8 and 14 solar masses. With gravitational-wave astronomy paving the way for unprecedented insights into the cosmos, this re­search opens up a new frontier of exploration, helping scientists understand better where the singing black holes in this ocean of voices come from.
