    Laser spectroscopy
    2025/04/07
    What is matter made of? If we could zoom in to unimaginably small scales, we’d see atoms and gases teeming with electrons in constant motion. Laser spectroscopy is one of the powerful tools scientists use to explore this microscopic world. Birgitta Schulze-Bernhardt will guide us through what we can uncover about the infinitesimally small and how this knowledge impacts the view of the world we live in.

    Philosophy and Physics - Part 2
    2025/03/24
    What does one mean by philosophy of physics? How can philosophy help us understand the physical world? In particular, when it comes to quantum mechanics, human intuition seems to break down. Is the wave function real, or is it just a construct we use to make sense of experiments? Is reality truly based on probabilities? In this episode we continue our journey into the relationship between philosophy and physics with Axel Maas and Philip Berghofer from University of Graz. The first part of our conversation with them can be found at episode "Philosophy and Physics - Part 1"

Is the wave function real, or is it just a construct we use to make sense of experiments? Is reality truly based on probabilities? In this episode, Axel Maas and Philip Berghofer from the University of Graz will guide us through the challenges of reconnecting the physical world with the models we use to describe it.

    Pigments colors and other shades of physics
    2025/03/03
    If sunlight is often described as "white," why do we see so many colors? How are colors connected to the wavelengths of light? And what exactly is a wavelength? Anna Galler, a researcher at TU Graz, takes us on a journey through the world of light, pigments, and the fascinating physics behind every shade.

    What if we could "kick" one electron now and have a current going on forever? Christoph Heil, Professor at Graz University of Technology, tells us that when things get really (really!) cool this is already possible. But it comes at a price...

    "More is different". The famous quote from P. Anderson. What did he mean by that? Why is interaction between particles so interesting and difficult to describe? We continue on our journey through the fascinating realm of quantum physics: this time Markus Aichhorn, Professor at Graz University of Technology, will tell us about what happens when many particles interact at the quantum level...
