    How does a star like our Sun actually work? What fuels this giant ball of gas—and how does it change over time? And where do the elements of the periodic table really come from?
    In this episode, we explore these cosmic questions with our guest, Professor Alexander Shapiro from the University of Graz.

    What is biophysics? What does it study, and why is it so difficult to apply physics to predict the behavior of living organisms? Professor Douwe Bonthuis from Graz University of Technology takes us on a journey through the fascinating, yet complex, world of biophysics.

    What if we told you there is a fourth state of matter all around us—one that powers neon signs, lights up the aurora and fuels fusion reactors? Christopher Albert, from Graz University of Technology, will help us unravel the mysteries of plasma: why it is so hard to tame, where it hides in nature, and how mastering it could revolutionize the way we think of energy.

    Have you ever heard about Guglielmo Marconi? Ever wondered how we can communicate with satellites in orbit around Earth efficiently? And also, how many satellites are "up there"? These is just a short selection of the questions we ask in this episode. With us to discuss about "Space and satellite communication", Mirela Fetescu, researcher and engineer at Joanneum Research, in Graz.

    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.
