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.
