Markus Suta of Heinrich Heine University Düsseldorf speaks with Tom Götze-Ebert about inorganic photoactive materials and phosphors spanning infrared to ultraviolet wavelengths. The episode examines material choices for lighting, approaches to improving environmental performance and the use of luminescence to measure temperature.

Humans are very good at visually recognizing materials and inferring their properties. Without touching surfaces, we can usually tell what they would feel like, and we enjoy vivid visual intuitions about how they typically behave. This is impressive because the retinal image that the visual system receives as input is the result of complex interactions between many physical processes. Somehow the brain has to disentangle these different factors. I will present some recent work in which we show that an unsupervised neural network trained on images of surfaces spontaneously learns to disentangle
