In a fascinating lecture, he discussed how the so-called Mössbauer spectrometer, which was invented in 1958 by a chemistry PhD student who received the Nobel Prize for it two years later, is used for various applications today.

Using real models and mock-ups, for example, he explained how NASA's project examined data from Mars. He also used models to demonstrate the process by which they confirmed the authenticity of an artistic painting by the painter Gustav Klimt. Professor Dr. Renz gave an entertaining explanation of the problems they encountered in their research, whether there is life on Mars and where the water came from.
This world-class scientist undoubtedly inspired many of the students present, as well as the educators.
