How does light enter the world?
How does light enter the world?
Prof Dr Mathias Wickleder
Institute of Chemistry and Applied Chemistry
It is impossible to imagine our world without light! While our ancestors still had to follow the natural rhythm of night and day, we simply switch on the light! And today this light no longer comes from a simple light bulb, as it was invented 110 years ago, but from sophisticated and highly developed light sources such as "halogen lamps", "xenon lamps" or "LEDs". There is a lot of chemistry in these modern lamps! The lecture uses many experiments to show which chemical reactions are important. But you will also see that even some animals - such as fireflies and luminous fish - manage to bring light into their world!
