Why not get acquainted with the university in childhood? The Children's University makes it possible. In lectures lasting one hour on average, professors answer exciting knowledge questions. Since 2007/2008, both universities offer one or two lectures each semester for children between the ages 8-12.
Harry Potter had one, and so did Siegfried, the hero in the German legend the Nibelungensage. A cloak that can make you completely invisible? It might sound like something right out of a fairytale, but in the field of optics, research is currently being carried into exactly this topic. Is it really possible to make things invisible? Can light really be guided around objects?
Refraction changes the path of light. This can be seen, for example, if you hold a stick in water and it suddenly looks bent. Using the newest nanotechnology methods, it is possible to construct materials and customize the refractive index so that light can be steered slightly to go around objects.
In this lecture for the Children’s Uni Prof on June 15, Harald Giessen will be explaining how refraction works and how it might actually be possible to make an invisibility cloak.
