Public Lectures

Tübinger Sommeruniversität 2009: "Farbe - Wahrnehmung oder Illusion? Wie unser Gehirn die Welt in Farbe taucht„. [Tübingen Summer University 2009: "Colour - perception or deception? How our brain colours the world."]

Note: Reading out aloud the names of colours is difficult when the colour names do not correspond to their perceived colours (see text on the right)

Kinder-Uni Forscher Tag 2007, Tübingen: “Warum wir unseren Augen manchmal nicht trauen können…„ ["Why we can’t always trust our eyes..." Lecture and experiments for children aged 8-12 on how our visual system works and why it can be tricked. July 7th 2007, University Eye Hospital Tübingen.]

Note: The hat is as wide as it is tall, and the elephant has an impossible number of legs!

Lange Nacht der Wissenschaften “Sehen: Wirklichkeit oder Täuschung?„ ["The world as we see it: reality or illusion?“ Demonstrations of some of the most powerful visual illusions.] July 5th, 2005, University Hospital Tübingen.

Note: All the concentric lines are in fact proper circles, and on the right hand side the square A and B noth have the same luminance ... they are photometrically identical, but not identical in our perception.
