Series of Talks »Blick über den Tellerrand«

Once every month, the Fraunhofer ITWM opens its doors and invites everyone who is interested to broaden their horizon. The interdisciplinary lecture series »Blick über den Tellerrand« of the Felix Klein Center for Mathematics presents different perspectives on a wide spectrum of topics in the area of science and technology.

Exciting experts from a wide range of fields will speak and discuss with the guests. Everyone is cordially invited and admission is free. The event will take place on site at the Fraunhofer Center and will also be broadcast virtually.

Blick über den Tellerrand (Thinking Outside the Box)

Our Tellerrand continues hybrid.

Blick über den Tellerrand in May 2023

»The Deceived Brain: Reality – Perception – Illusion«

Tuesday, 16. May 2023
5:00 to 6:30 PM

In psychology, perception falls under the term »cognition« and can be understood as the ability to receive, understand and make sense of the information (stimuli) that occurs through the respective receptors of the sense organs.

What we perceive of our environment is created by a complex interaction of sensors and our brain. Both physiological and psychological influences play a role in this process. On the long way from the reception of stimuli to the interpretation of the received signals, various »errors« can occur that distort our image of the environment. This has various consequences, such as the contradictory statements of witnesses at an accident or a dispute about the color of a piece of clothing. Advertising strategy (neuromarketing) and magicians use the »impressionable« perception for their purposes.

In a short overview with live experiments the speaker shows which possibilities of influencing there are, how to use them and how to (possibly) protect oneself from them.


Dr. René Beigang from the Rhineland-Palatinate Technical University Kaiserslautern-Landau (RPTU), Department of »Physics«.

Prof. Dr. René Beigang received his diploma and doctorate from the University of Hannover. In 1990, after his habilitation at the Free University of Berlin, he moved to the University of Kaiserslautern, where he worked as a professor in the Department of Physics until his retirement.

His initial scientific interests were in laser physics, nonlinear optics, and the generation and application of ultrashort pulses in fundamental research and biophysics. For more than 20 years, Professor Dr. René Beigang conducted research at the Technical University of Kaiserslautern (now RPTU) mainly on terahertz waves. He still likes to get to the bottom of his »favorite waves« in the laboratory.

The event will be moderated by Prof. Dr. Karl-Heinz Küfer. He is the speaker of the Felix Klein Center for Mathematics, head of the division »Optimization« and head of the department »Optimization – Operations Research« at the Fraunhofer Institute for Industrial Mathematics ITWM.
