Bernahrd Ganter

TU Dresden, Germany

Bernahrd Ganter is an emeritus professor at the Technical University of Dresden. He is a pioneer of formal concept analysis and he studied its applications in computer science, especially in data analysis and knowledge processing. Bernahrd Ganter was a member of the team of Rudolf Wille, a fameous contributor to mathematical music theory, and he was involved in the development of the experimental musical instrument Mutabor. Professor Ganter is the founder and an author of many pieces on exhibition of the mathematical museum Erlebnisland Mathematik in Dresden.

Jerzy Pogonowski

Adam Mickiewicz University, Poland

Jerzy Pogonowski is a professor at the Department of Logic and Cognitive Science at the Adam Mickiewicz University in Poznań. He is an author of more than a hundred papers devoted to applications of logic, methodology of science and philosophy of mathematics. Some of his recent publications are devoted to mathematical education on the university level. He teaches mathematics, mathematical logic, mathematical problem solving and general linguistics at the Faculty of Psychology and Cognitive Science of the Adam Mickiewicz University in Poznań.

Karl Schaffer, Erik Stern

De Anza College, USA, Weber State University, USA

Karl Schaffer is a mathematician and dancer. He teaches mathematics at De Anza College in Cupertino, California. Erik Stern is a musician, dancer, and interdisciplinary educator. He is a Professor of Dance at Weber State University in Ogden, Utah. Karl and Erik form the dance company Dr. Schaffer and Mr. Stern Dance Ensemble, world-famous for its performances and workshops on math dance. They performed in schools, museums (e.g. the Momath in New York, the National Science Museum in Seoul), at math and art conferences. Their book “Math Dance with Dr. Schaffer and Mr. Stern: Whole body math and movement activities for the K-12 classroom” unifies concepts in both mathematics and dance. (The photo was taken from from

Jan Świerkowski

Catholic University of Portugal

Jan Świerkowski is a curator interested in the Art and Science of Visualizing the Invisible, with a focus on astronomy and physics. He is the leader of artsci ensemble Instytut B61, repeatedly exhibited in Poland, Portugal, Estonia, Latvia, Lithuania, and India. Instytut B61’s projects include large-scale site-specific immersive performances, pop-up exhibitions, and disruptive digital storytelling. Jan loves art, science, and trains. He was the head of Cosmic Underground, an artistic railway journey from Estonia to Portugal. Under his guidance 40 artists, scientists and designers traveled for 2 months throughout Europe by an adapted cargo train composed of 10 wagonstallations, in which an immersive exhibition about the Special Theory of Relativity was installed. He is a director of a creative cluster and co-owner of a Nicolaus Copernicus University spin-off focused on edutainment. Jan is also a researcher at the Center for Communication and Culture in Lisbon and a guest researcher at the Department of Arts and Cultural Studies at the University of Copenhagen.
