Hans U. Fuchs studied physics at ETH Zurich and RPI in Troy, NY, before working in the industry. He did research in astrophysics, geophysics, and solar energy engineering. He taught introductory physics and systems design for engineering students from 1983 to 2017 and has been a lecturer in physics education since 2017 at the Free University of Bolzano. He is the author of The Dynamics of Heat (2nd ed., Springer, New York). Federico Corni studied physics at the University of Modena and Reggio Emilia in Italy. Initially, he was involved in research in solid-state physics and then gradually moved to research in physics education. In 2002, he became an associate professor in physics education and in 2019, he joined the Free University of Bolzano as a full professor. His interests include curriculum development for student teachers, production of teaching materials and classroom experimentation.
