ETH Hangar

From Theory to Practice

In ETH Zurich’s metal workshops, student ideas take physical shape.

Thinking and calculating are essential, but real innovation also means turning ideas into prototypes. In the ETH hangars, focus project students learn how to build things themselves. But what about the "brainiacs" who can reinvent the world yet struggle to hammer a nail? Andrej Kern, head of the metal workshop in the ETH hangar, chuckles. "Sure, some have two left hands. But overall, most of them do a really good job." Kern is a big fan—of the IPZ, the ETH hangar, his work, and the students. What starts as a five-minute chat turns into half an hour as his enthusiasm spills over. "Their passion is infectious. It’s phenomenal working with them." He fondly recounts the successes of individual students and the quirks of others, like the one who starts chirping like a little bird when focused or the one who sings in hilariously off-key pitches. Through it all, Kern’s deep respect for their dedication and knowledge is always evident.

"These young people have incredible energy and drive; they really push their limits," says Andrej Kern. It’s not uncommon for them to work through the night, and their discipline is remarkable. Having spent many years in the private sector, Kern values the unfiltered, raw innovation he witnesses here. "Sometimes they come up with ideas so absurd that I can only wave them off. But other times, the ideas are SO absurd that I have to say: Let’s try it!"
