Origami: from art to space engineering

Origami has more than 400 years of documented history in Japan, although the folding of paper as an artistic practice is much older in Asia. For centuries it was primarily an aesthetic and ritual discipline. Its transformation into an engineering tool is surprisingly recent: the first serious scientific applications came in the second half of the twentieth century.

The core point that interests engineers is not the paper but the geometry. A folded object can occupy a tiny fraction of the space it would take up unfolded, and can unfold in a controlled and predictable way. For satellite solar panels, that is critical: they need to fit inside a rocket during launch and unfold perfectly once in orbit. The Miura-ori design, developed by Japanese astrophysicist Koryo Miura, became an industry standard in aerospace.

In medicine, the same mathematics allow the design of cardiac stents that are inserted compressed and expand when they reach the right site. In automotive engineering, airbags use folding principles to deploy in milliseconds with precision. What began as ceremonial art ended up being a problem in applied mathematics with very concrete consequences.
