Juleorigami

Det eneste man trenger for origami, er materiale som kan brettes. Som oftest papir, men ikke unntaksfritt. Materialet må være flatt for at man skal kunne bruke origami-teknikker på det.

Origami har bidratt til viktige resultater i matematikk?

• A very general result states that any planar straight-line drawing may be cut out of one sheet of paper by a single straight cut, after appropriate folding (Demaine et al. 1998, 1999; O'Rourke 1999).
• Another result is that any polyhedron may be wrapped with a sufficiently large square sheet of paper. This implies that any connected, planar, polygonal region may be covered by a flat origami folded from a single square of paper. Moreover, any 2-coloring of the faces may be realized with paper whose two sides are those colors (Demaine et al. 1999; O'Rourke 1999).
