Introduction and functional value of origami art
1, Introduction
Origami is an artistic activity of folding paper into various shapes, and origami is not limited to paper. Origami lovers all over the world use various materials, such as tin foil paper, napkins, acetic acid tablets and so on. , while observing the folding specifications.
The combination of origami and natural science has not only become an auxiliary teaching tool in architectural schools, but also developed origami geometry as a branch of modern geometry. Origami is not only a toy, but also a thinking activity. This is a way to symbolize peace and commemoration, and it is also a way of entertainment.
2. Function value
For children, origami can exercise the flexibility of children's fingers and develop their hands-on ability and innovation ability; Origami must be done step by step.

On the other hand, modern origami is not only an art, but also a new science: origami mathematics. It has been applied to the storage of parachutes, satellite solar panels, car airbags, and even the structural design of Hubble Space Telescope has benefited from origami mathematics.
