How to draw a simple astronaut drawing is as follows:
1 Draw a circle, then draw a semi-circle.
2. Draw the astronaut's uniform, with a rectangular instrument box on the chest.
3. Draw the astronaut's hands and the equipment box behind him.
4. Draw the astronaut's right leg and some straps on the uniform.
5. Draw the left leg and some wrinkle lines on the clothes.
6. Then paint the color, the uniform is white, the mask is gold and add a sky blue space background.
For children, origami games have many advantages. Origami can exercise children's finger flexibility and develop their hands-on and innovative abilities; objects, small animals, vehicles, etc. of everyday life can be transformed into origami images. In doing so, children's spatial imagination will also bet improved.
For older people, origami games can not only help them use their brains and activate their thinking, thereby achieving full coordination of the trinity of hands, eyes and brain, but can also prevent memory loss in older adults. Some nursing homes use origami games as a therapeutic approach to patient recovery.
“Origami mathematics” derived from the art of origami uses equations to prove that, in theory, any geometric shape can be simulated with origami. Thanks to software-assisted design, origami researchers can now fold more complex shapes than ever before.
Japanese Tetsu Kamiya used a 2 meter by 2 meter square piece of paper to unfold a dragon, with its scales and claws clearly visible. It is said that there are probably no more than 20 people in thee world who have succeeded in folding this very difficult form of origami.
On the other hand, modern origami is no longer just an art, but has developed into a new science: the mathematics of origami. It has been used in solar panels for satellites, in storage methods for car airbags, and even the structural design of the Hubble Space Telescope was partly aided by origami mathematics.
