Many things can be folded with a piece of paper, such as roses, lilies, stars, zongzi, paper cranes, clothes, trousers, phoenix, frogs, paper planes, lotus flowers, triangles and so on.
What can be folded with only one piece of paper? How to fold
I like folding love.
A piece of paper, a sheet piling, what kind of paper can you say?
Sheet piling, some paper.
A piece of paper can be folded in half at most. What is the reason?
This is mentioned in the Galileo laboratory of Japan's science and technology plan.
It seems that the fibers of the paper overlap and are very tough.
Thinking for a day
It's really because the fibers of the paper overlap.
The fiber overlap thickness of paper is equal to the toughness of paper multiplied by the ninth power of 2, which makes the fiber overlap of paper reach a very large data.
It seems that one match is easy to break, but it is difficult to break a hundred matches.
In Galileo's laboratory, a very large piece of tissue paper, the size of a basketball court, was used for experiments, and it ranked ninth. It's still on the tenth floor, and there's no way to fold it.
What pattern can a piece of paper be folded into?
too much
Is there any way to fold a piece of paper into three equal parts?
Suppose the four corners of this paper are ABCD:
First, fold ABCD in half along the dotted line in the figure, and then fold it into 4 equal parts:
Find the intersection of the broken line and the edge: g, e, I, h, f, j:
Fold BD in half along IJ to make it coincide with EF:
Get rectangular AIJC, as shown in the figure:
Fold in half along the diagonal AJ of the rectangle AIJC, and the fold line passes through the GH and EF creases at K and L:
Open BD and restore to the original rectangular ABCD:
Fold AB edge along the graphic folding line MN passing through k, and fold CD edge along the graphic folding line OP passing through l:
Then folds MN and OP will divide the paper ABCD equally:
How many times can a piece of paper be folded at most?
7 ~ 9 times

What flower can a piece of paper be folded into? It's better to keep it simple.

No matter how big a piece of paper is, how many times can it be folded repeatedly?
New record of origami: 13 times. What is the technical content of folding a piece of paper in half in the same direction? In fact, this seemingly simple action is actually very complicated. Anyone can easily fold it twice, three times or four times, but how many times do you think you can fold it? If you think a dozen times is a piece of cake, congratulations on making a small mistake in math, because you forgot that terrible index. You know, after each folding, the thickness of the paper will be doubled, which is equivalent to the original square, while the area of the paper will be reduced by half. The exponential growth is very terrible, so the thickness of the paper will be 2654,38+00 times, that is, 654,38+0024 times, and the area will be reduced to a quarter of the original 654,38+0024 times. Knowing this long background, you can understand the achievements of teachers and students in St. Mark's Middle School in Texas, USA: They folded a piece of toilet paper with a length of 1.3 thousand feet (nearly 4 kilometers) in half 1.3 times, breaking the old record set in 2002-1.2 times in one fell swoop. The folded toilet paper 13 times has 2 layers 13 = 8 192, which is not very beautiful when it is shrunk into a big ball, so it cannot keep this shape for a long time.
