We all use paper in our daily life for different purposes. But have you ever try to fold a paper more than 7 times.
If you try to fold a A4 size paper, you will be suprised to find out that, you can't fold a paper more than 7 times in terms of half.
This is because
The problem with folding paper in half multiple times is that the paper's surface area decreases by half with each fold. ... They determined that using a larger sheet of paper would make it possible to fold the paper in half more than seven times.
But imagine what will happen if you fold a paper more than 7 times 🤔🤔🤔🤔🤔🤔🤔🤔
What will happen if you fold a paper 42 times?????
If you fold a paper 42 times, the height of paper would reach the moon. It doesn't sounds true, but mathematically it is completely true.
Isn't it amazing????? How a thin paper can reach upto moon.
Let's see how a paper can reach upto moon just by folding it 42 times in terms of half.
The standard size of A4 sheet of paper is about 0.1mm thick.
If you fold a paper 1st time, the thickness of paper doubles, this means paper thickness will become 0.2mm
If you fold a paper 2nd time, the thickness of paper again doubles, this means paper thickness will become 0.4mm
If you fold a paper 3rd time, the thickness of paper will double again, this means paper thickness will become 0.8mm.
This shows that
Thickness of paper in 1st turn- 0.1mm*2^1
Thickness of paper in 2nd turn- 0.1mm*2^2
Thickness of paper in 3rd turn- 0.1mm*2^3
....
....
...
Thickness of paper in n turns- 0.1mm*2^n
Therefore,
Thickness of paper in 42 turns- 0.1mm*2^42
0.1mm* 2^42= 439,804,651,110 mm
Which is equal to 4,39,804.65111 Kilometres
Approximately 4,39,804 KM
The moon on average is about 3,84,000 KM from earth.
The above data shows that height of paper is more than distance of moon from earth, this proves the fact that
Paper can reach upto moon, if we fold it 42 times in terms of half. Preety incredible, isn't it??
From the same procedure, we observed that if we fold a paper 50times in terms of half- the height of paper will reach upto sun.
The most amazing fact is that
If you have a large piece of paper and enough power to fold it, you can halve it many times. But oops, there is a problem: if you fold the paper 103 times, the thickness of this ream of paper will exceed the known size of a universe, which is 93 billion light-years.
See how a thin sheet of paper can reach upto moon, sun and beyond a observable universe.
