The Mystery of Folding Paper: Can We Do More Than 8 Times?

Click For Summary

Discussion Overview

The discussion revolves around the question of why a piece of paper cannot be folded more than eight times, regardless of its size. Participants explore potential explanations from mathematical and physical perspectives, as well as considerations of practical limitations.

Discussion Character

  • Exploratory
  • Debate/contested
  • Mathematical reasoning

Main Points Raised

  • Some participants suggest that the inability to fold paper more than eight times is related to the increasing thickness of the paper and the diminishing size of the foldable area, particularly when considering the powers of 2.
  • Others propose that while humans may struggle to fold paper multiple times due to physical limitations, machines could potentially achieve more folds.
  • A participant introduces a comparison involving exponential growth, highlighting the mathematical concept of powers of 2 in relation to folding.
  • There is a suggestion that the question has been previously discussed in other forums, indicating a broader interest in the topic.

Areas of Agreement / Disagreement

Participants express differing views on the reasons behind the limitation of folding paper, with some emphasizing physical constraints and others suggesting mathematical or mechanical solutions. No consensus is reached on a definitive explanation.

Contextual Notes

Participants acknowledge the complexity of the problem, including factors such as paper thickness, dimensions, and the role of machines versus human capability. The discussion remains open-ended regarding the underlying principles involved.

folding paper

Why can't we fold a piece of paper more than 8 times, no matter how large it is?

PS I've seen this question in another forum quite a long time ago but no one seems to know why. Some claimed that it can be explained by using some chemistry principles while others said it is related to math.

Math/physics.

Try it...with standard thickness paper, it just gets too thick/small to fold. Even with a large sheet, the powers-of-2 still rapidly cut the size down and make it unfoldable. (I'm sure there's a more elegant explanation than that, but that's all I have time for at the moment!)

But I think it can be done with thinner paper.
 
If someone offered you $20 a day for a month or $.01 the first day, $.02 the second, $.04 the third, etc., which would you choose?

And how many pieces of paper would you be folding that 8th time?

Ahh, the power of exponents.

Yeah, I thought of it too when I was on my way back home from school.

However, as long as the dimensions aren't negative (and it will never be negative by folding), I think we can fold it, not by human but by machines. I think it is we who aren't strong enough to fold it, but not machines.

Well, 2 to the power of 30 is roughly 1,000,000,000
so you would make roughly $20, 000, 000 the second way versus $600 the first.

I know which one I would choose.

do we know it's impossible. they should make a machine do it. you know, without stubby little fingers!
