What happens if I fold this paper 42 times? 🤯

Описание к видео What happens if I fold this paper 42 times? 🤯

You might say that a paper can't practically be folded more than 7/8 times, but please know that I am presenting a hypothetical situation. I urge you to not miss the beauty of exponential growth by getting into practicality :)

CALCULATION:

Thickness of a paper = 0.1 mm

Thickness when folded one time = 2 x 0.1 mm

Thickness when folded two times = 2 x 2 x 0.1 mm

Thickness when folded three times = 2^3 x 0.1 mm
..
…
….
Thickness when folded 42 times = 2^42 x 0.1 mm

2^42 x 0.1 mm = 4,39,804 kilometres

4,39,804 kilometres is more than the distance between the earth and the moon which is 3,84,400 kilometres.
