Chaos theory studies chaotic systems (see gif for an example).
This means that very small changes to the initial status have a large impact on the later course of the system. However, the system will always stay within certain boundaries and keep changing, for example if you place a ball on top of a hill and it could roll down on both sides, that system is not chaotic.

The sensitivity to initial conditions is called the butterfly effect in pop science.

Hello /sci/, anyone familiar with infinite products here?

For some reason my book says

<div class="math"> \left(1 + 240q^2 + ... \right)^3 \cdot \prod_{n=1}^{\infty} \left(1-q^{2n} \right)^{-24} = 1 + \sum_{n=1}^{\infty} c_n q^{2n} </div>

for some natural c_n. <span class="math"> q = e^{\pi i z} [/spoiler] , these are fourier-series. the first sum hast only natural coefficients. since there are no further explanation it must be some kind of trivial but i have no idea why this is obvious or how to prove that. i mean the product ist holomorphic if Im(z) > 0 but why are the coefficients natural? does anyone have an idea?

okay i have this huge list of numbers like "123456789","123456","987456321","123654".......................................................................................................................................................................................................................................................................................................................................................................................................................................................................
and i want to format it to sth like this
"123456789",
"123456",
"987456321",
"123654",
........
..........
...............
...
what is the easiest way to do this??? and we are not talking about hitting space or shit
im shure you /sci/ folks know what im talking about
