# Julia sets in Julia

My first experience using the Julia language was great. Especially because it was during the 231st AAS hack day ;)

My hack was pretty simple: make pretty pictures of Julia sets in Julia :)

According to Wikipedia, a Julia set of a complex-valued entire function $f$, denoted as $J(f)$, is the smallest closed set containing at least three points which is completely invariant under $f$ (if you clearly understand what that means, please explain it to me bellow in the comments).

Julia sets can be used to create those pretty pictures (commonly known as fractals):

The code to create this “galaxy” Julia set is available on my hack-aas repository.

A very nice thing about Julia is that you can use it on Jupyter notebooks (thanks goes to Lia Corrales for telling me that), which I think makes life a lot easier for Python users.

That’s all for now folks, maybe in future I will write something else in Julia ;-)
