Small projects to clarify big concepts

In this project, I try to clarify for myself and others the big mathematical (and not only) concepts. I try to find the simplest possible example and roll from there by asking a lot of "simple/obvious/stupid" questions. Here you can find a collection of Jupyter notebooks with different amount of content in them.

The links below will render the notebooks in nbviewer.
