In differential geometry, a diffeomorphism is a bijective map f between two manifolds M and N for which maps f':M->N and f^{-1}':N->M exist, where f' represents the derivative of f and f^{-1}' represents the derivative of the inverse of f.

Furthermore, two manifolds are said to be diffeomorphic if there exists a diffeomorphism between them.

In the context of this repository, the manifolds represent a playground and a well-structured project respectively. I plan to ramble incoherently a lot here, and the results of my rambling may have implications with respect to finished projects. I may go backwards and reflect on what is finished.

If you are not me, I definitely welcome comments on my math and code.
