I ran across this little gem recently: > Git gets easier once you get the basic idea that branches are homeomorphic endofunctors mapping submanifolds of a Hilbert space. * Isaac Wolkerstorfer, https://twitter.com/agnoster/status/44636629423497217

Richard Feynman had a joke theory that any purely theoretical mathematical concept when expressed in layman's terms devolves into something completely obvious. So does this actually mean something like "git uses branches."?

Is that maths soup or a real construct? I can't join the dots but I'm also studying physics so category theory is still slightly Greek to me (I can feel the mathematicians' noses rising already...)

It's a joke. A well-discussed one.

tl;dr it's a random math soup (from first link)

I have never got all these jokes. When my job switched from Subversion to git it took me about one week plus reading a couple of articles to become more productive in git than I ever was in Subversion. Yes, version control is a bit tricky but git is not that hard to understand and was much easier than contemporary Subversion versions.

Definitely helped a bit. I just graduated from university and am working full time as a developer now. I thought I knew how to use git because I knew how to do feature branching and merging. Boy was I wrong. Within a few weeks at my new job, I've realized that I'm missing so much useful git knowledge. When I learned about cherry-pick, my mind was blown.

My goal right now is to develop a better mental model of git than what I have right now. If anyone has recommendations for resources, please let me know!
