I did a Masters in Maths with the OU, continuously over five and a half years. It was brutal. The percentage of people who make it all the way to to the end is savagely low (although you can cash in your chips part-way through for a lesser, but still impressive, post-graduate award).
It's guided, and the tutors are available to help, and there's the help of your fellows in the forums, but it's very much on you; this does mean that if you're motivated and persistent, you don't just get good at maths - you learn how to take a textbook and tear it into tiny little pieces like some kind of math monster.
"Here's the textbook, here's some problem sheets that will buy you a seat at the exam if you do well enough, and here's that exam - it's three hours, you'll race to answer enough questions, everything rides on it and there's five of them, plus your thesis". They were not messing around, I discovered :/
If you really are eager to learn more, and ready to challenge yourself, it's good.
> Whatever you now find weird, ugly, uncomfortable and nasty about a new medium will surely become its signature. CD distortion, the jitteriness of digital video, the crap sound of 8-bit - all of these will be cherished and emulated as soon as they can be avoided. It’s the sound of failure: so much modern art is the sound of things going out of control, of a medium pushing to its limits and breaking apart. The distorted guitar sound is the sound of something too loud for the medium supposed to carry it. The blues singer with the cracked voice is the sound of an emotional cry too powerful for the throat that releases it. The excitement of grainy film, of bleached-out black and white, is the excitement of witnessing events too momentous for the medium assigned to record them.
You might want to use `git rev-parse --abbrev-ref HEAD` or `git name-rev --name-only HEAD` instead of `git branch`. Plumbing commands (such as rev-parse or name-ref) are generally more interface-stable to use in a script than porcelain commands (such as git branch) which are designed for interactive use where output may change depending on user environment and configuration.
I've been learning representation theory (among other topics) from his Youtube lectures! They're a real treasure trove. And he's got a dry sense of humor that I quite like.
I can also recommend this interview with him by Curt Jaimungal, which is filled with his insights and opinions about his practice of mathematics, and his life as a mathematician: https://youtu.be/xu15ZbxxnUQ
