Earlier quoted context omitted.

It's cute that the article is littered with Amazon referral links to textbooks.

I'm curious why people care about articles with referral links. It's not like you're paying more if you end up buying something, is it?

It is always good to know when someone is profiting financially from a recommendation they're giving you.

The main thing to remember is that nobody learns mathematics to any significant depth by reading. The only way to learn it is by doing it. Doing it carefully, and in full detail, not falling into the trap of "and I understand it from there". So the biggest barriers to doing it on your own aren't source material (there is lots of that) it's a good source of correction. There is also the usual problem of self study, in…

>That said though, one advantage if you are diligent is that you probably by necessity learn techniques of checking your work (formally and informally) earlier than typical students, which is a good thing.

Or you can post them on math stackexchange and get feedback for free from bored? mathematicians :)

>There is also the usual problem of self study, in that you don't have a roadmap and can waste time easily. Can you expand on what you mean by "roadmap"? To me, a roadmap is very easy to get and can be arrived at from different angles. method 1) Pick up an "Advanced Mathematics" book and start at page 1. The sequential chapters of that book would start a roadmap. If page 1 looks incomprehensible, look at the preface/…

The usual problem in self study (of any subject) is that you go towards what is easily accessible from where you are right now, which means you might miss out on useful avenues visible to someone who already has a good view of that "lay of the land", so to speak. You may also lack the discipline to push through something that is difficult for you when you can't see they payoff - an outside influence could convince you it will be worthwhile. Depending on the type of student you are, you can also spend too much time inefficiently on things that are comfortable.

You can try and do something like recapitulate the core curriculum of a math degree, say, but there are constraints there you aren't aware of and it won't be the right path for everyone.

method 2 expanded to "actually ask questions at some of these locations" is actually a good way to inject some outside direction. So it's a mitigation for this problem.

Amazing how thorough the Math curriculum is in the UK! I got a minor at my undergrad just by doing stats, linear algebra and calc through multivariate. I think I was just 2-3 courses shy of a BA in the subject. I'm curious how many people have met self-trained mathematicians in real life. I know there are storied examples, but is it feasible? (Compared to say - self-trained programmers or writers)

> I got a minor at my undergrad just by doing stats, linear algebra and calc through multivariate.

I wouldn't call this a good thing; this just seems like a sane basis for any maths work (including Comp Sci).

That's my point. It was pretty much what was required for the CS degree. The UK standard is much higher.

I know that many learn programming themselves but I'm curious if anyone have learn advanced mathematics this way.

I don't know if my journey can be called self study. I keep taking classes at community college when I can. I am not a fan of the emphasis on technique over understanding concepts but staying on track is hard when I try to do it all alone!

The same could be said of programming, or anything really.

This is probably the reason why there are so many more autodidact programmers than mathematicians. When programming, you know if you made an error as soon as you try to run your code. The program, by definition, must be "correct" in order to execute. The "source of correction" is the error detection built into any programming language runtime or compiler. No such "source of correction" exists for mathematics, and tha…

Good point and great analogy, though I think EWD might be turning over in his grave. While the error detection built into compilers and the testing process are, in general, indispensable tools for developing stable software, a program that executes without any evidence of error is a great distance from a program that has been shown to be correct.

To a degree. It's particularly true of mathematics.

The CS parts (which you can view as a branch of mathematics) of programming certainly have this feature.
